[0002] The cold-rolled sheet is characterized by high requirements for dimensional accuracy and surface quality. Width accuracy is the main control point for dimensional accuracy. The cold-rolled sheet after annealing is commonly known as soft cold-rolled sheet. In actual production, due to the Due to factors such as uneven material hardness, plate shape control deviation during the cold rolling process, and soft shear equipment installation accuracy deviation, the cold rolled sheet often deviates before entering the soft slitting shear axis, which leads to edge jamming and edge waves. , inaccurate dimensions and other defects, so that the high performance requirements of the soft cold-rolled sheet cannot be guaranteed, resulting in a great loss of yield

[0003] In the prior art, some technical solutions of cold-rolled sheet slitting equipment have also appeared. For example, a Chinese patent with application number 201220683209.9 discloses a cold-rolled sheet slitting equipment. The technical solution is: its support There are two, the two ends of the guide light rod are fixed on the support, and one end of the two transmission screw screws is respectively installed on the support at both ends, the hand wheel is respectively connected with the two ends of the two transmission screw The other end of the lead screw is coaxially rotatably connected with the two ends of the lead screw connecting cylinder. The upper ends of the two vertical roller brackets are respectively set on the two ends of the guide light rod. The two vertical roller brackets have screw holes for the screw respectively. The two transmission screws are passed through the screw holes of the two vertical roller brackets respectively, and the guide vertical rollers are vertically installed in the two vertical roller brackets. This technical scheme adjusts the center of the cold-rolled sheet through the guide vertical rollers on both sides. Avoiding the phenomenon of edge jamming and edge waves, but because the thickness of the cold-rolled sheet is relatively thin, especially the soft-state cold-rolled sheet after annealing, it is easy to bulge and deform the middle part of the cold-rolled sheet when adjusting the guide and vertical rollers.
