[0002] With the rapid development of industrial automation and motor manufacturing technology, the motor stator, as one of the core components, directly affects the performance and market competitiveness of motor products through the precision and efficiency of its production process. In the motor stator manufacturing process, the keyway punching of blanked circular blanks is one of the key processes.

[0003] Traditional blanking equipment for circular wafers is generally designed using a "dedicated machine for a specific purpose" model, meaning each machine can only handle the blanking needs of stator circular wafers within a specific diameter range. To cover a full range of product sizes, factories need to purchase multiple blanking machines of different specifications. Each machine includes an independent frame, stamping system, positioning fixtures, and control system, leading to an exponential increase in equipment procurement costs. Furthermore, energy consumption, maintenance, and labor costs increase significantly when multiple machines operate in parallel. In addition, each blanking machine requires independent operating space, material handling channels, and safety protection areas, resulting in low utilization of factory space. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see the appendix Figure 1-6 This embodiment discloses a stamping device for keyway blanking of motor stator blanking discs: it includes a base 1, a stamping table 2 fixedly connected to the side of the base 1, a hydraulic punch 3 slidably connected to the stamping table 2, a slide rail 4 provided on the side of the stamping table 2, the slide rail 4 being fixedly connected to the base 1, a carrying platform 5 slidably connected to the slide rail 4, a support platform 6 fixedly connected to the carrying platform 5, a rotating suction platform 7 rotatably connected to the support platform 6, a plurality of pallets 8 provided on the outer side of the rotating suction platform 7, the top surface of the pallets 8 being flush with the top surface of the rotating suction platform 7, and an adjustment component 9 connected below the pallets 8, the adjustment component 9 controlling the plurality of pallets 8 to synchronously spread outward or converge inward.

[0023] Base 1 is the bottom support component, and both the punching table 2 and the worktable 5 are mounted on base 1. Figure 1As shown, the blanking table 2 is located on the right side of the base 1, the platform 5 is slidably mounted on the left side of the blanking table 2, and the hydraulic punch 3 is located directly above the blanking table 2. The hydraulic punch 3 is the blanking part of the press. Other components connected to the hydraulic punch 3 have the same structure as existing presses, and no improvements are made to these parts in this application. They will not be described in detail here. The hydraulic punch 3 and the blanking table 2 are the blanking parts of the blanking disc. The rotating suction table 7 and the tray 8 on the support platform 6 are the positioning support parts for the blanking disc. The support platform 6 is located above the platform 5. The rotating suction table 7 is raised to a position flush with the blanking table 2 by the support platform 6. At the same time, the top surface of the rotating suction table 7 and the top surface of the tray 8 are at the same height. This ensures that the bottom of the blanking disc is level after it is placed, ensuring the accuracy of the subsequent keyway blanking. The slide rail 4 in this application is an electromagnetic slide rail 4. The platform 5 can slide left and right on the slide rail 4 and move to... Its position is locked. The left and right movement of the platform 5 can drive the support platform 6, the rotating suction platform 7 and the pallet 8 to move synchronously. After the rotating suction platform 7 moves to the left, the horizontal straight distance from the center of the rotating suction platform 7 to the hydraulic punch 3 will increase. At this time, the rotating suction platform 7 can carry a motor stator with a larger diameter, and the hydraulic punch 3 can perform punching operations on larger blanking discs. In order for the device to provide bottom support for blanking discs of different sizes, multiple pallets 8 around the rotating suction platform 7 can be adjusted. Multiple pallets 8 move synchronously. When the blanking disc is larger, multiple pallets 8 expand outward synchronously, and vice versa. The rotating suction platform 7 has a locking pin with a round hole in the middle. Electromagnetic fixing blocks are provided around the locking pin. The rotating suction platform 7 positions the blanking disc through the locking pin and the electromagnetic fixing blocks, and drives the blanking disc to rotate during the keyway punching process, thereby improving the efficiency of automatic blanking disc punching.

[0024] like Figure 1 and Figure 3 As shown, there are five pallets 8, each with a 60-degree arc structure, spaced 60 degrees apart. A notch is provided on the left side of the cutting table 2 to prevent interference between the pallets 8 and the cutting table 2. The five pallets are synchronously driven by an adjusting assembly 9. The telescopic rod 905 within the adjusting assembly 9 is a hydraulic rod, and its extension or retraction is controlled by a hydraulic system. Figure 2 and Figure 5As shown, when the telescopic rod 905 moves the sliding sleeve 904 towards the support platform 6, the sliding sleeve 904 moves the bottom of the connecting rod 903 upward. The upward movement of the connecting rod 903 causes the guide rod 901 to move away from the center of the support sleeve along the sliding groove 902. The five guide rods 901 move synchronously, thereby causing the five trays to move away from the center of the support platform 6 synchronously. The support space enclosed by the five trays 8 becomes larger, and the device can support larger motor stators. Conversely, when the telescopic rod 905 retracts, the five trays 8 retract inward synchronously, and the support space becomes smaller.

[0025] The rotating adsorption table 7 is driven by the drive shaft 11 below. The drive shaft 11 passes through the sliding sleeve 904 and the support table 6 and is connected to the loading table 5 below. The loading table 5 has a cavity, in which a gap drive component is installed. This gap drive component cooperates with the hydraulic punch 3 to rotate the drive shaft 11 at a specific angle after punching and to keep the drive shaft 11 fixed during the punching process. This type of gap drive component has been used in existing punching devices and is considered prior art, so it will not be described in detail here. The support table 6 is supported by six support columns 10. The six support columns 10 are staggered with the connecting rod 903. The support of the support columns 10 will not interfere with the movement of the connecting rod 903.

[0026] The size of the inner punch head 302 of the hydraulic punch 3 is the same as the size of the blanking disc. The punch head 302 is installed on the punching plate 301 by fixing bolts. When punching blanking discs of different specifications, the corresponding punch head 302 can be directly replaced. The limiting rod 304 plays a guiding role for the sleeve 303. During the vertical punching process of the punching plate 301, the sleeve 303 is always located inside the limiting rod 304. This ensures the vertical correspondence between the punch head 302 and the punch hole 12, ensures the punching accuracy of the blanking keyway, and improves the punching efficiency.

[0027] Furthermore, to ensure that the blanking disc does not deform during the punching process, a pressure plate 305 is installed below the punching head 302. In the initial state, the spring 308 exerts a downward force on the pressure plate 305, and the lowest point of the pressure plate 305 is lower than the bottom of the punching head 302. When the punching plate 301 moves downward, the pressure plate 305 presses the blanking disc. After the blanking disc is pressed and fixed, the punching head 302 will pass through the circular hole to punch the blanking disc. The pressure plate 305 is slidably connected to the punching plate 301 through the guide pin 306. The limiting piece 307 at the upper end of the guide pin 306 prevents the guide pin 306 from disengaging from the punching plate 301. The guide pin 306 in the middle of the spring 308 can prevent the spring 308 from bending due to excessive compression.

[0028] like Figure 6As shown, the punching table 2 has punch holes 12 and a discharge chute 13. The punch holes 12 are located below the hydraulic punch 3. The scrap material to be punched enters the discharge chute 13 through the punch holes 12. The bottom of the discharge chute 13 is an inclined chute. The scrap material flows out of the punching table 2 by gravity in the inclined chute. A scrap conveyor belt can be set at the discharge inlet of the discharge chute 13 to automatically transfer the scrap material and improve the automation level of the production line.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
