Description

Technical Field

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

[0002] A grinding wheel is an abrasive tool, usually round in shape. During the production of grinding wheels, ordinary abrasives are fixed together into a specific shape using a bonding agent. The three main components of a grinding wheel are abrasive, bonding agent, and pores. Grinding wheels are further classified according to the type of bonding agent used, such as ceramic-bonded grinding wheels, rubber-bonded grinding wheels, and resin-bonded grinding wheels.

[0003] In existing technologies, grinding wheels are made by mixing and pressing diamond and various additives. Since the raw materials used during pressing are all fine particles, they tend to stick to the inner wall of the pressing device. This means that the residual material from the previous pressing process can easily affect the product quality during the next pressing. The sticky material usually needs to be cleaned manually, which increases the workload of the workers and reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a grinding wheel forming device that eliminates the need for manual cleaning of the top of the lower and upper molds, reducing the labor intensity of workers and providing a good cleaning effect, thus avoiding any impact on the subsequent forming quality of the grinding wheel.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A grinding wheel forming apparatus, comprising

[0007] A workbench, wherein an assembly plate is fixedly installed on the rear top side of the workbench, and a controller is fixedly installed on the right top side of the workbench;

[0008] The lower mold is fixedly installed at the center of the top of the workbench, and an annular plate is slidably fitted inside the cavity of the lower mold.

[0009] The pressing mechanism is fixedly installed on the top of the assembly plate, and the bottom of the pressing mechanism is fixedly installed with an upper mold that matches the position of the lower mold.

[0010] The first cylinder is fixedly installed in the center of the rear side of the assembly plate.

Detailed Implementation

[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-5 As shown, this utility model provides a grinding wheel forming device, comprising:

[0027] Workbench 1, with an assembly plate 11 fixedly installed on the rear top side of workbench 1, and a controller 12 fixedly installed on the right top side of workbench 1;

[0028] The lower mold 2 is fixedly installed at the center of the top of the workbench 1. The cavity of the lower mold 2 is sealed and slidably fitted with an annular plate 21.

[0029] Pressing mechanism 3 is fixedly installed on the top of assembly plate 11. Pressing mechanism 3 has an upper mold 31 fixedly installed at the bottom, which matches the position of lower mold 2. Specifically, pressing mechanism 3 includes mounting platform 32, which is fixedly installed on the top of assembly plate 11. Two support columns 33 are mounted on the front side of the top of worktable 1 in a left-right distribution. The upper ends of the two support columns 33 are fixedly connected to the lower side of mounting platform 32. Mounting platform 32 has a mounting groove 331 on the top. The inner walls of the front and rear sides of mounting groove 331 are provided with sliding grooves 34. Sliding sliders 35 are slidably mounted inside the two sliding grooves 34. The two sliding sliders 35 are close to each other and are fixedly mounted on mounting block 36. A third cylinder 37 is fixedly mounted on the top left side of mounting block 36. The telescopic end of the third cylinder 37 passes through mounting block 36 and is fixedly connected to the top of upper mold 31. One of the sliding grooves 34 is provided with a drive component 38 for driving the sliding slider 35 to move left and right. The third cylinder 37 is electrically connected to controller 12.

[0030] When the grinding wheel needs to be pressed and shaped, the upper mold 31 and the lower mold 2 are aligned. The operator pours the grinding wheel forming material into the cavity of the lower mold 2. Then, the third cylinder 37 is activated, which drives the upper mold 31 to descend and extend into the cavity of the lower mold 2 to extrude and shape the grinding wheel. After extrusion and shaping, the operator controls the third cylinder 37 to move upward through the controller 12, ultimately maintaining a certain gap between the upper mold 2 and the lower mold 2. This gap is the same as the distance between the upper and lower sides of the two scrapers 42 and the two cleaning brushes 43. Then, the operator activates the second cylinder 44, causing the telescopic end of the second cylinder 44 to move upward. The moving annular plate 21 moves upward to eject the formed grinding wheel. When the annular plate 21 moves upward, it can also scrape out the residual material in the cavity of the lower mold 2. After the grinding wheel is ejected, the top of the annular plate 21 is flush with the top of the lower mold 2. After the worker removes the grinding wheel, the first cylinder 4 is started. The first cylinder 4 drives the connecting block 41 to move forward, which first drives the two scrapers 42 to clean the bottom of the upper mold 31 and the top 2 of the lower mold, sweeping off the residual material. Then the two cleaning brushes 43 perform a second cleaning to make the cleaning more thorough. After the cleaning is completed, the telescopic end of the first cylinder 4 is controlled to retract, and after the second cleaning is completed, the original state is restored, and the grinding wheel can be pressed for the second time.

[0031] The drive assembly 38 includes a lead screw 381, the left and right ends of which are rotatably connected to the inner walls of the left and right sides of the rear slide groove 34, respectively. The rear slider 35 is threadedly connected to the lead screw 381. A first motor 382 is fixedly installed on the rear left side of the mounting platform 32. The output shaft of the first motor 382 is driven by the lead screw 381. The first motor 382 is electrically connected to the controller 12. When it is necessary to use the drive assembly 38 to adjust the left and right movement of the mounting platform 32, the first motor 382 is started by the controller 12. The output shaft of the first motor 382 can rotate in both forward and reverse directions under the control of the controller 12. Then, through the threaded connection between the rear slider 35 and the lead screw 381, the slider 35 is driven to move left and right, and finally the left and right displacement of the mounting platform 32 is adjusted.

[0032] A fourth cylinder 361 is fixedly installed on the top right side of the mounting block 36. The telescopic end of the fourth cylinder 361 passes through the mounting block 36 and is fixedly installed on the mounting plate 362. A second motor 363 is fixedly installed at the bottom of the mounting plate 362. A turntable 364 is fixedly installed on the output shaft of the second motor 363. Several curved stirring rods 365 are assembled around the bottom of the turntable 364. Both the fourth cylinder 361 and the second motor 363 are electrically connected to the controller 12.

[0033] After the raw material is placed into the cavity of the lower mold 2, in the initial state, the mounting plate 362 is aligned with the lower mold 2. The operator starts the extension end of the fourth cylinder 362 to move downward, driving several curved stirring rods 365 to insert into the cavity of the lower mold 2. Then, the second motor 363 is controlled to rotate, and the output shaft of the second motor 363 drives the turntable 364 to rotate. The turntable 364 drives several curved stirring rods 365 to stir the raw material, so that the raw material can be more evenly distributed in the cavity of the lower mold 2, improving the pressing effect of the subsequent grinding wheel. After stirring is completed, the second motor 363 is turned off and the extension end of the fourth cylinder 362 is controlled to move upward. Then, the mounting block 36 is moved by the first motor 382, ​​so that the upper mold 31 is aligned with the lower mold 2, and the grinding wheel can be pressed.

[0034] The first cylinder 4 is fixedly installed in the center of the rear side of the assembly plate 11. The telescopic end of the first cylinder 4 passes through the assembly plate 11 and is fixedly installed with a connecting block 41. Scrapers 42 are fixedly installed on the front of the upper and lower sides of the connecting block 41, and cleaning brushes 43 are fixedly installed on the rear of the upper and lower sides of the connecting block 41.

[0035] The second cylinder 44 is fixedly installed at the bottom of the workbench 1. The telescopic end of the second cylinder 44 extends into the cavity of the lower mold 2 and is fixedly connected to the bottom of the annular plate 21. The first cylinder 4, the pressing mechanism 3 and the second cylinder 44 are all electrically connected to the controller 12.

[0036] A support plate 101 is fixedly installed on the top right side of the workbench 1, and the controller 12 is installed on the front side of the support plate 101; the support plate 101 is set so that the controller 12 has a certain height and tilt angle, which is convenient for use.

[0037] The device is used as follows:

[0038] When pressing the grinding wheel is required, the grinding wheel material is poured into the cavity of the lower mold 2. Then, the turntable 364 is controlled to move downward, causing several curved stirring rods 365 to insert into the cavity of the lower mold 2. The curved stirring rods 365 rotate and stir the material, making the material evenly distributed inside the cavity of the lower mold 2. After stirring, the turntable 364 is driven to move upward, controlling the upper mold 31 to align with the lower mold 2. During pressing, the lower mold 2 is controlled to fit into the cavity of the lower mold 2 for grinding wheel pressing. After pressing is completed, the telescopic end of the second cylinder 44 is controlled to move upward, causing the annular plate 21 to move upward. The grinding wheel extends out of the lower mold 2 cavity for easy handling by the operator. After handling, the extension end of the first cylinder 4 is controlled to extend one side, which in turn drives the two cleaning brushes 31 and the two scrapers 42 to clean the bottom of the upper mold 31, the top of the lower mold 2, and the top of the annular plate 21 to prevent material residue. After cleaning, the initial state is restored, and then the grinding wheel is pressed again. This operation method can clean the inside of the lower mold 2 cavity, resulting in better cleaning effect, improved product quality, and no need for manual operation by the operator, thus reducing the labor intensity of the operator.
