Technical Field

[0001] The utility model relates to the technical field of grinding wheel manufacturing and forming, in particular to an electromagnetic purification grinding wheel forming device. Background Art

[0002] In the production process of resin grinding wheels, molding materials are added into a molding die. The die rotates, and a scraper descends to level the materials and then ascends. After that, a hydraulic press is used to apply a certain pressure to make the loose granular molding materials in the die meet the density requirements, and a blank with uniform density is formed according to the size of the die. The precise control of this process plays a key role in the hardening density of the grinding wheel. However, due to the influence of the external environment and molding materials, metal particles and scraper residues will affect the uniformity during the material spreading process.

[0007] Further, the electromagnetic purification device includes an electromagnetic chuck and a recovery bucket. The electromagnetic chuck is arranged directly above the end of the feeding device and is slidably matched with a horizontal slide rail through a slider. The horizontal slide rail is fixedly connected to the workbench through a first fixing block, and the recovery bucket is arranged below the other end of the horizontal slide rail.

[0008] Based on the above, the specific design of the electromagnetic purification device, especially the combination of the electromagnetic chuck and the recovery bucket, and the sliding cooperation through the slider and the horizontal slide rail, realizes the automatic adsorption and recovery of metal particles or impurities, with simple operation and high efficiency.

[0016] Based on the above, through the combined use of the first conveyor belt, the second conveyor belt and the rotating motor, the precise positioning and rotary processing of the mold are realized. The setting of the auxiliary rollers ensures the stable operation of the conveyor belt, improving the stability and reliability of the conveying. The introduction of the rotating platform and the auxiliary positioning components further improves the processing accuracy and efficiency of the mold.

[0017] Further, each of the auxiliary positioning components includes a fork with a connecting rod and a roller rolling fit at the end of the fork. Each connecting rod passes through a guiding groove disposed on the workbench and is respectively connected to the output end of a linear motor in the workbench. During material spreading, the rotating platform drives the mold to rotate, and the linear motor drives the fork to move synchronously towards the mold, and then the roller is in close contact with the outer edge of the mold and rotates freely.

[0018] Based on the above, by driving the fork and the roller to move closely along the outer edge of the mold by the linear motor, the stable positioning of the mold during the rotary processing is realized. The free rotation of the roller reduces the friction with the mold and prolongs the service life of the mold. This design improves the processing accuracy and stability of the mold, ensuring the quality of the grinding wheel forming.

[0019] Further, baffles are also disposed on both sides of the workbench along the conveying device.

A scraper 43 is fixedly connected to the clamping block 42. When the second cylinder 41 retracts, the scraper 43 is located above the brush head 68.

[0037] As Figure 7As shown, the conveying device 2 includes a first conveyor belt 21, a second conveyor belt 22, and a rotating motor 23.
