How to avoid the bump problem of metal stamping parts

Hello everyone, I am the author of Guangdong Precision. I believe that when you are processing and producing metal stamping parts, you will encounter products that have unevenness. Most of the unevenness problems of stamping parts are due to the raw materials or the adhesion of iron filings or dust outside the mold. So how to avoid the bump problem of metal stamping parts? 1. We need to inspect and maintain the drawing die regularly to keep it stable to reduce unevenness. Generally, samples are used to test the blank holder and the machined surface to ensure that there is no problem. 2. In the semi-automatic drawing die production, we need to adjust the speed of the manipulator and the position of the material, otherwise the burr may fall on the punch, resulting in unevenness. 3. In addition to the drawing die, the trimming die should also be checked for iron powder during the cutting process, and attention should be paid to cleaning it. 4. When the cutting die breaks the coil material, there will be iron powder during wear. These iron powder are adsorbed on the cutting edge. We must clean the sheet before stamping and then stamping.
