The second bevel gear 303 is provided with a second bevel gear 304, and the second bevel gear 305 is provided with a second bevel gear 305. A second screw rod 303 is provided on the side of the gear 302 away from the first bevel gear 301, and a threaded block 304 is provided on the second screw rod 303. A moving rod 305 is provided at the top of the threaded block 304, and a cross bar 306 is provided on the moving rod 305. A through hole 311 is provided at the end of the cross bar 306 away from the moving rod 305, and an insertion rod 307 is provided at the top of the through hole 311. The top of the insertion rod 307 is connected to a limiting rod 308, and a pressing plate 309 is provided on the top of the limiting rod 308. A return spring 310 is provided between the bottom ends of both sides of the pressing plate 309 and the top of the cross bar 306.

[0035] The first bevel gear 301 is meshed with the second bevel gear 302, the lifting block 203 is connected to the nut of the first screw rod 202, the threaded block 304 is connected to the nut of the second screw rod 303, the connecting plate 409 and the connecting pipe 406 are both arranged in an "L" shape, and the blowing plate 407 is arranged in a rectangular shape.

[0036] A connecting block 8 is provided on the side of the processing table 1 close to the second screw rod 303, and a movable groove 801 is provided on the top of the connecting block 8. A movable groove 802 is provided on the side of the connecting block 8 close to the collecting box 401. The slot size of the movable slot 801 is consistent with the thickness size of the moving rod 305, and the slot size of the movable slot 802 is consistent with the thickness size of the connecting plate 409.

[0037] The limiting rod 308 and the inserting rod 307 are both arranged in a columnar shape. The diameter of the limiting rod 308 is larger than the diameter of the inserting rod 307. The size of the inserting rod 307 is consistent with the size of the through hole 311. The through hole 311 passes through the upper and lower ends of the cross bar 306.

[0038] The extension plate 206 is arranged at the top of the pressing plate 309, and a stamping docking hole 5 is provided in the middle of the top of the processing table 1. The stamping docking hole 5 passes through the processing table 1 and is connected to the collection box 401. A discharge port 702 is provided on the side of the processing table 1 close to the connecting block 8, and an insertion port 7 is provided on the side of the processing table 1 away from the discharge port 702. Both ends of the blank plate material 6 are connected to the insertion port 7 and the discharge port 702, and a support plate 701 is provided at the bottom end of the processing table 1 close to the insertion port 7.

[0039] In this embodiment, it should be noted that: the blank sheet 6 used for processing the motor stator and rotor punching sheets is inserted from the insertion port 7, and rollers are provided inside the processing table 1 and on both sides of the stamping docking hole 5 to assist the movement of the blank sheet 6. When the blank sheet 6 moves into the stamping docking hole 5, the driving motor 201 starts to drive the first screw rod 202 to rotate, so that the lifting block 203 connected to the nut of the first screw rod 202 and the lifting plate 204 move downward, driving the punching head 205 to approach the blank sheet 6 for stamping, so that the punched sheet falls into the top position of the filter plate 403 in the collection box 401 through the stamping docking hole 5.

[0040] When a new blank sheet 6 is just inserted into the processing table 1, the first two punching processing operations manually move the blank sheet 6. After the blank sheet 6 with the punching hole is moved out from the discharge port 702, when the driving motor 201 starts to drive the first screw rod 202 to rotate, it will drive the first bevel gear 301 and the second bevel gear 302 meshing therewith to rotate, and then drive the second screw rod 303 to rotate, so that the threaded block 304 connected to the nut of the second screw rod 303 moves horizontally on the second screw rod 303.

[0041] When the lifting plate 204 moves downward, the moving rod 305 drives the cross bar 306 to move horizontally to the side away from the processing table 1. When the cross bar 306 moves to the middle of the second screw rod 303, the lifting plate 204 is halfway down, and the bottom end of the extension plate 206 contacts the top of the pressing plate 309. As the lifting plate 204 continues to move downward, the reset spring 310 is squeezed and compressed, and the insertion rod 307 is passed through the through hole 311, and the insertion rod 307 is inserted into the hole-shaped position of the processing punch on the blank sheet 6. As the moving rod 305 continues to move, the insertion rod 307 moves outward against the punch hole, thereby driving the blank sheet 6 to move outward as a whole, and moving the unprocessed part on the blank sheet 6 to the position of the stamping docking hole 5, thereby realizing the stamping of the stamping head 205.

[0042] When the lifting plate 204 is reset, the reset spring 310 is reset, the insertion rod 307 moves out of the punching hole distance processed on the blank plate 6, and as the lifting plate 204 is reset, the moving rod 305 and the cross bar 306 are reset.

[0043] The columnar shape of the insert rod 307 can be inserted into the hole pitch shapes of different stator and rotor punchings, and cooperate with the movement of the threaded block 304 to push the blank sheet 6 outward without causing the blank sheet 6 to move up and down.

[0044] Embodiment 2:

[0045] Different from the first embodiment, Figure 1-2 , Figure 4 as well as Figure 6, this embodiment also has the following further contents: the dust removal component 4 is used to blow air to remove dust from the stamped sheets when the toggle component 3 is reset, and the dust removal component 4 includes a collection box 401, an inclined plate 402, a filter plate 403, a drop port 404, a folded corrugated cylinder 405, a connecting pipe 406, a blowing plate 407, a mesh cloth 408 and a connecting plate 409. The bottom end of the processing table 1 is provided with a collection box 401, and the middle of the collection box 401 is provided with a filter plate 403. The collection box 4 01 is provided inside and at the bottom end of the filter plate 403, and a falling port 404 is provided at the inclined end of the inclined plate 402. A connecting plate 409 is connected to the bottom end of the threaded block 304. A folding bellows 405 is provided on the side of the connecting plate 409 close to the processing table 1, and a connecting pipe 406 is provided on the end of the folding bellows 405 away from the connecting plate 409. A blowing plate 407 is provided on the end of the connecting pipe 406 away from the folding bellows 405, and a mesh cloth 408 is provided on the blowing plate 407.

[0046] The blowing plate 407 is arranged in an inclined shape and the inclination angle is consistent with the inclination angle of the inclined plate 402 .

[0047] In this embodiment, it should be noted that: when the punching head 205 is punching the blank sheet material 6, the moving rod 306 is away from one side of the processing table 1. At this time, the connecting plate 409 is away from the processing table 1, and the folded corrugated cylinder 405 is stretched and unfolded, so that a certain amount of air is stored inside the folded corrugated cylinder 405. When the punching is completed and the punched sheet falls on the filter plate 403, the lifting plate 204 drives the punching head 205 to reset while the threaded block 304 drives the moving rod 305 and the connecting plate 409 to reset close to the processing table 1. At this time, when the connecting plate 409 is close to the processing table 1, it will squeeze the folded corrugated cylinder 405, and blow the air inside the folded corrugated cylinder 405 outward through the connecting pipe 406 and the blowing plate 407, blowing the debris attached to the sheet, so that the debris is blown away from the sheet and falls through the filter plate 403 to the bottom of the collection box 401.

[0048] The blowing plate 407 and the inclined plate 402 are both inclined, so when the blowing plate 407 blows air, the debris falling on the inclined plate 402 will slide along the inclined surface of the inclined plate 402 and fall into the bottom of the collection box 401 from the drop port 404 for collection.
