Abstract
The utility model discloses a flange with a limiting step. The flange comprises a flange, wherein the flange is an annular element, a limiting circular truncated cone is arranged on the rear end of the flange, the limiting circular truncated cone is in an annular structure, and the flange and the limiting circular truncated cone are in an integral structure. The flange disclosed by the utility model can guarantee the depth of a pipe fitting inserted in the flange to meet the application demand and solve the problem of insufficient insertion quantity or out of tolerance, so as to improve the product quality, reduce the raw material waste and save the cost.
Description
Technical field
The utility model relates to the automobile exhaust system field, particularly a kind of flange that has limited step.
Background technique
At present the attachment hole major part with the flange of pipe fitting seam all is a through-hole structure, behind the pipe fitting insertion flange, again with flange with pipe fitting solid welding be in the same place.
In welding process, because attachment hole is a through-hole structure, the degree of depth that pipe fitting inserts flange is difficult to control, very easily causes insertion depth not enough or overproof, even leans out the situation of Flange Plane.
Therefore,, reality is sought after a kind of orientation type that can simple and easy assurance pipe fitting insertion depth in producing.
The model utility content
The purpose of the utility model provides a kind of flange that has limited step, and this novel flange arrangement guarantees that the degree of depth of pipe fitting insertion flange satisfies usage requirement, solves quantity not sufficient or the overproof problem inserted simultaneously.
The technological scheme that adopts is:
A kind of flange that has limited step comprises flange, and flange is a ring part, and the rear end of flange is provided with spacing round platform, and in order to the insertion position of restriction outer cannula 2, spacing round platform is a loop configuration, and flange and spacing round platform are an overall structure.
During welding, the front end of outer cannula 2 can guarantee that near round platform the insertion amount meets the demands, and also can not let pipe fitting lean out flange, causes the insertion amount overproof.
The advantage of the utility model is:
The utility model can guarantee that the degree of depth of pipe fitting insertion flange satisfies usage requirement, solves simultaneously and inserts quantity not sufficient or overproof problem, and then improve the quality of products, and reduces waste of raw materials, saves cost.
