Fig. 1 is a schematic view of an edge roller 010 according to an embodiment of the present invention; FIG. 2 is an enlarged schematic view of detail II of FIG. 1; fig. 3 is an enlarged view of a portion III of fig. 1. Referring to fig. 1 to 3, the present embodiment provides an edge roller assembly 100 and an edge roller 010 with the edge roller assembly 100. As shown in fig. 1, the edge roller 010 includes two edge roller assemblies 100 (only one is shown in the drawing) and an apparatus main body 011 that drives the edge roller assemblies 100 to rotate. The free end parts of the edge-drawing shaft assemblies 100 penetrate through the furnace wall 200 and extend into a furnace body for glass cooling forming, the two edge-drawing shaft assemblies 100 can clamp glass liquid flowing down from overflow bricks, the thickness of the glass liquid flowing down is controlled, and meanwhile, the glass liquid is cooled through cooling gas circulating in the edge-drawing shaft assemblies 100, so that a formed glass plate is obtained.
It is understood that the apparatus main body 011 of the edge roller 010 can include a driving assembly (not shown) for driving the edge roller assembly 100 to rotate, and can further include a gas source (not shown) for supplying gas into the edge roller assembly 100, and of course, the gas source can be independently provided outside the edge roller 010.
The edge-pulling shaft assembly 100 comprises a main shaft 110, an air duct 130 arranged in the main shaft 110, and a roller 120 arranged at the free end of the main shaft 110. As shown in fig. 2, the main shaft 110 has an inner cavity extending along the main shaft 110 and penetrating both ends of the main shaft 110, the air duct 130 is coaxially disposed within the main shaft 110, and a flow passage 114 is formed between an outer wall of the air duct 130 and an inner wall of the main shaft 110 so as to pass the cooling gas when the cooling gas flows back. The roller 120 also has an internal cavity and is in communication with the internal cavity of the main shaft 110 and the internal cavity of the air duct 130. The outer circumferential surface 121 of the roller 120 is used to contact and cool the molten glass. In this embodiment, the roller 120 has a cylindrical shape with one end closed, and the other end thereof communicates with the main shaft 110 and the air duct 130. The peripheral side of the roller 120 is adapted to contact the molten glass and absorb heat from the molten glass. In use, the cooling gas flows from within the air duct 130 into the interior cavity of the roller 120 and then further back out of the flow passage 114 between the air duct 130 and the main shaft 110. In this process, the gas removes a large amount of heat, thereby cooling the molten glass.
As shown in fig. 3, in the present embodiment, the main shaft 110 is provided with at least one exhaust hole 112 communicating with an inner cavity thereof, and a flow blocking portion 132 is provided around the outer side of the air duct 130. The exhaust hole 112 is located between the flow blocking portion 132 and the roller 120 in the axial direction of the main shaft 110. When the cooling gas after absorbing heat flows back through the flow passage 114, the flow blocking portion 132 forces the gas in the flow passage 114 to be discharged out of the main shaft 110 through the discharge hole 112. Of course, the location of the exhaust port 112 should be outside the furnace body when in use.
In this embodiment, the flow blocking portion 132 is a boss circumferentially disposed around the air pipe 130, the air pipe 130 is disposed coaxially with the main shaft 110, the size of the flow blocking portion 132 may be designed according to the inner diameter of the main shaft 110, and optionally, the overall outer diameter of the flow blocking portion 132 may be 1mm smaller than the inner diameter of the main shaft 110.
The beneficial effects of providing the exhaust hole 112 and the flow blocking part 132 are that: because the cooling gas can be through the continuous direction transmission to equipment main part 011 place of edge-pulling axle in stove heat, and mechanical parts such as sealing member, gear, bearing exist inside equipment main part 011, if do not reduce the heat that the air current brought, the heat of so continuously deriving causes equipment lubrication failure, can aggravate ageing, the degree of wear of spare part, restricts the life of edge-pulling machine 010. The arrangement of the exhaust hole 112 and the flow blocking portion 132 of the present embodiment can exhaust the gas from the main shaft 110 in advance, and prevent the high-temperature gas flowing back from further approaching the apparatus main body 011, thereby preventing the apparatus main body 011 from being subjected to thermal shock. The service life of the device can be increased.
Fig. 4 is a schematic view illustrating the assembly of the spindle 110 and the roller 120 according to an embodiment of the present invention. Referring to fig. 3 and 4, in this embodiment, the main shaft 110 is provided with a plurality of air outlet holes 112, for example, 4 air outlet holes. A plurality of exhaust holes 112 are circumferentially provided at intervals on a sidewall of the main shaft 110. The total exhaust area of the plurality of exhaust holes 112 is larger than the cross section of the inner cavity of the air duct 130 in view of better exhaust under thermal expansion of the gas. Of course, in alternative embodiments of the present invention, the plurality of exhaust holes 112 on the main shaft 110 may be axially spaced, as shown in fig. 5.
As the main shaft and a part of the roller need to work in the environment of 1000-1080 ℃ for a long time, the phenomena of main shaft bending and roller abrasion can exist during long-term use, and the stable production of products is seriously restricted. For this reason, the main shaft 110 and the roller 120 of the present embodiment are made of hastelloy (e.g., HAYNES230), and are welded to each other. The hastelloy is a nickel-chromium-tungsten-molybdenum alloy, and has excellent high-temperature strength, oxidation resistance, ultra-long-time thermal stability and good processability. The hastelloy has outstanding oxidation resistance and very good long-term thermal stability in a high-temperature environment of 1149 ℃ for a long time. The hastelloy has excellent machining performance, lower thermal expansion characteristic and good forming and welding performance, has excellent oxidation resistance in air and combustion gas oxidation environments, can continuously work for a long time at the high temperature of 1149 ℃, and completely meets the use conditions of the main shaft 110 and the roller 120.
After the main shaft 110 and the roller 120 are assembled successfully, sealing welding is needed, high-pressure air of 0.5MPa is introduced into the main shaft 110 after welding is completed, airtightness inspection is conducted, and temperature field changes in the forming furnace caused by leakage when cooling air is introduced into the shaft are prevented. Furthermore, after the assembly of the main shaft 110 and the welding of the roller 120 are completed, the coaxiality is required to be less than or equal to 0.20 mm.
As shown in fig. 1, the apparatus main body 011 drives two main shafts 110 to pass through a forming furnace wall 200 and enter a high temperature environment in the forming furnace, the two main shafts 110 rotate synchronously in opposite directions, a roller 120 is used for clamping molten glass (not shown), and the roller 120 is continuously and quantitatively cooled through an air pipe 130 arranged in the main shafts 110, so that molten glass is cooled and shaped to form a determined glass plate width. In order to improve the above technical problem, in the present embodiment, during the manufacture of the edge-pulling shaft assembly 100, a supersonic flame spraying high-temperature wear-resistant coating treatment is performed on the outer circumferential side (a portion shown in fig. 4) of the roller 120, a composite material of a nickel-based alloy and a carbide is sprayed on the roller 120, and a wear-resistant coating (not shown in the figure) is formed on the outer circumferential side 121 of the roller 120. The wear-resistant coating at least comprises 15-25 wt% of nickel-based alloy (such as NiCr) and 70-80 wt% of carbide. In the embodiment, the content of the nickel-based alloy is about 20%, the carbide is chromium carbide wear-resistant particles, and the content of the chromium carbide wear-resistant particles is about 75%. The thickness of the wear resistant coating is about 50 μm. The coating can resist the high temperature of 1100-1400 ℃, the hardness of the coating is more than HV900, the bonding strength between the coating and the base material of the roller 120 is more than 70MPa, and the abrasion resistance of the roller 120 is enhanced. In addition, the wear resistant coating has a porosity < 1.0% and a coefficient of friction of 0.1.
In detail, referring to FIG. 4, the blank holder assembly 100 is a cooling source for the forming furnace, but actually, only the outer peripheral surface 121 of the roller 120 is required for the drawing process of the glass sheet. The forming process is negatively affected by the over-cooling of the front surface of the roller 120 and the portion of the spindle 110 entering the furnace. Because the working part of the edge-pulling shaft assembly 100 in the forming furnace is positioned below the platinum baffle (not shown), part of heat in the furnace can be taken away while cooling glass, so that the local temperature of the platinum baffle is reduced, the continuous reduction of the temperature can promote the crystallization of the platinum baffle, and the crystallization seriously affects the material liquid state of the formed high-temperature triangle after the crystallization occurs, so that the quality of the glass plate is difficult to control, and even the quality problems of warping and the like occur. In the present embodiment, in order to improve the above problem, supersonic speed or the like is applied to the surface of the main shaft 110 (portion B shown in fig. 4) and the end caps 122 of the rollers 120Ion spraying process of spraying ZrO2Or Al2O3The thermal barrier coating is formed by adopting a normal-temperature coating process of water-based ceramic paint. By utilizing the high temperature resistance, corrosion resistance and low heat conduction performance of the thermal barrier coating, the protection of the main shaft 110 and the end cover 122 of the roller 120 is realized, the outward conduction of heat in the furnace from the main shaft 110 and the end cover 122 is reduced, the occurrence of platinum baffle plate crystallization is delayed, and the impact of heat conduction on mechanical parts in the equipment main body 011 of the edge roller 010 is also relieved.
Optionally, the thickness of the thermal barrier coating formed by the supersonic plasma spraying process is 0.2-0.4 mm, and the bonding strength of the coating and the base material is 50-70 MPa. The thickness of the thermal barrier coating formed by the normal-temperature coating process of the water-based ceramic paint is 2-4 mm.
By applying the edge-drawing shaft assembly of the embodiment, the strength, the high-temperature creep resistance and the abrasion resistance of the main shaft and the roller are effectively enhanced, the deformation of the main shaft is reduced, the generation of molding crystallization is delayed, and the service life of the edge-drawing machine is synchronously prolonged, so that the important function of stabilizing the molding production of the substrate glass is played, and the edge-drawing shaft assembly is more suitable for the application of a G7.5/G8.5 advanced liquid crystal substrate glass molding production line.
In summary, the edge-pulling shaft assembly provided by the embodiment of the present invention includes a main shaft, a roller, and an air duct in the main shaft, wherein the main shaft has an inner cavity extending along the main shaft and penetrating through two ends of the main shaft, and the main shaft is provided with at least one exhaust hole communicated with the inner cavity; the roller is provided with an inner cavity and is communicated with the inner cavity of the main shaft, a flow channel is formed between the outer wall of the air pipe and the inner wall of the main shaft, the inner cavity of the air pipe is communicated with the inner cavity of the roller, a flow blocking part is arranged on the outer side of the air pipe, at least one exhaust hole is located between the flow blocking part and the roller, and the flow blocking part is used for forcing air in the flow channel to be exhausted out of the main shaft from the exhaust hole.
