Description

TECHNICAL FIELD

[0002] When the strip shape processing technology is carried out on copper and copper alloy strip, especially thin strip, the imported equipment B+S imported straightening unit or multi-roller mill is needed to produce through the shape meter. After the strip is stretched, the strip is straightened through the above-mentioned straightening roll system (the roll system diameter is 16mm, 20mm, 25mm) after being built through the multiple tension rolls. The strip shape control requirements of the edge and the middle part are strict during the straightening process. Because the strip shape of the edge and the middle part is inconsistent, the cross-section performance of the strip is not uniform. The existing straightening machine can adjust the strip shape through the deflection adjustment, but the deflection adjustment can only adjust the front and rear inclination angle manually, and the adjustment range is limited. When the incoming material shape is single-side wave, the improvement effect is not obvious, and the good product rate can only reach 60%, which causes a large amount of waste products. When the incoming material shape is middle wave, the included angle is small, the work roll rigidity is insufficient, the improvement effect is not obvious, and the good product rate can only reach 50%. The whole machine can only adopt the constant tension mode, and the elastic-plastic deformation amount generated during repeated straightening is small, so the wave shape, buckling and other defects of the strip cannot be completely eliminated.

The machine can run in constant tension mode or elongation rate mode, the elastic-plastic deformation generated during repeated straightening is large, and then the wave shape, curling and other defects of the strip are improved to achieve the purpose of correcting the strip shape.
