With the development of society and economy and the progress of industry, sheet metal parts are used more and more widely in our daily production and life. All kinds of sheet metal parts are used in automobiles, machine tools, and various household appliances. Therefore, how to make sheet metal products with good quality and beautiful appearance is particularly important. Every link in the sheet metal fabrication process is very important. Problems in any link will affect the fabrication quality of the product. Therefore, the accuracy of each process must be ensured. Only in this way can a sheet metal product with beautiful appearance and qualified quality be produced. So, in the design of sheet metal products, what matters should be paid attention to in the fabrication of automotive sheet metal parts?
The sheet metal fabrication process mainly includes CNC programming blanking, bending, riveting, welding, spraying, packaging and other processes. The process of sheet metal fabrication is a combination of theory and practice, and it is a production process that organically combines basic process knowledge, basic process methods and basic process practices related to mechanical manufacturing. In this process, pay attention to the following aspects: when using the sample drawings, the unfolding method should be convenient to save materials and the timeliness of fabrication; the position and direction of pressure riveting, budding, punching points (packages) should be marked in the cross-sectional view, so as to facilitate the Machining can also be understood more intuitively; parameters such as plate thickness, material and plate thickness tolerance should be checked, and key points should be marked for error-prone places; for larger and more complex places, this part of the figure should be enlarged. ; Tips should also be made for products that need to be painted or protected. In short, in the process of sheet metal fabrication, it must be completed in strict accordance with the fabrication procedures.
It should be noted that the post-fabrication of sheet metal products is mainly the treatment of the surface of sheet metal products, that is, in order to protect the parts, a layer of film is applied to the surface to prevent oxidation, and it can also enhance the adhesion of baking paint. The process includes Electroplating, electrostatic adsorption, paint baking, oxidation treatment, etc. Among them, electrostatic adsorption is mainly used for cold-rolled sheets. The sheet metal parts are basically finished after post-fabrication. Therefore, we must pay attention to the protection of the material parts and not scratch and bruise them, otherwise they will not be qualified.
Whether it is the car shell, the protective cover of the CNC machine tool, or the computer case, the communication equipment and other products are inseparable from the sheet metal, and as the sheet metal fabrication technology becomes more and more mature, the sheet metal shows a broader development prospect. However, sheet metal fabrication is a relatively complex work, involving not only various process methods and parameters, but also equipment principles and operating techniques. In sheet metal product design, as a designer of a professional industrial design company, it is necessary to discuss sheet metal design, fabrication procedures and precautions to ensure the quality of sheet metal products.
