Production technology for trim cover of automobile exhaust pipe

Abstract

The invention relates to a production technology for a trim cover of an automobile exhaust pipe. The technology includes the following steps of splitting, cutting, stamping, edge cutting, electric welding, trimming, welding, polishing and packaging. According to the production technology for the trim cover of the automobile exhaust pipe; fixing and assembly are conducted in a welding manner, and floating of a spare part is avoided; the trim cover is firmly fixed; and the service life of the trim cover of the exhaust pipe is prolonged. Three-hole datum plane positioning is adopted; spot welding is conducted firstly, and then welding is conducted; the welding successful rate is increased; it is ensured that the qualification rate of products is 100%; the burden of workers is relieved; the production efficiency is improved; materials are saved; and cost is reduced. The production technology for the trim cover of the automobile exhaust pipe is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a production process of automobile parts and production equipment thereof, in particular to a production process of an automobile exhaust pipe decorative cover. Background technique [0002] The automobile exhaust pipe plays the role of reducing vibration and noise, facilitating installation and prolonging the life of the exhaust muffler system, while the decorative cover of the automobile exhaust pipe plays the role of preventing the deformation and accumulation of water in the exhaust pipe. During the manufacturing process of the pipe decoration cover, the material is first punched on the punching machine to cause plastic deformation to form loose parts. The loose parts are generally connected with screws and screw holes. This connection method will cause the loose parts to float and be fixed unstable. If the exhaust pipe decoration cover is used for a long time, the parts will be severely worn and the life will be reduced. I...

Problems solved by technology

[0002] The automobile exhaust pipe plays the role of reducing vibration and noise, facilitating installation and prolonging the life of the exhaust muffler system, while the decorative cover of the automobile exhaust pipe plays the role of preventing the deformation and accumulation of water in the exhaust pipe. During the manufacturing process of the pipe decoration cover, the material is first punched on the punching machine to cause plastic deformation to form loose parts. The loose parts are generally connected with screws and screw holes. This connection method will cause the loose parts to float and be fixed unstable. If the exhaust pipe decoration cover is used for a long time, the parts will be severely worn and the life will be reduced. In order to avoid the above problems, some manufacturers use direct welding to fix the parts on the fixing frame and then weld them. The exhaust pipe decorative cover manufactured by this method has a long service life, but because the welding part of the exhaust pipe decorative cover parts is curved, the ordinary fixing frame cannot make the welding part without gaps, and the welding is difficult, requiring workers to have higher welding skills and more Great patience, high labor cost and low efficiency, and in the welding process, due to the difficulty of welding itself and the influence of external factors, the welding failure rate is high, defective products are prone to be produced, and the cost of raw materials is high. The above reasons lead to the production connection method being welding The market price of the exhaust pipe decorative cover is high, and it is not easy to promote the product

To sum up, due to the low service life, high cost, low efficiency and high defective rate of exhaust pipe decorative cover, the existing production process needs to be improved
