A manufacturing process of automobile oil pipe fittings

Abstract

The invention relates to a manufacturing process of automobile oil pipe fittings, which uses a surface cleaning equipment, the surface cleaning equipment includes a mounting frame, a support seat, a positioning device and a cleaning device, and the above-mentioned surface cleaning equipment is used to manufacture and process automobile oil pipe fittings The specific process flow is as follows: mold design, casting molding, finishing, surface cleaning and spraying treatment. The positioning device in the present invention positions the two ends of the oil pipe fittings by means of internal support, which facilitates cleaning of the outer wall of the pipe fittings by the cleaning device. Partial and straight pipe parts are cleaned, which can reduce the possibility of cleaning dead angles and ensure the cleaning effect, and the position of the support seat for installing the positioning device and the cleaning device can be adapted according to the bending angle and length of the oil pipe fittings Adjustment can be applied to pipe fittings of various specifications, which expands the scope of application of the present invention.

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 angles when the pipe fittings are sprayed with anti-corrosion later. 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
