Common problems in the processing of stainless steel stamping parts

Stainless steel stamping parts are very common metal stamping parts, and traces of it can be found in many places in our lives. For stainless steel, it is also a kind of stamping material that is very commonly used. Precision focus on precision stamping parts, metal insert injection molding processing customization for more than 10 years, has accumulated rich experience in stainless steel stamping parts processing. Stamping parts manufacturers will find many problems in the daily production of stainless steel stamping parts. Next, Precision will analyze the common problems in the processing of stainless steel stamping parts for everyone. 1. Scratches on the surface of stainless steel stamping parts In production, the scratches on the surface of stainless steel stamping parts are mainly caused by the relative movement of the stamping parts and the surface of the die. Under a certain pressure, the material and the mold surface directly rub, and the deformation heat of the material causes the metal shavings of the material to be deposited on the mold surface, causing scratches on the surface of the stamping parts. In addition, after production, due to packaging, transportation, etc., slight scratches may appear between the metal parts. 2. The stamping die wear of stainless steel stamping parts The die gap of stainless steel stamping parts is small, the alignment of the concave-convex die is not good, and the die seat, die guide assembly and turret insert are not accurate enough, which will cause die wear. In addition, continuous stamping using the same die for a long time will cause the punch to overheat, and multiple partial punching will cause the punch to deflect to the side, which will result in serious die wear. 3. Stripping of stamping die, such as the sharpness of the knife edge of stainless steel stamping parts, and whether the gap of the die is reasonable, will cause the striping problem of the die. In addition, if you use non-dedicated punching oil, due to the oxidation of the oil, problems such as adhesion and viscosity increase will also occur. 4. The quality of stamping oil The choice of stamping oil is also very important. The punching oil with excellent performance contains sulfur-chlorine composite additives, which can not only ensure better punching performance, but also avoid problems such as deformation, burrs and cracks of the workpiece. At the same time, in order to facilitate cleaning, low-viscosity stamping oil should be selected as much as possible.
