Description
Technical Field
[0001] This utility model relates to the field of brake disc technology, specifically to a stamping die for processing motorcycle brake discs. Background Technology
[0002] Brake discs are the core component of braking systems in vehicles such as automobiles and motorcycles. Working in conjunction with brake calipers, they utilize friction to convert the vehicle's kinetic energy into heat energy, thereby achieving deceleration or stopping. The manufacturing of brake discs requires the use of stamping dies. These dies are primarily used to produce brake disc blanks or parts of their structure, pressing metal sheets into the preliminary shape of the brake disc using a press.
[0003] Currently, brake discs still have some shortcomings, such as the inconvenience of replacing stamping dies.
[0004] To overcome the problem of inconvenient replacement of stamping dies, a prior art Chinese patent (publication number: CN222470365U) discloses a stamping die for automotive brake discs. First, mounting blocks are inserted into the positioning slots to position the studs on both sides of the top of the moving die. Then, the tops of the studs are passed through the mounting holes, and fastening sleeves are fitted onto the outside of the studs and tightened. This achieves the purpose of securely installing the moving die at the bottom of the upper die base. The moving die can be disassembled by loosening and removing the fastening sleeves, thus achieving convenient and quick installation, fixation, disassembly, and replacement of the die.
[0005] However, the stamping dies currently in use still have certain shortcomings. The aforementioned document states that the moving die can be disassembled and replaced by inserting studs. However, when the die is processing steel materials, due to the hardness of the material, the die will vibrate during the stamping process, which can easily accelerate the wear of the die. Secondly, when the die collects waste, the waste can easily accumulate, affecting the waste collection effect. Therefore, the existing structure needs to be improved. Utility Model Content
[0006] The purpose of this utility model is to provide a stamping die for processing motorcycle brake discs, so as to solve the problems mentioned in the background art, such as large vibration during use of stamping dies, which affects service life, and insufficient efficiency of die for waste collection.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for processing motorcycle brake discs, comprising a base, a lifting rod connected to the upper surface of the base, and a stamping assembly connected to the top end of the lifting rod.
[0008] The base is equipped with a buffer mechanism to reduce the vibration intensity of the stamping die. The buffer mechanism includes a guide hole opened inside the base, a stamping plate connected inside the guide hole, guide blocks fixed on both sides of the stamping plate, the guide blocks sliding inside the guide groove, friction pads connected to the sides of the guide blocks, and the guide grooves symmetrically opened on the sides of the guide hole.
[0009] Furthermore, the buffer mechanism also includes symmetrically formed rotating grooves inside the base, and the rotating grooves are far away from the guide grooves.
[0010] Furthermore, a rotating shaft is installed inside the rotating groove, and a rotating shaft is also installed on the side of the stamping plate away from the guide block, with a damping spring installed between the two rotating shafts.
[0011] Furthermore, the base is provided with a swing mechanism to improve the collection effect of mold waste. The swing mechanism includes symmetrically opened rotating grooves at the bottom of the base. A guide plate is rotatably connected inside the rotating groove, and a fixing frame is fixed on the top of the guide plate.
[0012] Furthermore, an irregularly shaped block is rotatably connected to the interior of the rotating groove away from the guide plate via a bearing. A sliding rod is fixed to the bottom of the irregularly shaped block, and the sliding rod slides on the surface of the fixed frame. A ratchet is connected to the top of the irregularly shaped block, and a positioning block is attached to the side of the ratchet.
[0013] Furthermore, the positioning block is rotatably connected to the inside of the rotating groove by a torsion spring, and the guide block is fixed with an extrusion block on the side near the irregular block. The extrusion block slides through the rotating groove and inside the irregular block. A collection bucket is provided at the bottom of the base, and the collection bucket is located directly below the guide hole.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The motorcycle brake disc is processed using a stamping die. The damping spring can convert kinetic energy into heat energy through its own structure. The damping effect of the damping spring can reduce the vibration generated when the stamping disc squeezes the lifting rod. When the stamping disc vibration is reduced, the service life of the die and the stamping effect can be improved. After the guide plate angle is stabilized, the waste material after stamping can fall onto the surface of the guide plate through the guide hole, and then fall into the collection bucket for collection through the guide plate, which improves the waste material collection effect.
[0016] 2. A damping spring is provided, which can reduce the vibration generated by the stamping plate during the stamping of the brake plate, improve the stamping accuracy, and extend the service life of the mold.
[0017] 3. It is equipped with irregularly shaped blocks. By rotating the irregularly shaped blocks, the guide plate can be adjusted in angle, thereby guiding the waste material during feeding. This allows the waste material to be more evenly distributed inside the collection bin for collection, improving the efficiency of the mold in collecting waste material.
[0018] 4. Equipped with a ratchet and a positioning block, the irregular block can be positioned in one direction by the ratchet and the positioning block to prevent the irregular block from reversing after the guide plate is under pressure, thus improving the stability of the guide plate.

Detailed Implementation
[0028] 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.
[0029] Example 1, such as Figures 1-5 The present invention provides the following technical solution to address the problem of excessive vibration during the use of stamping dies, which affects their service life: a buffer mechanism is disclosed, comprising a base 1, a lifting rod 2 connected to the upper surface of the base 1, and a stamping assembly 3 connected to the top of the lifting rod 2.
[0030] The base 1 is equipped with a buffer mechanism to reduce the vibration intensity of the stamping die. The buffer mechanism includes a guide hole 105 opened inside the base 1. A stamping plate 101 is connected inside the guide hole 105. Guide blocks 102 are fixed on both sides of the stamping plate 101. The guide blocks 102 slide inside the guide groove 103. Friction pads are connected to the sides of the guide blocks 102. The guide grooves 103 are symmetrically opened on the sides of the guide hole 105. The buffer mechanism also includes a rotating groove 104 symmetrically opened inside the base 1. The rotating groove 104 is away from the guide groove 103. A rotating shaft is installed inside the rotating groove 104. A rotating shaft is also installed on the side of the stamping plate 101 away from the guide block 102. A damping spring 106 is installed between the two rotating shafts.
[0031] When using the stamping die, the brake disc material is placed on top of the base 1, and then the stamping assembly 3 is moved up and down by the lifting rod 2. The stamping assembly 3 can then stamp the brake disc through the processing head at the bottom. Since the brake disc is placed on top of the stamping disc 101, the brake disc will first squeeze the stamping disc 101 when it is being stamped. When the stamping disc 101 is squeezed, it can drive the guide block 102 to move downward. When the guide block 102 moves downward, the friction pad on the side can squeeze the side of the guide groove 103. After the friction pad is squeezed, The friction pad can deform and change the friction force. After the friction pad is deformed, the guide block 102 can slide through the guide groove 103. When the stamping plate 101 slides down, it can pull the damping spring 106 to extend through the rotating shaft. The damping spring 106 can convert kinetic energy into heat energy through its own structure. At the same time, the damping spring 106 can drive the rotating shafts at both ends to rotate. The damping effect of the damping spring 106 can reduce the rigid vibration intensity generated during the stamping of the brake disc material, and can also reduce the wear of the mold, improve the service life of the mold and the stamping effect.
[0032] Example 2, as follows Figure 2 , Figure 6 , Figure 7 and Figure 8The present invention provides the following technical solution to address the problem of insufficient waste collection efficiency of stamping dies: Based on Embodiment 1, a swing mechanism is disclosed: A swing mechanism to improve the waste collection effect of the die is provided inside the base 1. The swing mechanism includes symmetrically arranged rotating grooves 201 at the bottom of the base 1. A guide plate 202 is rotatably connected inside the rotating groove 201. A fixing frame 203 is fixed to the top of the guide plate 202. A shaped block 204 is rotatably connected to the interior of the rotating groove 201 away from the guide plate 202 via a bearing. A sliding rod 205 is fixed to the bottom of block 204. The sliding rod 205 slides on the surface of the fixed frame 203. A ratchet 206 is connected to the top of the irregular block 204. A positioning block 207 is attached to the side of the ratchet 206. The positioning block 207 is rotatably connected to the inside of the rotating groove 201 by a torsion spring. A pressing block 208 is fixed to the side of the guide block 102 near the irregular block 204. The pressing block 208 slides through the rotating groove 201 and the inside of the irregular block 204. A collection bucket 209 is provided at the bottom of the base 1, and the collection bucket 209 is located directly below the guide hole 105.
[0033] During mold operation, the stamping plate 101 is pressed downwards. As the stamping plate 101 moves downwards, the guide block 102 drives the extrusion block 208 to slide within the rotating groove 201 and the shaped block 204. When the extrusion block 208 slides to the inclined surface at the bottom of the shaped block 204, it can perform extrusion. When the lower inclined surface of the shaped block 204 is extruded, it can rotate within the rotating groove 201 via a bearing. When the damping spring 106 pushes the stamping plate 101 back to its original position through its own tension, the extrusion block 208 will extrude onto the upper inclined surface of the shaped block 204. 04 can continue to rotate. The two sides of the irregular block 204 rotate in the same direction. When the irregular block 204 rotates, it can drive the ratchet 206 to rotate. When the ratchet 206 rotates, the helical teeth can press against the side of the positioning block 207. After being pressed, the positioning block 207 can rotate inside the rotating groove 201, and the positioning block 207 can tighten the torsion spring. When the positioning block 207 is twisted to a certain position, the ratchet 206 can rotate inside the rotating groove 201. The rotation of the irregular block 204 can also drive the sliding rod 205 to rotate. When the moving rod 205 rotates, it can slide through the fixed frame 203, and the sliding rod 205 can press the fixed frame 203. When the fixed frame 203 is pressed, it can drive the guide plate 202 to rotate. The rotation of the guide plate 202 can adjust its angle inside the rotating groove 201. The guide plate 202 can swing its angle repeatedly through the rotation of the sliding rod 205. Since the pressing block 208 can only drive the irregular block 204 to rotate a little at a time, the guide plate 202 can only change its angle a little. The change in the angle of the guide plate 202 is simultaneous with the change in the fixed frame 201. Positioning block 207 will automatically reset by the torque of the torsion spring. When resetting, positioning block 207 can lock with ratchet 206 to prevent ratchet 206 from reversing after the guide plate 202 is under pressure, thus improving the stability of the angle adjustment of guide plate 202. After the angle of guide plate 202 is stable, the stamped waste can fall onto the surface of guide plate 202 through guide hole 105, and then fall into the collection bucket 209 for collection by the guide plate 202. The guided waste will not accumulate in one place, thus improving the efficiency of waste collection of stamping die.
[0034] Although the present invention 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 invention should be included within the protection scope of the present invention.
