Problems solved by technology

[0002]At present, the forming of the two sides of the U-shaped bracket of the car and the flange in the middle are carried out separately by hand, and the workpiece is clamped by a vise. When the material is deformed, so that the size of the forming and flanging is inconsistent, the rework rate is high and the efficiency is low

Embodiment 1

[0014] Such as figure 1 As shown, a precision flanging mold includes an upper mold base 1, a lower mold base 2, a backing plate 3, a lower mold 4, an upper mold 5, and a fixing plate 6; the lower end of the upper mold base 4 is fixedly connected to the backing plate 3 , the lower end of the backing plate 3 is fixedly connected with the upper mold 5; the lower mold base 2 is fixedly connected with the lower mold 4; There are mutually symmetrical flanging grooves 7; the upper die 5 and the lower die 4 are provided with punching protrusions 8.

[0015] Further, the number of the upper mold 5 is two, distributed symmetrically.

[0016] Further, the number of the lower dies 4 is two, and they are distributed symmetrically.

[0017] During operation, the workpiece is placed on the fixed plate 6, and the upper die base 1 is pressed downward by the pneumatic punching machine. When the fixed plate 6 contacts the lower die 4, continue to apply pressure to make the edge punching head ...

Abstract

A precision flanging die comprises an upper die holder, a lower die holder, a backing plate, an upper die, a lower die, and a fixing plate. The lower end of the upper die holder is fixedly connected with the backing plate. The lower end of the backing plate is fixedly connected with the upper die. The lower die holder is connected with the lower die. The fixing plate is connected with the backing plate through an elastic member and bolts. Upper and lower ends of the fixing plate are provided with symmetric flanging grooves. Both the upper die and the lower die are provided with trimming punches. The precision flanging die is capable of finishing flanging once, the technical requirements of products are effectively guaranteed, dimensional stability is ensured, quality is good, and work efficiency is improved; the precision flanging die is simple in structure, simple to operate, low in manufacture cost, good in machining effect, and highly practicable.

Description

technical field [0001] The invention relates to the field of machining, in particular to a precision flanging mold. Background technique [0002] At present, the forming of the two sides of the automobile U-shaped bracket and the flange in the middle are carried out separately by hand. The workpiece is clamped with a vise. Due to the thin material, when the vise is clamped, the material is deformed, so that the dimensions of the forming and flange are inconsistent. High rework rate and low efficiency. Contents of the invention [0003] The technical problem solved by the present invention is to provide a precision flanging mold to solve the problems raised in the above-mentioned background technology. [0004] The technical problem solved by the present invention adopts following technical scheme to realize: [0005] A precision flanging mold, comprising an upper mold base, a lower mold base, a backing plate, a lower mold, an upper mold, and a fixing plate; the lower end...
