Several key points of appearance control of precision stamping parts

For the production of precision stamping parts, if the steel raw materials are imported stainless steel materials, the precision hardware parts that are punched out often have appearance defects such as spots, crushes, and scratches. At the same time, when this happens, add a vacuum cleaner and exhalation nozzle to the punch, but the effect is not satisfactory. In fact, to deal with this situation, there are many ways to solve it: 　　 1. Add a protective film, stick it on the material, and ask the supplier when buying the material. Do not add oil or water when the product is processed. It is best to let the product one by one during production. If the cutting blade is overlapped, it is easy to be crushed and bruised! The cost is higher and can be considered.　　2. It’s really not possible. Try different raw materials. Sometimes the performance of imported SUS and domestically produced is quite different. The performance of different domestic suppliers is also different, but while ensuring sufficient performance, cost control is also a way to solve the problem! 　　3, add a proper amount of punching oil, (to lubricate the punch, cut the mouth to prevent the generation of waste ) Cleaning the mold regularly, sharpening the punch in time, keeping the sharpness, and reducing the generation of debris are also effective methods!
4. The finish of the mold must be good, and the surface of the mold should be cleaned with a brush during processing. The surface of the mold and the workbench should be cleaned frequently. There should be no iron filings and other particulate impurities on the material or mold surface, but the production efficiency is reduced Relative to the rejection rate, it is acceptable!
