Machining process of hydraulic pipe joints

Abstract

The invention provides a machining process of hydraulic pipe joints. The machining process comprises the following steps: a, material preparation: selecting corresponding rod materials according to shapes and sizes of the hydraulic pipe joints; b, material cutting: cutting the materials according to the length sizes of the hydraulic pipe joints and reserving a margin of 0.2mm to 0.3mm in the length direction; c, benchwork: preparing top sharp holes on axial lines of the cut materials and preparing the top sharp holes on the two end surfaces; d, turning machining: performing turning machining and semi-finishing on peripheral parts and reserving a margin of 0.02mm to 0.03mm; e, heat treatment: performing quenching and tempering treatment on workpieces subjected to the semi-finishing; f, turning finishing: machining the peripheral parts and the two end surfaces of the workpieces to the required size; g, linear cutting: performing linear cutting on inner through holes of the workpieces; and h, mirror polishing: performing mirror polishing on outer parts and inner parts of the workpieces. According to the machining process of the hydraulic pipe joints, procedures are arranged reasonablyand properly, the machining precision is high and deformation is difficult to occur.

Description

technical field [0001] The invention relates to a hydraulic pipe joint, in particular to a processing technology of the hydraulic pipe joint. Background technique [0002] The hydraulic pipe joint is the part that connects the high-pressure oil pipe and the high-pressure oil pipe in the hydraulic system. Hydraulic pipe joints can be divided into hydraulic hoses, high-pressure ball valves, quick connectors, ferrule-type pipe joints, welded pipe joints, high-pressure hoses, transitional pipe joints, ferrule-type pipe joints, three-way pipe joints, non- Standard pipe joints, flared pipe joints, right-angle pipe joints, rotary pipe joints, quick joints, stainless steel pipe joints, copper joints, etc. For hydraulic pipe joints with thin outer walls, it will cause deformation if you do not pay attention to them during processing , the hydraulic pipe joints at this stage are prone to deformation and the processing accuracy is low.
