Problems solved by technology

[0003] Since the leveling and straightening of thin plates and extremely thin cold-rolled strips are generally completed by bending and leveling machines under the action of tension, the tension is provided by the tension rollers before and after the bending and leveling machine, while the existing bending Straightening machines such as one bending and one straightening, two bending and one straightening, etc., are mainly due to insufficient capacity, and the straightened plate shape cannot meet the high-quality requirements, such as the requirements for the production of automobile plates.

Abstract

A roller system for the band steel stretching straightener is composed of two groups of bending rollers and a group of straightening rollers. Each group comprises upper and lower roller groups consisting of working roller, intermediate roller and supporting roller. Said straightener features that all the roller groups are installed on its machnie frame and the spray tubes are installed at side of roller groups for wet stretching and wet straightening.

Description

technical field [0001] The invention relates to a cold rolling equipment, in particular to a strip steel stretching bending straightening machine roll set and a straightening machine thereof. technical background [0002] In the cold-rolled sheet factory, the shape of the cold-rolled sheet is one of the key indicators of the quality of the steel sheet. With the development of science and technology, the requirements for the flatness of thin strip steel and ultra-thin strip steel are getting higher and higher. Steel plate straightening machines have experienced multi-roll straightening machines, tension straightening machines, and bending straightening machines. Among them, the bending straightening machine is widely used in units that require continuous stretching and bending straightening machines to solve the following problems of steel plates: eliminate the yield platform of the strip steel; improve the tensile strength and plastic deformation range; improve the flatness ...
