[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0017] Please see Figures 1-5 The present invention provides the following technical solution: A punching device for processing motorcycle gears, comprising: Stamping base 1; The material collection hole 15 is located at the upper end of the stamping base 1; The stamping assembly includes a lower pressing groove 2, a lower pressing sliding groove 3, a lower pressing sliding plate 4, a spring groove 5, a discharge spring 6, a discharge ejection block 7, a stamping fixing tooth 8, a gear fixing guide chamfer 9, and a stamping discharge hole 10. The lower pressing groove 2 is opened on the upper inner wall of the discharge collection hole 15, the lower pressing sliding groove 3 is opened on the lower inner wall of the lower pressing groove 2, the lower pressing sliding plate 4 is slidably connected in the lower pressing sliding groove 3, the spring groove 5 is opened on the lower inner wall of the lower pressing sliding groove 3, the discharge spring 6 is fixedly connected to the lower end of the lower pressing sliding plate 4, the discharge ejection block 7 is fixedly connected to the upper end of the lower pressing sliding plate 4 and slides in the lower pressing groove 2, the stamping fixing tooth 8 is opened on the circumferential inner wall of the lower pressing groove 2, the gear fixing guide chamfer 9 is opened on the upper end of the stamping fixing tooth 8 and is inclined, and the stamping discharge hole 10 is opened on the upper end of the discharge ejection block 7.

[0018] In a specific embodiment of this utility model, the gear to be processed is first pushed horizontally above the stamping base 1 by manual or mechanical feeding from both sides. The inner hole of the gear is aligned with the stamping fixing tooth 8. During the pushing process, the edge of the gear contacts the gear fixing guide chamfer 9. The inclined chamfer plays a guiding role, allowing the gear to smoothly fit into the stamping fixing tooth 8 and complete axial positioning, ensuring that the gear is concentrically aligned with the stamping discharge hole 10 at the upper end of the ejector block 7. Subsequently, the upper stamping machine 12 drives the stamping head downward. The stamping head passes through the stamping discharge hole 10 to perform a punching operation on the gear. At this time, the ejector block 7 is lowered as a whole under the stamping force. The downward movement of the sliding plate 4 compresses the discharge spring 6 and moves it downward along the sliding groove 3. At the same time, the waste or debris generated during punching falls into the lower part of the stamping base 1 through the discharge collection hole 15 for centralized collection. After punching is completed, the punching head moves upward to reset. After the external force disappears, the discharge spring 6 releases its elastic potential energy, pushing the sliding plate 4 to drive the discharge push block 7 to slide upward to reset. The discharge push block 7 pushes the punched gear out from the stamping fixed tooth 8, realizing automatic demolding and material discharge. This makes it easy for operators to pick up the parts or move to the next process. The whole process is simple to operate, accurate in positioning, and smooth in material discharge, which improves punching efficiency and operational safety.

[0019] Please refer to the details. Figures 1-5 The outer circumferential surface of the ejector block 7 is provided with overlapping teeth 14, which mesh with the stamping fixing teeth 8.

[0020] In this embodiment, the overlapping teeth 14 on the outer surface of the ejector block 7 mesh with the stamping fixing teeth 8 to form a stable meshing structure, preventing the ejector block 7 from deflecting or getting stuck during the reset process.

[0021] Please refer to the details. Figures 1-5 The lower inner wall of the sliding groove 3 is provided with a material collection hole 15.

[0022] In this embodiment, the waste and metal shavings generated during the stamping process fall into the lower inner wall of the lower sliding groove 3 through the stamping discharge hole 10 and the lower pressing groove 2 under the action of gravity or impact, and are discharged to the collection area below the stamping base 1 through the discharge collection hole 15, thereby realizing automatic waste cleaning.

[0023] Please refer to the details. Figures 1-5 The upper end of the stamping base 1 is provided with a lifting limit rod 11, and the side end of the lifting limit rod 11 is slidably connected to a stamping plate 16, and a stamping machine 12 is provided inside the stamping plate 16.

[0024] In this embodiment: the overlapping teeth 14 on the outer surface of the ejector block 7 are engaged with the stamping fixing teeth 8; then the stamping machine 12 installed inside the stamping plate 16 is started, the stamping machine 12 drives the stamping head downward, and the stamping plate 16 slides along the side of the lifting limit rod 11 set at the upper end of the stamping base 1. The lifting limit rod 11 guides and limits the movement direction of the stamping plate 16 to ensure that the stamping process is stable and vertical and to prevent deviation; the stamping head passes through the stamping discharge hole 10 to punch the gear. Under the action of the stamping force, the ejector block 7 moves downward as a whole, driving the lower sliding plate 4 to compress the ejector spring 6 and move downward along the lower sliding groove 3. During the stamping process, the waste and metal shavings generated fall into the lower inner wall of the lower sliding groove 3 through the stamping discharge hole 10 and the lower pressing groove 2 under the action of gravity or impact, and are discharged to the collection area below the stamping base 1 through the discharge collection hole 15, realizing automatic waste cleaning. After the punching is completed, the stamping machine 12 returns, the stamping head moves upward to reset, the discharge spring 6 releases elastic potential energy, pushes the lower pressing sliding plate 4 to drive the discharge ejection block 7 to slide upward to reset, and the overlapping tooth 14 rises smoothly under the meshing guidance of the stamping fixed tooth 8 to prevent deviation or jamming. Finally, the processed gear is vertically ejected from the stamping fixed tooth 8 to realize automatic demolding.

[0025] Please refer to the details. Figures 1-5 Two infeed and discharge slide plates 13 are provided on both sides of the stamping base 1.

[0026] In this embodiment: the feed and discharge slide plate 13 provides a smooth sliding guide for the gear, which facilitates quick loading by manual or robotic arms. Finally, the processed gear is vertically ejected from the stamping fixed gear 8. After being ejected, the gear slides out again through the feed and discharge slide plates 13 on both sides, which facilitates quick material removal by manual or automated equipment and entry into the next process. The entire workflow achieves continuous and efficient loading and unloading operations with the help of the feed and discharge slide plate 13. Combined with the stable stamping action guided by the lifting limit rod 11, it ensures accurate positioning, smooth material discharge, and automatic waste collection, which significantly improves the production efficiency of punching operations and the reliability of equipment operation.

[0027] Please refer to the details. Figures 1-5The output end of the stamping machine 12 is provided with a stamping port 17, which is matched with the stamping blanking hole 10.

[0028] In this embodiment: the precise matching of the stamping port 17 and the stamping blanking hole 10 in the entire process ensures the punching accuracy and stability. The feeding and unloading slide plate 13 enables continuous and efficient loading and unloading. The lifting limit rod 11 ensures stable stamping and automatic waste collection, which significantly improves the automation level, processing accuracy and production efficiency of the punching operation.

[0029] The working principle and usage process of this utility model are as follows: During operation, the motorcycle gear to be processed is horizontally pushed into the center position of the device through the infeed and discharge slide plates 13 opened on both sides of the stamping base 1. The infeed and discharge slide plates 13 provide smooth sliding guidance, facilitating quick loading by manual or robotic arms. During the pushing process, the inner hole of the gear is aligned with the stamping fixed tooth 8, and the edge contacts the gear fixed guide chamfer 9. The inclined chamfer plays a guiding and positioning role, allowing the gear to smoothly fit into the stamping fixed tooth 8 and achieve precise axial positioning, ensuring that the gear is concentrically aligned with the stamping discharge hole 10 at the upper end of the discharge ejection block 7. At the same time, the overlapping teeth 14 on the outer surface of the discharge ejection block 7 maintain a meshing state with the stamping fixed tooth 8, ensuring smooth subsequent movement. Then, the stamping machine 12 inside the stamping plate 16 is started, and the stamping port 17 at its output end moves downward and precisely matches and aligns with the stamping discharge hole 10. Under the guidance of the lifting limit rod 11, the stamping plate 16 moves along the stamping base. The seat 1 moves vertically downwards to ensure that the stamping process is stable and does not deviate. The stamping port 17 passes through the stamping discharge hole 10 to punch the gear. The stamping force causes the discharge push block 7 to move downwards as a whole, which drives the lower sliding plate 4 to compress the discharge spring 6 and move downwards along the lower sliding groove 3. The waste and debris generated during processing fall into the bottom of the lower sliding groove 3 through the stamping discharge hole 10 and the lower groove 2 under the action of gravity or impact, and are discharged to the bottom of the device for centralized collection through the discharge collection hole 15 opened on its lower inner wall. After the punching is completed, the stamping machine 12 returns, the stamping port 17 moves upwards and exits, the discharge spring 6 releases elastic potential energy, pushes the lower sliding plate 4 to drive the discharge push block 7 to reset upwards, and the overlapping gear 14 is ensured to rise vertically and smoothly under the meshing constraint of the stamping fixed gear 8 to avoid deflection or jamming. Finally, the processed gear is pushed out from the stamping fixed gear 8. After being pushed out, the gear slides out again through the feeding and discharging slide plate 13, which is convenient for picking up materials or entering the next process. The entire workflow achieves automatic positioning, stable stamping, automatic material discharge, and waste collection, significantly improving processing efficiency, accuracy, and equipment reliability.
