The principle of cutting process layout of metal stamping parts, can be collected

When it comes to the process cut of metal stamping parts, an engineer with 20 years of experience in mold design told the author that the size and shape of the process cut depends on the area in which it is located and the requirements for external supplementary materials. Generally, the following requirements should be followed. The following principles: 1. The cut of the metal stamping part is adapted to the contour of the local protrusion shape to make the material flow reasonably; 2. There should be enough overlap between the cuts so that the punch can tension the material to ensure a clear shape. Avoid defects such as ripples, so that you can get a good quality of the flanging hole after trimming; 3. The cut part of the incision, that is, the opening should be adjacent to the edge of the protruding part, or the area that is easy to break; 4. The number of incisions should be guaranteed The material at all parts of the protrusion is uniformly deformed, otherwise the ripples may not be prevented; The above article comes from the processing of metal stamping parts and the customization of automobile stamping parts for 18 years.
