AI Technical Summary

Technical Problem

The centering device of the existing billet rolling mill is prone to causing surface damage to the rolled workpiece when clamping it, which affects the quality of the rolled workpiece.

Method used

An alignment device was designed, comprising a support frame, a conveyor roller mechanism, and a transverse pusher mechanism. The device uses a swing linkage and a hydraulic cylinder to drive the pusher to approach or separate, thereby achieving alignment adjustment of the rolled piece and reducing hard contact damage through buffer contact.

Benefits of technology

It effectively avoids damage to the surface of the rolled piece, improves the processing quality and conveying efficiency of the rolled piece, reduces frictional resistance, and ensures the stability and reliability of the device.

Abstract

The utility model provides a centering device of a cogging mill, and belongs to the technical field of steel rolling equipment structures. The centering device comprises a supporting frame, a conveying roller way mechanism arranged on the supporting frame and a transverse moving push plate mechanism movably arranged on the supporting frame. The transverse moving push plate mechanism comprises a pair of push plates distributed on the two opposite sides of the conveying roller way mechanism at intervals, a plurality of swing connecting rods with one ends hinged to the supporting frame and a driving piece arranged on the supporting frame and used for driving the push plates to be close to or separated from each other. One ends of the multiple swing connecting rods are hinged to the supporting frame, so that the pair of push plates can be driven by the driving piece to be close to or separated from each other under swing of the swing connecting rods, on one hand, centering adjustment of a rolled piece is achieved, on the other hand, clamping or loosening of the rolled piece is achieved, and hard contact with the rolled piece is effectively avoided under swing of the swing connecting rods; and damage to the surface of a rolled piece is reduced.
