An Optimal Segmented Automatic Shearing Control System for Thick Plate Cutting Shear

Abstract

The invention discloses an optimal segmentation automatic shearing control system for a heavy plate crop shear. Edge contour coordinate data of a rolling large plate detected by a plane shape detection device can be taken as a base to obtain the center line and inclination angle of the large plate; the center line can be taken as a reference to arrange planning motherboards in the rolling large plate and calculate the actual segmentation length of the planning motherboards; corresponding processing method and segmentation shearing positions of a crop shear can be set according to the differentlength intervals of the rest steel plates; and corresponding segmentation shearing plans can be sent to basic automation equipment to execute shearing works. The segmentation positions of the motherboards can be optimized by arranging the motherboards through the center line, and therefore, that all finished plates in the motherboards of each segmentation can be completely cut out can be ensured,no superfluous wastes of the motherboards in the length direction can be guaranteed, and rolling yield can be enhanced; and the optimized segmentation shearing positions play an important role in improving site logistics.

Description

technical field [0001] The invention relates to thick plate automatic shearing equipment, more specifically to an optimal shearing control system of thick plate cutting head shears. Background technique [0002] In order to realize the automatic segmental shearing of thick plate shears and the segmental shearing position needs to be accurate, the difficulty lies in the non-rectangular planar shape of the rolled slab and the diversity of the two-dimensional arrangement of the finished slab on the rolled slab ( For example, the 5-meter-thick plate is divided into sequential type A group board: one finished board in the width direction, and the length direction is sequentially arranged; the split type S group board: two finished boards in the width direction, and the length direction is arranged side by side sequentially; fire-cut type Group G boards: One or more finished boards in the width direction are arranged side by side as a board, and the boards are arranged in the orde...

Problems solved by technology

However, in actual production, the actual plane shape of the rolled slab is affected by many factors, that is, the plane shape is largely unpredictable (such as rolling camber, etc.) Partially equal, it is impossible to keep the center line of the rolled slab parallel to the X axis

It can be seen that the disadvantages of the above-mentioned patented technology are: the influence of the skew of the center line of the rolling slab on the calculation of the final segment length is not considered, so that there is a large deviation in the calculation of the segment length of the mother plate, which ultimately affects the cutting head. The accuracy of cutting segments may even lead to the short length of some finished boards out of contract, which is not conducive to the improvement of the yield of thick plates
