Process of stamping parts processing and manufacturing

Stamping processing is the production technology of using the power of conventional or special stamping equipment to directly subject the sheet metal to the deformation force and deform in the mold, so as to obtain product parts with a certain shape, size and performance. Sheet materials, molds and equipment are the three elements of stamping processing. Stamping is a method of metal cold deformation processing. Therefore, it is called cold stamping or sheet stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology. The die used for stamping parts is called stamping die, or die for short. The die is a special tool for batch processing of materials (metal or non-metal) into the required stamping parts. Punching dies are very important in stamping. Without a die that meets the requirements, mass stamping production will be difficult; without advanced stamping dies, advanced stamping processes cannot be realized. The stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only when they are combined can stamping parts be obtained. Stamping parts processing 1. Determine the amount of deformation compensation according to the material, product structure, etc. 2. According to the compensation amount, design the die to punch out finished or semi-finished products 3. Process semi-finished products to finished products 4. Unfavorable phenomena include cracks, wrinkles, strains, and uneven thickness , No forming, etc. Tapping and thread processing: 1. The internal thread first drills the bottom hole diameter and depth (the bottom hole size is determined according to the thread specification, search a large number on the Internet); the external thread is first processed from the outer circle to the large diameter of the thread (Determine the size according to the thread specifications, search a large number on the Internet) 2. Processing thread: internal thread tapping with corresponding grade tap; external thread turning with thread cutter or die sleeve threading. 3. Unfavorable phenomena include random threading, Materials such as non-uniform dimensions and unqualified thread gauge inspections are mainly selected according to the requirements of use, such as copper, aluminum, low carbon steel and other metals or non-metals with low deformation resistance, good plasticity, and good ductility. As for the inspection specifications, they should be formulated according to product requirements. National standard thread gauges are inspected. For hole inspection, special plug gauges can be designed according to the national standard or the standard size plug gauges of the national standard can be purchased.
