Description

Technical Field

[0001] The present application relates to the technical field of resin grinding wheel production, and specifically relates to a resin grinding wheel forming device. Background Art

[0002] A resin grinding wheel is a grinding wheel made of resin, with high strength, and is applied to cutting discs, double-sided discs, heavy-duty grinding wheels, polishing wheels, etc. It has certain elasticity, low heat resistance, good self-sharpening property, simple production, and short process cycle; it is widely used in rough grinding, snag grinding, cutting, and free grinding, such as grinding steel ingots and deburring castings.

[0003] The existing patent (publication number: CN 216883434 U) discloses a resin grinding wheel hot pressing and forming device, including a base and a top plate. Both the left and right sides of the bottom of the base are provided with two bottom columns distributed symmetrically in the front and back. Both the left and right sides of the top of the base are provided with two support columns distributed symmetrically in the front and back. The top plate is located above the support columns, and the left and right sides of its bottom are respectively fixedly connected to the left and right support columns. In this resin grinding wheel hot pressing and forming device, by rotating the rotating rod, the second bevel gear drives the first bevel gear to mesh and rotate, thereby driving the threaded rod to rotate, causing the threaded block to move on the threaded rod, prompting the wedge-shaped sleeve to move. The wedge-shaped sleeves on both the left and right sides move away from each other, causing the jacking rod to slide on the wedge-shaped sleeve. The upward movement of the jacking rod can demold the resin grinding wheel after hot pressing, achieving the purpose of automatic demolding, avoiding manual demolding, and improving the demolding efficiency.

[0004] Although the above-mentioned grinding wheel forming device can demold automatically, the temperature of the grinding wheel after hot pressing is relatively high, which is not convenient for blanking, affects the subsequent production of grinding wheels, and reduces the operation efficiency.

[0017] Through the above solution, the mold is restricted to prevent it from rotating relative to the sliding rod during movement, thereby increasing the stability of the mold movement.

[0018] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each rotating shaft, the outer circumferential surface of the limiting ring is rotatably connected to the inside of the bottom plate, and a motor is provided at the bottom of one of the rotating shafts.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 4 A collar 10 is fixedly sleeved on the outer circumferential surface of each mold 7. A chute 11 is opened inside the track frame 9. The outer surface of the collar 10 is slidably connected to the track frame 9 through the chute 11, so that the mold 7 always follows the collar 10 to perform circular motion along the chute 11, increasing the stability of the movement of the mold 7.

[0033] Please refer to Figure 1 and Figure 2 A lifting block 13 is fixedly connected to the bottom surface of each slide bar 6. The lifting block 13 is of an isosceles trapezoid structure. A lifting plate 14 is fixedly connected to the upper surface of the bottom plate 1. The top end of the lifting plate 14 is of an isosceles trapezoid structure. Through the interaction between the lifting block 13 and the lifting plate 14, the top plate 8 can be automatically lifted by a certain distance, and then the grinding wheel can be automatically demolded, facilitating the feeding of the grinding wheel.

[0034] Please refer to Figure 4 , a spring 15 is fixedly connected to the upper surface of each lifting block 13, and the top end of the spring 15 is fixedly connected to the bottom surface of the base 5. The spring 15 can exert a reaction force on the sliding rod 6 to prompt the top plate 8 to automatically move back.

[0035] Please refer to Figure 4 , two first side plates 16 are fixedly connected to the outer circumferential surface of each sliding rod 6, and the outer surface of each first side plate 16 is slidably connected to the inside of the base 5 to restrict the sliding rod 6 from rotating and increase the stability of the sliding rod 6 during movement.

[0036] Please refer to Figure 4 , two second side plates 17 are fixedly connected to the outer circumferential surface of each sliding rod 6, and the outer surface of each second side plate 17 is slidably connected to the inside of the mold 7 to restrict the mold 7 from rotating relative to the sliding rod 6 during movement and increase the stability of the mold 7 during movement.

[0037] Please refer to Figure 3 , a limit ring 18 is fixedly sleeved on the outer circumferential surface of each rotating shaft 2, and the outer circumferential surface of the limit ring 18 is rotatably connected to the inside of the bottom plate 1. A motor 19 is provided at the bottom of one of the rotating shafts 2. The limit ring 18 can restrict the rotating shaft 2 from easily falling off, and the motor 19 can provide power for one of the rotating shafts 2, and then drive the transmission chain 4 to operate through the sprocket 3.

[0038] Please refer to Figure 1 , a hydraulic cylinder 21 is provided above the bottom plate 1, and the output end of the hydraulic cylinder 21 is fixedly connected to a pressing piece 22. The hydraulic cylinder 21 drives the pressing piece 22 to lift and lower, thereby completing the hot pressing forming operation of the grinding wheel.

[0039] In a resin grinding wheel forming device in this embodiment, during the operation of the transmission chain 4, the mold 7 is driven to perform a cyclic movement, so that the grinding wheel hot-pressed and formed in the mold 7 can sequentially pass through the inside of the heat dissipation device 12, achieving the effect of being able to cool the grinding wheel formed in the mold 7, facilitating the blanking of the formed grinding wheel, and enabling the batch production of the grinding wheel, improving the operation efficiency, and solving the problem that the temperature of the grinding wheel after hot pressing is relatively high, which is not conducive to blanking, affecting the subsequent production of the grinding wheel, and reducing the operation efficiency.

[0040] It should be noted that the length of the upper surface of the lifting plate 14 should not be too short, so that the top plate 8 can be lifted for a longer time, thereby leaving enough time for the worker to perform blanking.

[0041] The working principle of the above embodiment is as follows:

[0042] The feeding pipe 20 is connected to an external feeding device. When the forming operation of the resin grinding wheel is required, the motor 19 is started as the power to drive one of the rotating shafts 2 to rotate. The rotating shaft 2 drives the transmission chain 4 to operate through the sprocket 3. The transmission chain 4 drives the sliding rod 6 to perform a cyclic motion through the base 5. The sliding rod 6 drives the mold 7 to perform a cyclic motion. When the mold 7 passes through the feeding pipe 20, the transmission chain 4 stops operating. The external feeding device injects raw materials into the mold 7 through the feeding pipe 20. Then the transmission chain 4 continues to operate. When the mold 7 filled with raw materials moves below the pressing plate 22, the transmission chain 4 stops operating. The hydraulic cylinder 21 drives the pressing plate 22 to move downward to perform a hot pressing operation on the raw materials in the mold 7. During the hot pressing operation, the feeding device at the rear will start to feed the mold 7 at the rear through the feeding pipe 20. After the grinding wheel is hot pressed and formed, the hydraulic cylinder 21 will drive the pressing plate 22 to move upward, and the transmission chain 4 will continue to operate. Along with the alternating operations of the transmission chain 4, the external feeding device, the feeding pipe 20, the hydraulic cylinder 21, and the pressing plate 22, the grinding wheel completes continuous batch production. When the mold 7 passes through the inside of the heat dissipation device 12, the heat dissipation device 12 will cool the formed grinding wheel in the mold 7 to facilitate blanking. When the lifting block 13 passes through the position of the lifting plate 14, it will move upward under the action of the lifting plate 14, and then drive the top plate 8 to move upward through the sliding rod 6. Immediately, the top plate 8 lifts the formed grinding wheel to a certain height, prompting the grinding wheel to be automatically demolded. At this time, the worker can remove the demolded grinding wheel.
