[0061] The glass forming device and glass hot bending equipment according to the present application are described below with reference to the accompanying drawings.

[0062] like Figure 1-8 As shown, the present application proposes a glass forming device, including a preforming mechanism 4 and a final forming mechanism 2 arranged in parallel; wherein the preforming mechanism 4 includes a preheating and insulation furnace 40 and a hollow lower mold 402 arranged in the preheating and insulation furnace 40, the hollow lower mold 402 has an open end for supporting a glass plate 7, the end wall of the open end is concave into a contoured arc surface, and an auxiliary heating component 41 capable of heating the glass plate 7 into a spherical semi-finished glass is arranged in the hollow lower mold 402; the final forming mechanism 2 includes a shaping upper mold 21, the bottom surface of the shaping upper mold 21 is a convex spherical surface 211 with an adsorption function, and the convex spherical surface 211 is adapted to the curvature of the finished glass.

[0063] The present application sets a hollow lower mold 402 in the furnace body of the preheating and heat preservation furnace 40. The hollow lower mold 402 has an open end for supporting the glass plate 7. The end wall of the open end is concave to form a contoured arc surface. The hollow lower mold 402 is also provided with an auxiliary heating component 41. In this way, the open end structure of the contoured arc surface of the hollow lower mold 402 and the auxiliary heating component 41 are used to heat the glass plate 7, so that the glass plate 7 supported on the open end of the hollow lower mold 402 is softened by its own gravity and preformed into a spherical semi-finished glass that matches the contoured arc surface. Then, the shaping upper mold 21 in the final forming mechanism absorbs the spherical semi-finished glass and forms it into a finished glass. In the process of glass plate forming, the self-weight preforming and adsorption final forming combined in the present application do not require direct contact between the external mold and the glass plate, thereby avoiding the problems of indentation, imprinting, and glass breakage on the glass plate.

[0064] In some embodiments, Figure 2 and Figure 3 As shown, the preforming mechanism 4 includes a preheating and holding furnace 40, a preheating assembly 42 and an auxiliary heating assembly 41; the preheating and holding furnace 40 includes a furnace body 401 and a hollow lower mold 402 arranged in the furnace body 401, the hollow lower mold 402 has an open end for supporting the glass plate 7, and the end wall of the open end is concave to form a contoured arc surface; the preheating assembly 42 is arranged above the furnace body 401; the auxiliary heating assembly 41 is arranged in the hollow lower mold 402 and is located below the glass plate 7, and the auxiliary heating assembly 41 and the preheating assembly 42 cooperate to act on the area of ​​the glass plate 7 corresponding to the contoured arc surface.

[0065] The hollow lower mold 402 is a metal concave mold hollowed out in the middle, which is installed on the bottom wall of the furnace body 401. The upper end of the hollow lower mold 402 has an open end for supporting the glass plate 7, and the end surface of the open end is a concave contoured arc surface; on the one hand, it is used to guide the self-weight bending of the glass plate 7 after being heated and softened during the self-weight preforming process of the glass plate 7 and to support the edge arc surface; on the other hand, it is used to support the softened spherical semi-finished glass during the transfer process and the forming process. The auxiliary heating component 41 is distributed below the contoured arc surface, which is used to perform auxiliary heating on the bottom surface of the glass plate 7 supported on the contoured arc surface and to maintain the temperature of the softened spherical semi-finished glass during the transfer process.

[0066] The present application adopts a self-weight preforming forming method, and utilizes the open end structure of the contoured arc surface of the hollow lower mold 402, as well as the auxiliary heating component 41 and the preheating component 42 to heat the upper and lower surfaces of the glass plate 7 respectively, so that the glass plate 7 supported on the open end of the hollow lower mold 402 is softened by its own gravity and preformed into a spherical semi-finished glass that is compatible with the contoured arc surface. In this way, during the preforming process of the glass plate 7, there is no need for an external mold to come into direct contact with the glass plate 7, thereby avoiding the problems of indentation, imprinting, and glass breakage on the glass plate 7.

[0067] In some embodiments, Figure 4 As shown, the furnace body 401 includes a bottom plate 4011, a water-cooled side plate 4012 and an insulation plate 4013; the water-cooled side plate 4012 is arranged on the bottom plate 4011, the number of the water-cooled side plates 4012 is multiple and they enclose a cavity, and the hollow lower mold 402 is located in the middle of the cavity; the insulation plate 4013 is arranged in contact with the inner wall of the cavity.

[0068] The water-cooled side plate 4012 is provided with a cooling water circuit and is connected to the cooling circulating water. The cavity enclosed by the multiple water-cooled side plates 4012 is closed on all sides to prevent the heat in the cavity from escaping to the outside of the cavity, and the parts outside the preheating and holding furnace 40 are water-cooled and insulated to ensure that the working temperature of the parts outside the preheating and holding furnace 40 is normal temperature. The heat insulation board 4013 is generally a board made of aluminum silicate + adhesive, with a temperature resistance of about 600°C. A layer of mirror sheet metal is often installed on its outer surface to buckle it on the water-cooled side plate 4012 to keep the preheating and holding furnace 40 warm and insulated.

[0069] In some embodiments, the hollow lower mold 402 includes a plurality of temperature measuring components 4021, each of which sequentially penetrates the water-cooled side plate 4012 and the heat insulation plate 4013 from the outside, and the measuring end of the temperature measuring component 4021 extends into the cavity. Preferably, the temperature measuring component 4021 is a temperature measuring thermocouple, which is used to monitor the air temperature in the cavity in real time.

[0070] In addition, a furnace door window is provided on the water-cooled side panel 4012. The furnace door window is made of high-temperature resistant and glare-proof tempered glass and is fixed to the water-cooled side panel 4012 by welding. It is used to observe the heating and self-weight falling of the glass plate 7 in the preheating and insulation furnace 40.

[0071] In some embodiments, a slide rail 4014 is provided on the bottom plate 4011 in the horizontal direction, and the auxiliary heating component 41 includes a refractory brick base 411 and a resistance wire assembly 412; the refractory brick base 411 is slidably disposed on the slide rail 4014, and the hollow lower mold 402 is supported on the refractory brick base 411, and the refractory brick base 411 forms an arc-shaped concave surface on one side facing the hollow lower mold 402; the resistance wire assembly 412 includes a plurality of resistance wires capable of independently controlling heating, and the plurality of resistance wires are arranged side by side and spaced apart in sequence on the arc-shaped concave surface of the refractory brick base 411.

[0072] The present application can control the output power of each resistance wire to control the output heat thereof, so as to control the softening degree of different regions and parts of the glass plate 7, thereby controlling the curvature of the curved surface and spherical surface generated by the glass plate 7 under the combined action of gravity and heat.

[0073] In some embodiments, the preheating component 42 includes a frame 421, a first lifting component 422 and a preheating infrared radiation array 423; the first lifting component 422 is disposed on the frame 421; the preheating infrared radiation array 423 is disposed below the frame 421 and connected to the lifting end of the first lifting component 422; the preheating infrared radiation array 423 can be covered or separated from the furnace body 401 during the lifting process.

[0074] After the glass plate 7 is placed on the hollow lower mold 402, the self-weight preforming process starts to run; the first lifting component 422 on the preheating component 42 drives the preheating infrared radiation array 423 to descend and cover the open part of the furnace body 401 to form a closed furnace cavity. The straight radiation tubes on the preheating infrared radiation array 423 are started and begin to emit infrared rays to perform infrared radiation heating on the upper surface of the glass plate 7. At the same time, in the auxiliary heating component 41, the high-power resistance wires arranged in sequence on the refractory brick base 411 are started synchronously, heated up and heated, and the bottom surface of the glass plate 7 is baked and heated. The preheating infrared radiation array 423 and the auxiliary heating component 41 cooperate to form an upper and lower heating array that can control the heating power in different areas, so that different heating powers can be set according to process requirements to control the heating temperature and heat softening degree of the glass plate 7 at different positions. Figure 3 As shown, in the self-weight preforming process, the curvature of the curved surface or spherical surface formed by the self-weight falling of the glass plate 7 at different positions and regions can be controlled during the self-weight falling process after softening. Through this self-weight preforming method, the glass plate 7 can be preformed by self-weight into a spherical semi-finished glass with a curvature of the curved surface and spherical surface very close to the convex curved surface of the final forming mechanism 2 through the preheating infrared radiation array 423 and the heating of the auxiliary heating component 41.

[0075] like Figure 6 As shown, the preheating infrared radiation array 423 includes a top plate anti-bending rib 4231, a preheating top plate 4232 and an infrared radiation component 4233 which are stacked in sequence from top to bottom; wherein the infrared radiation component 4233 includes a plurality of straight radiation tubes which are arranged in sequence in a horizontal direction.

[0076] Among them, the top plate anti-bending rib 4231 is composed of multiple long strips of different lengths that are cross-interlocked by multiple screws and installed on the top of the preheating top plate 4232. Each long strip is locked with the preheating top plate 4232 to prevent the preheating top plate 4232 from being deformed by its own gravity and the gravity of the mounted parts thereon.

[0077] The straight radiant tube can emit infrared rays to radiate and heat objects within the infrared coverage area. The straight radiant tube is installed on the preheating top plate 4232, and the power and temperature of each straight radiant tube are independently controlled. Therefore, the output power of each straight radiant tube can be controlled to control the output heat, so as to control the softening degree of different areas and parts of the glass plate 7, and further control the curvature of the curved surface and spherical surface of the glass plate 7 generated by gravity and heat falling.

[0078] In addition, the preheating infrared radiation array 423 also includes a water-cooling protection plate installed at the outlets of the two ends of the straight radiation tube. The water-cooling protection plate is made of a strip plate with an internal water channel and water-cooling pipes on the left and right sides of the top, and is used to protect the temperature of the outlets of the two ends of the infrared radiation tube. An anti-collision protection plate is also provided on the periphery of the infrared radiation component 4233. On the one hand, it is used to suspend and fix the preheating top plate 4232 and the water-cooling protection plate. On the other hand, it is used to protect the straight radiation tube when the preheating top plate 4232 falls due to a machine failure or improper operation by personnel, so as to prevent the straight radiation tube from directly colliding with other workpieces and thus being broken and damaged.

[0079] In some embodiments, the first lifting assembly 422 includes a lifting drive member 4221 and a guide rod 4222; the driving end of the lifting drive member 4221 movably passes through the top surface of the frame 421 and is connected to the top plate anti-bending rib 4231; the number of guide rods 4222 is multiple and they are arranged around the lifting drive member 4221, the bottom end of the guide rod 4222 is connected to the top plate anti-bending rib 4231, and a locking block 4223 is provided at the top.

[0080] Among them, the lifting drive member 4221 is a lifting cylinder, and the top surface of the top plate anti-bending rib plate 4231 is connected to the piston rod of the lifting cylinder through a floating joint. When the lifting cylinder drives the top plate anti-bending rib plate 4231 to move up and down, the guide rod 4222 guides the lifting movement through a linear bearing, thereby improving the stability of the top plate anti-bending rib plate 4231 during the lifting process and reducing the amplitude of left and right swinging. A locking block 4223 is also provided on the guide rod 4222 for safety protection to prevent the workstation from falling.

[0081] In some embodiments, Figure 7 and Figure 8As shown, the final forming mechanism 2 includes a shaping upper mold 21 and an upper mold heating mechanism; the bottom surface of the shaping upper mold 21 is a convex spherical surface 211 with an adsorption function, and a plurality of tiny vacuum pores are formed on the convex spherical surface 211. The shaping upper mold 21 is connected to a large vacuum pump in the outside world and can be adapted to adsorb the spherical semi-finished glass in the hollow lower mold 402; the convex spherical surface 211 bulges outward in a direction away from the shaping upper mold 21, and the convex spherical surface 211 is adapted to the curvature of the finished product; after the precision fine-tuning is completed, the vacuum pump connected to the shaping upper mold 21 is started, so as to provide a strong adsorption force for the plurality of vacuum pores on the convex spherical surface 211, and the upper mold heating mechanism (not shown) is located in the shaping upper mold 21 and can preheat the inside of the shaping upper mold 21. Preferably, the upper mold heating mechanism built into the shaping upper mold 21 can be a plurality of heating tubes, so as to achieve heating of the shaping upper mold 21.

[0082] In such Figure 5 As shown, the final forming mechanism 2 also includes an upper mold heating furnace 23, which is rigidly connected to the preheating and insulation furnace 40 and can reciprocate along the conveying direction of the glass. The upper mold heating furnace 23 can move to the bottom of the shaping upper mold 21 or away from the shaping upper mold 21 within the moving stroke.

[0083] Among them, the upper mold heating furnace 23 includes a bottom plate, a side plate, a contoured infrared radiation array and a water cooling module; the side plates are arranged on the bottom plate and are in multiple numbers, and the multiple side plates and the bottom plate enclose a cavity with an open upper end, and the cavity structure closed on all sides can prevent the heat in the furnace from escaping to the outside of the furnace; the contoured infrared radiation array is arranged in the cavity and has a concave arc-shaped heating surface; the water cooling module is arranged on both sides of the contoured infrared radiation array, and the side plates are provided with multiple water inlets and outlets connected to the water cooling module.

[0084] Specifically, the profiling infrared radiation array is composed of a plurality of profiling radiation tubes that are shaped according to the convex spherical surface 211 of the final forming mechanism 2, wherein each profiling radiation tube independently controls the heating power and heating temperature. The plurality of profiling radiation tubes are used to heat the shaping upper mold of the final forming mechanism 2 synchronously during the self-weight preforming process; and when the final forming mechanism 2 is shaping the spherical semi-finished glass, the profiling infrared radiation array compensates the softening temperature of the final forming mechanism 2 and the spherical semi-finished glass being shaped. In addition, the shaping temperature of different areas and different parts of the shaping upper mold 21 can also be controlled by controlling the output power of a single profiling radiation tube to ensure the uniformity of the shaping temperature on the convex curved surface of the final forming mechanism 2.

[0085] In some embodiments, the final molding mechanism 2 also includes a second lifting assembly 22 disposed on the shaping upper mold 21. The second lifting assembly 22 is connected to the lifting drive of the shaping upper mold 21. The lifting movement of the shaping upper mold 21 is driven by the second lifting assembly 22 to achieve the purpose of closing the mold with the hollow lower mold 402 below.

The second lifting component 22 is a servo screw mechanism and includes a support seat 221, a rotating screw 222, a rotating drive member 223, a lifting connection seat 224, and a rotating nut 225; the support seat 221 is installed on the frame 24, and the support seat 221 is provided with a guide rail along the height direction; the rotating drive member 223 is rotatably connected to the rotating screw 222; the lifting connection seat 224 is provided on the forming plate group 25, and the lifting connection seat 224 is slidably matched with the guide rail; the rotating nut 225 is spirally sleeved on the rotating screw 222 and connected to the lifting connection seat 224.

[0087] Among them, the rotating drive part 223 is a rotating motor, which is used to drive the rotating screw 222 to rotate. The rotation of the rotating screw 222 can drive the rotating nut 225 to move in the height direction. Since the rotating nut 225 is connected to the lifting connecting seat 224, it drives the lifting connecting seat 224 to move up and down, thereby achieving the purpose of converting the rotational motion of the rotating screw 222 into linear motion.

[0088] In some embodiments, the number of the second lifting assemblies 22 is multiple and they are arranged at intervals at the corners of the forming plate group 25. The fixed end of each group of the second lifting assemblies 22 can be detachably connected to the frame body 24. The movable end of each group of the second lifting assemblies 22 is connected to an angle adjustment structure capable of multi-angle adjustment. The ends of some or all of the angle adjustment structures are also connected to a cross rail group 227.

[0089] The cross rail set 227 is connected to the corresponding corners; the angle adjustment structure not equipped with the cross rail set 227 is directly connected to the corresponding corners.

[0090] In some embodiments, the number of second lifting assemblies 22 is four groups, among which three groups of second lifting assemblies 22 have a movable end provided with a cross guide rail group 227 connected to the bottom of the lifting hinge seat 226, and the cross guide rail group 227 can slide in a horizontal plane relative to the forming plate group 25.

[0091] Among them, each group of cross-guide rail groups 227 includes a guide rail seat, two groups of guide rail sliders, an upper slider baffle, a lower slider baffle, and a capstan connecting plate. The two groups of guide rail sliders are respectively installed on the upper and lower parts of the guide rail seat and are installed in a cross shape. The upper guide rail slider is fixed on the capstan connecting plate, and the guide rail is fixed on the guide rail seat. The lower guide rail slider is fixed on the guide rail seat, and the guide rail is fixed on the forming top plate of the forming plate group 25. The upper slider baffle of the upper guide rail slider is installed and fixed on both sides of the guide rail seat. The lower slider baffle of the lower guide rail slider is installed and fixed on both sides of the guide rails of the upper and lower guide rail sliders of the forming top plate. The capstan connecting plate is locked with the capstan base by screws. Each group of cross-guide rail groups 227 can realize fine-tuning and movement in the x and y straight line directions of a corner of the forming top plate that is fixed to the guide rail of the lower guide rail slider.

[0092] In some embodiments, the angle adjustment structure includes a lifting hinge seat 226, and the lifting hinge seat 226 is pivotally connected to the bottom of the lifting connection seat 224. The lifting hinge seat 226 includes a hinge seat shaft and a fisheye joint, so that a large-scale rotation angle adjustment can be performed with the hinge seat shaft as the axis center, and a small-scale rotation angle adjustment can be performed with the floating connection ball inside the fisheye joint as the ball center.

[0093] In such Figure 8 Among the four groups of servo screw mechanisms shown: three groups of servo screw mechanisms are connected to the three corners of the upper forming top plate of the forming plate group 25 through three groups of "adjustment mechanisms of lifting capstans and cross guide rail groups 227 installed in series". Another group of servo screw mechanisms is directly connected to the last corner of the upper forming top plate of the forming plate group 25 through the lifting capstan. On the forming top plate, the three corners connected to the servo screw mechanisms are realized to perform small-amplitude fine-tuning movement in the x and y linear directions, large-amplitude angle adjustment with the capstan shaft as the axis center, and small-amplitude angle adjustment with the floating connection ball inside the fisheye joint as the ball center. The other connection angle can be adjusted in a large range of angles with the hinge shaft as the axis center, and in a small range of angles with the floating connection ball inside the fisheye joint as the ball center, thereby achieving adjustable horizontality of the bottom plate 4011 based on the preheating and insulation furnace 40 and the bottom plate based on the upper mold heating furnace 23 during the shaping and heating process of the shaping upper mold 21.

[0094] In addition, it should be noted that when the second lifting assembly 22 is used to adjust the height direction of the forming plate group 25, there are four lifting modes:

[0095] (1) Rapid lifting (manual / automatic mode)

[0096] When the glass forming device 2 controls the forming plate group 25 to perform long-distance lifting (single lifting stroke exceeds 50mm), the second lifting assembly 22 will adopt the "fast lifting" mode. During the "fast lifting" process, the four rotating motors open the brakes at the same time and run synchronously at the fastest speed; the four sets of servo screw mechanisms start running at the same time and lift synchronously, controlling the forming plate group 25 to reach the specified position at the fastest speed.

[0097] (2) Precision lifting (manual / automatic mode):

[0098] When the final forming mechanism 2 controls the forming plate group 25 to perform a short-distance lifting (single lifting stroke does not exceed 50mm), the second lifting component 22 will adopt the "precision lifting" mode. During the "precision lifting" process, the four rotary motors open the brakes at the same time and run synchronously at a slow speed; the four sets of servo screw mechanisms start running at the same time and perform lifting synchronously, controlling the forming plate group 25 to lift and lower to the specified position at a relatively slow and precise speed.

[0099] (3) Fine-tune the lifting and lowering (manual / automatic mode):

[0100] When the mold is replaced or the machine is used for a long time, if the horizontal parallelism between the molding plate group 25 and the hollow lower mold 402 fluctuates, people need to manually calibrate the parameters and points of the four servo screw mechanisms in a "fine-tuning lifting" manner through manual mode.

[0101] ① Before fine-tuning the lifting and lowering: First, manually operate and start the four rotating motors at the same time to control the rotating nuts 225 on the four servo screw mechanisms to "rapidly descend", thereby controlling the four corners of the forming plate group 25 to "rapidly descend"; thereby controlling the shaping upper mold 21 suspended on the forming plate group 25 to "rapidly descend" to a height close to the mold closing with the hollow lower mold 402 and maintain a certain distance. At this time, the height distances between the four corners of the forming plate group 25 and the placement surface of the glass plate 7 on the hollow lower mold 402 are "height 1", "height 2", "height 3" and "height 4" respectively.

[0102] ②. When fine-tuning the lifting and lowering: For the convenience of explanation, the four rotary motors are named rotary motor 1, rotary motor 2, rotary motor 3, and rotary motor 4, and the corresponding servo screw mechanisms are named servo screw mechanism 1, servo screw mechanism 2, servo screw mechanism 3, and servo screw mechanism 4, respectively.

[0103] I. The rotating motor 1 is turned off, the internal brake of the rotating motor is started, the rotating nut 225 of the servo screw mechanism 1 corresponding to the rotating motor 1 is fixed, and the "height 1" remains fixed accordingly.

[0104] II. The rotating motors 2, 3 and 4 start running at the slowest speed, and the internal brakes of the rotating motors are closed. The rotating nuts 225-2, 225-3 and 225-4 on the servo screw mechanism 2, 3 and 4 are respectively controlled to move a small distance.

[0105] III. Thus, the height distances between the upper left corner, lower left corner, upper right corner, and lower right corner of the forming plate group 25 and the placement surface of the glass plate 7 on the hollow lower mold 402 - "height 2", "height 3", and "height 4" - are all moved toward "height 1".

[0106] IV. When the height distances of the upper left corner, lower left corner, upper right corner and lower right corner of the forming plate group 25 and the placement surface of the glass plate 7 on the hollow lower mold 402 - "height 1", "height 2", "height 3" and "height 4" are all equal, the shaping upper mold 21 is parallel to the level of the placement surface of the glass plate 7 on the hollow lower mold 402.

[0107] V. Finally, the shaping upper mold 21 and the hollow lower mold 402 are molded together through manually controlled precise lifting, and the fine-tuning lifting is completed.

[0108] ③. After the fine-tuning and lifting are completed: record the data parameters during the fine-tuning and lifting process and save them in the touch screen of the device; the saved data parameters can be used to control the lifting mechanism on the glass forming device 2 to automatically fine-tune the lifting and lowering, and automatically calibrate the mold closing accuracy.

[0109] (4) Fully automatic lifting (fully automatic mode):

[0110] After the horizontal parallelism of the shaping upper mold 21 and the hollow lower mold 402 is finely adjusted by fine-tuning the lifting, the equipment enters the fully automatic lifting mode. During the fully automatic lifting process, each lifting movement includes the above three lifting modes - fast lifting, fine-tuning lifting, and precision lifting, and all are fully automatically controlled.

[0111] ① Before fully automatic lifting:

[0112] I. After the shaping upper die 21 is manually suspended and installed on the forming plate group 25, the shaping upper die 21 is "quickly lifted" to the "standby position" by controlling the four sets of servo screw mechanisms through manual mode operation. Figure 1 The position of the shaping upper mold 21 when the glass plate 7 is loaded is shown.

[0113] II. Manual mode operation is performed manually to control four sets of servo screw mechanisms to complete the calibration of the horizontal parallelism between the shaping upper mold 21 and the hollow lower mold 402 through "fine-tuning lifting (manual mode)".

[0114] III. After completing the calibration of horizontal parallelism, a mold closing test is performed. If the shaping upper mold 21 can be molded with the hollow lower mold 402, the shaping upper mold 21 is controlled to "rapidly lift" to the "standby position" by manual mode operation, and the whole machine enters the "full-automatic lifting" mode.

[0115] ②. When performing fully automatic lifting:

[0116] I. The glass plate 7 is manually loaded, and the shaping upper mold 21 and the forming plate group 25 are kept in the "standby position".

[0117] II. In the self-weight preforming / shaping upper mold 21 heating process: the preheating and holding furnace 40 moves to the self-weight preforming station, and the upper mold heating furnace 23 moves to the heating position of the shaping upper mold 21; the machine program automatically controls four sets of servo screw mechanisms to "quickly drop" the shaping upper mold 21 to the heating height position of the profiling infrared radiation array, and the profiling infrared radiation array starts heating.

[0118] III. After the self-weight preforming / shaping upper die 21 heating process is completed, the machine program automatically controls four sets of servo screw mechanisms to "quickly lift" the shaping upper die 21 to the "standby position".

[0119] IV. In the shaping process: after the preheating and holding furnace 40 moves to the shaping position, the machine program automatically controls the four sets of servo screw mechanisms to first "rapidly descend" to a height where the shaping upper mold 21 and the hollow lower mold 402 are close to the mold closing, but maintain a certain distance.

[0120] V. The machine program automatically controls four sets of servo screw mechanisms to make the shaping upper mold 21 complete the automatically controlled "fine adjustment lifting"; through the automatically controlled "precision descent", the shaping upper mold 21 is molded with the hollow lower mold 402. During the mold closing process, the vacuum adsorption function of the final molding mechanism 2 is turned on to provide vacuum adsorption force for the shaping upper mold 21 to complete the high-temperature adsorption of the spherical semi-finished glass.

[0121] VI. After the shaping process is completed: the machine program automatically controls four sets of servo screw mechanisms to make the shaping upper mold 21 and the finished glass or spherical semi-finished glass adsorbed thereon be first "precision lifted" and separated from the hollow lower mold 402, and then "quickly lifted" to the "standby position".

[0122] VII. Temperature compensation process (if there is no such process, the finished glass will be directly transferred to the cooling and retracting line process): the preheating and holding furnace 40 moves back to the self-weight preforming station, and the upper mold heating furnace 23 moves back to the heating position of the shaping upper mold 21; the machine program automatically controls the four sets of servo screw mechanisms to "rapidly drop" the spherical semi-finished glass adsorbed by it to the heating height position of the profiling infrared radiation array. The profiling infrared radiation array restarts heating to perform temperature compensation on the spherical semi-finished glass.

[0123] VIII. After the temperature compensation process is completed: the machine program automatically controls four sets of servo screw mechanisms to "quickly lift" the shaping upper mold 21 and the finished glass adsorbed thereon to the "standby position".

[0124] IX. In the process of resetting the furnace body 401 / transferring the finished glass to the cooling telescopic line: the machine program automatically controls the four sets of servo screw mechanisms to first "rapidly lower" the shaping upper mold 21 and the finished glass adsorbed thereon; to make the lower surface of the finished curved glass "rapidly lower" to a height position where it is about to contact the upper surface of the telescopic roller line extending from the cooling telescopic line, but still maintains a short distance. Then, the shaping upper mold 21 and the finished glass adsorbed thereon are "precisely lowered" to the lower surface of the finished glass, and "precisely lowered" to the "finished glass unloading position" where it fits the upper surface of the telescopic roller line but does not apply pressure.

[0125] The vacuum adsorption function of the final forming mechanism 2 is turned off, the vacuum is broken, and the shaping upper mold 21 places the finished glass on the telescopic roller line extending from the cooling telescopic line.

[0126] X. After the furnace body 401 is reset / the finished glass is transferred to the cooling telescopic line, the machine program automatically controls the four sets of servo screw mechanisms to "quickly lift" the shaping upper mold 21 to the "standby position". Then, the telescopic roller line on the cooling telescopic line is retracted to its original position.

[0127] Finally, the furnace body 401 is reset / the finished glass is transferred to the cooling telescopic line, and the subsequent finished glass cooling and discharging process is completed. The next round of production and the next round of fully automatic lifting action of the final forming mechanism 2 are repeated.

[0128] To sum up, the present application realizes precise adjustment of the mold closing of the hollow lower mold 402 and the shaping upper mold 21 through the second lifting assembly 22, so that the curvature of the finished curved glass finally obtained is closer to the target curvature, which is suitable for the production of large-size and ultra-large curvature finished curved glass.

[0129] Furthermore, if Fig.11 As shown, in order to prevent personnel from accidentally falling into or actively entering the upper mold heating furnace 23 heated to a high temperature due to various factors, and to prevent personnel loss and safety accidents, a protective cover device 51 is also provided. The protective cover device 51 includes a mounting frame 511 and a protective rib plate 512, a water cooling plate 513 and a protective heat insulation plate 514 which are arranged on the bottom surface of the mounting frame 511 and stacked from top to bottom, and a water cooling channel is provided inside the water cooling plate 513.

[0130] The protective ribs 512 are composed of a plurality of long strips of different lengths interlocked by a plurality of screws, and each of the long strips is detachably connected to the bottom surface of the mounting frame 511 to prevent the mounting frame 511 from being deformed by its own gravity and the gravity of the mounting parts thereon. The protective heat insulation board 514 and the water cooling board 513 form a protective heat insulation board group 514, which is used to provide heat insulation protection for the upper mold heating furnace 23 to prevent personal injury and safety accidents.

[0131] In addition, a fence is installed around the top of the mounting frame 511 to play a protective role. A protective guide rod 4222 and a lifting cylinder with an adjustable stroke are also provided on the top surface of the mounting frame 511. The protective guide rod 4222 passes through the mounting frame 511 and is connected to the protective rib plate 512. The lifting end of the lifting cylinder passes through the mounting frame 511 and drives the protective rib plate 512. When the lifting cylinder drives the protective rib plate 512 to move up and down, the protective guide rod 4222 guides the lifting movement. At the same time, in order to prevent the workstation from falling, an anti-fall locking block 4223 is also installed on the protective guide rod 4222 for safety protection.

[0132] A second aspect of the present application provides a glass hot bending device, comprising the above glass forming device and a glass cooling mechanism; the discharge end of the final forming mechanism 2 can be moved to dock with the glass cooling mechanism.

[0133] In some embodiments, the glass cooling mechanism includes a cooling telescopic line 31 and a cooling unloading line 32 arranged in sequence along the discharge direction of the finished curved glass, and the feeding end of the cooling telescopic line 31 can be moved to the bottom of the final forming mechanism 2.

[0134] The present application performs primary and secondary cooling of the finished curved glass by means of the cooling telescopic wire 31 and the cooling unloading wire 32, respectively, and adopts the method of air cooling while moving to the unloading position, thereby realizing the production of ultra-large-size ultra-large-curvature curved glass. When performing the primary cooling, the material-collecting end of the cooling telescopic wire 31 extends to the bottom of the final forming mechanism 2, and the finished curved glass adsorbed under the final forming mechanism 2 stops adsorption and falls onto the cooling telescopic wire 31 for primary cooling. After the primary cooling is completed, the finished curved glass moves along the cooling telescopic wire 31 to the cooling unloading wire 32 for secondary cooling, and the finished curved glass after the secondary cooling is manually unloaded at the discharge end of the cooling unloading wire 32.

[0135] like Fig. 9 and Fig.10As shown, the glass hot bending equipment also includes a conveying track 6, one end of which is connected to the loading station, and the other end passes through the preforming mechanism 4 and the final forming mechanism 2, so that the upper mold heating furnace 23 and the preheating and insulation furnace 40 connected in series can slide on the conveying track 6 and extend into the protective cover device 51; the upper mold heating furnace 23 and the preheating and insulation furnace 40 are both slidably arranged on the conveying track 6; when the shaping upper mold 21 is preheated, the upper mold heating furnace 23 moves to the protective cover device 51.

[0136] For ease of understanding, the entire glass forming process is described in detail below. Specifically, the glass forming process mainly includes the self-weight preforming process and the shaping process:

[0137] (1) Before the shaping process begins, the self-weight preforming and heating process of the shaping upper mold 21 needs to be completed:

[0138] Before the glass plate 7 is shaped, it will first undergo a self-weight preforming process to make the glass plate 7 fall down and become the required spherical semi-finished glass. At the same time, the profiling radiation tubes on the profiling infrared radiation array in the upper mold heating furnace 23 will irradiate and heat the convex spherical surface 211 of the shaping upper mold 21 with infrared radiation. In addition, the heating tube built into the shaping upper mold 21 is also started synchronously to heat the entire shaping upper mold 21, so that the temperature of the shaping upper mold 21 is raised to the softening temperature of the glass (generally about 500-800°C) before the shaping is performed, so as to prevent the shaping upper mold 21 in a low temperature state from absorbing the spherical semi-finished glass in a high temperature state during the shaping process, causing the spherical semi-finished glass to break.

[0139] (2) At the beginning of the shaping process, the moving mechanism needs to transfer:

[0140] After the self-weight preforming / shaping upper mold 21 heating process is completed, the preheating and insulation furnace 40 moves to the shaping station, and the upper mold heating furnace 23 moves to the protective cover device 51. In this process: the built-in heating tube in the shaping upper mold 21 will continue to operate to continuously heat and keep the shaping upper mold 21 warm. The contoured infrared radiation array in the upper mold heating furnace 23 will be turned off and the heating will stop. The auxiliary heating component 41 in the preheating and insulation furnace 40 will continue to heat, bake and keep warm the spherical semi-finished glass obtained by self-weight preforming, and prevent the spherical semi-finished glass from hardening due to heat loss.

[0141] (3) When the shaping process starts, the movement process of the final shaping mechanism 2 is:

[0142] After the preheating and holding furnace 40 is aligned with the final forming mechanism 2 , the final forming mechanism 2 controls the shaping upper mold 21 heated to the glass softening temperature to descend through the multiple servo screw mechanisms of the second lifting mechanism.

[0143] And through the fine-tuning function of multiple sets of servo screw mechanisms, according to the process requirements, the horizontality of the shaping upper mold 21 based on the bottom plate 4011 of the preheating and heat preservation furnace 40 is adjusted to ensure the mold closing accuracy of the shaping upper mold 21 and the hollow lower mold 402 and the fitting accuracy of the convex curved surface of the shaping upper mold 21 and the spherical semi-finished glass. After completing the precision fine-tuning, the large vacuum pump connected to the shaping upper mold 21 is started to provide a strong adsorption force and vacuum suction capacity for the tiny vacuum pores on the convex curved surface of the shaping upper mold 21. The final forming mechanism 2 will control the shaping upper mold 21 to continue to descend, and complete the adsorption and bonding with the spherical semi-finished glass placed in the preheating and heat preservation furnace 40 and on the hollow lower mold 402, which is being baked and heat-insulated by the auxiliary heating component 41.

[0144] After the adsorption and bonding is completed, the semi-softened spherical semi-finished glass will eventually be tightly attached to the convex surface of the shaping upper mold 21 under the strong adsorption force provided by the large vacuum pump for the convex surface of the shaping upper mold 21. Then all heating devices will be turned off to cool down, and the spherical semi-finished glass will be tightly attached to the convex surface of the shaping upper mold 21 after being shaped, and gradually cooled and solidified into a finished curved glass.

[0145] (4) After the shaping process is completed, the movement process of the temperature compensation process is:

[0146] When the spherical semi-finished glass has cooled and solidified before adsorption, or cooled and solidified before being completely formed during the adsorption process, and the spherical semi-finished glass cools and solidifies prematurely, the machine needs to be manually operated to make the machine enter the temperature compensation process. When the temperature compensation process starts, the final forming mechanism 2 will control the upper shaping mold 21 adsorbing the prematurely solidified spherical semi-finished glass through the group servo screw mechanism of the second lifting mechanism. The preheating and insulation furnace 40 returns to the self-weight preforming station, and the upper mold heating furnace 23 returns to the upper mold heating position. During this process, the preheating and insulation furnace 40 and the auxiliary heating components 41 and the preheating infrared radiation array 423 on the lower preheating device are all in a closed waiting state.

[0147] After the upper mold heating furnace 23 and the final forming mechanism 2 are aligned, the final forming mechanism 2 will control the shaping upper mold 21 to descend again through the four sets of servo screw mechanisms of the second lifting mechanism, and perform precision fine adjustment again. Then, the profiling radiation tubes on the profiling infrared radiation array in the upper mold heating furnace 23 will restart to heat the pre-cured spherical semi-finished glass adsorbed on the shaping upper mold 21.

[0148] When the pre-solidified spherical semi-finished glass adsorbed on the shaping upper mold 21 is reheated to soften, it will eventually fit tightly on the convex curved surface under the continuous action of the adsorption force of the convex curved surface of the shaping upper mold 21. Then all heating devices will be turned off again to cool down, and the pre-solidified spherical semi-finished glass will eventually fit tightly on the convex curved surface of the shaping upper mold 21 after secondary heating and softening, and secondary shaping, and gradually cool and solidify into finished glass.

[0149] It should be noted that if the spherical semi-finished glass does not cool and solidify prematurely, it will directly enter the finished glass cooling and expansion line process after the shaping process is completed.

[0150] (5) After the shaping or temperature compensation process is completed:

[0151] After the spherical semi-finished glass that has not been cooled and solidified prematurely is shaped, it will directly enter the cooling and expansion line process of the finished glass. If the spherical semi-finished glass is cooled and solidified prematurely, it will enter the cooling and expansion line process of the finished glass after the temperature compensation process.
