Stamping process is the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment to deform and deform the sheet metal directly in the die. Sheet metal, die and equipment are the three elements of stamping. Stamping is a method of metal cold deformation processing. Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to the material forming engineering technology. Stamping die is called stamping die, referred to as stamping die. Die is a special tool for processing material (metal or nonmetal) into batch parts. Stamping die is very important in stamping, there is no need to meet the requirements of the stamping die, batch stamping production is difficult to carry out; without advanced stamping die, advanced stamping process can not be realized. Stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing, only they can be combined with each other to obtain stamping parts.
Stamping parts processing
1. determine the amount of deformation compensation according to the material, product structure and so on,
2. according to the amount of compensation design mold stamping out finished products or semi-finished products
3. processing semi-finished products to finished products
4. bad phenomena include crack, wrinkle, strain, uneven thickness, forming and other tapping and thread processing:
1. internal thread first drilling bottom hole diameter and depth (bottom hole size according to the thread specification size, a lot of online search); first external thread machining to large diameter thread size (according to the thread specification determine the size of the online search, a lot of) 2. processing thread: thread taps tapping the corresponding grade; external screw thread cutter turning or die threading can be 3. wire buckle, including the bad phenomenon of chaos is not uniform size, thread gauge inspection unqualified materials mainly according to the use requirements of selected copper, aluminum, low carbon steel, low deformation resistance, good ductility and good ductility of metal or non metal for inspection specification is made according to product requirements. A thread thread inspection standard, inspection hole according to the standard size of GB plug design special plug or buy gb.
