Longkou hardware stamping parts, what is the reason for the wrinkling of stamping parts + 3 million punching next-day production capacity manufacturers

The hardware stamping processing technicians of the manufacturer responsible for the production of Longkou hardware stamping parts said that there are several factors that affect the wrinkling of stamping parts. Xiaoshuo sorted out some and took everyone to understand: 　　 (1) The depth of drawing affects the flow resistance of the material. The distribution of the cavity is directly related to the drawing depth. In the concave and convex curve positions, excessive stretching depth can cause uneven distribution of deformation resistance and form wrinkles, which should be avoided as much as possible.　　 (2) Adjust the size of the blanking force. 　　 When wrinkles are evenly generated around the workpiece, it should be judged as insufficient pressing force. Gradually increasing the pressing force can eliminate the wrinkles. When the tapered and hemispherical pieces are stretched, most of the material is suspended when the stretch starts. It is easy to cause side wall 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) Influence of the radius of the die fillet 　　 The fillet radius of the 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 the part.　　Through the accumulation of a large amount of production practice experience, it is proved that the main reason for the wrinkling of 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. Hardware, 15 years of focus on Longkou hardware stamping parts, 5000 square meters production workshop, hundreds of precision processing production equipment, more than 20 Ru0026D and design engineers, monthly processing capacity of 100+ sets of molds and daily production capacity of 3 million punching times, and the stamping accuracy can reach 0.01mm, 16 quality inspection layers are strictly controlled. It can quickly solve the urgent problem of time when choosing hardware stamping processing, solve the problem of stamping accuracy, and solve the problem of production quality. For 15 years, I have been conscientious and dedicated to the results of your needs for the results of work!
