Five solutions for metal stamping parts


The cause of the unevenness of the metal stamping parts is mostly caused by the adhesion of dust or iron filings to the appearance of the raw materials or the mold, which makes the appearance of the product low and the productivity is greatly reduced. So how do we avoid this kind of problem? Let me summarize the following five ways to reduce the bumps of metal stamping parts according to the practice.

5 ways to reduce the unevenness of stamping parts:
1. inspection and correction of the shearing die: The reason why the convexity and concave appear after the shearing process is that iron powder is generated during the shearing process, so it is necessary to observe the iron powder before the punching to avoid the occurrence of the convexity and concave.
2. inspection and correction of the drawing die: The drawing die needs to be regularly inspected and maintained to reduce the occurrence of bumps and maintain a stable state. The usual practice is to use a sample to check the bond scratches on the bead and the condition of the machined surface.
3. Check the cross-section: When the coil is cut off, the wear and damage of the cut-off mold will cause a lot of tiny iron powder to adhere to the cutting edge. Therefore, it is necessary to check the double-section section in the material area or the press line before the stamping production, and clean it at the same time. The sheet removes burrs.
4. Appropriate manipulator speed: For semi-automatic drawing die production, when the drawing die is in the lower die position and the manipulator speed is fast, the burr will fall on the upper part of the punch, causing the convex and concave. In order to avoid this problem, we can make the discharge test of the part before production, and reasonably set the speed and discharge angle of the manipulator so that it does not touch the part and the lower part.

5, the inspection of the sheet cleaning device: the metal stamping parts must be inspected and trimmed at the same time before the production, so that it may be more effective to clean the sheet, which is also very necessary, and also need to pay attention to the roller gap and cleaning oil quality.
