Description
Technical Field
[0001] The utility model relates to the technical field of stator and rotor mold equipment, and more specifically, to a stator and rotor stamping mold. Background Art
[0002] A stamping die is a process equipment used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the required parts. When processing stator and rotor parts, the machined stator and rotor are generally not fixed on the die. When the two dies are completed and separated from each other, they often cause the stator and rotor to move, causing them to fall between the two dies, affecting the collection of the finished stator and rotor products. Utility Model Content
[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a stamping die for fixing and limiting the stator and rotor.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stator and rotor stamping die, comprising a die body, the body comprising a support rod for supporting the stator and rotor, characterized in that: the support rod is provided with a limit device and has a limit cavity matching the limit device, the limit cavity comprises a first opening and a second opening, the limit device comprises a limit piece, a push piece and a reset piece, the limit piece is placed in the limit cavity to slide and slide out from the first opening, the push piece extends into the limit cavity from the second opening to slide and conflicts with the limit piece, the push piece drives the limit piece to slide back into the limit cavity, the reset piece is fixed in the limit cavity to slide and conflicts with the limit piece, and the reset piece pushes the limit piece to extend out of the limit cavity.
[0005] A further solution is: the limit member includes a limit block, a rotating rod and a rotating cylinder, the limit block is placed in the limit cavity to slide and slide out from the first opening to conflict with the stator and rotor, the limit block has a limit slot, the rotating rod is placed in the limit slot and is rotatably connected to the limit block, the rotating cylinder is sleeved on the rotating rod and fixedly connected to the rotating rod, and the pushing member and the reset member both extend into the limit slot and conflict with the rotating cylinder.
[0006] A further solution is: the pushing member includes a pushing block, a limiting rod, a first spring and a reset plate, the pushing block extends from the second opening into the limiting cavity, slides and extends into the limiting groove to conflict with the rotating cylinder, the limiting rod is fixed in the limiting cavity, the pushing block is provided with a sliding groove that cooperates with the limiting rod, a reset groove is provided on the inner side wall of the limiting cavity, the reset plate is fixed on the pushing block and extends into the reset groove, the first spring is fixed in the reset groove and is fixedly connected to the reset plate.
[0007] A further solution is: the reset member includes a reset block and a second spring, the reset block is placed in the limiting cavity to slide and slide into the limiting groove to conflict with the rotating cylinder, the reset block is symmetrically placed around the rotating cylinder and the pushing block, the second spring is fixed in the limiting cavity and fixedly connected to the reset block, and the second spring pushes the reset block to extend into the limiting groove to conflict with the rotating cylinder.
[0008] A further solution is that the surfaces of the push block and the reset block extending into the limit slot and contacting the rotating cylinder are both inclined.
[0009] By adopting the above technical solution, the limit block extending from the first opening of the limit cavity will conflict with the stator and rotor sleeved on the support rod, so that the stator and rotor are placed on the support rod and cannot move, thereby preventing the stator and rotor from falling from the support rod. By pressing the pushing block, the limit block can be driven to slide and slide back into the limit cavity through the conflict between the pushing block and the rotating cylinder, so that the stator and rotor on the support rod are in a movable state, and the formed stator and rotor can be removed from the mold, and the pushing block can be released. Under the elastic action of the first spring and the second spring, the pushing block can be reset and the limit block can be pushed out of the support rod again to limit and fix the stator and rotor again.

DETAILED DESCRIPTION
[0016] Reference Figures 1 to 5 A stator and rotor stamping die embodiment of the utility model is further described.
[0017] A stator and rotor stamping die comprises a die body 1, the body 1 comprises a support rod 2, the support rod 2 is fixed on the body 1, the support rod 2 is used to support the stator and rotor, and the corresponding holes on the stator and rotor are put on the support rod 2, so that the stator and rotor can be fixed relative to the body 1, and the stator and rotor can be stamped. The support rod 2 is provided with a limiting device 3 and a limiting cavity 4 matched with the limiting device 3, the limiting cavity 4 comprises a first opening 5 and a second opening 6, the first opening 5 can be opened at the side wall of the support rod 2 and matched with the position of the stator and rotor, the second opening 6 can be opened at the end of the support rod 2, and the limiting device 3 comprises a limiting member 7, a pushing member 8 and a reset member 9.
[0018] The limiting member 7 comprises a limiting block 10, a rotating rod 11 and a rotating cylinder 12. The limiting block 10 can be placed in the limiting cavity 4 and slide, and can slide out of the limiting cavity 4 from the first opening 5, that is, extend the support rod 2. The limiting block 10 extending out of the first opening 5 can conflict with the stator and rotor sleeved on the support rod 2, thereby limiting the movement of the stator and rotor placed on the support rod 2, and preventing the stator and rotor from falling from the mold. The limiting block 10 has a limiting groove 13, and the rotating rod 11 is placed in the limiting groove 13 and the two ends of the rotating rod 11 are rotatably connected to the inner side wall of the limiting groove 13, that is, the rotating rod 11 is rotatably connected to the limiting block 10, so that the rotating rod 11 can be placed in the limiting groove 13 and rotate. The rotating cylinder 12 is sleeved on the rotating rod 11 and the inner side wall of the rotating cylinder 12 can be welded and fixed to the outer side wall of the rotating rod 11, so that the rotating cylinder 12 can be placed in the limiting groove 13 and rotate together with the rotating rod 11.
[0019] The push member 8 includes a push block 14, a limiting rod 15, a first spring 16 and a reset plate 17. The push block 14 can be extended into the limiting cavity 4 through the second opening 6 and placed in the limiting cavity 4 to slide. The push block 14 extended into the limiting cavity 4 can simultaneously extend into the limiting groove 13 and conflict with the rotating cylinder 12, pushing the push block 14 placed outside the support rod 2. Through the conflict between the push block 14 and the rotating cylinder 12, the limiting block 10 can be driven to slide and slide back into the limiting cavity 4, so that The limiting block 10 is disconnected from the stator and rotor sleeved on the support rod 2, so that the stator and rotor are in a movable state, so that the finished stator and rotor can be actively removed from the mold. The two ends of the limiting rod 15 can be fixed on the inner wall of the limiting cavity 4. The push block 14 is provided with a sliding groove 18. The limiting rod 15 can penetrate the sliding groove 18. The sliding groove 18 can extend in the sliding direction of the push block 14, so that when the push block 14 slides, the limiting rod 15 can be placed in the sliding groove 18. The inner sliding, the interference between the limit rod 15 and the inner side wall of the sliding groove 18 can make the pushing block 14 always remain in the state of extending into the limit groove 13, and can also prevent the limit block 10 from completely sliding out of the limit cavity 4. In addition, it can also prevent the pushing block 14 from sliding out of the limit cavity 4, ensuring the effective implementation of the pushing block 14. A reset groove 19 is opened on the inner side wall of the limit cavity 4, and the reset plate 17 can be bonded and fixed to the pushing block 14 and the reset plate 17 can extend into the reset groove 19. The reset plate 17 can follow the sliding of the pushing block 14 and be placed in the reset groove 19 to slide. One end of the first spring 16 can be fixed in the reset groove 19, and the other end of the first spring 16 can be fixedly connected to the reset plate 17. The first spring 16 can use its own elasticity to push the reset plate 17 to slide, that is, to push the pushing block 14 to slide, and push the pushing block 14 that originally slid into the limit cavity 4 back to the initial state, so that the limit block 10 is not affected by the pushing block 14 and is in a state where the support rod 2 can be extended.
[0020] The reset member 9 includes a reset block 20 and a second spring 21. The reset block 20 is placed in the limit cavity 4 and slides and can slide into the limit groove 13 and conflict with the rotating cylinder 12. The reset block 20 is symmetrically placed around the rotating cylinder 12 and the push block 14, so that the reset block 20 pushes the limit block 10 in the opposite direction to the push block 14. One end of the second spring 21 can be fixed in the limit cavity 4, and the other end of the second spring 21 can be fixedly connected to the reset block 20. The second spring 21 can use its own elasticity to push the reset block 2 0 slides into the limiting slot 13 and maintains the interference with the rotating cylinder 12. When the pushing block 14 is restored to the initial position by the action of the first spring 16, the reset block 20 can push the limiting block 10 to slide and slide out of the support rod 2 through the elastic action of the second spring 21, so that the limiting block 10 performs the limiting effect, ensuring the re-implementation of the limiting block 10. In addition, the reset block 20 always extends into the limiting slot 13 to further prevent the limiting block 10 from completely sliding out of the limiting cavity 4, ensuring the effective implementation of the limiting block 10.
[0021] The surfaces of the push block 14 and the reset block 20 that extend into the limiting groove 13 and contact the rotating cylinder 12 can be inclined slopes, so that the push block 14 and the reset block 20 are more convenient and efficient when pushing the limiting block 10 to slide. In addition, when the push block 14 and the reset block 20 contact the rotating cylinder 12, the inclined surface can drive the rotating cylinder 12 to rotate, thereby reducing the friction between the push block 14 and the reset block 20 and the rotating cylinder 12, ensuring the long-term and efficient implementation of the entire limiting device 3.
[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
