Abstract

The invention discloses a five-roll straightener which comprises an upper compression roll set, a lower compression roll set and a rack. The lower compression roll set is fixedly arranged on the rackand comprises three parallel lower compression rolls. The upper compression roll set and the lower compression roll set are arranged oppositely up and down, the centers of two upper compression rollsin the vertical direction are each aligned with a position between the corresponding two adjacent lower compression rolls. An upper fixing base is connected to a lifting device. The lifting device candrive the upper fixing base to move up and down, and accordingly the distance between the upper compression roll set and the lower compression roll set in the vertical direction is regulated. Compared with the prior art, the five-roll straightener provided by the invention can be used for improving the steel belt straightening efficiency, accordingly the uncoiling speed is increased, and accordingly the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of steel strip production equipment, in particular to a five-roller straightening machine. Background technique [0002] After the steel strip is uncoiled, it must first be processed by a straightening machine, and then sent to the feeding platform for subsequent processing. The function of the straightening machine is to straighten the originally bent steel strip head, so that the steel strip can be smoothly transported after entering the feeding platform. [0003] The straightening machine adopted in the current factory workshop is a double-roll straightening machine, which includes an upper pressing roller and a lower pressing roller. The upper pressing roller and the lower pressing roller are all made of rubber rollers. During the straightening process, it is necessary to stay for different times according to the bending degree of the steel strip head to ensure that the straightening is in place. Howev...
