[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figure 1 - Figure 2 In an embodiment provided by the present utility model: A slot punching device for the core of a disc motor includes a workbench 1. A placing groove 2 is fixedly connected to the top of the workbench 1. The placing groove 2 is arranged directly below the stamping equipment. Support legs 3 are fixedly connected to the top of the workbench 1. A mounting frame 4 is fixedly connected to the top of the support legs 3. An electric cylinder is arranged in the middle of the mounting frame 4 to drive the upper part of the stamping mechanism 5 to work. This is the prior art and will not be elaborated here. A stamping mechanism 5 is arranged at the bottom of the mounting frame 4. An adjusting mechanism 6 is arranged on the top of the workbench 1;

[0028] Refer to Figure 6 - Figure 7, the adjusting mechanism 6 includes a fixed chassis 601, a spring rod 602, a fixed sleeve 603, a threaded rotating rod 604, a rotating disk 605, a sliding disk 606, and a sliding seat 607. The fixed chassis 601 is fixedly connected to the top of the workbench 1. The spring rod 602 is fixedly connected to the top of the fixed chassis 601. When the upper punching equipment works, the spring rod 602 produces partial buffering effect to prevent the iron core from being damaged by large impact stress during punching. The fixed sleeve 603 is fixedly connected to the inner wall of the workbench 1. A rotating spiral groove is provided on the inner wall of the fixed sleeve 603. The threaded rotating rod 604 is threadedly connected to the inner wall of the fixed sleeve 603. The rotating disk 605 is fixedly connected to the bottom of the threaded rotating rod 604. The rotating disk 605 drives the threaded rotating rod 604 to rotate and rise along the inner wall of the fixed sleeve 603. The sliding disk 606 is slidably connected to the inside of the placement groove 2. The sliding seat 607 is fixedly connected to the top of the threaded rotating rod 604.

[0029] Refer to Figure 6 - Figure 7 , the adjusting mechanism 6 further includes a connecting block 608, an inclined rod 609, and a struck plate 610. The connecting block 608 is fixedly connected to the top of the workbench 1. The inclined rod 609 is rotatably connected to the inner wall of the connecting block 608 through a connecting rod. During the downward movement of the linkage rod 508, it contacts the inclined rod 609, causing the inclined rod 609 to incline along the inner wall of the connecting block 608. The struck plate 610 is fixedly connected to the left side of the placement groove 2. Both the struck plate 610 and the placement groove 2 are made of metal and are fixedly connected to each other. The left side of the fixed chassis 601 is fixedly connected to the inner wall of the placement groove 2. When the upper pressing assembly retracts, the inclined rod 609 loses the pressure exerted by the linkage rod 508, causing the inclined rod 609 to reset through a torsion spring and strike the surface of the struck plate 610, causing the struck plate 610 to vibrate and transmit to the placement groove 2. One end of the spring rod 602 away from the fixed chassis 601 is fixedly connected to the bottom of the sliding seat 607. The left side of the sliding seat 607 is slidably connected to the inner wall of the placement groove 2. The sliding seat 607 is located on the movement track of the sliding disk 606. The rear part of the connecting block 608 contacts the front part of the inclined rod 609. The bottom of the struck plate 610 contacts the top of the struck plate 610. Thus, after punching, the waste or debris remaining in the iron core groove can be discharged through vibration.

[0030] Refer to Figure 3 - Figure 5, the stamping mechanism 5 includes an electric telescopic rod 501, a connecting frame 502, a telescopic rod 503, a transmission block 504, a connecting square frame 505, a spring pressing rod 506, an L-shaped cutter 507, and a linkage rod 508. The electric telescopic rod 501 is fixedly connected to the inner wall of the mounting frame 4. The electric telescopic rod 501 drives the connecting frame 502 to move downward and is connected to the previous electric cylinder. The connecting frame 502 is fixedly connected to the bottom of the electric telescopic rod 501. The telescopic rod 503 is slidably connected to the inner wall of the connecting frame 502 through a spring. The transmission block 504 is fixedly connected to the bottom of the telescopic rod 503. The connecting frame 502 drives the telescopic rod 503 and the transmission block 504 to move downward. The connecting square frame 505 is fixedly connected to one end of the telescopic rod 503 away from the transmission block 504. The spring pressing rod 506 is slidably connected to the inner wall of the connecting frame 502 through a spring. The connecting square frame 505 at the top of the telescopic rod 503 moves downward. During the downward movement of the connecting square frame 505, it collides with the spring pressing rod 506. The L-shaped cutter 507 is fixedly connected to one end of the spring pressing rod 506 away from the connecting square frame 505. The linkage rod 508 is fixedly connected to the left side of the connecting frame 502. The spring pressing rod 506 drives the bottom L-shaped cutter 507 to expand downward. During the process of pressing and stamping the housing raw material inside the placement groove 2, the L-shaped cutter 507 first cuts the edge of the iron core groove during stamping to remove any excess material or minor defects that may appear on the edge of the iron core groove.

[0031] Refer to Figure 3 - Figure 5 , the stamping mechanism 5 further includes a vertical block 509, a striking rod 510, a striking head 511, a stress rod 512, a retractable rod 513, a retractable plate 514, and a protection box 515. The protection box 515 is fixedly connected to the bottom of the connecting frame 502. The vertical block 509 is fixedly connected to the top wall inside the protection box 515. The striking rod 510 is rotatably connected to the inner wall of the vertical block 509 through a connecting rod. The striking rod 510 rotates in the inner wall of the vertical block 509 through a torsion spring. The striking head 511 is fixedly connected to the right side of the striking rod 510. The striking head 511 strikes the retractable plate 514 to prevent the upper stamping component from taking the iron core out of the mold after stamping. The stress rod 512 is fixedly connected to the bottom of the striking rod 510. The retractable rod 513 is fixedly connected to the top wall inside the protection box 515. The retractable plate 514 is fixedly connected to the bottom of the retractable rod 513. During the downward pressing process, the retractable plate 514 comes into contact with the iron core for the first time. The bottom of the connecting square frame 505 is in contact with the top of the spring pressing rod 506. The linkage rod 508 is installed on the movement track of the inclined rod 609. The rear part of the vertical block 509 is in contact with the front part of the striking rod 510. The retractable plate 514 is installed on the movement track of the striking head 511. The bottom of the stress rod 512 is installed on the movement track of the retractable plate 514.

[0032] Working principle: During use, place the iron core to be stamped into the interior of the placement groove 2. At this time, the operator activates the electric telescopic rod 501. The electric telescopic rod 501 drives the connecting frame 502 to move downward. The connecting frame 502 drives the telescopic rod 503 and the transmission block 504 to move downward, causing the connecting square frame 505 at the top of the telescopic rod 503 to move downward. During the downward movement of the connecting square frame 505, it collides with the spring pressing rod 506, causing the spring pressing rod 506 to drive the bottom L-shaped cutting knife 507 to expand downward. During the process of pressing and stamping the housing raw material inside the placement groove 2, the L-shaped cutting knife 507 first cuts the edge of the iron core groove of the stamping, removing any excess material or minor defects that may appear at the edge of the iron core groove, improving the overall quality and reliability of the iron core groove. The transmission block 504 comes into contact with the placement groove 2, causing the transmission block 504 to move in the reverse direction. The transmission block 504 drives the telescopic rod 503 to be jacked up in the reverse direction, causing the spring on its surface to contract and compress, and causing the connecting square frame 505 to rise. At this time, the L-shaped cutting knife 507 is reset by the force of the spring of the spring pressing rod 506, causing the L-shaped cutting knife 507 to retract. When the electric telescopic rod 501 drives the upper part of the component to retract, at this time, the telescopic rod 503 and the transmission block 504 are reset under the action of the spring, and the iron core groove on the surface of the upper pressing component is ejected, preventing it from being taken out of the placement groove 2 by the upper pressing component. At the same time, the retractable plate 514 retracts into the interior of the protection box 515 during the pressing process. During the retraction process of the retractable plate 514, it comes into contact with the force-bearing rod 512. The force-bearing rod 512 drives the striking rod 510 to tilt, and causes the striking head 511 to strike the retractable plate 514, further preventing the stamped iron core groove from getting stuck on the upper pressing component. When the operator needs to adjust the depth of the iron core groove during production, at this time, the operator can rotate the rotating disk 605. The rotating disk 605 drives the threaded rotating rod 604 to rotate along the inner wall of the fixed sleeve 603, causing the threaded rotating rod 604 to drive the sliding seat 607 to move up and down inside the placement groove 2 for adjustment. When the upper pressing component applies pressure, when the sliding disk 606 moves downward, it is limited by the sliding seat 607. Thus, by changing the height of the sliding seat 607 inside the placement groove 2, the height at which the sliding disk 606 is compressed and lowered can be changed, achieving the function of adjusting the thickness of the stamped iron core groove. At the same time, the connecting frame 502 drives the linkage rod 508 to move downward, causing the linkage rod 508 to come into contact with the inclined rod 609 during the downward movement, causing the inclined rod 609 to tilt along the inner wall of the connecting block 608. When the upper pressing component retracts, the inclined rod 609 loses the pressure applied by the linkage rod 508, causing the inclined rod 609 to be reset by the torsion spring and strike the surface of the struck plate 610, causing the struck plate 610 to vibrate and conduct the vibration to the placement groove 2, causing the placement groove 2 to vibrate, which is conducive to discharging the waste materials or debris remaining in the iron core groove during the stamping process, ensuring the cleanliness of the iron core groove.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
