[0002] During the hot-bending glass processing, 2D glass is usually placed in a graphite mold and heated. The softened glass is deformed according to the shape of the hot-bending mold and eventually becomes 3D glass.

[0003] When the glass size is large, since large-sized graphite molds are difficult to process and are heavy and difficult to carry, multiple graphite molds are usually spliced ​​together to form a whole lower mold. Since there are gaps between adjacent graphite molds, during the hot bending process, some gas rises along the gaps as the temperature rises, and it is easy to form bulges at the edge of the glass, resulting in poor product quality.

[0004] In the prior art, an upper mold having the same shape as the upper surface of the glass is usually used to press the glass downward so that the glass to be processed fits the mold completely, thereby ensuring the quality of the glass product. However, this method has a large upper mold mass, is not easy to operate, and is not suitable for bending different types of glass, such as CN218879715U. Utility Model Content

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] like Figures 1 to 3 As shown, the large-size hot-bending glass bending tool disclosed in the first embodiment of the present application includes a mounting frame assembly 10 and a bending assembly 20. The mounting frame assembly 10 includes a mounting frame structure 11 and an adjusting structure 12. The adjusting structure 12 is movably connected to the mounting frame structure 11. The mounting frame structure 11 includes a plurality of adjusting structures 12 and the mounting frame structures 11 are arranged one-to-one. The bending assembly 20 is connected to the adjusting structure 12. The bending assembly 20 and the adjusting structure 12 are arranged one-to-one. The plurality of bending assemblies 20 are arranged corresponding to the splicing seams of the hot bending lower mold.

[0032] The technical solution of the first embodiment is applied, and the position of the adjusting structure on the mounting frame structure is adjusted according to the size of the glass to be processed, so that the bending assembly is arranged corresponding to the edge of the lower mold joint, and the glass is placed on the lower mold, and the bending assembly is placed on the glass. As the temperature rises, the glass continues to soften, and the glass corresponding to the position of the lower mold joint is not prone to bulging under the action of the gravity of the bending assembly, and the surface quality of the glass is good. The bending assembly is arranged at a position where the glass is prone to surface defects, which reduces the volume of the bending assembly and thus reduces the mass of the bending assembly. The position of the bending assembly can be adjusted by the adjusting structure, so that it is suitable for hot bending of glass of different sizes. The technical solution of the first embodiment effectively solves the problem in the prior art that when bending large-sized cover glass, the bending tool is heavy and difficult to operate and has poor versatility.

[0033] like Figures 1 to 3As shown, in the technical solution of the first embodiment, the adjustment structure 12 includes a first connection part 121 and a second connection part 122, the first connection part 121 and the second connection part 122 are movably connected, the first connection part 121 is movably connected to the mounting frame structure 11, and the second connection part 122 is connected to the bending assembly 20. The lower mold is a concave mold, that is, a structure with a low middle and high surroundings. Therefore, when the temperature rises, the air at the joint expands due to heat and rises along the joint. A large amount of air accumulates at the end of the joint with a higher height. These positions are prone to poor quality phenomena such as bulging. The bending assembly 20 is arranged corresponding to the place where the air accumulates more, which is conducive to the discharge of air along the gap. The relative position of the first connection part 121 and the mounting frame structure 11 changes, thereby changing the position of the bending assembly 20. By adjusting the positions of multiple bending assemblies 20, it can be applied to glass bending of different sizes. The first connection part 121 is movably connected to the second connection part 122, so the height of each press-bending component 20 in the vertical direction can be changed according to the needs. For example, in some cases, the lower mold is composed of two molds, so two press-bending components are selected. In some cases, the lower mold is composed of four molds, so four press-bending components are selected.

[0034] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the first connection part 121 is sleeved on the mounting frame structure 11, and the first connection part 121 has a threaded hole, which is arranged on the side wall of the first connection part 121, and a first fastener is inserted into the threaded hole. The first fastener is loosened to adjust the position of the first connection part 121 relative to the mounting frame structure, and then the bending assembly 20 is adjusted to a suitable position. The adjustment structure 12 is fixed by tightening the first fastener, so as to avoid the position change of the bending assembly 20 during the bending process affecting the surface quality of the glass.

[0035] like Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the mounting frame structure 11 includes a first mounting frame 111, a second mounting frame 112 and a fixing portion 113. The first mounting frame 111 includes two, the first ends of the two first mounting frames 111 are connected to the fixing portion 113, and the two first mounting frames 111 are located on the same straight line. The second mounting frame 112 includes two, the two second mounting frames 112 are connected to the fixing portion 113, and the two second mounting frames 112 are located on the same straight line. The first mounting frame 111 and the second mounting frame 112 are perpendicular to each other. When hot bending large-sized glass, the lower mold is usually spliced ​​by two or four small molds, so two or four bending assemblies 20 are required, so two first mounting frames 111 and two second mounting frames 112 are set to meet the needs. The first mounting frame 111 and the second mounting frame 112 are both connected to the fixing portion 113, and the fixing portion 113 can be selected to have a circular or triangular structure to ensure the stability of the connection. In addition, the fixing portion 113 is connected to a circular ring, and during operation, a steel pipe or the like can be passed through the circular ring to lift or lower the entire bending tool.

[0036] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the mounting frame structure 11 further includes a first limiting segment 114 and a second limiting segment 115, the first limiting segment 114 is connected to the second end of the first mounting frame 111, and the second limiting segment 115 is connected to the second end of the second mounting frame 112. The provision of the first limiting segment 114 and the second limiting segment 115 prevents the adjustment structure 12 from falling off from the mounting frame structure 11, resulting in structural failure.

[0037] like Figure 3 As shown, in the technical solution of the first embodiment, the first connection part 121 has a long hole 1211, a second fastener is provided between the second connection part 122 and the long hole 1211, and the bending assembly 20 is connected to the end of the second connection part 122 away from the first connection part 121. When the second fastener is loosened, the second connection part 122 can move along the long hole 1211, so as to adjust the height of the bending assembly 20 in the vertical direction. When the lower mold is formed by splicing two molds, only two bending assemblies 20 are needed, and the heights of the other two bending assemblies 20 are adjusted to avoid contact with the glass.

[0038] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the bending assembly 20 is made of graphite. Graphite has good high temperature resistance and can work stably in a high temperature environment. Graphite has good lubricity and glass is not easy to adhere to graphite.

[0039] like Figures 1 to 3As shown, in the technical solution of the first embodiment, the bending assembly 20 has a threaded hole, and the bending assembly 20 and the adjustment structure 12 are connected by bolts, wherein the threaded hole is a blind hole, thereby preventing the bolt from contacting the glass and affecting the surface quality of the glass. The second connecting portion 122 also includes a triangular rib plate, thereby improving the strength of the entire second connecting portion 122 and preventing it from breaking.

[0040] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the height of the bending assembly 20 in the vertical direction is 0.9 to 1.2 times of the glass to be processed. The length of the bending assembly 20 perpendicular to the side of the corresponding mounting frame structure 11 is 500mm to 1000mm, and the length of the side of the bending assembly 20 parallel to the corresponding mounting frame structure 11 is 50mm to 100mm. The bending assembly 20 of this size has a certain surface area while completely covering the area prone to bubbling, thereby avoiding the glass surface from being subjected to high pressure and resulting in poor surface quality. The height of the bending assembly 20 in the vertical direction is the thickness of the bending assembly 20. When the thickness of the bending assembly 20 is less than 0.9 times of the glass to be processed, the mass of the bending assembly 20 is small and the air discharge is not utilized; when the thickness of the bending assembly 20 is greater than 1.2 times of the glass to be processed, the mass of the bending assembly 20 is large, and it is easy to produce marks on the upper surface of the glass, affecting the surface quality of the glass.

[0041] The difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the bending assembly 20 has a contour surface consistent with the shape of the hot bending lower mold, and the contour surface is arranged away from the mounting frame assembly 10. The arrangement of the contour surface further ensures that the bending assembly 20 is arranged in close contact with the glass, and the gas exhaust effect is better.

[0042] In summary, the present application relates to the hot bending forming process of the cover glass. Specifically, a new type of concave mold forming mold is provided, which can effectively reduce the pressure of operators to lift the whole graphite concave mold, reduce labor and save the labor cost of the enterprise; at the same time, it is suitable for various sizes, saving the cost of mold materials. The above-mentioned bending tool (large-size hot-bending glass bending tool) is mainly composed of high-temperature resistant stainless steel hollow tubes, stainless steel sheets, iron rings, graphite sheets, etc., which can realize hot bending glass forming. The above-mentioned bending tool can adjust the position of four graphite pieces through the iron ring connector to achieve the bending of glass of various specifications, sizes and shapes. The above-mentioned bending tool can reduce the time for the operator to carry the whole graphite concave mold, reduce the workload of the operator, achieve the effect of two-person transportation and bending the upper mold, reduce the labor cost of the enterprise, and reduce the pressure on the operator to lift the whole upper mold. At the same time, this bending tool can adjust the thickness of the four graphite sheets and adjust the overall weight to cope with the pressure required for glass of different thicknesses. The bent glass of the bending tool of the present application can be glass of various specifications and sizes, glass of different shapes, generally rectangular glass, mainly for 3D glass hot bending molding. The overall material of the bending tool is mainly high-temperature resistant stainless steel hollow tube (mounting frame structure 11). The high-temperature resistant stainless steel hollow tube is made of 304 steel. The hollowness is to reduce the weight. It is non-toxic and pollution-free, wear-resistant and high-temperature resistant, and has no odor. It should be pointed out that the weight of the bending tool can be changed at any time, and the weight is determined by four graphite sheets (bending components 20). Just prepare 4 iron rings (adjustment structure 12), and the diameter of the iron ring can be a few wires larger than the diameter of the hollow tube, so that the iron ring can move on the hollow tube. The large iron ring is placed vertically on the high-temperature resistant stainless steel hollow ring (fixing part 113), and the contact surface is welded firmly. The hollow tubes are respectively welded on the four sides of the hollow ring in a cross shape. The diameter of the round iron sheet (the first limiting section 114 and the second limiting section 115) is larger than the inner diameter of the iron ring, and is welded to the outermost edge of the hollow tube to prevent the four iron rings from slipping off the hollow tube. The graphite sheet and the hollow tube are fixed with nuts, and a hole is punched in the middle of the graphite sheet. Screws are welded on the joint of the hollow tube, passed through the hole in the middle of the graphite sheet, and fixed with nuts. It should be pointed out that the large iron ring needs to be larger so that the pipe lifting and bending tool can be inserted later. There is no need to reduce the temperature of the heating furnace to the lowest level. It can be operated with temperature, which reduces the processing time of a single piece and increases efficiency.
