[0023] In this embodiment, a slide groove 8 with a length equal to that of the threaded rod 2 is opened on the inner side wall of the upper mold 1, and a slider 9 is provided in the slide groove 8. The top surface of the slider 9 is fixedly connected to the bottom surface of the driven block 3. The slider 9 can make the threaded rod 2 rotate and drive the driven block 3 to move more smoothly.

[0024] In this embodiment, a passage groove 10 is opened at the two side walls of the upper mold 1 corresponding to the clamping position of the driven clamp 6, and fixed plates 11 are symmetrically provided at both ends of the passage groove 10. A rotating roller 12 is provided between the two side fixed plates 11, and a roller sleeve 13 is provided on the rotating roller 12. The roller sleeves 13 on both sides can limit the iron core plate to a horizontal state and fix the iron core plate without external force.

[0025] In this embodiment, servo motors 14 are provided at the ends of the threaded rods 2 on both sides on the outer wall of the upper mold 1 , and the servo motors 14 are used to drive the threaded rods 2 to rotate.

[0026] In this embodiment, a plug-in frame 15 is provided on the inner wall of the upper mold 1 between the two side slide grooves 8. The plug-in frame 15 partially protrudes from the outer wall of the upper mold 1, and the protruding part is provided with two groups of threaded connection holes 16. The plug-in frame 15 is used to plug in the lower mold, and after plugging in, the screw can be screwed into the threaded connection hole 16 to fix it. After fixing, the top surface of the lower mold contacts the bottom surface of the iron chip plate.

[0027] In this embodiment, a support plate 17 is provided on the inner wall of the upper mold 1 above the slide groove 8, and a hydraulic telescopic rod 18 is fixedly provided on the top surface of the support plate 17. The end of the hydraulic telescopic rod 18 is fixedly connected to the top wall of the upper mold 1. The top surface of the upper mold 1 is in an active state that rises and falls with the extension and retraction of the hydraulic telescopic rod 18. After the hydraulic telescopic rod 18 contracts, the top surface of the upper mold 1 can be lowered, thereby lowering the punching machine 19 for blanking.

[0028] In this embodiment, the support plate 17 is higher than the driven clamp 6, and a punch 19 is provided in the middle of the top surface of the upper mold 1. The punch 19 is set through the support plate 17 and is higher than the driven clamp 6 so that the driven clamps 6 on both sides will not interfere with the support plate 17 after they are away from each other to the maximum distance.

When in use, the lower die can be plugged in through the plug-in frame 15, and then the screw can be screwed into the threaded connection hole 16 to lock the upper die 1 and the lower die. At the same time, the servo motors 14 on both sides simultaneously rotate the threaded rod 2 to make the driven blocks 3 approach each other until they are arranged at both ends of the lower die. At the same time, the long plate of the iron core sheet passes through between the roller sleeves 13 of the two sets of rotating rollers 12. When passing between the two sets of driven clamping blocks 6, the swing block 5 rotates to make the driven clamping blocks 6 approach each other under the guidance of the guide shaft 7 until they are clamped and fixed, and pass through the other side passage groove 10 to achieve the horizontal movement of the long plate of the iron core sheet. The hydraulic telescopic rod 18 contracts to make the punching machine 19 descend for punching. After the punching is completed, the left threaded rod 2 rotates to drive the driven block 3 to move, so that the iron core sheet plate can be pulled out to pull the cut part back and clamp it. Under the action of the roller sleeves 13 on both sides, the iron core sheet plate will not shift, thereby achieving separation from manual labor and avoiding accidents.
