Automatic roll changing system of row straightener

Abstract

The invention discloses an automatic roll changing system of a row straightener. The automatic roll changing system comprises a high-rigidity combined rack, an automatic locking type upper straightening roll assembly, an automatic locking type lower straightening roll assembly, a clutch type pressing device, an automatic roll changing device, a roll changing track, a base, a standby automatic rollchanging device and a measurement and control system. The standby automatic roll changing device before roll changing is used for preparing the row straightener, the automatic roll changing device isused for lifting a to-be-changed straightening roll set, an old straightening roll set is moved out, a roll changing separation platform is separated for the second time, a new straightening roll setand an old straightening roll set are rapidly replaced, the roll changing separation platform is positioned and locked, an operation side rack is reset and locked, the straightening roll set is locked, after roll changing is completed, roll changing auxiliary equipment is withdrawn, and the automatic roll changing of the straightener is completed through the eight steps of the automatic roll changing system.

Description

technical field [0001] The invention relates to a row straightening machine, in particular to an automatic roll changing system for a mobile straightening machine with a frame on the operating side. Background technique [0002] The straightening of small steel usually adopts cantilever type straightening machine; it is suitable for offline straightening process. The frame of the cantilever straightening machine is a welded overall frame. The straightening roller is installed on the cantilever shaft end of the straightening machine. The bearing on the operation side of the straightening machine bears a greater force than the bearing on the transmission side, and the cantilever shaft end has a large deflection. Due to the cantilever arrangement of the straightening rolls and the narrow width of the roll surface, it is difficult to arrange multiple passes, and it is impossible to straighten multiple steel profiles at the same time, and the capacity matching of the rolling line...

AI Technical Summary

Problems solved by technology

However, the hydraulic cylinder used for the vertical movement of the upper straightening roller has high requirements, the hydraulic system is complicated, and the maintenance requirements are high. Therefore, the overall technical and economic advantages are not obvious, and the defects have a great impact on the application of small steel row levelers.

Due to the compact structure of the small steel waste straightening machine and the small distance between the straightening rollers, it is impossible to arrange hydraulic cylinders on both sides of the straightening machine frame; It is not suitable for the equipment selection requirements of small steel row straightening machines
