Description
Technical Field
[0001] The utility model relates to the field of glass production and processing, and more particularly to a graphite wheel, a rotating tool for the graphite wheel and a drilling tool. Background Art
[0002] During the production process of neutral borosilicate glass tubes, graphite wheels are usually used to position the glass tubes.
[0003] Changing the face of the graphite wheel is a frequent task, and the number of replacements required per month is as high as 20 times. In the prior art, when the face needs to be changed, the operator has always rotated the graphite wheel by hand using special thickened gloves.
[0004] However, rotating the graphite wheel by hand is very dangerous and has great potential safety hazards, because when performing this task, the tube drawing machine is always running, and at this time, there is not only a continuously drawn glass tube at high speed but also a rotating chain.
[0005] Therefore, a special tool that can eliminate this safety hazard is needed. This tool can replace the operator to complete the face-changing work of the graphite wheel by hand, and its structure is simple and the operation is convenient.
[0006] In addition, a drilling tool that can drill holes in the graphite wheel to combine with the special tool for face-changing is needed. Summary of the Utility Model
[0007] The purpose of the utility model is to provide a graphite wheel for producing glass tubes, a rotating tool for the graphite wheel and a drilling tool for the graphite wheel. The graphite wheel can fix the glass tube, and through the rotating tool, the graphite wheel can be safely face-changed, and through the drilling tool, a graphite wheel matching the rotating tool can be produced.
[0008] According to the first aspect of the utility model, a graphite wheel is provided. The graphite wheel is used to position the glass tube during the production of glass tubes. The graphite wheel includes a graphite wheel body in a cylindrical shape. A V-shaped groove is provided on the circumferential side of the graphite wheel body. The V-shaped groove is used to contact the glass tube when the graphite wheel is installed on a glass processing machine. On one end face of the graphite wheel body, there is a leg receiving hole for receiving a rotating tool. The rotating tool is used to rotate the graphite wheel circumferentially to change the contact position between the glass tube and the graphite wheel.
[0009] According to this first aspect, a graphite wheel that can be rotated by applying a rotating tool can be provided.
[0010] Preferably, the depth of the leg receiving hole does not extend axially beyond the V-shaped groove, thereby ensuring that the V-shaped groove can accurately position the glass tube.
[0011] According to a second aspect of the present utility model, there is provided a rotating tool for a graphite wheel according to the first aspect. The rotating tool includes: a handle that can be manipulated by an operator to rotate the graphite wheel; a leg attachment portion for attaching a leg; a handle connection mechanism for connecting the handle to the leg attachment portion and being disposed at a predetermined angle relative to the handle; and the leg that can be attached to the graphite wheel during use to drive the graphite wheel to rotate. The leg can be positioned in a corresponding leg receiving hole of the graphite wheel, and a torsional force can be applied to the handle to drive the leg to rotate and thus rotate the graphite wheel.
[0012] According to the rotating tool of this second aspect, the graphite wheel can be re-faced during production without endangering the safety of the operator.
[0013] In an advantageous manner, when the leg is assembled into the leg receiving hole on the graphite wheel, the length of the leg located in the leg receiving hole of the graphite wheel, that is, the depth of the leg receiving hole on the graphite wheel, does not exceed the V-shaped groove on the graphite wheel. According to this embodiment, the graphite wheel can accurately position the glass tube.
[0014] In an advantageous manner, the rotating tool has four legs, and the height of the legs is set such that when the rotating tool is applied to the graphite wheel, the leg attachment portion is located above the pressure plate of the graphite wheel without interfering with the pressure plate.
[0015] Preferably, the shape of the leg is circular, and the four legs are equidistantly arranged relative to the center of the leg attachment portion, and the distance between two relatively arranged legs is greater than the outer diameter of the pressure plate of the graphite wheel so as not to interfere with the pressure plate when using the rotating tool.
[0016] According to the above settings of the present utility model, the rotating tool can be attached to the graphite wheel during the production of glass to re-face the graphite wheel without interfering with the mating components of the graphite wheel.
[0017] In another advantageous manner, the size of the handle is set to be greater than the maximum distance between the legs. The distance between two relatively arranged legs is set to 88 mm, and the length of the legs is set to 55 mm. Such a size setting of the legs can avoid the edge of the gland for fixing the graphite wheel and does not interfere with the fixing components of the graphite wheel in the axial direction.
[0018] In another advantageous manner, the handle connection mechanism is arranged perpendicular to both the handle and the leg attachment portion.
[0019] Of course, it will be clear to those skilled in the art that the handle connection mechanism can be arranged not perpendicular to these two components, as long as the torsional force can be transmitted.
[0020] In another advantageous manner, the number of legs corresponds to the leg receiving holes on the graphite wheel, and the size and shape of the legs are arranged to correspond to the size and shape of the leg receiving holes on the graphite wheel, so as to rotate the graphite wheel when receiving the torsional force applied from the handle.
[0021] The third aspect of the present utility model relates to a drilling tool that can drill holes in a graphite wheel. When the graphite wheel is installed on a machine for producing glass tubes, a rotating tool can be assembled in the drilled holes to rotate the graphite wheel. The drilling tool includes two drilling dies, and both of the two drilling dies have positioning bosses on one side. When drilling holes in the graphite wheel, the graphite wheel can be positioned between the two drilling dies, wherein the corresponding positioning bosses of the two drilling dies are respectively combined into the central hole of the graphite wheel, and the shape and size of the positioning bosses are arranged to match the shape and size of the central hole of the graphite wheel. The two drilling dies also have threaded holes located at the center to fasten the graphite wheel between the two drilling dies through a screw rod.
[0022] According to the drilling tool described in the third aspect, it can be ensured that the positions and sizes of the holes drilled on each graphite wheel are consistent, thereby enabling the rotating tool to be matched with all graphite wheels.
[0023] In an advantageous manner, the two drilling dies have die holes located outside the positioning bosses. Through the die holes, leg receiving holes with corresponding shapes and sizes can be machined on the graphite wheel to engage with the legs of the rotating tool. Preferably, the drilling tool has 4 die holes, and these die holes are equidistantly arranged in the circumferential direction of the drilling die, and the distance between two opposite die holes is set to 88 mm. Since the outer diameter of the gland of the graphite wheel is basically the same, setting the hole pitch to 88 mm can avoid the edge of the gland. BRIEF DESCRIPTION OF THE DRAWINGS

In the specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present utility model with reference to the drawings is intended to explain the overall concept of the present utility model and should not be construed as a limitation of the utility model.
[0033] Figure 1 shows a schematic diagram of positioning a glass tube 60 using a graphite wheel 20, wherein the graphite wheel has a V-shaped groove on the side surface, and the glass tube 60 is positioned in the V-shaped groove. Figure 1 also shows pressure plates 50, 51 for positioning the graphite wheel 20 on a glass processing machine (not shown here).
[0034] Figure 2 shows a front view of a rotating tool 10 for a graphite wheel for producing glass tubes according to the present utility model. The rotating tool 10 includes: a handle 11 that can be manipulated by an operator to apply a torsional force; a leg attachment portion 12, on which a leg 14 is attached; a handle connection mechanism 13 that connects the handle 11 to the leg attachment portion 12; and a plurality of legs 14 that can be attached to Figure 2 the graphite wheel 20 shown during use to drive the graphite wheel 20 to rotate.
[0035] The handle connecting mechanism 13 is arranged perpendicular to the handle 11 and the leg attachment part 12. Of course, the handle connecting mechanism 13 can be arranged at other angles with respect to the handle 11 and the leg attachment part 12, as long as it can transmit the torsional force.
[0036] As Figure 3 shown, the graphite wheel 20 has a circular shape in the top view and includes leg receiving holes 21 uniformly arranged on one end face for receiving Figure 2 the multiple legs 14 shown in
[0037] In Figure 3 it is shown that there are 4 leg receiving holes 21, and the distance between two opposite leg receiving holes 21 is 88 mm. Therefore, in this embodiment, Figure 2 the number of legs 14 shown in
[0038] is 4, and the size and shape of the legs 14 are set to be able to correspond to the size and shape of the leg receiving holes 21 on the graphite wheel 20, so that the graphite wheel 20 can rotate when receiving the torsional force applied from the handle 11. Figure 3 Although not shown in
[0039] Figure 4 it is shown that Figure 2 a front view cross-sectional view of the rotating tool 10 shown in Figure 5 it is shown that Figure 2 a cross-sectional view of the rotating tool 10 shown in
[0040] As Figure 4 and Figure 5 shown, the legs 14 of the rotating tool 10 are inserted into the corresponding leg receiving holes 21 on the graphite wheel 20, where a torsional force can be applied to the handle 11 so that the legs 14 can drive the graphite wheel 20 to rotate to change the surface of the graphite wheel 20 in contact with the glass tube.
[0041] The size of the handle 11 is set to be greater than the maximum distance between the legs 14 and greater than the outer diameter of the graphite wheel 20 to facilitate the application of the torsional force. As Figure 1 、 Figure 4 and Figure 5 shown, the outer peripheral side of the graphite wheel 20 has a V-shaped groove 22, and this V-shaped groove 22 is used for Figure 1Contact the glass tube 60 shown in the figure to position the glass tube 60. When the leg 14 of the rotating tool 10 is assembled into the leg receiving hole 21 on the graphite wheel 20, the length of the leg 14 located in the leg receiving hole 21 on the graphite wheel 20, that is, the depth of the leg receiving hole 21 on the graphite wheel 20, does not exceed the V-shaped groove 22 on the graphite wheel 20, so as to avoid affecting the operation of the graphite wheel 20.
[0042] The rotating tool 10 has a total of four legs 14 for cooperating with the four leg receiving holes 21 in the graphite wheel 20. The height of the legs 14 is set such that when the rotating tool 10 is applied to the graphite wheel 20, the leg attachment portion 12 is located above the pressure plates 50, 51 ( Figure 1 shown in the figure) of the graphite wheel 20 without interfering with the pressure plates 50, 51.
[0043] The shape of each leg 14 is circular, and the distance between two oppositely arranged legs 14 is greater than the outer diameter of the pressure plates 50, 51 of the graphite wheel 20, so as not to interfere with the pressure plates 50, 51 when using the rotating tool 10.
[0044] As Figure 2 shown, the inner distance between two oppositely arranged legs 14 is set to 82 mm, and the diameter of the legs 14 is 6 mm, so that the distribution of the legs 14 is exactly the same as the distribution of the leg receiving holes 21 on the graphite wheel 20. In addition, the length of the legs 14 is set to 55 mm so as not to interfere with other devices on the graphite wheel 20.
[0045] The maximum lateral dimension of the handle 11 is 150 mm, and the distance between the handle 11 and the leg attachment portion 12 is about 200 mm.
[0046] Install the graphite wheel 20 on the glass tube processing machine to fix the glass tube 60. When it is necessary to change the face of the graphite wheel 20, insert the legs 14 of the rotating tool 10 into the leg receiving holes 21 of the graphite wheel 20, and use the torsional force applied on the handle 11 to rotate the graphite wheel 20, so as to change the contact position between the graphite wheel 20 and the glass tube 60.

The shapes and sizes of the positioning bosses 31, 41 are set to be able to match the shapes and sizes of the central hole 23 of the graphite wheel 20. Additionally, the two drilling dies 30, 40 respectively further have threaded holes 32, 42 located at their centers, so as to fasten the graphite wheel 20 between these two drilling dies 30, 40 through the screw 43 shown in Figure 7 .
[0049] Both of the two drilling dies 30, 40 have die holes (not shown in Figure 6 and Figure 7 ) located outside the positioning bosses 31, 41. Through these die holes, leg receiving holes 21 with corresponding shapes and sizes can be machined on the graphite wheel 20 to engage with the respective legs 14 of the rotating tool 10.
[0050] As shown in the graphite wheel 20 according to Figure 3 , both of the two drilling dies 30, 40 also respectively have 4 corresponding die holes, these die holes are equidistantly arranged in the circumferential direction of the drilling dies 30, 40, and the distance between two opposite die holes is also correspondingly set to 88 mm.
[0051] The following describes the processing method of the leg receiving holes on the graphite wheel.
[0052] First, the undrilled graphite wheel 20 is clamped between the two drilling dies 30, 40, such that the central hole 23 of the graphite wheel 20 (as shown in Figure 4 and Figure 5 ) is sleeved between the corresponding positioning bosses 31, 41 of the two drilling dies 30, 40.
[0053] Then, the screw 43 (shown in Figure 7 ) is screwed into the central threaded holes 32, 43 of the two drilling dies 30, 40 to fasten the graphite wheel 20.
[0054] Finally, four leg receiving holes 21 on the graphite wheel 20 are machined on the drilling tool.
[0055] The component dimensions and shapes in the embodiments are only exemplary, and those skilled in the art can think of setting them to other dimensions or shapes.
