It is a duty to do every job well at the moment, so what process will go through in the stamping process and what details need to be paid attention to? 1. The process of blanking and punching is exactly the same, but the purpose is different. When blanking, the separated part is the finished product, and the remaining periphery is the waste; the punching is to obtain the hole, the punched sheet is the finished product, and the separated part is the waste. Blanking and punching are collectively referred to as blanking. Both the punch and the die of the blanking die have sharp edges, and there is a gap between the punch and the die that is equivalent to 5%-10% of the plate thickness to ensure a neat cut and less burrs. 2. Bending is to make the workpiece obtain a variety of different shapes of bend angles. The working part of the bending die that makes the workpiece bend should have an appropriate fillet radius r to avoid cracking when the workpiece is bent. 3. Deep drawing: Deep drawing is the process of making a flat blank into a cup-shaped or box-shaped piece. The edge of the punch and die of the drawing die should be rounded to avoid the workpiece from being cracked. There should be a gap slightly larger than the thickness of the sheet between the punch and the die (generally 1.1-1.2 times the thickness of the sheet) in order to reduce friction. In order to prevent wrinkles, the edge of the blank needs to be pressed tightly with a pressing plate (binder ring).
