Depending on the technical requirements of various aircraft, it must possess multiple functions. First, as a structural component, it must have sufficient strength to withstand cabin pressure, aerodynamic loads, and airframe structural loads. Second, as a transparent observation window, it must possess excellent optical performance. Third, it must have reliable operation and a long service life; the glass forming process requires specialized forming equipment.

[0003] Chinese patent CN120081585A discloses a glass tempering and bending forming apparatus, including a main body. A high-temperature chamber is located on the left side inside the main body. A forming component is located inside the main body and is hydraulically driven. A forming auxiliary component is located at the top inside the main body, with an arc-shaped bottom. Transmission components are located on both the left and right sides inside the main body, and these transmission components operate via a drive module. A preparatory frame is fixedly installed on the left side of the main body, and a fixing plate is fixedly installed on the left side of the preparatory frame. A dual-head motor is fixedly installed on the side of the fixing plate away from the center of the preparatory frame, and an arc-groove rod is fixedly installed at the output end of the dual-head motor near the center of the preparatory frame. In the aforementioned application, during the high-temperature glass block forming process, due to the high internal temperature of the glass block, a long cooling time is required after forming to solidify the glass, reducing the equipment's efficiency.

A sliding plate is fixedly connected to the left side of the upper mold moving device. A fixing plate is fixedly connected inside the outer shell. A sliding groove is opened inside the fixing plate, and a sliding plate is movably connected inside the sliding groove. A hydraulic block is fixedly connected to the bottom of the sliding groove. A push block is movably connected to the top of the hydraulic block. A spring is fixedly connected between the push block and the hydraulic block.

The bottom of the fixing plate is fixedly connected to one end of a hose, and the other end of the hose is fixedly connected to the bottom of the hydraulic block. The hydraulic block is movably connected to an air outlet block via a transmission component. The air outlet block allows the upper mold moving device to move downwards. After the high-temperature glass block is formed, it needs to be cooled. At this time, the air outlet block moves upwards, unblocking the air outlet and allowing low-temperature nitrogen gas to be sprayed from the air outlet onto the high-temperature glass block, thereby rapidly cooling and solidifying the formed glass and improving the equipment's production efficiency.

[0006] Preferably, the transmission component includes a fixed plate three, a push block two, a fixed frame, a vent pipe, and a compressed liquid nitrogen tank. The fixed frame is fixedly connected to both sides of the inner side of the outer shell. The hydraulic block two is fixedly connected to the inside of the fixed frame. The fixed plate three is fixedly connected to the bottom of the hydraulic block two. The push block two is movably connected to the top of the hydraulic block two.

[0007] Preferably, an oil suction device is movably connected inside the outer shell, a baffle is fixedly connected inside the outer shell, an auxiliary unloading assembly is movably connected inside the lower mold, and an anti-oxidation spot assembly is movably connected inside the outer shell.

[0008] Preferably, the inner surface of the air outlet block is provided with an air outlet hole, and the scraper device is internally connected with a telescopic device.

[0009] Preferably, the auxiliary unloading assembly includes a push block three, a spring two, a hydraulic block three, a hose two, a groove, a hydraulic block four, a push block four, a rotating block, a rotating shaft, a movable plate, and an anti-slip groove. The top inner side of the outer shell is fixedly connected to the hydraulic block three, the bottom of the hydraulic block three is movably connected to the push block three, the spring two is fixedly connected between the push block three and the hydraulic block three, the top of the hydraulic block three is fixedly connected to one end of the hose two, the other end of the hose two is fixedly connected to the top of the hydraulic block four, the outer side of the hydraulic block four is fixedly connected to the interior of the lower mold, the bottom of the hydraulic block four is movably connected to the push block four, and the rear side of the push block four is fixedly connected to the rotating block four. The surface of the lower mold has a groove, the interior of the groove is movably connected to the rotating shaft, the left side of the rotating shaft is fixedly connected to the rotating block, the outer side of the rotating shaft is fixedly connected to the movable plate, and the surface of the movable plate has an anti-slip groove. An auxiliary unloading component is installed. After the high-temperature glass block completes the forming process, the tension of the solidified glass surface makes it easy for the bottom of the glass to form a suction force with the lower mold, which prevents the rear transport equipment from completing the unloading process. At this time, the upper mold moving device moves upward, causing the rotating shaft to rotate and the movable plate to rotate upward. The formed glass block is then moved by the movable plate to the surface of the rear transport equipment, allowing the unloading process to proceed smoothly, reducing the number of manual maintenance steps, and improving the working efficiency of the equipment.

[0010] Preferably, the surface of the movable plate coincides with the top surface of the lower mold, and the surface of the movable plate is fixedly connected with a temperature-resistant and anti-slip coating.

[0011] Preferably, the size of the movable plate is the same as the size of the groove, and the length of the anti-slip groove is less than the length of the movable plate.

[0012] Preferably, the anti-oxidation spot assembly includes a hose three, a fixing plate four, a hydraulic block five, a push block five, a valve, an air outlet pipe, an air pump, a nitrogen chamber, a fixing block, and a nozzle. The top of the hydraulic block three is fixedly connected to one end of the hose three, and the other end of the hose three is fixedly connected to the top of the hydraulic block five. The outer side of the hydraulic block five is fixedly connected to the inside of the outer shell. The bottom of the hydraulic block five is movably connected to the push block five, and the right side of the push block five is movably connected to the valve. The top of the outer shell is fixedly connected to the air pump, and the bottom of the air pump is fixedly connected to the air outlet pipe. The inside of the air outlet pipe is movably connected to the valve. The bottom of the air outlet pipe is fixedly connected to the fixing block, and the bottom surface of the fixing block is fixedly connected to the nozzle. The top of the outer shell is fixedly connected to the nitrogen chamber. An anti-oxidation spot component is installed. When the high-temperature glass block moves out of the heating and insulation chamber, it is easy to react with oxygen in the air to form oxidation spots and oxidation fog layers, which reduces the glass yield. At this time, the upper mold moving device resets, causing the valve to open automatically, so that nitrogen in the nitrogen chamber is blown out from the nozzle to the surface of the high-temperature glass block, thereby reducing the contact area between the high-temperature glass block and oxygen, thus reducing the formation of oxidation spots and improving the equipment yield.

[0013] Preferably, the bottom of the fixing block has an angled opening, and the central axis of the nozzle is not perpendicular to the surface of the front transport equipment.

[0014] A forming method for an aerospace glass forming apparatus includes: Step 1: Before starting the transport equipment, move the high-temperature glass block in the heating and insulation chamber into the outer shell. At this time, start the scraper equipment to make the two sides of the high-temperature glass block bend first, and at the same time, the oil suction equipment absorbs the oil volatiles on the surface of the high-temperature glass block. Step 2: When the high-temperature glass block moves to the surface of the lower mold, start the electric hydraulic cylinder to move the upper mold moving device downward to press the high-temperature glass block into a curved shape. At this time, the slide moves downward, causing the air vents on both sides to move upward, separating the air vents from the fixed frame, and allowing the low-temperature nitrogen gas in the compressed liquid nitrogen chamber to be sprayed out from the air vents, so that the high-temperature glass block can be cooled down and formed quickly. Step 3: After the glass block is formed, the upper mold moving device moves upward, causing the movable plate to rotate with the rotating shaft, and the movable plate pushes the formed glass block to the rear transport equipment; Step 4: Start the air pump to automatically open the valve, allowing nitrogen gas in the nitrogen chamber to be sprayed from the nozzle onto the surface of the next piece of high-temperature glass, thus preventing oxidation spots. At the same time, start the rear transport equipment to carry the formed glass block out of the casing.

[0015] The advantages of this application are: (1) In this application, the upper mold moving equipment moves downward. After the high temperature glass block is formed, it needs to be cooled down. At this time, the air block moves upward, so that the air hole is unblocked and low temperature nitrogen is sprayed from the air hole to the high temperature glass block, thereby rapidly cooling and solidifying the formed glass, thus improving the production efficiency of the equipment.

[0016] (2) After the high-temperature glass block completes the forming process, the tension of the glass solidification surface makes it easy for the bottom of the glass to form a suction force with the lower mold, which makes it impossible for the rear transport equipment to complete the unloading process. At this time, the upper mold mobile device moves upward, causing the rotating shaft to rotate and the movable plate to rotate upward, so that the formed glass block is moved to the surface of the rear transport equipment by the movable plate, so that the unloading process of the equipment can proceed smoothly, reducing the steps of manual maintenance of the equipment and improving the working efficiency of the equipment.

[0017] (3) When the high-temperature glass block is moved out of the heating and insulation chamber, it is easy to react with oxygen in the air to form oxide spots and oxide fog layer, which reduces the glass yield. At this time, the upper mold device is reset, the valve is automatically opened, and the nitrogen in the nitrogen chamber is blown out from the nozzle to the surface of the high-temperature glass block, thereby reducing the contact area between the high-temperature glass block and oxygen, thereby reducing the formation of oxide spots and improving the equipment yield.

Detailed Implementation

[0021] Example 1, as Figures 1-4 As shown, an aerospace glass forming apparatus and forming method include: The outer casing 100 has a front transport device 200 on its inner front side and a rear transport device 300 on its inner rear side. The outer casing 100 also has a scraper device 400 with a shaping function inside. The inner bottom of the outer casing 100 has a lower mold 700, which is used to shape the high-temperature glass block according to the shape of the lower mold 700. The inner top of the outer casing 100 has an upper mold moving device 800. A sliding plate 901 is fixedly connected to the left side of the upper mold moving device 800. A fixing plate 902 is fixedly connected inside the outer shell 100. A sliding groove 903 is provided inside the fixing plate 902 to allow the sliding plate 901 to move along the groove 903. The sliding plate 901 is movably connected inside the sliding groove 903. A hydraulic block 906 is fixedly connected to the bottom of the sliding groove 903. A push block 904 is movably connected to the top of the hydraulic block 906. The push block 904 and the hydraulic block 906 are connected to each other. A spring 905 is fixedly connected between 06. The spring 905 is set so that the push block 904 can automatically reset. A fixing plate 907 is fixedly connected to the bottom of the hydraulic block 906. The bottom of the fixing plate 907 is fixedly connected to one end of the hose 908. The other end of the hose 908 is fixedly connected to the bottom of the hydraulic block 910. The hose 908 is set so that the inside of the hydraulic block 906 communicates with the inside of the hydraulic block 910. The hydraulic block 910 is movably connected to the air outlet block 912 through a transmission component.

[0022] The transmission components include a fixed plate 3 909, a push block 2 911, a fixed frame 913, a vent pipe 914, and a compressed liquid nitrogen tank 915. The fixed frame 913 is fixedly connected to both sides of the interior of the outer shell 100. The hydraulic block 2 910 is fixedly connected to the interior of the fixed frame 913. The fixed plate 3 909 is fixedly connected to the bottom of the hydraulic block 2 910. The push block 2 911 is movably connected to the top of the hydraulic block 2 910. The air outlet block 912 is movably connected to the top of the push block 2 911. The outer side of the air outlet block 912 is movably connected to the interior of the fixed frame 913. The outer side of the air outlet block 912 is fixedly connected to the vent pipe 914. The compressed liquid nitrogen tank 915 is fixedly connected to the bottom of the inner side of the outer shell 100.

[0023] An oil suction device 500 is movably connected inside the outer casing 100 to remove the oil mixture on the surface of the high-temperature glass block. A baffle 600 is fixedly connected inside the outer casing 100 to prevent dust particles from splashing onto the surface of the high-temperature glass block. An auxiliary unloading assembly 1000 is movably connected inside the lower mold 700. An anti-oxidation spot assembly 1100 is movably connected inside the outer casing 100.

[0024] The inner surface of the air outlet block 912 is provided with an air outlet hole, and the scraper device 400 is internally connected with a telescopic device.

[0025] The vent block 912 is set up so that the upper mold moving device 800 moves downward. After the high-temperature glass block is formed, it needs to be cooled down. At this time, the vent block 912 moves upward so that the vent hole is unblocked and low-temperature nitrogen gas is sprayed from the vent hole onto the high-temperature glass block, thereby rapidly cooling and solidifying the formed glass and improving the production efficiency of the equipment.

[0026] A method for forming aerospace glass, comprising: Step 1: Start the pre-transport equipment 200 to move the high-temperature glass block in the heating and insulation chamber into the outer shell 100. At this time, start the scraper equipment 400 to make the two sides of the high-temperature glass block bend first, and at the same time, the oil suction equipment 500 absorbs the oil volatiles on the surface of the high-temperature glass block. Step 2: When the high-temperature glass block moves to the surface of the lower mold 700, the electric hydraulic cylinder is activated to move the upper mold moving device 800 downward to press the high-temperature glass block into a curved shape. At this time, the slide plate 901 moves downward, causing the air vent blocks 912 on both sides to move upward, so that the air vents are separated from the fixed frame 913, and the low-temperature nitrogen gas in the compressed liquid nitrogen chamber 915 is sprayed out from the air vent blocks 912, so that the high-temperature glass block cools down and is formed quickly. Step 3: After the glass block is formed, the upper mold moving device 800 is reset, so that the movable plate 1010 rotates with the rotating shaft 1009, and the movable plate 1010 pushes the formed glass block to the rear transport device 300. Step 4: Start the air pump 1107 to automatically open the valve 1105, so that the nitrogen in the nitrogen chamber 1108 can be sprayed from the nozzle 1110 onto the surface of the next high-temperature glass block, thereby preventing oxidation spots. At the same time, start the rear transport equipment 300 so that the formed glass block can be carried out of the outer casing 100 by the rear transport equipment 300.

[0027] In practical use, when the above equipment starts working, the pre-transport equipment 200 is started to move the high-temperature glass block into the outer shell 100. The scraper equipment 400 is started to stabilize the surface of the high-temperature glass block. When the high-temperature glass block moves to the top of the lower mold 700, the upper mold moving equipment 800 is started to move downward, causing the slide plate 901 to move downward along the slide groove 903. This causes the push block 904 to move downward, increasing the internal pressure of the hydraulic block 906. The internal pressure of the hydraulic block 906 is then transmitted to the hydraulic block 910 through the hose 908, increasing the internal pressure of the hydraulic block 910. This causes the push block 911 to move upward, causing the vent block 912 to slide upward out of the fixed frame 913. This allows the low-temperature nitrogen gas inside the compressed liquid nitrogen chamber 915 to be sprayed onto the high-temperature glass block from the vent, thereby rapidly cooling and solidifying the formed glass and improving the production efficiency of the equipment.

[0028] Example 2, as Figures 1-6As shown, an aviation glass forming apparatus and forming method, based on Embodiment 1, includes an auxiliary unloading assembly 1000 comprising a pusher block 3 1001, a spring 2 1002, a hydraulic block 3 1003, a hose 2 1004, a groove 1005, a hydraulic block 4 1006, a pusher block 4 1007, a rotating block 1008, a rotating shaft 1009, a movable plate 1010, and an anti-slip groove 1011. The hydraulic block 3 1003 is fixedly connected to the top inner side of the outer shell 100, and the pusher block 3 1001 is movably connected to the bottom of the hydraulic block 3 1003. A spring 2 1002 is fixedly connected between the pusher block 3 1001 and the hydraulic block 3 1003. The spring 2 1002 is configured to automatically reset the pusher block 3 1001. The top of the hydraulic block 3 1003 is connected to one end of the hose 2 1004. The other end of the second hose 1004 is fixedly connected to the top of the fourth hydraulic block 1006. The second hose 1004 is provided so that the interior of the third hydraulic block 1003 communicates with the interior of the fourth hydraulic block 1006. The outer side of the fourth hydraulic block 1006 is fixedly connected to the interior of the lower mold 700. The bottom of the fourth hydraulic block 1006 is movably connected to the fourth push block 1007. The rear side of the fourth push block 1007 is fixedly connected to the rotating block 1008. The surface of the lower mold 700 is provided with a groove 1005. The interior of the groove 1005 is movably connected to the rotating shaft 1009. The left side of the rotating shaft 1009 is fixedly connected to the rotating block 1008. The outer side of the rotating shaft 1009 is fixedly connected to the movable plate 1010. The surface of the movable plate 1010 is provided with an anti-slip groove 1011.

[0029] The surface of the movable plate 1010 coincides with the top surface of the lower mold 700, and the surface of the movable plate 1010 is fixedly connected with a heat-resistant and anti-slip coating.

[0030] The size of the movable plate 1010 is the same as the size of the groove 1005, and the length of the anti-slip groove 1011 is less than the length of the movable plate 1010.

[0031] An auxiliary unloading component 1000 is installed. After the high-temperature glass block completes the forming process, the tension of the solidified glass surface makes it easy for the bottom of the glass to form a suction force with the lower mold 700, which prevents the rear transport equipment 300 from completing the unloading process. At this time, the upper mold moving device 800 moves upward, causing the rotating shaft 1009 to rotate, which in turn causes the movable plate 1010 to rotate upward. This allows the formed glass block to be moved by the movable plate 1010 to the surface of the rear transport equipment 300, making the unloading process of the equipment proceed smoothly, reducing the number of manual maintenance steps, and improving the working efficiency of the equipment.

[0032] In practical use, after the high-temperature glass block completes the forming process, the tension of the solidified glass surface makes it easy for the bottom of the glass to form a suction force with the lower mold 700, thus preventing the rear transport equipment 300 from completing the unloading process. This causes the upper mold moving equipment 800 to reset, causing the push block 1001 to move upward, increasing the internal pressure of the hydraulic block 1003. The internal pressure of the hydraulic block 1003 is then transmitted to the hydraulic block 1006 through the hose 1004, causing the push block 1007 to push outward, causing the rotating block 1008 to rotate, causing the rotating shaft 1009 to rotate, and causing the movable plate 1010 to rotate with the rotating shaft 1009. This allows the formed glass block to be moved to the surface of the rear transport equipment 300 by the movable plate 1010, ensuring a smooth unloading process, reducing manual maintenance steps, and improving equipment efficiency.

[0033] Example 3, as Figures 1-8 As shown, an aviation glass forming apparatus and forming method, based on Embodiments 1 and 2, includes an anti-oxidation spot component 1100 comprising a hose 1101, a fixing plate 1102, a hydraulic block 1103, a pusher 1104, a valve 1105, an air outlet pipe 1106, an air pump 1107, a nitrogen chamber 1108, a fixing block 1109, and a nozzle 1110. The top of the hydraulic block 1003 is fixedly connected to one end of the hose 1101, and the other end of the hose 1101 is fixedly connected to the top of the hydraulic block 1103. The hose 1101 is configured to allow communication between the interior of the hydraulic block 1003 and the interior of the hydraulic block 1103. The outer side of the hydraulic block 1103 is fixedly connected to the inside of the outer shell 100. The bottom of the hydraulic block 1103 is movably connected to the push block 1104. The right side of the push block 1104 is movably connected to the valve 1105. The top of the outer shell 100 is fixedly connected to the air pump 1107. The bottom of the air pump 1107 is fixedly connected to the air outlet pipe 1106. The inside of the air outlet pipe 1106 is movably connected to the valve 1105. The bottom of the air outlet pipe 1106 is fixedly connected to the fixing block 1109. The bottom surface of the fixing block 1109 is fixedly connected to the nozzle 1110. The top of the outer shell 100 is fixedly connected to the nitrogen chamber 1108.

[0034] The bottom of the fixing block 1109 is provided with an oblique opening. The oblique opening increases the air outlet area of ​​the nozzle 1110. The central axis of the nozzle 1110 is not perpendicular to the surface of the front transport device 200.

[0035] The anti-oxidation spot component 1100 is installed so that when the high-temperature glass block moves out of the heating and insulation chamber, it is easy to react with oxygen in the air to form oxidation spots and oxidation fog layer, which reduces the glass yield. At this time, the upper mold moving device 800 is reset, which automatically opens the valve 1105, allowing nitrogen in the nitrogen chamber 1108 to be blown out from the nozzle 1110 onto the surface of the high-temperature glass block, thereby reducing the contact area between the high-temperature glass block and oxygen, thus reducing the formation of oxidation spots and improving the equipment yield.

[0036] When the above equipment is used, when the internal pressure of hydraulic block 3 1003 increases, the excess pressure inside hydraulic block 3 1003 is transmitted to hydraulic block 5 1103 through hose 3 1101, increasing the internal pressure of hydraulic block 5 1103. This causes push block 5 1104 to be pushed outward, which opens valve 1105, allowing nitrogen gas inside nitrogen chamber 1108 to be sprayed from nozzle 1110 onto the high-temperature glass block. This reduces the contact area between the high-temperature glass block and oxygen, thereby reducing the formation of oxide spots and improving the equipment yield.

10. A forming method for an aviation glass forming apparatus according to claims 1-9, characterized in that, include: Step 1: Before starting the transport equipment, move the high-temperature glass block in the heating and insulation chamber into the outer shell. At this time, start the scraper equipment to make the two sides of the high-temperature glass block bend first, and at the same time, the oil suction equipment absorbs the oil volatiles on the surface of the high-temperature glass block. Step 2: When the high-temperature glass block moves to the surface of the lower mold, start the electric hydraulic cylinder to move the upper mold moving device downward to press the high-temperature glass block into a curved shape. At this time, the slide moves downward, causing the air vents on both sides to move upward, separating the air vents from the fixed frame, and allowing the low-temperature nitrogen gas in the compressed liquid nitrogen chamber to be sprayed out from the air vents, so that the high-temperature glass block can be cooled down and formed quickly. Step 3: After the glass block is formed, the upper mold moving equipment is reset, so that the movable plate follows the rotating shaft and pushes the formed glass block to the rear transport equipment. Step 4: Start the air pump to automatically open the valve, allowing nitrogen gas in the nitrogen chamber to be sprayed from the nozzle onto the surface of the next piece of high-temperature glass, thus preventing oxidation spots. At the same time, start the rear transport equipment to carry the formed glass block out of the casing.
