DETAILED DESCRIPTION
[0049] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.
[0050] See also Figure 1 , is a tempered glass bending and forming device disclosed in an embodiment of the present application. The bending and forming device consists of a forming workbench 11, a pressure bellows 12, a driving cylinder 13 and an arc forming rod 14. Specifically, the forming workbench 11 is installed on the tempered glass axis bending and forming production system and is located behind the heating part.
[0051] There are multiple pressure bellows 12 and they are arranged in sequence along the material moving direction on the forming workbench 11. For example, if the material (heated tempered glass) on the forming workbench 11 flows from left to right, the pressure bellows 12 on the forming workbench 11 are arranged in sequence from left to right. The pressure bellows 12 are slidably connected to the forming workbench 11, and each pressure bellows 12 can slide independently on the forming workbench 11, and adjacent pressure bellows 12 are connected.
[0052] For some possible implementations, see Figure 2 A connecting pipe is provided on the leftmost pressure bellows 12 or the rightmost pressure bellows 12. An air flow hole is provided on the leftmost and rightmost pressure bellows 12, and two air flow holes are provided on the remaining pressure bellows 12, and adjacent air flow holes can connect two adjacent pressure bellows 12.
[0053] This can ensure that the multiple pressure bellows 12 can always remain in a connected state while moving, and the airflow input from the outside can be delivered to each pressure bellows 12.
[0054] See also Figure 3 The two sets of driving cylinders 13 are respectively arranged at the inflow end and the outflow end of the forming workbench 11, for example, at the left end and the right end of the forming workbench 11 mentioned above.
[0055] There are multiple groups of arc-shaped forming rods 14. In some possible implementations, there are two arc-shaped forming rods 14 in each group. The two ends of the two arc-shaped forming rods 14 are respectively connected to the corresponding driving cylinders 13 and can perform linear reciprocating motion under the action of the driving cylinders 13.
[0056] See also Figure 2 The arc-shaped forming rod 13 is parallel to the material moving direction on the forming workbench 11 and sequentially passes through the guide slot 126 on each pressure bellows 12, which can drive the position of all pressure bellows 12 to change. The working surface of the pressure bellows 12 is evenly distributed with air holes 15, and the function of the air holes 15 is to apply pressure to the tempered glass below to change the shape of the tempered glass.
[0057] The curvature radii of the arc forming rods 14 in different groups are different. During the production process, only one group of arc forming rods 14 will directly contact the pressure bellows 12, that is, the curved surface where the working surface of the pressure bellows 12 is located will change as the production process progresses.
[0058] See also Figure 4 For example, the deformation process of the entire tempered glass is divided into five stages, and there are five groups of corresponding arc-shaped forming rods 14. In the first stage, the first group of arc-shaped forming rods 14 are in direct contact with all the pressure bellows 12, driving the position of the pressure bellows 12 to change. At this time, the curvature radius of the curved surface where the working surface of all the pressure bellows 12 is located is R1.
[0059] In the second stage, the second group of arc-shaped forming rods 14 replaces the first group of arc-shaped forming rods 14 to directly contact all the pressure bellows 12. At this time, the curvature radius of the curved surface where the working surface of all the pressure bellows 12 is located is R2.
[0060] In the third stage, the third group of arc-shaped forming rods 14 replaces the second group of arc-shaped forming rods 14 to directly contact all the pressure bellows 12. At this time, the curvature radius of the curved surface where the working surface of all the pressure bellows 12 is located is R3.
[0061] By analogy, as the deformation process of the tempered glass proceeds, the curvature radius of the curved surface where the working surface of all the pressure bellows 12 is located is continuously reduced. During the whole process, the distance between the working surface of the pressure bellows 12 and each part of the tempered glass whose shape is constantly changing can always be kept uniform, so that the wind pressure at each part of the tempered glass during the deformation process can be kept consistent.
[0062] This can not only make the tempered glass deform evenly and stably, but also effectively reduce the probability of wind spots, and help to make the transition even across the tempered glass.
[0063] See also Figure 5As a specific embodiment of the tempered glass bending and forming device provided in the application, the pressure bellows 12 is composed of a bellows body 121, a partition ring 122, a first wind chamber 123, a second wind chamber 124 and a variable diameter air duct 125, etc. Specifically, the bellows body 121 is slidably connected to the forming workbench 11, and can slide on the forming workbench 11 driven by the arc forming rod 14, and the partition ring 122 divides the space in the bellows body 121 into a first wind chamber 123 and a second wind chamber 124. The first wind chamber 123 is connected to the wind hole 15, and the second wind chamber 124 is connected to the second wind chamber 124 on the adjacent pressure bellows 12.
[0064] The variable diameter air duct 125 is located in the first air chamber 123, with a first end close to the partition ring 122 and a second end close to the air hole 15. In the direction from the partition ring 122 to the air hole 15, the outer diameter of the variable diameter air duct 125 tends to increase.
[0065] When the air in the second air chamber 124 flows into the first air chamber 123 , it will be guided through the variable diameter air duct 125 . The main purpose of the guidance is to allow a part of the air flow to flow to the edge of the first air chamber 123 .
[0066] For further information, see Figure 5 An air guide plate 127 is added to the end of the variable diameter air duct 125 with a larger diameter. The air guide plate 127 is evenly distributed with guide holes 128. The air guide plate 127 can exert a certain resistance on the air flowing in the variable diameter air duct 125, so that the air flow distribution in the variable diameter air duct 125 is more uniform, and then flows out through the guide holes 128.
[0067] For further information, see Figure 5 The end with a smaller diameter on the variable diameter air duct 125 can extend into the partition ring 122, so that a part of the air flow can flow to the edge of the first air chamber 123 under the guidance of the outer wall of the variable diameter air duct 125, which can further improve the uniformity of air flow distribution.
[0068] Furthermore, the widths of the gaps between the smaller diameter end of the variable diameter air duct 125 and the inner wall of the partition ring 122 are all consistent.
[0069] See also Figure 6 The variable diameter air duct 125 recorded in the above content can make the air flowing into the first air chamber 123 from the second air chamber 124 be evenly distributed at the center and edge of the first air chamber 123, and then evenly flow out from the air hole 15. At the same time, the air guide plate 127 is used to reduce the flow rate of the airflow flowing out from the inside of the variable diameter air duct 125 so that it can be consistent with the flow rate of the airflow flowing along the outer wall of the variable diameter air duct 125.
[0070] See also Figure 7As a specific embodiment of the tempered glass bending and forming device provided in the application, there are multiple independent spaces in the first wind chamber 123 and the second wind chamber 124. The independent space in the first wind chamber 123 and the corresponding independent space in the second wind chamber 124 are connected, and a variable diameter air duct 125 is provided in each independent space in the wind chamber 123.
[0071] This can make the airflow distribution more uniform in the direction perpendicular to the flow of the logistics on the forming workbench 11. It should be understood that the tempered glass has a certain width, which will also make the length of the pressure bellows 12 much greater than its own width. The pressure bellows 12 of this structure has defects in airflow uniformity. After optimizing the space in the pressure bellows 12, this problem can be fundamentally solved.
[0072] In some possible implementations, the cross-sectional shapes of the first air chamber 123 and the second air chamber 124 are both square.
[0073] See also Figure 1 As a specific embodiment of the tempered glass bending and forming device provided in the application, a forming slide 21, a rotating roller 22, a deformation cylinder 23 and an arc-shaped deformation rod 24 are further added. There are multiple forming slides 21, and these forming slides 21 are arranged in sequence along the material flow direction on the forming workbench 11 and are slidably connected to the forming workbench 11. The rotating roller 22 is installed on the forming slide 21 and is rotatably connected to the forming slide 21. Each forming slide 21 is installed with at least one rotating roller 22.
[0074] In some possible implementations, the rotating roller 22 is driven by a motor, and each forming slide 21 is equipped with a motor, and the power output by the motor is transmitted to the rotating roller 22 via a sprocket or a pulley.
[0075] Two groups of deformation cylinders 23 are also provided at the inflow end and the outflow end of the forming workbench 11. The number of the deformation cylinders 23 is equal to the number of the arc-shaped deformation rods 24. The two ends of each arc-shaped deformation rod 24 are respectively connected to the pistons of the corresponding deformation cylinders 23 in the two groups of deformation cylinders 23.
[0076] See also Figure 8 The arc-shaped deformation rod 24 is parallel to the material moving direction on the forming workbench 11, and can push the forming slide 21 to move in the vertical direction. In addition, the arc-shaped deformation rod 24 also passes through the position guide hole 211 on each forming slide 21 in sequence.
[0077] The arc-shaped deformable rods 24 are divided into multiple groups, and the curvature radius of the arc-shaped forming rods 14 in different groups are different. During the production process, only one group of arc-shaped deformable rods 24 contacts the forming slide 21 to promote the fixed surface composed of multiple forming slides 21 to change.
[0078] The fixed surface formed by the forming slide 21 is a curved surface, which is also designed to match the bending of the tempered glass. The radius of curvature of the fixed surface formed by the forming slide 21 will also change with the deformation process of the tempered glass. For example, as mentioned above, the deformation process of the tempered glass is divided into five stages, so there are five groups of arc-shaped deformation rods 24. In each stage, one group of arc-shaped deformation rods 24 drives the positions of multiple forming slides 21 to be adjusted. Fig. 9 .
[0079] The fixed surface formed by the molding slide 21 can be regarded as a molding surface, which can change with the deformation of the tempered glass and guide the deformation trajectory of the tempered glass to match the final target trajectory. Compared with the deformation method of hanging down, this guided deformation can make the changes of various parts of the tempered glass more uniform.
[0080] For further information, see Figure 4 and Fig. 9 The number of groups of arc-shaped deforming rods 24 is the same as the number of groups of arc-shaped forming rods 14 , and the curvature radius of each group of arc-shaped deforming rods 24 is the same as the curvature radius of the corresponding group of arc-shaped forming rods 14 .
[0081] The embodiment of the present application also discloses a tempered glass axis bending production system, including any tempered glass bending device described in the above content.
[0082] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
