[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 8 shown, the present invention provides a technical solution for a diamond dual-purpose grinding disc processing device and a processing method: a diamond dual-purpose grinding disc processing device, including a diamond grinding disc, refer to Figure 1 and Figure 2 , and the diamond grinding disc processing device refer to Figures 3 to 8 .

[0039] Embodiment 1

[0040] Refer to Figure 1 and Figure 2 , the diamond grinding disc includes a fixing piece 1 and a grinding piece 2. The fixing piece 1 is above the grinding piece 2. A plurality of slits 3 are formed on the surface of the grinding piece 2. The slits 3 penetrate through the upper and lower ends of the grinding piece 2 and extend towards the center of the grinding piece 2. While extending towards the center of the grinding piece 2, the width of the slits 3 gradually decreases. Both side ends of the slits 3 are inclined. A protrusion facing the fixing piece 1 is formed on the surface of the grinding piece 2. At the same time, another protrusion with the same direction as the protrusion on the grinding piece 2 is formed on the surface of the fixing piece 1. The protrusion on the grinding piece 2 is stuck into the fixing piece 1. In addition, a plurality of clamping blocks 5 are formed on the lower surface of the fixing piece 1. The clamping blocks 5 are adapted to the slits 3 in the part below the fixing piece 1. The clamping blocks 5 are stuck into the slits 3. Note that the grinding piece 2 is made of seed material and base material. The main body of the seed material is diamond powder, as well as auxiliary materials such as ceramic powder and metal powder. The base material is resin containing a large amount of bronze powder. The seed material is concentrated on the bottom surface and the edge of the grinding piece 2. A cutting edge 4 is ground on the edge of the grinding piece 2.

[0041] The bottom surface and the edge of the grinding piece 2 are enriched with diamond powder seed material, making both positions have extremely high strength and wear resistance. The bottom surface position can be used for grinding, and the cutting edge 4 formed on the edge can be used for cutting. Note that during the grinding operation, the slits 3 formed on the grinding piece 2, because both side edges of the slits 3 are inclined, during the grinding operation, the raised parts on the surface of the grinding object can be removed faster at the slits 3, so as to improve the efficiency of grinding the object. However, note that when the slits 3 grind the raised objects, some impurities may splash. When in use, it is necessary to pay attention to using a grinding machine with a protective cover function.

[0042] Embodiment 2

[0043] Refer to Figures 3 to 7, The processing device includes an upper mold 10 and a lower mold 13. Both the upper mold 10 and the lower mold 13 are installed on a press 6. The upper mold 10 is hoisted and pressed downwards, and the lower mold 13 is pressed upwards from the inside. At the same time, the upper mold 10 is in a rotatable state. When the upper mold 10 is docked with the lower mold 13, the internal space formed is in a state adapted to the outer shape of the grinding disc 2, but there is a structure inside that forms a notch 3. There are several extension arms 7 provided on the press 6. The number of extension arms 7 corresponds to the number of notches 3, and the extension arms 7 surround the lower mold 13. A guide rail 21 is provided on the surface of the extension arm 7, and a movable member 8 is slidably installed in the guide rail 21. A plug-in member 24 is installed at the end of the movable member 8. The outer shape structure of the plug-in member 24 is adapted to the notch 3. Sockets 14 are provided on both the upper mold 10 and the lower mold 13. The plug-in member 24 is completely inserted between the upper mold 10 and the lower mold 13 from the socket 14. A base material pipe 11 is installed on the upper mold 10. The base material pipe 11 is connected to the external base material to inject resin into the mold. Above the outer side of the contact surface between the upper mold 10 and the lower mold 13, a suspension rail 9 is hoisted. A spraying tool 12 slides on the suspension rail 9. A guiding member 16 is installed below the spraying tool 12. The guiding member 16 rotates around the suspension rail 9. The spraying tool 12 is rotatably installed on the guiding member 16. At the same time, the tail of the spraying tool 12 is connected to a seed material pipe 15. The seed material pipe 15 transports diamond powder. The front end of the spraying tool 12 is connected to a connecting member 17 through an electric control telescopic arm 20. A spray nozzle 18 is provided on the connecting member 17. At the same time, the spray nozzle 18 is connected to the seed material pipe 15 through a conduit 19.

[0044] When the device works, the lower mold 13 first rises to a state where the plug-in member 24 can be inserted into the socket 14. After the plug-in member 24 is inserted into the socket 14 on the lower mold 13, the upper mold 10 descends. Note that at this time, the upper mold 10 and the lower mold 13 do not come into complete contact. The external pump works and injects the base material through the base material pipe 11. The base material falls into the lower mold 13. At this time, the upper mold 10 keeps rotating so that the base material injected from the base material pipe 11 can be evenly distributed on the lower mold 13. Due to the certain tension of the liquid resin and the limitation of the plug-in member 24 at the edge, a slightly more amount of resin can be injected. When the resin flows into a flat state, the spraying tool 12 works. It rotates around the suspension rail 9 through the guiding member 16. During the rotation process, seeds are synchronously injected onto the resin surface to keep the seeds evenly injected. After the seeds are injected, the upper mold 10 descends to contact the lower mold 13, and then rotates slightly to completely clamp the socket 14 on the upper mold 10 onto the plug-in member 24. At this time, the upper mold 10 and the lower mold 13 are in a completely tightly docked state. Then, continue to inject the base material into the mold to ensure that the base material in the mold is full, and then continue cold pressing.

[0045] Example 3

[0046] Refer to Figure 7 and Figure 8, the press 6 is internally provided with a vibrator, the upper mold 10 and the lower mold 13 vibrate synchronously. Two push rods 23 are provided at the tail of the movable part 8. A first spring 22 is sleeved outside the push rod 23. A limit plate 25 is provided at the end of the plug-in part 24. There is a cavity 28 stuck inside the movable part 8. The limit plate 25 is inside the cavity 28, and the front opening size of the cavity 28 is smaller than the limit plate 25. When the limit plate 25 is inside the cavity 28, there are spare spaces above, below, on both sides. A limit rod 26 is provided at the tail of the limit plate 25. A second spring 27 is sleeved outside the limit rod 26. The end of the second spring 27 is fixed on the limit plate 25, and the length of the limit rod 26 is shorter than that of the second spring 27. A fixed seat 30 is installed at the inner end of the cavity 28. A telescopic sleeve rod 29 moves back and forth inside the fixed seat 30. The telescopic sleeve rod 29 is electrically controlled. The second spring 27 is sleeved into the telescopic sleeve rod 29, and the diameter of the telescopic sleeve rod 29 is the same as that of the second spring 27.

[0047] The vibrator works, so that the molds after injecting the seed materials can vibrate together. Through vibration, the seed materials move in the liquid resin, and their moving direction is the same as the density of the resin. By adjusting the resin density, the position of the seed materials in the resin can be changed, causing them to sink or rise. The amount of their movement is related to the vibration time. By vibrating, the position of the seed materials is changed, making the positions of the seed materials in the produced abrasive tools more concentrated. At the same time, the concentrated points can be set according to actual use requirements, which is convenient for use.

[0048] When the upper mold 10 and the lower mold 13 vibrate, if the plug-in part 24 cannot be adapted, the notch 3 cannot be formed, and at the same time, the amount of the injected base material cannot meet the production requirements. By controlling the position of the telescopic sleeve rod 29, when the telescopic sleeve rod 29 is only sleeved outside the second spring 27 and does not move outside the limit rod 26, the plug-in part 24 is in a vibratable state at this time. The second spring 27 between the limit rod 26 and the telescopic sleeve rod 29 can vibrate, which is convenient for the plug-in part 24 to adapt to the vibration requirements. However, in the case of initially injecting the base material, it is necessary to prevent the plug-in part 24 from shifting, and its position needs to be kept stable. At this time, the telescopic sleeve rod 29 moves forward and is sleeved outside the limit rod 26. At this time, the plug-in part 24 remains stable, so that the injected base material is also stably in the mold, and it can be prevented from seeping into the gap between the plug-in part 24 and the lower mold 13.

[0049] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.

[0050] In the description of the present invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.
