Optimal shear setting method for slitting machine

Abstract

The invention relates to an optimal shearing setting method for a slitting machine unit. Information of supplied materials is collected, wherein the information comprises a width, a reel number, a starting point position Qi of severe defects and corresponding widths Li of all the defects. Finished product widths DLm needing shearing and corresponding roll numbers Pm of all the widths are set on an interface. A starting point position NQj and corresponding lengths NLj of starting point positions of all segments of segmented non-defective belt materials are obtained according to the width, the starting point position Qi and the widths Li. The number of small rolls of the segmented belt materials, starting points DQtau of all the rolls, lengths DLtau of all the rolls, the effectiveness of the rolls and whether the rolls are qualified or not are obtained through algorithms according to the starting point position NQJ of the segmented non-defect belt materials, the corresponding lengths NLj of the starting point positions of all the segments, the set finished product widths DLm needing shearing and the corresponding roll numbers Pm of all the widths. The maximum rate of finished products is calculated according to coordinates of the defects of the surfaces of the belt materials, the given shearing widths and the roll numbers, the problem of severe defects in the small rolls which are cut off is effectively solved, and the rate of finished products is obviously improved.

Description

technical field [0001] The invention relates to a method for setting optimal shearing of a slitting machine, and belongs to the technical field of nonferrous metal processing and forming technology. Background technique [0002] The slitting line is a production line that uncoils, slits, rewinds, and processes metal coils into coils of required width. It is mainly used in many industries such as automobiles, electrical engineering, electric power, and home appliances. etc.) are sent to the slitting machine after being uncoiled and pinched, and then longitudinally cut into narrow strips of different numbers and widths by the slitting machine, which are widely used in household appliances, pipe making, hardware, packaging and other industries. [0003] With the rapid development of related industries, the quality requirements for products processed by slitting line production equipment are also getting higher and higher. If serious defects are found inside the cut coil, the e...

AI Technical Summary

Problems solved by technology

If serious defects are found inside the cut coil, the entire coil will be judged inferior or scrapped, which will affect the strip yield
