Chaozhou metal stamping parts processing, what is the reason for the wrinkling of stamping parts + stamping accuracy is 0.01mm

The technician in charge of the processing and production of metal stamping parts in Chaozhou said that there are several factors that affect the wrinkling of stamping parts. Through specific practice, Xiaoshuo of hardware has summarized the following reasons for everyone, and let everyone understand: (1 ) The stretching depth affects the distribution of the material flow resistance along the cavity of the cavity and has a direct relationship with the stretching 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 produced around the workpiece, it should be judged that the blanking force is insufficient. Gradually increasing the blanking 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 sidewall wrinkles, so in addition to increasing the blank holder force, it is necessary to increase the pick-up and stretch ribs to increase the radial tensile stress in the plate and eliminate the wrinkles. (3) The influence of the radius of the die fillet If the fillet radius of the die is too large, the rougher flows into the die and passes through the die fillet, the smaller the bending resistance that produces 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. Accumulation of a large number of production practices has proved that the main cause of 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 the processing of Chaozhou metal stamping parts, 20,000+ sets of customized stamping die production experience, monthly 100+ sets of die processing, hundreds of precision processing production equipment, daily production capacity of 3 million punches, silk-like stamping accuracy 0.01mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled.
