Description

Technical Field

[0001] This disclosure relates to the technical field of curved glass, and more particularly to a curved glass processing device. Background Technology

[0002] Hot-bent glass is a building and decorative material made by heating flat glass to its softening temperature, shaping it into a curved surface in a mold using gravity or external force, and then annealing and cooling it. It is widely used in building curtain walls, skylights, curved staircases, and electronic equipment, combining functionality and aesthetic value.

[0003] In some cases, flat glass needs to be partially bent by hot bending, meaning there are sections that need to maintain their flat shape. However, during the process, because the glass is at its softening temperature, the entire glass is subjected to thermal bending forces, and the flat areas may develop defects such as indentations and pitting under the influence of external forces. Utility Model Content

[0004] One of the technical problems that this disclosure aims to solve is the issue that surface defects are prone to occur in the unformed parts of hot-bent glass.

[0005] To solve the above-mentioned technical problems, this disclosure provides a curved glass processing device, which includes a forming module and a non-forming module arranged along a first horizontal direction. The forming module is configured to heat the part of the flat glass to be formed to a softening temperature and realize the hot bending forming of the part to be formed. The non-forming module is configured to clamp and support the non-forming part of the flat glass and heat the non-forming part to a buffer temperature below the softening temperature.

[0006] In some embodiments, the softening temperature is 580–680°C, and the buffer temperature is 400–520°C.

[0007] In some embodiments, the non-formed module includes a lower support plate, an upper support plate located above the lower support plate, and a first telescopic cylinder. The lower support plate has a flat support surface at the top, the upper support plate has a flat support surface at the bottom, and the first telescopic cylinder is capable of driving the upper support plate to move vertically relative to the lower support plate.

[0008] In some embodiments, a heating element is provided in the upper support plate and / or the lower support plate.

[0009] In some embodiments, a positioning insert is further included, which can be driven to move to and away from the lower support plate, and the positioning insert can be driven to move toward the molding module along the first horizontal direction to adjust the position of the flat glass on the lower support plate.

[0010] In some embodiments, the forming module includes a hot bending template, a pressure plate located on the upper side of the hot bending template, and a second telescopic cylinder. The hot bending template has a curved surface located at the top, and the second telescopic cylinder is capable of driving the pressure plate to move vertically toward the hot bending template.

[0011] In some embodiments, the curved surface extends about an axis in a second horizontal direction and convexes upward, the second horizontal direction being perpendicular to the first horizontal direction, the pressure plate having a flat lower surface, the pressure plate being connected to the second telescopic cylinder via a rotating mechanism capable of driving the pressure plate to rotate about an axis along the second horizontal direction.

[0012] In some embodiments, the second telescopic cylinder can be driven to move along the first horizontal direction to move the pressure plate along the first horizontal direction.

[0013] In some embodiments, the pressure plate and / or the hot bending template are provided with heating elements.

[0014] In some embodiments, in the first horizontal direction, the height of the curved surface gradually decreases along the direction from the non-forming module toward the forming module.

[0015] Through the above technical solution, the non-formed module can support and heat the non-formed part, so that the non-formed part can remain in a flat state, with virtually no surface defects and no cracking due to excessive temperature difference, thus improving the quality of hot bending forming.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0026] This disclosure provides a curved glass processing device, which includes a forming module 20 and a non-forming module 10 arranged along a first horizontal direction. The forming module 20 is configured to heat the part of the flat glass to be formed to a softening temperature and realize the hot bending forming of the part to be formed. The non-forming module 10 is configured to clamp and support the non-forming part of the flat glass and heat the non-forming part to a buffer temperature below the softening temperature.

[0027] In existing technologies, although hot-bent glass only needs to be partially bent, it needs to be bent as a whole during the processing, and then the part that needs to be kept flat is flattened.

[0028] In this solution, forming module 20 and non-forming module 10 are respectively set for the areas that need to be bent and deformed and the areas that need to be kept flat. The non-forming module 10 can clamp and support the non-forming part of the flat glass, that is, the part that needs to be kept flat, while the forming module 20 can perform hot bending deformation on the forming part, that is, the part that needs to be bent.

[0029] The forming module 20 heats the forming portion to the softening temperature of the glass, ensuring that the glass can deform according to the shape of the mold. Specifically, the non-forming module 10 also heats the non-forming portion to a buffer temperature, which is lower than the softening temperature. This buffer temperature ensures that the non-forming portion has high hardness without softening, while also preventing excessive temperature differences between the forming and non-forming portions to avoid glass cracking. Because the non-forming portion is clamped and supported by the non-forming module 10, it will not undergo thermal bending deformation and will not develop defects under external forces.

[0030] In this solution, the non-formed module can support and heat the non-formed part, so that the non-formed part can remain in a flat state, with virtually no surface defects and no cracking due to excessive temperature difference, thus improving the quality of hot bending.

[0031] In some embodiments, the softening temperature is 580–680°C, and the buffer temperature is 400–520°C. The softening temperature can be selected and determined according to the type of glass to ensure that the glass softens and can be deformed at this temperature. The buffer temperature differs from the softening temperature to ensure that the non-formed parts do not soften.

[0032] In some embodiments, the non-formed module 10 includes a lower support plate 11, an upper support plate 12 located above the lower support plate 11, and a first telescopic cylinder 13. The lower support plate 11 has a flat support surface at the top, and the upper support plate 12 has a flat support surface at the bottom. The first telescopic cylinder 13 can drive the upper support plate 12 to move vertically relative to the lower support plate 11. The lower support plate 11 and the upper support plate 12 each have a flat support surface, which can clamp the non-formed portion of the flat glass, providing stable support and making the force more even, thus preventing surface defects under external force. The first telescopic cylinder 13 can be a cylinder, hydraulic cylinder, etc., connected to the upper support plate 12, and can drive the upper support plate 12 to move vertically. When it moves downward, it can press the upper support plate 12 onto the flat glass on the lower support plate 11.

[0033] In some embodiments, heating elements are provided in the upper support plate 12 and / or the lower support plate 11. Heating elements, such as electric heating wires, may be disposed inside the upper support plate 12 and the lower support plate 11.

[0034] In some embodiments, the curved glass processing equipment further includes a positioning insert 14, which can be driven to move onto and away from the lower support plate 11, and can also be driven to move towards the forming module 20 along the first horizontal direction to adjust the position of the flat glass on the lower support plate 11. The positioning insert 14 can be driven to move by a driving member, and can move onto or away from the support surface of the lower support plate 11. The positioning insert 14 can move towards the forming module 20 along the first horizontal direction to contact the edge of the flat glass on the lower support plate 11, so that the flat glass is moved to a suitable position, for example, such that the non-forming portion of the flat glass is located at the non-forming module 10, and the forming portion is located at the forming module 20.

[0035] In some embodiments, the non-forming module 10 may include multiple lower support plates 11 arranged along a first horizontal direction, multiple upper support plates 12 arranged along a first horizontal direction, and a corresponding multiple first telescopic cylinders 13. After the positioning insert 14 pushes the flat glass to the target position along the first horizontal direction, one or more upper support plates 12 closest to the forming module 20 can be driven to descend and press against the flat glass through the corresponding first telescopic cylinder 13 to achieve the initial positioning of the flat glass. Then, the positioning insert 14 is driven to leave the lower support plate 11, and other upper support plates 12 are driven to press against the flat glass through other first telescopic cylinders 13.

[0036] In some embodiments, the forming module 20 includes a hot bending template 21, a pressure plate 22 located above the hot bending template 21, and a second telescopic cylinder 23. The hot bending template 21 has a curved surface at its top. The second telescopic cylinder 23 can drive the pressure plate 22 to move vertically toward the hot bending template 21. The top of the hot bending template 21 is provided with a curved surface, which is a surface used to deform the forming part of the flat glass, so that the flat glass is deformed into a shape corresponding to the curved surface. The second telescopic cylinder 23 can drive the pressure plate 22 to move downward, so that the pressure plate 22 presses the flat glass against the curved surface to form the corresponding shape.

[0037] In some embodiments, the curved surface extends and bulges upward about a second horizontal axis, which is perpendicular to the first horizontal direction. The pressure plate 22 has a flat lower surface and is connected to the second telescopic cylinder 23 via a rotating mechanism. The rotating mechanism can drive the pressure plate 22 to rotate about an axis along the second horizontal direction. The curved surface is an upwardly bulging curved surface, the lower surface of the pressure plate 22 is a flat surface, and the rotating mechanism can drive the pressure plate 22 to rotate around the second telescopic cylinder 23. The second telescopic cylinder 23 drives the pressure plate 22 to descend and, in conjunction with the rotating mechanism, drives the pressure plate 22 to rotate, allowing the pressure plate 22 to press against different parts of the curved surface of the hot bending template 21. That is, the lower surface of the pressure plate 22 is tangent to the curved surface of the hot bending template 21 at different positions (with glass between them), thereby bending the flat glass. (Reference) Figure 2 and Figure 3 As shown, the pressure plate 22 is pressed against different positions of the hot bending template 21.

[0038] In some embodiments, the second telescopic cylinder 23 can be driven to move along the first horizontal direction, thereby causing the pressure plate 22 to move along the first horizontal direction. The second telescopic cylinder 23 can be driven to move along the first direction by a driving component such as a cylinder or hydraulic cylinder. The second telescopic cylinder 23 can also cause the pressure plate 22 to move along the first horizontal direction, so that the pressure plate 22 can be pressed against different positions of the hot bending template 21.

[0039] It is understood that the pressure plate 22 can move along the first horizontal direction, move along the vertical direction, and rotate around the axis of the second horizontal direction. These three movements cooperate with each other, so that the flat lower surface of the pressure plate 22 can be pressed against different positions of the bending surface of the hot bending template 21 to realize the hot bending forming of flat glass.

[0040] In some embodiments, heating elements are provided in the pressure plate 22 and / or the hot bending template 21. Heating elements, such as heating wires, may be provided inside the pressure plate 22 and the hot bending template 21.

[0041] In some embodiments, in the first horizontal direction, the height of the curved surface gradually decreases along the direction from the non-forming module 10 toward the forming module 20. The height of the curved surface of the hot bending template 21 near the end of the non-forming module 10 is the maximum height, which can be the same as the height of the lower support plate 11 to allow the flat glass to extend from the lower support plate 11 to the upper side of the curved surface. Additionally, the pressure plate 22 can be progressively pressed against various positions on the curved surface along the direction from the non-forming module 10 toward the forming module 20, causing the formed portion of the flat glass to progressively deform into a shape similar to the curved surface.

[0042] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0043] While specific embodiments of this disclosure have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of this disclosure. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this disclosure. In particular, as long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner.
