Description

Technical Field

[0001] This utility model relates to the field of curved glass forming technology, specifically to a curved glass forming device. Background Technology

[0002] Currently, glass manufacturers purchase various hard-axis bending tempering equipment to produce curved glass in more sizes. Among these, equipment for producing large-size curved tempered glass has a large footprint, high initial investment costs, and high operating costs, but its utilization rate is low. The reasons are as follows: (1) When large-size bending tempering equipment is used for bending and forming small and medium-sized glass, its forming accuracy is poor and it is difficult to meet the quality requirements of small and medium-sized glass. (2) The bending glass arc-changing system of the large-size bending tempering equipment is relatively long, and the glass takes a long time to reach the middle of the arc-changing system, resulting in a large temperature drop in the glass and affecting the forming quality. (3) Generally, the central angle of the arc-changing mechanism after the arc-changing mechanism does not exceed 150 degrees. If the central angle exceeds 150 degrees, there will be two difficulties. One difficulty is the limitation of the arc-changing mechanism structure. The other difficulty is that the excessively large central angle will cause the center of gravity of the arc-changing mechanism to shift. Especially when it exceeds 180 degrees, the two ends of the arc-changing mechanism will buckle inward after being pulled into place. This will cause the arc-changing mechanism to be unable to flatten after the glass is formed, thus making it impossible to produce the glass sheet or to perform subsequent glass bending. This seriously affects the continuity of glass bending. On this basis, the arc-changing mechanism of large-size bending tempering equipment is longer and the minimum radius that can be bent is relatively larger. Therefore, it is difficult to form small-size, small-radius bent tempered glass.

[0003] For the reasons mentioned above, large-size bending and tempering equipment in glass manufacturing enterprises has a high idle rate, resulting in significant waste and increasing the burden on enterprises. Therefore, it is necessary to develop a new glass bending and forming equipment that can handle both large and small sizes and radii of glass. Utility Model Content

[0004] The purpose of this invention is to provide a glass bending forming device that adjusts the length of the lower arc device according to the size of the glass to adapt to the processing and forming of glass of different sizes, improves the utilization rate of large-size tempered glass bending equipment, and at the same time ensures the forming accuracy of the glass and ensures the smooth arc bending of the mechanism used for glass bending after adjustment.

[0005] The technical solution adopted by this utility model is: a glass bending forming equipment, including a frame and a lower arc changing device and a lower arc changing horizontal moving device located on the frame; In the glass conveying direction, the lower arc changing device can be divided into a lower bending forming mechanism of appropriate process length and at least one lower forming candidate mechanism. The lower bending forming mechanism is used for bending and forming the glass. There is at least one set of lower arc-changing horizontal moving device, used to connect to the lower forming candidate mechanism; Each set of lower arc horizontal moving device includes at least one connecting mechanism and at least one moving mechanism, with the connecting mechanism connected between the corresponding lower forming candidate mechanism and the moving mechanism; The moving mechanism is used to drive the lower forming candidate mechanism to move horizontally relative to the lower bending forming mechanism, so that the lower forming candidate mechanism moves away from the bending range of the lower bending forming mechanism, or moves the lower forming candidate mechanism closer to a position where it can be connected to the lower bending forming mechanism.

[0006] As a preferred embodiment, the lower arc-changing device includes two opposing lower arc-changing mechanisms and multiple lower rollers spaced apart along the glass conveying direction, with both ends of the lower rollers connected to the lower arc-changing mechanism on the same side.

[0007] As a preferred embodiment, the lower arc-changing horizontal moving device is positioned on both outer sides of the corresponding lower forming candidate mechanism in the width direction or on one outer side along the glass conveying direction. Its advantages are: it provides two preferred arrangement structures for the horizontal moving device, resulting in a more rational design.

[0008] As a preferred embodiment, the connecting mechanism is connected to the lower arc-changing mechanisms on both sides of the lower forming candidate mechanism. The advantage of this design is that, since the main weight and frictional force during movement in the lower forming candidate mechanism come from the two lower arc-changing mechanisms on both sides of the glass conveying direction, placing the connection between the connecting mechanism and the lower forming candidate mechanism on both sides allows for a more uniform force distribution, smoother movement, reduced stress on individual components, prevention of excessive damage to individual components, and extended service life.

[0009] As a preferred embodiment, the connecting mechanism is connected to both ends of the lower roller of the lower forming candidate mechanism.

[0010] As a preferred embodiment, the lower arc-changing mechanism includes multiple rotatably connected lower arc-changing units, with at least two adjacent lower arc-changing units that can be connected or disconnected to realize the connection or separation of the lower arc-changing device in the glass conveying direction.

[0011] As a preferred embodiment, the connecting mechanism and the lower forming candidate mechanism are detachably connected.

[0012] As a preferred embodiment, the moving mechanism includes a linear guide, a slide, a moving component, and a moving drive component. The length direction of the linear guide is aligned with the glass conveying direction. The slide is slidably engaged with the linear guide, and a connecting mechanism is mounted on the slide. The moving component connects the moving drive component and the connecting mechanism, and the moving drive component drives the slide and the connecting mechanism to move horizontally. This design ensures that the moving direction of the lower forming support mechanism is parallel to the glass conveying direction, preventing movement jamming or uneven movement caused by directional deviation.

[0013] As a preferred embodiment, the connecting mechanism includes a connector and a connecting drive component. The connecting drive component is connected to the connector and is used to drive the connector to connect with or disconnect from the lower forming candidate mechanism. This design eliminates the need for direct human intervention, thus improving safety during processing.

[0014] As a preferred option, rolling elements are installed between the lower arc-changing mechanism and the frame. This design reduces friction during the movement of the lower forming candidate mechanism, preventing damage to the arc-changing mechanism's lifespan and resulting in smoother movement.

[0015] As a preferred embodiment, the lower end of the lower variable arc unit is provided with a rolling element.

[0016] As a preferred embodiment, there are two lower forming candidate mechanisms, with the lower bending forming mechanism positioned between them. The stroke range of each moving mechanism in the lower arc-changing horizontal moving device covers the horizontal movement range of both lower forming candidate mechanisms. This design allows for the horizontal movement of both lower forming candidate mechanisms to be completed using only one lower arc-changing horizontal moving device, thus improving the utilization rate of the device.

[0017] As a preferred embodiment, the lower forming candidate mechanism is a lower forming candidate conveying mechanism. The advantage of this design is that, as a preferred embodiment, the lower forming candidate conveying mechanism simultaneously serves two functions: conveying the glass and adjusting the process length of the lower bending forming mechanism.

[0018] As a preferred embodiment, the system also includes an upper moving system. The upper arc-changing device can be divided into an upper bending and forming mechanism of suitable process length and at least one upper forming candidate mechanism. The upper moving system is used to connect to and drive the upper forming candidate mechanism to move. The effect of this design is that the upper moving system allows the upper forming candidate mechanism to move without hindering the bending and forming of the glass.

[0019] Compared with the prior art, the beneficial effects of this utility model include at least the following: This glass bending forming equipment is equipped with a lower arc-changing horizontal moving device. When the lower arc-changing device is split into a lower bending forming mechanism and a lower forming candidate mechanism, only the lower bending forming mechanism participates in the bending forming of the target curved glass. The lower forming candidate mechanism is not used independently for glass bending forming, but rather for adjusting the process length of the lower bending forming mechanism. At this time, the lower arc-changing horizontal moving device can quickly connect to the lower forming candidate mechanism and drive it to move horizontally away from the lower bending forming mechanism, leaving sufficient arc-changing activity space for the lower bending forming mechanism. The purpose is not to hinder the arc-changing bending of the lower bending forming mechanism. This allows for the disassembly and assembly of the arc-changing system in existing large-size tempered glass bending equipment, enabling the bending forming and sheet output of smaller-size glass, thereby improving the utilization rate of large-size tempered glass bending equipment and reducing the production costs of glass manufacturers. Furthermore, the horizontal movement of the lower forming candidate mechanism, driven by the lower arc-changing horizontal moving device, ensures the smooth arc-changing bending of the lower bending forming mechanism. In addition, the lower forming candidate mechanism can be directly used for conveying glass before and / or after bending forming, improving glass production efficiency. Attached Figure Description

[0023] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," etc., used in the specification and claims of this utility model patent application do not express a quantity limitation, but rather indicate the presence of at least one; the terms "first," "second," and "third," as used herein, should not be considered as a limitation on the order of components, but are merely for distinguishing different components; the terms "comprising" or "including," etc., indicate that the elements or objects preceding "comprising" or "including" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0025] To more clearly describe the specific structural components of this glass bending forming equipment, in conjunction with the attached... Figure 1-7 The following embodiments are described: Example 1 See Figure 1A glass bending forming device includes a frame 1 and an upper arc-changing device, a lower arc-changing device 2, and a lower arc-changing horizontal moving device 3 located on the frame 1. The upper and lower arc-changing devices cooperate vertically to perform glass bending forming. In the glass conveying direction, the lower arc-changing device 2 can be divided into a lower bending forming mechanism 201 of a suitable process length and a lower forming candidate mechanism 202. The lower bending forming mechanism 201 is used for glass bending forming. The lower forming candidate mechanism 202 is equipped with a set of lower arc-changing horizontal moving device 3. The lower arc-changing horizontal moving device 3 includes a connecting mechanism 301 and a moving mechanism 302. The arc-shaped horizontal moving device 3 is located on the outer side of one end of the lower forming candidate mechanism 202 in the glass conveying direction; the connecting mechanism 301 is connected between the corresponding lower forming candidate mechanism 202 and the moving mechanism 302; the moving mechanism 302 is used to drive the lower forming candidate mechanism 202 to move horizontally relative to the lower bending forming mechanism 201, so that the lower forming candidate mechanism 202 moves away from the bending range of the lower bending forming mechanism 201; or the moving mechanism 302 moves the lower forming candidate mechanism 202 closer to a position where it can connect with the lower bending forming mechanism 201, facilitating the connection and merging of the lower forming candidate mechanism 202 and the lower bending forming mechanism 201. The appropriate process length refers to the length that is adapted to the target radius and target arc length of glass forming.

[0026] The lower arc-changing device 2 includes two opposing lower arc-changing mechanisms 203 and multiple lower rollers spaced apart along the glass conveying direction. The two ends of each lower roller are connected to a lower arc-changing mechanism 203 on the same side. Each lower arc-changing mechanism 203 includes multiple rotatably connected lower arc-changing units. At least two adjacent lower arc-changing units can be connected or disconnected to allow the lower arc-changing device 2 to be merged or split in the glass conveying direction. The connecting mechanism 301 is connected to both ends of the lower rollers of the lower forming candidate mechanism 202. In this example, two adjacent lower arc-changing units can be disconnected or connected, thus allowing the lower arc-changing device 2 to be split into a lower bending forming mechanism 201 of suitable process length and a lower forming candidate mechanism 202. In other embodiments, the lower arc-changing mechanism 203 has 2, 4, or 8 groups of detachable or connectable adjacent lower arc-changing units, distributed at different positions within the mechanism. Each group has 2 detachable or connectable lower arc-changing units. The appropriate position can be selected for splitting based on the target arc length and radius of the glass to be processed, making the splitting of the lower arc-changing mechanism more flexible and applicable to a wider range of situations. This allows the lower arc-changing device 2 to be split into a lower bending forming mechanism 201 of suitable process length and a lower forming candidate mechanism 202. Furthermore, the lower arc-changing mechanism 203 is deformable; adjacent lower arc-changing units in each pair can be connected or disconnected, further enhancing the flexibility of the equipment.

[0027] During production, if the glass size of the current batch is small, the lower arc-changing device 2 is laid flat and split into a lower bending forming mechanism 201 and a lower forming candidate mechanism 202. Glass processing is performed solely through the lower bending forming mechanism 201, the length of which is adapted to the glass size. Before bending the glass, the lower arc-changing horizontal moving device 3 moves the lower forming candidate mechanism 202 horizontally away from the lower bending forming mechanism 201, without hindering its arc-changing bending, thus achieving the bending of smaller glass sizes. If the glass size of subsequent batches increases, both the lower bending forming mechanism 201 and the lower forming candidate mechanism 202 are laid flat. The lower arc-changing horizontal moving device 3 moves the lower forming candidate mechanism 202 horizontally closer to the lower bending forming mechanism 201, connecting adjacent lower arc-changing units between them. After the lower bending forming mechanism 201 and the lower forming candidate mechanism 202 are connected as a whole into a single lower arc changing device 2, the lower arc changing device 2 can also be disassembled from other positions according to the size of the current batch of glass, so that the size of the disassembled lower bending forming mechanism 201 just meets the requirements.

[0028] It should be noted that the lower arc changing device exists regardless of whether it is split or not. When it is not split, the lower arc changing device is not connected to the lower arc changing device. When the lower forming candidate mechanism is split off, the lower arc changing device is connected to the lower arc changing device.

[0029] In this curved glass forming equipment, the lower arc-changing device 2 is split into a lower bending forming mechanism 201 and a lower forming candidate mechanism 202. Only the lower bending forming mechanism 201 participates in the bending forming of the target curved glass. The lower forming candidate mechanism 202 is not used alone for glass bending forming, but for adjusting the process length of the lower bending forming mechanism, such as lengthening the lower bending forming mechanism 201, or receiving the part removed after the length of the lower bending forming mechanism 201 is reduced. After the lower arc-changing device 2 is split into the lower bending forming mechanism 201 and the lower forming candidate mechanism 202, the two ends of the lower bending forming mechanism 201 are respectively connected to the arc-lifting mechanism. The movement of the arc-lifting mechanism drives the lower bending forming mechanism 201 to bend, thereby realizing the bending forming of the glass. At this time, the lower bending forming mechanism 201 and the lower forming candidate mechanism 202 are still in a close contact state. The lower forming candidate mechanism 202 hinders the arc-changing forming of the lower bending forming mechanism 201. To solve this problem, the bending forming equipment is also equipped with a lower arc-changing horizontal moving device 3. At this time, the lower arc-changing horizontal moving device 3 can... The lower forming candidate mechanism 202 is quickly connected and moved horizontally to move away from the lower bending forming mechanism 201, providing sufficient space for the lower bending forming mechanism 201 to change its arc. This ensures that the arc-changing bending of the lower bending forming mechanism 201 is not hindered. This allows for the disassembly and reassembly of the arc-changing system in existing large-size tempered glass bending equipment, enabling the bending and sheeting of smaller glass sizes. This improves the utilization rate of large-size tempered glass bending equipment, reduces production costs for glass manufacturers, and ensures smooth arc-changing bending of the lower bending forming mechanism by driving the horizontal movement of the lower forming candidate mechanism. Furthermore, the lower forming candidate mechanism can be directly used for conveying glass before and / or after bending forming, improving glass production efficiency.

[0030] The lower forming candidate mechanism 202 can also be used for conveying glass before and / or after forming. For example, after the glass is bent, it can pass directly through the lower forming candidate mechanism 202 to be conveyed as a sheet. This setup is more efficient and is of great significance for production continuity and ensuring production efficiency. The lower forming candidate mechanism 202 can also be used partly for adjusting the length of the lower bending forming mechanism 201 and partly for conveying glass before and / or after forming.

[0031] Example 2 See Figure 2 and Figure 3Unlike Embodiment 1, the lower arc-changing horizontal moving device 3 is a set, comprising two connecting mechanisms 301 and two moving mechanisms 302. The two connecting mechanisms 301 and two moving mechanisms 302 are respectively positioned on the two outer sides of the lower forming candidate mechanism 202 in the width direction (the width direction of the forming candidate mechanism 202 is perpendicular to the glass conveying direction). The connecting mechanism 301 is connected to the lower arc-changing mechanism 203 on the same side; thus, the two connecting mechanisms 301 and two moving mechanisms 302 work together to move the lower forming candidate mechanism 202. This design layout, by positioning the two connecting mechanisms 301 and two moving mechanisms 302 on the two outer sides of the lower forming candidate mechanism 202 in the width direction, does not affect the connection layout of the curved glass forming equipment and the lower segment or other equipment connected to it, and is convenient to use.

[0032] In this embodiment, refer to Figure 4 The connecting mechanism 301 includes a connector 3011 and a connecting drive 3012. The connecting drive 3012 is connected to the connector 3011 and is used to drive the connector 3011 to connect or disconnect from the lower forming candidate mechanism 202. For example, a slot can be provided at the end of the connector 3011, and a protrusion can be provided on the lower arc-changing mechanism 203 of the lower forming candidate mechanism 202. The connecting drive 3012 drives the end of the connector 3011 with the slot to approach or move away from the protrusion of the lower arc-changing mechanism 203 by electric, hydraulic or other means. After the slot and the protrusion are engaged, the connector 3011 is driven to connect with the lower forming candidate mechanism 202. After the slot and the protrusion are separated, the connector 3011 is driven to disconnect from the lower forming candidate mechanism 202. The above structure can realize the rapid connection and disconnection of the connecting mechanism 301 and the lower arc-changing mechanism 203.

[0033] In this embodiment, the moving mechanism 302 includes a linear guide 3021, a slide 3022, a moving member 3023, and a moving drive 3024. The length direction of the linear guide 3021 is consistent with the glass conveying direction. The slide 3022 is slidably engaged with the linear guide 3021, and the connecting mechanism 301 is disposed on the slide 3022. The moving member 3023 is connected between the moving drive 3024 and the connecting mechanism 301. The moving drive 3024 is used to drive the slide 3022 and the connecting mechanism 301 to move horizontally. After the connecting mechanism 301 is quickly connected to the lower arc-changing mechanism 203, the moving mechanism 302 can drive the translation of the lower forming candidate mechanism 202, thereby providing sufficient arc-changing activity space for the lower bending forming mechanism 201.

[0034] For example, the moving drive component 3024 is a drive motor, the moving component 3023 is a lead screw, and the slide 3022 is provided with a threaded part that engages with the lead screw thread. The drive motor drives the lead screw to rotate, so that the slide 3022 connected to the lead screw is linearly displaced along the linear guide component 3021.

[0035] Since the main weight and friction during movement in the lower forming candidate mechanism come from the two lower arc-changing mechanisms on both sides of the glass conveying direction, setting the connection position between the connecting mechanism and the lower forming candidate mechanism on both sides can make the force distribution more uniform, the movement process more stable, reduce the force on individual parts, avoid excessive damage to individual parts, and extend the service life.

[0036] Example 3 See Figure 5 Unlike Embodiment 1, the lower arc-changing horizontal moving device 3 is a set, comprising two connecting mechanisms 301 and two moving mechanisms 302. The lower arc-changing horizontal moving device 3 is positioned on the outer side of one end of the lower forming candidate mechanism 202 along the glass conveying direction. The two moving mechanisms 302 are respectively connected to both ends of the lower roller via the two connecting mechanisms 301. The design of the two moving mechanisms 302 facilitates calibration and improves the flatness of the movement of the lower forming candidate mechanism 202. This design layout also allows for rapid connection of the lower forming candidate mechanism and its horizontal movement to move it away from the lower bending forming mechanism, providing sufficient arc-changing activity space for the lower bending forming mechanism.

[0037] Example 4 See Figure 6 Unlike Embodiment 1, this embodiment has two lower forming candidate mechanisms 202 and two sets of lower arc-changing horizontal moving devices 3. The lower bending forming mechanism 201 is located between the two lower forming candidate mechanisms 202. Each set of lower arc-changing horizontal moving devices 3 includes two connecting mechanisms 301 and two moving mechanisms 302. The two connecting mechanisms 301 and two moving mechanisms 302 of each set of lower arc-changing horizontal moving devices 3 are respectively located on the two outer sides of the width direction of one lower forming candidate mechanism 202. The two connecting mechanisms 301 and two moving mechanisms 302 work together to drive the lower forming candidate mechanism 202 to move horizontally. The two sets of lower arc-changing horizontal moving devices 3 can respectively move the lower forming candidate mechanism 202 connected to them away from the lower bending forming mechanism 201, thereby leaving sufficient arc-changing activity space for the lower bending forming mechanism 201 and ensuring that the lower bending forming mechanism 201 can smoothly change arc and bend.

[0038] Example 5 See Figure 7Unlike Embodiment 4, the lower arc horizontal moving device 3 is a set, which includes two connecting mechanisms 301 and two moving mechanisms 302. The travel range of the two moving mechanisms 302 covers the horizontal movement range of the two lower forming candidate mechanisms 202. At the same time, the connecting mechanism 301 is detachably connected to the lower forming candidate mechanism 202. In this arrangement, one of the lower forming candidate mechanisms 202 is moved closer to or away from the lower bending forming mechanism 201 by the connecting mechanisms 301 on both sides, and then disconnected and connected to the other lower forming candidate mechanism 202, and then moved closer to or away from the lower bending forming mechanism 201. Compared with Embodiment 4, one set of lower arc horizontal moving device 3 is saved, and the utilization rate of a single set of lower arc horizontal moving device 3 is improved.

[0039] Example 6 See Figure 2 Furthermore, in the above embodiment, a rolling element 4 is provided between the lower arc-changing mechanism 203 and the frame 1. The rolling element can reduce the friction during the movement of the lower forming candidate mechanism 202, avoid damage to the life of the arc-changing mechanism, and make the movement more stable. Since the lower arc-changing mechanism 203 and the lower arc-changing device 2 as a whole need to bend and change arc, a rolling element 4 can be provided at the lower end of each lower arc-changing unit to facilitate better support by the rolling element.

[0040] Optionally, the rolling element may be a bearing, which is connected to the lower arc-changing unit by a fixing rod or bolts.

[0041] Example 7 Furthermore, in the above embodiments, the lower bending forming mechanism 201 is provided with a glass conveying mechanism on at least one side of the glass conveying direction for conveying the glass before and after bending forming. Preferably, the lower forming candidate mechanism 202 can be directly used as the lower forming candidate conveying mechanism, eliminating the need for additional conveying equipment, saving space, facilitating operation, and thus improving glass production efficiency. That is, the lower forming candidate conveying mechanism plays two roles simultaneously: one is for adjusting the process length of the lower bending forming mechanism, and the other is for conveying the glass before and / or after bending forming. More preferably, the lower bending forming mechanism is located at the front end of the lower forming candidate conveying mechanism in the glass conveying direction. The lower bending forming mechanism is used for bending the hot glass, and the lower forming candidate conveying mechanism is used for conveying the glass after bending forming. The time required for the glass to come out of the heating furnace and start bending forming is reduced, and the temperature drop of the glass is smaller, which is beneficial to the glass bending forming.

[0042] Example 8 Based on the above embodiments, an upper moving system is also included. The upper moving system is used to connect to and drive the upper forming candidate mechanism to move. Preferably, it is used to drive the upper forming candidate mechanism to move longitudinally and vertically, so that the upper forming candidate mechanism moves away from the bending range of the upper bending forming mechanism, thereby not hindering the upper bending forming mechanism from bending into an arc; or to bring the upper forming candidate mechanism closer to a position where it can connect with the upper bending forming mechanism, further allowing the upper forming candidate mechanism to connect and merge with the upper bending forming mechanism.

[0043] Preferably, the upper moving system includes a translation mechanism and a lifting mechanism. The lifting mechanism is mounted on the translation mechanism. The translation mechanism can drive the lifting mechanism to translate. The lifting mechanism can connect to and drive the upper forming candidate mechanism to lift, thereby moving the upper forming candidate mechanism away from the upper bending forming mechanism.

[0044] It should be noted that although the present invention has been described through the above embodiments, there may be other various embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but all such changes and modifications should fall within the scope of protection of the appended claims and their equivalents.
