Description

Technical Field

[0001] This utility model relates to the field of toothed belt processing technology, specifically a special mold for toothed belts. Background Technology

[0002] Toothed belts, also known as synchronous toothed belts, generally use fine steel wire rope as the reinforcing layer, covered with polyurethane or neoprene rubber. The center line of the reinforcing layer is defined as the pitch line of the belt. Its application is synchronous belt drive, which relies on the meshing of the teeth on the belt and the pulley. It is widely used in mechanical belt drives and has the characteristics of simple structure, smooth transmission, shock absorption, power transmission between large shafts and multiple shafts, low cost, no need for lubrication, and easy maintenance. In the production process of toothed belts, they often need to be extruded and formed by molds.

[0003] The application number "202223194500.2" discloses "a synchronous belt forming machine", which "includes a forming component. The forming component includes a support frame, a positioning roller, a connecting frame, a forming roller, a motor, and a threaded rod. The positioning roller is rotatably connected to the support frame, the connecting frame is slidably connected to the support frame, the forming roller is rotatably connected to the connecting frame, the motor is connected to the connecting frame, the forming roller is fixedly connected to the output end of the motor, the forming roller and the positioning roller are correspondingly arranged, the bottom end of the threaded rod is rotatably connected to the support frame, and the connecting frame is threadedly connected to the threaded rod." In this invention, the original synchronous belt is passed between the forming roller and the positioning roller. Then, the motor is turned on, and the motor drives the forming roller to rotate, which in turn presses and shapes the original synchronous belt. When it is necessary to adjust the gap between the forming roller and the positioning roller, the threaded rod can be rotated. The threaded rod will drive the connecting frame to move up and down, which in turn will drive the forming roller to move up and down, thereby adjusting the gap between the forming roller and the positioning roller. This allows for the pressing and shaping of original synchronous belts of different thicknesses, thus expanding the range of applications and making it highly practical.

[0004] However, the above method still has the following drawbacks: using a motor to drive the forming roller to rotate can achieve the pressing and forming of the synchronous belt, but the forming roller needs to be fixed on the connecting frame, which makes it inconvenient to remove the forming roller from the connecting frame and demold the formed synchronous belt, thus reducing the production efficiency of the synchronous belt.

[0024] Please see Figures 1-6A toothed belt mold includes a hanger 1 and a mold body 12. A hydraulic cylinder 2 is fixedly installed on the inner wall of one side of the hanger 1. The hydraulic rod of the hydraulic cylinder 2 is fixedly connected to a support 5. A support frame 8 is rotatably connected inside the support 5. An angle adjustment component 9 is provided on one side of the support 5 to adjust the support frame 8. The angle adjustment component 9 can adjust the angle of the mold body 12. By adjusting the mold body 12 from a horizontal state to a vertical state, it is convenient for the toothed belt to be demolded. A support shaft 11 is rotatably connected inside the support frame 8. The support shaft 11 can support the mold body 12. The support frame 8 increases the fulcrum of the support shaft 11 and improves its stability. One end of the mold body 12 is fixedly connected to one end of the support shaft 11. The other end of the mold body 12 is provided with a locking block 13. The other side of the hanger 1 is provided with a drive component 16 to drive the locking block 13 to rotate. The drive component 16 can drive the mold body 12 to rotate.

[0025] In this embodiment, preferably, the angle adjustment assembly 9 includes a motor 901 and a worm gear 902. The output shaft of the motor 901 is connected to the worm gear 902, and the worm gear 902 is meshed with a worm wheel 903. An adjustment shaft 904 is fixedly connected to the middle of the worm wheel 903. One end of the adjustment shaft 904 is fixedly connected to one side of the support frame 8. The worm gear 902 is rotatably connected to a stop frame 905. One side of the stop frame 905 and one side of the motor 901 are both fixedly connected to one side of the support 5. One end of the adjustment shaft 904 is rotatably connected to the inner wall of the other side of the stop frame 905. One side of the support 5 is rotatably connected to a retaining frame 905, which supports one end of the adjusting shaft 904 and the worm gear 902. The worm gear 902 is driven by a motor 901, and the worm gear 902 drives the adjusting shaft 904 to rotate through the worm wheel 903. This allows for adjustment of the tilt angle between the support frame 8 and the mold body 12. The other side of the support 5 is rotatably connected to an adjusting shaft 14, one end of which is fixedly connected to the other side of the support frame 8. The adjusting shaft 14 supports the other end of the support frame 8, ensuring the stability of the support frame 8 during adjustment.

[0026] In this embodiment, preferably, the drive assembly 16 includes a second motor 1601 and a second support shaft 1602. The second motor 1601 is fixedly connected to the other side of the hanger 1, and the second support shaft 1602 is rotatably connected to the inner wall of the other side of the hanger 1. The output shaft of the second motor 1601 is connected to one end of the second support shaft 1602, and the other end of the second support shaft 1602 is fixedly provided with a card seat 1603. The card block 13 is engaged with the card seat 1603. The card seat 1603 and the card block 13 can support and limit the other end of the mold body 12. The second motor 1601 drives the second support shaft 1602, and the card seat 1603 and the card block 13 can transmit torque, which can drive the mold body 12 to rotate.

[0027] In this embodiment, preferably, a plurality of guide sleeves 3 are fixedly provided on the inner wall of one side of the hanger 1. The guide sleeves 3 are slidably connected to guide posts 4. One end of the guide post 4 is fixedly connected to one side of the support 5. The guide post 4 and the guide sleeves 3 can improve the stability of the hydraulic cylinder 2, prevent the hydraulic cylinder 2 from bearing radial force, and ensure the service life of the hydraulic cylinder 2. The top of the support 5 is fixedly provided with a bracket 6. The middle of the top of the bracket 6 is fixedly provided with a support block 7. The inner wall of the top of the hanger 1 is fixedly provided with a hanging rail 10. The support block 7 is slidably connected to the hanging rail 10. The support block 7 and the hanging rail 10 can support and guide the support 5, ensure the horizontal movement of the support 5, and prevent it from tilting and deviating. The support 5 and the support frame 8 are both made of stainless steel. The inner walls of both sides of the support frame 8 are welded with counterweights 15. The counterweights 15 can balance the side of the support frame 8 away from the mold body 12, and ensure the balance of the support frame 8.

[0028] In use, the operator drives the support shaft 1602 via the motor 1601 of the drive assembly 16. The clamping seat 1603 and the clamping block 13 can transmit torque, which can drive the mold body 12 to rotate. The toothed belt can be pressed and formed by the mold body 12. When it is necessary to demold the formed toothed belt, the operator first pulls the support 5 via the hydraulic cylinder 2 to separate the clamping block 13 from the clamping seat 1603, so that the mold body 12 is away from the drive assembly 16. Then, the operator drives the worm 902 via the motor 901 of the angle adjustment assembly 9. The worm 902 drives the adjustment shaft 904 to rotate via the worm wheel 903. This allows the tilt angle of the support frame 8 and the mold body 12 to be adjusted. By adjusting the mold body 12 from a horizontal state to a vertical state, the toothed belt can be demolded vertically by the demolding machine. The counterweight 15 can provide counterweight to the side of the support frame 8 away from the mold body 12, which can ensure the balance of the support frame 8.

[0029] After the angle of the mold body 12 is adjusted, the worm 902 can achieve self-locking of the adjustment shaft 14 through the angular friction between it and the worm wheel 903, ensuring the stability of the angle of the support frame 8. After the toothed belt is demolded, the operator reverses the operation, first adjusting the mold body 12 to a horizontal state, and then driving it to reset through the hydraulic cylinder 2, pushing the locking block 13 into the locking seat 1603, thus completing the quick installation of the mold body 12. During the movement of the support 5, the support block 7 and the hanging rail 10 can support and guide the support 5, ensuring the horizontal movement of the support 5, while preventing it from tilting and shifting. The guide post 4 and the guide sleeve 3 can improve the stability of the hydraulic cylinder 2, prevent the hydraulic cylinder 2 from bearing radial force, and ensure the service life of the hydraulic cylinder 2.
