Strip steel stretching and straightening machine

Abstract

The invention provides a strip steel stretching and straightening machine. By the strip steel stretching and straightening machine, the problem of proneness to deflection of strip steel in operation is greatly improved, and damages of the strip steel in a straightening process can be effectively avoided. The strip steel stretching and straightening machine comprises a base, a stretching and straightening machine is mounted on the base through a supporting seat, two tension S rollers are mounted on two sides of the stretching and straightening machine, the stretching and straightening machine comprises a bending section and a straightening section, the bending section comprises at least two bending machines, the straightening section comprises at least two straightening machines, a first driving device is mounted at the bottom end of each of the bending machines and the straightening machines, and a second driving device is mounted at the top end of each straightening machine. Each bending machine comprises an upper roller and a lower roller in vertical corresponding arrangement, each straightening mechanism comprises two upper rollers in bilateral parallel arrangement, and a lowerroller is correspondingly arranged below the position between the two upper rollers. Guide rollers are symmetrically mounted on two sides of the supporting seat of the stretching and straightening machine and arranged corresponding to gaps between the upper rollers and the lower rollers of the stretching and straightening machine.

Description

technical field [0001] The invention relates to the technical field of strip steel leveling devices, in particular to a strip steel tension leveler. Background technique [0002] After the steel strip is annealed, pickled and other technological processes, the shape of the processed strip often does not meet the standards and cannot meet the requirements of the subsequent processing procedures. In the prior art, the strip is often straightened by a tension leveler. According to the mechanical principle of strip steel tension and straightening deformation, under the action of the large tension of the front and rear tension rollers, longitudinal tensile stress and bending stress are generated inside the strip steel. This kind of stress is changed by stretching and bending stress, and after several times of elastic bending under stretching state, the strip steel produces uniform plastic extension, the internal stress value is the same and the direction is consistent, so as to a...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems existing in the prior art that the strip steel is prone to deviation during operation and the strip steel is easily damaged, the present invention provides a strip steel tension leveler, which greatly improves the problem that the strip steel is prone to deviation during operation. problem, which can effectively prevent the strip from being damaged during the straightening process
