Man: a person who participates in making model ships. You should master the basic knowledge and skills of process management, computer CAD drawing, process processing, mechanical power, electrician and electronics, material application, coating and bonding, modeling and carving, text expression, cost accounting and so on. This is usually achieved through the quality structure and combination of ship model team (studio) personnel.
Machine: there are special equipment and tools for making ship models. This is an important means to solve the production difficulties and ensure the technical level of the works. From a certain point of view, exquisite works are the expression of craftsmanship and tool ability. In general, it should be appropriate and completed step by step.
Material: the material for making the ship model. Modern ship model materials are widely used and can give full play to your creativity. But the four principles of material selection are still: low cost, easy processing, high quality and strong texture simulation. Today, wood is still the basic material for making ship models. For example, in the rowing model, in order to improve the speed as much as possible, the light phoenix tree is often used to make the hull structure; For the self-propelled ship model, in order to reflect the appearance of the hull surface, Korean pine or ginkgo wood with good bending performance and processability is often selected; In order to improve the collection value and fully display the simple and elegant artistic culture in Europe and America, precious wood with stable wood, uniform and pure color and delicate texture is often used to make hulls and decorative sculptures, in pursuit of the beauty and collection of works.
Ring: the environment for making ship models. Whether the layout of the ship model studio or the ship model workbench is reasonable and ingenious directly affects the effect of ship model making. Under normal circumstances, it should be appropriate for the place, people and things. The basic principles to be followed are: convenient and comfortable work, fixed goods placement and convenient external contact. Specific equipment and facilities, as far as possible: data storage cabinet; Work display cabinet; A workbench equipped with necessary equipment and tools; Water, electricity, lighting, air conditioning, computer, telephone, dust removal facilities; Fire emergency measures, etc.
Methods: Management methods of ship model making. With the mature application of modern management science. Modern ship model making, whether amateur or professional, pays great attention to process management. In foreign countries, before making high-quality ship models, it is necessary to standardize the Guide to Ship Model Making and strengthen the process management of ship model making. The basic contents of "Guide to Ship Model Making" consist of ten items, such as revision of production level, plans and budgets of production projects, drawings and materials, plans of materials and accessories, production process sheets, man-hour schedules, test records, external liaison memos, expense diaries and publicity documents of works. The Guide to Ship Model Making is very necessary for ship model makers to make works, participate in competitions and conduct business negotiations.
1. Set the drawing or template with 1: 1 according to the appearance of the photo. Generally, the main deck, bottom profile plate and stern plate are needed.
2. Fix three plates on the flat glass as the basic outline of the hull.
3. Mix the paraffin vaseline and talcum powder according to the ratio of 1: 1: 3, the paraffin has more sludge, and the manufactured mold has high hardness and smoothness, and the vaseline has more sludge and is soft.
Easy to make. There is no absolute requirement for the proportion, which can be determined according to your own preferences.
4. Heating, mixing and melting the prepared raw materials. Generally, do not heat directly on the fire, which is easy to burn. You can take a large pot and a small pot to heat it from the water. 5. Make an outline according to the hull with plastic foam and plywood sludge. At this point, the hull is very rough. Clay sculpture can't be done at one time, it can be pasted many times.
6. After the outline of the hull is completed, paste the mud on it. This process is similar to sculpture. Clay sculpture can't be done at one time, it can be pasted many times.
7. Finishing is similar to sculpture, which requires skill and patience.
8. Make an outline according to the hull with plastic foam and plywood sludge. At this point, the hull is very rough. Clay sculpture can't be done at one time, it can be pasted many times.
After the mud paste is completed, rough machining, scraping with a knife and planing with a model plane are started to process the basic shape.
9. Use homemade small iron and oil painting knife to flatten it, and flatten it with oil painting knife. This process will also leave hot marks after processing, and then use sharp artists.
Scrape the blade on it and you will see satisfactory results.
10. Iron it with homemade small iron and oil painting knife, and flatten it with oil painting knife. This process will also leave hot marks after processing, and then use sharp artists.
Scrape the blade on it and you will see satisfactory results.
1 1. Basic molding
12. Dressing tool
13. The male die after finishing.
14. Before gypsum pouring, wax the surface of the male mold with floor wax, and repeat for 3-4 times. The brighter the surface, the better, which is convenient for demoulding.
15. Use medical medium anhydrite instead of super anhydrite, because the initial setting time of medium anhydrite is moderate.
16. Wrap the mold with plywood.
17. The ratio of gypsum to water is 1: 1. The proportion of water should be appropriately reduced in winter and increased in summer. Gypsum and water should be stirred quickly and the time should be controlled.
Within one minute, the gypsum-like viscous liquid can be poured into the mold with a ladle, and the pouring sequence is around the center, so the pouring is rapid.
Gypsum will set over time. After gypsum pouring is completed, the surrounding gypsum can be properly piled in the middle with a putty knife, just like the shape of the bottom of the ship.
18. After gypsum pouring is completed, the surrounding gypsum can be properly piled in the middle with a putty knife, just like the shape of the bottom of the ship.
19. The demoulding time is generally 20-30 minutes after pouring, when the gypsum is slightly hot.
20. Generally, 20-30 minutes after casting, when the gypsum is slightly hot. When the mold is lifted, the bottom of the hull is laid flat on a soft cushion, such as a sofa and hands.
Gently lift the glass around, and when you see that the gypsum around can be separated from paraffin, lift the glass as a whole. If the separation is good, paraffin will be used.
The male model is still intact.
2 1. After the hull female die is completely dried, it can be made into FRP. First, wax the female die surface of the dry hull for 3-4 times. Secondly, choose the appropriate weather.
Generally speaking, the climate is dry, and summer above 30 degrees is more suitable. If you have an oven, it is another matter, and then choose epoxy resin and glass fiber cloth.
22. Fine glass cloth should be tightly woven and soft.
23. Blend epoxy resin+dibutyl ester (plasticizer)+ethylenediamine (curing agent) according to the ratio of100:12-20: 8-12, with one layer of epoxy resin and one layer of glass.
Glass cloth, 3-4 floors at the bottom and 2-3 floors at the ship's surface. The thickness of the cast hull is about 2MM. Exposure to strong sunlight for 4-6 hours after dumping, or
Heating and curing in an oven at 65438 000 degrees for 2-4 hours.
24. After pouring, expose to the sun for 4-6 hours, or heat and cure in an oven at 100 degree for 2-4 hours. Then demoulding and trimming the FRP,
The upper and lower parts are connected together.
I hope to adopt it after I finish it.
This may be a bit difficult.
