Description

Technical Field

[0001] The utility model relates to a blanking device, in particular to a blanking device for a cutting disc press. Background Art

[0002] In the production of cutting discs, first, raw materials are evenly mixed by a mixing device. The raw materials are generally a mixture of diamond particles and metal powder with a binder resin added. The mixed raw materials are put into a blanking device. Below the blanking port of the blanking device, there is a die conveyor belt 10. A number of dies 23 are evenly installed on the die conveyor belt 10. The operation of the die conveyor belt 10 drives the dies 23 to move below the blanking device. When one of the dies 23 runs below the blanking port of the blanking device, the die conveyor belt 10 stops. At this time, a fixed amount of raw materials fall downward through the blanking port of the blanking device into the lower die 23, achieving the purpose of feeding the die 23.

[0003] The quantitative feeding of the existing blanking device is achieved by pre-storing a set amount of raw materials in the feeding port. Since the pre-storage space in the feeding port is fixed, the quantitative blanking of the blanking device is fixed. When changing the die to produce cutting discs of different specifications and models, the entire blanking device needs to be replaced, resulting in too long production standby time, wasting time, and thus reducing the production efficiency of the cutting discs.

[0028] The present utility model will be described in detail below with reference to the drawings and embodiments:

[0029] Please refer to Figures 1-9, the blanking device of the cutting disc press of the present utility model includes a blanking cylinder 1. A rotating shaft 2 is coaxially arranged on the inner bottom wall of the blanking cylinder 1. A sweeping rod 3 is fixedly arranged on the upper part of the outer surface of the rotating shaft 2. A baffle 4 is fixedly arranged on the lower end surface of the sweeping rod 3. A blanking hole 5 is radially opened on the inner bottom wall of the blanking cylinder 1 near the side wall. A quantitative block 6 is fixedly arranged on the lower end surface of the blanking cylinder 1. A quantitative hole 7 adapted to the blanking hole 5 is radially opened on the upper end surface of the quantitative block 6. A slider 8 is slidably arranged in the quantitative hole 7 along the radial direction of the blanking cylinder 1. An adjusting device is arranged in the quantitative block 6, and the output end of the adjusting device is connected to the slider 8. A push plate 13 and a driving device are arranged on the lower end surface of the quantitative block 6, and the output end of the driving device is connected to the push plate 13.

[0030] During use, first, the driving device drives the push plate 13 to move inward, so that the push plate 13 seals the bottom end of the quantitative hole 7. The blanking cylinder 1 is filled with raw materials, which are generally a mixture of diamond particles and metal powder and added with binder resin. The sweeping rod 3 continuously rotates driven by the rotating shaft 2, so that the sweeping rod 3 drives the baffle 4 to push the raw materials in the blanking cylinder 1, so that the raw materials in the blanking cylinder 1 are filled into the pre-storage space 9 formed by the quantitative hole 7 and the slider 8 through the blanking hole 5. The pre-storage space 9 formed by the quantitative hole 7 and the slider 8 is the set amount of raw materials. When the mold conveyor belt 10 below conveys the mold 23 and stops below the quantitative hole 7, the driving device drives the push plate 13 to move outward, opening the bottom end of the quantitative hole 7. The raw materials in the pre-storage space 9 formed by the quantitative hole 7 and the slider 8 then fall downward into the mold 23 below, achieving the purpose of quantitatively feeding the mold 23.

[0031] When it is necessary to adjust the amount of materials fed into the mold 23, the slider 8 is driven to move in the quantitative hole 7 through the adjusting device, so as to achieve the purpose of making the pre-storage space 9 formed by the slider 8 and the quantitative hole 7 larger or smaller. Furthermore, the purpose of making the amount of raw materials filled in the pre-storage space 9 formed by the slider 8 and the quantitative hole 7 more or less is achieved. Furthermore, the purpose of adjusting the amount of raw materials falling into the mold 23 below is achieved, so that the blanking cylinder 1 can adapt to the production of cutting discs of different specifications, improving the practicability.

[0032] In this embodiment, the adjusting device includes a threaded rod 11 threadedly connected to the quantitative block 6, and the inner end of the threaded rod 11 is rotatably connected to the slider 8. When it is necessary to adjust the size of the pre-storage space 9 formed by the inner side surface of the slider 8 and the quantitative hole 7, the threaded rod 11 is rotated, so that the threaded rod 11 moves outward or inward, and then the threaded rod 11 drives the slider 8 to move in the quantitative hole 7, achieving the purpose of adjusting the size of the pre-storage space 9 formed by the inner side surface of the slider 8 and the quantitative hole 7.

[0033] In this embodiment, the driving device includes a hydraulic telescopic rod 12 fixedly arranged on the lower end surface of the metering block 6. The output end of the hydraulic telescopic rod 12 is fixedly connected to the push plate 13, and the upper end surface of the push plate 13 is slidably connected to the lower end surface of the metering block 6. When the mold conveyor belt 10 stops transporting the mold 23 below the metering hole 7, the hydraulic telescopic rod 12 drives the push plate 13 to move outwards, opening the bottom end of the metering hole 7, and the raw material in the pre-storage space 9 formed by the metering hole 7 and the slider 8 falls down into the lower mold 23, achieving the purpose of quantitatively feeding the mold 23.

[0034] In this embodiment, an L-shaped rod 14 is fixedly arranged inside the metering block 6, and the vertical part of the L-shaped rod 14 is located inside the metering hole 7. The threaded rod 11 is threadedly connected to the vertical part of the L-shaped rod 14, and the fixed end of the hydraulic telescopic rod 12 is fixedly arranged on the inner side surface of the vertical part of the L-shaped rod 14. The metering block 6 is threadedly connected to the L-shaped rod 14 and fixedly connected to the hydraulic telescopic rod 12 through the L-shaped rod 14.

[0035] In this embodiment, a frustum 15 is coaxially arranged on the inner bottom wall of the blanking cylinder 1. The frustum 15 is fixedly arranged on the inner bottom wall of the blanking cylinder 1, and the rotating shaft 2 is rotatably connected to the frustum 15. The lower end surface and the side surface of the sweeping rod 3 are respectively in sliding contact with the inner bottom wall of the blanking cylinder 1 and the side surface of the frustum 15. When the rotating shaft 2 rotates, the baffle 4 is driven to rotate by the sweeping rod 3, so that the baffle 4 pushes the raw material in the blanking cylinder 1 to move, facilitating the filling of the raw material into the pre-storage space 9 formed by the inner side surfaces of the metering block 6 and the slider 8.

[0036] In this embodiment, a motor 16 is fixedly arranged on the lower end surface of the blanking cylinder 1, and the output shaft of the motor 16 is fixedly connected to the rotating shaft 2. The motor 16 rotates to drive the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the sweeping rod 3 and the baffle 4 to rotate.

[0037] In order to increase the smoothness of the movement of the slider 8 in the metering hole 7, in this embodiment, guide blocks 17 are fixedly arranged on both side surfaces of the slider 8 in contact with the metering hole 7, and guide grooves 18 adapted to the guide blocks 17 are formed at the positions corresponding to the guide blocks 17 on the inner side wall of the metering hole 7. When the slider 8 slides, the guide blocks 17 move in the guide grooves 18, increasing the smoothness of the movement of the slider 8.

[0038] Since the inner side wall of the metering hole 7 is provided with a guide groove 18, it is not convenient to calculate the size of the pre-storage space 9 formed by the metering hole 7 and the inner side surface of the slider 8. To solve this problem, in this embodiment, a filling block 19 with an outer side surface flush with the inner side wall of the metering hole 7 is slidably arranged in the guide groove 18 of the metering hole 7 located inside the guide block 17. A spring 20 is fixedly arranged between the filling block 19 and the guide block 17. When the slider 8 is moved inward, the pre-storage space 9 formed by the inner side surface of the slider 8 and the metering hole 7 becomes smaller. At the same time, the slider 8 drives the guide block 17 to move inward to compress the spring 20, so that the spring 20 always pushes the filling block 19 inward, making the filling block 19 always located in the guide groove 18 inside the pre-storage space 9. When the slider 8 is moved outward, the pre-storage space 9 formed by the inner side surface of the slider 8 and the metering hole 7 becomes larger. At the same time, the degree of compression of the spring 20 decreases, but the spring 20 still pushes the filling block 19 inward, making the filling block 19 always located in the guide groove 18 inside the pre-storage space 9, realizing the filling of the guide groove 18 by the filling block 19, and facilitating the calculation of the size of the pre-storage space 9 formed by the inner side surface of the slider 8 and the metering hole 7.

[0039] In order to increase the smoothness of the movement of the baffle 4, in this embodiment, guide rails 21 are fixedly arranged along the radial direction of the blanking cylinder 1 at the lower end surfaces of the metering blocks 6 located on both sides of the metering hole 7. Two chutes adapted to the guide rails 21 are provided on the upper end surface of the baffle 4. The baffle 4 is slidably connected to the metering blocks 6 through the guide rails 21 and the chutes. When the baffle 4 moves, the smoothness of the movement of the baffle 4 is increased through the cooperation of the chute of the baffle 4 and the guide rail 21.

[0040] In this embodiment, a feeding hopper 22 is hinged to the upper end surface of the blanking cylinder 1. The feeding hopper 22 and the blanking cylinder 1 are fixedly closed together through a locking device, which is convenient for opening the feeding hopper 22 to clean the inside of the blanking cylinder 1.

[0041] The working principle of the present utility model: When in use, first, the hydraulic telescopic rod 12 drives the push plate 13 to move inward, so that the push plate 13 seals the bottom end of the metering hole 7. The raw materials are filled into the blanking cylinder 1 through the feeding hopper 22. The raw materials are generally a mixture of diamond particles and metal powder and added with binder resin. The motor 16 is started to drive the rotating shaft 2 to rotate, and the sweeping rod 3 continuously rotates driven by the rotating shaft 2, so that the sweeping rod 3 drives the baffle 4 to push the raw materials in the blanking cylinder 1 to move, so that the raw materials in the blanking cylinder 1 are filled into the pre-storage space 9 formed by the metering hole 7 and the slider 8 through the blanking hole 5. When the mold conveyor belt 10 below conveys the mold 23 and stops below the metering hole 7, the hydraulic telescopic rod 12 drives the push plate 13 to move outward, opening the bottom end of the metering hole 7. The raw materials in the pre-storage space 9 formed by the metering hole 7 and the slider 8 then fall downward into the mold 23 below, realizing the purpose of quantitatively feeding the raw materials into the mold 23.
