Save the production cost of stamping parts from 5 aspects！
1, the workpiece design should have good stamping process. The structure shape should be as simple as possible, and the dimensional accuracy should be as low as possible, without affecting the requirements of the workpiece. In this way, the number of processes can be reduced, and the die structure can be simplified so as to reduce the variable cost and reduce the constant cost.
2, the formulation of the process should be as reasonable as possible. In stamping production, it is often an effective way to reduce cost by making reasonable process plan. Stamping the same workpiece, usually can adopt several different process plans, and its economic effect is not the same. Therefore, various schemes should be analyzed and compared, and a reasonable scheme should be chosen. Generally speaking, in mass production, it is necessary to concentrate the operations as much as possible and adopt compound or continuous stamping process, which is helpful to reduce the variable cost. While small batch production, the use of single process, scattered stamping or simple die stamping is appropriate. For asymmetric workpieces, symmetrical stamping should be used as much as possible, which can not only make the deformation even but also reduce the cost.
3, the material selection of the workpiece should be appropriate, material utilization rate is high. In stamping process, the workpiece material costs accounted for about 60% of the cost of manufacturing. Therefore, under the premise of ensuring the workpiece using requirements and stamping process performance, improve material utilization, reduce the edge and reasonable layout, make full use of technology and material structure with thin material waste, generation of thick material, a black metal generation of non-ferrous metals, are effective ways to reduce the costs of stamping.4, as far as possible to reduce the stamping die manufacturing costs. Stamping die cost in stamping parts of a certain proportion, according to the relevant information about the cost of stamping parts 10% ~ 30%. In order to reduce the cost of stamping die, the stamping die structure should be as simple as possible, the material selection should be as reasonable as possible, and the stamping die processing requirements should not be too high. At the same time, standard die parts should be used as much as possible to expand the typical structure of stamping die and shorten the manufacturing cycle of the stamping die.
5, as far as possible to achieve the stamping process of mechanization and automation. In the mass production, to realize the mechanization and automation of the stamping process, from the two aspects of safety and cost reduction, it will become the direction of the stamping process. In this case, although the cost of the mold is higher, but because of high productivity and large output, the cost of the die allocated to each workpiece is lower than that of the small batch production. Therefore, the cost of stamping parts can be significantly reduced.
