Sheet metal equipment is widely used in our lives, such as common computer cases, power cabinets, self-service terminals, CNC machine tools, and so on. Due to the special properties of sheet metal parts, sheet metal processing has a greater impact on sheet metal design. Therefore, in the process of designing sheet metal parts, it is necessary to fully consider the influence of the sheet metal material process and highlight its characteristics and advantages. So, what are the characteristics and advantages of sheet metal design?
First of all, we need to understand what is the gold? The remarkable feature of sheet metal is that the thickness of the same part is consistent. By definition, sheet metal is a cold work process for metal sheets, including shearing, punching/cutting/compositing, folding, riveting, splicing, and forming (such as automobile bodies). The surface treatment of sheet metal parts is mainly in two major ways: spray (dusting) and injection. Large pieces are usually sprayed, and small pieces can be sprayed. This is determined by the characteristics of the process.
Compared with other cutting processes, sheet metal parts processing and cutting technology has high speed, high precision and high adaptability, small slits, small heat affected zone (small deformation), good cutting end face quality, no noise cutting, weld seam The advantages of block and performance are close to that of the base metal; and the processing requires only simple fixtures and no mold, and can replace the processing method using complicated die punching, which can greatly shorten the production cycle and reduce the production cost.
It should be noted that the structural design of the sheet metal part mainly serves three functions. One is the load-bearing part of the equipment, which needs to bear the gravity of the main body (including the force generated during the movement); the second is the movable connecting part of the equipment, which needs Coordination and consistent operation according to the requirements of the application software; Third, the external framework of the main body needs to reflect the characteristics of flexible hardware. Therefore, sheet metal equipment needs to be integrated with materials science, mechanics, mechanical engineering, industrial design and other disciplines to meet its functional and appearance process requirements.
