Description

Technical Field

[0001] The present application relates to the technical field of isostatic graphite, and in particular to a method for grinding cylindrical isostatic graphite. Background Art

[0002] During the grinding process of isostatic graphite, dust is generated. Most existing dust removal methods use suction to extract the dust, but this method still generates a certain amount of dust. Summary of the invention

[0003] In view of the shortcomings of the prior art, one of the purposes of the present application is to provide a cylindrical isostatic graphite grinding method, which has the advantage of reducing dust dispersion.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] A method for grinding cylindrical isostatic graphite adopts a grinding device, which comprises a grinding cylinder, wherein a grinding part and a spray part are arranged in the grinding cylinder, wherein the spray part is located above the grinding part, and a driving part for driving the grinding part to approach or move away from the isostatic graphite is also arranged in the grinding cylinder, wherein the grinding device also comprises a grinding table, wherein the grinding table is used to support the isostatic graphite and drive the isostatic graphite to rotate; and further comprises the following steps: a placing step, wherein the isostatic graphite is placed on the grinding table, a spraying step, wherein the spray part sprays water mist to increase the humidity in the grinding cylinder, and a grinding step, wherein the driving part drives the grinding part to move so that the grinding part and the isostatic graphite are in contact, wherein the grinding table drives the isostatic graphite to rotate, and the spray part sprays water mist.

[0006] By adopting the above technical solution, during use, the dust can be concentrated through the setting of the grinding cylinder, and water mist is sprayed through the spray part before and during grinding, so the dust is easily combined with the water mist and then settled, further reducing the probability of dust dispersion.

[0007] In a preferred example, the present application can be further configured as follows: the grinding device also includes a lifting assembly, the lifting assembly includes a lifting ring and a lifting part, the lifting part is used to drive the grinding cylinder to lift and lower, the lifting part is used to drive the lifting ring to lift and lower, the lifting ring is arranged in the grinding cylinder and is slidably connected to the grinding cylinder, the grinding part and the spray part are both arranged on the lifting ring, the lifting ring is also provided with an air outlet, the air outlet is arranged above the spray part, and the grinding cylinder is also provided with a through hole, and the through hole is located below the air outlet.

[0008] By adopting the above technical solution, the existence of the air outlet enables the water mist sprayed by the spray part to move toward the polishing part under the action of the gas during the polishing process, thereby achieving a better dust settling effect.

[0009] In a preferred example, the present application can be further configured as follows: in the spraying step, the lifting assembly drives the spraying part to move to the bottom of the isostatic graphite, and drives the spraying assembly to move upward.

[0010] By adopting the above technical solution, during the spraying process, the spray moves upward from the bottom of the isostatic graphite, so that the wetting effect of the surface of the isostatic graphite is better, thereby further reducing the probability of dust floating during the grinding process.

[0011] In a preferred example, the present application can be further configured as follows: the driving member includes an airbag, the polishing member is installed on the airbag, the airbag is connected to the air outlet through a tube, and the airbag expands under the action of an external air source.

[0012] By adopting the above technical solution, when the polishing workpiece needs to come into contact with the isostatic graphite, the airbag expands under the action of pressure, thereby coming into contact with the isostatic graphite. At the same time, during the polishing process, excess gas can be connected from the air outlet, thereby ensuring the pressure inside the airbag is stable.

[0013] In a preferred example, the present application can be further configured as follows: in the grinding step, the lifting assembly drives the grinding piece to move above the isostatic graphite, and then the air bag is pressurized so that the grinding piece and the isostatic graphite are in contact, and the gas is discharged from the air outlet and in contact with the isostatic graphite.

[0014] By adopting the above technical solution, the gas causes the airbag to expand and contact with the isostatic graphite. At the same time, during this process, excess gas is discharged from the air outlet, thereby guiding the water mist and removing the dust attached to the isostatic graphite.

[0015] In a preferred example, the present application can be further configured as follows: it also includes a verification step, in which the humidity of the gas discharged from the through hole is verified. If it does not meet the standard value, the amount of dust carried by the gas discharged from the through hole is judged. If it reaches the standard value, an abnormal humidity alarm is issued.

[0016] By adopting the above technical solution, that is, by judging the humidity and the amount of dust, it can be concluded whether the spraying part is working normally. At the same time, the existence of the through hole can play a role in pressure relief, thereby reducing the probability of dust leakage from other connections. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1 , a cylindrical isostatic graphite grinding method disclosed in the present application, using a grinding device, the grinding device includes a grinding cylinder 2 and a lifting assembly, a grinding part 5 and a spray part 6 are arranged in the grinding cylinder 2, the spray part 6 is located above the grinding part 5, and a driving part 4 for driving the grinding part 5 to approach or move away from the isostatic graphite is also arranged in the grinding cylinder 2, and the grinding device also includes a grinding table 1, which is used to support the isostatic graphite and drive the isostatic graphite to rotate. A three-jaw chuck 11 is arranged on the grinding table 1, and the opening of the grinding cylinder 2 is arranged upward, and the grinding cylinder 2 moves under the action of a driving unit. In this embodiment, the driving unit can be a manipulator, a linear module or a cylinder, etc.

[0021] The grinding device also includes a lifting assembly, which includes a lifting ring 3 and a lifting member. The lifting ring 3 and the grinding cylinder 2 are connected in a vertical sliding manner through a slide rail. In this embodiment, the lifting member is a motor, which drives the lifting ring 3 to rise and fall by winding and unwinding the cable. In other embodiments, it can also be a manipulator, a linear module or a cylinder.

[0022] The driving member 4 includes an airbag, which is made of rubber. The polishing member 5 includes a polishing layer and a connecting layer. The connecting layer is made of a flexible material (such as leather, aramid fiber cloth, etc., which are flexible but have poor stretchability). The polishing layer is sandpaper. Adhesion to the connecting layer. A pressure relief pipe is also provided on the airbag, which is connected to the air outlet 7 provided on the lifting ring 3. A pressure relief valve is provided at the air outlet 7. The air outlet 7 is located above the spray member 6, and the spray member 6 is located above the polishing member 5. The spray member 6 is an atomizing nozzle.

[0023] The process also includes the following steps: a placing step, placing the isostatic graphite on the grinding table 1, so that the isostatic graphite is clamped by the three-turn chuck; a spraying step, the lifting assembly drives the spraying part 6 to move to the bottom of the isostatic graphite, and drives the spraying assembly to move upward, the spraying part 6 sprays water mist to increase the humidity in the grinding cylinder 2; a grinding step, the lifting assembly drives the grinding part 5 to move to the top of the isostatic graphite, and then the air bag is pressurized so that the grinding part 5 and the isostatic graphite are in contact. At this time, under the action of the isostatic graphite, the gas is discharged from the air outlet 7 and contacts with the isostatic graphite. The isostatic graphite contacts the isostatic graphite (that is, when there is no isostatic graphite, the gas will not be discharged from the air outlet 7. The grinding piece 5 contacts the isostatic graphite during the expansion process, so that the expansion space becomes smaller, and the gas is discharged from the air outlet 7. In use, when there is no isostatic graphite, the pressure can be continuously increased until the gas is discharged from the air outlet). The gas is discharged from the air outlet 7 and contacts the isostatic graphite. Then the three-jaw chuck 11 drives the isostatic graphite to rotate, and the spray assembly sprays water mist. Verification step, verify the humidity of the gas discharged from the through hole 21. If it does not meet the standard value, judge the amount of dust carried by the gas discharged from the through hole 21. If it reaches the standard value, an abnormal humidity alarm is issued. When the speed of the gas discharged from the through hole 21 is greater than the corresponding value A or less than the corresponding value B, a prompt is given. That is, in production, when grinding isostatic graphite of specification A, the preset gas pressure is A. When the diameter of the isostatic graphite is larger than the standard diameter, the gas discharge volume increases, and when the diameter of the isostatic graphite is smaller than the standard diameter, the gas discharge volume decreases. Therefore, the specifications of the isostatic graphite can be judged, thereby making the specifications of the isostatic graphite more uniform.

[0024] The implementation principle of this embodiment is: by providing the grinding cylinder 2, the spraying member 6 and the grinding member 5, the probability of dust escaping to the environment during the grinding process is reduced.

[0025] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
