AI Technical Summary

Problems solved by technology

In previous constructions, the on-site correction of metal pipes was generally made of thick steel pipes and manually adjusted by using the effect of extrusion and expansion. The size of the diameter of the metal pipe is likely to cause the surface of the metal pipe to break, and it is very easy to cause a safety hazard; in addition, there are also some steel pipe recovery devices, but they all have the problems of complex structure, high manufacturing and use costs, cumbersome and inconvenient operation, and cannot meet people's requirements.

Abstract

The invention relates to the field of metal fatigue recovery devices, in particular to a metal thin pipe fold recovery device. The device comprises a workbench; two positioning and guiding assemblies arranged at the two ends of the workbench correspondingly; a clamp assembly arranged in the middle of the workbench and located between the two positioning and guiding assemblies; a rotating mechanism located at one end of the workbench; and an expansion device, wherein the expansion mechanism comprises a tight supporting mechanism and a driving mechanism, the driving mechanism is arranged at the end, close to the rotating mechanism, of the workbench, the tight supporting mechanism is located on the inner side of the clamp assembly, the tight supporting mechanism is connected with the driving mechanism through a telescopic mechanism, and the driving mechanism is in transmission connection with the rotating mechanism. The metal thin pipe fold recovery device solves the technical problems that some existing metal thin pipe recovery devices are complex in structure, high in manufacturing and using cost and tedious and inconvenient to operate.

Description

Technical field[0001]The present invention relates to the field of metal fatigue recovery devices, and in particular, to a metal thin pipe crease recovery device.Background technique[0002]Nowadays, many areas are inseparable from the use of pipes, construction projects, power plants, chemical plants, etc., have such pipes, have standard GB / T5310; for high-pressure boilers: have standard GB / T8163; transport fluid seamless steel pipe : There is a standard GB3087; seamless steel pipe for low pressure boilers: Execution standard GB / T9948; petroleum cracking seamless steel pipe: Execute standard GB / T14976; fluid delivery stainless steel seamless steel pipe, common material has alloy (15CRMO, 12Cr1MOV) Carbon steel (10 #, 20 #, 45 #) stainless steel (304, 316). Metal tube is an important component of modern industrial equipment connecting line. Currently, it is already very mature in production technology and use. Due to its excellent performance and relatively economic cost, deve...
