Abstract
The invention discloses a kind of closed torsion beam of car and manufacture new technology, process route is: blanking → drawing → trimming and piercing die → flange → side deburring → side chamfering → molding → welding → cut.The present invention, from raw material, with plate replacement seamless steel pipe as the production raw material of closed torsion beam, fundamentally reduces the production cost of closed torsion beam, and material cost can be reduced to about 50 yuan from about 120 yuan；Moreover, the present invention is effectively increased the production efficiency of product, greatly reduces production equipment cost.
Description
Technical field
The present invention relates to a kind of car closed torsion beam plate shaping technique.
Background technology
At present it is known that the production technology of the closed torsion beam of car have shaped by fluid pressure, thermoforming, cold stamping shaped three
Kind, the raw material of three of the above production technology is seamless steel pipe, and requires higher to the technology of seamless steel pipe, this adds increased
The manufacture difficulty of seamless steel pipe and manufacturing cost, thus cause the cost of raw material of closed torsion beam too high.
Summary of the invention
Because the above-mentioned deficiency of prior art, the technical problem to be solved is to provide a kind of car to close
Formula torsion beam plate shaping technique.
Technical scheme is as follows: a kind of car closed torsion beam plate shaping technique, it is characterised in that include
Following steps:
1) blanking: utilize plate shearing machine to intercept the plate of rectangle from raw material plate；
2) drawing: utilize mould that plate is carried out drawing, makes centrage formation " V " shape groove along its length on plate；
3) trimming and piercing die: utilize trimming and piercing die that four limits of the plate after drawing carry out deburring, and at " V " shape groove two ends
The outside of end forms hole, location；
4) flange: utilize flange die by the two of plate long limits towards same direction flange, form flanging, the flanging on both sides
Form groove, and the notch direction of groove is in opposite direction with the notch of described " V " shape groove；
5) side deburring: utilize side trimming die conduplication side to carry out deburring；
6) side chamfering: utilize side chamfering mould that the flanging after deburring is carried out chamfering, in order to follow-up welding；
7) molding: utilize the semi-finished product punch forming after shaping mould offside chamfering, makes the flanging on both sides towards relative side
To bending, the kink on both sides is stitched together；
8) welding: utilize welding tooling that the splicing seams of the semi-finished product both sides kink after molding is welded, be allowed to into
For closed state；
9) cut: utilize laser cutting device to be excised by excess waste, obtain fabricated part.
As preferably, step 2) to step 7) all carry out on punch press.
As preferably, step 4) to step 9) all use hole, location to position.
Beneficial effect: the present invention, from raw material, substitutes the seamless steel pipe production as closed torsion beam with plate
Raw material, fundamentally reduces the production cost of closed torsion beam, and material cost can be reduced to 50 yuan from about 120 yuan
Left and right；Moreover, the present invention is effectively increased the production efficiency of product, greatly reduces production equipment cost.
Accompanying drawing explanation
Fig. 1 is the technical process schematic diagram of closed torsion beam.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
As it is shown in figure 1, the plate shaping technique of the closed torsion beam of car, comprise the steps of:
1) blanking: utilizing plate shearing machine to intercept the plate 1 of rectangle from raw material plate, raw material plate is preferably high-strength steel sheet, plate
Thickness determines according to actual needs；The length direction of plate 1 is left and right directions, and width is fore-and-aft direction；
2) drawing: utilize mould that plate 1 is carried out drawing on punch press, makes on plate 1 center along its length linear
Becoming " V " shape groove 2, the end of " V " shape groove 2 is near the edge of plate 1 corresponding end, and the degree of depth of " V " shape groove 2 is from the side at middle past two ends
To tapering into；
3) trimming and piercing die: utilize trimming and piercing die that four limits of the plate 1 after drawing are carried out deburring on punch press, make plate
The limit, left and right of 1 is straight flange, and front and rear side is round and smooth；And hole 3, location, hole, two location 3 and " V " is formed at the two ends, left and right of plate 1
The both ends one_to_one corresponding of shape groove 2, and hole 3, location is positioned at the outside of " V " shape groove 2 end；
4) flange: utilize flange die by two long limits of plate 1 towards same direction flange on punch press, form flanging 4,
The flanging 4 on both sides forms groove, and the notch direction of groove is in opposite direction with the notch of " V " shape groove 2；This operation utilizes hole, location
3 position, and the angle of flange determines according to actual needs, and the present embodiment is preferably 60 °.
5) side deburring: utilize hole 3, location to position on punch press, and utilize side trimming die conduplication side 4 to carry out deburring, make
The edge circular arc of flanging 4；
6) side chamfering: utilize hole 3, location to position on punch press, and utilize side chamfering mould that the flanging 4 after deburring is entered
Row chamfering, in order to follow-up welding；
7) molding: utilize hole 3, location to position on punch press, and utilize the semi-finished product punching press after shaping mould offside chamfering
Molding, forms the finished product blank identical with fabricated part moulding, and the flanging 4 on both sides is towards relative direction bending, both sides
Kink 5 is stitched together；
8) welding: utilize welding tooling that the splicing seams of the semi-finished product both sides kink 5 after molding is welded, be allowed to into
For closed state；This operation uses hole 3, location to position；
9) cut: utilize laser cutting device to be excised by excess waste, obtain fabricated part；This operation is also adopted by fixed
Hole 3, position positions.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art without
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technology in the art
Personnel are available by logical analysis, reasoning, or a limited experiment the most on the basis of existing technology
Technical scheme, all should be in the protection domain being defined in the patent claims.
