Description

A segmented heating and forming device for anti-deformation large-arc transparent sheet materials Technical Field

[0001] This utility model relates to the technical field of segmented heating and forming devices, and in particular to a segmented heating and forming device for large-arc transparent sheet materials that is resistant to deformation. Background Technology

[0002] To address issues such as deformation, uneven stress, and decreased optical performance that easily occur during the thermoforming process of large-curvature transparent sheets, a segmented thermoforming device is used.

[0003] While existing segmented heating and forming devices have addressed some of the issues of uneven temperature control and high energy consumption inherent in traditional integral heating methods, the design of their heating modules still has significant limitations. Specifically, the heating modules in these devices often employ a fixed layout.

[0004] When processing sheet materials with dimensions much smaller than the maximum processing capacity of the equipment, the fixed-layout heating modules still need to heat the entire preset heating area, resulting in a large amount of heat being lost to non-processing areas, causing a great waste of energy. In addition, the segmented heating technology in the existing technology generally has fixed gears when adjusting the segment temperature, which results in a fixed temperature range during adjustment, which may cause large segment temperature errors, thus affecting the molding effect.

[0005] Based on this, a segmented heating and forming device for large-arc transparent sheet material with anti-deformation properties is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a segmented heating and forming device for anti-deformation large-arc transparent sheet metal, so as to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is: a segmented heating and forming device for anti-deformation large-arc transparent sheet metal, including a heating box, wherein a fixed platform is fixedly connected to the upper surface of the heating box, and further comprising;

[0008] The housing has multiple touch switches fixedly installed on its inner top wall. Multiple sliding rheostats are fixedly installed on one side of the heating box. Each of the multiple sliding rheostats has a sliding plate slidably connected to its surface. Two hydraulic rods, Hydraulic Rod 1 and Hydraulic Rod 2, are fixedly connected to the lower surface of the fixed platform. Connecting rods are fixedly connected to the extended ends of the two hydraulic rods and Hydraulic Rod 2. One end of each of the multiple connecting rods is fixedly connected to one side of the corresponding sliding plate. Top rods are fixedly connected to the surfaces of the multiple connecting rods. The multiple top rods are located below the multiple touch switches.

[0009] In some embodiments, the output ends of the two hydraulic rods are respectively fixedly connected to mounting boxes 1 and 2. Two sliders are fixedly connected to the opposite surfaces of the two mounting boxes 1. Two sliding grooves are opened on both sides of the mounting box 2. The inner walls of the two sliding grooves are slidably connected to the corresponding two sliders.

[0010] In some embodiments, two heating wires are fixedly installed on the inner walls of both mounting boxes 1 and 2.

[0011] In some embodiments, the housing has wire-passing grooves on both sides, and the heating box has multiple clearance grooves on one inner wall, with multiple connecting rods respectively disposed inside the corresponding multiple clearance grooves.

[0012] In some embodiments, a door is rotatably connected to one side of the heating chamber, and a heating mold is fixedly installed on the inner bottom wall of the heating chamber.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model uses the lifting and lowering of two hydraulic rods, namely, Hydraulic Rod 1 and Hydraulic Rod 2, to drive the lifting and lowering of Mounting Shell 1 and Mounting Shell 2. This allows for adjustment of the heating range according to the size of the plate on the heating mold. When Hydraulic Rod 1 lifts Mounting Shell 1, it can separate from Mounting Shell 2 under the action of the sliding groove and slider. The lifting of Hydraulic Rod 1 drives the connecting rod to rise synchronously. When the connecting rod rises to its highest point, the top rod on its surface will press and touch the switch, thereby shutting off the circuit of the heating wire and stopping the heating wire from heating. This allows for automatic start and stop of the heating wire's operation while adjusting the heating range, thus reducing energy consumption.

[0015] Secondly, this utility model uses hydraulic rod one or hydraulic rod two to drive mounting shell one and mounting shell two to rise. At the same time, the connecting rod drives the sliding plate to rise. At this time, the position of the sliding plate can adjust the resistance of the heating wire to the maximum through the sliding rheostat, so that the heating power is lower and the temperature is also lower. When it is necessary to gradually increase the temperature in stages, simply drive mounting shell one or mounting shell two to fall, which will gradually reduce the resistance of the heating wire and gradually increase the power. This can achieve linear segmented heating, thereby reducing the error of segmented heating temperature and improving the segmented heating effect. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved segmented heating and forming device for anti-deformation, large-arc transparent sheets. The technical solution of this utility model is as follows:

[0025] As shown in Figures 1-4, a segmented heating and forming device for anti-deformation large-arc transparent sheet includes a heating box 1, a fixed platform 4 is fixedly connected to the upper surface of the heating box 1, and also includes;

[0026] The housing 7 has multiple touch switches fixedly installed on its inner top wall. These touch switches are existing technology. By pressing the top rod 16, the current to the heating wire 12 can be switched on and off, thereby controlling the start and stop of the heating wire 12. Multiple sliding rheostats 14 are fixedly installed on one side of the heating box 1. Each sliding rheostat 14 has a sliding plate 15 slidably connected to its surface. Two hydraulic rods 1-5 and 2-6 are fixedly connected to the lower surface of the fixed platform 4. Each extended end of each hydraulic rod 1-5 and 2-6 has a connecting rod 13 fixedly connected to its surface. One end of each connecting rod 13 is fixedly connected to one side of a corresponding sliding plate 15. Each connecting rod 13 has a top rod 16 fixedly connected to its surface. The top rods 16 are located below the multiple touch switches.

[0027] As shown in Figure 2, in one embodiment, the output ends of the two hydraulic rods 5 and 6 are respectively fixedly connected to mounting boxes 8 and 9. Two sliders 11 are fixedly connected to the opposite surfaces of the two mounting boxes 8. Two sliding grooves 10 are opened on both sides of the mounting box 9. The inner walls of the two sliding grooves 10 are slidably connected to the corresponding two sliders 11. Through the setting of the sliders 11, the independent modular design between the mounting shell 1 and the mounting shell 2 can be realized, which facilitates the adjustment of the heating range and reduces energy consumption.

[0028] Two heating wires 12 are fixedly installed on the inner walls of both mounting boxes 8 and 9. The heating wires 12 are existing technology and can heat the board.

[0029] As shown in Figures 1 and 2, in one embodiment, wire grooves 17 are provided on both sides of the housing 7, and multiple clearance grooves are provided on one inner wall of the heating box 1. The wire grooves 17 facilitate the wiring of the sliding rheostat 14. Multiple connecting rods 13 are respectively arranged inside the corresponding multiple clearance grooves, and the clearance grooves can avoid the sliding of the connecting rods 13.

[0030] A door 2 is rotatably connected to one side of the heating box 1, and a heating mold 3 is fixedly installed on the inner bottom wall of the heating box 1.

[0031] The specific working method is as follows: When in use, first place the transparent sheet to be used on the heating mold 3, and at the same time turn on the heating wire 12 switch. This allows the heating wire 12 inside the first and second mounting shells to heat the transparent sheet. Under the action of the heating mold 3, the heated and softened transparent sheet will adhere to the heating mold 3 to achieve the curvature design of the sheet. By raising and lowering the two hydraulic rods 5 and 6, the first and second mounting shells can be raised and lowered, so that the heating range can be adjusted according to the size of the sheet on the heating mold 3. When the first hydraulic rod 5 raises the first mounting shell, it can be separated from the second mounting shell under the action of the slide groove 10 and the slider 11. The rise of the first hydraulic rod 5 drives the connecting rod 13 to rise synchronously. When the connecting rod 13 rises to the highest point, the top rod 16 on its surface will press and touch the switch, thereby turning off the circuit of the heating wire 12 and stopping the heating wire 12 from heating. This allows the heating wire 12 to be automatically started and stopped while adjusting the heating range, thus reducing energy consumption.

[0032] During segmented heating, hydraulic rod 5 or hydraulic rod 6 first drives mounting shell 1 and mounting shell 2 to rise. At the same time, connecting rod 13 drives sliding plate 15 to rise. At this time, the position of sliding plate 15 can adjust the resistance of heating wire 12 to the maximum through sliding rheostat 14, so that the heating power is smaller and the temperature is lower. When it is necessary to gradually increase the temperature in segments, simply drive mounting shell 1 or mounting shell 2 to fall, which will gradually reduce the resistance of heating wire 12 and thus gradually increase the power. This can achieve linear segmented heating, thereby reducing the error of segmented heating temperature and improving the segmented heating effect.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
