Tell you a way to solve the surface scratches of stainless steel stamping parts

The forming process in stainless steel stamping die products is very common. The stamping products produced by ordinary forming structures are generally not very good in appearance, and there will be some scratches and indentations on the forming parts. During the design process, some stamping The part is an appearance part, it is required that the surface is free from scratches and other bad conditions. Is there any way to solve it? Today the author will study with you: First of all, to solve the surface defect of stainless steel stamping parts, we must first figure out why this appearance occurs. What causes the bad problem? When we use ordinary structural molds for forming, due to the relative sliding of the punch and the material surface, if the material is soft, it will inevitably leave scratches on the material surface. Secondly, analyze the bad state Find out the final cause and check: 1. Whether there is iron filings or other foreign matter on the surface or inside of the stainless steel stamping parts before forming; 2. Whether a large number of burrs are generated on the forming edge; 3. Check whether the stainless steel raw materials meet the requirements; solve the stainless steel stamping The simplest method for poor surface of parts is to change the structure to change the sliding friction of the forming punch into rolling friction, which can minimize scratches. You can also add punching oil or paste a layer of plastic film on the surface of the material to prevent For scratches, the flap structure can be used if conditions permit, and this structure will not cause surface problems.
