The inside of the shell 1 is fixedly connected with a stamping drive assembly that provides stamping power. The stamping drive assembly provides power to drive the stamping. The right side of the stamping drive assembly is fixedly connected with a connecting shaft 6. The connecting shaft 6 is an important transmission shaft 3. The connecting shaft 6 connects the drive motor 2 and the transmission system. The connecting shaft 6 transmits power from the drive motor 2 to the transmission assembly, and the transmission assembly drives the upper mold 12 to perform stamping. The right side of the connecting shaft 6 is fixedly connected with a transmission assembly. The transmission assembly is one of the core components of the entire stamping device. It is responsible for transferring the stamping power from the drive motor 2 to the transmission assembly. The moving assembly is transmitted to the sliding block 11 and the upper mold 12.

It works together with the lower mold to stamp the motor stator punching. A mold groove is provided at the bottom of the upper mold 12 for closely fitting with the sliding block 11 to ensure that the shape and size of the punching are accurate. The interior of the shell 1 is slidably connected to a waste collection mechanism for guiding the waste generated during the stamping process into the waste collection box 26 to prevent the waste from scattering. The left side of the upper mold 12 is detachably connected to a finished product automatic unloading mechanism.

[0026] The stamping drive assembly includes a drive motor 2, which can provide high-speed power and transmit the power to the upper mold 12 and the lower mold through the transmission mechanism. The drive motor 2 is fixedly connected to the inside of the shell 1. The left side of the drive motor 2 is fixedly connected to the transmission shaft 3, which serves as an intermediate transmission member for the power provided by the drive motor 2. The rotational force is transmitted to the working shaft 4 through the cooperation of the belt 5. The outside of the connecting shaft 6 is fixedly connected to the working shaft 4, which serves as the last transmission member of the stamping drive assembly and transmits the driving force to the connecting shaft 6. The working shaft 4 is externally coupled to the transmission shaft 3. The belt 5, as the transmission intermediate piece of the rotational force, cooperates with the working shaft 4 and the transmission shaft 3 to complete the transmission of the driving power. The transmission assembly includes two deflection blocks 8. Through the design of the eccentric block, the deflection block 8 drives the connecting shaft 3 9 to perform linear motion when it is driven to rotate by the connecting block 1.

[0027] The automatic unloading mechanism for finished products includes two fixed blocks 17, which connect the automatic unloading mechanism for finished products with the upper mold 12, so that the automatic unloading mechanism for finished products can move with the upper mold 12, and the two fixed blocks 17 are detachably connected to both sides of the upper mold 12, and the two fixed blocks 17 are rotatably connected to the support shaft 18 on the far side, which serves as a connecting piece and also transmits the force generated during the movement. Specifically, the support shaft 18 transmits the force to the connecting shaft four 19, thereby driving the movement of the unloading block 24, and the far side of the support shaft 18 is rotatably connected to the connecting shaft four 19, and the support shaft 18 is connected to the adjusting shaft 22, so that the adjusting shaft 22 can be adjusted when the support shaft 18 moves. The internal rotation of the connecting shaft four 19 is connected to the adjusting shaft 22, which is connected to the unloading block 24. When the adjusting shaft 22 moves, the unloading block 24 can follow the adjustment The section shaft 22 moves, thereby completing the guided blanking of the motor stator punching sheet. The external rotation of the adjusting shaft 22 is connected to the extension block 20. The extension block 20 extends the distance between the two adjusting shafts 22, so that the adjusting shaft 22 can provide more stable support for the blanking block 24. The interior of the extension block 20 is fixedly connected to the support block 21, which serves as the core support and stabilization part of the automatic blanking mechanism of the finished product, providing stability for the blanking block 24 during the guidance process of the finished product. The blanking block 24 is detachably connected to one side of the adjusting shaft 22 to guide the finished product. The top of the blanking block 24 is detachably connected to the stabilizing block 23 to ensure the stability of the blanking block 24 during the blanking process of the finished product. A slide groove is provided inside the blanking block 24, and the top of the right side of the blanking block 24 is cut. The stabilizing block 23 is a work-shaped block, and the two sides of the stabilizing block 23 are detachably connected to the two sides of the blanking block 24.

[0028] Reference Figure 4 The waste collection mechanism includes a waste guide block three 25, which guides the stamped waste so that it can enter the waste collection box 26. The waste guide block three 25 is fixedly connected to the inside of the shell 1, and the inside of the shell 1 is slidably connected with the waste collection box 26. The sliding connection enables the waste collection box to be disassembled after collecting a certain amount of waste, thereby improving the utilization rate of the material. The waste collection box 26 is slidably connected to the bottom of the waste guide block three 25, and the left side of the feed chute is fixedly connected to the limit block 15. The limit block 15 provides a method of avoiding the waste of new materials due to exceeding the placement range during the process of putting in new materials. The two sides of the shell 1 are fixedly connected with guide blocks two 16 to guide the route of the new material during the placement process, avoiding the waste of new materials caused by the stability of the angle. The guide block two 16 on the left side is connected to the limit block 15.

[0029] Working principle: First, the drive motor 2 starts and provides high-speed power. The drive motor 2 transmits the rotational force to the work shaft 4 through the transmission shaft 3 and the belt 5. The work shaft 4 then transmits the power to the connecting shaft 1 6 through the belt 5, driving the core part of the transmission assembly - the deflection block 8. The deflection block 8 drives the connecting shaft 3 9 to perform linear motion, and then pushes the sliding block 11 to slide up and down, driving the upper mold 12 to complete the stamping work. During this process, the guide block 10 limits the sliding angle and sliding range of the sliding block 11 to avoid damage to the stamping device.

[0030] During the stamping process, the motor stator punching sheet is placed between the lower die block 14 and the upper die 12. When the upper die 12 is pressed down, the punching sheet is accurately stamped and formed. The waste material after stamping is guided to the waste collection box 26 through the waste guide block 3 25 to prevent the waste material from scattering. In addition, the feed chute and the limit block 15 inside the housing 1 ensure the correct placement of the new material to avoid the waste of the material due to exceeding the predetermined range. The guide block 2 16 guides the new material to avoid the waste of the new material due to the angle of the new material.

[0031] The connection between the upper mold 12 and the automatic unloading mechanism of the finished product is completed through the fixed block 17. When the upper mold 12 completes the stamping action, the automatic unloading mechanism of the finished product starts to work. The support shaft 18 drives the movement of the connecting shaft 4 19, the adjusting shaft 22 and the unloading block 24 to ensure that the stamped stator punching is smoothly taken out of the mold and moved to the collection area. In order to ensure that the unloading block 24 stably guides the unloading of the finished product, the stabilizing block 23 ensures the stability of the unloading process. After the unloading process is completed, the stamping device is ready for the next cycle.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
