Wrinkle Analysis Of Auto Hardware Tensile Parts

In the process of stamping and drawing, sometimes wrinkling occurs, which affects the quality and processing efficiency of stamping and drawing products. Zhejiang Yiwei Precision - For 30 years, it has insisted on providing customers with customized processing services for precision stamping parts, with rich experience. Next, let's analyze the reasons for the wrinkling of automotive hardware tensile parts.

Stamping and drawing automotive hardware drawing parts

1. The drawing depth of the stamping part is too deep, which causes the sheet material to flow too fast during the feeding process of the part, resulting in wrinkles.

2. The mold positioning design is unreasonable, which leads to the inability to press the material during the stretching process of the stamping part or the pressing edge is too small, which leads to the inability to press the material during the stretching process, resulting in wrinkling.

3. During the stretching process, the R angle of the die is too large, so that the punch cannot press the material during the stretching process, causing the sheet to flow too fast to form wrinkles.

4. The gap between the convex and concave dies is too large, so that the material cannot be pressed during the stretching process, resulting in wrinkling.

5. The pressure of the ejector rod is too small, so that the stamping parts are not formed completely and wrinkle is formed.

6. The pressing ribs are unreasonable, the pressing ribs are too small and the position is incorrect, which cannot effectively prevent the sheet from flowing too fast and form wrinkles.
