Metalworking training report in 2020 1500 words

Training is a very important link in the university, so we must pay enough attention to it, so as to help the future work. The following is the "2020 Metalworking Training Report 1500 Words" compiled by me, for your reference only, and you are welcome to read it.

2020 metalworking training report 1500 words (1) The two-week metalworking practice has come to an end. Recalling the dribs and drabs of these two weeks, I really gained a lot and felt a lot. Here, I realized a lot of joy of success, and also let me understand that behind success, I have to pay sad sweat. In this vast world, I find that college students have too many shortcomings and too many things worth going.

Metalworking practice is a highly practical technical basic course, and it is the basic technological method and technology for engineering students in colleges and universities to learn mechanical manufacturing. After this metalworking internship, I have greatly improved in many aspects, and the most important thing is my practical ability. The school just instills theoretical knowledge into us. This metalworking is to return our theory to practice and make us closer to life and society. In addition, teamwork ability is very important. Many things are difficult to accomplish by ourselves, and even if we can, it will take a lot of time. As the saying goes, there must be a teacher in a threesome. Many times before, I was a loner. I went to college and made a little progress. After internship, my team spirit has been further sublimated.

In addition, through this internship, I have a better concept of time. I go to work at 8: 00 every morning and get off work at 1 1: 30, which improves my habit of sleeping late. During the internship, we drove at 7: 0015 every day, which also forced us to get up at 6: 00. At first, I complained a little, but later it gradually became a habit. Although some work is very tiring during the internship, hundreds of people go to North School by bus every morning after dinner, which takes about half an hour. Almost all of them work there, go to work at 2: 30 in the afternoon, get off work at 5: 30, and then come back by bus. Whether they go to work or take the bus, they all have a strong sense of time, otherwise they will suffer.

On the first day, I came to the North School by car with great joy, eager to satisfy my practical ability. The teacher called all of us to a small classroom to conduct safety knowledge and accident videos, and let me know that everything should be cautious. A small mistake may lead to an irreparable accident. The thrilling accident on the screen hit my heart hard. The teacher is right. No matter what you do, safety comes first. The monitor immediately took us to the computer room of industrial control work. I heard from the teacher at school that the intern teacher was very serious and strict. When we met the first intern teacher, we knew that the intern teacher was so humorous and kind. Then the teacher showed us the principle of gear shifting and the operation process of the robot, which made us fledgling calves eager to operate by ourselves. It went well, and each of us got what we wanted. But it let me know that many seemingly simple things, if really operated, will still encounter many obstacles, which requires our patience and keen observation. In this environment, our first day is coming to an end, and then the teacher gave us a fatal question, and whoever answers correctly will get extra points. The atmosphere is so high that students are anxious to answer whether they know or not. It can be said that extra points are king, and the first day is happy, but relatively speaking,

The next day, our internship was casting. It's a little scary to hear this name. Later, I walked into the factory where I worked, and all I saw was sand. I was curious about what it was. While I was still calm in this curiosity, a funny teacher came in and flew out a lot of Cantonese. God, let me listen to the fog. The follow-up teacher told us that today's task is homework, teacher. . . This casting is to make a model. After an honest explanation, the students find their own team members and do their homework. Two other boys and I flexibly poured sand into the wooden frame and hammered it with sticks and other things. Soon, we made a model and used it to make sandwich cookies. Ha, ha, ha. Finally, our group got an A, and then our whole body was weak and our limbs were sore. This shows how fragile college students are.

2020 metalworking practice report 1500 words (2) The two-week metalworking practice is over. Just like military training, there are unspeakable hardships and unforgettable happiness. I started classes this week, and I didn't feel tired of practicing during the day, but it's hard to avoid a special aftertaste when I watched the students majoring in mechanical and electrical engineering go to practice as we did two weeks ago. With the patient and meticulous teaching of teachers and our active cooperation, we didn't have an injury accident, basically reached the expected practice requirements, and successfully completed the two-week practice. Metalworking Practice is a highly practical technical basic course, and it is also an important compulsory course for engineering students in colleges and universities to learn the basic process methods and technologies of mechanical manufacturing and complete the basic engineering training. Not only did we gain the basic knowledge of mechanical manufacturing, understand the general operation of mechanical manufacturing, and improve the operation skills and hands-on ability, but also strengthened the exercise of integrating theory with practice, improved the engineering practice ability and cultivated the engineering quality. I learned a lot through this short and substantial internship.

Probably most science and engineering students in schools have to do metalworking practice. As a student majoring in assembly and control, it is natural to exercise in this process, but I didn't expect it to come so quickly and suddenly. I thought we were going to have classes according to the intensive homework schedule. I didn't expect that the first class in school was metalworking practice, which was both surprising and scary. Surprisingly, the legendary metalworking practice finally came to us, and its arrival greatly satisfied our curiosity. On the other hand, I am afraid because I don't know what the internship is like and whether it will be as dirty and tired as the legend.

Knowing that we were going to metalworking practice, we all took out the "pressure box treasure"-military training clothes, which became our preferred "work clothes" because of their dirt resistance and wear resistance. On Monday of the first week, early in the morning, we all wore white military training uniforms and set off for the metalworking practice factory behind the third district. Along the way, we also saw many people wearing the same clothes as us, and everyone walked to the factory in unison, which made me seem to have returned to my military training life last semester. We learned from the teacher that the internship lasted for two weeks. During these two weeks, we must learn locksmith and machining. In the first week, we must learn from locksmiths. The teacher called all the students at the gate of the factory, made some introductions, and then asked us to move chairs and sit down at the door. Then we put a message about the locksmith. The film is quite old. I can see that it has been a few years. The most important thing is that there are no subtitles. They are all outside the door. We have no contact with mechanical equipment and no subtitles, which undoubtedly increases the difficulty for us to understand and know the fitter. Fortunately, in the next few days, the teacher's explanation was in place, and when we went back and forth to the dormitory, we had a thorough and intuitive understanding of the fitter. The locksmith is a manual operation in cutting, mechanical assembly and repair operations, so it is named because it often clamps the workpiece with a vice. Fitter has a wide range of applications. The fitter's main task is to process parts. Some processes that are not suitable or cannot be solved by mechanical methods can be completed by fitters, such as marking, precision machining, inspection and repair. In addition, locksmith has applications in assembly, equipment maintenance, tool manufacturing and repair, which shows that locksmith is closely related to our life and production, so it is necessary for a science and engineering student to practice and contact locksmith. In the video and the teacher's explanation, we also learned that locksmith is the oldest metalworking technology in machinery. It has a long history. Although the development and popularization of various machine tools have gradually realized the mechanization and automation of most locksmith operations, locksmith is still a basic technology widely used in mechanical manufacturing. The fitter's work mainly includes chiseling, filing, sawing, scribing, drilling, reaming, tapping and tapping, grinding, straightening, bending and riveting.

With our preliminary understanding of locksmiths, the next step is the actual operation. You know, there can be no theory without practice. So, under the guidance of the teacher, a large group of us entered the factory, and there were many long tables, each with four working tables on both sides, and the tables were separated by barbed wire to prevent iron chips from flying out and hurting people on the opposite working tables during processing operations. In fact, a vice is installed on the workbench, and the one at the bottom of the table has a toolbox. The teacher asked us to find our own workbench, and then opened the toolbox to check whether the tools in it were lost or damaged. When I opened the drawer, I saw a lot of black things, horizontal and vertical, round and flat, and most of them didn't look familiar. Fortunately, there is a list of tools in it, and I can identify them one by one according to their characteristics. Our task is simple, that is, to process a circular iron column into a hexagonal nut. Because fitters are mostly operated by hand, we are struggling at first without training, and our hands are almost broken, but we are constantly familiar with it during tempering and know how to use tools correctly. Due to the revision of the operation method, we gradually became less struggling. On the fourth day, the nuts in my hand were shaped, at least in my opinion, they were finished. The completion of nuts is an encouragement to my efforts these days. Because I saw my finished products in the factory for the first time in my life, I felt very fulfilled.

Because of the rapid adaptation, time slipped away unconsciously, and the week-long locksmith internship quickly passed. Then the machining practice. Compared with the fitter, the "monster" at the processing end makes our curiosity explode instantly, but at the same time, the danger at the processing end is much greater than that at the fitter end, because those cold guys have no feelings and their strength is beyond our comparison. In fact, the whole metalworking practice, whether it is fitter or machining, teachers have been emphasizing safety issues. "Safe production and civilized construction" often echoes in our ears, reminding us to pay attention to safety. Because it is an operating machine, it is much easier to process here than the fitter, but at the same time, the processing accuracy of parts here is much higher than that of the fitter. We are a little distracted, either because there are too many cars or the cars are eccentric, which makes us very headache. The basic operation of lathe includes the clamping of workpiece, the selection of cutter, the change of spindle speed by shifting gears, and the mutual cooperation of left and right hands in cutting and feeding. There is an old saying: "Practice makes perfect". We cultivate the skills of operating lathes through repeated failures and repeated exercises. Our hands become very coordinated in the operation process, and we can flexibly adjust the rotation speed and control the feed. Finally, through our skilled technology and unremitting efforts, we create exquisite parts. In addition to lathes, we also contacted milling machines and planers, both of which are used to process planes. With the teacher's careful explanation, we have mastered the operation methods of these machines now. According to the teacher's words, this will be very helpful for our future employment, because now enterprises are not interested in what you are, but what you will do.

These days' practice has taught me a lot, and practice is an effective way to cultivate students' practical ability. It is also a very important and meaningful practical course for our college students and engineering students. Metalworking practice is another opportunity for us to actually master knowledge. Without a rigorous classroom environment, what we know is the production mode and technological process of modern machinery manufacturing, and what we feel is the atmosphere of the workshop. At the same time, we feel more about the significance of being a worker, which makes us more aware of our responsibilities. Although sometimes we are really tired and hard, our hands and feet are sore and we don't get enough sleep, these are actually exercising us and laying a solid foundation for us to adapt to work as soon as possible after going out. I feel that this metalworking internship is quite necessary for us, because everyone will come into contact with these machines more or less in the future. If we don't study today, we may have to pay a high price for studying in society in the future.

In practice, theory and practice are very important, and they should be combined. Sometimes, if you don't have a theory, but you can't find a chance to practice, then no one will recognize your ability, and even simple things should be practiced seriously. At the same time, sometimes we underestimate the theoretical knowledge too much, thinking that we can master it, thinking it is very simple, and the teacher didn't listen carefully when explaining the demonstration, so that we made mistakes from the beginning. So I think the two should be balanced and permeated with each other. In practice, our role is workers, so we should be more aware of our responsibilities. As workers, the most important thing is to abide by various rules and regulations and operate the machinery correctly under the premise of safety, so as to produce products that meet the standards. So in the process of internship, one word is very important, and that is safety. The fitter teacher said, "I didn't ask you to master all the fitter's skills in this week, which is impossible, but there is one thing that must be done, that is, safe production and civilized construction!" " Therefore, before construction, we must understand the safety issues that should be paid attention to in each type of work, such as not fooling around during operation, not tying long hair, not wearing slippers and so on. There are many safety requirements for various types of work. For example, locksmiths are allowed to wear gloves, but turners must not wear gloves.

There is also a very important attitude. Since you are a worker, you have to look like a worker. Attitude is everything. Attitude should be correct first. Every factory has its own rules and regulations. When you enter an enterprise, you must abide by their rules, such as the commuting system. Many students become old-fashioned on the first day of internship. They were late for work, ran away from work and completely ignored the internship. I am glad that the university has offered such a course for me.

Another thing I learned in my internship is the spirit of unity. In a small room, sometimes a machine needs a lot of people to operate, and we need to have enough tacit understanding, clear division of labor and coordination in production. In a big sense, everyone works in the same factory and should help each other. During the internship, students sincerely encourage each other to refuel and share the pressure of work and the joy brought by success. Metalworking practice is more like a collective activity, which has narrowed the distance between us and filled the gap that once existed. The charm of collectivism is vividly displayed!

2020 metalworking practice report 1500 words (3) metalworking practice is a compulsory and practical technical basic course for mechanical engineering students and an effective way to cultivate students' practical ability. As students of physics research, they don't need to have strong mechanical operation ability, but they also need to have certain learning ability and basic knowledge of common instruments, so as to get comprehensive and balanced development in social practice activities and lay a certain practical operation foundation for our science students.

In this five-day internship, students are required to be familiar with the basic process knowledge, basic process methods and basic operations of mechanical manufacturing through independent practice in metalworking practice, and initially understand and master various operating essentials of six types of jobs and the ability to independently manufacture simple parts. The internship arrangement corresponds to six types of work: foundry worker on the first morning, fitter in the afternoon, lathe worker on the second day, milling worker on the third day, CNC lathe worker on the fourth day and welder on the fifth day.

Fitter caster

The two jobs on the first day can be said to be the most tiring jobs. For college students who are only active in classrooms and dormitories at ordinary times and are only tired of playing ball games, casting and locksmith are not so simple. They need not only our physical strength but also our patience.

In the morning, foundry workers, our task is to stir the slightly wet sand and cast it into the mold with funnel needed by the steelmaking plant. First of all, the teacher explained to us a lot of basic knowledge of casting, as well as the connection and difference between casting and other types of work, as well as the safety matters that should be paid attention to in operation and the essentials of action that should be mastered when casting. Although it looks simple, listening to the teacher's explanation and watching the teacher demonstrate the operation doesn't seem to require many technical essentials, but it must not be sloppy. Every step needs to be done in strict accordance with the teacher's standards, especially the strength should be used in place, evenly and repeatedly to get the final mold. After more than an hour of fiddling, we all finished the task as required. Although we are tired and weak, we are still very happy to see our elaborate molds.

In the training of locksmiths, we know that the main contents of locksmiths are scraping, drilling, tapping, sawing, filing, assembling and marking; Understand the structure, classification, selection, filing posture, filing method and quality inspection of archives. First of all, we must get the right gear. It is the key to keep the file moving in a straight line when filing the plane. There are two kinds of filing force: horizontal thrust and vertical pressure. When pushing the file forward, the front hand pressure gradually decreases, and then it decreases when pushing the file to the middle position, and the pressure on both hands is the same. When pushing the file forward, the front hand pressure gradually decreases and then increases. No pressure is applied when the file is returned. This will make it easier for us to file. At the same time, I also know that the locksmith's safety technology is: 1, and the bench should be placed in a place where the work is convenient and the light is suitable; Drilling rigs and grinding wheels should generally be placed on the edge of the site to ensure safety. 2, the use of machine tools, tools (such as drilling machine, grinding wheel, hand drill, etc. ), should be checked regularly, found damaged shall not be used, need to repair the rear can use. 3. When the vise clamps the tool, it is not allowed to use a hammer to beat the handle or steel pipe of the vise to exert clamping force.

Then scrape, grind, drill, hinge, tap and so on. Although it is not very standard, it is the crystallization of our sweat and the result of our two-day struggle.

(the long process of giant iron)

To tell the truth, locksmith training is boring. He may have been doing an action repeatedly all morning, but he should be strong and do it just right. That is, a file that goes back and forth on the workpiece with a file. By noon, the whole person's hands were sore and his legs were stiff. However, when he is tired, he can see the teacher personally guiding and demonstrating. He is also sweating and panting. A few days later, looking at my own processing results, I want to say thank you to the teacher who guided us.

Lathe work

Lathe is a machine corresponding to lathe, which is mainly composed of gearbox, spindle box, change gear box, feed box, slide box, tool rest, tailstock, lathe bed, lead screw, polished rod and joystick. Lathe is operated by various handles. After understanding the function of each handle, the teacher showed us the machining process of a small part that needs to be completed today according to the requirements of the drawing, and gave guidance on the matters needing attention. A very important aspect in lathe machining is to choose the right turning tool. The lathe we used for this internship is equipped with three turning tools, of which the threaded tool does not need to be mastered. Our task is to process small parts with a big circle diameter of 20mm, a length of 5mm, a small circle diameter of 15mm and a length of10 mm. The meticulous operation requirements and detailed data calculation and analysis are all severe tests for students who have never worked as actual workshop workers. It is precisely because of my lack of experience and patience that I cut the length of the great circle of the parts into 4mm in the last step of parts processing. I am very sad. It can be seen that although the lathe worker is not so tired, it is a delicate job, which requires a high degree of concentration and high technical requirements.

moth

There are many practical things in this kind of work. In the morning, the teacher explained the types, standard specifications, operation specifications and essentials of milling machines, as well as safety precautions, and demonstrated the "milling" process of workpieces with grooves and protrusions required by the drawings. The next step is for us to do the actual operation in groups. All morning, we were cutting the workpiece on the machine tool, aiming at the target, aligning the knife, calculating the size, and cutting again and again to complete a workpiece. However, because it is the first processing, I dare not be careless, so the first workpiece cutting is relatively flat and the dimensional error is small. In the afternoon, we were much more skilled in operation and calculation, so we divided the operation, one person calculated and cleaned the iron filings, and the other two people controlled the handles that moved up and down, back and forth, left and right, and cooperated with each other to quickly complete the processing of the remaining two workpieces. Although I feel very tired, I am deeply impressed by the high demand for machining accuracy in mechanical processing. I realize that doing "rough work" of machinery requires not only a fairly high technical level, but also strict requirements for the care and patience of workers.

Cnc lathe

CNC lathe can be said to be the easiest job. However, a seemingly simple job has a good technical content. Workers should not only be able to operate digital equipment, but also understand the meaning of digital symbols, and write programs for CNC lathes, that is, they should be able to input codes to control the direction, speed and transformation of turning tools as required. Through the operation and programming of CNC lathe, I deeply felt the convenience, accuracy and quickness of CNC. As long as the correct program is input, the lathe will perform the corresponding operation. The programming requirements of car counting are very high, and a wrong symbol may lead to the failure of car counting. But programming is not very difficult for me, and the programming instructions are also explained in detail. Soon, according to the teacher's request, I compiled a program for cutting threads with the required depth and length, and successfully ran it in the computer simulation CNC lathe program.

weld

On the last day, I learned gas cutting and arc welding. Gas cutting is similar to welding, but there are still differences. Manual gas cutting operation is to deeply understand the process and basic principle of oxygen cutting. Pay attention to whether the workpiece metal has melted and whether the incision is narrow and uniform during the whole gas cutting process. We observed and learned the process of manual gas cutting of low carbon steel by the teacher. Firstly, the metal is preheated, and then the cutting oxygen (pure oxygen) airflow is put in, so that the steel plate immediately forms a narrow and neat cut, and then the gas cutting muzzle moves straight along the cut to form a neat cut. The requirements of gas cutting are also very high. The gas cutting should be straight and the flame should be adjusted well, otherwise it is difficult to cut the workpiece, and the flame should not be too large to cause fuel waste. In the process of gas cutting, the muzzle should not be pressed too low to prevent tempering, and the distance between the muzzle and the workpiece should be controlled at about 5 mm. Once tempering, the liquid acetylene (the nearest gas valve) should be closed immediately, and then the other two gas valves should be closed. Don't ignite the gun until it cools down. After half a day's gas cutting practice, each of us cut an iron plate by hand. Although some cutting is uneven, we finally successfully completed the task and mastered the technical essentials of gas cutting.

In the afternoon, we learned arc welding under the guidance of our teacher. The teacher first introduced us to several common arc welding, as well as the operating precautions, operating essentials and specifications during welding, and then explained in detail how to weld and how to use covered electrode, so as to let us know the common welding methods (manual arc welding, automatic submerged arc welding, gas welding, etc. ), equipment and materials used, common welding defects and welding deformation. Through the teacher's explanation, we know the connection of power grid, circuit breaker (switch), electric welding machine, electrode holder, covered electrode, arc, workpiece, weld and other lines, understand the composition and function of welding covered electrode, the types of covered electrode and covered electrode specification (covered electrode diameter), four common joint types and four common groove types of butt joint, and the dimensional parameters and functions of groove, butt joint, fillet welding and multi-layer multi-pass welding. What we mainly master is friction arc initiation. Our task is to weld 5-6 covered electrode with uniform width on a steel plate. After half a day of arc welding practice, we haven't fully mastered arc welding, but we have also learned a lot of basic operations of arc welding.

Leaving the environment of classroom theory, we feel the meticulous and rigorous atmosphere in the workshop. Through this metalworking practice, we have basically understood various matters that machine tool workers need to pay attention to, mastered the operating norms and skills required by these six types of work as required, and all have the ability to independently modify or process simple small parts. But more importantly, we learned how to accept and master a new engineering technology, how to adapt to the new environment, how to master the operation of new machines, and how to cooperate with colleagues to complete tasks. I think this is the most important harvest of my metalworking internship. I believe this will be of great help to our future entry into society and entrepreneurship.

The short five-day metalworking practice life is over, and our metalworking practice has also come to a satisfactory end. We thank the school for providing us with such an opportunity, and we also deeply thank our teachers. Their words and deeds have benefited us a lot. I didn't know anything from the beginning, but now I have a deep understanding of various machines and mastered some basic operations. This metalworking practice is unforgettable.

Metalworking practice brings us not only the operational skills we are exposed to, but also the ability we need to exercise through several types of work. More importantly, we need each of us to feel, reflect, encourage ourselves diligently and gain something after the internship, so that this internship can achieve the real purpose.

2020 metalworking training report 1500 words (4) Since I entered the company's welder industry, I have always been conscientious and diligent in this ordinary position, not saying much, obeying distribution, being diligent and eager to learn, mastering excellent welding technology, and being familiar with the sheet metal technology and skills commonly used in steel structure production and processing. Under the careful care and guidance of leaders and colleagues, through myself, I now report my work as follows:

In terms of work, there is a famous saying that "to do a line, you have to love a line". Based on this idea, I devoted myself to the work of electric welder. In order to do a good job and improve my professional level, I humbly learn from the company leaders and predecessors engaged in this industry, learn from their strengths and make up for their shortcomings, and then explore the practice myself, gradually get familiar with and understand the basic essentials of electric welding, clarify the procedures and direction of work, and constantly improve my working ability, which is formed in specific work.

Moreover, I have a correct attitude in my work, stick to my post, be serious and responsible, help other colleagues to complete their tasks while completing my own tasks, love my job, treat every job correctly and seriously, devote myself to my work, serve everyone enthusiastically, seriously abide by labor discipline, ensure attendance on time, make effective use of working hours, and need to work overtime on time to ensure that the work can be completed on time, with high quality and efficiency, and work for the company and departments.

Finally, the work over the years is summarized, and the achievements and progress are obvious to all. However, there are still some areas that need to be improved, such as insufficient arrangement of materials in construction. Often after this incident, people are looking for the materials they need for the next step, so they miss a lot of working time. For this reason, I took the time to cultivate my carefulness and achieved certain results. I believe this problem will be removed soon.

Looking forward to the future, in my future work, I will strive to improve my own quality, overcome my own shortcomings, and work in the following directions:

1, learning is endless, the times are developing with each passing day, and the knowledge of various disciplines is changing with each passing day. I will persistently learn all kinds of welding related knowledge and use it to guide practice.

2. "Indulge in diligence and neglect leisure", constantly learn business knowledge in the future work, and constantly improve your business skills through more reading, learning and practice, so as to achieve scientific management, standardized operation and mechanized construction.

3, constantly exercise their courage and perseverance, improve their ability to solve practical problems, and slowly overcome impatience in the process of work, positive, enthusiastic and meticulous treatment of every job.

4. Actively promote and apply "new science, new technology, new technology and new materials".
