Technical Field
[0001] The utility model specifically relates to the technical field of glass hot bending curvature adjustment, in particular to a glass processing hot bending device with a curvature adjustment structure. Background Art
[0002] Heat-bent glass is a curved glass made by heating and softening flat glass, forming it in a mold, and then annealing it. Heat-bent glass is generally processed in an electric furnace. A continuous heat-bending furnace generally has 5-6 chambers and 11-13 workstations, and a finished product can be produced in about tens of minutes. An intermittent heat-bending furnace generally has only one chamber, and heating, forming, and annealing are all completed in one chamber. The processing cycle takes several hours to 10 to 20 hours, which is suitable for making small batches of extra-large heat-bent glass.
[0003] When traditional curved glass is hot-bent, two fixed molds are used to heat-press the glass to achieve the curvature of the glass. Although the curvature of the glass can be hot-bent, only one size of curvature can be hot-pressed. The curvature of the car windshield varies depending on the car model. Therefore, when processing the glass, the mold needs to be replaced frequently, which reduces work efficiency.

[0030] See also Figure 1-9 In the embodiment of the utility model, a glass processing hot bending device with a curvature adjustment structure includes a hot bending mold assembly 3; the hot bending mold assembly 3 includes a C-shaped curvature template 34; the bottom of the curvature template 34 is fixedly installed with a C-shaped frame 33 through a plurality of fixing plates 32; the bottom of the C-shaped frame 33 is connected to a telescopic rod 31; the telescopic rod 31 is movably installed on a second sleeve 30;

[0032] By adopting the above technical solution, during processing, the curvature of the curvature template 34 can be effectively adjusted by adjusting the second sleeve 30 and the telescopic rod 31 bracket, so that when hot bending different types of glass, the curvature of the curvature template 34 can be adjusted as needed. After the adjustment is completed, the curvature template 34 is fixed by the self-locking device between the second sleeve 30 and the telescopic rod 31, effectively preventing the curvature of the curvature template 34 from changing during the hot bending process of the glass.
[0033] Both ends of the plurality of support plates 22 are connected to the adjusting rod 21 through bearings; one end of the adjusting rod 21 away from the support plate 22 is movably installed in the first sleeve 20; and the first sleeve 20 is welded and fixed to the base 1.

[0035] By adopting the above technical solution, during hot bending, the glass is placed on the support plate 22, and the connecting plate 40 is driven downward by the driving device. When the connecting plate 40 moves downward, the pressure rod 41 contacts the glass, and the connecting plate 40 continues to press down. At this time, the pressure rod 41 opens a compression spring 42 through the glass, so that multiple pressure rods 41 form the same curvature as the curvature template 34, ensuring that the curvature of both sides of the glass is the same after the hot bending process is completed.
[0036] In this embodiment, the support plates 22 and the pressure rods 41 have the same width and are arranged alternately at intervals.

[0039] The working principle of the utility model is: during processing, the curvature of the curvature template 34 is effectively adjusted by adjusting the second sleeve 30 and the telescopic rod 31 bracket, so that when hot bending different types of glass, the curvature of the curvature template 34 can be adjusted as needed.

When the connecting plate 40 moves downward, the pressure rod 41 contacts the glass, and the connecting plate 40 continues to press downward. At this time, the pressure rod 41 opens a compression spring 42 through the glass, so that multiple pressure rods 41 form the same curvature as the curvature template 34, ensuring that the curvature of both sides of the glass is the same after the hot bending process is completed;
[0041] When hot bending is performed, the pressure rod 41 drives the glass to be pressed down, and the glass drives the support plate 22 to move downward. The arc groove 23 set at the bottom of the support plate 22 is effectively fitted with the surface of the arc template 34 to ensure that multiple support plates 22 form the same arc template 34. When the support plate 22 moves, the two ends of the support plate 22 press down the adjustment rod 21 to achieve the contraction of the adjustment rod 21 into the first sleeve 20, to ensure that the support plate 22 will not deviate when moving, thereby ensuring the efficiency and quality of the glass hot bending processing.
