Hangzhou hardware stamping parts processing, what are the reasons for the wrinkling of stretched parts +15 years of experience manufacturers

The technician in charge of the processing of hardware stamping parts in Hangzhou said that there are many reasons for the wrinkling of stretched parts during the stretching process. The following Xiaoshuo will analyze several main reasons for everyone, including the following aspects: (1) Stamping The drawing depth of the part is too deep, which causes the sheet material to flow too fast in the process of feeding the part, and wrinkles are formed. (2) In the drawing process of the stamping parts, the concave die R angle is too large, which causes the punch to be unable to press the material during the drawing process, causing the sheet material to flow too fast and form wrinkles. (3) The pressing ribs of the stamping parts are unreasonable, the pressing ribs are too small and the position is incorrect, which cannot effectively prevent the sheet from flowing too fast and forming wrinkles. (4) The pressure of the ejector rod is too small, so that the stamping parts are not formed completely and wrinkles are formed. (5) The mold positioning design is unreasonable, causing the stamping parts to be unable to hold the material or the blanking edge is too small during the drawing process, resulting in the inability to hold the material during the drawing process, resulting in wrinkles. (6) The gap between the convex and concave molds is too large, resulting in the inability to hold down the material during the stretching process, causing wrinkles.
