Description

Technical Field

[0001] The invention relates to the technical field of grinding wheels, in particular to a manufacturing device for cutting grinding wheels in the foundry industry. Background Art

[0002] Grinding wheels, also known as bonded abrasives, are made by bonding ordinary abrasives into a specific shape (mostly round with a central hole) with a certain strength. They are generally composed of abrasives, a bond, and pores, which are often referred to as the three elements of a bonded abrasive.

[0003] The existing grinding wheels used in the casting industry require high hardness, and the existing grinding wheels are usually made of diamond as an abrasive. After long-term use, the grinding wheels are prone to wear, which affects the cutting effect. In severe cases, the grinding wheels will crack and cause injuries from grinding wheel fragments. In addition, during production, the existing grinding wheels are dried naturally in a natural environment or artificially dried by heating. Drying in a natural environment has a slow drying efficiency for the grinding wheels and requires the grinding wheels to be stacked, which easily causes uneven drying of the grinding wheels and affects the quality of the grinding wheels. Drying by heating requires manual stacking of the grinding wheels in a drying room for drying, which increases labor and is inefficient. Summary of the Invention

[0077] In order to dry the grinding wheel blank, the drying device also includes a drying shell 8, the inner wall of the drying shell 8 is fixedly mounted on the outer surface of the annular conveying guide rail 5, and a fan 81 is fixedly mounted on the upper surface of the drying shell 8. The air outlet end of the fan 81 is fixedly mounted on the outer surface of the air duct 82 through a connecting pipe. The outer surface of the air duct 82 is fixedly mounted on the inner wall of the drying shell 8, and an electric heating wire 83 is fixedly mounted on the inner wall of one side of the drying shell 8.

[0078] Working principle: The grinding wheel blank to be dried is placed in the material rack 12, the pallet conveyor line 11 is started, and the material rack 12 is transported. After reaching the set position, the telescopic hydraulic cylinder 23 on the mobile platform 2 is started, driving the clamping jaws 41 to be located directly above the grinding wheel on the material rack 12. The mobile platform 2 controls the telescopic hydraulic cylinder 23 to descend, so that each set of clamping jaws 41 can be located on both sides of each grinding wheel. The clamping motor 42 on the adjustable distance frame 3 is controlled to start. The clamping motor 42 drives the transmission rod 43 to rotate through the cooperation of the belt and the pulley. The transmission rod 43 drives the double-headed screw 4 to rotate through the bevel gear group, so that the clamping jaws 41 approach the grinding wheel and clamp the grinding wheel.

[0079] After the clamping is completed, the mobile platform 2 drives the grinding wheel to rise, so that the grinding wheel leaves the material rack 12, the telescopic hydraulic cylinder 23 retracts, and the adjusting motor 22 in the adjusting housing 21 is started to drive the telescopic hydraulic cylinder 23 to rotate ninety degrees, so that the grinding wheel perpendicular to the ground can be parallel to the ground, keeping the center hole of the grinding wheel and the center line of the support sleeve 51 on the upper annular conveying guide rail 5 on the same horizontal line, the distance adjusting motor 31 on the distance adjusting frame 3 is started, driving the rotation of the distance adjusting screw rod 32, and the distance adjusting screw rod 32 drives the two fixed frames 33 threadedly connected thereto to move within the distance adjusting frame 3, and the movable fixed frame 33 pulls the remaining movable fixed frame 33 installed therewith through the scissors frame component 34 to move, and the movement of the fixed frame 33 drives the clamping claws 41 to adjust the spacing, so that the spacing between the grinding wheels is equal to the spacing between the support bars 55, the upper grinding wheel moves upward, and the lower grinding wheel moves downward, completing the spacing adjustment;

[0080] The movable platform 2 drives the distance adjusting frame 3 to rise, so that the grinding wheel can be sleeved on the support sleeve 51, and the upper end grinding wheel can be located above the support bar 55. The movable motor 61 is started, and the driving gear 56 is driven to rotate through the gear. The driving gear 56 drives the driving rod 52 in the support sleeve 51 to rotate, thereby driving the rotation of the driving disk 53. The driving disk 53 can drive the support bar 55 in the limiting groove body 54 to move outward of the support sleeve 51 through the arc groove to perform the expansion action. The support bar 55 can contact the lower surface of the grinding wheel to support the grinding wheel. Under the drive of the clamping motor 42, the double-headed screw 4 drives the clamping claw 41 to move outward to release the clamping of the grinding wheel. The grinding wheel is placed on the support bar 55, and the movable platform 2 drives the telescopic hydraulic cylinder 23 to descend, so that the distance adjusting frame 3 leaves the support sleeve 51.

[0081] The annular conveying guide rail 5 starts, drives the support sleeve 51 to move, and the insertion strip 57 on the support sleeve 51 leaves the pressing block 58 and is reset under the action of the torsion spring. One end of the insertion strip 57 is inserted into the tooth groove of the driving gear 56 to limit the driving gear 56, and the moving hydraulic cylinder 6 drives the moving motor 61 to rise. As the support sleeve 51 moves, the gear ring 71 on the support sleeve 51 rotates on the U-shaped rack 7, driving the support sleeve 51 to rotate, so that the rear support sleeve 51 enters the corresponding position. The insertion strip 57 on the rear support sleeve 51 is pressed after passing through the pressing block 58, and the insertion strip 57 leaves the fixation on the driving gear 56, and the moving hydraulic cylinder 6 pushes the gear on the moving motor 61 to mesh with the driving gear 56, so as to drive the rotation of the driving rod 52. The steering motor drives the spacing frame 3 to flip, so that the grinding wheel at the lower end can be located at the upper end, and the grinding wheel is placed on another support sleeve 51;

[0082] The support sleeve 51 drives the grinding wheel into the drying shell 8, and the air is sucked by the fan 81 and then transported into the air duct 82. After the electric heating wire 83 is turned on, hot air is blown to dry the grinding wheel.
