Precision stamping parts cover forming

Precision stamping parts The forming of precision stamping parts covers generally consists of basic processes such as blanking (or shearing), deep drawing, trimming, flanging, shaping, punching, bending, bulging, and notching. Covers with typical structures generally require 4-6 processes. There are many factors that need to be considered in the process design, mainly the following aspects: 　　 (1) Research on stamping performance, processing methods, and processing performance.　　 (2) The scheme that has the least design process and can meet the performance requirements of the cover. In mass production, multiple processes should be combined into one process as much as possible, and a single process mold should be used for small batches.　　 (3) Preliminarily determine the mold structure and the dimensions that affect the strength and life.　　 (4) Calculate the pressing force according to the size of the cover, and determine the equipment used in each process.　　(5) Re-discuss the process design with stamping as the main focus, because even the best designer cannot be proficient in the work of each department. Through discussion, a large amount of first-hand information can be collected to improve the design level. During the analysis and discussion, personnel from the quality control, mold manufacturing, debugging and use departments should be invited to participate, and make a record.　　 (6) Economic analysis, with the goal of reducing costs and improving efficiency. With the rapid development of computer technology, intelligent technology and electronic information technology, the development of automotive panel stamping process design technology should be intersected and closely integrated with many disciplines such as advanced manufacturing technology, intelligent technology, electronic information and computer integration technology. This represents The direction of scientific and technological development in this field in the 21st century is economic, cutting-edge and strategic.
