[0022] 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.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a cutting device for bicycle hub parts, comprising a base 1, mounting grooves 2 on both the front and rear sides of the left end of the base 1, a gantry 3 on the upper left end of the base 1, a fixing block 4 fixedly connected to the lower end of the gantry 3, the end of the fixing block 4 fixedly connected to the inside of the mounting groove 2, a first hydraulic rod 5 fixedly connected to the top of the gantry 3, a lifting plate 6 fixedly connected to the driving end of the first hydraulic rod 5, a first limiting rod 10 passing through both the front and rear ends of the lifting plate 6, the upper and lower ends of the first limiting rod 10 fixedly connected to the inside of the gantry 3, a side plate 7 fixedly connected to the lower side of the lifting plate 6, a cutting wheel 8 rotatably connected to the inner side of the side plate 7, a drive motor 9 fixedly connected to the left side of the side plate 7, the driving end of the drive motor 9 fixedly connected to the middle of the cutting wheel 8, a cutting opening 11 for cooperating with the cutting wheel 8 opened in the middle of the left end of the base 1, and a discharge guide plate 12 fixedly connected to the left end of the base 1.

[0024] The raw material is placed horizontally along the length of the base 1, with its left end extending to the vicinity of the cutting opening 11. The drive motor 9 is started, driving the cutting wheel 8 to rotate at high speed until it reaches the preset speed. The first hydraulic rod 5 starts to move, with its drive end extending downward to push the lifting plate 6 to descend smoothly along the guide of the first limit rod 10. The lifting plate 6 drives the side plate 7 and the cutting wheel 8 to move downward as a whole. The high-speed rotating cutting wheel 8 contacts the metal raw material through the cutting opening 11 to complete the cutting operation. The first limit rod 10 ensures the vertical movement accuracy of the tool during the cutting process. After the cutting is completed, the first hydraulic rod 5 retracts, driving the cutting wheel 8 to rise and reset.

[0025] Reference Figure 1 , Figure 2 and Figure 4 A movable groove 13 is provided on the lower side of the base 1. A lead screw 14 is rotatably connected inside the movable groove 13. A mounting plate 15 is fixedly connected to the right end of the base 1. The right end of the lead screw 14 is rotatably connected inside the mounting plate 15. A threaded block 17 is threadedly connected to the outside of the lead screw 14. A push plate 18 is fixedly connected to the top of the threaded block 17. A motor 16 is fixedly connected to the right side of the mounting plate 15. The drive end of the motor 16 is fixedly connected to the right end of the lead screw 14. A feeding plate 19 for placing raw materials is fixedly connected to the rear side of the base 1. A U-shaped plate 20 is fixedly connected to the top of the gantry frame 3. A second limiter is fixedly connected to the inner side of the U-shaped plate 20. The second limiting rod 21 has a lifting block 22 that slides up and down on its outside. The upper end of the second limiting rod 21 has a spring 23. The front side of the lifting block 22 is fixedly connected to a baffle 24 for blocking the raw material. The upper left side of the mounting plate 15 is fixedly connected to a connecting plate 26. The left end of the connecting plate 26 is fixedly connected to a first pad 25. The lower end of the first pad 25 is fixedly connected to the upper side of the base 1. The upper sides of the first pad 25 and the connecting plate 26 are jointly fixedly connected to a second pad 27. The middle part of the second pad 27 is fixedly connected to a second hydraulic rod 28. The lower end of the second hydraulic rod 28 is fixedly connected to a pressure plate.

[0026] After one cut is completed, the first hydraulic rod 5 drives the lifting plate 6 to rise, which in turn moves the cutting wheel 8 and the side plate 7 upward. When the lifting plate 6 rises, it pushes the lifting block 22 upward through mechanical linkage or contact, compressing the spring 23 and temporarily releasing the baffle 24 from obstructing the raw material. The raw material to be cut slides into the groove of the base 1 along the inclined surface of the feeding plate 19 under the action of gravity. The motor 16 starts and drives the lead screw 14 to rotate, which drives the threaded block 17 and the push plate 18 to move to the left, pushing the raw material toward the cutting opening 11. When the raw material reaches the set position, the second hydraulic rod 28 drives the pressure plate to press down, fixing the position of the raw material and preventing it from shifting during cutting, so that subsequent cutting can be carried out.

[0027] Working principle: The raw material is conveyed to the inclined surface of the feeding plate 19 by the conveying mechanism. The baffle 24 blocks the raw material. After the cutting wheel 8 completes one cut, the first hydraulic rod 5 drives the cutting wheel 8 to move upward through the lifting plate 6. The upward movement of the lifting plate 6 drives the baffle 24 to move upward, thereby driving the lifting block 22 to move upward and compressing the spring 23. As the baffle 24 moves upward, the obstruction of the raw material is removed, and the raw material falls into the groove of the base 1 through the inclined surface of the feeding plate 19. Subsequently, the first hydraulic rod 5 immediately drives the lifting plate 6 to descend a certain distance, thereby causing the spring 23 to push the lifting block 22 and the baffle 24 to move upward. Plate 24 descends, thus blocking subsequent raw materials. The motor 16, which is set to start, drives the lead screw 14 to rotate. The rotating lead screw 14 drives the threaded block 17 and the push plate 18 to move to the left, thereby pushing the raw materials to the left. The second hydraulic rod 28, which is set to start, drives the pressure plate to move downward, fixing the raw materials. The first hydraulic rod 5, which is set to start, drives the lifting plate 6 to descend, thereby driving the cutting wheel 8 and the drive motor 9 to move downward. The cutting wheel 8 cuts the raw materials. Then the push plate 18 continues to push the raw materials to the left for the next cut, and pushes the cut raw materials to the left to fall onto the unloading guide plate 12 for unloading.

[0028] 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.
