Basic common problems of metal stamping parts-hardware

The processing of metal stamping parts is currently a widely used processing method. In the process of metal stamping, various processes such as drawing, trimming, punching, flanging, and flanging are involved. The production process is relatively complicated and some problems will inevitably occur. . So what are the common problems of metal stamping parts? The following hardware author will organize and introduce for you. 1. Burrs mainly occur in the cutting die and blanking die, and the gap between the cutting edges may be large or small, which will produce burrs. 2. Adhesion, scratches, defects on the surface of metal stamping parts or molds due to the friction between the material and the punch or die. 3. Concave and convex, foreign matter (iron filings, rubber, dust) mixed in the uncoiling line causes convex and concave. 4. The size of the punching hole is too large or too small, and the size of the punch is quite different. 5. The line is offset. When the part is formed, the part that is in contact with the mold first is squeezed and a line is formed. 6. Twisting, due to uneven stress, poor matching of drawbeads or poor control of the press slider, tortuosity and strain occur at the r-corner or embossed part of the part. 7. The strong pressure of the metal stamping parts processing on the material will cause the material to produce plastic deformation, which will cause the punching size to become larger, and when the strong pressure is reduced, the punching size will become smaller.
