Precision stamping parts, covering parts forming 'hardware'

The forming of the cover of precision stamping parts is generally composed of blanking (or shearing), deep drawing, trimming, flanging, shaping, punching, bending, bulging, cutting and other basic processes as required. The typical structure is Covers generally require 4-6 processes. There are many factors that need to be considered in process design, mainly the following aspects: (1) Research on stamping performance, processing methods 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 cover, and determine the equipment used in each process. (5) Re-discuss the process design with stamping as the main focus, because even a good designer cannot be proficient in the work of each department, and a large amount of information can be collected through the discussion, thereby improving 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 records. (6) Economic analysis, with the goal of reducing costs and increasing efficiency. With the rapid development of computer technology, intelligent technology and electronic information technology, the development of stamping process design technology for precision stamping parts cover parts should be intersected and closely integrated with many disciplines such as manufacturing technology, intelligent technology, electronic information and computer integration technology. This represents It is the direction of scientific and technological development in this field in the 21st century, which is economical, cutting-edge and strategic.
