Description
Technical Field
The application relates to the technical field of steel belt bending and straightening machines, in particular to straightening equipment and method for a stainless steel belt.
Background
In the current steel strip plate processing industry, a common plate straightening device provides plate tensile stress for front and back S rollers and straightens the plates through small-diameter straightening rollers. The principle of providing tensile stress by the S roller is as follows: the steel strip plate is driven to run by the static friction force between the steel strip plate and the front and back S rollers, and the tensile stress is provided by the speed difference between the front and back S rollers. The S roller provides a tensile stress with the following 3 point drawbacks: 1. the leading belts are required to be arranged at the head end and the tail end of the plate, and under the condition that the leading belts are not used, the steel belts with certain part of the length at the head end and the tail end cannot have the tension-straightening effect. 2. The tensile stress provided by the speed difference is not stable, and the tensile stress is only calculated, so that the magnitude of the tensile stress cannot be controlled very accurately. 3.S roller provides straightening tensile stress one end rolling, one end unreeling, must one shot forming, and the problem that appears in the withdrawal and straightening process can't be solved immediately, can only carry out the secondary again and draw the straightening of whole steel band after whole steel band draws and straightens to cause the waste of productivity.
The straightening principle of the small-diameter straightening roller is as follows: the small-diameter straightening roller acts on the steel strip to bend the steel strip, the bending part is subjected to quite large reverse bending or stretching, certain elastoplastic deformation is generated at the bending part, and when the external force is removed, the steel is elastically restored and then is straightened. The straightening of the small-diameter straightening roller has 2 defects: 1. when the small roller is used for straightening, as the diameter of the straightening roller is small, the straightening control precision requirement is extremely high, once the steel belt forms a wrap angle on the small straightening roller, the bending stress exceeds the stretching limit of the steel belt, so that the steel belt is damaged, and the steel belt is scrapped; 2. the shape condition can not be detected in the straightening process of the small straightening roller, and the shape effect is not ideal after straightening, so that the whole steel belt needs to be straightened again.
Therefore, development of equipment and process for straightening stainless steel strips is very necessary to improve the quality of steel strip formats and reduce the waste of raw materials and productivity.
