Steel pipe diameter roundness correction device and roundness correction method

Abstract

The invention discloses a steel pipe diameter roundness correction device and a roundness correction method. The steel pipe diameter roundness correction method is conducted through the steel pipe diameter roundness correction device. The steel pipe diameter roundness correction device comprises a device body, wherein the device body is provided with a receding opening matched with the theoreticalouter diameter of a steel pipe; a plurality of inwards-concave structures are arranged on the inner side of the receding opening; adjusting pieces capable of being adjusted in the axial direction ofthe receding opening is arranged in the inwards-concave structures; and inclined structures are arranged between the adjusting pieces and the inwards-concave structures. According to the steel pipe diameter roundness correction device and the roundness correction method provided by the invention, the device body can be arranged at any position of a pipe opening of a steel pipe component and a steel pipe in a sleeving mode through the receding opening, then the adjusting pieces are moved in the axial direction of the receding opening, the pipe wall of the steel pipe can be extruded through theadjusting pieces, and when the error of the pipe diameter of the steel pipe is detected to exceed the range, the pipe diameter of the steel pipe can be adjusted through the adjusting pieces, so that the installation requirement is met.

Description

technical field [0001] The invention relates to a steel pipe processing technology, in particular to a steel pipe diameter correction device and a circle correction method. Background technique [0002] With the promotion of the application of prefabricated steel structures in the country, more and more large-scale steel pipe structures are used in steel structure bridges (such as bridge arch ribs) and steel structure construction projects. According to the design and the relevant national regulations, the diameter of the nozzle of the steel pipe component and any position of the steel pipe after processing must meet the relevant dimensional error requirements of the code. However, during the manufacturing process of the steel pipe structure, due to reasons such as steel pipe blanking, pipe rolling processing technology, and overall bending and simmering of the steel pipe length direction, the diameter of the steel pipe component nozzle and any position of the steel pipe can...

AI Technical Summary

Problems solved by technology

However, during the manufacturing process of the steel pipe structure, due to reasons such as steel pipe blanking, pipe rolling processing technology, and overall bending and simmering of the steel pipe length direction, the diameter of the steel pipe component nozzle and any position of the steel pipe cannot meet the design and specification requirements, resulting in The nozzles of two adjacent steel pipe components cannot be connected normally, and the diameter of any position in the steel pipe cannot meet the installation requirements of the stiffening ring in the pipe, often resulting in unqualified project quality
