Summary of fitter's practice in No.1 factory

Some people may not understand that locksmiths are metalworking professionals, so what does that have to do with molds? Mold is a kind of production tool, which can produce parts with certain shape and size requirements. First, mold designer designs the mold structure according to the use requirements of products (parts) and draws the drawings. Then, technicians make each part on the mold through various mechanical processing (such as computer gong, lathe, planer, milling machine, grinder, EDM, wire cutting and engraving machine) according to the requirements of the drawings, and then assemble and debug it until qualified products can be produced. This factory is very profitable. Bench fitter is an essential process for making molds.

Metalworking students go to the factory for internship, which means that the school gives students an opportunity to practice and study. At school, teachers talk about work theory, and there are few opportunities for practice. Moreover, work experience can not be obtained by theory alone. Only by doing it yourself can we know where we are doing well and where we need to improve. My internship workshop is a die fitter, and there are many machines in the workshop, so before entering the workshop, some people will emphasize work safety, such as; Before going to work, don't drink, don't wear slippers and high heels, and don't play and laugh. Don't touch electricity with wet hands, and don't touch the three incoming wires above the air switch. As a fitter, his basic operation is;

1, marking, is the operation of marking the machining boundary on the blank or semi-finished workpiece according to the pattern.

2. Cutting operations, including chiseling, sawing, filing, tapping, tapping, drilling (reaming and reaming), scraping and grinding.

3. Assembly operation, that is, assembly, is the process of assembling parts or components into machines according to the technical requirements of drawings. This is the basic work of a locksmith, and it is indispensable in the mold making process. When I started my internship, there was always a senior or tutor around me. For example, when I submitted the document, they said: Don't touch the working surface with your hands to avoid slipping and injury, and don't blow iron filings with your mouth to avoid flying into your eyes and injury. He also said that we should not use the grinder without authorization. If we want to use it, we can operate it under the guidance of the teacher. People should stand on the side, work must be clamped firmly, and the force should not be too great. Wait a minute, although it's troublesome and verbose, those predecessors are all good for us. If there is an accident, it will be too late to regret it. The beginning and end of the internship. After the internship, the instructor asked us to put the tools in order, put the tools and measuring tools in order, do a good job in hygiene and develop good work habits.

The internship time is not long, but it helps us interns a lot. We have a deeper understanding of metalworking. Finding problems is the beginning of solving them. If you don't understand, consult a technician or find information. By learning from teachers and books, we will eventually solve one problem after another. Through this internship, I know my own shortcomings, and I will work harder to make up for them in the future. After internship, I have improved our social practice ability and communication ability. Make yourself full of confidence in your future work. In the future study and work, I will work harder and strive for better.

Summary of fitter's practice in No.2 Factory

20xx65438+started working in the factory in February, and joined the China Party in February. After four years' study from 20XX to 20XX, I obtained a college diploma in thermal energy engineering. I have been engaged in this major 16 years, and now I am a fitter in the maintenance workshop of thermal power plant, and I am recruiting the third professional and technical leader of the group company.

Professional ethics: support the leadership of the party, love the enterprise, have good professional ethics, be diligent and willing to study, and win the appreciation of colleagues. I have been able to do my job conscientiously since I entered the factory 16 years ago. He has been rated as an advanced individual at the factory level and an excellent team leader at the company level for 8 times, and has also been rated as one of the top ten civilized employees of Juhua Group in 20XX. In 20XX, he won the first prize in the fitter technical competition of the group company and participated in the first national conference held in Shenyang in? Zhenxing cup? Skills competition for young workers. It is a rare opportunity to participate in the national competition. In order to get good grades in the national competition, I stood by the vise for practical training for eight hours during the day, made test boards one by one, did all the questions I could think of several times, and went home to study various professional books at night. In the end, it won the tenth place in the group in the fierce competition of nearly 100 strong teams in the country. In 20XX, I was rated as an expert in Zhejiang's youth work. In the same year, he obtained the qualification of national professional skill appraisal firm; In 20XX, he won the second place in the fitter technical competition of group company and the fifth place in the fitter competition of provincial enterprises. 20XX 10 obtained the fitter technician certificate with good results. Participate in 20XX years? South China Cup? The national chemical fitter technical competition won the third prize of individual and the tenth place of the group. At the same time, through four years of correspondence study, I obtained Shanghai Electric Power University? Is it hot? Professional college diploma, personal theoretical knowledge level and practical operation skills continue to improve. Although I have made some achievements in my work, I dare not slack off in my work. Over the years, I have been trying to use my knowledge and skills to contribute to the enterprise and play my role. As a skill leader of workers in Juhua Group, I not only participated in technical learning activities myself, but also strengthened technical training for young workers. I think I'm good at it. More importantly? Belt? Produce new technical experts to make the work of enterprises better. Through several years' self-cultivation, the team has formed a good atmosphere of learning technology and attaching importance to skills, trained a group of young workers with excellent work skills, and provided a strong talent guarantee for the smooth development of the team's production work. The young workers in the class have obtained intermediate vocational and technical grade certificates, some have obtained advanced vocational and technical grade certificates, and many young workers have achieved good results in technical competitions at the factory level and group companies.

Making skills: As a locksmith, I have a persistent pursuit of learning skills, which makes me never stop, and I am not afraid of the pain of sawing, filing, grinding and measuring when locksmiths practice training. I attach great importance to technology accumulation in my daily work. I always carefully analyze the problems encountered in my work, keep them in mind bit by bit, practice whenever I have the opportunity, use the skills I have learned many times to solve practical work problems for the factory, actively put forward reasonable suggestions and participate in technical transformation. Drilling holes in the thin plate of #6 boiler reconstruction site is an example of combining sub-theory with practice. In the DCS reconstruction project of #6 boiler in thermal power plant, there are more than 100 field control panels drilling button holes from the zero-meter floor of turbine and boiler to the top of more than 40 meters high, and the factory department requires to complete the drilling and installation task within one week. Using the old method to drill holes first, and then using a file to round the holes, not only the working speed is slow, but also the labor intensity is high and the quality cannot be guaranteed. Combined with practical experience and theoretical knowledge, I tried a new method of drilling holes with thin-plate hand electric drill on the spot. I found an old drill, made a very thin drill myself, and processed it into a small tail straight handle that is easy to clamp with a hand electric drill. The experiment succeeded in one fell swoop. This method saves time and labor, and the work efficiency is improved by nearly 20 times. The test method also won the company's excellent rationalization proposal award. The success of the first exhibition made me more addicted to the study of fitter technology. In recent years, the technical transformation of the muffler of the steam heater of central air conditioning has been completed; Modification of gear lubrication system of 40-meter gantry crane bridge: methods to prevent electric hoist from winding rope, etc. During the overhaul of #8 boiler this year, four of the eight fixing screws for fixing the spiral sleeve of the ball mushroom machine at the outlet of #8 boiler were broken in the spiral hole of the journal. The maintenance personnel spent several days and tried various methods, but failed to take them out. If we want to replace the new spiral sleeve, it will not only be a heavy workload, but also increase the maintenance cost of nearly 10 thousand yuan. I accepted this problem, and it took me only half a day to take out the four broken big screws on the journal, which not only saved the maintenance cost, but also ensured the maintenance progress. Through the solution of technical problems, I not only learned advanced technology, but also further improved my skills, realized the progress of maintenance technology and better served the production of enterprises.

Work performance: For many years, as a monitor, I arrived at my post half an hour in advance every day, inspected the equipment in my post, kept abreast of the operation of the equipment under my jurisdiction, made reasonable arrangements for my daily work, ensured the safe and stable operation of the equipment under my jurisdiction, and was able to complete all kinds of maintenance and technical renovation work arranged by the factory department with a rigorous, realistic and serious working spirit. During the operation of the economizer tube of boiler No.7 in a thermal power plant, the upper part of the economizer tube appeared local wear. If it continues to be used, it may cause economizer tube explosion accident during the next overhaul. If all the economizer tubes are replaced, the overhaul cost will increase1500,000, and the economizer tubes will be cut off and turned over 180? After continuous use, the economizer tube can be used for another overhaul cycle. However, it is very difficult for 148 row of 250 kg economizer tubes to turn over in a narrow flue. In order to complete the arduous task assigned by the factory department, I took the team's maintenance personnel to work hard and operate skillfully on site, setting the fastest speed for installing 8 rows a day, and completed the turn-over of economizer tubes one week ahead of schedule. #9 boiler deaerator maintenance work, I took you to complete the deaerator ontology and more than 60 valves maintenance, and successful trial operation. Completed the selection and installation of central air conditioner in the central control room of thermal power plant. Half a month before the Spring Festival last year, the reconstruction project of a large-caliber water supply pipe with a water treatment post of 200 meters long and a water supply capacity of 600 tons/hour was completed. In 2007, the technical transformation and installation of three 200t/h intermediate pumps were completed. In the first overhaul of boiler #9 in thermal power plant, the overhaul of transverse low-pressure heater # 1 of boiler #9 was the first problem encountered, because the original five units of thermal power plant only had vertically installed low-pressure heaters, such as this one, which is 5 meters long and weighs 7 tons, lying under the belly of the steam turbine. This is the first time that a coal-fired power plant has encountered it. The workshop assigned me this job. In order to complete this overhaul safely and smoothly, I made a detailed overhaul plan and safety measures before the overhaul, and made reasonable and effective improvements according to the actual situation during the overhaul, so that the whole overhaul process of #9 unit # 1 transverse low-pressure heater was completely within the pre-control range, and the overhaul work was successfully completed and the trial operation was successful.

Teaching technology: In addition to completing the main tasks, I combine my years of study and experience, combine team work with teaching technology, improve the practical ability of team members to solve work failures, and guide class members to carry out technical training in the daily technical training of the team. From the actual production of hexagon, cross, dovetail groove and other accessories to the face-to-face study of professional technology theory, through a series of technical training, the young workers in the class have obtained the technical grade certificate above the intermediate level, which effectively improves the overall technical quality of the locksmith class. According to my own professional expertise, I also held two professional technical lectures for young workers in the factory, namely "Processing technology of typical parts" and "Grinding method and key points of standard group drilling", to briefly introduce their daily work to young workers.

Technical innovation: Locksmith is an ordinary job. In the continuous practice and innovation of all walks of life, all kinds of advanced technologies are always emerging one after another. In his usual work, he often encounters various problems, such as the loud noise of the steam heater of the central air conditioner in our factory, the dry grinding of the gantry crane bridge gear and the low output of the lithium bromide unit. By analyzing the causes of each problem, I put forward solutions, put forward reasonable suggestions to the workshop and implement them, which further improved my practical working ability. If you don't understand, ask a technician or find information. By learning from teachers and books, you can finally solve one problem after another.

? A flower does not represent a spring. ? As the professional technical director of Juhua Group, I will continue to do my job well in my post, and at the same time, I will continue to do my best to help the young employees of the enterprise in order to greatly improve their technical skills and better serve the enterprise. Make your due contribution to the future of our company.

Summary of fitter's practice in No.3 Factory

In a blink of an eye, the two-week locksmith internship is coming to an end. Looking back on the past two weeks, I have sweated, failed, hurt and laughed. It is these colorful fragments of life that have become an indispensable part of my life and left me with beautiful memories.

On the first day of internship, we trained lathe workers. It's my first time to contact this kind of work. I am not skilled, especially prone to mistakes, and I still work standing up. At the end of the day, the whole person has a strong sense of collapse. From curiosity at first to boredom later, it is only a short process. But it's really a sense of accomplishment to see a smooth and clean workpiece come out of your own hands.

A long time ago, I heard from my brothers and sisters that fitter practice is the hardest. I haven't experienced it personally before, so I haven't felt anything yet. I have experienced it personally this time, and I have to admit the hard work of the fitter. The fitter is almost entirely operated by hand, which requires high technical skills of workers, and in order to work, he has to stand and process. Although there is an air conditioner or an electric fan in the operating room, we often sweat after work. One sweat hasn't gone down yet, and the other one comes out again. Some students sweat like rain on the workpiece, which is particularly hard. Looking at the small hammer made by himself, Xiao Qizi is not perfect, but he is still very pleased. I used to think that everything around me was nothing, so I got used to it. But now I find that the original simple things also contain a lot of wisdom and hard work.

After the internship as a lathe worker, I was exposed to special processing. Through the practice of special processing, we learned several advanced processing technologies, and personally operated or participated in the design and processing of specimens, and produced many exquisite workpieces, which were accepted by us as souvenirs and became permanent memories.

I just saw the workers in the factory welding when I was a child. At that time, I was told by adults not to look at the welding arc, so I was always afraid of welding. But I didn't expect this internship to include welding. At first, I was afraid of electric welding. I didn't dare to ignite or arc. Under the guidance and guidance of the master, I gradually eliminated this kind of emotion and gradually adapted to the working environment and way. Although the final result is ugly, it also witnessed the process of self-defeating, although ugly but proud.

The content of the final internship is casting, which is much more interesting than before. Every time I get a model, I think about how to fractal it, and then make a sand shape and cast it. The first day was all practice, and about four models were cast. I have basically mastered the methods and essentials of making sand shapes. Looking at the complete and smooth sand mold after the parts are taken out, it seems to uncover the mystery of a long-awaited problem. Casting practice, although very tired, is very interesting. Forget fatigue when working, and gain not only knowledge, but also happiness.

In a word, through two weeks' practice as a locksmith, I broadened my horizons and gained some knowledge that I can't get at ordinary times. Locksmiths can greatly exercise a person's toughness, perseverance and carefulness. If any detail is not handled properly, all previous efforts will be wasted. So I have benefited a lot from this practice.
