Problems solved by technology

Before stamping the blank, the mold needs to position the blank through the positioning device. Generally, the positioning device is fixed on the fixing plate of the lower die; because there is only one positioning dimension on the fixing plate of the lower die of the current stamping die, that is, the positioning device is on the lower die fixing plate. The position of the fixed plate cannot be adjusted, which leads to a pair of molds that can only process parts of one specification and size, but cannot process parts of different specifications and sizes. The utilization rate of equipment is low, waste of resources, and product quality Higher processing costs
In actual production, in order to improve production efficiency, the processing method of three-jaw one-time forming is adopted. Although the production capacity of the equipment can be improved, due to the relatively large stamping force on the parts during the stamping process, the deformation of the parts exceeds the technical standard requirements. The yield rate is low, and the follow-up processing is also relatively difficult, resulting in relatively high production costs

Abstract

The invention relates to a multi-purpose stamping die comprising a lower die plate and a forming module, wherein the forming module is arranged in a forming groove in the lower die plate; a positioning groove is formed in the lower die plate; and a first positioning module is placed in the positioning groove, and can be replaced by other positioning modules. According to the invention, the finished product ratio of one-time stamping is improved; the utilization ratio of the die is improved; resources are saved; and the processing cost is reduced.

Description

technical field [0001] The invention relates to the field of molds, in particular to a stamping mold for a rotating piece. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Before stamping the blank, the mold needs to position the blank through the positioning device. Generally, the positioning device is fixed on the fixing plate of the lower die; because there is only one positioning dimension on the fixing plate of the lower die of the current stamping die, that is, the positioning device is on the lower die fixing plate. The position of the fixed plate cannot be adjusted, which leads to a pair of molds that can only process parts of one specification and size, but cannot process parts of different specifications and sizes. The utilization rate of equipment is low, waste of...
