Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] Taking radial linear friction welding of 45 steel radial ring and 45 steel steel pipe overlapping pipe as an example, the connection process and device use of radial linear friction welding in pipe welding are explained in detail.

[0041] Such as Figure 1-Figure 6As shown, a pipeline high-frequency vibration radial linear friction welding device includes a radial ring 5 that can be sleeved on the outer surface of a pipeline 6. A support bolt 4 is arranged inside the pipeline 6. The outer surface of the radial ring 5 is connected with several One end of the radial top block 2 evenly arranged in the circumferential direction of the radial ring 5 contacts, and several radial top blocks 2 are respectively inserted in a plurality of limiting grooves 9 on the limiting groove body 3, and the other end of the radial top block 2 is in contact with the ...

Abstract

The invention discloses a high-frequency vibration radial linear friction welding device for pipelines. The high-frequency vibration radial linear friction welding device comprises a radial ring. The radial ring can sleeve the outer surface of a pipeline, a support cotter is arranged in the pipeline, the outer surface of the radial ring is in contact with an end of each radial convex piece, the multiple radial convex pieces are peripherally and uniformly arranged and are respectively inserted in a plurality of limiting grooves in a limiting groove body, and the other end of each radial convex piece is in contact with the wedge-shaped inner wall of a radial reversing fixture; the reversing fixture is clamped on a vibrating body controlled by a controller, force is applied to the reversing fixture by the vibrating body, the convex pieces which are in contact with the reversing fixture drive the radial ring to vibrate at a high frequency in a reciprocating manner along the axial direction of the pipeline, axial thrust is simultaneously exerted on the reversing fixture and is converted into radial thrust, accordingly, the radial ring and the pipeline are pushed against each other and generate heat by friction, upset forging is stopped at a preset upset forging moment, and the pipeline is completely welded. The invention further discloses a welding process implemented by the aid of the high-frequency vibration radial linear friction welding device.

Description

technical field [0001] The invention relates to a welding process and device, in particular to a pipeline high-frequency vibration radial linear friction welding device and process. Background technique [0002] At present, pipeline transportation, as one of the five major transportation industries of railways, highways, sea transportation, civil aviation and long-distance pipelines, plays an important role in the construction of the national economy. Its transmission medium is mainly common oil and natural gas, and there are also industrial gases and chemical liquids. The construction of the pipeline network requires an effective pipeline welding process; in addition, the promotion of the concept of high efficiency and energy saving puts forward requirements for the efficient connection of pipelines. [0003] There are many ways to realize pipeline welding. The common welding methods are arc welding, laser welding, flash butt welding, high frequency rotary arc welding, axi...
