Each pair of second rotating shafts is connected to each other through a cooling water tank. A cooling fan is arranged at the bottom of the cooling water tank.

[0004] This device cannot achieve uniform cooling of curved glass to improve product yield. Utility Model Content

[0005] The purpose of this invention is to provide a curved glass cooling and forming device that can achieve uniform cooling of curved glass to improve product yield.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a curved glass cooling and forming device, including a base plate, a cooling device provided on the base plate, and the curved glass placed on top of the cooling device.

[0007] The cooling device includes a heating plate, and the heating plate is provided with heating wires.

[0008] A side plate is connected to one side of the base plate, and a first mounting hole is provided on the side plate; a second mounting hole is provided at the end of the heating plate; one end of the heating wire is placed in the first mounting hole, and the other end of the heating wire is placed in the second mounting hole.

[0009] The side plate is provided with a pressure plate, and the heating wire is provided with a locking block at one end near the side plate. The pressure plate is provided with a locking groove that cooperates with the locking block.

[0010] The heating plate is provided with a cover plate on top.

[0011] The top of the cover plate is provided with a mold, and the curved glass is placed in the mold.

[0012] A molding plate is provided above the mold.

[0013] The mold has a door on one side.

[0014] A pad is provided between the heating plate and the base plate.

[0015] A hydraulic rod is connected to the top of the molding plate; the locking block has a circular structure, and the locking groove is located at the bottom of the molding plate.

[0016] The beneficial effects of this application are as follows:

[0017] After the curved glass undergoes the heating and molding process, it is in a high-temperature state and needs to be cooled down. If the curved glass is directly cooled by circulating water, its process temperature will change suddenly, causing surface problems such as cracks and pitting, as well as glass springback, resulting in the curved glass not meeting the curvature requirements.

[0018] The cooling device can set the heating temperature, and the set temperature of the cooling device decreases sequentially; the high-temperature curved glass after molding is placed on the cooling device to achieve gradient and uniform cooling of the curved glass; the temperature of the curved glass is reduced uniformly, reducing or eliminating the internal stress after glass molding, and solving or reducing the problem of unqualified curvature of the curved glass caused by glass rebound.

[0019] The cooling device includes heating wires installed on the heating plate; the curved glass is placed on top of the heating plate; the heating plate is heated to a suitable temperature lower than that of the curved glass by the heating wires, and then the heating temperature is gradually reduced. This achieves gradient and uniform cooling of the curved glass, which can avoid large temperature differences of the curved glass in a short period of time and effectively improve product yield.

[0020] The curved glass is placed in a mold, and a molding plate is provided above the mold. This plate can maintain pressure on the curved glass during cooling, effectively preventing the curved glass from deforming due to temperature drop.

[0021] This curved glass cooling and forming apparatus is equipped with a cooling device that can adjust the temperature. The temperature of the cooling device is set to be lower than the temperature of the curved glass. The high-temperature curved glass after molding is placed on the cooling device. When the temperature of the curved glass drops to the set temperature, the set temperature is then gradually reduced. This achieves gradient and uniform cooling of the curved glass, reducing or eliminating the internal stress after molding, and solving or reducing the problem of unqualified curvature of the curved glass caused by glass springback.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.

[0028] Figure 1 The curved glass cooling and forming apparatus shown includes a base plate 9, on which a cooling device is provided, and the curved glass is placed on top of the cooling device.

[0029] The cooling device can regulate the temperature. The temperature of the cooling device can be set lower than the temperature of the curved glass. The high-temperature curved glass after molding is placed on the cooling device. When the temperature of the curved glass drops to the set temperature, the set temperature is then gradually reduced. This can achieve gradient and uniform cooling of the curved glass, reduce or eliminate the internal stress after molding, and solve or reduce the problem of non-compliant curvature of the curved glass caused by glass springback.

[0030] The cooling device includes a heating plate 6, on which a heating wire 3 is mounted. The heating wire 3 is installed on the heating plate 6; the heating wire 3 can heat the heating plate 6 to a suitable temperature lower than that of the curved glass. When the temperature of the curved glass drops to the set temperature, the set temperature of the heating plate 6 is gradually reduced, thus achieving gradient and uniform cooling of the curved glass.

[0031] A side plate 12 is connected to one side of the base plate 9, and the side plate 12 has a first mounting hole 10; the end of the heating plate 6 has a second mounting hole 11; one end of the heating wire 3 is placed in the first mounting hole 10, and the other end of the heating wire 3 is placed in the second mounting hole 11. By passing one end of the heating wire 3 through the first mounting hole 10 on the side plate 12 and then extending it into the second mounting hole 11 on the heating plate 6, the heating wire 3 can be installed on the heating plate 6; this simplifies the disassembly and assembly of the heating wire 3 on the heating plate 6 and facilitates the replacement and maintenance of the heating wire 3.

[0032] A pressure plate 8 is provided on the side plate 12, and a locking block 13 is provided on one end of the heating wire 3 near the side plate 12. The pressure plate 8 has a locking groove that cooperates with the locking block 13. The pressure plate 8 is connected to the side plate 12 by bolts. Through the cooperation of the locking groove and the locking block 13, the pressure plate 8 fixes the end of the heating wire 3 to the side plate 12, which can effectively prevent the heating wire 3 from falling off the device. The device has multiple heating wires 3, and the pressure plate 8 can fix all the heating wires 3 at the same time.

[0033] The top of the heating plate 6 is provided with a cover plate 5. The cover plate 5 separates the heating plate 6, the heating wire 3 and the curved glass; it can provide support for the curved glass while making it heat more evenly, effectively avoiding large local temperature differences in the curved glass, which could damage the product surface or structure.

[0034] The top of the cover plate 5 is equipped with a mold 2, and the curved glass is placed in the mold 2. After the curved glass has undergone the heating and molding process, it is loaded into the mold 2 and enters the device together for cooling; the mold 2 can effectively prevent the curved glass from changing shape during cooling.

[0035] A molding plate 4 is provided above the mold 2. The mold 2 is a cuboid structure with an open top; the curved glass is placed in the mold 2; the molding plate 4 corresponds to the top opening of the mold 2. Before the mold 2 containing the curved glass is cooled, the molding plate 4 is pre-positioned at a suitable height above the mold 2. When the mold 2 containing the curved glass is cooled, the molding plate 4 presses against the top of the mold 2; this can effectively prevent the top of the curved glass from changing shape during cooling.

[0036] A door 1 is provided on one side of the mold 2. After the curved glass has undergone the heating and molding process, it can be opened through the door 1 and enter the interior of the device, where it is placed on the cover plate 5 for cooling. When cooling begins, the door 1 is closed to prevent large temperature differences between the inside and outside of the device from affecting the product.

[0037] A pad 7 is provided between the heating plate 6 and the base plate 9. The pad 7 has a cylindrical structure; multiple sets of pads 7 are provided at the bottom of the heating plate 6, which have strong load-bearing capacity and can provide stable support to ensure the normal operation of the cooling work.

[0038] A hydraulic rod is connected to the top of the molding plate 4; the locking block 13 has a circular structure and a slot is located at the bottom of the pressure plate 8. The hydraulic rod can flexibly drive the molding plate 4 to move up and down and can realize the pressing operation of the molding plate 4 on the top of the curved glass. The locking block 13 extends outward along the edge of the heating wire 3; the slot is located on the pressure plate 8 to facilitate the disassembly of the heating wire 3.

[0039] The specific workflow of this utility model is as follows:

[0040] Curved glass is loaded into mold 2. After the heating and molding process, door 1 is opened, and mold 2 is pushed to the corresponding position on cover plate 5. Door 1 is then closed. Heating wire 3 is installed between cover plate 5 and heating plate 6, and the heating wire 3 is maintained at a pre-set temperature. Molding plate 4 is pre-set at a suitable height above mold 2. When mold 2 containing curved glass is cooled, molding plate 4 presses firmly against the top of mold 2. Heating wire 3 heats heating plate 6 to a temperature lower than that of mold 2. When the temperature of curved glass drops to the set temperature, the set temperature of heating plate 6 is gradually reduced, thus achieving gradient and uniform cooling of the curved glass. After the corresponding cooling time is reached, mold 2 is pushed to the next station for final circulating water cooling.
