What causes wrinkling of stainless steel stamping parts in hardware processing plants?

Nowadays, stamping parts mold companies are gradually increasing, and many industries have increasingly higher requirements for stamping parts. Therefore, with the production link, the material used for the production of stamping parts also uses stainless steel, so what causes the wrinkling of stainless steel stamping parts in hardware processing plants ? Xiao Shuo takes everyone to understand: 1. Factors affecting wrinkling of stainless steel stamping parts and solutions (1) The effect of drawing depth; the flow resistance of stainless steel stamping parts is directly related to the drawing depth along the distribution of the concave die. In the concave and convex curve positions, excessive drawing depth of stainless steel stamping parts can cause uneven distribution of deformation resistance and form wrinkles, which should be avoided as much as possible. (1) Adjust the size of the blank holder force; when wrinkles are evenly produced around the workpiece, it should be judged as insufficient pressing force, and gradually increase the pressing force to eliminate wrinkles. When the stainless steel stamping parts stretch the tapered and hemispherical parts, most of the material is suspended when the stretching starts. It is easy to cause sidewall wrinkles, so in addition to increasing the blank holder force, it is necessary to increase the picking and stretching ribs to increase the radial tensile stress in the plate and eliminate the wrinkles. (3) The influence of the radius of the die fillet; the fillet radius of the stainless steel stamping die die is too large, and the blank flows into the die and passes through the die fillet. The smaller the bending resistance to bending deformation. The smaller the bending resistance, the more likely it is to cause wrinkles. The smaller the radius of the die, the greater the bending resistance of the bending deformation, the less likely it is to wrinkle, but it is easy to cause cracking and napping of stainless steel stamping parts. Accumulation of a large number of production practices has proved that the main cause of wrinkling of stainless steel stamping parts is the accumulation of materials during the stretching process and the excessive speed of local material movement. When formulating the actual solution, the corresponding mechanism of the mold should be adjusted from the above aspects, and good results will be achieved.
