Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a high-strength tempered glass bending and forming equipment. Background Technology

[0002] There are two main methods for bending tempered glass. One method involves placing the tempered glass blank on a mold, heating it to soften it, and then bending it to fit the curvature of the mold under the influence of gravity. After natural cooling, the hot bending operation is completed. The other method involves heating the tempered glass blank and bending it into a specified curvature using a pressure mold. Then, it is quickly and evenly cooled with cold air to complete the bending process. Bending tempered glass is stronger than hot bending. At the same thickness, the strength of bent tempered glass is three to five times that of hot-bent glass. Therefore, high-strength bent tempered glass is mainly made through the bending process.

[0003] A high-precision curved tempered glass forming system, application number 202420986687.X, includes a worktable body, a moving mechanism, a forming mechanism, and a mold mechanism. A high-temperature chamber is installed at one end of the worktable body, the moving mechanism at another end, a sliding groove at one end of the worktable body, the forming mechanism at the other end of the sliding groove, the mold mechanism at the other end of the moving mechanism, a cooling box at one end of the worktable body, and a side sealing door at the other end of the cooling box. This invention, through the worktable body and mold mechanism, allows the installation of concave templates for the desired tempered glass specifications onto a support platform via mounting rods, and the installation of convex templates for forming onto a lower pressure plate via the mounting rods. The concave and convex templates can be replaced according to production needs, improving the accuracy and adaptability of the device in processing curved tempered glass.

[0004] This technical solution requires removing the tempered glass from the heating zone when bending the tempered glass blank, and then hot-pressing it into the cooling zone. The tempered glass blank is exposed to the outside, and due to the large temperature difference, the heat of the tempered glass is quickly dissipated to the outside, resulting in a lot of heat waste and the risk of burns to nearby workers due to the high temperature air. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-strength tempered glass bending and forming equipment to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength tempered glass bending and forming device, comprising a base and a shell, characterized in that: a cooling chamber, a heating chamber and a preheating chamber are respectively arranged inside the shell from left to right; a preheating fan is installed on one side of the top of the shell, and the air inlet of the preheating fan is connected to a heat insulation sleeve through a heat insulation confluence pipe; a heat-conducting seat is fixed inside the heat insulation sleeve, and a communicating cavity is opened inside the heat-conducting seat; heat dissipation fins are fixed on the outer surface of the heat-conducting seat; and a heat insulation diversion pipe is connected to one side of the heat insulation sleeve.

[0007] By adopting the above technical solution, after the preheating fan starts, the waste heat air generated from cooling the tempered glass blank in the cooling chamber is sent into the heat-conducting seat through the heat-insulating diversion pipe. The waste heat air enters the heat-insulating confluence pipe through the connecting cavity and then enters the preheating fan to be discharged. At the same time, the heat-insulating confluence pipe, heat-insulating sleeve and heat-insulating diversion pipe reduce the exchange of temperature between the waste heat air and the outside, so that most of the heat can be dissipated into the preheating chamber through the heat-conducting seat and heat dissipation fins, thereby improving the utilization rate of heat resources. While the waste heat air circulates in the connecting cavity, the heat of the waste heat air is transferred to the heat dissipation fins through the heat-conducting seat. The serpentine shape of the connecting cavity can prolong the circulation time of the waste heat air, so that the heat-conducting seat can absorb more heat. Then, the heat is dissipated into the preheating chamber through the heat dissipation fins, so that the preheating chamber is heated to facilitate the preheating of the tempered glass blank and reduce the energy consumption of the heater.

[0008] Furthermore, the cooling chamber, heating chamber, and preheating chamber are interconnected, and a first cylinder is installed above the inside of the outer shell, with a sealing door connected to the output end of the first cylinder.

[0009] By adopting the above technical solution, after heating and cooling are completed, the first cylinder drives the sealing door to move upward, so that the cooling chamber, heating chamber, preheating chamber and the outside world are interconnected.

[0010] Furthermore, the heat-conducting base is made of copper, and the heat dissipation fins are made of aluminum alloy.

[0011] By adopting the above technical solution, the heat of the waste air is transferred to the heat dissipation fins through the heat conduction seat, and then the heat is dissipated to the preheating chamber through the heat dissipation fins, so that the preheating chamber is heated up to facilitate the preheating of the subsequent tempered glass blank.

[0012] Furthermore, the heat dissipation fins are provided in multiple quantities, and the multiple heat dissipation fins are distributed at equal intervals.

[0013] By adopting the above technical solution, the heat dissipation area is increased by increasing the number of heat dissipation fins, which facilitates the rapid release of heat from the waste air into the preheating chamber.

[0014] Furthermore, there are two of each of the heat insulation sleeve, heat conduction seat, and connecting cavity, and the multiple heat dissipation fins are divided into two groups. The two heat insulation sleeves, heat conduction seats, and connecting cavities are mirror-distributed, and the two groups of heat dissipation fins are symmetrically distributed.

[0015] By adopting the above technical solution, after the fan starts, the waste heat air generated by cooling the tempered glass blank in the cooling chamber is sent into the heat-conducting seat through the heat-insulated diversion pipe. The waste heat air enters the heat-insulated confluence pipe through the connecting cavity and then enters the preheating fan to be discharged. While the waste heat air is circulating in the connecting cavity, the heat of the waste heat air is transferred to the heat dissipation fins through the heat-conducting seat. Then, the heat is dissipated into the preheating chamber through the heat dissipation fins, so that the preheating chamber is heated up to facilitate the preheating of the subsequent tempered glass blank.

[0016] Furthermore, the connecting cavity is serpentine in shape.

[0017] By adopting the above technical solution, the serpentine shape of the connecting cavity can prolong the time for residual heat air to circulate, thereby enabling the heat-conducting seat to absorb more heat.

[0018] Furthermore, a motor is installed on one side of the outer surface of the base, and the output end of the motor is connected to a conveyor roller track. The conveyor roller track includes multiple conveyor rollers, multiple synchronous pulleys connected to both ends of the multiple conveyor rollers, and multiple synchronous belts connected between the multiple synchronous pulleys.

[0019] By adopting the above technical solution, the motor output drives the conveyor roller to operate, thereby sending the lower mold on the right side of the outer shell into the preheating chamber, sending the lower mold in the preheating chamber into the heating chamber, sending the lower mold in the heating chamber into the cooling chamber, and conveying the lower mold in the cooling chamber to the left side of the outer shell.

[0020] Furthermore, a lower mold is provided on the top of the conveyor roller, and a tempered glass blank is placed on the top of the lower mold. A second cylinder is installed above the cooling chamber, and the output end of the second cylinder is connected to the upper mold. A heater is installed below the heating chamber.

[0021] By adopting the above technical solution, the heater generates heat to raise the temperature in the heating chamber, thereby heating and softening the tempered glass blank in the heating chamber; the second cylinder drives the upper mold to move down, which, together with the lower mold in the cooling chamber, bends the tempered glass blank in the cooling chamber into shape.

[0022] Furthermore, a cooling fan is installed on one side of the outer surface of the housing, and the air outlet of the cooling fan is connected to a cooling spray pipe, and multiple cooling spray pipes are provided.

[0023] By adopting the above technical solution, airflow is generated by a cooling fan and blown evenly onto the surface of the tempered glass blank through multiple cooling nozzles, so that the tempered glass blank is cooled quickly, thereby increasing the strength of the tempered glass blank.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the arrangement of a preheating chamber, a preheating fan, a heat-conducting base, and heat dissipation fins, allows the waste heat air generated from cooling the tempered glass blank in the cooling chamber to be sent to the heat-conducting base through an insulated diversion pipe after the preheating fan starts. The waste heat air then enters the insulated confluence pipe through the connecting cavity and is discharged by the preheating fan. While the waste heat air circulates in the connecting cavity, the heat of the waste heat air is transferred to the heat dissipation fins through the heat-conducting base. The heat is then dissipated into the preheating chamber through the heat dissipation fins, raising the temperature of the preheating chamber to facilitate the preheating of the subsequent tempered glass blank and reducing heater energy consumption. Preheating through waste heat recovery reduces heat resource waste and lowers heater energy consumption.

[0026] 2. By designing a connecting cavity, the serpentine shape of which extends the time for residual heat air to circulate, the heat-conducting seat can absorb more heat, thereby improving the utilization rate of heat resources and further reducing heat resource waste.

[0027] 3. This utility model reduces the exchange of residual heat air with the outside temperature by setting up an insulated confluence pipe, an insulated sleeve, and an insulated diversion pipe. This allows most of the heat to be dissipated into the preheating chamber through the heat-conducting base and heat dissipation fins, thereby improving the utilization rate of heat resources and further reducing the waste of heat resources.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] A high-strength tempered glass bending and forming equipment, such as Figures 1-4 As shown, the device includes a base 1 and a housing 6. Inside the housing 6, from left to right, are a cooling chamber 15, a heating chamber 14, and a preheating chamber 13. A preheating fan 17 is installed on one side of the top of the housing 6. The air inlet of the preheating fan 17 is connected to a heat insulation sleeve 19 via a heat insulation confluence pipe 18. A heat-conducting seat 21, made of copper, is fixed inside the heat insulation sleeve 19. A connecting cavity 22 is formed inside the heat-conducting seat 21. Two heat insulation sleeves 19, heat-conducting seats 21, and connecting cavities 22 are provided, arranged in a mirror image. Heat dissipation fins 23, made of aluminum alloy, are fixed to the outer surface of the heat-conducting seat 21. Multiple heat dissipation fins 23 are equidistantly distributed and divided into two groups, symmetrically distributed. One side of the heat insulation sleeve 19 is connected to... The preheating fan 17, connected to the heat-insulating diversion pipe 20, sends the waste heat air generated from cooling the tempered glass blank 5 in the cooling chamber 15 into the heat-conducting seat 21 through the heat-insulating diversion pipe 20. The waste heat air enters the heat-insulating confluence pipe 18 through the connecting cavity 22 and then enters the preheating fan 17 to be discharged. At the same time, the heat-insulating confluence pipe 18, the heat-insulating sleeve 19 and the heat-insulating diversion pipe 20 reduce the exchange of temperature between the waste heat air and the outside environment, so that most of the heat can be dissipated into the preheating chamber 13 through the heat-conducting seat 21 and the heat dissipation fins 23, thereby improving the utilization rate of heat resources. While the waste heat air circulates in the connecting cavity 22, the heat of the waste heat air is transferred to the heat dissipation fins 23 through the heat-conducting seat 21, and then the heat is dissipated into the preheating chamber 13 through the heat dissipation fins 23, so that the preheating chamber 13 is heated to facilitate the preheating of the tempered glass blank 5 and reduce the energy consumption of the heater 16.

[0037] See Figure 1 and Figure 2 In the above embodiment, the cooling chamber 15, heating chamber 14, and preheating chamber 13 are interconnected. A first cylinder 7 is installed inside the upper part of the outer shell 6, and the output end of the first cylinder 7 is connected to a sealing door 8. A motor 2 is installed on one side of the outer surface of the base 1, and the output end of the motor 2 is connected to a conveyor roller conveyor 3. The conveyor roller conveyor 3 includes multiple conveyor rollers, multiple synchronous pulleys connected to the two ends of the multiple conveyor rollers, and multiple synchronous belts connected between the multiple synchronous pulleys. A lower mold 4 is provided on the top of the conveyor roller conveyor 3, allowing material to be fed from the right side of the outer shell 6 and discharged from the left side of the outer shell 6. The preheating chamber 13, heating chamber 14, and cooling chamber 15 all contain the lower mold 4 and the tempered glass blank 5. After heating and cooling are completed, the first cylinder 7 drives the sealing door 8 to move upward. At this time, the output end of the motor 2 drives the conveyor roller 3 to operate, thereby sending the lower mold 4 on the right side of the outer shell 6 into the preheating chamber 13, sending the lower mold 4 in the preheating chamber 13 into the heating chamber 14, sending the lower mold 4 in the heating chamber 14 into the cooling chamber 15, and conveying the lower mold 4 in the cooling chamber 15 to the left side of the outer shell 6. Then, the operator removes the tempered glass blank 5 from the lower mold 4 on the left side of the outer shell 6. The lower mold 4 is pushed from the outside to the right side of the outer shell 6. Then, the worker places the tempered glass blank 5, which is to be bent into shape, on top of the lower mold 4 on the right side of the outer shell 6. This process is repeated. The tempered glass blank 5 is placed on top of the lower mold 4. A second cylinder 9 is installed above the interior of the cooling chamber 15. The output end of the second cylinder 9 is connected to the upper mold 10. A cooling fan 11 is installed on one side of the outer surface of the outer shell 6. The outlet end of the cooling fan 11 is connected to a cooling spray pipe 12. Multiple cooling spray pipes 12 are provided. A heater 16 is installed below the interior of the heating chamber 14. This equipment operates... During the process, the heater 16 generates heat to raise the temperature inside the heating chamber 14, thereby heating and softening the tempered glass blank 5 inside the heating chamber 14. The second cylinder 9 drives the upper mold 10 to move down, which, together with the lower mold 4 in the cooling chamber 15, bends the tempered glass blank 5 in the cooling chamber 15 into shape. Then, the second cylinder 9 drives the upper mold 10 up, and during this process, the cooling fan 11 generates airflow, which is then blown evenly onto the surface of the tempered glass blank 5 through multiple cooling nozzles 12, so that the tempered glass blank 5 is cooled quickly, thereby increasing the strength of the tempered glass blank 5.

[0038] Example 2:

[0039] Based on the above embodiment one, the following settings are now adopted to increase heat utilization.

[0040] See Figure 4 In the above embodiment, the connecting cavity 22 is serpentine, which can prolong the time for residual heat air to circulate, thereby enabling the heat-conducting seat 21 to absorb more heat.

[0041] The implementation principle of this utility model is as follows: First, this equipment completes production in an assembly line manner. Material is fed from the right side of the outer shell 6 and discharged from the left side of the outer shell 6. The lower mold 4 and tempered glass blank 5 are present in the preheating chamber 13, heating chamber 14 and cooling chamber 15. After heating and cooling are completed, the first cylinder 7 drives the sealing door 8 to move upward. At this time, the output end of the motor 2 drives the conveyor roller 3 to operate, thereby sending the lower mold 4 on the right side of the outer shell 6 into the preheating chamber 13, sending the lower mold 4 in the preheating chamber 13 into the heating chamber 14, sending the lower mold 4 in the heating chamber 14 into the cooling chamber 15, and conveying the lower mold 4 in the cooling chamber 15 to the left side of the outer shell 6. Then, the operator removes the tempered glass blank 5 from the lower mold 4 on the left side of the outer shell 6 and pushes the lower mold 4 from the outside to the right side of the outer shell 6. Then, the operator places the tempered glass blank 5, which is ready to be bent into shape, on the top of the lower mold 4 on the right side of the outer shell 6, and so on.

[0042] During operation, the heater 16 generates heat to raise the temperature inside the heating chamber 14, thereby heating and softening the tempered glass blank 5 inside the heating chamber 14. The second cylinder 9 drives the upper mold 10 to move downward, which, together with the lower mold 4 in the cooling chamber 15, bends the tempered glass blank 5 in the cooling chamber 15 into shape. Then, the second cylinder 9 drives the upper mold 10 to move upward, and during this process, the cooling fan 11 generates airflow, which is then blown evenly onto the surface of the tempered glass blank 5 through multiple cooling nozzles 12, so that the tempered glass blank 5 is cooled quickly, thereby increasing the strength of the tempered glass blank 5.

[0043] After the preheating fan 17 starts, the waste heat air generated from cooling the tempered glass blank 5 in the cooling chamber 15 is sent to the heat-conducting seat 21 through the heat-insulating diversion pipe 20. The waste heat air enters the heat-insulating confluence pipe 18 through the connecting cavity 22 and then enters the preheating fan 17 to be discharged. At the same time, the heat-insulating confluence pipe 18, heat-insulating sleeve 19 and heat-insulating diversion pipe 20 reduce the exchange of temperature between the waste heat air and the outside environment, so that most of the heat can be dissipated into the preheating chamber 13 through the heat-conducting seat 21 and the heat dissipation fins 23, thereby improving the utilization rate of heat resources. While the waste heat air flows in the connecting cavity 22, the heat of the waste heat air is transferred to the heat dissipation fins 23 through the heat-conducting seat 21. The serpentine shape of the connecting cavity 22 can prolong the flow time of the waste heat air, so that the heat-conducting seat 21 can absorb more heat. Then, the heat is dissipated into the preheating chamber 13 through the heat dissipation fins 23, so that the preheating chamber 13 is heated to facilitate the preheating of the tempered glass blank 5 and reduce the energy consumption of the heater 16.
