Before the precision metal stamping parts are processed and drawn, the blank of the metal stamping parts shall be wiped clean to avoid that the surface or material surface is not clean when the mold is working, which may mix with dust and other debris, damage the surface of the metal stamping parts, and affect the product quality. When stamping the structural shape of parts, it is recommended to use simple and reasonable surfaces and their combinations, such as planar, cylindrical and helical surfaces, while minimizing the number and area of machined surfaces. Stamping usually does not produce chips and waste materials, consumes less materials, and does not need other heating equipment, so it is a material saving and energy-saving processing method, and the cost of producing stamping parts is low. Stamping parts are highly efficient, easy to operate, and easy to realize mechanization and automation. As stamping depends on stamping dies and stamping equipment to complete processing, the number of strokes of ordinary presses can reach tens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute. Each stamping stroke can obtain a stamping part, so the production of metal stamping parts can achieve efficient batch production.
Processing of precision metal stamping parts
The processing cost of stamping increases with the improvement of precision, especially in the case of high precision. The requirements for quality standards of stamping parts are getting higher and higher. The main difficulty of the current stamping process is precision stamping or full bright band. All stamping parts need blanking to meet the required specifications and styles. The blanking process will lead to burrs in the cutting part of the workpiece, collapse angle on the surface, insufficient brightness, and even local fracture. Therefore, we should attach great importance to such a situation, otherwise it will cause great problems.
