Abstract
Torsion beam buffer stopper limit base cold punching technology after a kind of CS9, it is characterized in that by blanking, blanking, punching, preform, forming, punching step.No longer occurring cracking phenomena at workpiece bottom roundings, product qualification rate significantly improves, easy and safe to operate, and it is high production efficiency, at low cost, have and promotes quotability.
Description
Technical field
The present invention relates to a kind of metal parts processing technology, torsion beam buffer stopper limit base cold punching after especially a kind of CS9
Pressure technique.
Background technique
Torsion beam buffer stopper limit base is in band edge U-shaped structure after existing, has a circular hole, flange among this structural base
Line of symmetry on there are two semi-circular hole, be the circular hole first gone out among bottom of a cup, re-drawing is turned over according to conventional production method
Side and two, punching edge semi-circular hole, since drawing is uneven, circular hole is easily-deformable among bottom of a cup, secondly R circle at bottom of a cup drawing
Easily there is cracking phenomena in angle, and product qualification rate is low, and production efficiency is low, at high cost.
Summary of the invention
The purpose of the invention is to overcome the above-mentioned shortcoming of the prior art, and a kind of product qualification rate height is provided,
It is easy to operate, torsion beam buffer stopper limit base cold punching technology after high production efficiency, CS9 at low cost.
For achieving the above object, the concrete technology method that the present invention uses is by following steps:
1. blanking: according to the Design spreading size of workpiece, plate being cut into billot or block on plate shearing machine；
2. blanking, punching: designing and producing dedicated blanking, punching die, on punching machine or hydraulic press, carry out punching work to workpiece
Skill hole and blanking processing；
3. preform: to round corner machining is carried out at U-shaped part bottom transition, rounding angle value is R5, designs and produces dedicated U-shaped part
Shaping dies carries out preform processing to the workpiece of blanking, punching on punching machine or hydraulic press；
4. forming: special forming mould tool is designed and produced, on punching machine or hydraulic press, processing is formed to preformed workpiece:
5. punching: designing and producing Special punching punch die, on punching machine or hydraulic press, rush circular hole and two sides half among U-shaped part bottom
Round hole.
No longer there is cracking phenomena, product qualification rate at workpiece bottom roundings due to using process above method in the present invention
It significantly improves, it is easy and safe to operate, it is high production efficiency, at low cost, have and promotes quotability.
Specific embodiment
1. plate is cut into billot or block on plate shearing machine according to the Design spreading size of workpiece；
2. designing and producing dedicated blanking, punching die, on punching machine or hydraulic press, flushing technology hole is carried out to workpiece and is fallen
Material processing；
3. carrying out round corner machining at pair U-shaped part bottom transition, rounding angle value is R5, designs and produces dedicated U-shaped part finishing die
Tool carries out preform processing to the workpiece of blanking, punching on punching machine or hydraulic press；
4. designing and producing special forming mould tool, on punching machine or hydraulic press, processing is formed to preformed workpiece:
5. designing and producing Special punching punch die, on punching machine or hydraulic press, it is semicircle to rush circular hole and two sides among U-shaped part bottom
Hole.
