Forming accuracy of metal stamping parts

Mold manufacturing cost and life are important factors that affect the cost and quality of metal stamping parts. Mold design and manufacturing require more time, which prolongs the production preparation time of new metal stamping parts. The design principles of metal stamping parts: 1. The metal stamping parts must meet the product use and technical performance, and be easy to assemble and repair. 2. Hardware stamping parts must be beneficial to improve the utilization rate of metal materials, reduce the variety and specifications of materials, and reduce the consumption of materials as much as possible. Use low-cost materials where permitted, and make the parts as waste-free and waste-less as possible. 3. The metal stamping parts must be simple in shape and reasonable in structure, in order to simplify the mold structure and simplify the number of processes, that is, use the least and simplest stamping process to complete the processing of the entire part, reduce the use of other methods to process, and facilitate the stamping operation , It is convenient to organize the realization of mechanized and automated production to improve labor productivity. 4. For metal stamping parts, under the condition of ensuring normal use, try to make the dimensional accuracy level and surface roughness level lower, and it is conducive to product interchange, reducing waste and ensuring stable product quality. 5. Metal stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and to extend the service life of the die. The precision and structure of the mold directly affect the forming and precision of Dongguan hardware stamping parts. Standardization and development of mold bases, mold bases, and guides. Simple molds (for small batch production), composite molds, multi-station progressive molds (for mass production), and the development of rapid mold change devices, which can reduce production preparations for metal stamping parts The workload and shortening of preparation time enable the advanced stamping technology suitable for mass production to be reasonably applied to small batch and multi-variety production.
