What are the general defects of the outward processing appearance of Jinhua metal stamping parts?

With the development of society, metal stamping products have been popularized in all walks of life. It is very important to process high-quality metal stamping parts. In the stamping process, many defects will occur on the surface of the product. What is going on? Jinhua hardware stamping parts outsourcing processing [hardware] let you know. In the process of processing and producing stamping parts, sometimes there will be problems such as impact line, slip line, collapse, pit, surface distortion, etc. For stamping plate parts, defects on the outer surface are not allowed, then this situation How is it caused? 1. The impact line and the slip line are mainly caused by the surface scratches caused by friction at the stress concentration place after the sheet metal and the mold contact during the stamping process. Collapse, concealed pit, 2. Surface distortion is mainly due to insufficient part deformation, small local material strain, and defects that appear after the external force is released; then how does the above-mentioned [hardware] eliminate these defects? 1. To eliminate the impact line, you can increase the drawing depth and change the blanking surface by changing the stamping fillet, the die fillet, and so on. 2. To eliminate the slip line, you can change the product shape (left-right symmetry), increase the resistance, etc. 3. To eliminate collapse and surface distortion, the level of stress gradient generated by the part in the deformation zone should be understood, and the uniformity of the plastic deformation of the product should be ensured as much as possible. At the same time, by increasing the resistance, increasing the local shape strain and other means.
