Problems solved by technology

At present, clamp-type tensile straightening machines are often used for straightening single steel plates, but the equipment occupies a large area, consumes a lot of energy, and has low productivity. Force, the part clamped by the clamp often needs to be cut off, which will cause waste of plates

Abstract

The invention discloses a plate tension straightening device. A rear rack is fixedly connected with the rear end of guide columns, a front rack slides on the guide columns, upper pressing blocks and upper wedge blocks which are used for clamping a plate are mounted on each of the front rack and the rear rack, motors drive lower wedge blocks to horizontally move through lead screws, the lower wedge blocks push the upper wedge blocks to move up and down, pressing-down oil cylinders and pressing-down oil cylinder rods drive the upper pressing blocks to move up and down through upper supporting rods and lower supporting rods, and stretching oil cylinders and stretching oil cylinder rods drive the front rack to move back and forth through front horizontal supporting rods and rear horizontal supporting rods. The plate tension straightening device is simple in structure and can remarkably amplify driving force.

Description

technical field [0001] The invention relates to a plate processing equipment, in particular to a plate tension straightening device. Background technique [0002] For steel plates with three-dimensional shape defects, especially high-strength steel plates, it is often difficult to obtain the ideal shape after straightening through the existing roller straightening process. The reason is that the straightening of the three-dimensional defects of the steel plate by the roller leveler is obtained through indirect effects: the transverse deformation of the material caused by the longitudinal bending-reverse bending deformation and the uneven distribution of the longitudinal extension along the width of the plate. This indirect action mechanism is one of the most important factors restricting the ability of roller straightening to correct three-dimensional defects of steel plates. The tension straightening can directly act on the longitudinal defects of the steel plate, complete...
