Description

Corner passing transition joint machining process

Technical Field

The invention relates to a processing technology of a pipe joint, in particular to a processing technology of an angle passing transition joint.

Background

A pipe joint is a part for connecting a pipe line or mounting a pipe line to a hydraulic component in a hydraulic system, and is a generic name of a connecting member that can be attached and detached in a fluid passage. The angle passing transition joint is one of pipe joints, the traditional angle passing transition joint has multiple processing procedures, unstable quality and material waste, and steps and burrs are arranged at the joints punched at two ends, so that the burrs are difficult to remove and block an oil way when in use, thereby causing equipment shutdown or failure; when oil flows through the steps, abnormal noise is generated, and noise is generated.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

Referring to fig. 1, the present invention provides a corner passing transition joint processing method, which includes the following steps:

a. preparing materials, namely selecting a hexagonal pipe, wherein the middle of the hexagonal pipe is provided with a through hole, so that the step of punching can be effectively avoided, and the phenomena of burrs and steps can be avoided during punching;

b. material breaking: cutting the hexagon pipe in the step a into a broken material by a sawing machine, and calculating the length of the broken material according to the actual size of the transition joint passing through the angle;

c. bending: b, bending the broken materials by a bending machine, wherein the bending angle is determined according to specific requirements, and because the length of the broken materials when the angle passes through the transition joint is not very long, a manual bending machine or an automatic bending machine can be selected;

d. vehicle repairing: and c, turning and trimming the peripheral contour of the bent material in the step c to meet the size requirement through a numerical control lathe.

In the present embodiment, the angle of bending in step c is 90 °.

Referring to fig. 2, a conventional process for machining a corner-passing transition piece: which comprises the following steps:

a. cutting the straight bar into sections;

b. bending: b, heating the broken material in the step a to a temperature of about 900 ℃ in a high frequency mode, and bending;

c. stamping: pressing the bending material in the step b out of the mold through a punching machine;

d. trimming: c, trimming the stamping material in the step c;

e. vehicle repairing: c, trimming and picking the trimming skip in the step d to meet the size requirement;

f. punching: and (e) punching the two ends of the vehicle repairing material in the step (e).

Compared with the prior art, the processing technology of the angle joint transition joint is simplified in the process, so that the processing time and cost are reduced; secondly need not to punch through selecting hexagonal tubular product, further having practiced thrift raw and other materials and reached reduce cost's effect, still avoided the step of punching to step and burr because the step of punching produces have been avoided effectively, have improved the quality that the angle passes through the ferry-adaptor.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
