Description

Technical Field

[0001] This application relates to the field of glass forming technology, and in particular to a glass forming apparatus. Background Technology

[0002] Glass, including but not limited to specialty glass and ordinary glass, is typically heat-bent in a single-chamber hot bending furnace. Heating and cooling occur within the furnace, and the glass is then bent into shape under its own weight. The single-chamber hot bending furnace includes a heating mechanism, specifically heating wires located at the top of the furnace body; no heating wires are present at the bottom. With the increasing prevalence of specialty glass, when specialty glass is formed using a single-chamber hot bending furnace, due to its relatively large thickness and complex shape, the resulting glass products are prone to bulging and cracking defects, resulting in poor surface quality. Therefore, this method cannot meet the forming requirements of many other types of glass. Summary of the Invention

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] It should be noted that the glass in this embodiment includes, but is not limited to, specialty glass or ordinary glass. Ordinary glass is two-layer laminated glass, that is, it includes two single panes of glass and adhesive connecting the two panes of glass. The thickness of ordinary glass is typically 4mm to 6mm. Specialty glass is at least three-layer laminated glass, and the thickness of specialty glass is greater than that of ordinary glass, generally greater than 10mm.

[0043] In one embodiment, this application primarily targets specialty glass products, including various models of specialty glass windshields and rear windows. Of course, this application is also applicable to all bus windshields and rear windows, all panoramic windows, and other products. This technical solution is also applicable to product combinations with different thicknesses and multi-layered glass combinations.

[0044] It should be noted that the terms "front," "rear," "up," "down," "left," and "right" in this embodiment refer to the actual state of the glass forming device during use. The side of the glass forming device facing the user is defined as "front," the side facing away from the user is defined as "rear," and the vertical direction is the up-down direction.

[0045] See Figures 1 to 3 An embodiment of this application provides a glass forming apparatus, comprising a furnace body 10 and a controller. The furnace body 10 forms a chamber and includes a first heating mechanism 11 and a second heating mechanism 12 disposed within the chamber. The first heating mechanism 11 is located above the second heating mechanism 12, and a space is provided between the first heating mechanism 11 and the second heating mechanism 12 for placing a glass 100 to be processed. The first heating mechanism 11 includes a plurality of first heating elements 111. The controller is electrically connected to the first heating mechanism 11 and is used to control the adjustment of the working power of each first heating element 111.

[0046] In the aforementioned glass forming apparatus, during the heating process of the glass to be processed 100 located between the first heating mechanism 11 and the second heating mechanism 12, the first heating mechanism 11 and the second heating mechanism 12 heat the glass to be processed 100 from the upper and lower sides respectively. This ensures that the upper, lower, and surrounding sides of the glass to be processed 100 are heated simultaneously, preventing uneven temperature distribution on the upper and lower surfaces or surrounding sides caused by heating only one side. This, in turn, avoids problems such as cracking, optical defects, and uneven transition of the formed surface during the forming process. Furthermore, since the first heating mechanism 11 includes multiple first heating elements 111, the controller can control and adjust the working power of each first heating element 111 according to the shape requirements of the glass to be processed 100, thereby further improving the temperature uniformity of the glass to be processed 100 and meeting the forming requirements of more types of glass.

[0047] For example, the first heating element 111 may include, but is not limited to, a heating wire, a heating plate, or a heating tube. In this embodiment, the first heating element 111 is specifically described as a heating wire, but it is not limited thereto.

[0048] For example, the longitudinal direction of the first heating element 111 is parallel to the side surface of the glass 100 to be processed. Optionally, the first heating element 111 can be arranged along the transverse direction of the chamber, along the longitudinal direction of the chamber, or in other ways. The transverse direction of the chamber is also the left-right direction, such as... Figure 1 or Figure 3 The direction indicated by the Y-axis; the longitudinal direction of the chamber, that is, the front-to-back direction, such as... Figure 1 or Figure 3 The direction indicated by the X-axis in the diagram.

[0049] Multiple first heating elements 111 are located above the glass 100 to be processed and are respectively opposite to multiple different positions of the glass 100 to be processed. In this way, when each first heating element 111 is working, it can heat different positions of the glass 100 to be processed, thereby improving the uniformity of heating.

[0050] For example, the heating area of ​​the first heating mechanism 11 completely covers the glass 100 to be processed by its orthographic projection along the vertical direction. This facilitates uniform heating of different locations on the glass 100 to be processed.

[0051] Optionally, the ratio of the area of ​​the glass to be processed 100 to the heating area of ​​the first heating mechanism 11 is K, where 0.1 ≤ K ≤ 0.9. Specifically, the area of ​​the glass to be processed 100 refers to the surface area of ​​the glass plane in a flat state, or the projected area of ​​the glass on a horizontal plane in a curved state, where K = 0.1, 0.3, 0.5, 0.7, or 0.9, etc. In this way, the heating area of ​​the first heating mechanism 11 is larger than the area of ​​the glass to be processed 100, resulting in a larger heating area and a correspondingly larger internal space of the chamber, which can accommodate special glass with a larger area and be used to uniformly heat and process the special glass.

[0052] For example, the plurality of first heating elements 111 include a plurality of movable elements whose positions can be adjusted vertically. The movable elements refer to the first heating elements 111 whose positions can be adjusted vertically relative to the glass to be processed 100. The glass forming apparatus also includes a plurality of first lifting mechanisms 14, each first lifting mechanism 14 being connected to a corresponding movable element. The first lifting mechanism 14 is used to adjust the height position of the movable element, and is electrically connected to a controller, which also controls the lifting action of the first lifting mechanism 14. Thus, the controller can not only adjust the working power of each first heating element 111, but also control the operation of each first lifting mechanism 14 to adjust the height position of the corresponding movable element according to the surface requirements of the glass product, ensuring that the distance between the movable element and the glass to be processed 100 meets the requirements, thereby improving the temperature uniformity of the glass to be processed 100, improving the surface quality of the glass product, and meeting the forming needs of more types of glass.

[0053] Optionally, the first lifting mechanism 14 may include, but is not limited to, a motor screw, a pneumatic cylinder, or a hydraulic cylinder.

[0054] For example, the plurality of first heating elements 111 also include a plurality of fixed members 1113 whose positions cannot be adjusted. The fixed members 1113 refer to the first heating elements 111 whose positions cannot be adjusted, and are fixed relative to the chamber and the glass 100 to be processed. Specifically, the plurality of fixed members 1113 are fixedly disposed in the middle portion of the chamber. Thus, during the heating process of the glass 100 to be processed, the plurality of fixed members 1113 are disposed opposite to the middle portion of the glass 100 to be processed, for heating the middle portion of the glass 100 to be processed. And because the middle portion of the glass 100 to be processed is relatively flat, the plurality of fixed members 1113 typically do not need to be adjusted in height to ensure the uniformity of heating of the glass 100 to be processed.

[0055] Since the opposite sides of the glass to be processed 100 are curved, the height of the first heating element 111, which is opposite to the opposite sides of the glass to be processed 100, can be adaptively adjusted according to the surface requirements, thereby improving the uniformity of heating of the surface of the glass to be processed 100.

[0056] Specifically, when the temperature at a certain location of the glass 100 to be processed is low, the controller can adjust the height of the first heating element 111, which is set at a height-adjustable position relative to that location, for example, by lowering the height, thereby reducing the distance between the first heating element 111 and the glass 100 to be processed, so that the temperature of a local part of the glass 100 to be processed increases.

[0057] Based on the foregoing embodiments, the glass forming apparatus further includes a temperature sensor. The temperature sensor is, for example, an infrared imager. The temperature sensor can sense the temperature distribution on the surface of the glass 100 to be processed. The controller controls the first lifting mechanism 14 to operate based on the temperature distribution of the surface sensed by the temperature sensor, and / or controls the first heating element 111 to adjust its operating power, so that the temperature distribution at different locations on the surface is uniform.

[0058] During the heating process of the glass 100 to be processed, since the temperature change range of the parts with larger surface curvature is greater than that of the parts with smaller surface curvature, in this embodiment, in some optional schemes, the operation of the first lifting mechanism 14 and / or the working power of the first heating element 111 can be adjusted according to the curvature of the surface. Specifically, when the curvature of the surface is large, the height position of the first heating element 111 is lowered by the first lifting mechanism 14, and / or the working power of the first heating element 111 is increased; conversely, when the curvature of the surface is small, the height position of the first heating element 111 is raised by the first lifting mechanism 14, and / or the working power of the first heating element 111 is decreased.

[0059] For example, the plurality of movable parts includes a plurality of first movable parts 1111 and a plurality of second movable parts 1112. The plurality of first movable parts 1111 are located on one side of the plurality of fixed parts 1113 and are used to heat one side of the glass 100 to be processed; the plurality of second movable parts 1112 are located on the other side of the plurality of fixed parts 1113 and are used to heat the other side of the glass 100 to be processed. Optionally, in this embodiment, the plurality of first movable parts 1111 are distributed, for example, on the left side of the chamber, and the plurality of second movable parts 1112 are distributed, for example, on the right side of the chamber.

[0060] Optionally, the number of the first movable component 1111 and the number of the second movable component 1112 can be the same or different. The specific number can be flexibly adjusted and set according to actual needs, and no limitation is made here.

[0061] In actual operation, the furnace body 10 can be adjusted in position as a whole or independently; the multiple second movable parts 1112 can be adjusted in position as a whole or independently. No specific limitation is made here, and they can be adjusted and set according to actual needs.

[0062] For example, the number of the first heating element 111 may be, but is not limited to, 300 to 1200, specifically 300, 500, 700, 900 or 1200, etc., which can be flexibly adjusted and set according to actual needs.

[0063] Optionally, the number of movable parts is not limited to 200 to 700, specifically, for example, 200, 300, 350, 400, 450, 500, 550, 600, or 700. With a larger number of movable parts, i.e., a larger number of first heating elements 111 that can be raised and lowered for adjustment, the length of each movable part can be designed to be shorter, reducing the heat radiation area. This allows for targeted and precise temperature adjustment of many different areas according to the surface requirements of the glass 100 to be processed, improving the heating uniformity of the glass 100 and resulting in higher glass product quality.

[0064] Optionally, the number of fasteners 1113 may include, but is not limited to, 100 to 600, specifically, 100, 300, 400, 500 or 600.

[0065] For example, multiple first heating elements 111 are arranged in multiple rows. The number of rows of the first heating elements 111 is 5 to 9, specifically, for example, 5, 6, 7, 8 or 9. Optionally, the number of first heating elements 111 in each row is 50 to 80, specifically, for example, 50, 60, 70, 80 or 90.

[0066] Based on the aforementioned embodiment, multiple movable members are arranged in multiple rows. The number of rows of movable members is 5 to 9, and the number of movable members in each row is 40 to 60. Specifically, the movable members extend along the transverse direction Y of the chamber. Similarly, multiple fixing members 1113 are arranged in multiple rows; the number of rows of fixing members 1113 is 5 to 9, and the number of fixing members 1113 in each row is 10 to 20.

[0067] Please see Figure 1 and Figure 3 For example, the first heating mechanism 11 further includes a plurality of second heating elements 112. The controller is also used to control the adjustment of the operating power of each second heating element 112; the extension direction of the first heating element 111 is set at an angle to the extension direction of the second heating element 112. Thus, not only can the glass 100 to be processed be heated by the first heating element 111, but the glass 100 to be processed can also be heated by the second heating elements 112, and the operating power of both the first heating element 111 and the second heating element 112 can be adjusted under the control of the controller, and the extension direction of the first heating element 111 is set at an angle to the extension direction of the second heating element 112, thereby improving the heating uniformity of the glass 100 to be processed.

[0068] Similarly, the second heating element 112 may include, but is not limited to, a heating wire, a heating plate, or a heating tube. In this embodiment, the second heating element 112 is specifically described as a heating wire, but it is not limited thereto.

[0069] For example, the first heating element 111 extends along the longitudinal direction X of the chamber, and the second heating element 112 extends along the transverse direction Y of the chamber.

[0070] For example, the second heating element 112 is fixedly disposed in the middle of the chamber, and multiple second heating elements 112 are arranged vertically spaced from multiple first heating elements 111. Specifically, the multiple second heating elements 112 are located below the multiple first heating elements 111. In this way, on the one hand, the second heating elements 112 have a non-adjustable height position, and the distance between them and the glass to be processed 100 remains unchanged. Furthermore, the second heating elements 112 are aligned with the middle part of the glass to be processed 100, eliminating the need to adjust their height position vertically and preventing interference with the first movable member 1111 and the second movable member 1112, which have adjustable height positions. On the other hand, the second heating elements 112 and the fixing member 1113 are both located in the middle of the chamber and their extension directions are arranged at an angle, which helps to improve the heating uniformity of the glass to be processed 100. In addition, the second heating elements 112 and the first heating elements 111 are spaced apart vertically, thereby avoiding contact between them and short-circuit defects.

[0071] Optionally, the vertical distance between the second heating element 112 and the first heating element 111 is, but is not limited to, 30mm to 50mm, specifically, 30mm, 40mm or 50mm.

[0072] Optionally, the number of second heating elements 112 may include, but is not limited to, 16 to 30. Furthermore, a plurality of second heating elements 112 may be arranged sequentially along the longitudinal direction of the chamber.

[0073] For example, the distribution of each first heating element 111 and each second heating element 112 can be either symmetrical or asymmetrical, without limitation. The operating power of each first heating element 111 and each second heating element 112 can be controlled symmetrically or asymmetrically, and the maximum temperature can reach about 850°C.

[0074] For example, since the first heating element 111 is located above the second heating element 112, the first heating element 111 is closer to the top wall of the chamber, and the distance between the first heating element 111 and the top wall of the chamber is, for example, 40 mm to 60 mm.

[0075] The first heating element 111 and the second heating element 112 in this application are more numerous, more finely distributed, and have more targeted parameter settings, which makes the surface transition of the glass forming process smoother.

[0076] Please see Figures 4 to 6 For example, the second heating mechanism 12 includes a plurality of third heating elements 121. A controller is electrically connected to the second heating mechanism 12 and is used to control the adjustment of the operating power of each third heating element 121.

[0077] For example, the third heating element 121 may include, but is not limited to, a heating wire, a heating plate, or a heating tube. In this embodiment, the third heating element 121 is specifically described as a heating wire, but it is not limited thereto.

[0078] For example, the longitudinal direction of the third heating element 121 is parallel to the side of the glass 100 to be processed. Optionally, the third heating element 121 may be arranged along the transverse direction of the chamber, along the longitudinal direction of the chamber, or extending in other directions.

[0079] Multiple third heating elements 121 are located below the glass to be processed 100 and are respectively opposite to multiple different positions of the glass to be processed 100. In this way, when each third heating element 121 is working, it can heat different positions on the lower side of the glass to be processed 100, thereby improving the uniformity of heating.

[0080] For example, the heating area of ​​the third heating mechanism completely covers the glass 100 to be processed by its orthographic projection along the vertical direction. This facilitates uniform heating of different locations on the glass 100 to be processed.

[0081] For example, multiple third heating elements 121 are arranged in multiple rows. Specifically, the number of rows of the third heating elements 121 is 3 to 7, for example, 3, 4, 5, 6, 7 or other numbers. The number of third heating elements 121 in each row is 50 to 80, for example, 50, 60, 70, 80 or other numbers, which are not limited here.

[0082] In this application, both the first heating mechanism 11 and the second heating mechanism 12 are electrically connected to the controller. The first heating element 111, the second heating element 112, and the third heating element 121 independently adjust their working power under the control of the controller, and there are a large number of these elements. This allows for intelligent temperature control, with the heating process set to 10-30 stages of heat preservation, improving the heating uniformity of the glass and solving problems such as cracking, optical defects, and uneven transition of the formed surface caused by large temperature differences between the upper and lower layers during glass heating.

[0083] Please see Figure 4 For example, the glass forming apparatus also includes a blower 20. The blower 20 is mounted on the furnace body 10 and is used to blow cold air from outside the furnace body 10 into the furnace body 10. Thus, after the hot bending process of the glass to be processed 100 is completed, the furnace body 10 is opened, the first heating mechanism 11 and the second heating mechanism 12 stop heating, and cold air is blown into the furnace body 10 by the blower 20. The cold air can lower the temperature of the glass to be processed 100, thereby achieving cooling and solidification of the glass to be processed 100.

[0084] Optionally, the fan 20 may be, but is not limited to, a centrifugal fan. Furthermore, the fan 20 may also be, for example, a variable frequency fan.

[0085] Please see Figure 4 For example, the furnace body 10 has four sides, and each side is equipped with a fan 20. In this way, when the fans 20 on each side work synchronously, each fan 20 can blow cold air from outside the furnace body 10 into the furnace body 10, so that cold air is available in all positions inside the furnace body 10, thereby cooling all positions of the glass 100 to be processed, thus improving the cooling and curing effect of the glass 100 to be processed.

[0086] Optionally, the number of fans 20 may include, but is not limited to, one, two, three, or any other arbitrary number, which can be flexibly adjusted and set according to actual needs. The operating power of the fans 20 is adjustable from 0% to 100%.

[0087] In this application, the total number of fans 20 is, for example, 8 to 12. Thus, the large number of fans 20 enables rapid annealing and forming of the glass 100 to be processed.

[0088] In one specific embodiment, the blower 20 is a centrifugal variable frequency blower. At least two blowers 20 are provided on each side of the furnace body 10, and each side is equipped with a regulating valve for manually controlling and adjusting the blowing direction of the blowers 20. The regulating valve is specifically located on the air inlet pipe of the blower 20. The regulating valve includes, but is not limited to, a manual regulating valve or an electric regulating valve. Thus, by adjusting the valve, the blowing direction of the blower 20 can be adjusted accordingly, ensuring that the blowing direction of the blower 20 meets the requirements, thereby controlling the temperature inside the furnace body 10 to meet the cooling and annealing requirements of the glass 100 to be processed.

[0089] Of course, as some optional solutions, the centrifugal fans are not limited to being arranged on each side of the furnace body 10 as in the above embodiments. They can also be arranged on two opposite sides of the furnace body 10, while the other two sides of the furnace body 10 do not need to be equipped with fans 20. The specific number and arrangement of the fans 20 can be flexibly adjusted and set according to actual needs, and are not limited here.

[0090] For example, there are at least two side fans 20, arranged sequentially along the outer periphery of the furnace body 10, with the outlet sides of two adjacent fans 20 facing away from each other. In this way, the outlet directions of two adjacent fans 20 are opposite to each other, resulting in a wider purging area. This effectively reduces the temperature of various parts of the glass 100 to be treated, allowing for simultaneous cooling of all parts of the glass and thus improving the surface quality of the glass product.

[0091] For example, the blower 20 may be selected as a blower with a swivel function, which can further increase the range of the blowing area, so that more parts of the glass 100 to be treated are cooled sufficiently and evenly.

[0092] Please see Figure 4 For example, the furnace body 10 is provided with an observation window 13, through which the forming status of the glass 100 to be processed inside the chamber can be observed. Each side of the furnace body 10 can be provided with an observation window 13 according to actual needs. For example, the observation window 13 can be funnel-shaped, with the outer opening diameter larger than the inner opening diameter. The number of observation windows 13 is not limited; it can be one, three, five, or other numbers.

[0093] For example, the glass forming apparatus also includes an illumination mechanism 30 disposed outside the furnace body 10, which includes, but is not limited to, a lamp. The illumination mechanism 30 is located beside the observation window 13. The light from the illumination mechanism 30 can enter the furnace body 10 through the observation window 13, thereby facilitating observation of the forming process of the glass 100 to be processed inside the furnace body 10.

[0094] To prevent the light from being too bright, for example, baffles are provided on both the left and right sides of the observation window 13, which are movable outside the furnace body 10 and are used to block the light.

[0095] Please see Figure 4 For example, the furnace body 10 includes a main body 101 and a cover 102. The cover 102 is located below the main body 101 and can be opened. A chamber is formed in the main body 101, and an observation window 13 is specifically provided on the main body 101 and communicates with the chamber. The lighting mechanism 30 is specifically connected and fixed to the main body 101.

[0096] Based on the aforementioned embodiment, the first heating mechanism 11 is disposed within the main body 101, and the second heating mechanism 12 is connected to the cover 102. Thus, when the cover 102 is opened, the glass to be processed 100 can be placed into the furnace body 10; when the cover 102 and the main body 101 are closed, the glass to be processed 100 inside the furnace body 10 is heated by the first heating mechanism 11 and the second heating mechanism 12. Because the cover 102 and the main body 101 are closed, heat leakage is prevented, thereby improving the forming quality of the glass to be processed 100.

[0097] The controller is equipped with an annealing start time point. When the annealing start time point is reached, the controller accordingly controls the cover 102 to open and performs the annealing cooling operation. This allows for precise control of the annealing timing, preventing the cover 102 from opening prematurely, and thus better controlling the edge stress of the glass product.

[0098] Please see Figure 8 and Figure 9 For example, the glass forming apparatus also includes a first support frame 41 and a second lifting mechanism 50. The main body 101 is connected to the first support frame 41. The second lifting mechanism 50 is connected to the cover 102 and is used to lift the cover 102. Thus, the first support frame 41 is placed on the ground or a workbench, and the main body 101, being mounted on the first support frame 41, remains stationary and is stably supported by the first support frame 41. When it is necessary to open the cover 102, the second lifting mechanism 50 causes the cover 102 to descend, separating the cover 102 from the main body 101; when it is necessary to close the cover 102, the second lifting mechanism 50 causes the cover 102 to rise, closing the cover 102 from the main body 101.

[0099] For example, the glass forming apparatus also includes a second support frame 42 and a third support frame 43. The third support frame 43 is slidably engaged with the second support frame 42 in the vertical direction. A second lifting mechanism 50 is mounted on the second support frame 42, and the cover 102 is mounted on the third support frame 43. The second lifting mechanism 50 is connected to the third support frame 43. Thus, when the second lifting mechanism 50 drives the third support frame 43 to move up and down, the third support frame 43 slides along the second support frame 42, thereby driving the furnace cover to move up and down. The lifting movement of the cover 102 has high stability.

[0100] For example, the second support frame 42 is provided with a slide rail 421, and the third support frame 43 is provided with a slider that slides in cooperation with the slide rail 421. The slider slides along the slide rail 421, which guides the third support frame 43, thereby improving the lifting stability of the third support frame 43.

[0101] For example, the first support frame 41 is installed on the ground. A first pit is provided on the ground, and the second support frame 42 and the second lifting mechanism 50 are disposed in the first pit. Optionally, the distance between the inner wall of the first pit and the outer wall of the cover 102 is less than 50mm, and they should not interfere with the lifting action of the cover 102.

[0102] Based on the aforementioned embodiments, entrances and exits are provided on the left and right opposite sides of the first pit, allowing maintenance personnel to enter the first pit through the entrances and exits, facilitating maintenance operations of the second lifting mechanism 50, the cover 102, and the second heating mechanism 12.

[0103] Please see Figure 8 and Figure 9 To improve the safety of the first pit, the third support frame 43 is equipped with pedals 431 on both the front and rear opposite sides. When the third support frame 43 drives the cover 102 to close with the main body 101, the pedals 431 rise with the third support frame 43 and, for example, become flush with the ground; when the third support frame 43 drives the cover 102 to descend into the first pit, the pedals 431 descend into the first pit according to the third support frame 43.

[0104] Please see Figure 5 and Figure 6 For example, the cover 102 has a recessed mounting groove 1021 on the side facing the main body 101, which is recessed away from the main body 101, and the second heating mechanism 12 is disposed in the mounting groove 1021. The furnace body 10 also includes a protective net 60, which is connected to the cover 102 and disposed at the opening of the mounting groove 1021. The protective net 60 is located on the side of the second heating mechanism 12 facing the main body 101.

[0105] Optionally, the protective net 60 may be, but is not limited to, a metal wire mesh, such as iron wire mesh or copper wire mesh. The mesh of the metal wire mesh may be, but is not limited to, polygonal or circular.

[0106] For example, the protective net 60 is flush with the edge of the groove of the mounting groove 1021.

[0107] For example, the vertical distance between the protective net 60 and the second heating mechanism 12 is, for example, 40mm to 60mm. This prevents the protective net 60 from contacting the second heating mechanism 12 and causing a short circuit.

[0108] For example, the cover 102 may be made of insulating material, such as cotton blocks, to provide good insulation. The thickness of the bottom wall of the cover 102 may be, but is not limited to, 200mm to 400mm.

[0109] For example, the main body 101 may be made of insulating materials, such as insulating cotton blocks. Optionally, the insulation thickness of the side walls of the main body 101 is 200mm to 400mm, and the insulation thickness of the top wall of the main body 101 is 200mm to 450mm. This improves the insulation effect of the furnace body 10, ensuring that the measurable temperature of the outer furnace wall does not exceed 50°C in summer and 35°C in winter.

[0110] For example, a first sealing ring 1022 is provided on the outer peripheral edge of the side of the cover 102 facing the main body 101. The first sealing ring 1022 abuts against the main body 101 in a sealing manner. Thus, when the cover 102 and the main body 101 abut against each other, the first sealing ring 1022 plays a sealing role, improving the airtightness of the chamber.

[0111] Optionally, the first sealing ring 1022 may include, but is not limited to, a sealing element made of insulating cotton rope or other materials, with the insulating cotton rope wrapping around the outer periphery of the cover 102 one, two, or three times. The diameter of the insulating cotton rope is, for example, 30mm to 60mm.

[0112] For example, the glass forming apparatus also includes a forming mold 70. The forming mold 70 is used to place the glass to be processed 100, and the forming mold 70 is placed on the cover 102. The forming mold 70 serves to support the outer peripheral edge of the glass to be processed 100, which is gradually heat-bent and formed after being heated.

[0113] It should be noted that the placement in this embodiment can be either direct or indirect, and can be set according to actual needs, without limitation here.

[0114] During the heating process, the outer periphery of the glass 100 to be processed is supported by the forming mold 70. If the middle part is not supported, it will easily sink due to excessive gravity, resulting in cracking defects.

[0115] Please see Figure 1 , Figures 5 to 7For example, the cover 102 is provided with a support rod 1023 and an adjustment mechanism (not shown in the figure). The support rod 1023 is used to support the middle part of the glass 100 to be processed. The adjustment mechanism is connected to the support rod 1023 and can raise and lower the support rod 1023 to adjust its height. The adjustment mechanism is electrically connected to the controller. In this way, the adjustment mechanism can adaptively raise and lower the support rod 1023 according to different heating stages of the glass 100 to be processed. By supporting the middle part of the glass 100 to be processed with the top of the support rod 1023, the stability of the glass 100 to be processed during the heating process is ensured, and excessive sagging of the middle of the glass 100 to be processed is prevented, thereby avoiding cracking defects during the heating process.

[0116] The number of support rods 1023 includes, but is not limited to, one or more. Multiple rods may be two, three, or more, depending on actual needs. In this embodiment, for example, there are two support rods 1023, and correspondingly two adjustment mechanisms are set, with each adjustment mechanism corresponding to each support rod 1023.

[0117] For example, the height of the support rod 1023 can be automatically controlled by the molding process based on the temperature setting and lifting distance, or it can be manually adjusted according to actual needs.

[0118] For example, there are multiple support rods 1023 and multiple adjustment mechanisms, with each adjustment mechanism corresponding to each support rod 1023.

[0119] For example, the adjustment mechanism can also adjust the position of the support rod 1023 along the front-back direction of the chamber. By adjusting the position of the support rod 1023 along the front-back direction of the chamber, the support position of the support rod 1023 on the glass 100 to be processed in the front-back direction can be adjusted.

[0120] For example, the adjustment mechanism includes a servo motor. The servo motor controls the lifting and lowering of the support rod 1023, and the automatic lifting and lowering of the support rod 1023 can be set to 5 to 20 stages. The front and rear support rods 1023 can be controlled separately. The support position can be automatically controlled and adjusted according to the product structure, realizing intelligent control of the product bending and forming process and improving product quality.

[0121] To avoid the support rod 1023, two protective nets 60 are provided, for example, forming a clearance portion 61 between the two protective nets 60. The support rod 1023 is located at the clearance portion 61 and can move along the clearance portion 61 under the drive of the adjustment mechanism. Similarly, the third heating elements 121 of the second heating mechanism 12 are distributed on opposite sides of the support rod 1023. Specifically, the two protective nets 60 are arranged symmetrically about the clearance portion 61. The third heating elements 121 of the second heating mechanism 12 are also arranged symmetrically about the clearance portion 61.

[0122] Please see Figure 1 , Figure 2 , Figure 10 and Figure 11 For example, the glass forming apparatus also includes a moving carrier 80. The moving carrier 80 is used to load the forming mold 70, move the forming mold 70 into the chamber and place it on the cover 102, and move the forming mold 70 out of the chamber. In this way, the forming mold 70 and the cover 102 are separable, and the moving carrier 80 enables the forming mold 70 and the glass 100 to be processed to be moved into or out of the chamber without manual handling of the forming mold 70, thus increasing automation, improving the working environment, and enhancing safety. Furthermore, since personnel do not need to enter the chamber, damage to the first sealing ring 1022 due to personnel stepping on it is prevented.

[0123] For example, a second sealing ring 81 is provided on the outer peripheral edge of the top of the mobile carrier 80. The second sealing ring 81 is in sealing contact with the main body 101. Thus, when the cover 102 lifts the mobile carrier 80 to contact the main body 101, the second sealing ring 81 on the mobile carrier 80 simultaneously contacts the main body 101, and the second sealing ring 81 plays a sealing role, improving the airtightness of the chamber.

[0124] Optionally, the second sealing ring 81 may include, but is not limited to, a seal made of insulating cotton rope or other materials, with the insulating cotton rope wrapping around the outer periphery of the mobile carrier 80 one, two, or three times. The diameter of the insulating cotton rope is, for example, 30mm to 60mm.

[0125] Optionally, the mobile vehicle 80 may include, but is not limited to, a mobile trolley, a robotic arm, a conveyor chain, etc., as long as it meets the requirements of a mobile forming vehicle.

[0126] For example, the glass forming apparatus also includes a guide rail 91 extending from outside the chamber into the chamber, and a moving carrier 80 is slidably disposed on the guide rail 91. Thus, guided by the guide rail 91, the moving carrier 80 stably enters the chamber.

[0127] For example, there are two guide rails 91. The two guide rails 91 are arranged side by side with a gap between them, and the two guide rails 91 extend into the cavity. The guide rails 91 are mounted on the ground or on the workbench surface. In this embodiment, the guide rails 91 are specifically mounted on the ground, and the upper surface of the guide rails 91 is flush with the ground.

[0128] For example, the glass forming apparatus also includes a pushing mechanism. The pushing mechanism provides power to slide the moving carrier 80 along the guide rail 91, thereby moving it into or out of the chamber. The pushing mechanism is, for example, a servo motor, electrically connected to a controller. The travel distance of the moving carrier 80 on the guide rail 91 can be flexibly adjusted and set according to actual needs. The servo motor can accurately control the upper and lower positions of the moving carrier 80 and its waiting-to-lift position, ensuring that the position of the moving carrier 80 remains consistent after each movement.

[0129] To ensure that the position of the mobile carrier 80 remains consistent after each movement, the furnace body 10 is equipped with a reset sensor. The reset sensor is electrically connected to the controller. The reset sensor is used to sense the position of the mobile carrier 80 and send the position signal of the mobile carrier 80 to the controller. The controller calibrates the push mechanism according to the position signal, thereby achieving precise control of the position of the mobile carrier 80.

[0130] For example, the mobile vehicle 80 adopts an open frame structure 82, which specifically includes multiple square tube splicing combinations. Three to four moving wheels 86 are fixed on each of the opposite sides of the mobile vehicle 80, and the moving wheels 86 move along the guide rail 91.

[0131] For example, the mobile carrier 80 also includes a first connecting rod 83 and a second connecting rod 84 connected within the frame structure 82. Multiple first connecting rods 83 and second connecting rods 84 are provided, with the multiple first connecting rods 83 arranged at intervals and the multiple second connecting rods 84 arranged at intervals. The first connecting rods 83 and second connecting rods 84 are staggered. Thus, the first connecting rods 83 and second connecting rods 84 form openings, which, while providing stable support for the molding die 70, allow heat to be transferred upwards through the openings to the lower side of the glass 100 to be processed.

[0132] For example, the mobile carrier 80 is provided with a first auxiliary heat joint 85, and the main body 101 is provided with a second auxiliary heat joint corresponding to the position of the first auxiliary heat joint 85. When the cover 102 drives the mobile carrier 80 to move upward and close the main body 101, the first auxiliary heat joint 85 and the second auxiliary heat joint are connected to complete the power supply, and the auxiliary heating device on the forming body starts heating, so as to better realize the forming of a local small curvature spherical surface, and the surface forming quality of the glass product meets the requirements.

[0133] Please see Figures 11 to 15 For example, the glass forming apparatus also includes a third lifting mechanism 92. The third lifting mechanism 92 is detachably connected to a first lifting member 93 for lifting the glass 100 to be processed or a second lifting member 94 for lifting the forming mold 70, and the third lifting mechanism 92 can drive the first lifting member 93 or the second lifting member 94 to move up and down.

[0134] The first lifting component 93 includes, but is not limited to, a tray, which can stably support the glass to be processed 100 and drive the glass to be processed 100 to rise and fall with the lifting action of the third lifting mechanism 92.

[0135] For example, there are two first lifting components 93, which are arranged side by side with a gap between them. When the third lifting mechanism 92 is activated, it can synchronously drive the two first lifting components 93 to lift and lower, thereby realizing the lifting and lowering of the glass 100 to be processed.

[0136] To prevent damage to the glass, for example, the top surface of the tray is fixed with fiberglass cloth or PBO material.

[0137] The third lifting mechanism 92 is electrically connected to the controller. Under the control of the controller, the lifting stroke of the third lifting mechanism 92 can be flexibly adjusted according to actual needs.

[0138] The second lifting component 94 includes, but is not limited to, a pipe, which can stably support the glass 100 to be processed, and drive the molding die 70 to rise and fall with the rising and falling action of the third lifting mechanism 92.

[0139] For example, there are two second lifting components 94, which are arranged side by side with intervals. When the third lifting mechanism 92 is activated, it can synchronously drive the two second lifting components 94 to lift and lower, thereby realizing the lifting and lowering of the glass 100 to be processed.

[0140] When the glass to be processed 100 needs to be replaced, the third lifting mechanism 92 is connected to the first lifting member 93; when the forming mold 70 needs to be replaced, the third lifting mechanism 92 is connected to the second lifting member 94. Thus, after the glass to be processed 100 is lifted upwards by the first lifting member 93, there is a space between the glass to be processed 100 and the forming mold 70 below it. This space facilitates the transfer of the lifted glass to be processed 100 by the loading and unloading device, thereby facilitating operations such as loading, unloading, and changing materials, and reducing labor intensity. Similarly, the forming mold 70 is lifted upwards by the second lifting member 94, and there is a space between the forming mold 70 and the moving carrier 80 below it, thereby facilitating operations such as loading, unloading, and changing the forming mold 70, reducing labor intensity, and eliminating the need for manual handling.

[0141] For example, a second pit is provided in the ground, and a third lifting mechanism 92 is disposed in the second pit. The glass forming apparatus also includes a protective plate 95, which seals the opening of the second pit. The third lifting mechanism 92 includes a lifting rod 921 that passes through the protective plate 95, and a mounting member 96 is connected to the top end of the lifting rod 921. The mounting member 96 can be used to install a first lifting member 93 or a second lifting member 94. Optionally, the mounting member 96 may be, for example, a mounting box or a mounting plate.

[0142] The second lifting mechanism 50 and the third lifting mechanism 92 can be flexibly adjusted and set according to actual needs, including but not limited to motor screws, cylinders or hydraulic cylinders.

[0143] To make the working principle of the glass forming apparatus in this application clearer, one embodiment of the glass forming apparatus includes the following steps:

[0144] Step S110: The mobile carrier 80 moves along the guide rail 91 to the upper and lower piece positions. The replacement of the glass to be processed 100 or the forming mold 70 can be achieved by the third lifting mechanism 92 and the first lifting component 93 or the second lifting component 94.

[0145] Specifically, when the glass to be processed 100 is replaced, the third lifting mechanism 92 is connected to the first supporting component 93; when the molding mold 70 is replaced, the third lifting mechanism 92 is connected to the second supporting component 94.

[0146] In step S120, the moving carrier 80 drives the molding mold 70 and the glass to be processed 100 placed on it into the cavity and moves to the waiting position for lifting.

[0147] In step S130, the second lifting mechanism 50 drives the cover 102 to rise. As the cover 102 rises, the moving carrier 80, the forming mold 70, and the glass to be processed 100 are also lifted to achieve the closure of the cover 102 and the main body 101.

[0148] Both the first sealing ring 1022 and the second sealing ring 81 abut against the main body 101, thereby improving the sealing between the cover 102 and the main body 101.

[0149] The first auxiliary heat connector 85 and the second auxiliary heat connector are connected to complete the power supply. The auxiliary heating device on the forming body then starts heating, which better achieves the forming of a spherical surface with a small curvature in a localized area. The surface forming quality of the glass product meets the requirements.

[0150] In step S140, the first heating mechanism 11 and the second heating mechanism 12 perform heating operations simultaneously, and the glass to be processed 100 softens under heat and obtains the desired surface.

[0151] Step S150: When the glass to be processed 100 has the required surface shape, both the first heating mechanism 11 and the second heating mechanism 12 stop working.

[0152] In step S160, the second lifting mechanism 50 drives the glass with the required shape and the mobile carrier 80 to descend.

[0153] In step S170, the fan 20 operates, blowing cold air to the glass 100 to be treated, thereby cooling the glass 100.

[0154] Step S180: After the glass to be processed 100 cools and solidifies, the moving carrier 80 drives the forming mold 70 and the glass to move out of the chamber.
