What items need to be calculated for the metal stamping process? Hardware stamping is a process that uses a punch and die to deform or break stainless steel, iron, aluminum, copper and other plates and dissimilar materials to achieve a certain shape and size. The metal stamping process can be roughly divided into separation process and forming process (also divided into bending, drawing and forming). The separation process is to separate the stamping part and blank along a certain contour line during the stamping process, and the quality of the separation section of the stamping part must also meet certain requirements; The forming process is to make the stamping blank plastic deformation without damage, and transform it into the required shape of the finished product. At the same time, it should also meet the requirements of dimensional tolerance and other aspects. What items need to be calculated for the metal stamping process?
1. Calculation of blank size and semi-finished product size of metal stamping parts.
2. Calculation of metal stamping process force. Including blanking force, bending force, tensile force, blank holder force, unloading force, pushing force, etc;
3. Calculation of pressure center of metal stamping die. This calculation should be paid more attention to the dies for stamping complex shaped workpieces, punching dies with multiple punches and progressive dies;
4. The determination of the clearance and fillet radius of the male and female dies, and the size calculation of the working parts of the male and female dies.
5. Relevant calculations of elastic elements. For example, the free height of rubber or spring and the determination of pre-compression shrinkage;
6. Strength check of relevant parts of metal stamping die. For example, the strength check of the slender punch, the weak die, the ejector rod with large force and the threaded rod of the elastic buffer.
The above contents are the main contents of the calculation of the metal stamping process. Only through these calculation data can the reasonable design of the metal stamping mold and the metal stamping production process be carried out, and the appropriate metal stamping equipment can be selected, and the metal stamping production can be successfully implemented.
