Description
Technical field
The invention belongs to field of machining, more particularly, to a kind of double-fold punching mechanism.
Background technique
In mechanical manufacturing field, the appearance that four-door two-lid is belonged to body of a motor car is needed to open in automobile board manufacturing process
Part is opened, rounding off and uniform fit-up gap are kept with surrounding components after assembly, to reach good interchangeability and vision
Appearance.It needs bound edge to press after the inside and outside plate welding assembly erection welding of back door, is the key that in all kinds of automotive back door productions
Process.Currently, pre- flange is usually taken for the bound edge process of automobile opening tool, same two side edgefold of plate needs to carry out twice
Flanging process, has a disadvantage in that: needing to be realized by two molds, die cost is high, and production efficiency is low.
It is carried out in process treatment process to mechanical plate, needs to carry out trimming, flanging and shaping process to mechanical plate,
Existing bead cutter, a lot of processes need manually to carry out, if the positioning of product is placed, trimming shaping etc..It not only imitates in this way
Rate is low, and due to directly contacting mechanical plate during manual operation, the safety of operation be cannot be guaranteed, and is easy to increase
Add the fraction defective of mechanical plate；In addition, be positioned manually, trimming or flanging are also easy to cause the side of mechanical plate inconsistent, slow down
The speed of production of mechanical plate finished product, the quality of production for reducing mechanical plate.Simultaneously plate need in process
Pressing Deformation is carried out using stamping die, and then obtains effective semi-finished product, in the prior art, when stamped workpieces, due to punching
Head quick washing, will cause workpiece and relative displacement occurs for stamping die, to cause roughness of machining surface, unbalance stress can be made
It is rotated at workpiece, workpiece punch process is caused to make mistakes, waste material, cost of idleness, and formed punch is located at the middle position of workpiece.
So carrying out efficiently bilateral flanging how by simple and mechanical mechanism and equipment to board and handling, producing
Production cost is reduced in journey, and guarantees that board will not occur relatively due to stamping press workpiece and stamping die in punching course
The problems such as displacement is technical problem in the prior art.
Summary of the invention
In view of this, the present invention is directed to propose a kind of double-fold punching mechanism, solves through simple and mechanical mechanism and sets
