Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages: although the two-curve structure of the straightening roller can be used to straighten steel pipes with different diameters, the straightening roller has an integrated structure, and the range of diameters of the steel pipes that can be straightened depends on the shape of the straightening roller. Size-related, its range is relatively fixed and cannot be adjusted

Abstract

The invention discloses a combined steel pipe straightening roller and a straightening device thereof, and relates to the technical field of steel pipe straightening. The invention aims to solve the problem of range adjustability. The combined type steel pipe straightening roller specifically comprises an adjustable frame structure fixed to the ground through supporting legs, the adjustable framestructure comprises a base and a top plate, first screws are connected to the inner walls of the opposite corners of the top plate through threads, and second screws are rotatably connected to the inner walls of the other opposite corners of the top plate; and the inner walls of the bottoms of the first screws make contact with the outer portion of the top of the base. According to the combined steel pipe straightening roller and the straightening device thereof, by hyperbolic surface structures of first roller blocks and second roller blocks, the range of the pipe diameter of a straightened steel pipe can be guaranteed; and adjusting cushion blocks are arranged between the first roller blocks and the second roller blocks, and the distances between the first roller blocks and the second roller blocks can be adjusted by adjusting the number of the adjusting cushion blocks between the first roller blocks and the second roller blocks, so that the pipe diameter range of the straightened steel pipe is changed, and the range of the straightened steel pipe is expanded.

Description

technical field [0001] The invention relates to the technical field of steel pipe straightening, in particular to a combined steel pipe straightening roller and a straightening device thereof. Background technique [0002] During the processing of steel pipes, the straightening mechanism is an important equipment in steel production. It is used to straighten uneven materials produced in heat treatment or other processes. Steel pipe bending is very important to product quality and directly affects the quality of the pipeline. Normal use. [0003] After searching, the Chinese patent application number is CN207103485U, which discloses a steel pipe straightening machine, including a straightening machine. The straightening machine is provided with a press for straightening steel pipes. The straightening at the bottom projection of the press is The surface of the machine is provided with a T-shaped slot with an upward opening, and an I-shaped steel is arranged inside the T-shape...
