Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] The brushless motor stator stamping die comprises a base 1. A groove 11 is provided on the top of the base 1 for installing a punch seat 12. The inner wall of the groove 11 is slidably connected with the punch seat 12.

[0028] Specifically, springs 13 are symmetrically fixedly connected to the bottom of the punch seat 12 near the left and right sides, and the bottom end of the spring 13 is fixedly connected to the bottom of the inner wall of the groove 11 to limit the position of the punch seat 12.

[0029] Specifically, the bottom of the base 1 is fixedly connected with a support seat 14 by bolts, and the bottom of the support seat 14 is fixed with an anti-skid pad 15 by glue. The anti-skid pad 15 is made of rubber material and plays an anti-skid role.

[0030] Specifically, a plurality of anti-skid grooves 151 are formed at the bottom of the anti-skid pad 15 . The anti-skid grooves 151 are evenly arranged at equal intervals to provide an anti-skid effect.

[0031] Furthermore, an n-shaped mounting frame 16 is fixedly connected to the top of the base 1 by bolts, and an electric telescopic rod 17 is fixedly connected to the top of the n-shaped mounting frame 16 by bolts to drive the mounting frame 18 to move.

[0032] Specifically, the telescopic end of the electric telescopic rod 17 passes through the bottom of the crossbeam of the n-shaped mounting frame 16 and is fixedly connected to the mounting frame 18 by bolts. The top of the mounting frame 18, near the rear side and near the left and right sides, is symmetrically fixedly connected to the hydraulic cylinder 19 by bolts to drive the moving frame 191 to move.

[0033] It should be added that the piston rod end of the hydraulic cylinder 19 passes through the bottom of the mounting frame 18 and is fixedly connected to the moving frame 191 by bolts, so as to drive the punch 192 to move, and the bottom of the moving frame 191 is fixedly connected to the punch 192 by bolts.

[0034] As a preferred embodiment of the present invention, an adjustment mechanism 2 is provided above the base 1 , and the adjustment mechanism 2 includes a rotary motor 21 , and the rotary motor 21 is fixedly connected to the top of the mounting frame 18 by bolts to drive the bidirectional threaded rod 22 to rotate.

[0035] Specifically, the output shaft of the rotary motor 21 is coaxially connected with a bidirectional threaded rod 22 for driving the slider 24 to move. The left end of the bidirectional threaded rod 22 is fixedly connected to a limiting block 23 by bolts for limiting the position of the slider 24 close to the left side.

[0036] Specifically, sliders 24 are symmetrically provided at the top of the mounting frame 18 near the front side and near the left and right sides. The sliders 24 are threadedly connected to the bidirectional threaded rod 22 to drive the top plate 25 to move.

[0037] Specifically, the top of the slider 24 is fixedly connected to the top plate 25 by bolts to drive the connecting plate 26 to move, and the bottom of the top plate 25 is fixedly connected to the connecting plate 26 by bolts to drive the placement plate 27 to move.

[0038] Specifically, the bottom of the connecting plate 26 is fixedly connected to the placing plate 27 by bolts to drive the clamping plate 28 to move, and the top of the placing plate 27 is fixedly connected to the clamping plate 28 by bolts to fix the metal plate.

[0039] During the specific use process, the user first turns on the rotating motor 21, and the rotating motor 21 drives the bidirectional threaded rod 22 to rotate, thereby driving the two sliders 24 to move away from the base 1, thereby driving the two top plates 25 to move away from the base 1, thereby driving the two connecting plates 26 to move away from the base 1, thereby driving the two placement plates 27 to move away from the base 1, thereby driving the two clamping plates 28 to move away from the base 1;

[0040] When the distance between the two clamping plates 28 reaches the specified distance, the rotating motor 21 is turned off, the metal plate is placed on the top of the two placement plates 27, and then the rotating motor 21 is turned on. The rotating motor 21 drives the bidirectional threaded rod 22 to rotate, thereby driving the two sliders 24 to move toward the base 1, thereby driving the two top plates 25 to move toward the base 1, thereby driving the two connecting plates 26 to move toward the base 1, thereby driving the two placement plates 27 to move toward the base 1, thereby driving the two clamping plates 28 to move toward the base 1;

[0041] Until the inner surfaces of the two clamping plates 28 are tightly fitted with the left and right ends of the metal plate respectively, the metal plate is fixed, and the telescopic end of the electric telescopic rod 17 is controlled to extend, thereby driving the mounting frame 18 to move downward, thereby driving the moving frame 191 to move downward, thereby driving the rotating motor 21 to move downward, thereby driving the bidirectional threaded rod 22 to move downward, thereby driving the two sliders 24 to move downward, thereby driving the two top plates 25 to move downward, thereby driving the two connecting plates 26 to move downward, thereby driving the two placing plates 27 to move downward, thereby driving the two clamping plates 28 to move downward, thereby driving the metal plate to move downward;

[0042] Until the bottom of the two placement plates 27 fits with the top of the base 1, the piston rods of the two hydraulic cylinders 19 are controlled to extend, thereby driving the movable frame 191 to move downward, thereby driving the punch 192 to move downward and punch the metal plate. After the stamping is completed, the telescopic end of the electric telescopic rod 17 is controlled to shorten, thereby driving the punch 192 to move upward. In this process, the two springs 13 push the punch seat 12 to eject the stamped electrons out of the groove 11.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
