Automobile exhaust pipe manufacture welding treatment process

Abstract

The invention relates to an automobile exhaust pipe manufacture welding treatment process. A bottom plate, a bearing and containing device, polishing devices and a regulation device are included. Thebearing and containing device is installed at the upper end of the bottom plate. The polishing devices are symmetrically arranged in the middle of the bearing and containing device. The polishing devices are connected with the bearing and containing device in a sliding fit manner. The automobile exhaust pipe manufacture welding treatment process can solve the problem that when an existing device conducts cleaning for weld beadings generated during welding of silencers in automobile exhaust pipes and connection pipes, angle regulation cannot be conducted during polishing, the situation that thedevice cannot be perfectly matched with the weld beadings is likely to be caused, and therefore removal of the weld beadings is not complete and the polishing effect is reduced, the problem that dueto the fact that the two connection pipes cannot be cleaned at the same time, the polishing efficiency is reduced and the problem that due to the fact that weld beadings generated on the other placesof the surfaces of the connection pipes cannot be removed under the condition of not changing the positions of the connection pipes, the weld beading polishing steps are increased and the polishing efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of exhaust pipe welding, in particular to a manufacturing and welding process for automobile exhaust pipes. Background technique [0002] The automobile exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter for controlling the emission of engine pollutants is also installed in the exhaust system. The trachea generally includes a front exhaust pipe and a rear exhaust pipe, and its main material is stainless steel SUS304. The exhaust pipe mainly plays the role of shock absorption and noise reduction for the car body, and prolongs the life of the exhaust muffler system. [0003] At present, when the existing welding welds produced during the welding of the muffler and the connecting pipe in the automobile exhaust pipe are cleaned, there are usually the following deficiencies: ...

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment cannot adjust the angle during grinding when cleaning the welding spatula generated during the welding of the muffler and the connecting pipe in the automobile exhaust pipe, and it is easy to cause the equipment to be unable to perfectly cooperate with the spatula. As a result, the removal of the welding spar is not clean, which reduces the effe
