High speed punch formation reason analysis - shrapnel stamping parts processing see

High-speed punch press shrapnel stamping parts processing production often uneven appearance problems, by the author tells us the main reason and processing methods: 1. There is no hole punch: in the process of processing stampings, workpiece internal air punch squeeze, can't eduction, result in artifacts appear uneven phenomenon. Processing method is: punch to increase air flow. 2. Stainless steel stamping blank uneven: billet surface uneven, lead to the workpiece surface is not flat. Better processing method: replace the material surface. 3. Material springback: elasticity, which leads to the workpiece is not smooth. Methods: increasing annealing or plastic process. 4. Material thickness tolerance is big, small thickness of the material, mold clearance slants big, lead to uneven shape. Methods: the right replacement materials. 5. Intensive large clearance, clearance when ambassador mold production leads to uneven effect on workpiece walls. Methods: adjust the die clearance.
