Causes and solutions of burrs on stamping parts

Different degrees of burrs occur in the punching process of stamping parts, and it is difficult to prevent such poor stamping. Only through the improvement of the production process of stamping parts, optimizing the production conditions of stamping parts, and then reducing the occurrence of defective burrs 1. If the blanking gap is too large, too small or uneven, the burr will occur. The installation of the stamping die is improper: the gap of the mold guide part Too large, poor accuracy of asymmetric press during installation of concave and convex molds: the guide rail gap of the press is too large, the bottom surface of the mold and the parallelism of the press table are not close, the stroke of the mold slide and the straightness of the press table are not uniform, and the pressure The machine table has poor rigidity and deflection occurs during the stamping process, causing the gap between the die and the press to change. The stamping data is too large: the stamping data is not flat when the stamping data is fed, resulting in uneven force 2. The die edge is worn or the tool is gnawed Injuries can cause burrs during the production process. The hardness of the raw material of the mold concave and convex mold is not good, the surface of the mold is poorly processed, and the mold knife edge is poorly wear-resistant. The stamping die is not smooth during operation, resulting in excessive knife edge wear. The mold is not maintained in time, is not demagnetized, and is not timely. Grinding the edge of the die 3. The stamping material has poor contact with the die or the punch during the stamping process, and the shape of the stamping part and the die edge does not conform to the shape of the die during the stamping process, causing burrs to occur. The occurrence of defective parts burrs cannot be prevented during the stamping process, and the defective burrs that have occurred can be processed again by filing, electrolysis, rolling, grinding and other methods to eliminate the burrs that have occurred.
