Automobile exhaust pipe welding forming post-processing equipment and post-processing method

Abstract

The invention relates to automobile exhaust pipe welding forming post-processing equipment and a post-processing method. The automobile exhaust pipe welding forming post-processing equipment comprises a base, a fixing device and a polishing device, the lower end of the base is connected with the existing ground, and the fixing device and the polishing device are sequentially installed at the upper end of the base from front to back. Through cooperation of fixing rings, limiting bolts and arc-shaped blocks, automobile exhaust pipes can be fixed, the situation that the welded and formed automobile exhaust pipes deviate and shake in the polishing process is avoided, and the distance between the arc-shaped blocks can be adjusted by adjusting the limiting bolts, so that the equipment can fix the exhaust pipes with different diameters, and then the exhaust pipes with different diameters can be polished.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipes, in particular to post-processing equipment and a post-processing method for welding and forming automobile exhaust pipes. Background technique [0002] Automobile, that is, a vehicle that can be driven by its own power and does not need to be erected on tracks or electricity, and can be motorized, and the automobile will be equipped with an exhaust pipe. The exhaust pipe is installed between the engine exhaust manifold and the muffler to make the entire exhaust The system is flexibly connected, so as to reduce vibration and noise, facilitate installation and prolong the life of the exhaust muffler system. The exhaust pipe is mainly used for light vehicles, miniature cars, passenger cars, motorcycles, and the structure of the exhaust pipe is double.

Problems solved by technology

[0002] Automobile, that is, a vehicle that can be driven by its own power and does not need to be erected on tracks or electricity, and can be motorized, and the automobile will be equipped with an exhaust pipe. The exhaust pipe is installed between the engine exhaust manifold and the muffler to make the entire exhaust The system is flexibly connected, so as to reduce vibration and noise, facilitate installation and prolong the life of the exhaust muffler system. The exhaust pipe is mainly used for light vehicles, miniature cars, passenger cars, motorcycles, and the structure of the exhaust pipe is double. The outer layer of the corrugated pipe is covered with a steel wire mesh sleeve, and the straight edge sections at both ends are covered with snap rings. In order to make the noise reduction effect better, the bellows can be equipped with expansion joints or mesh sleeves. The main material of the exhaust pipe is stainless steel. The material of the connecting pipe can be stainless steel or aluminum-plated steel, and the general exhaust pipe is made by welding, but after welding, there will be uneven welding joints, which greatly affects the appearance, so the welding joints need to be polished, etc. , to make it smooth and smooth, but the existing automobile exhaust pipe welding and forming post-processing equipment often encounters the following problems in the process of polishing the exhaust pipe:

[0003] 1. During the grinding process, the exhaust pipe is prone to shift and shake, resulting in poor grinding effect and low grinding efficiency, and the existing equipment can only fix and polish the exhaust pipe with one diameter, so that The utility of the device is not high;

[0004] 2. The existing equipment only uses grinding blocks for first-level grinding during the grinding process, which is easy to cause wear on the exhaust pipe due to excessive grinding, and the grinding waste cannot be effectively and timely disposed of
