Description

Continuous die cutting edge bending mechanism Technical Field The utility model relates to the field of vehicle zero processing equipment, in particular to a continuous die-cutting edge bending mechanism. Background The axle support reinforcing plate is a key structural member in a vehicle suspension system, and a manufacturer uses a die to manufacture the plate into the axle support reinforcing plate by adopting a stamping forming process. In the current processing procedure, the plate is firstly bent in a bending die, and then the plate is fed into a blanking die for cutting. But two dies are needed for processing, the processing time is long, and the production efficiency can not meet the requirement of mass production. It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art. Disclosure of utility model Aiming at the defects of the prior art, the utility model discloses a continuous die-cutting edge bending mechanism. The technical scheme adopted by the utility model is as follows: The continuous die cutting edge bending mechanism comprises a base, a lower die and an upper die, wherein the lower die is arranged on the base, the upper die is movably arranged above the lower die, the lower die comprises a lower die holder and a lower die block, the lower die holder is arranged on the base, a first cutter and a second cutter are arranged at the top of the lower die holder, the lower die block is arranged at the top of the lower die holder, a pair of first protruding parts are arranged at the top of the lower die block, a cavity is formed between the first protruding parts, the upper die comprises an upper die block, a second protruding part is arranged at the bottom of the upper die block, and when the lower die and the upper die are clamped, the second protruding part is inserted into the cavity between the first protruding parts. Further, the top of the first protruding part is a plane, the height of the first protruding part is higher than the top surface of the lower module, and the inner side surface of the first protruding part is an inclined surface. Further, the outer side surface of the second protruding portion is provided with an inclined surface, and the inclined angle of the outer side surface of the second protruding portion is the same as that of the inner side surface of the first protruding portion. Further, the first cutter and the second cutter are arranged in the middle of the lower die holder, and the cutter heads of the first cutter and the second cutter extend into a gap between the lower die blocks. Further, the heights of the tops of the first cutter and the second cutter do not exceed the thickness of the lower module. Further, a pair of limiting modules are arranged on the base, and the limiting modules are vertically arranged on the left side and the right side of the top surface of the base. Further, a clamping groove is formed between the limiting module and the lower die holder. Further, the upper part of the clamping groove is wider than the lower part thereof. The beneficial effects of the utility model are as follows: 1. In the process of preparing the axle supporting reinforcing plate, a material is placed into a lower die, then a press is started to drive an upper die to move downwards, the upper die and the lower die are clamped, the upper die and the lower die act on the material, the material is bent after being pressed, then the upper die moves downwards along with the further bending, then the middle part of the material is contacted with a first cutter and a second cutter, the material is cut off, bending and cutting operations are completed in one procedure, the processing time is greatly shortened, and the working efficiency is improved. 2.
