Problems solved by technology

Therefore, it is necessary to carry out surface treatment on the surface of the pipe, and the surface treatment of the pipe needs to be fixed with a special fixture, so the contact surface between the fixture and the pipe becomes a blind spot, and there are still a few defects in the pipe after treatment, which affects the overall quality of the pipe
As a result, the local resistance to pitting corrosion of the pipe is greatly reduced, and the service life of the pipe is shortened

Embodiment Construction

[0013] A clamping mechanism, the clamping mechanism 30 includes an outer sleeve 31 for being inserted into the lumen of a pipe material A to be processed, and the outer sleeve 31 is provided with a first support portion 34 and a second support portion 35, the Any one or both of the first and second supporting parts 34 and 35 can be against the inner wall of the lumen of the tubing A to be treated.

[0014] The clamping mechanism 30 is fixed on the horizontal movement mechanism. The clamping mechanism 30 includes a fixed unit 36 ​​and a drive unit 60 for driving the fixed unit 36 ​​to move up and down. The fixed unit 36 ​​is provided with a plurality of outer sleeves 31, many The outer sleeves 31 are distributed in a matrix, and their positions and numbers correspond to the tubular area B of the transfer mechanism 20 .

[0015] The clamping mechanism 30 also includes an extrusion head 32 arranged in the inner cavity of the outer sleeve 31, the extrusion head 32 is fixedly conne...

Abstract

The invention relates to the field of pipe surface treatment, in particular to a clamping mechanism. The clamping mechanism comprises outer sleeves for being inserted in cavities of pipes A to be treated; each outer sleeve is provided with a first supporting part a second supporting part, and the first and second supporting parts can separately or simultaneously abut against the inner walls of thecavities of the pipes A to be treated. After the first and second supporting parts switch to clamp the pipes to be treated, the contact surfaces between the first supporting parts and the pipes A tobe treated are exposed, clamping mechanism bodies continue to walk by carrying the pipes A to be treated, clamping points between the first supporting parts and the pipes A to be treated are subjectedto surface treatment, and thus clamping blind points are avoided. Besides, the contact surfaces between the first and second supporting parts and the pipes A to be treated are located in the inner cavities of the pipes, the outer surfaces of the pipes to be treated are in an exposed state all the time, surface treatment can be sufficiently performed, and the quality of pipe surface treatment is improved.

Description

technical field [0001] The invention relates to the field of pipe surface treatment, in particular to a clamping mechanism. Background technique [0002] Pipes are widely used in production and life. With the continuous extension of uses, the performance requirements of pipes are also constantly improving. Especially in some special working occasions, the pipe must have super corrosion resistance, wear resistance, adhesion performance and so on. The quality of these properties of the pipe depends not only on the properties of the material itself, but also on the surface properties of the material. Therefore, it is necessary to carry out surface treatment on the surface of the pipe, and the surface treatment of the pipe needs to be fixed with a special fixture, so the contact surface between the fixture and the pipe becomes a blind spot, and there are still a few defects in the pipe after treatment, which affects the overall quality of the pipe. As a result, the local resis...
