[0029] Before cutting the silicon steel sheet, the silicon steel sheet cutting machine 100 can be started by adjusting the motor 131, and the movable column 210 can be adjusted by the driving mechanism so that the distance between the movable column 210 and the fixed column 220 is adjusted to a suitable position, and then the screw sleeve 312 can be inserted into the sliding frame 311, and the position of the screw sleeve 312 relative to the screw sleeve 312 can be fixed by using the positioning nut 314 and the sliding screw 313, and then the knife shaft 230 and the adjusting screw 320 corresponding to the silicon steel sheet model can be adjusted. Install it between the movable column 210 and the fixed column 220, and move the movable knife seat 340 on the knife shaft 230 until the movable knife seat 340 is adjusted to the cutting position corresponding to the silicon steel sheet, that is, the movable knife seat 340 is distributed from the fixed knife seat 231 to both ends along the surface of the knife shaft 230, and then by rotating the adjusting screw 320, the clamping turntable 331 can be moved along the adjusting screw 320 until the clamping turntable 331 and the movable knife seat 340 on the knife shaft 230 that is farthest from the fixed knife seat 231 are aligned.

[0030] The connecting clamp 332 is rotated along the rotating circular groove 333 until the connecting clamp 332 is clamped to the limiting groove 341, and the adjusting screw 320 is rotated again. The thrust generated by the rotation of the adjusting screw 320 on the clamping turntable 331 is transmitted to the movable knife seat 340 through the connecting clamp 332, and finally the movable knife seat 340 can be clamped and pressed against the fixed knife seat 231. After the position of the movable knife seat 340 relative to the knife shaft 230 is fixed by the adjusting assembly 330, the holding screw 343 on the movable knife seat 340 at the end of the knife shaft 230 can be tightened. After the movable knife seat 340 is fixed, the connecting clamp 332 and the adjusting screw 320 can be disassembled in sequence, and the knife wheel 200 can be sleeved on the movable knife seat 340 to cut the silicon steel sheet.

[0031] During the use of the above-mentioned silicon steel sheet cutting machine 100, there are multiple movable tool seats 340 on the tool shaft 230, and they can be detachably connected to the movable tool seats 340 through the connecting clamps 332 in the adjustment assembly 330. The position of the movable tool seats 340 relative to the tool shaft 230 is changed by the clamping turntable 331 and the adjusting screw 320, thereby changing the position of the cutter wheel 200 on the tool shaft 230 to achieve the adjustment of the silicon steel sheet cutting position.
