Go out various car brands, traditionally typically all take the material according to automobile metal structural member for various automobile metal structural members
Sheet Metal Forming Technology is worked out in characteristic and shape facility, the requirement being molded according to material, and metal stamping die is made according to Sheet Metal Forming Technology,
To raw material shaping with the automobile metal structural member needed for obtaining on mould.
It is automobile exhaust pipe to have a kind of part in automobile metal structural member, and it is made with hollow steel tube profile,
Its shape and structure includes the larger bending of radius and the larger bending shape of angle.At present, the tubing wall of blast pipe is made
Thickness rate is relatively thin, and during tube stamping shaping is carried out, tubing occurs deformation, especially when tubing carries out wide-angle bending
When, tubing occurs the phenomenon that tubing is flattened often after being subject to stamping pressure.
The content of the invention
It is the defect for having technology on overcoming, the purpose of the present invention proposes to contribute to keep tubing material during tubing bend pipe punching press
The tool itself not being flattened.
To achieve the above object, the present invention is using following technical scheme：
A kind of bend pipe auxiliary fixture, including spherical support block, pillar support block and connector, wherein spherical support block and cylindricality branch
The both sides of bracer are provided with the ear muff for connecting, and are fixed using connector between ear muff.
Further：Buffer layer is enclosed with the outer surface of the spherical support block and the pillar support block.
Further：The buffer layer is made up of yielding rubber block.
Further：The raw material that the yielding rubber block includes following weight portion is made：Natural rubber 90 parts~100
Part, 6 parts~10 parts of zinc oxide, 1 part~2 parts of stearic acid, acceterator TE are 1 part~2 parts, sulphur 2 parts~2.5
Part, antioxidant 4020 are 2.5 parts~3 parts, 35 parts~45 parts of carbon black.
Further：The raw material that the yielding rubber block includes following weight portion is made：90 kilograms of natural rubber, oxidation
6 kilograms of zinc, 1 kilogram of stearic acid, acceterator TE are 1 kilogram, 2 kilograms of sulphur, antioxidant 4020 are 2.5 kilograms, carbon black
35 kilograms, 0.2 kilogram of rubber eliminating smell agent.
Further：The raw material that the yielding rubber block includes following weight portion is made：100 kilograms of natural rubber, oxidation
10 kilograms of zinc, 2 kilograms of stearic acid, acceterator TE are 2 kilograms, 2.5 kilograms of sulphur, antioxidant 4020 are 3 kilograms, charcoal
Black 45 kilograms, 0.3 kilogram of rubber eliminating smell agent.
Because above-mentioned technical proposal is used, the present invention has following advantages：
The auxiliary fixture that the present invention is provided is put into the tubing for need punching press and can effectively prevent tube stamping from deforming, and improves
The success rate of tube stamping；It is easy to use and this tool can be combined according to actual conditions and use.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In the figures above：1st, spherical support block；2nd, pillar support block；3rd, connector.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment：It is shown in Figure 1：
A kind of bend pipe auxiliary fixture, including spherical support block 1, pillar support block 2 and connector 3, wherein spherical support block 1 and post
The both sides of shape support block 2 are provided with the ear muff for connecting, and are fixed using connector 3 between ear muff.Can from Fig. 1
To find out, positioned at the fixed block of the equal semicircular in shape structure of the ear muff of spherical support block 1 and pillar support block 2, it is provided with logical
Hole；And it is monaural set that the ear muff is located at the side of spherical support block 1 and pillar support block 2, opposite side is ears set, monaural set with
Can be cooperated between ears set, and monaural is covered with connector 3 and be located by connecting with ears set.
In actual punching course, although will not deform when can make bending tube forming using above-mentioned bend pipe auxiliary fixture,
But spherical support block and pillar support block and the inwall directly contact of tubing, produce rigidity extruding so that pipe in punching course
Material inner wall abrasion is serious.Therefore, buffer layer is enclosed with the outer surface of the spherical support block and the pillar support block,
The buffer layer is made up of yielding rubber block, can effectively slow down the punching press intensity of tubing and this tool.
The auxiliary fixture that the present invention is provided is put into the tubing for need punching press and can effectively prevent tube stamping from deforming,
Improve the success rate of tube stamping；It is easy to use and this tool can be combined according to actual conditions and use.
