Outlet guiding device of seamless steel pipe rolling mill

Abstract

The invention relates to an outlet guiding device of a seamless steel pipe rolling mill. The outlet guiding device of the seamless steel pipe rolling mill comprises at least three clamping points with adjustable positions. The following conditions which the clamping points is capable of satisfying are that when a steel pipe is divided by an axis going through a center of a circle at will through a steel pipe section, at least two clamping points are existed and located on a different side of the axis. A sealed guiding space can be formed by three crimpling points and control the steel pipe to beat. And the positions of the three clamping points can be flexibly adjusted according to needs to adapt guiding of the steel pipe with different calibers. Hydraulic drives with high accuracy are selected and used by driving devices, and the clamping points can be sent to the positions needed accurately. Each clamping point is driven by different driving devices. The adjustment is easy and convenient, flexible. To sum up, the outlet guiding device of the seamless steel pipe rolling mill has the advantages of being simple in structure, flexible to use and the like.

Description

technical field [0001] The invention relates to an outlet guide device for a seamless steel pipe rolling mill, in particular to an outlet guide for large-diameter steel pipes when they are rotated and rolled. Background technique [0002] At present, the known rolling mill exit guide is mainly composed of guide U-shaped guide grooves and upgraded supporting rollers. During the production process, the steel pipe protrudes from the exit of the main unit of the rolling mill while rotating, the lifting roller is at a low position, and the steel pipe moves along the U-shaped guide groove. The U-shaped guide groove controls the direction of the steel pipe to prevent the steel pipe from shaking too much and being damaged. After all the steel pipes are stretched out from the rolling mill, the lifting roller table lifts up to hold up the steel pipes and rotates to transport the steel pipes to the next process. However, the top of the U-shaped guide groove is open, and the sealing p...

AI Technical Summary

Problems solved by technology

However, the top of the U-shaped guide groove is open, and the sealing performance is not good, and the vertical jump of the steel pipe cannot be controlled. According to the different specifications of the steel pipe produced, different U-shaped guide grooves need to be replaced.
