The mould comprises an elbow pipe wheel mould which guides the deformation direction of the elbow pipe, an elbow pipe clamp mould and an elbow pipe material clamp, wherein one end of a metal pipe is positioned between the elbow pipe wheel mould and the elbow pipe clamp mould, the other end of the metal pipe is fixed by the elbow pipe material clamp, two sides of the metal pipe are further respectively provided with an elbow pipe guide mould and an elbow pipe anti-wrinkling mould for clamping the metal pipe, the elbow pipe wheel mould and the elbow pipe anti-wrinkling mould are positioned at the inner side of the metal pipe, the elbow pipe clamp mould and the elbow pipe guide mould are positioned at the outer side of the metal pipe, the elbow pipe wheel mould, the elbow pipe clamp mould, the elbow pipe guide mould and the elbow pipe anti-wrinkling mould are all provided cambered surfaces matched with the metal pipe, the elbow pipe anti-wrinkling mould is matched with the cambered surface of the elbow pipe wheel mould, and the metal pipe is internally provided with an elbow pipe core rod for supporting. The mould is simple in structure, the elbow pipe can be prevented from being fractured, sunken and wrinkled, the manufacture reject ratio of the elbow pipe is reduced, the quality of an external pipe of the elbow pipe is improved, and the mould is low in cost and suitable for the existing mould.
Description
Technical field
The utility model relates to the bend pipe processing of air conditioning for automobiles pipeline, especially a kind of anti-bend pipe wrinkling mould that subsides.
Background technology
Usually metal tube adds man-hour at bend pipe, does not support because the bending section tube chamber is inner, and inner chamber very easily produces and subsides when crooked deformation, and the tube intracavity valid circulation area is diminished, and the bend loss inboard that has also can produce wrinkle.It is serious more to subside for the thin more pipe fitting of tube wall, and intracavity section is long-pending also more little, and this will have influence on the proper flow of tube fluid, and affect indirectly the overall performance of component system, and Jia Gong yield rate also decreases simultaneously.Usually, the bend pipe zone external diameter deflection that the automobile industry pipe part allows is no more than 15%, some high-end products even require external diameter deflection≤10%.In recent years, along with the raising of material property, for reducing material consumption, the use of thin-wall pipes constantly increases, and the processing of light-wall pipe is the difficult problem of puzzlement enterprise always.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of anti-bend pipe wrinkling mould that subsides is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of anti-bend pipe wrinkling mould that subsides, the bend wheel mould that comprises guiding bend pipe deformation direction, bend pipe clamping and bend pipe feed collet, one end of metal tube is between bend wheel mould and bend pipe clamping, the other end is fixed by the bend pipe feed collet, the both sides of metal tube also are provided with bend pipe guided mode and the wrinkle resistant mould of bend pipe that is used to clamp metal tube, the wrinkle resistant mould of bend wheel mould and bend pipe is positioned at the inboard of metal tube, bend pipe clamping and bend pipe guided mode are positioned at the outside of metal tube, bend wheel mould, the bend pipe clamping, the wrinkle resistant mould of bend pipe guided mode and bend pipe all has the cambered surface that matches with metal tube, the cambered surface of wrinkle resistant mould of bend pipe and bend wheel mould matches, and is provided with the bend pipe plug that is used to support in the metal tube.
The beneficial effects of the utility model are: the utility model is simple in structure, can prevent bend pipe break, subside, wrinkling, reduce bend pipe processing fraction defective, improve the quality of pipe fitting outer tube, cost is low, is applicable to existing mold.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a working state schematic representation of the present utility model.
Among the figure: 1. bend wheel mould, 2. bend pipe clamping, 3. bend pipe feed collet, 4. metal tube, 41. bend pipe plugs, 5. bend pipe guided mode, the 6. wrinkle resistant mould of bend pipe.
The specific embodiment
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
The wrinkling mould that subsides of anti-bend pipe as shown in Figure 1, the bend wheel mould 1 that comprises guiding bend pipe deformation direction, bend pipe clamping 2 and bend pipe feed collet 3, one end of metal tube 4 is between bend wheel mould 1 and bend pipe clamping 2, the other end is fixing by bend pipe feed collet 3, the both sides of metal tube 4 also are provided with bend pipe guided mode 5 and the wrinkle resistant mould 6 of bend pipe that is used to clamp metal tube 4, bend wheel mould 1 and the wrinkle resistant mould 6 of bend pipe are positioned at the inboard of metal tube 4, bend pipe clamping 2 and bend pipe guided mode 5 are positioned at the outside of metal tube 4, bend wheel mould 1, bend pipe clamping 2, the wrinkle resistant mould 6 of bend pipe guided mode 5 and bend pipe all has the cambered surface that matches with metal tube 4, the wrinkle resistant mould 6 of bend pipe matches with the cambered surface of bend wheel mould 1, is provided with the bend pipe plug 41 that is used to support in the metal tube 4.
The wrinkling mould that subsides of anti-bend pipe as shown in Figure 2, elder generation inserts an end of metal tube 4 in the bend pipe feed collet 3 during bend pipe, metal tube 4 clampings are located, start bending machine then and carry out bend pipe processing, during work, bend wheel mould 1, bend pipe clamping 2, the wrinkle resistant mould 6 of bend pipe guided mode 5 and bend pipe clamps metal tube 4, and metal tube 4 profiles are produced and the opposite predeformation of bend pipe collapse-deformation direction, metal tube 4 is along the cambered surface flexural deformation of bend wheel mould 1 and the wrinkle resistant mould 6 of bend pipe, bend pipe clamping 2 and bend pipe guided mode 5 are according to the center of circle motion of bend wheel mould 1, fixing and pressed metal manages 4, under the inner support of bend pipe plug 41, bend wheel mould 1 and bend pipe clamping 2 clamping metal tubes 4 rotoflectors are because the existence of predeformation, offset the deflection that subsides in a part of bend pipe, thereby bending quality is improved.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
