Stamping parts processing, five methods allow you to solve the unevenness of stamping parts

In the processing of stamping parts, there are often problems with uneven surface of the stamping parts during the production process. What caused it? How to solve it to improve efficiency and quality? Xiaoshuo sorted out five points and communicated with you: 1. Inspection and correction of drawing dies: Regular inspection and maintenance of drawing dies are required to reduce the occurrence of convexities 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. Proper manipulator speed: For semi-automatic drawing die production, when the drawing punch is at the lower die position and the manipulator speed is fast, burrs will fall on the upper part of the punch, causing bumps. In order to avoid this kind of problem, we can do the discharging test of the part before production, and set the speed and discharging 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 material cleaning device: It is necessary to inspect and trim the cleaning device at the same time before stamping production, so that it may clean the sheet material more effectively. This is also very necessary, and the roller gap and the quality of the cleaning oil should also be paid attention to. 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.
