Abstract
The invention discloses a control method of oppositely cutting material board shape quality. The control method of the oppositely cutting material board shape quality comprises rip cutting and oppositely cutting, stretching-bending correction, and packaging. According to the control method of the oppositely cutting material board shape quality, more specific requirements are raised to rip cutting and stretching-bending correction, and an oppositely cutting finished product is finally produced in a stretching-bending correction line. Although the thickness of stretching-bending correction is not changed, the width of stretching-bending correction is 50 millimeters narrower than half of an original strip. When a narrow material finished product is produced, the capacity of a stretching-bending correction device can fully satisfy. Finally, strip board shape is obviously improved, wave height is controlled within 1 millimeter, and user requirements are fully satisfied. When an oppositely cutting semi-finished product is produced, the influences, caused by limitation of the capacity of the stretching-bending correction device, from the material width and the material thickness are eliminated. Finally, cutting material board shape quality is improved.
