Description

Technical Field

[0001] This utility model relates to the field of hard disk material preparation technology, and in particular to a glass profile processing equipment and a glass profile. Background Technology

[0002] Initially, aluminum was used as the substrate material for hard disk drives (HDDs) and was used for a long time in mainstream HDDs. Aluminum substrates have the advantages of relatively low cost, ease of processing (stamping), and good mechanical strength (not easy to break). However, they also have several shortcomings, such as insufficient surface flatness, poor thermal stability, insufficient hardness, and defects in microstructure. Therefore, in order to overcome the shortcomings of aluminum substrates, people tried soda-lime glass and later replaced aluminum with aluminosilicate glass (AS system glass) as the hard disk substrate.

[0003] By adjusting the composition, particularly by increasing the Al2O3 content, ion-exchange chemically strengthened AS system glasses significantly improve the strength, hardness, and chemical stability of the glass substrate, while reducing the coefficient of thermal expansion. However, ion-exchange chemically strengthened AS system glasses cannot meet the required high-temperature operating conditions. Therefore, there is still a need in the field to develop glass profiles with superior performance to meet the growing demands.

[0004] After developing glass materials with better performance, new problems arose. In the previous glass substrate processing method, solid glass rods were usually made directly, then the solid glass rods were cut into glass discs, and then the glass discs were cut to obtain ring-shaped glass blanks. Finally, the glass blanks were processed.

[0005] However, because the cut glass sheets are quite thin, generally less than 0.7mm, and sometimes even less than 0.4mm, conventional cutting methods make it difficult to process disc-shaped glass sheets into hollow glass rings. At the same time, since each disc-shaped glass sheet needs to be processed during cutting, this greatly increases the processing time and leads to low processing efficiency. Furthermore, existing processing methods are very likely to damage the thin glass sheets when cutting and separating the ring core, increasing production costs. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to propose a glass profile processing equipment. By setting up a fluid pipeline and the pull-down channel, the prepared glass profile has a hollow structure, which solves the problems of low processing efficiency and easy material damage in subsequent processing of solid glass rods.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A glass profile processing equipment includes a furnace chamber and a forming device, wherein the forming device is connected to the furnace chamber, and the forming device includes: A first molded part has at least one pull-down channel; the pull-down channel is disposed at the bottom of the furnace chamber and communicates with the furnace chamber. The second molding component includes at least one fluid conduit, which is coaxial with the pull-down channel. The fluid conduit is inserted into the furnace chamber and rotatably connected to the top of the furnace chamber. The bottom of the fluid conduit is located in the pull-down channel, and the fluid in the fluid conduit is directed towards the pull-down channel to form the hollow portion of the glass profile.

[0008] Preferably, the ratio of the outer diameter of the fluid pipe to the inner diameter of the pull-down channel is 7:1 to 2:1.

[0009] Preferably, the drop-down channel includes: A pull-down hole is provided at the bottom of the furnace chamber; A conical section, which is fixed to the bottom of the furnace chamber and communicates with the pull-down hole.

[0010] Preferably, the pull-down channel further includes an arc-shaped segment, which communicates with the outlet portion of the pull-down hole.

[0011] Preferably, the diameter of the pull-down hole is greater than 40mm.

[0012] Furthermore, it also includes a guiding device, which is disposed in the discharge direction of the molding device to guide the discharge of the molding device.

[0013] Preferably, the bottom of the fluid pipe is provided with an expanded flared opening, which is located within an arc-shaped section.

[0014] This utility model also claims protection for a glass profile, which is processed by the glass profile processing equipment described above, and the glass profile is in the shape of a hollow rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) In the fluid pipe and pull-down channel set up in this utility model, when glass profile is prepared, the glass liquid flows down the pull-down port of the pull-down channel, passes through the conical section, and finally reaches the arc section. When it reaches the arc section, the fluid channel rotates, which centrifugally rotates the glass liquid. The glass liquid swirls and sprays onto the inner wall of the arc section. High-pressure gas is introduced from the air inlet of the fluid channel at the top of the furnace chamber to the horn mouth and sprays out, blowing the glass liquid onto the inner wall of the arc section to form a hollow rod-shaped glass liquid. Finally, it is formed and flows out from the outlet of the arc section. The material is guided out by the guiding device to prepare the hollow glass profile with uniform wall thickness, which facilitates the subsequent processing of glass sheets and improves the production efficiency and product qualification rate of the product.

[0016] (2) The conical section of this utility model has a liquid outlet that is large to small, which makes the glass liquid flow out more smoothly, avoids blockage or uneven flow, and improves the finished product qualification rate of glass profiles. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 like Figure 1 A glass profile processing equipment includes a furnace chamber 1 and a forming device, wherein the forming device is connected to the furnace chamber 1, and the forming device includes: A first molded part has at least one pull-down channel 4; the pull-down channel 4 is disposed at the bottom of the furnace chamber 1 and communicates with the furnace chamber 1. The second molding component includes at least one fluid conduit 3, which is coaxial with the pull-down channel 4. The fluid conduit 3 is inserted into the furnace chamber 1 and rotatably connected to the top of the furnace chamber 1. The bottom of the fluid conduit 3 is located in the pull-down channel 4, and the fluid in the fluid conduit 3 is directed towards the pull-down channel 4 to form the hollow portion of the glass profile.

[0021] The furnace chamber 1 is equipped with a liquid inlet for the entry of molten glass, and the pull-down channel 4 facilitates the outflow of molten glass. The air inlet at the top of the fluid pipe 3 can be connected to a high-pressure gas compressor to introduce high-pressure air, thereby blowing the molten glass in the pull-down channel 4 to facilitate the forming of the hollow glass rod. During blowing, the fluid pipe 3 rotates, causing the molten glass to swirl at the bottom of the fluid pipe 3, maintaining the uniformity of the flow of the molten glass. Specifically, the rotation of the fluid pipe 3 requires a rotatable connection between the fluid pipe 3 and the top wall of the furnace chamber 1 through a bearing. A motor is installed at the top of the furnace chamber 1, with a gear fixed on the motor and another gear fixed at the top of the fluid pipe 3. The fixed gear on the motor meshes with the fixed gear on the fluid pipe, driving the fluid pipe 3 to rotate. Other methods in the prior art can also be used to achieve the rotation of the fluid pipe 3 and the introduction of high-pressure gas, which are not limited here.

[0022] It should be noted that the furnace chamber is also equipped with heating components. The heating device can be an electric heating coil installed at the bottom of the furnace chamber 1. The heating temperature can be monitored and controlled by the electric heating coil controller to prevent the glass melt from solidifying due to a drop in temperature after entering. It should also be noted that the heating device can be other common existing technologies, which are not limited here.

[0023] In this embodiment, the ratio of the outer diameter of the fluid pipe 3 to the inner diameter of the pull-down channel 4 is 7:1 to 2:1.

[0024] The ratio of the outer diameter of the fluid pipe 3 to the inner diameter of the pull-down channel 4, combined with the configuration of the fluid pipe 3, can limit the inner and outer diameters of the glass rod, thus producing a size that better meets the requirements of hard disk materials.

[0025] In this embodiment, the pull-down channel 4 includes: Pull-down hole 41, wherein the pull-down hole 41 is formed at the bottom of the furnace chamber 1; The tapered section 42 is fixed to the bottom of the furnace chamber 1 and communicates with the pull-down hole 41.

[0026] The pull-down hole 41 is the outlet of the molten glass in the furnace chamber 1, flowing towards the conical section 42. The flow opening of the conical section 42 decreases from large to small, ensuring that the molten glass is fully discharged when it flows out, thus avoiding the formation of pores.

[0027] In this embodiment, the pull-down channel 4 further includes an arc-shaped segment 43, which is connected to the outlet of the pull-down hole 41.

[0028] The curved section 43, in conjunction with the flared mouth 31, allows the molten glass to flow downwards along the inner wall of the curved section 43 under the influence of high-pressure gas and the rotation of the fluid pipe 3, further ensuring the uniform thickness of the glass rod.

[0029] In this embodiment, the diameter of the pull-down hole 41 is greater than 40mm.

[0030] In this embodiment, a guiding device 6 is also included, which is disposed in the discharge direction of the molding device and is used to guide the discharge of the molding device.

[0031] The guiding device 6 is used to transport the glass profile 5 and can guide natural cooling. The guiding device can be a belt conveyor or other conveyors in the prior art. The belt material of the belt conveyor needs to be selected as a high temperature resistant material. At the end of the conveying, it can also be connected to the cooling system in the prior art for air cooling or water cooling. After cooling, the material is discharged by cutting.

[0032] In this embodiment, the bottom of the fluid pipe 3 is provided with an expanded flared opening 31, which is located within the arc-shaped section 43.

[0033] Example 2 A glass profile, which is processed by the glass profile processing equipment described in Example 1, wherein the glass profile is in the shape of a hollow rod.

[0034] Hollow rod-shaped glass profiles eliminate the need for reprocessing each glass sheet, reducing processing time, improving processing efficiency, lowering the risk of glass sheet damage, and increasing product qualification rate.

[0035] The processing principle of a glass profile processing equipment according to this utility model is as follows: After heating the molten glass to a temperature that will not cool down after entering the furnace chamber 1, the motor is turned on to drive the fluid pipe 3 to rotate and high-pressure gas is introduced into the fluid pipe 3. The molten glass enters the furnace chamber 1 through the inlet and flows to the pull-down channel 4 set at the bottom of the furnace chamber 1. It first reaches the pull-down hole 41, then passes through the conical section 42. The flow opening of the conical section 42 decreases from large to small to ensure that the molten glass is fully discharged. Finally, it reaches the arc section 43. When it reaches the arc section and flows to the funnel mouth 31, the high-speed rotating fluid pipe 3 and the blowing of high-pressure gas form a swirling flow of molten glass that splashes onto the inner wall of the arc section 43, which is hollow. Finally, it flows out of the arc section 43 to obtain the glass profile 5. It is then transported and cooled by the guiding device and finally cut to complete the production of the glass profile 5.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
