Metal corrugated pipe post-forming surface treatment method

Abstract

The invention provides a metal corrugated pipe post-forming surface treatment method. A metal corrugated pipe post-forming surface treatment device is used and comprises a base, a clamping mechanism and a polishing mechanism. Through the metal corrugated pipe post-forming surface treatment method provided by the invention, the following problems in the metal corrugated pipe post-forming surface treatment process can be solved that a, after metal corrugated pipes are formed, impurities such as burrs can be generated on the surfaces of the metal corrugated pipes, the metal corrugated pipes needsto be polished, due to the wavy outer walls of the metal corrugated pipes, the outer walls of the corrugated pipes are difficult to polish through equipment, so that most of the corrugated pipes aremanually polished through tools, thus the labor intensity is high, and the working efficiency is low; and b, an existing polishing device is expensive and single in function, and can only polish the surfaces of the metal corrugated pipes of the same specifications, so that the practical value of the existing polishing device is lower than the price.

Description

technical field [0001] The invention relates to the technical field of bellows processing, in particular to a method for surface treatment of metal bellows after forming. Background technique [0002] Metal bellows refers to a metal pipe made of galvanized or non-galvanized low-carbon steel strip spirally folded and used to reserve holes in post-tensioned prestressed concrete structural members. It is a regular wave-like appearance. Pipe materials, commonly used metal bellows are carbon steel, stainless steel, steel lined with plastic, aluminum and so on. It is mainly used for non-concentric axial transmission with small bending radius, or irregular turning, expansion and contraction, or absorbing thermal deformation of pipelines, etc., or it is not convenient to use fixed elbows to connect pipelines, or to connect pipelines with pipelines. device connection. [0003] At present, the following problems exist in the surface treatment process of the metal bellows after formi...

Device connection and use

[0003] At present, the following problems exist in the surface treatment process of the metal bellows after forming: a. After the metal bellows is formed, impurities such as burrs will appear on the surface, which need to be polished. Due to its wavy outer wall, the corrugated It is difficult to grind the outer wall of the pipe through equipment, so most of them are manually polished by tools, which makes the labor intensity high and the work efficiency low; b. The existing grinding device is expensive and has a single function, and can only be used for metal bellows of the same specification Polish the surface so that its practical value is lower than the price itself
