Description
Technical Field
The utility model belongs to the technical field of deep step stamping part dies, and particularly relates to a double-acting deep step extension die.
Background
For many years, deep step stainless steel stamping has employed a conventional double-action die stamping process. However, the flanging deformation of the deep-step stainless steel stamping part is relatively large, so that an annealing and excircle turning process is required to be added before flanging. Even so, the flanging deeper step stamping part can also generate wrinkling, and the wrinkling surface is required to be polished and treated later. The process stability is poor, the production efficiency is low, the production period is long, the procedures are multiple, the yield is low, and the production cost is greatly increased. With the increase of varieties and yield of deep-step stainless steel stamping parts, the processing of the deep-step stainless steel stamping parts by the traditional double-action stamping technology has become a stainless steel stamping part production bottleneck, and the smooth completion of stainless steel stamping part production tasks is seriously affected.
Patent application with the publication number of CN101406917A and named as a universal drawing die of a single-acting and double-acting press, comprises a female die shared by the single-acting and double-acting drawing dies and a male die assembled in a die cavity of a blank holder. A male die connecting plate connected with a sliding block in a press is arranged at the free end of the male die, the male die connecting plate is detachable, a blank holder backing plate is connected to the end face of the blank holder, a mounting hole for mounting a side pin is arranged on the side face of the blank holder, and a push rod hole for assembling a push rod is arranged on the blank holder backing plate on the inner side face symmetrical to the mounting hole. This patent application, although capable of stamping, still fails to solve the problem of parts getting stuck on the steps during deep step processing.
