Straightening and repairing device for metal pipe machining

Abstract

The invention discloses a straightening and repairing device for metal pipe machining, and relates to the technical field of pipe machining. The device comprises a frame plate, and a mounting frame isvertically fixed to the surface of one end of the frame plate; the mounting frame comprises two rectangular plates; the opposite surfaces of the two rectangular plates are rotationally connected withan annular plate; straightening frames are arranged on the inner wall of the annular plate in an annular array manner; a rectangular frame is arranged on the outer side of one rectangular plate; twopipe inlet guide rollers which are symmetrically arranged are arranged between the top and the bottom of the rectangular frame in a sliding fit mode; one end of the frame plate is rotationally connected with a pipe frame; repairing frames are arranged on the peripheral side surface of the pipe frame in a sleeving mode; and a central shaft frame matched with the repairing frames is rotationally connected between the two ends of an inserting pipe. The pipe is guided and conveyed through two pipe inlet guide rollers, when the annular plate rotates, multiple straightening rollers straighten the bent position of the pipe, under the action of the center shaft frame, the multiple repairing frames extend along the outer wall of the pipe frame to bulge the concave position of the inner wall of thepipe, the straightened pipe is repaired, and the actual use requirement is met.

Description

technical field [0001] The invention belongs to the technical field of pipe processing, in particular to a straightening and repairing device for processing metal pipes. Background technique [0002] Metal pipes, also known as steel pipes, are used to transport fluids and powdery solids, exchange heat, manufacture mechanical parts and containers, and are also an economical steel. The development of the chemical industry, as well as the drilling and transportation of oil and gas, have all vigorously promoted the development of the steel pipe industry in terms of variety, output and quality. Steel pipes can be divided into two categories according to production methods: seamless steel pipes and seamed steel pipes, which can be used in various industries for liquid pressure pipes, gas pipes, water pipes, gas pipes, heating pipes, electrical pipes, etc. [0003] The straightening machine uses straightening rollers to squeeze pipes, etc. to change the straightness. Generally, t...
