Car oil way pipe fitting manufacturing and machining process

Abstract

The invention relates to a car oil way pipe fitting manufacturing and machining process. Surface cleaning equipment is adopted, and comprises a mounting rack, a supporting seat, a positioning device and a cleaning device. The specific technological process of adopting the surface cleaning equipment for manufacturing and machining a car oil way pipe fitting comprises the following steps of mold designing, cast molding, finish machining, surface cleaning and spraying treatment. The two ends of the oil way pipe fitting are positioned through the positioning device in an internal supporting manner, the outer wall of the pipe fitting can be cleaned conveniently through the cleaning device, the bent pipe portion and the straight pipe portion of the pipe fitting can be specifically cleaned through a straight pipe cleaning brush and a bent pipe cleaning brush in the cleaning process, the probability that a cleaning dead corner exists can be reduced, and the cleaning effect is guaranteed; the position of the supporting seat where the positioning device and the cleaning device are mounted can be adaptively adjusted according to the bending angle size and length size of the oil way pipe fitting, the supporting seat can be suitable for pipe fittings of multiple specifications, and the application range of the surface cleaning equipment is widened.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to a manufacturing and processing technology of automobile oil pipe fittings. Background technique [0002] Automobile oil circuit usually includes two types: the engine oil circuit and the fuel oil circuit of the car. The oil circuit refers to the way inside the engine, and the oil runs through the oil pump. The fuel oil circuit is also called the fuel system. The pipe from the fuel tank to the combustion chamber of the engine. The fuel oil circuit includes: fuel filter, gasoline pump, fuel pressure regulating valve, gasoline pipe fittings, fuel injectors, etc. [0003] Most of the gasoline pipe fittings used in the fuel oil circuit are bent pipes. The manufacturing process of such gasoline pipe fittings usually includes steps such as casting, surface grinding, surface cleaning and anti-corrosion treatment. In the process of surface cleaning The following prob...

Problems solved by technology

[0004] (1) Before the cleaning work starts, fixtures are usually used to position the pipe fittings. Since the bending angles of the pipe fittings are different and the adjustment range of the fixtures is limited, it is necessary to configure various types of fixtures for selection in advance, which increases the manufacturer's cost. The purchase cost, and the time spent on the selection and replacement of fixtures will delay the progress of the overall work;

[0005] (2) The pipe fittings consist of straight pipes and curved pipes. During the cleaning process, it is difficult for the cleaning tool to fully contact with all parts of the curved pipes, and it is easy to appear cleaning dead angles, which leads to the comparison of the spraying effect of the cleaning dead corners when the pipe fittings are sprayed with anti-corrosion. It is not ideal for other parts, and the dead corners are prone to corrosion during the use of the pipe fittings, which reduces the overall service life of the pipe fittings
