Problems solved by technology

[0002] At present, in the steel pipe industry, it is necessary to straighten the produced steel pipes. If only manual beating is used for straightening, the correction effect is very poor and the efficiency is low. Other steel pipe straightening devices in the prior art generally can only achieve rough Straightening, at the same time, defects such as distortion and deformation of the pipe wall will occur during the straightening process of the steel pipe

Abstract

The invention discloses a steel pipe straightening device. The steel pipe straightening device comprises a load bearing platform and a rotary frame; supporting columns are installed at the upper end of the load bearing platform; a steel frame is fixedly connected to the upper ends of the supporting columns; first telescopic rods are installed at the lower end of the steel frame; a row of upper pressing rollers are connected to the lower ends of the first telescopic rods; second telescopic rods are installed at the upper end of the load bearing platform; a row of lower pressing rollers are connected to the upper ends of the second telescopic rods; telescopic rod bodies distributed uniformly are fixedly installed in an inner cavity of the rotary frame, and pressing roller bodies are arranged at the lower ends of the telescopic rod bodies; the two sides of the rotary frame are provided with through holes; a transverse rod is connected into the through holes in a sleeved mode; supporting rods are fixedly connected to the two ends of the transverse rod; a belt wheel is rotationally connected to the middle of the rotary frame through a belt; and a motor is rotationally connected to the belt wheel. The steel pipe straightening device is reasonable in structure, convenient, practical and better in straightening effect.

Description

technical field [0001] The invention relates to the technical field of pipeline production, in particular to a steel pipe straightening device. Background technique [0002] At present, in the steel pipe industry, it is necessary to straighten the produced steel pipes. If only manual beating is used for straightening, the correction effect is very poor and the efficiency is low. Other steel pipe straightening devices in the prior art generally can only achieve rough Straightening, at the same time, defects such as distortion and deformation of the pipe wall will occur during the straightening process of the steel pipe. Therefore, a steel pipe straightening device that does not cause damage to the pipe wall is needed. Contents of the invention [0003] The object of the present invention is to provide a steel pipe straightening device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present inven...
