Shaodong metal stamping parts, what is the reason for the wrinkle of the drawing parts + the surface of the stamping parts is as smooth as jade

The technical staff responsible for the hardware production of Shaodong hardware stamping parts said that there are many reasons for the wrinkling of stretched parts during the stretching process. The novel summarizes the main reasons for the following aspects based on specific practices. Let's take everyone to understand. What causes the following reasons: (1) The drawing depth of the stamping part is too deep, which causes the sheet material to flow too fast in the process of feeding, 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 thoroughly 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, causing 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. The above are the common causes of wrinkles in the drawing process of metal stamping parts, and specific analysis is needed in specific problems. Find the specific reason according to the specific situation of the stamping parts. Hardware, 15 years of focus on Shaodong hardware stamping parts, 20,000+ sets of customized stamping die production experience, monthly processing of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punching times, and silk-like stamping accuracy up to 0.01 mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled.
