Forming of precision stamping parts of cover parts
The forming of the cover of precision stamping parts is generally composed of blanking (or shearing), deep drawing, trimming, flanging, shaping, punching, bending, bulging, incision and other basic processes arranged and combined as required. The typical structure Covers generally require 4-6 processes. There are many factors to be considered in process design, mainly in the following aspects:
(1) Research the stamping forming performance, processing method and processing performance.
(2) A scheme that has fewer design procedures 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 punching force according to the size of the precision stamping parts cover, and determine the equipment used in each process.
(5) Re-discuss the process design with stamping as the main subject, because even a good designer cannot be proficient in the work of each department. Through the discussion, a large amount of information can be collected to improve the design level. During the analysis and discussion, personnel from quality control, mold manufacturing, debugging and use departments should be invited to participate, and records should be kept.
(6) Economic analysis, with the purpose of reducing costs and increasing efficiency.

With the rapid development of computer technology, intelligent technology and electronic information technology, the development of the stamping process design technology of precision stamping parts cover parts should be closely integrated with many disciplines such as manufacturing technology, intelligent technology, electronic information and computer integration technology. This represents It is economic, cutting-edge and strategic in the direction of scientific and technological development in this field in the 21st century.
