[0014] The present invention provides a hot-bent glass large-bending-degree processing and forming machine. It has the following beneficial effects:

[0015] 1. In this hot-bent glass large-bending-degree processing and forming machine, the driving shaft of the first motor drives the worm to rotate, the rotation of the worm drives the hollow worm wheel to rotate, the rotation of the hollow worm wheel drives the rotating shell to rotate, the rotation of the rotating shell drives the fixing component to rotate, the fixing component drives the glass to rotate, and due to the characteristics of the worm and the first motor, the torque will not be reversely transmitted to the worm, and the main load is in the vertical direction. The glass can maintain a fixed position when rotating to a specified position, preventing displacement during bending and affecting the bending process. The limiting slideway is used to guide and limit the connecting bracket, so as to ensure the stability of the connecting bracket during rotation.

[0016] 2. The hot-bending glass large-bending-degree processing and forming machine is equipped with an air extraction pump to extract air. The air passes through the vacuum suction cup and the hollow telescopic rod and reaches the inside of the connecting pipe through the first air pipe, causing a negative pressure to form inside the vacuum suction cup, thereby generating an attractive force on the glass and enabling the glass to be stably attracted to the top of the vacuum suction cup.

Through the cooperation between multiple groups of hollow telescopic rods, the curved glass can also be fixed to the top of the vacuum suction cup. It realizes the fixation of glass with different curved surfaces, thereby improving the versatility of the equipment.

[0017] 3. The hot-bending glass large-bending-degree processing and forming machine is equipped with the movable end of the hollow telescopic rod driving the connecting ring to descend. The connecting ring drives the pressing support to descend. The descent of the pressing support drives the movable end of the first hydraulic rod to descend. The descent of the movable end of the first hydraulic rod drives the hydraulic oil inside the first hydraulic rod to be transmitted to the inside of the second hydraulic rod through the oil pipeline. Since the cross-sectional area of the fixed end of the first hydraulic rod is larger than that of the fixed end of the second hydraulic rod, when the hydraulic oil inside the first hydraulic rod enters the inside of the second hydraulic rod through the oil pipeline, the second hydraulic rod extends under the action of the same volume of hydraulic pressure. The movable end of the second hydraulic rod drives the air collection box to descend. The descent of the air collection box drives the pressing frame to descend. The pressing frame descends under the sliding action of the connecting sliding frame and the pressing base, thereby driving the suction cup assembly to descend. The descent of the suction cup assembly fixes the upper surface of the glass. The specific principle is the same as that of the suction cup assembly. It realizes the fixation of the upper surface of the glass and, through the cooperation between the first hydraulic rod and the second hydraulic rod, enables the glass to be in a self-locking state under the action of gravity, thereby maintaining the stability of the glass during bending.

[0018] 4. The hot-bending glass large-bending-degree processing and forming machine is equipped with gas being input through the gas pipeline and ignited. Oxygen is input through the oxygen pipeline and ejected through the annular air duct, enabling oxygen and gas to be mixed and burned at the bottom of the ignition nozzle, so that the heat directly acts on the surface of the glass and raises the temperature, thereby softening the glass for bending. It realizes the heating and softening of the glass, and by increasing the contact area between gas and oxygen through the annular outlet, the combustion efficiency is improved, and thus the heating efficiency is enhanced.

[0019] 5. The hot-bending glass large-bending-degree processing and forming machine is provided with a roller shaft that rolls and drives the rotating shaft seat to move upward under the pressure provided on the upper surface of the glass. The upward movement of the rotating shaft seat drives the spring piece to deform. The deformation of the spring piece provides a reaction force to drive the roller shaft to move downward. The downward movement of the roller shaft squeezes the glass to position the glass. And the rotation direction of the roller shaft is perpendicular to the sliding direction of the fixed seat and the sliding seat. When the glass is bent, the second motor is started. The driving shaft of the second motor rotates to drive the moving bracket to rotate. The rotation of the moving bracket drives the sliding seat to slide along the fixed seat. The sliding of the sliding seat drives the rotating plate to slide. The sliding of the rotating plate drives the fixed bracket to slide. Since the rotation direction of the roller shaft is perpendicular to the sliding direction of the sliding seat and the fixed seat, the glass is driven to move, so as to heat different positions of the glass. After the glass is heated, the stepping motor is started. The driving shaft of the stepping motor drives the rotating plate to rotate. The rotation of the rotating plate drives the pressing top plate to move, so as to apply a force in the vertical direction to the glass, so that the glass is bent after heating, and different curvatures of bending are carried out under the cooperation of the second motor and the stepping motor. The bending of the glass is realized and different processing requirements are carried out according to the actual situation. BRIEF DESCRIPTION OF THE DRAWINGS

The side of the fixed bottom plate 301 is fixedly connected with the side of the conveyor belt 2. One side of the top of the fixed bottom plate 301 is fixedly connected with the bottom of the heating device 4.

[0034] The glass is placed inside the fixing component 309 and fixed. When the glass is rotated, the first motor 306 is started. The drive shaft of the first motor 306 drives the worm 305 to rotate. The rotation of the worm 305 drives the hollow worm gear 304 to rotate. The rotation of the hollow worm gear 304 drives the rotating housing 303 to rotate. The rotation of the rotating housing 303 drives the fixing component 309 to rotate. The fixing component 309 drives the glass to rotate.

Through the cooperation between multiple groups of hollow telescopic rods 3093, the curved glass can also be fixed on the top of the vacuum suction cup 30943. It realizes the fixation of glass with different curved surfaces, thereby improving the versatility of the equipment.

The descent of the movable end of the first hydraulic rod 30951 drives the hydraulic oil inside the first hydraulic rod 30951 to be transmitted to the inside of the second hydraulic rod 30955 through the oil pipeline 30954. Since the cross-sectional area of the fixed end of the first hydraulic rod 30951 is larger than that of the fixed end of the second hydraulic rod 30955, when the hydraulic oil inside the first hydraulic rod 30951 enters the inside of the second hydraulic rod 30955 through the oil pipeline 30954, the second hydraulic rod 30955 extends under the action of the same amount of hydraulic pressure. The movable end of the second hydraulic rod 30955 drives the gas collecting box 30963 to descend. The descent of the gas collecting box 30963 drives the pressing-down frame 30961 to descend. The pressing-down frame 30961 descends under the sliding action of the connecting sliding frame 30965 and the pressing-down base 30966, thereby driving the suction cup component 30962 to descend. The descent of the suction cup component 30962 fixes the upper surface of the glass. The specific principle is the same as that of the suction cup device 3094. The fixation of the upper surface of the glass is realized, and through the cooperation between the first hydraulic rod 30951 and the second hydraulic rod 30955, the glass is in a self-locking state under the action of gravity, so as to keep the glass stable during bending.

The roller shaft 5094 rolls and drives the rotating shaft seat 5093 to move upward under the pressure provided by the upper surface of the glass. The upward movement of the rotating shaft seat 5093 drives the spring piece 5092 to deform. The deformation of the spring piece 5092 provides a reaction force to drive the roller shaft 5094 to move downward. The downward movement of the roller shaft 5094 squeezes the glass to position the glass. And the rotation direction of the roller shaft 5094 is perpendicular to the sliding direction of the fixed seat 501 and the sliding seat 503. When the glass is bent, the second motor 502 is started. The drive shaft of the second motor 502 rotates to drive the moving bracket 504 to rotate. The rotation of the moving bracket 504 drives the sliding seat 503 to slide along the fixed seat 501. The sliding of the sliding seat 503 drives the rotating plate 507 to slide. The sliding of the rotating plate 507 drives the fixing frame 508 to slide. Since the rotation direction of the roller shaft 5094 is perpendicular to the sliding direction of the sliding seat 503 and the fixed seat 501, the glass is driven to move, so as to heat different positions of the glass. After the glass is heated, the stepping motor 506 is started. The drive shaft of the stepping motor 506 drives the rotating plate 507 to rotate. The rotation of the rotating plate 507 drives the pressing top plate 5091 to move, so as to apply a force in the vertical direction to the glass, so that the glass is bent after heating, and different curvatures of bending are carried out under the cooperation of the second motor 502 and the stepping motor 506. The bending of the glass is realized and different processing requirements are carried out according to the actual situation.
