Description

Technical Field

[0001] The present invention relates to the technical field of steel coil slitting, and in particular to a cold-rolled steel coil slitting device. Background Art

[0002] Before use, cold-rolled steel coils must be slit into strips of desired width. However, existing slitting devices are prone to unevenness and warping during unwinding, which can cause deviations during slitting, affecting slitting accuracy and quality. Furthermore, the blades in some existing slitting devices are fixed and cannot be adjusted, making it difficult to adjust the slitting width. Summary of the Invention

[0005] Preferably, a cylinder rack is provided on the workbench, and guide grooves are vertically provided on the two opposite side walls of the cylinder rack. The two ends of the lifting roller in the length direction are movably arranged in the two guide grooves, so that the cylinder rack can drive the lifting roller to achieve lifting and lowering, thereby realizing the vertical position adjustment of the cold-rolled steel plate coil mounted on the outside of the lifting roller, which is conducive to smooth unwinding of the cold-rolled steel plate coil.

[0006] Preferably, a stabilizing roller assembly is provided on the side wall of the workbench, and the stabilizing roller assembly comprises: The upper stabilizing roller is rotatably arranged on the side wall of the workbench, and the axis of the upper stabilizing roller is parallel to the axis of the lifting roller; The lower stabilizing roller is arranged parallel to and spaced apart below the upper stabilizing roller. When the cold-rolled steel coil is unwinding, it passes between the upper and lower stabilizing rollers, which is beneficial to keep the cold-rolled steel coil smooth and stable when unwinding.

[0007] Preferably, the winding frame assembly includes: A roll-dividing rack, which is arranged on the top surface of the workbench; A rotating motor is arranged on the inner wall of the roll-dividing frame; There are multiple winding rollers, and the multiple winding rollers are arranged in sequence along the length direction of the output shaft of the rotating motor.

The length direction of the card slot, the length direction of the axis of the winding roller and the length direction of the pressure rod are all the same, which can clamp the strip head of the slit cold-rolled steel plate and prevent the slit cold-rolled steel coil from slipping when winding.

[0009] Preferably, the gap between the outer peripheral wall of the upper stabilizing roller and the outer peripheral wall of the lower stabilizing roller is in the same plane as the top surface of the slitting table, which is conducive to keeping the cold-rolled steel plate coil smooth and stable during unwinding and facilitating the slitting of the cold-rolled steel plate coil.

[0010] Preferably, the number of the winding rollers is greater than the number of the cutter discs, so as to facilitate the winding of the slit cold-rolled steel plate coils.

[0011] Preferably, the slitting table is provided with a plurality of fixing bolts, and a plurality of bolt holes compatible with the fixing bolts are provided on the top surface of the workbench. The fixing bolts pass through the slitting table and are threadedly connected to the bolt holes at corresponding positions, so that a corresponding number of slitting tables can be installed on the top surface of the workbench for use according to slitting needs, so as to complete the corresponding slitting quantity of the cold-rolled steel plate coil.

[0013] Preferably, the elastic block comprises: Block grooves are provided on the top surface of the left guide rod near the cutter disc and the top surface of the right guide rod near the cutter disc; A compression spring is vertically arranged on the bottom surface of the block groove; The block is arranged at one end of the compression spring away from the bottom surface of the block groove. The longitudinal section of the block is a right triangle, and the hypotenuse of the block faces the cutter disc, so that when the cold-rolled steel plate is unwound, the strip head of the cold-rolled steel plate can be limited by the elastic block; at the same time, when the push cylinder pushes the cutter disc frame toward the strip head of the cold-rolled steel plate, it can conflict with the hypotenuse of the block, so that the block can be squeezed and contracted into the block groove, so that the cold-rolled steel plate can be cut by the cutter disc.

[0014] The beneficial effects of the present invention are: 1. Multiple slitting stations and winding rack assemblies are set, and the number of winding rollers is greater than the number of knife discs, which makes it convenient to install a corresponding number of slitting stations for use according to slitting needs. The winding rollers in the winding rack assembly can rewind the slit cold-rolled steel plate coils, thereby realizing slitting of cold-rolled steel plate coils of different widths as needed.

[0015] 2. When the cold-rolled steel coil is unwinding, the lifting cylinder drives the lifting roller to move up and down, and at the same time, the cold-rolled steel coil passes between the upper stabilizing roller and the lower stabilizing roller during unwinding, thereby ensuring smooth unwinding of the cold-rolled steel coil, avoiding unevenness and warping, and improving the quality after slitting.

[0027] Example 1 like Figures 1 to 3 、 Figure 5As shown, the present invention provides a cold-rolled steel coil slitting device, including a workbench 1; a reeling frame 2 and a reeling frame assembly 3 are arranged at intervals at both ends of the top surface of the workbench 1; a slitting knife assembly 4 is located between the reeling frame 2 and the reeling frame assembly 3; the reeling frame 2 includes a lifting cylinder 21 movably arranged on the workbench 1, and a lifting roller 22 is rotatably arranged on the piston rod of the lifting cylinder 21; the slitting knife assembly 4 includes a plurality of slitting tables 41 arranged in sequence and side by side on the top surface of the workbench 1, and a slitting groove 42 is arranged on the top surface of the slitting table 41, and a slitting frame 43 is provided at the end of the workbench 1 away from the reeling frame 2, and a pushing cylinder 44 is provided on the slitting frame 43, and a plurality of cutter disc frames 45 are provided on the piston rod of the pushing cylinder 44, and a cutter motor 46 is embedded in the cutter disc frame 45, and a cutter disc 47 is provided on the output shaft of the cutter motor 46, and the position of the cutter disc 47 corresponds to the position of the cutter groove 42.
