The output end of the hydraulic cylinder 81 is installed with a lower die 82. The top side of the lower die 82 is installed with an upper die 83 fixed on the surface of the cross beam 11. During shearing, the hydraulic cylinder 81 pushes the fixedly installed lower die 82 to move, and the upper die 83 cooperates with the lower die 82 to realize the shearing of the steel coil.

[0031] Furthermore, the leveling mechanism 6 includes a fixed side plate 61, leveling rollers 62, a lifting assembly 63, and a movable side plate 64. The fixed side plate 61 is fixedly installed on the surface of the frame 1. The top side of the fixed side plate 61 is installed with a movable side plate 64 slidably arranged inside the frame 1. Both the movable side plate 64 and the fixed side plate 61 are installed with leveling rollers 62.

The bottom end of the lead screw 635 is rotatably connected with the top side of the movable side plate 64.

[0034] In some embodiments, an upper roller 5 with height adjustment is arranged on the right side of the leveling mechanism 6. A roller frame is installed on the surface of the upper roller 5, and a stud threadedly connected to the surface of the cross beam 11 is installed on the top side of the roller frame. The provided stud can realize the gap adjustment between the upper roller 5 and the lower roller 4. A lower roller 4 installed on the surface of the frame 1 is arranged on the bottom side of the upper roller 5. A driving motor is installed on the roller frame on the surface of the upper roller 5, and the driving motor is connected to the lower roller 4. By driving the upper roller 5, the rotation of the lower roller 4 is driven. On the corresponding ends of the provided lower roller 4, the leveling roller 62 installed on the fixed side plate 61, and the lower strip dividing roller 72, there are cross-over gears, and the adjacent cross-over gears are meshed and connected. During the operation of the driving motor, the driving motor realizes the synchronous driving of the lower roller 4, the leveling roller 62 installed on the fixed side plate 61, and the lower strip dividing roller 72, so as to realize the automatic movement of the steel coil.

After the distance between the upper strip dividing roller 71 and the lower strip dividing roller 72 is adjusted, transverse cutting is realized through rolling operation.

[0036] When the small strip dividing cutting machine disclosed in this application is in use, through the cooperation of the pinch rollers 2 and the guide wheels 3, the stable guiding of the steel coil is realized. A lower roller 4 installed on the surface of the frame 1 is arranged on the bottom side of the upper roller 5. A driving motor is installed on the roller frame on the surface of the upper roller 5, and the driving motor is connected to the upper roller 5. By driving the upper roller 5, the automatic feeding of the steel coil passing through is realized. By manually operating the lifting assembly 63, the lifting assembly 63 adjusts the movable side plate 64, and the movable side plate 64 drives the leveling roller 62 installed on its surface to move, so as to facilitate the adjustment of the specific gap between the leveling roller 62 on the movable side plate 64 and the leveling roller 62 on the fixed side plate 61, so as to adapt to the leveling of steel coils with different thicknesses. After leveling, strip dividing dies are installed inside the surfaces of the upper strip dividing roller 71 and the lower strip dividing roller 72. After the distance between the upper strip dividing roller 71 and the lower strip dividing roller 72 is adjusted, transverse cutting of the steel coil is realized through rolling operation. During longitudinal shearing, the hydraulic cylinder 81 pushes the fixedly installed lower die 82 to move, and the upper die 83 cooperates with the lower die 82 to realize the shearing of the steel coil.
