Forming and flanging die for U-shaped support frame of automobile

Abstract

The invention relates to a forming and flanging die for a U-shaped support frame of an automobile, which comprises an upper die part and a lower die part, wherein the upper die part comprises a die handle, an upper die base, an upper cushion plate, a forming concave die, a flanging convex die, guide sleeves, fixed screws, fixed pins and a square pin; two guide sleeve mounting holes are formed in the left side and the right side in the front of the upper die base; a die handle mounting hole, four countersunk head fixed screw holes and two fixed pin holes are formed in the middle of the upper die base; the lower die part comprises a lower die base, a lower die cushion plate, a lower die, guide posts, a positioning pin, fixed screws and fixed pins; two guide post mounting holes are formed in the left side and the right side in the front of the lower die base; four countersunk head mounting holes connected with the lower die cushion plate and two fixed pin holes connected with the lower die cushion plate are formed in the middle of the lower die base; a lower die base mounting screw hole is formed in the lower part of the lower die cushion plate; a flanging concave die hole is formed in the middle of the lower die cushion plate; and in addition, a square groove hole is formed in the upper part of the lower die cushion plate. The forming and flanging die has the benefit that the forming and flanging process of the U-shaped support frame can be finished at one step by the forming and flanging composite die.

Description

technical field [0001] The invention relates to a mold used in the manufacture and molding of auto parts, in particular to a mold for forming and flanging U-shaped brackets of automobiles. Background technique [0002] At present, the forming of the two sides of the automobile U-shaped bracket and the flanging in the middle are carried out separately by hand. The workpiece is clamped with a vise. Because the material is thin, when the vise is clamped, the material is deformed, so that the dimensions of the forming and flanging are inconsistent. High rework rate and low efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of prior art and provide a kind of automobile U-shaped bracket forming flanging mold, it can make forming, flanging compound mold can finish U-shaped bracket forming, flanging process once. [0004] The technical proposal of the present invention is: the automobile U-shaped brack...
