Metal stamping manufacturers, do you know all about stamping and stretching?

Metal stamping manufacturers, in the processing and production, drawing parts is a relatively common process, and it is also a process with a higher degree of difficulty, and often encounters wrinkling problems in drawing. So what causes it? Xiaoshuo understands with you: 1. Adjust the blank holder force. During the deep drawing process, the blank holder force should not be too large or too small, and it should be uniform everywhere. Too small a blank holder force is easy to cause wrinkles in the drawn part, and a too large blank holder force is easy to break the drawn part, the blank holder force is uneven, and the drawing part may wrinkle on one side. Therefore, attention should be paid to adjusting the blank holder force appropriately during deep drawing. 2. The thickness of the measured material is incorrect or the negative difference is too large, the drawn part is easy to wrinkle, and the uneven thickness of the material will cause wrinkles on one side of the drawn part. The material with uneven thickness can be rolled once before drawing. 3. If the gap between the convex and concave molds is too large, the straightening effect will be reduced, and the material is easy to wrinkle. But the gap is uneven, and the drawn part will wrinkle on one side. The gap between the convex and concave molds can be properly trimmed. 4. Die fillet The die fillet is too large, which reduces the contact area between the blank holder and the material and causes the drawing part to wrinkle. The die fillet can be properly trimmed. 5. For some deep drawn parts with complex curved surfaces, especially small flange parts, drawing ribs can be set on the mold to increase the flow resistance of the material to prevent the drawn parts from wrinkling.
