Electronic metal stamping parts manufacturers, how to reduce the bumps of metal stamping parts + 15 years of experience

The production staff responsible for the manufacture of electronic hardware stamping parts said that most of the causes of metal stamping parts are caused by dust or iron filings attached to the raw materials or the appearance of the mold. It degrades the appearance of the product and also greatly reduces the productivity. So how do we avoid this problem? The following article summarizes the following five methods to reduce the bumps of metal stamping parts based on practice.　　 5 methods to reduce the unevenness of stamping parts: 　　 1. Inspection and correction of the drawing die: The drawing die needs to be regularly inspected and maintained to reduce the occurrence of unevenness and maintain a stable state. The usual method is to use samples to check the bonding scratches and processing surfaces of the blank holder (die fillet, punch fillet).　　2. Inspection and correction of the shearing die: The reason for the unevenness after the shearing process is that iron powder is produced during the shearing process. Therefore, the iron powder must be observed before punching to avoid the occurrence of unevenness.　　3. Appropriate robot speed: For semi-automatic drawing die production, when the drawing punch is at the lower die position and the robot speed is fast, the burrs will fall on the upper part of the punch, causing bumps. In order to avoid this kind of problem, we can do a discharge test of the part before production, and set the speed and discharge angle of the manipulator reasonably so that it will not touch the part and the lower mold. 4. Check the cut surface: When cutting the coil material, the wear and breakage of the cutting die will produce a lot of tiny iron powder attached to the cutting edge, so the double cut surface must be checked in the material area or the press line before stamping production, and cleaned in time The sheet is deburred.　　5. Inspection of sheet metal cleaning device: Before stamping production, it is necessary to inspect and trim the cleaning device at the same time, so that it may clean the sheet material more effectively. This is also very necessary, and it is also necessary to pay attention to the roller gap and the quality of the cleaning oil. The detailed method is to apply red paint on a steel plate and then make it clean and settle. Currently, check the antecedent shape of the red paint being cancelled. Assuming that the removal rate is not up to standard, it needs to be checked and trimmed, cleaned and settled. When the cleaning oil is lacking, it needs to be cut in time. Hardware, 15 years of focus on electronic hardware stamping parts manufacturers, 20,000+ sets of customized stamping die production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy 0.01mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose to rest assured!
