[0002] The large-diameter disc-type hot bending glass processing equipment is a specialized device for producing large-size, complex-shaped hot-bent glass. It heats the glass to its softening temperature, uses molds and external force to bend it into shape, and then performs annealing treatment to ensure the stability and optical properties of the glass. The equipment typically includes key components such as a hot bending furnace, support device, pushing device, and traction device. It is widely used in the fields of construction, automobiles, and electronics to manufacture products such as building curtain walls, automobile windshields, and 3D mobile phone glass. "Large diameter disc type" refers to a specific structural design in the hot bending glass process equipment. Its core feature is the use of a large diameter disc-shaped mold or worktable to complete the hot bending process of glass.

A limit telescopic rod 25 is fixedly connected to one side of the electric telescopic rod 26. An arc-shaped plate 27 is fixedly connected to one end of the arc-shaped plate 27, and a connecting push plate 28 is fixedly connected to one end of the arc-shaped plate 27. The hot bending lower die assembly 4 includes a hot bending lower die body 41.

One end of the connecting push plate 28 is fixedly connected to the inner side of the hot bending upper die 3. The bottom end of the second hydraulic rod 43 is fixedly connected to one side of the lower end of the frame 1. The outer side of the arc-shaped built-in plate 61 is fixedly connected to the inner side of the lower end of the frame 1. The outer side of the rotating cylinder 64 is in contact with the outer side of the hot bending lower die body 41.
[0017] As a further implementation of this solution, the telescopic fixing assembly 5 includes an ear seat 51. A cylindrical rod 52 is fixedly connected to the inner side of the ear seat 51. The cylindrical rod 52 is rotatably connected to the inner side of a rotating opening 54. The rotating opening 54 is located inside the oil shell 53. A spring 55 is fixedly connected to the inner side of the oil shell 53. A sliding plate 56 is fixedly connected to one end of the spring 55. A hairpin holder 57 is fixedly connected to the inner side of the oil shell 53. An installation hole is provided inside the hairpin holder 57. A solenoid valve 58 is fixedly connected to the inner side of the hairpin holder 57. A double-column push rod 59 is slidably connected to the inner side of the oil shell 53. There are multiple ear seats 51. One end of the double-column push rod 59 is equipped with the cylindrical rod 52 and the ear seat 51. Sealing elements are fixedly connected to the outer sides of both the double-column push rod 59 and the sliding plate 56. The inner side of the oil shell 53 is hollow. The sealing rings on the outer sides of the slide plate 56 and the double column push rod 59 are all in contact with the inner side of the oil shell 53. The rotating port 54 penetrates the inner side of the oil shell 53. A through hole is opened on the inner side of the oil shell 53 near the rotating port 54. The oil shell 53 is connected to the rotating port 54 through the through hole. With the above settings, the telescopic fixing component 5 can freely extend or retract when the hot bending upper mold 3 and the hot bending lower mold assembly 4 are adjusted, without delaying the curvature adjustment of the hot bending upper mold 3 and the hot bending lower mold assembly 4. At the same time, after the hot bending upper mold 3 and the hot bending lower mold assembly 4 are adjusted, the strength of them is effectively improved by the fixing of the telescopic fixing component 5, preventing the hot bending upper mold 3 or the hot bending lower mold assembly 4 from deforming during the hot bending of glass. As a further implementation of this solution, the hot bending upper mold 3 is in the shape of a ring. The upper end of the hot bending upper mold 3 is located between the vertical plates 23. The inner side of the hot bending upper mold 3 is fixedly connected to the ear seat 51. There are two arc plates 27, and the arc plates 27 are arc-shaped. The middle solid plate 24 is located between the two arc plates 27. The limiting telescopic rods 25 are distributed near the four corners of the middle solid plate 24. One side of the electric telescopic rod 26 is fixedly connected to one side of the arc plate 27. The number of electric telescopic rods 26 is the same as the number of arc plates 27. With the above settings, the curvature of the lower end of the hot bending upper mold 3 can be quickly adjusted by the drive adjustment component 2. This operation is convenient and quick, and at the same time, it can ensure the accuracy and quality of glass hot bending. As a further implementation of this solution, the hot bending lower die body 41 is arc-shaped, with extension blocks fixed at both ends. The connecting pull plate 42 is embedded in the inner side of the movable groove 62. The outer side of the hot bending lower die body 41 is fixedly connected to the ear seat 51, and one side of the arc-shaped inner plate 61 is fixedly connected to the ear seat 51. Through the above settings, the cooperation between the hot bending lower die assembly 4 and the auxiliary assembly 6 facilitates the deformation of the hot bending lower die body 41 under pressure, thereby achieving the effect of curvature adjustment. At the same time, it can greatly reduce the friction force when the hot bending lower die body 41 is adjusted, and improve the service life of the hot bending lower die body 41.
[0018] Workflow: When adjusting the device during the hot bending of glass with different curved surfaces, the curvature of the upper hot bending mold 3 is first adjusted. At the same time, two electric telescopic rods 26 are activated. The electric telescopic rods 26 drive the curved plate 27 and the connecting push plate 28 to move respectively. Meanwhile, multiple limiting telescopic rods 25 extend. The limiting telescopic rods 25 can improve the stability of the curved plate 27 when it moves. The pushing force of the two connecting push plates 28 can cause deformation of the upper hot bending mold 3. The upper hot bending mold 3 is made of stainless steel and has a certain degree of flexibility. When the upper hot bending mold 3 deforms, multiple telescopic fixing components 5 retract. At this time, multiple solenoid valves 58 near the upper hot bending mold 3 are in the open state. After the curvature of the upper hot bending mold 3 is adjusted, the multiple solenoid valves 58 near the upper hot bending mold 3 are closed, thereby achieving the function of supporting the upper hot bending mold 3, improving the strength of the upper hot bending mold 3, and preventing the upper hot bending mold 3 from deforming during the hot bending of glass. To adjust the curvature of the hot bending lower die assembly 4, the second hydraulic rod 43 is activated, causing the connecting pull plate 42 to move downwards. The connecting pull plates 42 move in opposite directions, and their ends retract inwards. The extension blocks at both ends of the hot bending lower die body 41 prevent it from detaching from the rotating drum 64. As the hot bending lower die body 41 moves, its outer side is in contact with the outer side of the rotating drum 64. At this time, the rotating drum 64 rotates outside the roller of the support arm 63. Through the compression of the two rotating drums 64, the curvature of the hot bending lower die body 41 is adjusted. When the curvature of the hot bending lower mold assembly 4 is adjusted, multiple telescopic fixing components 5 near the hot bending lower mold assembly 4 contract, and multiple solenoid valves 58 are in the open state. After the curvature of the hot bending lower mold body 41 is adjusted, the solenoid valves 58 are closed at the same time. At this time, the shape of the hot bending lower mold body 41 will be fixed, which will improve the strength of the hot bending lower mold body 41 and prevent the hot bending lower mold body 41 from deforming during the hot bending of the glass, thereby improving the quality of the hot bending of the glass. After the adjustment is completed, the glass is heated to near its softening point by using an electric heating hot bending furnace to make it plastic, and then the device is used for bending and shaping. When the telescopic fixing assembly 5 retracts, the double-column push rod 59 moves into the oil shell 53. The oil shell 53 is filled with hydraulic oil, which is located between the double-column push rod 59 and the slide plate 56. When the double-column push rod 59 moves, the hydraulic oil squeezes the slide plate 56 through the solenoid valve 58, and the spring 55 deforms. At this time, the air inside the oil shell 53 flows out through the through hole and the pivot port 54. Through the elastic force of the spring 55, a force is applied to the slide plate 56 to move in the direction of the double-column push rod 59. When the solenoid valve 58 is closed, the position between the double-column push rod 59 and the oil shell 53 will be fixed. Based on the above principles, the device can perform hot bending on various curved glass surfaces, and the device is easy and quick to adjust, improving the accuracy and quality of glass hot bending.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
