Specific embodiments

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4 As shown, a rotor iron sheet stamping device for fan production includes a bottom plate 1;

[0024] A support frame 4 is fixedly connected to the top of the bottom plate 1. Buffer components 5 are arranged on both the left and right sides inside the support frame 4. A stamping plate 6 is arranged between the two buffer components 5. A limiting component 8 is arranged at the bottom of the stamping plate 6. A stamping head 10 is fixedly installed at the center of the bottom of the stamping plate 6. A through hole 9 is formed at the center of the top of the support frame 4. A hydraulic cylinder 7 is fixedly installed at the top of the support frame 4. The bottom end of the hydraulic cylinder 7 penetrates through the through hole 9 and is fixedly connected to the top of the stamping plate 6. A placement groove 2 is formed in the top of the bottom plate 1. A clamping component 3 is arranged inside the placement groove 2. During operation, first, the bottom of the bottom plate 1 is fitted to a flat ground to make the device stable. After the device is placed stably, the rotor iron sheet to be stamped is placed inside the placement groove 2 and pre-fixed by the clamping component 3. Then, the hydraulic cylinder 7 works to drive the stamping plate 6 and the stamping head 10 to move to stamp the rotor iron sheet. During the movement of the stamping plate 6, buffering is carried out through the buffer component 5 to avoid over-stamping. Immediately during stamping, the limiting component 8 makes the rotor iron sheet to be stamped keep its position stable, and cooperates with the pre-fixation of the clamping component 3 to make the position of the rotor iron sheet more stable, and avoid the rotor iron sheet from shifting during the stamping process, which affects the stamping quality. Thus, the device is convenient to use and has strong practicability.

[0025] The limiting component 8 includes a plurality of through holes 804 that are evenly distributed and opened inside the stamping plate 6. A guide rod 805 penetrates and slides inside the through hole 804. A limiting ring 801 is fixedly connected to the bottom end of the guide rod 805. A plurality of evenly distributed limiting springs 803 are fixedly connected between the limiting ring 801 and the stamping plate 6, and the limiting springs 803 are sleeved on the outer surface of the guide rod 805. A limiting pad 802 is fixedly connected to the bottom of the limiting ring 801. During operation, when the stamping plate 6 moves to drive the stamping head 10 to stamp, the movement of the stamping plate 6 drives the limiting plate and the limiting pad 802 to move. And the limiting pad 802 first fits with the rotor iron sheet inside the placement groove 2. During the continuous movement of the stamping plate 6, the limiting pad 802 drives the limiting plate to move and squeezes the limiting spring 803. When the limiting plate moves, it is limited by the sliding connection between the guide rod 805 and the through hole 804. Then, after the limiting spring 803 is squeezed, it has a rebounding force, so that the limiting plate and the limiting pad 802 squeeze and limit the rotor iron sheet to be stamped inside the placement groove 2, and make the rotor iron sheet to be stamped keep its position stable during stamping and not shift, so as not to affect the subsequent stamping quality, and make the device have a good use effect.

[0026] The limiting pad 802 is made of rubber material and corresponds to the placement groove 2. During operation, the limiting pad 802 made of rubber material has a good anti-slip effect and is convenient for the limiting pad 802 to move into the placement groove 2 to limit the rotor iron sheet.

[0027] The buffer assembly 5 includes limiting grooves 501 formed on the left and right sides inside the support frame 4. A limiting block 504 is slidably connected inside the limiting groove 501, and the opposite sides of the two limiting blocks 504 are respectively fixedly connected to the left and right sides of the stamping plate 6. A buffer spring 502 is fixedly connected between the bottom of the limiting block 504 and the lower surface inside the limiting groove 501. A limiting rod 503 is fixedly connected between the upper and lower surfaces inside the limiting groove 501. A vertically penetrating limiting hole 505 is formed at the center of the limiting block 504, and the top end of the limiting rod 503 penetrates through the buffer spring 502 and the limiting hole 505. During operation, the movement of the stamping plate 6 drives the limiting block 504 to slide inside the limiting groove 501, making the movement of the stamping plate 6 stable. At the same time, when the limiting block 504 slides, it is limited by the sliding connection between the limiting rod 503 and the limiting hole 505. After the limiting block 504 slides, it squeezes the buffer spring 502, and the rebounding force of the buffer spring 502 buffers the movement and stamping of the stamping plate 6 and the stamping head 10, thereby preventing over-stamping during movement.

[0028] The clamping assembly 3 includes threaded holes 303 formed on the front and rear surfaces inside the placement groove 2 and penetrating through. A threaded rod 302 is threadedly connected inside the threaded hole 303. The end of the threaded rod 302 is provided with a clamping plate 304 inside the placement groove 2. A groove 305 is formed on the side of the clamping plate 304 away from the center of the inside of the placement groove 2. A rotating rod 306 is rotatably connected inside the groove 305 through a bearing, and the end of the rotating rod 306 is fixedly connected to the end of the threaded rod 302. During operation, by rotating the threaded rod 302, the threaded rod 302 rotates and moves inside the threaded hole 303, and the rotational movement of the threaded rod 302 drives the clamping plate 304 to move downward under the limitation of the rotational connection between the rotating rod 306 and the groove 305. Then, after the clamping plate 304 moves, it can clamp and pre-fix the rotor iron sheet to be stamped placed inside the placement groove 2. When the stamping is completed, rotating the threaded rod 302 again makes the clamping plate 304 release the clamping of the rotor iron sheet, and then the stamped rotor iron sheet can be taken out from inside the placement groove 2.

[0029] One end of the threaded rod 302 away from the center of the inside of the placement groove 2 penetrates through the outer surface of the bottom plate 1 and is fixedly connected to a handle 301. During operation, the handle 301 facilitates the rotation of the threaded rod 302.
