Forming and machining method for automobile air-conditioning pipeline connection metal joint

Abstract

The invention relates to the field of auto spare part machining, in particular to a forming and machining method for an automobile air-conditioning pipeline connection metal joint. A forming and machining device is used in the forming and machining method. The forming and machining device comprises a fixed base and an adjusting base. The adjusting base comprises a first module, a second module anda third module. The first module and the second module are symmetrically arranged. First hydraulic cylinders are symmetrically and fixedly connected into the first module. Output ends of the first hydraulic cylinders are each fixedly connected to one side of the second module. The top of the first module and the top of the second module are symmetrically provided with grooves. The third module isinserted in the grooves. The bottom of each groove is symmetrically provided with connecting grooves. The bottom of the third module is symmetrically fixedly connected with connecting columns. The connecting columns are inserted in the symmetrical connecting grooves and are slidingly connected with the connecting grooves correspondingly. The forming and machining method is simple in structure, easy to operate and suitable for popularization and can perform fixed-point and fixed-direction bending on the connection metal joint.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a method for forming and processing metal joints connected to automobile air-conditioning pipelines. Background technique [0002] Auto parts are used in various parts of the car, which is an integral part of the car. Air conditioners are usually installed in the car, and the installation of the air conditioner requires the installation of air-conditioning pipelines, and metal joints are needed to connect the air-conditioning pipelines. [0003] Metal joints are generally shaped during production and processing, and most of them are straight pipes. In the installation process of automobile air conditioners, elbow metal joints are often used to connect air-conditioning pipes. The bending angle of these elbows is usually not Consistent, this requires manual bending, but manual bending cannot ensure the accuracy of the bending angle, which will affect the connection of the air c...

[0003] Metal joints are generally shaped during production and processing, and most of them are straight pipes. In the installation process of automobile air conditioners, elbow metal joints are often used to connect air-conditioning pipes. The bending angle of these elbows is usually not Consistent, this requires manual bending, but manual bending cannot ensure the accuracy of the bending angle, which will affect the connection of the air conditioning pipeline. At the same time, manual bending will cause deformation of the metal joints, affecting the function of the metal joints, resulting in Blockage of air conditioning pipes
