[0002] Corundum grinding wheels are made by mixing abrasive and a binder, then pressing, drying, and sintering to form a porous structure. Their performance is determined by factors such as the abrasive type, particle size, binder type, and shape. They can be categorized into over ten shapes, including flat, cylindrical, and disc-shaped. Bonds include ceramic, resin, and rubber. Before use, rotation and static balancing tests are required to ensure safety. During installation, the chuck diameter must match the grinding wheel size, and protective devices must be installed.

DETAILED DESCRIPTION

[0053] The present invention will be further described in detail below in conjunction with specific implementation methods to better demonstrate the advantages of the present invention.

[0054] Example 1: A corundum abrasive wheel pressing and forming device, such as Figure 1-Figure 5 As shown, it includes a workbench 1, four columns 2, a top beam 3, a movable platform 4, a hydraulic cylinder 5 and a grinding wheel mold 6. The lower ends of the four columns 2 are welded to the four corners of the top surface of the workbench 1, and the top beam 3 is welded to the upper ends of the columns 2, and the columns 2 are perpendicular to the workbench 1 and the top beam 3. The movable platform 4 has four circular holes through which the columns 2 pass, and is set on the columns 2 for sliding up and down. The hydraulic cylinder 5 is fixedly set on the top beam 3, and passes through the top beam 3 through the output shaft and is fixedly connected to the top surface of the movable platform 4. The grinding wheel mold 6 includes an upper mold 61 and a lower mold 62. A rotating base 7 is rotatably provided on the top surface of the workbench 1, on which two lower molds 62 can be placed circumferentially. That is, the two lower molds 62 are distributed at a 180° flat angle, and the upper mold 61 is arranged on the bottom surface of the movable platform 4 corresponding to the position of any lower mold 62. A power column 41 is vertically provided at the center of the bottom surface of the movable platform 4. A first through hole and a second through hole for the power column 41 to pass through are provided in the center of the rotating base 7 and the workbench 1, respectively.

[0055] like Figure 6-Figure 8 As shown, the inner annular surface of the first through hole and the side surface of the power column 41 are provided with guide grooves 71 and guide blocks 72 for cooperating with each other to rotate the rotating platform 7. There are two groups of guide grooves 71 and guide blocks 72, and they are arranged at 180 degrees to improve the driving stability of the power column 41. The guide groove 71 is a combined guide groove with an arc section and a vertical section as shown in the figure. The length of the arc section needs to be sufficient to allow the rotating platform 7 to rotate 180 degrees, and the length of the vertical section needs to be sufficient to allow the upper mold 61 and the lower mold 62 to be safely pressed together; the lower end of the power column 41 is provided with an inner rod 42 slidably connected to the power column 41, and the lower end surface of the inner rod 42 has an annular flange, and an annular air bag 43 is provided on the inner rod 42 between the annular flange and the bottom surface of the workbench 1, and a cylindrical air bag 44 is provided between the power column 41 and the inner rod 42. The cylindrical air bag 44 is connected to the telescopic part of the suction and sweeping assembly 8;

[0056] like Figure 5 As shown, the bottom surface of the movable platform 4 is also provided with a suction and sweeping assembly 8 for cleaning the upper mold 62, and the suction and sweeping assembly 8 is provided with a group, such as Figure 9As shown, the suction and sweeping assembly 8 includes an air supply portion for blowing the inner surface of the upper mold 61 and a telescopic portion for extending or retracting the air supply portion, the telescopic portion is composed of a longitudinal air rod 81 and a transverse air rod 82, one end of the longitudinal air rod 81 is connected to the bottom surface of the movable platform 4, and the other end is rotatably connected to the rear end of the transverse air rod 82 through a pneumatic rotating shaft 83, the pneumatic rotating shaft 83 is composed of a rotating shaft body 831, a rotating shaft sleeve 832, and a fan ring air bag 833 connected to the rotating shaft body 831 at one end and the rotating shaft sleeve 832 at the other end for driving the rotating shaft body 831 to rotate, the longitudinal air rod 81 and the transverse air rod 82 are connected to the rear end of the transverse air rod 82 through a pneumatic rotating shaft 83. And the fan-ring airbag 833 is connected to the first air pipe through a pressure valve, and the first air pipe is connected to the cylindrical airbag 44; the air supply part is composed of a negative pressure suction pipe 84 and a suction head 85 arranged at the front end of the negative pressure suction pipe 84, and the negative pressure suction pipe 84 is arranged at the front end of the transverse air rod 82, and in order to make it fit the bottom surface of the upper mold 61 more closely, the negative pressure suction pipe 84 can be connected to the transverse air rod 82 through a commercially available torsion spring shaft, and the negative pressure suction pipe 84 is connected to the second air pipe, and the second air pipe is connected to the annular airbag 43. It should be noted that a filter is provided at the connection between the negative pressure suction pipe 84 and the second air pipe to prevent debris from entering the annular airbag 43.

[0057] It is understandable that the various air bags and bag components mentioned above all use existing air bags or liquid bags. As shown in the figure, the gas rod mentioned above is a combination structure with hard ends and a gas bag in the middle. The hard parts at both ends are used to connect the components. The middle gas bag is used to make the longitudinal gas rod 81 and the transverse gas rod 82 extend and retract. The pressure valves are purchased from the market, and the thresholds of each pressure valve must meet the requirements for the above components to be triggered in sequence (see the following principle description for details). The structural parts not specially explained are all commercially available products, such as the first air pipe, the second air pipe, etc., which are all purchased from the market. If the extension margin is required, the length can be reserved or a commercially available retractable hose can be used.

[0058] The working principle of the above-mentioned corundum abrasive wheel pressing and forming equipment is as follows: the raw material is placed into the lower die 62, and then the hydraulic cylinder 5 is started. Under the drive of the hydraulic cylinder 5, the movable platform 4 moves downward, thereby moving the power column 41 downward. Under the cooperation of the power column 41, the arc section of the guide groove 71 of the rotating platform 7, and the guide block 72, the rotating platform 7 is rotated 180 degrees, so that the lower die 62 to be pressed on the rotating platform 7 is moved to just below the upper die 61. Then, under the cooperation of the power column 41, the vertical section of the guide groove 71 of the rotating platform 7, and the guide block 72, the upper die 61 and the lower die 62 are pressed. During this period, the annular airbag 43 is squeezed and the cylindrical airbag 44 is stretched.

[0059] When the pressing is completed, the hydraulic cylinder 5 drives the movable platform 4 to move upward, thereby moving the power column 41 upward. Under the cooperation of the power column 41 and the vertical section of the guide groove 71 of the rotating platform 7 and the guide block 72, the upper mold 61 and the lower mold 62 are separated. Then, under the cooperation of the power column 41 and the arc section of the guide groove 71 of the rotating platform 7 and the guide block 72, the rotating platform 7 is rotated and reset. During the rotation and reset of the rotating platform 7, the annular airbag 43 is stretched and the cylindrical airbag 44 is squeezed.

[0060] While the cylindrical airbag 44 is being squeezed, the longitudinal air rod 81 of the suction and sweeping assembly 8 is first straightened, and then after reaching the pressure valve threshold connected to the transverse air rod 82, the transverse air rod 82 is straightened, and then after reaching the pressure valve threshold connected to the fan-shaped airbag 833, the fan-shaped airbag 833 expands to deflect the rotating shaft body 831, so that the suction head 85 is in contact with the bottom surface of the upper mold 61. At the same time, the negative pressure suction force provided by the annular airbag 43 to the negative pressure suction pipe 84 is used to suck the debris on the bottom surface of the upper mold 61 into the negative pressure suction pipe 84, thereby completing the cleaning of the bottom surface of the upper mold 61.

[0061] Example 2: This example differs from Example 1 in that Figure 10-12 As shown, the movable platform 4 is provided with a guide sleeve 45 connected to the column 2 for sliding up and down, and a driving gear 46 is rotatably embedded in the guide sleeve 45. It can be understood that the empty groove of the guide sleeve 45 satisfies the rotation of the transmission rod 47 without affecting the rotation of the driving gear 46. The bottom surface of the upper mold 61 is rotatably connected to the upper mold base, and the bottom surface of the upper mold 61 is provided with a first bevel gear 63 for driving its rotation. A transmission rod 47 is also provided on the bottom surface of the movable platform 4, and one end of the transmission rod 47 is connected to the driving gear 46. The column 2 is connected to the upper mold 61, and the other end is provided with a second bevel gear 48 engaged with the first bevel gear 63 for transmission. The side of the column 2 is provided with a groove 21 for accommodating the driving gear 46, and the side of the groove 21 located in the upper middle part of the column 2 is provided with a rack 22 for engaging the driving gear 46 for transmission. The suction head 85 is bar-shaped, and the side of the suction head 85 in contact with the bottom surface of the upper mold 61 is provided with bristles. The bristles can be commercially available soft bristles, and hard bristles can also be selected according to the condition of the sticky material. There is no restriction on this.

[0062] The working principle of the above-mentioned corundum abrasive wheel pressing and molding equipment is: based on the working principle of Example 1, when the movable platform 4 moves to the position of the rack 22, the transmission rod 47 is rotated through the meshing transmission of the rack 22 and the driving gear 46, thereby rotating the bottom surface of the upper mold 61 through the meshing transmission of the first bevel gear 63 and the second bevel gear 48, thereby cooperating with the suction head 85 for sufficient cleaning.

[0063] Example 3: This example is different from Example 1 in that Figure 13As shown, a lubricant extrusion bag 9 for equipment lubrication is provided on the top surface of the movable platform 4, and an adjustable pressure plate is provided on the bottom surface of the top beam 3 corresponding to the position of the lubricant extrusion bag 9. The adjustable pressure plate includes a pressure plate body and a screw arranged on the pressure plate body, and the screw is threadedly connected to the screw hole on the top beam 3; the lubricant extrusion bag 9 is provided with a conduit for supplying lubricant between the movable platform and the column, between the rotating base and the workbench, and between the power column and the first through hole and the second through hole. It should be noted that the lubricant extrusion bag 9 adopts an existing liquid bag part, and the lubricant is commercially available.

[0064] The working principle of the above-mentioned corundum abrasive wheel pressing and forming equipment is: based on the working principle of Example 1, when the movable platform 4 moves to a position close to the top beam 3, the lubricant extrusion bag 9 is squeezed, and the lubricant is supplied through the conduit to the space between the movable platform and the column, between the rotating base and the workbench, and between the power column and the first through hole and the second through hole, thereby making the equipment maintenance easier.

[0065] Example 4: This example differs from Example 1 in that Figures 14-18 As shown, a demolding assembly for demolding the corundum abrasive grinding wheel is provided in the rotating pedestal 7 corresponding to the position of each lower mold 62, and a trigger mechanism for triggering the demolding assembly is provided on the top surface of the workbench 1 opposite to the upper mold 61. The demolding assembly includes an extrusion bag 73 provided in the rotating pedestal 7 and a telescopic bag 64 provided under the bottom surface of the lower mold 62. The bottom surface of the lower mold 62 is connected to the lower mold base in an up and down sliding manner, and the extrusion bag 73 is connected to the telescopic bag 64 through a pipeline; the trigger mechanism includes It includes a top block 11 arranged on the top surface of the workbench 1 opposite to the upper mold 61, and a slot 74 arranged on the rotating base 7 for the top block 11 to push the extrusion bag 73; the telescopic bag 64 is distributed in a ring shape under the bottom surface of the lower mold 62, and the bottom surface of the lower mold 62 is provided with a number of guide rods connected to the lower mold base for upward and downward sliding. It should be noted that the extrusion bag 73 and the telescopic bag 64 use existing air bags or liquid bags. There is no restriction on the filling medium, which can be selected as needed according to actual usage, such as hydraulic oil.

[0066] The working principle of the above-mentioned corundum abrasive wheel pressing and forming equipment is: based on the working principle of Example 1, when the rotating base 7 rotates, the top block 11 pushes the extrusion bag 73, thereby expanding the telescopic bag 64, thereby lifting the bottom surface of the lower mold 62 in the unloading area, so that the corundum abrasive wheel can be unloaded quickly.
