The cost of stamping parts production is mainly the cost of raw materials. According to statistics, the cost of raw materials in stamping parts accounts for more than 60% of the entire product cost. Therefore, the reasonable use of materials is a very important issue in the production of stamping parts.Layout with waste: punching along all contour lines of the workpiece, there is residual material between the workpiece and the workpiece, and between the workpiece and the strip. Because of punching along the closed contour of the blanking part, the quality of the blanking part and die life will be higher, but the utilization rate of the material is low.
Layout with less waste: cut or punch along the contour of part of the workpiece, and there are only overlaps between the workpiece and the workpiece, and between the side of the workpiece and the strip. The blanking of this layout method is only carried out along part of the contour of the workpiece, which is affected by the quality of the cutting strip and positioning and errors. Among them, the quality of the cutting is slightly worse, but the utilization rate of the material can reach 70% to 90%.
No waste layout: There is no overlap between the blanking part and the blanking part, and between the blanking part and the side of the strip. The blanking part is actually directly obtained by cutting the strip, and the material utilization rate can be Up to 85%-90%.
