With the cooperation of the lead screw 13 and the lead screw nut 14, the drive plate is raised and lowered along the smooth rod 16. When the drive plate descends, it guides the connecting rod 26 through the second strip-shaped through groove, so that the mounting base 23 moves at equal intervals to both ends of the guide rod 22. The connecting plate 25 is clamped and installed between the two sets of clamping plates, so that the auxiliary ring cutting disc 4 moves synchronously with the mounting base 23.

[0031] In use, the clamping disc 41 is locked by tightening the locking nut 44. The balls 46 on the clamping disc 41 are in close contact with the ring cutter 8 and the connecting plate 25. The control plate 11 is raised and lowered by the third motor 18, so that the mounting base 23 moves at equal intervals along the guide rod 22. Under the action of the connecting plate 25, the auxiliary ring cutting disc 4 moves synchronously with the mounting base 23, thereby realizing the position adjustment of the cutter. During processing, the steel coil passes between the ring cutter 8 and the auxiliary ring cutting disc 4 under the drive of the conveying equipment (not shown in the figure). The first motor 6 and the second motor 10 drive the first drive shaft 3 and the second drive shaft 7 to rotate in opposite directions, respectively. The ring cutter 8 cuts the steel coil. Under the action of the clamping disc 41, the ring cutter 8 reduces the vibration generated during the cutting process, thereby avoiding the steel coil from curling and improving the production quality of the steel coil.
