Other stamping materials other than workpieces in precision stamping, including process waste and structural waste. All the contours of the material are punched out, and there is a process residual between the workpiece and the workpiece and between the workpiece and the strip. Because of the punching along the closed contour of the blank, the quality of the blank and the life of the die are relatively high.
The precision stamping part is cut or punched along the outline of the workpiece part, and there is a lap between the workpiece and the workpiece, and between the workpiece and the side of the strip. The blanking of this kind of arranging method is only along the contour of the part of the workpiece, which is affected by the quality and positioning of the trimming strip and the error. The quality of the cut piece is slightly poor, but the utilization rate of the material can reach 70%~90%.
The precision stamping part is between the blanking part and the blanking part, and there is no overlap between the blanking part and the side of the strip. The punching part is actually obtained directly by cutting the strip, and the material utilization rate can reach 85. %-90%. However, this method of sorting will make the quality of the cuts slightly worse.
The three layout methods have their own advantages and disadvantages, so they are selected according to the actual situation when designing the precision stamping parts. Need to know more welcome to pay attention to this number and message consultation.
