In order to meet the needs of customers, glass is often subjected to hot bending treatment during the processing. When the glass is hot bent, the maximum hot bending temperature of the glass is 580 degrees Celsius to avoid the generation of corrugations after the hot bending of the glass.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] A hot bending device for glass processing, including a device body 1, an electric telescopic rod 2 is fixedly connected to the top of the device body 1, a hot pressing plate 3 is fixedly connected to the bottom of the electric telescopic rod 2, two groups of heat dissipation structures 4 are arranged on both sides of the device body 1, the heat dissipation structure 4 includes a heat dissipation window 41, a fan 42 is fixedly connected inside the heat dissipation window 41, the surface of the heat dissipation window 41 is threadedly connected with a fixing bolt 43, and a dust-proof net 44 is installed on the surface of the heat dissipation window 41 through the fixing bolt 43. A cavity is opened at the bottom of the device body 1, and an adjusting structure 7 is movably connected inside the cavity. The adjusting structure 7 includes a threaded rod 71, a turning handle 72 is fixedly connected to one end of the threaded rod 71, a slider 73 is movably connected to the surface of the threaded rod 71, a sliding plate 74 is fixedly connected to the bottom of the slider 73, a plug rod 75 is inserted into the sliding plate 74, a limiting disk 76 is fixedly connected to one end of the plug rod 75, a spring 77 is fixedly connected to the surface of the limiting disk 76, a pulley 78 is fixedly connected to the surface of the limiting disk 76, a placing plate 79 is fixedly connected to the top of the sliding plate 74, a plug block 6 is inserted into the placing plate 79, and a lower mold 5 is fixedly connected to the top of the plug block 6. The adjusting structure 7 is provided. After inserting the plug block 6 of the lower mold 5 into the adjusting structure 7 through the placing plate 79, turning the turning handle 72 drives the threaded rod 71 to rotate, so that the slider 73 moves on the threaded rod 71, driving the sliding plate 74 to move in the trapezoidal cavity. The pulleys 78 at both left and right ends of the sliding plate 74 drive the plug rod 75 to move into the plug block 6 as the hypotenuse of the trapezoidal cavity becomes narrower. The plug rod 75 is inserted into the plug block 6 to lock the lower mold 5, completing the installation of the lower mold 5. Reverse operation can disassemble the lower mold 5, making the operation of replacing the mold of this hot bending device simple. The mold can be replaced as needed to produce glass with different curvatures. Two groups of heat dissipation structures 4 are provided. The rotation directions of the fans 42 in the two groups of heat dissipation structures 4 are the same. One group blows air into the device, and the other group blows the hot air inside the device outwards, which can quickly cool the processed glass, reduce the waiting time between two processes, and improve the processing efficiency. The dust-proof net 44 is installed outside the heat dissipation window 41 through the fixing bolt 43 to prevent external dust from entering the device during heat dissipation and affecting the production quality. Installing through bolts also facilitates the disassembly and cleaning of the dust-proof net 44.

[0024] Further, the output end of the electric telescopic rod 2 penetrates through the top of the device body 1 and is fixedly connected to the hot pressing plate 3. When the electric telescopic rod 2 extends, it drives the hot pressing plate 3 to move downward to hot press the glass.

[0025] Further, heat dissipation windows 41 are opened on both sides of the device body 1. The two groups of heat dissipation structures 4 are symmetrically arranged. The dust-proof net 44 is installed on the outer surface of the heat dissipation window 41. The rotation directions of the two groups of fans 42 are the same. One group blows air into the device, and the other group blows the hot air inside the device outwards. The dust-proof net 44 prevents external dust from entering the device during heat dissipation and affecting the production quality. Installing through bolts also facilitates the disassembly and cleaning of the dust-proof net 44.

[0026] Further, the cavity is trapezoidal, and the pulley 78 contacts the hypotenuse of the trapezoidal cavity. The movement of the insert rod 75 is driven by the extrusion of the hypotenuse on the pulley 78.

[0027] Further, the slider 73 is movably connected to the surface of the threaded rod 71 through the internal threaded groove. The radius of the limit disc 76 is greater than the radius of the insert rod 75, and the limit disc 76 limits the moving distance of the insert rod 75.

[0028] Further, one end of the spring 77 is fixedly connected to the surface of the sliding plate 74, and the other end of the spring 77 is fixedly connected to one end surface of the limit disc 76. The other end of the limit disc 76 is fixedly connected to the pulley 78. While the sliding plate 74 moves with the slider 73 on the threaded rod 71, it drives the pulley 78 to move. During the movement of the pulley 78, it is extruded by the hypotenuse of the trapezoidal cavity, compressing the spring 77 and at the same time driving the insert rod 75 to move towards the center of the adjusting structure 7.

[0029] Further, the sliding plate 74 is C-shaped. The two insert rods 75 respectively penetrate through the two ends of the C-shape of the sliding plate 74 and are inserted into the two inserts 6 respectively. The insert 6 penetrates through the placing plate 79 and contacts the surface of the sliding plate 74 in the cavity. The pulley 78 drives the insert rod 75 to move towards the center of the adjusting structure 7 until the insert rod 75 is inserted into the insert 6, locking the lower mold 5.

[0030] Working principle: A hatch is installed on the surface of the device. When in use, first insert the insert 6 of the lower mold 5 into the adjusting structure 7 through the placing plate 79, then rotate the turning handle 72 to drive the threaded rod 71 to rotate, so that the slider 73 moves on the threaded rod 71, driving the sliding plate 74 to move in the trapezoidal cavity. The pulleys 78 at the left and right ends of the sliding plate 74 drive the insert rod 75 to move into the insert 6 as the hypotenuse of the trapezoidal cavity becomes narrower. At this time, the spring 77 is compressed, and the insert rod 75 is inserted into the insert 6 to lock the lower mold 5, completing the installation of the lower mold 5. Place the glass on the surface of the lower mold 5, and drive the hot pressing plate 3 to move downward by the elongation of the electric telescopic rod 2 to hot press the glass. After hot pressing, turn on the fan 42. One group blows air into the device, and the other group blows the hot air inside the device outwards to cool the processed glass. The dust-proof net 44 prevents external dust from entering the device during heat dissipation and affecting the production quality. The bolt installation also facilitates the disassembly and cleaning of the dust-proof net 44. When the mold needs to be replaced, rotate the turning handle 72 in the reverse direction, so that the slider 73 drives the sliding plate 74 to move in the reverse direction. At this time, the spring 77 elongates, driving the insert rod 75 to leave the insert 6, unlocking the lower mold 5.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive.
