What to do if there are pull marks on the surface of stamping parts

In the processing of stamping parts, if there are pull marks, it will affect its quality and ultimately affect the profit of the production enterprise. Therefore, as a stamping parts manufacturer, we must avoid such problems as much as possible. So, what kind of measures should we take? In response to this problem, we will give you a brief introduction next. First, we need to find out the specific reasons, and then take targeted measures based on the specific reasons. For example, if it is found that the surface of the punch or the die is sharply crushed, which leads to serious pull marks on the surface of the stamping part, then it should be repaired in time, such as grinding or polishing. Method to deal with. If the gap between the convex and concave molds is too small or the size is different, which causes the problem of scratches, then the distance between the convex and concave molds should be re-adjusted until it is suitable. If, after investigation, it is found that the surface of the die fillet is relatively rough, which leads to scratches on the surface of the stamping part, then the die fillet radius should be polished. In addition, if it is due to the presence of dirt on the surface of the die or the surface of the material during stamping, it will eventually cause the workpiece to be injured. At this time, it is necessary to keep the surface of the male and female molds clean. It is best to clean it before starting work. In addition, if the hardness of the convex and concave molds is too low, or the surface is stained with metal scraps, it may also cause the stamping parts to appear pull marks. For this situation, we not only need to increase the surface of the convex and concave molds. Hardness also requires frequent inspection of the surface condition of the convex and concave molds during the stamping process, and timely removal of leftover metal scraps. In the last case, if the quality of the lubricant used is too poor, this situation will also occur. At this time, we need to select the corresponding lubricant according to the situation. If necessary, we should filter the lubricant first. In use, to prevent impurities from damaging the surface of the stamping parts.
