[0021] 1. The utility model sets a plurality of connection points for preventing deformation in the length direction of each magnetic isolation groove during the laser cutting and forming process of the magnetic isolation groove of the pulling plate, the spacing between the connection points is 350-450mm, the length of the connection point itself is 5mm, the connection point position of each magnetic isolation groove is the same, and the connection points in the magnetic isolation groove are cut off after the pulling plate is cut as a whole, so there is no need to reshape the pulling plate, the production efficiency is high, the processing cycle is short, and the product quality is easy to guarantee;

[0022] 2. In the utility model, the relevant technical personnel push the core pull plate to the installation position. At this time, the relevant technical personnel drive the lead screw to rotate in the horizontal direction through the driving motor. The lead screw pushes the first push plate threadedly connected thereto to perform linear movement in the horizontal direction. The first push plate drives the resistance component to push the core pull plate. At this time, the core pull plate performs linear movement in the horizontal direction under the limit of the limit component. At this time, the cutting component realizes the technical effect of cutting off the inter-slot connection points provided on the core pull plate for supporting the core pull plate by prompting the rotating cutting knife installed thereon to be inserted into the magnetic isolation groove of the core pull plate. At the same time, the lead screw can drive the third rotating shaft to rotate in the horizontal direction through the transmission pair. The third rotating shaft drives the worm to rotate synchronously. The worm drives the second rotating shaft to rotate in the vertical direction through the worm gear meshing therewith. The second rotating shaft drives the grinding cylinder to rotate in the vertical direction to achieve the technical effect of grinding and removing burrs on the side of the core pull plate.

[0023] 3. Since the guide block is a right triangle and its inclined side faces the outside of the device body, the relevant technicians can push the core pull plate to squeeze the guide block. At this time, the guide block pushes the second push plate to perform linear motion in the vertical direction along the limiting slide groove on the first push plate, that is, at this time, the guide block is located above the core pull plate until the core pull plate reaches the preset position. At this time, the guide block is reset, and the side edge of the second push plate contacts the end of the core pull plate. Under the push of the first push plate, the second push plate performs linear motion in the horizontal direction, that is, it can push the core pull plate to perform linear motion in the horizontal direction;

[0024] 4. The motor drives the fourth shaft to rotate in the horizontal direction through the coupling, and the fourth shaft drives the cutting knife to rotate in the horizontal direction. At this time, the first linear motion member drives the cutting knife to move linearly in the vertical direction by pushing the second mounting frame, prompting the cutting knife to be inserted into the magnetic isolation slot. At this time, since the core pull plate moves linearly in the horizontal direction under the limit of the limit assembly, in this embodiment, the cutting assembly provided can cut the connection points between the slots.
