Vertical rods 16 are symmetrically installed at the upper end of the pressure plate 11. A sliding hole 17 is opened inside the vertical rod 16. A guide rod 18 is installed on the upper part of the lifting plate 21. A guide block 19 is slidably connected to the outer surface of the guide rod 18, and the guide block 19 is fixedly connected to the lifting plate 21. A spring 20 is sleeved on the outer surface of the guide rod 18, and the spring 20 is located at the lower end of the guide block 19. A movable block 22 is installed on the upper end of the lifting plate 21. A movable hole 23 is opened inside the movable block 22. A groove 24 is opened at the top of the movable hole 23.

The bolt 26 and the movable block are connected to each other. The 22 is threaded. Several moving blocks 22 are provided with positioning rods 27 inside, and the positioning rods 27 pass through the moving holes 23. The rear end of the positioning rods 27 is provided with scale lines 28.

The upper end of the several hydraulic cylinders 31 is equipped with an L-shaped plate 32, and the L-shaped plate 32 is fixed to the upper end of the base plate 1.

[0021] The working principle of this utility model is as follows: the positions of the fixed blade 10 and the moving blade 211 are adjusted according to the cutting requirements, the support rod 8 is pushed to move and drive the slider 7 to move. At the same time, the support rod 8 drives the pressure plate 11 to move through the square rod 12 and the fixed block 13. The pressure plate 11 drives the lifting plate 21 and the moving blade 211 to move through the upright rod 16. Meanwhile, the moving block 22 moves outside the positioning rod 27. The position of the moving block 22 on the scale line 28 is observed to control the position of the fixed blade 10 and the moving blade 211, thereby adjusting the single cutting length of the silicon steel sheet. Then, the bolt 26 is rotated to drive the extrusion block 25 to descend and press against the rubber anti-slip strip 29, thereby fixing the position of the fixed blade 10 and the moving blade 211.

[0022] Then, one end of the silicon steel sheet is pulled through several fixed blades 10 and movable blades 211 and placed inside the U-shaped plate 2. One end of the silicon steel sheet abuts against the inner wall of the U-shaped plate 2. Then, the hydraulic cylinder 4 drives the pressing plate 3 to descend and press it against the upper end of the silicon steel sheet, thereby fixing the position of one end of the silicon steel sheet, so that the silicon steel sheet is placed on the upper end of several support rods 8. Then, the hydraulic cylinder 31 drives the positioning rod 27 to descend through the mating plate 30. The positioning rod 27 descends through the movable block 22, the lifting plate 21, the upright rod 16 and the pressure plate 11. At the same time, the fixed block 13 is in the square The rod 12 descends outward, causing the pressure plate 11 to press against the upper end of the silicon steel sheet. Then, the positioning rod 27 continues to push the moving block 22 down. Since the pressure plate 11 cannot descend because it is pressing against the silicon steel sheet, the moving block 22 pushes the lifting plate 21 down. The lifting plate 21 drives the guide block 19 down to compress the spring 20. At the same time, the lifting plate 21 drives the moving blade 211 down to pass through the blade hole 15. The silicon steel sheet is cut by the cooperation of the fixed blade 10 and the moving blade 211, so that the long silicon steel sheet can be cut into multiple short silicon steel sheets of different lengths at one time.
