Description

A forming device for machining motorcycle brake discs Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a forming device for processing and forming motorcycle brake discs. Background Technology

[0002] The motorcycle brake disc is a key component of the motorcycle braking system, primarily used to achieve the vehicle's deceleration and stopping functions. Its working principle is based on friction braking. When the rider operates the brake lever or presses the brake pedal, the piston inside the brake caliper pushes the brake pads tightly against the brake disc. At this time, a strong frictional force is generated between the brake pads and the brake disc, thereby converting the motorcycle's kinetic energy into heat energy, causing the motorcycle to gradually decrease in speed until it stops.

[0003] Motorcycle brake discs are often formed by stamping to ensure that the sheet metal deforms evenly during the stamping process, achieving accurate shape and dimensions. The die typically consists of an upper die and a lower die; traditional stamping equipment is inconvenient to remove from the die after stamping, making material unloading difficult and overall operation inconvenient. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a forming device for processing and molding motorcycle brake discs.

[0006] (II) Technical Solution

[0008] A stamping assembly, comprising a bracket, a top plate, a lifter, a lifting plate, and an upper die, wherein brackets fixed to the stamping table are provided at the four corners below the top plate, the output end of the lifter passes through the top plate and is connected to the lifting plate, and the upper die is provided below the lifting plate;

[0009] The supporting assembly includes a lower die, a rotating shaft, a gear, a mounting base, a mold-lifting frame, a connector, and a rack. A stamping table is provided with a stamping groove with an upper opening. A lower die, adapted to the upper die, is provided on the bottom wall of the stamping groove. The stamping groove is I-shaped. Two sets of rotating shafts are rotatably mounted on the left and right sides of the stamping table. The front and rear ends of the rotating shafts extend into the stamping groove and are connected to the center of the gear. A rack meshing with the gear is provided below the lifting plate. A mounting base extending into the stamping groove is provided in the middle part of the rotating shaft. The mold-lifting frame is connected to the mounting base via a connector. A notch adapted to the mold-lifting frame is provided on the stamping table. An arc-shaped groove adapted to the end of the mold-lifting frame is provided on the lower die.

[0010] To facilitate the positioning of the mold-lifting frame, this utility model is improved by including an elastic element and a locking block as the connecting member. The mounting base is provided with movable grooves on both sides near the rotating shaft. The two ends of the elastic element are respectively connected to the inner wall of the movable groove and the locking block. The mold-lifting frame is also provided with unlocking holes on both sides that are adapted to the locking block.

[0011] Preferably, the elastic element includes a spring and a telescopic rod, the spring is sleeved on the telescopic rod, and both ends of the spring and the telescopic rod are respectively connected to the movable groove and the locking block.

[0012] To ensure the stability of the lifting platform's movement, this utility model is improved by providing a guide rod that penetrates the top plate on the lifting platform, with the guide rod arranged in several evenly distributed groups.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a forming device for processing and molding motorcycle brake discs, which has the following beneficial effects:

[0017] This forming device for machining motorcycle brake discs features a load-bearing component design that facilitates the mold-lifting process. After stamping, as the lifting plate rises, the rack drives the gear to rotate, which in turn rotates the shaft. The mounting base rotates accordingly, and through the connecting parts, it lifts the mold-lifting frame, bringing the formed brake disc out of the lower mold.

[0018] The connector employs a design with elastic elements and locking blocks. The elastic elements include a spring and a telescopic rod, while the locking blocks are adapted to the unlocking holes of the mold-raising frame. When installing the mold-raising frame, the locking blocks engage with the unlocking holes under the action of the elastic elements, achieving precise positioning of the mold-raising frame and preventing displacement of the mold-raising frame during stamping, thus ensuring the accuracy and quality of the brake disc stamping.

[0025] 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.

[0026] Please refer to Figures 1-5. A forming apparatus for machining motorcycle brake discs includes a stamping table 1, and further includes:

[0027] A stamping assembly, comprising a bracket 2, a top plate 3, a lifter 4, a lifting plate 5, and an upper die 6. The top plate 3 has brackets 2 fixed to the stamping table 1 at its four lower corners. The output end of the lifter 4 passes through the top plate 3 and is connected to the lifting plate 5. The upper die 6 is located below the lifting plate 5.

[0028] During the stamping of motorcycle brake discs, the lifting device 4 is activated. The lifting device 4 uses a hydraulic cylinder, and its output end pushes the lifting plate 5 downward. Since the lifting plate 5 is equipped with an upper die 6, as the lifting plate 5 descends, the upper die 6 gradually approaches the lower die 7 on the bottom wall of the stamping groove on the stamping table 1. During this process, the metal sheet placed between the upper and lower dies 7 is subjected to the pressure of the upper die 6 and gradually undergoes plastic deformation under the constraint of the stamping groove. The guide rods 16, evenly arranged on the lifting plate 5 and penetrating the top plate 3, ensure the stability of the lifting plate 5 during the lifting process, allowing the upper die 6 to accurately cooperate with the lower die 7, ensuring uniform deformation of the sheet metal, thereby stamping out a brake disc that meets the shape and size requirements.

[0029] The supporting assembly includes a lower die 7, a rotating shaft 8, a gear 9, a mounting base 10, a mold-lifting frame 11, a connecting piece, and a rack 12. The stamping table 1 is provided with a stamping groove with an upper opening. The bottom wall of the stamping groove is provided with a lower die 7 that is adapted to the upper die 6. The stamping groove is in the shape of an "I". Two sets of rotating shafts 8 are rotatably provided on the left and right sides of the stamping table 1. The front and rear ends of the rotating shafts 8 extend into the stamping groove and are connected to the center of the gear 9. A rack 12 that meshes with the gear 9 is provided below the lifting plate 5. The middle part of the rotating shaft 8 is provided with a mounting base 10 that extends into the stamping groove. The mold-lifting frame 11 is connected to the mounting base 10 through a connecting piece. The stamping table 1 is also provided with a notch that is adapted to the mold-lifting frame 11. The lower die 7 is also provided with an arc-shaped groove that is adapted to the end of the mold-lifting frame 11.

[0030] After stamping, the lifting device 4 drives the lifting plate 5 to rise. The rack 12 below the lifting plate 5 rises with the lifting plate 5. Because the rack 12 meshes with the gear 9, the rise of the rack 12 drives the gear 9 to rotate. The gear 9 is mounted on the rotating shaft 8, and the rotation of the gear 9 causes the rotating shaft 8 to rotate as well. The middle part of the rotating shaft 8 is provided with a mounting seat 10. The mounting seat 10 rotates with the rotating shaft 8. The mounting seat 10 is connected to the mold-lifting frame 11 through a connector, so when the mounting seat 10 rotates, it will drive the mold-lifting frame 11 to move. The end of the mold-lifting frame 11 is adapted to the arc groove on the lower mold part 7. The stamping table 1 is also provided with a notch adapted to the mold-lifting frame 11. When the mounting seat 10 rotates, the mold-lifting frame 11 will rise along the arc groove, bringing out the formed brake disc from the stamping groove, completing the mold-lifting action.

[0031] It should be noted that when the mold is lifted, the lifting device 4 is fully retracted and the lifting plate 5 is at its highest position. When loading, the lifting device 4 is in a partially extended state. At this time, the end of the mold lifting frame 11 is lower than the arc groove. During the stamping operation, the rotating shaft 8 drives the mold lifting frame 11 to move away from the stamping groove through the mounting base 10.

[0032] In actual use, the upper mold 6 is connected to the lifting plate 5 by bolts, and the lower mold 7 is connected to the stamping table 1 by bolts. It can be replaced as needed. At this time, it is necessary to replace the mold release frame 11 of the corresponding specification. For this purpose, the connecting parts include elastic elements and locking blocks 13. The mounting base 10 is provided with movable grooves on both sides near the rotating shaft 8. The two ends of the elastic element are respectively connected to the inner wall of the movable groove and the locking block 13. The mold release frame 11 is also provided with unlocking holes on both sides that are adapted to the locking blocks 13. The elastic element includes a spring 14 and a telescopic rod 15. The spring 14 is sleeved on the telescopic rod 15. The two ends of the spring 14 and the telescopic rod 15 are respectively connected to the movable groove and the locking block 13. The mounting base 10 rotates with the rotating shaft 8. The mounting base 10 is connected to the mold-lifting frame 11 via a connector. The telescopic rod 15, fitted with a spring 14, stably supports the locking block 13. The locking block 13 is locked in the unlocking holes on both sides of the mold-lifting frame 11. Therefore, when the mounting base 10 rotates, it will drive the mold-lifting frame 11 to move. It should be noted that the connector can stably assemble the mounting base 10 with the mold-lifting frame 11. As needed, the mold-lifting frame 11 can be further connected to the mounting base 10 via bolts to prevent the mold-lifting frame 11 from disengaging from the mounting base 10 due to vibration. The connector serves as a pre-positioning element.

[0033] The lifting plate 5 is also provided with a guide rod 16 that passes through the top plate 3, and the guide rod 16 is arranged in several groups evenly.

[0034] The four corners of the stamping table 1 are provided with support legs 17, which stably support the stamping table 1.

[0035] During the entire stamping and die-setting process, some waste material is generated. A waste collection box 18 with an opening at the top is provided below the stamping table 1, and the waste material falls into the waste collection box 18 from the opening of the stamping table 1. Casters 19 are provided at the four corners of the waste collection box 18 for easy movement. When it is necessary to fix the waste collection box 18, the brakes 20 on the sides of the casters 19 can be used for fixation, facilitating the centralized collection and cleaning of waste material.
