Flanging and hole-flanging die for automobile partitions

Abstract

The invention relates to a flanging and hole-flanging die for automobile partitions. The flanging and hole-flanging die comprises an upper die seat, a lower die seat, outer guide columns, inner guide columns, a hole flanging male die, flanging male dies, a male and female die unit and a top die unit. The upper die seat is arranged on the lower die seat through the outer guide columns, a male die backing plate is arranged in the middle of the lower die seat, the hole flanging male die and the flanging male dies are arranged on the male die backing plate through a male die fixing plate, the male and female die unit is arranged between the flanging male die and the upper seat, and the bottom of the lower die seat is provided with the top die unit. Compared with the prior art, the flanging and hole-flanging die is compact in structure and capable of effectively saving occupation space; by the aid of limit columns, positioning pins and the inner guide columns, positioning accuracy of the partitions is effectively improved, flanging height uniformity is ensured, size stability is guaranteed, product processing quality is improved, successive assembly continuity is guaranteed, and the flanging and hole-flanging die is high in operation efficiency and practicality.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and relates to a mold, in particular to a mold for flanging and turning holes of automobile clapboards. Background technique [0002] During the processing of automobile partitions, hole turning and flanging processes are often used. This process is mainly to punch the hole edge or outer edge of the blank into a vertical edge structure under the action of the mold. According to the edge state and stress and strain state of the blank, the flanging can be divided into inner hole flanging and outer edge flanging, and can also be divided into elongation flanging and compression flanging. However, the traditional hole-turning and flanging process is often positioned according to the edge of the partition. In this way, the positioning accuracy of the partition is not enough, resulting in poor product processing consistency. , the gaps between the two are inconsistent, and the subseque...

Problems solved by technology

However, the traditional hole-turning and flanging process is often positioned according to the edge of the partition. In this way, the positioning accuracy of the partition is not enough, resulting in poor product processing consistency. , the gaps between the two are inconsistent, and the subsequent assembly is difficult, which will directly affect the quality of the product and cause huge losses to the production of the enterprise.
