The main points of the appearance control of precision stamping parts 'hardware'

by:Fortuna     2021-03-13
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, there are many ways to solve this situation. 1. Add a protective film and stick it on the material. Ask the supplier when buying the material. Do not add oil or water when the product is processed. Let the product be discharged one by one during production. The cutting knife is overlapped and easily crushed or bruised! The cost is higher and can be considered. 2. If it is not possible, try changing different raw materials. The performance of imported SUS and domestically produced products are sometimes quite different. The performance of different suppliers is also different, but while ensuring sufficient performance, cost control is also a way to solve the problem! 3. Add an appropriate 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 is also an effective method! 4. The mold finish 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 can be no iron filings and other particulate impurities on the surface of the material or mold, but the production efficiency is reduced. Compared with the rejection rate, it is acceptable!
