Abstract
The utility model relates to a flange with a lug boss. The flange comprises a flange sleeve, wherein the flange sleeve comprises a flange sleeve inner ring and a flange sleeve outer ring, the lug boss is integrally arranged on the right end surface of the flange sleeve inner ring, and the lug boss and the flange sleeve inner ring are arranged on the same plane. According to the utility model, the lug boss with a certain height is arranged on the right end surface of the flange sleeve, therefore the flange strength is increased, the influence of welding heat on the flange is lightened and the planeness requirement is met. The flange disclosed by the utility model has the advantages of being capable of resisting deformation generated by welding, saving subsequent machining, reducing manpower, saving cost and further reducing production cost.
Description
Technical field
The utility model belongs to the automobile exhaust system field, particularly a kind of flange that has boss.
Background technique
At present, along with the develop rapidly of automobile industry, people also improve the requirement of automobile day by day, so just need each link technical merit all will improve.
Yet; Main Placement between existing each assembly of automobile exhaust system is that plane face flange connects; Be the planeness requirement≤0.5mm of its junction surface of assurance sealing, and flange is welded on all on the outlet pipe, yielding because of welding; Can not meet the demands, often need following process or school type solve problem.
The model utility content
The purpose of the utility model provides a kind of flange that has boss, and this novel flange can be resisted the distortion that welding produces.
The technological scheme that adopts is:
A kind of flange that has boss comprises the flange cover, and the flange cover comprises flange cover inner ring and flange cover outer ring, and one is equiped with boss on the right side of flange cover inner ring, and boss and flange cover inner ring are arranged on the same plane.
Have the boss of certain altitude on the flange cover right side, both increased strength of flange, also alleviated the influence of welding heat, satisfied the requirement of planeness flange.
Method for using:
Behind connecting tube 5 insertion flange cover inner rings, carry out seam and connect.
The advantage of the utility model is:
The utility model can be resisted the distortion that welding produces, and saves following process, reduces manpower, saves cost, and then reduces production costs.
