Precision of stamping parts

Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, ribs, buckling or flanges that are difficult to manufacture by this skilled hand to improve its rigidity. Due to the rejection of rough molds, the precision of the workpiece can reach the micron level, and the precision is high, the specifications are consistent, and holes, bosses, etc. can be punched out. In actual production, process tests similar to the stamping process are commonly used, such as drawing performance test, bulging performance test, etc. to test the stamping performance of the material to ensure the quality of the finished product and a high pass rate. In addition to the hydraulic press for forming thick plates, the stamping equipment usually adopts a stagnant press. Focusing on the current high-speed multi-station stagnation press, set up equipment configuration decoiling, finished product collection, transportation and other stagnation, as well as mold library and quick mold change placement, and use the computer French tube bundle to form a passive stamping production with high production rate and high production rate. line. Under the condition of producing dozens or hundreds of stamping parts every minute, the stamping and outputting processes are completed in a short period of time, and personal, equipment and quality incidents often occur. Therefore, the safety of stamping is a very important issue.
