Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a hot bending forming equipment for explosion-proof glass. Background Technology

[0002] As glass becomes increasingly used in various aspects of life, the demand for explosion-proof glass is growing. In our daily lives, we often see explosion-proof glass in curved or spherical shapes. These curved shapes need to be produced by hot bending, which requires hot bending forming equipment.

[0003] Existing hot bending equipment softens glass by heating it and then applies external force to its surface to achieve bending. The hot bending process mainly involves the following steps: heating, bending, and cooling. First, the glass plate is placed on the hot bending machine's worktable. Then, the glass is heated using heating wires or flames to raise its temperature to its softening temperature. The heating temperature and time need to be determined based on the type of glass and the bending angle. After the glass softens, bending is required; however, the temperature of the mold is difficult to match the glass's heating temperature. When the mold contacts the glass surface, it lowers the surface temperature, causing the glass surface to become brittle rapidly.

[0004] The aforementioned hot bending forming equipment has a large temperature difference between the mold and the glass surface, which makes it easy for the glass surface temperature to drop during the molding process, causing damage and increasing the defect rate of the hot bending forming equipment. Utility Model Content

[0005] This invention proposes a hot bending forming equipment for explosion-proof glass to solve the problem in the prior art where a large temperature difference between the mold and the glass easily causes the glass to crack.

[0006] The technical solution of this utility model is as follows: A hot bending forming equipment for explosion-proof glass, comprising a support plate and a fixing plate, and further comprising:

[0007] The connecting frame is installed on the upper surface of the support plate. An auxiliary block is installed inside the connecting frame. A support rod is installed on the upper surface of the connecting frame. A lower pressure plate is slidably connected to the outer surface of the support rod. A lower pressure block is installed on the lower surface of the lower pressure plate. The first heat-conducting plate is installed inside the lower pressure block. A second heat-conducting plate is installed on the outer side of the first heat-conducting plate. The ventilation pipe passes through the interior of the support plate. A heating wire is installed inside the ventilation pipe. An auxiliary fan passes through the ventilation pipe. The connecting piece is installed on the front side of the fixed plate. A threaded rod is rotatably connected inside the connecting piece. A threaded tube is threadedly connected to the outer surface of the threaded rod. A movable plate is installed on the outer surface of the threaded tube. The front side of the movable plate is installed on the back side of the lower pressure plate. A drive motor is installed on the upper surface of the fixed plate. The output end of the drive motor is keyed to the top of the threaded rod.

[0008] In a preferred embodiment of the explosion-proof glass hot bending forming equipment of this utility model, in order to facilitate the operator to adjust and move the position of the block, the support plate is slidably connected to the inside of the moving block, the upper surface of the moving block is mounted with an mounting plate, and the upper surface of the moving block is threaded with a fixing pin.

[0009] In a preferred embodiment of the explosion-proof glass hot bending forming equipment of this utility model, in order to better fix the adjusted moving block, one end of the fixing pin inserted into the moving block abuts against the support plate, and a fixing plate is installed on the upper surface of the mounting plate.

[0010] As a preferred embodiment of the explosion-proof glass hot bending forming equipment of this utility model, in order to facilitate the second heat-conducting plate to absorb heat on the outer surface of the ventilation pipe, a support plate is installed on the back of the fixing plate, and a connecting hole is opened inside the second heat-conducting plate, the size of the connecting hole being adapted to the size of the ventilation pipe.

[0011] In a preferred embodiment of the explosion-proof glass hot bending forming equipment of this utility model, in order to better block the glass, a connecting hook is provided on the outer surface of the support rod located on the front side, an auxiliary rod is installed on the inner side of the connecting hook, and a buffer spring is installed on the inner side of the auxiliary rod.

[0012] In a preferred embodiment of the explosion-proof glass hot bending forming equipment of this utility model, in order to prevent the glass from shifting as the support plate moves, a fixed frame is installed at the inner end of the buffer spring, and the auxiliary rod is slidably connected in the fixed frame.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, the first heat-conducting plate moves downward, causing the second heat-conducting plate to move downward and fit onto the outer surface of the ventilation pipe, thus conducting heat. Compared to the prior art of directly processing glass, this device can heat the lower pressure block, preventing the glass surface from cooling down due to direct hot bending of the lower pressure block.

[0015] In this invention, by activating an auxiliary fan, air is blown into the ventilation duct, causing the air to carry heat and heat the top of the ventilation duct. Compared to the existing technology where there is a large temperature difference between the mold and the glass, this device can reduce the temperature difference between the lower pressing block and the glass, avoiding damage to the glass surface caused by a large temperature difference during the molding process, and reducing the defect rate of the glass processed by this device.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-5 As shown, this embodiment proposes an explosion-proof glass hot bending forming equipment, including a support plate 1 and a fixed plate 17, as well as a connecting frame 2, an auxiliary block 3, a support rod 4, a lower pressure plate 5, a lower pressure block 6, a first heat-conducting plate 7, a second heat-conducting plate 8, a ventilation pipe 9, a heating wire 10, an auxiliary fan 11, a connecting piece 12, a threaded rod 13, a threaded pipe 14, a moving plate 15, and a drive motor 16;

[0025] like Figure 4 and Figure 5 As shown, the connecting frame 2 is installed on the upper surface of the support plate 1. An auxiliary block 3 is installed inside the connecting frame 2. A support rod 4 is installed on the upper surface of the connecting frame 2. A lower pressure plate 5 is slidably connected to the outer surface of the support rod 4. A lower pressure block 6 is installed on the lower surface of the lower pressure plate 5. It should be noted that the lower pressure block 6 has a cavity inside, and the opening of the cavity is located on the back of the lower pressure block 6. Therefore, the first heat-conducting plate 7 can be installed inside the lower pressure block 6. There are five sets of first heat-conducting plates 7, which can transfer the heat carried by the second heat-conducting plate 8 to the lower pressure block 6 at multiple points, so that the lower pressure block 6 can be preheated quickly. The second heat-conducting plate 8 is installed on the outer side of the first heat-conducting plate 7. A connecting hole is opened inside the second heat-conducting plate 8. The size of the connecting hole is adapted to the size of the ventilation pipe 9. When the second heat-conducting plate 8 moves downward, the ventilation pipe 9 is inserted into the second heat-conducting plate 8 through the connecting hole, and the heat of the ventilation pipe 9 is carried away to heat the lower pressure block 6. The duct 9 runs through the interior of the support plate 1. A heating wire 10 is installed inside the duct 9, and an auxiliary fan 11 is installed inside the duct 9. When the heating wire 10 is energized, it heats up. When the auxiliary fan 11 is started, its output end rotates and blows air into the duct 9, so that the air carries away the heat generated by the heating wire 10. Most of the heat is retained at the top of the duct 9. It should be noted that the heating wire 10 is a common resistance heating wire on the market. The duct 9 is a straight tube, so there will be no misalignment when the second heat-conducting plate 8 moves downward. The connecting piece 12 is installed on the front of the fixed plate 17. The connecting piece 12 is rotatably connected to a threaded rod 13. The outer surface of the threaded rod 13 is threadedly connected to a threaded tube 14. The outer surface of the threaded tube 14 is installed with a movable plate 15. The front of the movable plate 15 is installed on the back of the lower pressure plate 5. The upper surface of the fixed plate 17 is equipped with a drive motor 16. The output end of the drive motor 16 is keyed to the top of the threaded rod 13.

[0026] like Figure 3 As shown, a movable block 18 is slidably connected inside the support plate 1. The movable block 18 is slid into the support plate 1. An mounting plate 19 is installed on the upper surface of the movable block 18. The movable block 18 moves backward, causing the mounting plate 19 to move backward. A fixing pin 20 is threaded through the upper surface of the movable block 18. The mounting plate 19 moves backward, causing the fixing piece 21 to move backward, moving the support piece 22 to the upper surface of the auxiliary block 3. After the movement is complete, the fixing pin 20 is inserted into the movable block 18. Then, the fixing pin 20 is rotated clockwise to press against the support plate 1. One end of the fixing pin 20 that passes through the movable block 18 presses against the support plate 1. The fixing piece 21 is installed on the upper surface of the mounting plate 19. The support piece 22 is installed on the back of the fixing piece 21. The function of the support piece 22 is to support the glass during heating and prevent the glass from deforming due to gravity after softening.

[0027] like Figure 2 As shown, a connecting hook 23 is provided on the outer surface of the support rod 4 located on the front side. The auxiliary rod 24 is manipulated to move outward along the fixed frame 26 to stretch the buffer spring 25, so that the connecting hook 23 is sleeved on the outer surface of the support rod 4 located on the front side. The auxiliary rod 24 is released, so that the buffer spring 25 contracts and drives the auxiliary rod 24 to move inward, so that the connecting hook 23 hooks the support rod 4. It should be noted that the function of the fixed frame 26 is to block the glass and prevent the glass from being taken away when the support piece 22 moves forward and is pulled out. The fixed frame 26 is placed higher than the thickness of the support piece 22, so the support piece 22 will not be blocked by the fixed frame 26 during the forward movement. The auxiliary rod 24 is installed on the inner side of the connecting hook 23, the buffer spring 25 is installed on the inner side of the auxiliary rod 24, and the fixed frame 26 is installed on the inner end of the buffer spring 25. The auxiliary rod 24 is slidably connected to the fixed frame 26.

[0028] In this embodiment, as Figure 1 As shown, a liquefied gas flame gun 27 runs through the interior of the fixing plate 17. It should be noted that the liquefied gas flame gun 27 is a common flame gun on the market. The rear end of the liquefied gas flame gun 27 is connected to an external liquefied gas storage tank through a hose, so that the flame sprayed by the liquefied gas flame gun 27 can heat and soften the surface of the explosion-proof glass. A support leg 28 is installed on the lower surface of the support plate 1.

[0029] In this embodiment, the movable block 18 slides along the support plate 1, and the movable block 18 moves backward, causing the mounting plate 19 to move backward. The mounting plate 19 moves backward, causing the fixing piece 21 to move backward. The fixing piece 21 moves backward, causing the support piece 22 to move backward, so that the support piece 22 moves to the upper surface of the auxiliary block 3. The fixing pin 20 is inserted into the movable block 18, and then the fixing pin 20 is rotated clockwise to press against the support plate 1, moving the fixing frame 26 to the inside of the support rod 4 located on the front side. The connecting hook 23 is moved outward, causing the auxiliary block 3 to move backward. The rod 24 moves outward, and the auxiliary rod 24 moves outward along the inside of the fixed frame 26. The outward movement of the auxiliary rod 24 stretches the buffer spring 25, so that the connecting hook 23 moves to the surface of the support rod 4 located on the front side. Then, the auxiliary rod 24 is released, so that the buffer spring 25 contracts and drives the auxiliary rod 24 to move inward. The inward movement of the auxiliary rod 24 drives the connecting hook 23 to move inward. The connecting hook 23 hooks the support rod 4 located on the front side, and the glass is placed on the upper surface of the support plate 22. The liquefied gas torch 27 is turned on to heat and soften the glass.

[0030] Once the glass is hot-bent, loosen the fixing pin 20 counterclockwise, manipulate the moving block 18 to move forward along the support plate 1. The moving block 18 moves forward, causing the mounting plate 19 to move forward. The mounting plate 19 moves forward, causing the fixing piece 21 to move forward. The fixing piece 21 moves forward, causing the support piece 22 to move forward. The support piece 22 moves forward and is pulled out from under the glass, so that the glass is blocked by the fixing frame 26. Repeat the above steps of setting the fixing frame 26, and then remove the fixing frame 26. At this time, there is no obstruction directly under the pressure plate 5.

[0031] The heating wire 10 is energized to generate heat. The auxiliary fan 11 is then activated, and its output rotates to blow air into the ventilation duct 9. This allows the air to pass through the heating wire 10, carrying away the heat. The air is then exhausted along the ventilation duct 9, with most of the heat remaining at the top of the duct. The drive motor 16 is then activated, and its output rotates, causing the threaded rod 13 to rotate. The rotation of the threaded rod 13 causes the threaded tube 14 to move downwards along its surface. The downward movement of the threaded tube 14 causes the moving plate 15 to move downwards, which in turn causes the lower pressure plate 5 to move downwards. The lower pressure plate 5 moves downwards along the support rod 4, causing the lower pressure block 6 to move downwards. The downward movement of the pressing block 6 causes the first heat-conducting plate 7 to move downward, which in turn causes the second heat-conducting plate 8 to move downward. The second heat-conducting plate 8 moves downward and passes through the connecting hole to fit onto the outer surface of the ventilation pipe 9, allowing the heat from the ventilation pipe 9 to be transferred to the second heat-conducting plate 8. The second heat-conducting plate 8 then transfers the heat to the surface of the first heat-conducting plate 7, thus preheating the pressing block 6. After the second heat-conducting plate 8 is fitted onto the surface of the ventilation pipe 9, it can continue to move downward. Furthermore, after the second heat-conducting plate 8 is fitted onto the ventilation pipe 9, there is still a distance between the pressing block 6 and the glass, allowing for preheating of the pressing block 6. The downward movement of the pressing block 6, in conjunction with the auxiliary block 3, performs hot bending of the glass.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
