[0031] In work, the cut middle control large screen to be hot bent is placed above the lower die seat 301, and the middle control large screen to be hot bent is uniformly heated to a temperature of about 550-650, and the middle control large screen will become a plastic state at the temperature, then the rotation shaft 2 and the mounting disc 3 are controlled to rotate, the mounting disc 3 drives one of the heated middle control large screens to rotate to the side close to the upper die seat 501, when the upper die seat 501 and the lower die seat 301 are in the same vertical plane, the rotation of the rotation shaft 2 is stopped, then the oil cylinder 5 is controlled to operate, the oil cylinder 5 drives the upper die seat 501 to move downwards, so that the upper die seat 501 is combined with the middle control large screen in the plastic state, under the mutual combination of the upper die seat 501 and the lower die seat 301, the middle control large screen can be hot bent into a required shape, after the hot bending is completed, the oil cylinder 5 drives the upper die seat 501 to move upwards, so that the upper die seat 501 is away from the lower die seat 301, then the rotation shaft 2 and the mounting disc 3 are controlled to rotate, so that the formed middle control large screen is rotated to the other side, and the subsequent middle control large screen is rotated to below the upper die seat 501 again, in this way, the middle control large screens can be continuously hot bent, and the cooling time of the middle control large screen after the hot bending is given, so that the problem that the middle control large screen needs to be cooled and taken out after the hot bending of one middle control large screen is completed, and then the hot bending of the next middle control large screen is performed, is solved, and the operation is more convenient.

[0032] The adjusting mechanism comprises L-shaped support plates 6 fixed to the side walls of the mounting disc 3, the L-shaped support plates 6 are provided in plurality and are one-to-one corresponding to the lower die seats 301, one side of the L-shaped support plate 6 away from the mounting disc 3 is fixedly connected with a gas cylinder 7, the telescopic end of the gas cylinder 7 is fixedly connected with a U-shaped frame 8, the end of the U-shaped frame 8 away from the gas cylinder 7 is fixedly connected with a sliding frame 801, and the end of the sliding frame 801 away from the U-shaped frame 8 is fixedly connected with a receiving template 9, and the hot bending of the middle control large screen can be realized through the combination of the upper die seat 501 and the receiving template 9.

[0033] In work, the middle control large screen to be hot bent is placed above the receiving template 9, when the receiving template 9 and the lower die seat 301 are rotated to below the upper die seat 501, if the receiving template 9 is not aligned with the upper die seat 501, that is, not in the same vertical plane, at this time, the telescopic end of the gas cylinder 7 is controlled to push the U-shaped frame 8 to move, the U-shaped frame 8 drives the sliding frame 801 to move, the sliding frame 801 drives the receiving template 9 to move, the receiving template 9 drives the middle control large screen to move, until the middle control large screen is in the same vertical plane with the upper die seat 501, in this way, the hot bending of the subsequent middle control large screen is facilitated, and different types of middle control large screens can be adjusted and hot bent, so the use range is wide.

[0034] A plurality of heating wires 901 are arranged in the inner part of the receiving template 9, and a plurality of grooves are arranged in the inner part of the receiving template 9 and matched with the heating wires 901; when the middle control large screen is heated to a plastic state and placed on the receiving template 9, the heating wires 901 are controlled to heat the receiving template 9, so that the heat bending temperature of the middle control large screen is maintained, and the heat bending of the middle control large screen is facilitated; after the heat bending, the heating of the heating wires 901 is stopped, and the middle control large screen is cooled gradually.

[0035] The fixed frame 10 is fixed to the side of the workbench 1 away from the connecting frame 4, the annular seat 11 is fixed to the upper part of the fixed frame 10, the column type plate 12 is fixed to the side wall of the annular seat 11, the electric push plate 121 is slidably connected in the column type plate 12, and the limiting plate 13 is fixed to the bottom of the electric push plate 121; when the heat bending and cooling of the middle control large screen are completed, the mounting disc 3 is controlled to rotate counterclockwise by one hundred and eighty degrees by the rotating shaft 2, so that the middle control large screen is rotated to the same vertical plane as the electric push plate 121, then the telescopic end of the air cylinder 7 is controlled to drive the U-shaped frame 8 to move, so that the U-shaped frame 8 drives the sliding frame 801 and the receiving template 9 to move, the receiving template 9 moves to the side close to the limiting plate 13, then the electric push plate 121 is controlled to move downward, so that the electric push plate 121 drives the limiting plate 13 to move downward, and the limiting plate 13 is arranged on the side of the middle control large screen, as shown in Figure 4 、 Figure 5 and Figure 7 , at this time, the receiving template 9 is located on the side away from the lower die seat 301, and the limiting plate 13 is located on the side wall of the middle control large screen, then the telescopic end of the air cylinder 7 and the U-shaped frame 8 are controlled to move in the opposite direction, the U-shaped frame 8 drives the sliding frame 801 and the receiving template 9 to move in the opposite direction, that is, to move to the side close to the lower die seat 301 again, at this time, the middle control large screen is blocked by the limiting plate 13, so the middle control large screen will not move with the receiving template 9, and thus the middle control large screen will slowly separate from the upper surface of the receiving template 9, when the middle control large screen separates from the receiving template 9, the formed middle control large screen can be taken out by the external clamping device.

[0036] In this way, the problem that the formed middle control large screen is too close to the receiving template 9 and is difficult to take out can be avoided, and the use of the middle control large screen is facilitated.

[0037] The height of the limiting plate 13 is greater than the height of the central control screen after hot bending. The side wall of the electric push plate 121 is provided with a sliding groove, and the limiting plate 13 is slidably connected in the sliding groove. During operation, the sliding groove is provided to facilitate the blocking of the limiting plate 13. When the formed central control screen is taken out, the electric push plate 121 and the limiting plate 13 are controlled to return to the initial position again, and the cylinder 7 is controlled to drive the U-shaped frame 8 to return to the initial position again. The initial position is the position where the receiving template 9 is located above the lower mold base 301.

[0038] A support frame plate 14 is fixedly connected to the lower mold base 301 at the corresponding position of the sliding frame 801. There are two support frame plates 14 on one side of each lower mold base 301, and they are symmetrically arranged relative to the lower mold base 301. A rectangular groove 15 is opened on the upper part of each support frame plate 14. The bottom of the sliding frame 801 is slidably connected to the rectangular groove 15 through a slider. During operation, since the sliding frame 801 is slidably connected to the upper part of the support frame plate 14, that is, slidably connected to the rectangular groove 15, the sliding frame 801 can move easily under the limitation of the rectangular groove 15, thereby facilitating the sliding frame 801 to drive the receiving template 9 to move back and forth, and facilitating its adjustment of the central control screen.

[0039] Each of the receiving templates 9 is rotatably connected to a plurality of rollers 16 at its bottom. Each roller 16 is in contact with the upper end face of the lower mold base 301. When the receiving template 9 moves, the receiving template 9 will drive the rollers 16 to roll above the lower mold base 301, thereby facilitating the adjustment of the central control screen and the subsequent removal of the formed central control screen.

[0040] The shape of the receiving template 9 is adapted to the shape of the upper mold base 501. Both the receiving template 9 and the upper mold base 501 are made of iron. The length of the receiving template 9 is greater than the length of the central control screen. During operation, the fact that both the receiving template 9 and the upper mold base 501 are made of iron can prevent the glass in the plastic state from sticking to the receiving template 9 and the upper mold base 501, thereby facilitating the hot bending of the central control screen.

[0041] A cooling seat 17 is slidably connected to one side of the workbench 1. The cooling seat 17 has a frame structure, and its height is greater than that of the receiving template 9. Cooling pipes are installed inside the cooling seat 17. The cooling seat 17 is connected to an external electric push column. During operation, when the central control screen after hot bending rotates 90 degrees counterclockwise with the installation plate 3, it rotates to the side of the cooling seat 17. At this time, the external electric push column is controlled to push the cooling seat 17 to move, so that the cooling seat 17 covers the receiving template 9. Then, by introducing external coolant into the cooling seat 17, the cooling seat 17 gradually cools the central control screen after hot bending, which facilitates its subsequent recycling.

[0042] The upper surface of the mounting plate 3 has a limiting groove, and the bottom of the cooling seat 17 is slidably connected in the limiting groove. The limiting groove allows the cooling seat 17 to cover the receiving template 9, thereby facilitating the cooling of the central control screen.

[0043] During operation, the pre-cut central control screen to be bent is placed above the lower mold base 301, and the screen is evenly heated to a temperature of approximately 550-650°C. At this temperature, the screen becomes viscoplastic. Then, the motor drives the rotating shaft 2 and the mounting plate 3 to rotate. The mounting plate 3 rotates one of the heated screens towards the side closer to the upper mold base 501. When the upper mold base 501 and the lower mold base 301 are on the same vertical plane, the rotation of the rotating shaft 2 is stopped. Then, the hydraulic cylinder 5 is operated, causing the upper mold base 501 to move downwards, allowing it to engage with the viscoplastic screen. With the combination of 301, the central control screen can be hot-bent into the required shape. After the hot bending is completed, the control cylinder 5 drives the upper mold base 501 to move upward, away from the lower mold base 301. Then, the control shaft 2 and the mounting plate 3 are rotated to rotate the formed central control screen to the other side. The subsequent central control screen will rotate again to the lower mold base 501. This design can continuously hot-bend multiple central control screens and also provides cooling time for the central control screen after hot bending. It solves the problem in the existing technology that after the hot bending of one central control screen, it is necessary to wait for it to cool down and be removed before the next central control screen can be hot-bent. The operation is more convenient.

[0044] The central control screen to be heat-bent is placed above the receiving template 9. When the receiving template 9 and the lower mold base 301 rotate to below the upper mold base 501, if the receiving template 9 is not aligned with the upper mold base 501, i.e., not on the same vertical plane, the telescopic end of the control cylinder 7 pushes the U-shaped frame 8 to move. The U-shaped frame 8 drives the sliding frame 801 to move, the sliding frame 801 drives the receiving template 9 to move, and the receiving template 9 drives the central control screen to move until the central control screen and the upper mold base 501 are on the same vertical plane. This design not only facilitates the subsequent heat bending of the central control screen, but also allows for the adjustment and heat bending of different types of central control screens, making it widely applicable.

[0045] After the central control screen has finished hot bending and cooling, the control rotating shaft 2 drives the mounting plate 3 to rotate counterclockwise by 180 degrees, so that the formed central control screen rotates to the same vertical plane as the electric push plate 121. Then, the control cylinder 7's telescopic end drives the U-shaped frame 8 to move, so that the U-shaped frame 8 drives the sliding frame 801 and the receiving template 9 to move. The receiving template 9 moves towards the side closer to the limiting plate 13. Then, the control electric push plate 121 moves downward, so that the electric push plate 121 drives the limiting plate 13 to move downward, so that the limiting plate 13 covers one side of the formed central control screen. Figure 4 ,Figure 5 and Figure 7 As shown, at this time, the receiving template 9 is located on the side away from the lower mold base 301, and the limiting plate 13 is located on the side wall of the formed central control screen. Then, the telescopic end of the control cylinder 7 and the U-shaped frame 8 move in opposite directions. The U-shaped frame 8 drives the sliding frame 801 and the receiving template 9 to move in opposite directions, that is, move again towards the side closer to the lower mold base 301. At this time, since the central control screen above the receiving template 9 is blocked by the limiting plate 13, the central control screen will not move with the receiving template 9. Therefore, the central control screen will slowly detach from the upper surface of the receiving template 9. When the central control screen detaches from the receiving template 9 to a certain extent, the formed central control screen can be taken out by the external clamping device.

[0046] This design avoids the problem of the formed central control screen being too close to the receiving template 9, making it difficult to remove, thus facilitating the subsequent use of the central control screen. Since the sliding frame 801 is slidably connected above the support frame plate 14, that is, slidably connected within the rectangular groove 15, the sliding frame 801 can move easily under the limitation of the rectangular groove 15, thereby facilitating the sliding frame 801 to drive the receiving template 9 to move back and forth, and facilitating the adjustment of the central control screen. After the central control screen is hot-bent, it rotates 90 degrees counterclockwise with the installation plate 3, that is, rotates to the side of the cooling seat 17. At this time, the external electric push column is controlled to push the cooling seat 17 to move, so that the cooling seat 17 covers the receiving template 9. Then, by introducing external coolant into the cooling seat 17, the cooling seat 17 gradually cools the hot-bent central control screen, facilitating its subsequent recycling.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
