Embodiment Construction

[0041] The optimal shearing setting method of the slitting unit of the present invention, the specific steps are:

[0042] 1) Collect incoming material information, including: width, roll number, starting position Q of serious defects i And the width L corresponding to each defect i , the information of the incoming material is expressed in the form of an excel form, read from the form; set the width DL of the finished product that needs to be cut out on the interface m And the number of rolls P corresponding to each width m ;

[0043] 2) It is necessary to adjust the starting position Q i and width L i , to process the data of serious defects in the material, remove the overlapped part in the width direction, and obtain a new starting position Q without overlap i2 And the width L of the corresponding defect i2 ;

[0044] According to the strip width L and defect data Q i2 and L i2 , to obtain the starting position NQ of the segmented defect-free strip j And the leng...

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...
