Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding wheel production, in particular to a diamond grinding wheel mold cooling device. Background Art

[0002] The preparation steps of diamond grinding wheels usually include placing the abrasive and the base in a mold and cold pressing them into shape. The mold is then placed in a furnace for sintering. After sintering, the mold is removed from the sintering furnace and demolded to obtain a semi-finished product. After the semi-finished product cools, it is further processed and shaped to obtain a diamond grinding wheel.

[0003] Since the sintering process temperature is above 650°C, the mold still maintains a high temperature after being taken out of the sintering furnace and the semi-finished product is demolded. It is necessary to wait for the mold to cool down before it can be put into the next round of production. It takes a long time for the mold to cool down naturally to room temperature, resulting in reduced production efficiency. In addition, stacking the molds together during the waiting period is not conducive to rapid heat dissipation of the molds, and placing them separately will take up a large space, making it inconvenient for production operations.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown, the embodiment of the utility model proposes a diamond grinding wheel mold cooling device, which is used to cool the diamond grinding wheel mold after sintering to remove the semi-finished diamond grinding wheel, so that the temperature of the diamond grinding wheel mold drops quickly and is put into the next round of production.

[0023] Please refer to Figure 1 and Figure 2 The diamond grinding wheel mold cooling device includes a frame 1 and a water tank 2, the water tank 2 is filled with a liquid cooling medium, and the cooling medium is water. The frame 1 is provided with a liftable lifting frame 3 and a first driving component 4 connected to the lifting frame 3, the lifting frame 3 includes a placement plate 31 and a vertical plate 32 perpendicular to each other, the diamond mold to be cooled is placed on the placement plate 31, the placement plate 31 is located directly above the water tank 2 and a plurality of first slots 33 are provided on the placement plate 31 at intervals. When the first driving component 4 drives the lifting frame 3 to rise and fall in the vertical direction, the placement plate 31 withdraws from or extends into the water tank 2, and when the lifting frame 3 descends, the placement plate 31 and the diamond grinding wheel mold placed on the placement plate 31 are immersed in the water tank 2. In the cooling medium, when the lifting frame 3 rises, the placement plate 31 together with the diamond grinding wheel mold placed on the placement plate 31 is taken out of the water tank 2, and a plurality of second slots 34 are provided at intervals on the vertical plate 32. The frame 1 is also provided with a blowing assembly 5, and the blowing assembly 5 includes a blowing bracket 51. The blowing bracket 51 is provided with a connected air guide 52 and a fan. The air guide 52 is located on the side of the vertical plate 32 away from the placement plate 31 and the opening of the air guide 52 faces the second slot 34. The airflow blown by the fan can pass through the second slot 34 along the air guide 52 and contact the diamond grinding wheel mold placed on the placement plate 31 to dry the cooling medium on the surface of the diamond grinding wheel mold and accelerate the drying of the diamond grinding wheel mold.

[0024] Specifically, the operation steps of cooling the diamond grinding wheel mold using the diamond grinding wheel mold cooling device provided in this embodiment are as follows: placing the diamond grinding wheel mold to be cooled on the placement plate 31, starting the first driving component 4 to drive the lifting frame 3 to descend in the vertical direction and immerse the placement plate 31 in the water tank 2, at this time, the diamond grinding wheel mold contacts the cooling medium in the water tank 2 so that the heat of the diamond grinding wheel mold is transferred to the cooling medium so that the diamond grinding wheel mold is quickly cooled, and after the diamond grinding wheel mold is cooled, the first driving component 4 is driven to The lifting frame 3 is raised in the vertical direction. At this time, the placement plate 31 is moved to the outside of the water tank 2 and the diamond grinding wheel mold is taken out of the cooling medium. The cooling medium on the diamond grinding wheel mold passes through the first slot 33 under the action of gravity and falls into the water tank 2. Then the fan is started so that the air flow blown out by the fan passes through the second slot 34 along the air guide 52 and acts on the diamond grinding wheel mold to accelerate the drying of the diamond grinding wheel mold. After the diamond grinding wheel mold is dried, the diamond grinding wheel mold is removed from the placement plate 31 and can be put into the next round of production. The diamond grinding wheel mold cooling device provided in this embodiment quickly cools the diamond grinding wheel mold by placing the diamond grinding wheel mold into the cooling medium in the water tank 2, effectively improving the cooling efficiency of the diamond grinding wheel mold and avoiding the space occupied by the diamond grinding wheel mold during the cooling process to affect the production operation, which is conducive to improving the production efficiency of the diamond grinding wheel.

[0025] like Figure 1 and Figure 3 As shown, the frame 1 is provided with a guide rail 11, the length direction of which is consistent with the vertical direction, and the vertical plate 32 is provided with a slider 39 that cooperates with the guide rail 11. The guide rail 11 provided on the frame 1 guides the movement of the lifting frame 3 on the frame 1, preventing the lifting frame 3 from deviating from the preset direction during movement, ensuring that the placement plate 31 smoothly enters or exits the water tank 2 when the lifting frame 3 is raised or lowered in the vertical direction. The slider 39 provided on the vertical plate 32 cooperates with the guide rail 11 to reduce friction between the lifting frame 3 and the frame 1, thereby improving the stability of the lifting frame 3 during movement.

[0026] like Figure 2 and Figure 3As shown, the first drive assembly 4 includes a first motor 41 and a drive screw 42 drivingly connected to the output end of the first motor 41. The drive screw 42 is rotatably mounted on the frame 1, with the axial direction of the drive screw 42 aligned with the vertical direction. A connecting plate 35 is provided at the end of the vertical plate 32 away from the placement plate 31. The connecting plate 35 has a threaded hole 36 that engages with the drive screw 42. When the first motor 41 drives the drive screw to rotate, the threaded hole 36 engages with the drive screw 42 to drive the connecting plate 35 along the axial direction of the drive screw 42, thereby driving the lifting frame 3 to move vertically and adjust its position. The threaded hole 36 engages with the drive screw 42 to lock the position of the lifting frame 3, allowing the lifting frame 3 to remain in the position where the placement plate is located within or above the water tank 2, thereby ensuring that the diamond grinding wheel mold remains immersed in the cooling medium and facilitating the removal and placement of the diamond grinding wheel mold.

[0027] Specifically, a first sprocket 43 is provided at the output end of the first motor 41, and a second sprocket 44 is provided at one end of the drive screw 42. The first sprocket 43 and the second sprocket 44 are connected by a transmission chain 45. When the first motor 41 drives the first sprocket 43 to rotate, the transmission chain 45 transmits the power output by the first motor 41 to the second sprocket 44, driving the second sprocket 44 to rotate, thereby driving the drive screw 42 to rotate and adjust the position of the lifting frame 3, ensuring that the power output by the first motor 41 is smoothly transmitted to the drive screw 42.

[0028] Please refer to Figure 1 and Figure 4 The lifting frame 3 further includes two side baffles 37 vertically disposed on the placement plate 31. The two side baffles 37 are located on opposite sides of the placement plate 31 and are fixedly connected to the vertical plates 32. The side baffles 37 disposed on both sides of the placement plate 31 are used to block the diamond grinding wheel mold placed on the placement plate 31, preventing the diamond grinding wheel mold from sliding off the placement plate 31 during movement of the lifting frame 3, thereby maintaining a stable position of the diamond grinding wheel mold on the lifting frame 3.

[0029] Specifically, each of the two side baffles 37 is provided with a through slot 38, and the through slot 38 is located on a side of the side baffle 37 close to the vertical plate 32. The through slots 38 are provided on the side baffles 37 to reduce the overall weight of the lifting frame 3, thereby preventing the diamond grinding wheel mold cooling device from being damaged due to the excessive weight of the lifting frame 3 and the diamond grinding wheel mold after the diamond grinding wheel mold is placed on the placement plate 31.

[0030] Please combine Figure 1 and Figure 4 The placement plate 31 is provided with a rotatable support plate 6, and the support plate 6 is provided with a plurality of third slots 61 extending therethrough at intervals. The lifting frame 3 is further provided with a second drive assembly 7 in transmission connection with the support plate 6, and the second drive assembly 7 drives the end of the support plate 6 away from the vertical plate 32 to move closer to or away from the vertical plate 32. The rotatable support plate 6 is provided on the placement plate 31. After the diamond grinding wheel mold is placed on the support plate 6, the support plate 6 is driven by the second drive assembly 7 to rotate, thereby tilting the diamond grinding wheel mold so that the airflow blown by the fan can act on the top surface of the diamond grinding wheel mold, further accelerating the drying of the diamond grinding wheel mold. When the placement plate 31 is driven by the first drive assembly 4 to exit the water tank 2, part of the cooling medium on the diamond grinding wheel mold passes through the third slots 61 and the first slots 33 in sequence and falls into the water tank 2, thereby preventing water accumulation on the support plate 6 from affecting the drying of the diamond grinding wheel mold.

[0031] In this embodiment, the second drive assembly 7 includes a second motor 71 and a winch 72 disposed at the output end of the second motor 71. A steel wire rope 73 is wound around the winch 72, and one end of the steel wire rope 73 is fixedly connected to the support plate 6. The second motor 71 drives the winch 72 to rotate, tightening the steel wire rope 73 on the winch 72. This allows the support plate 6 to rotate via the steel wire rope 73, causing the support plate 6 to tilt at a certain angle relative to the placement plate 31. When the support plate 6 needs to be reset, the second motor 71 drives the winch 72 to rotate in the opposite direction, slowly unwinding the steel wire rope 73. At this point, the support plate 6 rotates and resets under the action of its own weight until it is in contact with the placement plate 31.

[0032] like Figure 4 As shown, the lifting frame 3 is provided with a fixed pulley 8, which abuts the steel wire rope 73. The fixed pulley 8 is provided on the lifting frame 3 to abut the steel wire rope 73 to keep the steel wire rope 73 taut and prevent the steel wire rope 73 from shaking when the winch 72 is driven by the second motor 71 to rotate, thereby ensuring that the support plate 6 remains stable during rotation and preventing the diamond grinding wheel mold from falling off the support plate 6.

[0033] Please refer to Figure 1The blowing assembly 5 further includes an air uniforming plate 53 provided on the blowing bracket 51. The air uniforming plate 53 is located between the vertical plate 32 and the air guide hood 52 and covers the opening of the air guide hood 52. The air uniforming plate 53 provided on the blowing bracket 51 is used to allow the air flow blown out of the air guide hood 52 to blow smoothly toward the diamond grinding wheel mold placed on the placement plate 31, so that multiple diamond grinding wheel molds placed at different positions on the placement plate 31 can all be affected by the air flow blown out by the fan, so that when the diamond grinding wheel mold cooling device cools multiple diamond grinding wheel molds at the same time, multiple diamond grinding wheel molds can all be quickly dried, which is beneficial to improving the working efficiency of the diamond grinding wheel mold cooling device.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
