Punch forming die for middle channels of left and right parts of automobile A column

Abstract

The invention relates to a punch forming die for middle channels of left and right parts of an automobile A column. The punch forming die is good in forming effect and not prone to cracking, the punch forming die comprises an upper die base and a lower die base, an upper pressing block, a rectangular punch and a through hole punch are arranged in the upper die base through a plurality of nitrogen springs, and an upper end cutter block, an upper connecting portion cutter block and an upper shape follow-up block are arranged on the upper die base and located on the outer edge of a groove opening of a mounting groove, and a wedge driving block is arranged on the upper die base; a lower forming block is arranged on the lower die base, a forming face is arranged on the lower forming block, two notches which are arranged side by side are formed in the outer edge, close to the short edge, of the long edge corresponding to the workpiece, of the lower forming block, cutting edge parts matched with the upper end cutter block and the upper connecting part cutter block are arranged on the lower forming block, and a rectangular die button and a through hole die button are arranged on the lower forming block. A sliding guide block is arranged on the lower die base, a side forming base for forming the position, needing to be flanged, of a triangular area at the end of the long edge of the workpiece is movably arranged on the sliding guide block, and a driving inclined face matched with the wedge driving block is arranged on the side forming base.

Description

technical field [0001] The invention relates to a stamping mold for the middle channel of the left and right parts of the A-pillar of an automobile. Background technique [0002] Automobile A-pillar left and right parts such as figure 1 As shown, when the two are combined for stamping, since the workpiece is roughly L-shaped, the left and right workpieces are arranged symmetrically during the combined stamping, and the two long sides are arranged side by side. The center side needs to be cut off, while the other side of the triangular area needs to be turned over; the rest of the edge of the workpiece needs to be turned over, except for the short side end and the long side near the triangular side. Edge processing.

AI Technical Summary

Problems solved by technology

[0003] When stamping the middle of the left and right parts of the A-pillar, it is necessary to complete the general shape of the left and right parts, flanging the other side of the triangular area of ​​the workpiece, flanging the edge of the workpiece away from the symmetrical line of the workpiece, and punching some holes; However, due to the complex shape of the workpiece, the processing is difficult, and the stamping is easy to twist and crack
