Problems solved by technology

Because during the rolling process, the steel pipe is rotating at high speed, while the guide cylinder is fixed, which will cause friction damage between the surface of the steel pipe and the guide cylinder, especially when rolling a steel pipe with a thickness below 8mm, it is easy to The overall distortion of the steel pipe appears, and if the distortion is serious, it may directly become a twisted shape, or even get stuck in the guide tube and cannot come out, which will easily cause great damage to the equi

Abstract

The invention belongs to the technical field of steel tube rolling tools and particularly relates to an after-roll guide cylinder rotating device. The after-roll guide cylinder rotating device comprises a pedestal, wherein a guide cylinder support frame is arranged on the pedestal, a guide cylinder is arranged on the guide cylinder support frame, guide cylinder bearings are arranged on outer side walls of two ends of the guide cylinder, and the guide cylinder can rotate on the guide cylinder support frame through the guide cylinder bearings; a transmission gear is connected to one end of the guide cylinder, and a fixed gear is arranged on the pedestal, is connected with a motor and is meshed with the transmission gear. According to the after-roll guide cylinder rotating device, the distortion of a thin-wall steel tube can be prevented in a rolling process of the steel tube, the surface quality of the steel tube is guaranteed, and the device is convenient to dismount and exchange.

Description

technical field [0001] The invention belongs to the technical field of steel pipe rolling tools, in particular to a post-rolling rotating guide cylinder device. Background technique [0002] At present, most of the guide cylinders in the background of the pipe rolling mill are welded and fixed by steel pipes. Although the production is relatively simple, it has serious disadvantages, and cannot make high-demand, high-precision steel pipes. Because during the rolling process, the steel pipe is rotating at high speed, and the guide cylinder is fixed, which will cause friction damage between the surface of the steel pipe and the guide cylinder, especially when rolling a steel pipe with a thickness below 8mm, it is easy to The overall distortion of the steel pipe occurs, and if the distortion is severe, it may directly become a twisted shape, or even get stuck in the guide tube and cannot come out, which will easily cause great damage to the equipment and cause production to fai...
