Description

Technical Field

[0001] This utility model relates to the field of diamond grinding wheel production technology, specifically a diamond grinding wheel forming device. Background Technology

[0002] Diamond grinding wheels are circular bonded abrasives made with diamond abrasive as the core material and binders such as metal powder, resin powder, ceramic, or electroplated metal. They usually have a through hole in the center. Their characteristics include high wear resistance, high efficiency, high machining accuracy, and good thermal conductivity. They are suitable for grinding hard and brittle materials such as cemented carbide, glass, and ceramics. Depending on the binder, diamond grinding wheels can be divided into resin-bonded, ceramic-bonded, and metal-bonded types. They are widely used in fine grinding, semi-fine grinding, and cutting processes in industrial fields. In the production process of diamond grinding wheels, they need to be cold-pressed.

[0003] The existing publication number CN218020379U discloses a diamond grinding wheel cold pressing forming device. Through the coordinated arrangement of a fixing component, a lifting component, a cooling component, and a driving component, the lifting component allows the upper mold to cover the grinding wheel in the forming cavity, using continuous downward pressure to extrude and shape the grinding wheel. The driving component delivers coolant from the cooling component to the cooling cavity during the extrusion of the grinding wheel by the upper mold, continuously cooling the grinding wheel during the shaping process, resulting in good cooling effect. Furthermore, the lower mold is fixed to the worktable by the fixing component, allowing multiple lower molds to be used in rotation. This enables the sintered grinding wheel in the lower mold to be placed on the worktable for cold pressing without the need for individual movement of the sintered grinding wheel, simplifying operation and increasing efficiency. However, this forming device cannot spray a release agent into the mold, causing the diamond grinding wheel to adhere to the inner wall of the mold after cold pressing, significantly reducing the release effect and negatively impacting practical use. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a diamond grinding wheel forming device, which has a spraying mechanism to uniformly spray a release agent onto the inner wall of the mold, thereby reducing the adhesion between the diamond grinding wheel and the mold, and thus improving the demolding effect after forming. This has certain beneficial effects on practical use and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diamond grinding wheel forming device, comprising a base, support rods fixedly installed on both sides of the top of the base, a top frame fixedly installed at the top of the support rods, a lower mold fixedly installed in the middle of the top of the base, a motor fixedly installed on the right side of the top of the top frame, a rotating shaft fixedly installed at the output end of the motor, a gear fixedly connected to the bottom end of the rotating shaft passing through the interior of the top frame, a gear ring movably meshing on the left side of the gear, an annular plate fixedly installed on the inner side of the gear ring, a liquid storage tank fixedly installed in the middle of the top of the top frame, flexible hoses penetrating through both sides of the bottom of the liquid storage tank, an infusion pipe penetrating through the bottom end of the flexible hose passing through the interior of the top frame, a nozzle fixedly connected to the other end of the infusion pipe passing through the annular plate, a hydraulic rod fixedly installed on the top of the inner wall of the top frame, and an upper mold fixedly installed at the bottom end of the hydraulic rod.

[0009] Preferably, a sealing sleeve is slidably connected to the outside of the top rod, and the sealing sleeve is fixedly connected to the inner wall of the cooling cavity.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: the release agent inside the storage tank can be delivered to the nozzle through a hose and an infusion pipe.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1, please refer to Figures 1 to 4This utility model provides a technical solution: a diamond grinding wheel forming device, including a base 1, support rods fixedly installed on both sides of the top of the base 1, a top frame 2 fixedly installed at the top of the support rods, a lower mold 3 fixedly installed in the middle of the top of the base 1, a motor 4 fixedly installed on the right side of the top of the top frame 2, a rotating shaft 5 fixedly installed at the output end of the motor 4, a gear 6 fixedly connected to the bottom end of the rotating shaft 5 through the interior of the top frame 2, a gear ring 7 movably meshing on the left side of the gear 6, an annular plate 8 fixedly installed on the inner side of the gear ring 7, a liquid storage tank 9 fixedly installed in the middle of the top of the top of the top frame 2, hoses 10 connected through the bottom of the liquid storage tank 9 on both sides, an infusion pipe 11 connected through the bottom end of the hoses 10 through the interior of the top frame 2, a nozzle 12 fixedly connected to the other end of the infusion pipe 11 through the annular plate 8, a hydraulic rod 13 fixedly installed on the top of the inner wall of the top frame 2, and an upper mold 14 fixedly installed at the bottom end of the hydraulic rod 13.

[0020] Furthermore, a threaded rod 15 is fixedly installed at the bottom of the gear 6. The bottom end of the threaded rod 15 is rotatably connected to the bottom of the inner wall of the base 1 through a bearing. A lifting plate 16 is threadedly connected to the outside of the threaded rod 15 and near its bottom end. A top rod 17 is fixedly installed at the top of the lifting plate 16. The top end of the top rod 17 is inserted into the inner side of the lower mold 3 and fixedly connected to a top plate 18. The top plate 18 can lift the cold-pressed diamond grinding wheel, thereby realizing the automatic demolding of the diamond grinding wheel and improving work efficiency.

[0021] Furthermore, a sliding sleeve 19 is fixedly installed on the left side of the lifting plate 16, and a sliding rod 20 is slidably connected to the inner side of the sliding sleeve 19. The two ends of the sliding rod 20 are fixedly connected to the upper and lower sides of the inner wall of the base 1, so that the lifting plate 16 can be stably raised and lowered under the sliding action of the sliding sleeve 19 and the sliding rod 20.

[0022] Furthermore, a cooling cavity 21 is provided inside the lower mold 3, and water pipes are connected to both sides of the cooling cavity 21. Cooling water can enter or exit the cooling cavity 21 through the water pipes, thereby achieving rapid cooling of the diamond grinding wheel inside the lower mold 3.

[0023] Example 2, please refer to Figures 1 to 4The difference between this embodiment and embodiment 1 is that: a sealing sleeve 22 is slidably connected to the outside of the push rod 17, and the sealing sleeve 22 is fixedly connected to the inner wall of the cooling cavity 21. The sealing sleeve 22 can improve the sealing between the push rod 17 and the lower mold 3, thereby preventing the cooling water in the cavity from overflowing. An inclined support rod 23 is fixedly installed inside the cooling cavity. The inclined support rod 23 is made of stainless steel and can support the cavity, thereby preventing the lower mold 3 from deforming during the diamond grinding wheel cold pressing process. A rotating groove is opened on the outer side of the annular plate 8 near its top. A rotating sleeve 24 is rotatably connected to the inner side of the rotating groove. L-shaped support rods are fixedly installed on both sides of the rotating sleeve 24. The other end of the L-shaped support rod is fixedly connected to the top of the inner wall of the top frame 2. Through the setting of the rotating groove and the rotating sleeve 24, the annular plate 8 can rotate stably.

[0024] Working Principle: In use, the release agent in the storage tank 9 is delivered to the nozzle 12 via the hose 10 and the delivery pipe 11. The nozzle 12 sprays the release agent. Simultaneously, the operator starts the motor 4, which drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the gear 6 to rotate, which in turn drives the gear ring 7 to rotate. The gear ring 7 then drives the annular plate 8, which in turn drives the nozzle 12. This allows the nozzle 12 to evenly spray the release agent onto the inner wall of the mold, reducing adhesion between the diamond wheel and the mold, thus improving the demolding effect after molding. After the release agent is sprayed, the operator can remove the molded parts. The cold-pressed diamond grinding wheel is placed in the lower mold 3, and cooling water enters or exits the cooling cavity 21 through the water pipe. Then, the operator can start the hydraulic rod 13, which drives the upper mold 14 to press the diamond grinding wheel inside the lower mold 3. After the diamond grinding wheel cools and forms, the operator can start the motor 4 again. The motor 4 drives the gear 6 to rotate, the gear 6 drives the threaded rod 15 to rotate, the threaded rod 15 drives the lifting plate 16 to rise and fall, the lifting plate 16 drives the top rod 17 to rise and fall, and the top rod 17 drives the top plate 18 to lift the cold-pressed diamond grinding wheel, thereby realizing the automatic demolding of the diamond grinding wheel and improving work efficiency.
