A manufacturing process of automobile oil pipe joints

Abstract

The invention relates to a manufacturing process of automobile oil circuit pipe fittings, which uses a core removal device, the core removal device includes a mounting frame, a removal device and a fixing device, and the above core removal device is used to manufacture and process the automobile oil circuit The specific process of pipe fittings is as follows: equipment adjustment, joint fixing, core crushing, joint removal and debris cleaning. frame, connecting straight rod, rotating cam, driving bevel gear, driving motor and driven bevel gear. The invention fixes the joints through the fixing device to cooperate with the clearing device to complete the core removal operation. During the removal process, the needle-type tamping rod can not only rotate and crush the core, but also perform up and down crushing operations, effectively The removal efficiency is improved, and the fixing device can drive the joint to vibrate at the same time, which is beneficial to the discharge of core debris.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a manufacturing process of an auto oil pipe joint. 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] The gasoline pipe fittings used in the fuel oil circuit are mostly bent pipes, and the bending angle is mostly 90 degrees. The gasoline pipe fittings with a bending angle of 90 degrees are mostly produced by sand casting. Finally, tools are needed to remove the core in the casting cavity. [0004] At present, the cleaning ...

AI Technical Summary

Problems solved by technology

[0005] (1) When cleaning by drum cleaning, shot blasting, etc., it is necessary to put the pipe fittings into the equipment as a whole, and rely on the friction between castings, waste sand and star iron or steel shots to achieve the purpose of cleaning. During the working process, The surface of pipe fitting joints is prone to defects such as scratches and cracks due to bumping, which reduces the appearance quality and service life of pipe fitting joints;

[0006] (2) Since the pipe fitting joint consists of two parts, the straight pipe and the elbow pipe, and it is difficult to fully contact the elbow of the pipe fitting joint with the cleaning tool during the cleaning process, the core attached to the inner wall of the elbow pipe cannot be completely detached and remains on the inner wall of the elbow pipe Part of the core on the pipe will hinder the normal flow of fuel in the pipe joint, which will affect the normal use of the fuel oil circuit
