One solution to the difficult problems of metal stamping parts-hardware

Hardware allows you to master the method to solve the difficult problems of metal stamping parts. Why are there marks or scratches on the surface quality of metal stamping parts? Let's analyze them one by one. There are many situations that make up the surface quality of stamping products. For example, the surface quality of coils, sheets, and molds will directly affect the appearance quality of the final stamping product. The operation in stamping and the clamping and unloading of the station equipment can also damage the surface quality of the part. Therefore, in each link of the entire manufacturing, full consideration should be given to the details and try to avoid quality defects. The appearance of the stamped product. Common undesirable phenomena of coil materials mainly include the following aspects: 1. There are foreign objects on the surface or inside of the material; 2. The foreign objects are peeling off, and the coil has a scar-like appearance; the coil is bad 3. The corners of the coil are damaged; 4. The corners (20 ～30mm) Deformation or wrinkles due to uneven stress; 5. Scratches (may be caused by foreign substances on the surface of the roller); 6. Roller sliding caused by; 7. Irregular breakage of the edges; 8. Pressure on the back of the roll after foreign matter enters Bulge (foreign objects fall and disappear); 9. Roll traces (foreign objects attached to the rollers); 10. Poor materials beyond the rules; The above shows that the surface quality of metal stamping parts is related to many factors, many of which are still unavoidable of. In addition, there are foreign objects that can clearly see groove marks on the surface depth, which is also a very common reason for poor surface quality of stamping parts. According to the theory, it is not difficult to find that in the above content, items 5, 8, and 9 are the most frequent defective parts.
