Description

Technical Field

[0001] This utility model belongs to the field of glass forming technology, specifically relating to an adjustable arc-changing device and curved glass forming equipment. Background Technology

[0002] Currently, in the field of curved glass forming technology, the radius of curvature of curved glass is constrained by the arc length of the arc-changing mechanism of the curved glass production equipment due to various objective factors and production processes. For example, the radius of curvature performance index achieved by conventional large arc length curved glass forming equipment is limited by the central arc angle of the equipment being less than 180 degrees. For curved glass forming equipment with an arc length L, the minimum value of the radius of curvature R is R≥λ•L / π (λ is the safety factor, L is the arc length, the conventional value of λ is 0.75-0.9, and π is pi, with a value of 3.14). If glass with a radius of curvature R < λ•L / π is produced, the conventional approach is to purchase a new curved glass forming machine with a smaller arc length L, which increases production costs and investment in space, personnel, and other aspects.

[0055] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0056] Example 1

[0057] See Figure 1 as well as Figure 9This utility model discloses an adjustable arc-changing device, comprising: an upper arc-changing mechanism 10, which includes an upper constraint member 101 and a plurality of first upper connecting members 102, wherein the plurality of first upper connecting members 102 are arranged sequentially along the glass conveying direction, and the first ends of two adjacent first upper connecting members 102 are rotatably connected, and the second ends of at least two consecutive first upper connecting members 102 located at the beginning end and / or the end end are detachably connected to the upper constraint member 101; an upper fixed-length region is formed between the first upper connecting members 102 detachably connected to the upper constraint member 101, and an upper arc-changing region is formed between the remaining first upper connecting members 102 not connected to the upper constraint member 101; and a lower arc-changing mechanism 20, which includes a lower constraint member 201 and a plurality of first upper connecting members 102. A first lower connector 202 is arranged sequentially along the glass conveying direction. The first ends of two adjacent first lower connectors 202 are rotatably connected. A lower constraint 201 is detachably connected between the second ends of at least two consecutive first lower connectors 202 located at the beginning end and / or the end end. A lower fixed length region is formed between the first lower connectors 202 detachably connected to the lower constraint 201, and a lower arc changing region is formed between the remaining first lower connectors 202 not connected to the lower constraint 201. A drive mechanism 30 is included, which includes an upper drive structure 301 and a lower drive structure 302. The upper drive structure 301 drives the upper arc changing mechanism 10 to move to change the arc, and the lower drive structure 302 drives the lower arc changing mechanism 20 to move to change the arc.

[0058] The adjustable arc-changing device of this utility model can use an upper constraint member 101 to constrain at least two consecutive first upper connectors 102 located at the beginning and / or the end to obtain an upper fixed length region of the target length. The first upper connectors 102 constrained by the upper constraint member 101 in the upper fixed length region do not participate in the arc changing. And can use a lower constraint member 201 to constrain at least two consecutive first lower connectors 202 located at the beginning and / or the end to obtain a lower fixed length region of the target length. The first lower connectors 202 constrained by the lower constraint member 201 in the lower fixed length region do not participate in the arc changing. The first upper connectors 102 in the upper arc changing region and the first lower connectors 202 in the lower arc changing region participate in the arc changing, thereby obtaining the upper arc changing region and the lower arc changing region of the target length.

[0059] It should be noted that the upper fixed length zone and the upper variable arc zone of the target length both refer to the length when the upper variable arc mechanism 10 is in the flattened state, and the lower fixed length zone and the lower variable arc zone of the target length both refer to the length when the lower variable arc mechanism 20 is in the flattened state.

[0060] It should be noted that in the upper arc-changing mechanism 10, the upper constraint member 101 can be used to constrain at least two consecutive first upper connecting members 102 located at the first end so that they do not participate in the arc-changing, thereby obtaining the first upper fixed length region; the upper constraint member 101 can be used to constrain at least two consecutive first upper connecting members 102 located at the end so that they do not participate in the arc-changing, thereby obtaining the second upper fixed length region.

[0061] Similarly, in the lower arc-changing mechanism 20, the lower constraint member 201 can be used to constrain at least two consecutive first lower connecting members 202 located at the first end so that they do not participate in the arc-changing, thereby obtaining the first lower fixed length region; the lower constraint member 201 can be used to constrain at least two consecutive first lower connecting members 202 located at the end so that they do not participate in the arc-changing, thereby obtaining the second lower fixed length region.

[0062] See Figure 1 Both the upper arc-changing mechanism 10 and the lower arc-changing mechanism 20 are in a flattened state. The length of the first upper fixed-length zone is N1, and the length of the second upper fixed-length zone is N2. The lengths of the first and second upper fixed-length zones can be equal or unequal. The length of the first lower fixed-length zone is M1, and the length of the second lower fixed-length zone is M2. The lengths of the first and second lower fixed-length zones can be equal or unequal. Furthermore, the length of the first upper fixed-length zone needs to be compatible with the length of the first lower fixed-length zone, and the length of the second upper fixed-length zone needs to be compatible with the length of the second lower fixed-length zone. The length of the upper arc-changing zone is N3, and the length of the lower arc-changing zone is M3.

[0063] It should be noted that the curved glass forming equipment can be equipped with only one upper fixed length zone and one lower fixed length zone, or it can be equipped with two upper fixed length zones and two lower fixed length zones.

[0064] Therefore, by installing or removing the upper constraint member 101 to adjust the length of the upper fixed length zone, the more first upper connecting members 102 constrained by the upper constraint member 101, the larger the length of the upper fixed length zone. Since the total length of the upper arc-changing mechanism 10 is constant, the length of the upper arc-changing zone is smaller. Similarly, by installing or removing the lower constraint member 201 to adjust the length of the lower fixed length zone, the more first lower connecting members 202 constrained by the lower constraint member 201, the larger the length of the lower fixed length zone. Since the total length of the upper arc-changing mechanism 10 is constant, the length of the lower arc-changing zone is smaller.

[0065] Since the distance N0 between the two rotation centers on the first upper connecting member 102 remains unchanged when the upper arc-changing mechanism 10 is in a flattened or arc-changing state, see [reference]. Figure 5 When the lower arc-changing mechanism 20 is in a flattened or arc-changing state, the distance M0 between the two rotation centers on the first lower connector 202 remains unchanged. (See reference...) Figure 8Therefore, when both the upper arc-changing mechanism 10 and the lower arc-changing mechanism 20 are in the arc-changing state, the arc length L of the upper arc-changing region is N3, and the arc length of the lower arc-changing region is M3. Thus, the smaller the length of the upper arc-changing region in the flattened state, that is, the smaller the arc length of the upper arc-changing region in the arc-changing state, and the smaller the length of the lower arc-changing region in the flattened state, that is, the smaller the arc length of the lower arc-changing region in the arc-changing state, according to the curvature radius R≥λ•L / π, since the curvature radius R is positively correlated with the arc length L, the smaller the corresponding curvature radius R that can be achieved.

[0066] After determining the length of the upper variable arc region in the flattened state, that is, after determining the arc length of the upper variable arc region in the variable arc state, the upper variable arc region with the target radius of curvature can be obtained by controlling the arc center angle of the upper variable arc region using the upper drive structure 301; after determining the length of the upper variable arc region in the flattened state, that is, after determining the arc length of the lower variable arc region in the variable arc state, the lower variable arc region with the target radius of curvature can be obtained by controlling the arc center angle of the lower variable arc region using the lower drive structure 302.

[0067] When the upper drive structure 301 drives the upper arc-changing mechanism 10 to move, all the first upper connectors 102 in the upper fixed length area only transmit the driving force of the upper drive structure 301, but do not participate in the arc changing. The first upper connectors 102 in the upper arc-changing area can achieve arc changing through relative rotation.

[0068] Similarly, when the current driving structure 302 drives the upper arc-changing mechanism 10 to move, all the first lower connecting parts 202 in the lower fixed length area only transmit the driving force of the upper driving structure 301, but do not participate in the arc changing. The first lower connecting parts 202 in the lower arc-changing area can achieve arc changing through relative rotation.

[0069] In this embodiment of the utility model, the upper constraint member 101 is a rigid structure, or the upper constraint member 101 and the corresponding first upper connecting member 102 are detachably connected to form a rigid structure; the lower constraint member 201 is a rigid structure, or the lower constraint member 201 and the corresponding first lower connecting member 202 are detachably connected to form a rigid structure.

[0070] It should be noted that the upper constraint member 101 itself is a rigid plate, such as a metal plate, so that the upper constraint member 101 is rigidly connected to the corresponding first upper connector 102; of course, the upper constraint member 101 can also be a flexible structure, such as the upper constraint member 101 being a metal rope, in which case the upper constraint member 101 and the corresponding first upper connector 102 can be detachably connected to form a rigid structure.

[0071] Similarly, the lower constraint member 201 itself is a rigid plate, such as a metal plate, so that the lower constraint member 201 is rigidly connected to the corresponding first lower connector 202; of course, the lower constraint member 201 can also be a flexible structure, such as a metal rope, in which case the lower constraint member 201 and the corresponding first lower connector 202 can be detachably connected to form a rigid structure.

[0072] In this embodiment of the present invention, the upper drive structure 301 includes a first upper drive motor 3011, a second upper drive motor 3012, a first upper traction member 3013, and a second upper traction member 3014; the first end of the first upper traction member 3013 is connected to the first upper connecting member 102 located at the first position, and the second end of the first upper traction member 3013 is connected to the output shaft of the first upper drive motor 3011; the first end of the second upper traction member 3014 is connected to the first upper connecting member 102 located at the last position, and the second end of the second upper traction member 3014 is connected to the output shaft of the second upper drive motor 3012.

[0073] See Figure 1 as well as Figure 2 When the adjustable arc-changing device performs arc changing, the first upper drive motor 3011 rotates clockwise to tighten the first upper traction member 3013, thereby driving the first upper fixed length zone to move upward as a whole, and then driving the end of the upper arc-changing zone connected to the first upper fixed length zone to rotate upward clockwise; the second upper drive motor 3012 rotates counterclockwise to tighten the second upper traction member 3014, thereby driving the second upper fixed length zone to move upward as a whole, and then driving the end of the upper arc-changing zone connected to the second upper fixed length zone to rotate upward counterclockwise, so as to realize the arc changing of the upper arc-changing zone.

[0074] Specifically, the first upper traction member 3013 is a metal rope, such as a steel wire rope or iron wire rope. The first end of the first upper traction member 3013 is tied to the first upper connector 102 located in the first position, and the second end of the first upper traction member 3013 is tied to the output shaft of the first upper drive motor 3011.

[0075] In this embodiment of the present invention, the lower drive structure 302 includes a first lower drive motor 3021, a second lower drive motor 3022, a first lower traction member 3023, and a second lower traction member 3024; the first end of the first lower traction member 3023 is connected to the first lower connecting member 202 located at the first position, and the second end of the first lower traction member 3023 is connected to the output shaft of the first lower drive motor 3021; ​​the first end of the second lower traction member 3024 is connected to the first lower connecting member 202 located at the last position, and the second end of the second lower traction member 3024 is connected to the output shaft of the second lower drive motor 3022.

[0076] See Figure 1 as well as Figure 2When the adjustable arc-changing device performs arc changing, the first lower drive motor 3021 rotates clockwise to tighten the first lower traction member 3023, thereby driving the first lower fixed length area to move upward as a whole, and then driving the end of the lower arc-changing area connected to the first lower upper fixed length area to rotate upward clockwise; the second lower drive motor 3022 rotates counterclockwise to tighten the second lower traction member 3024, thereby driving the second lower upper fixed length area to move upward as a whole, and then driving the end of the lower arc-changing area connected to the second lower fixed length area to rotate upward counterclockwise, so as to realize the arc changing of the lower arc-changing area.

[0077] Specifically, the first lower traction member 3023 is a metal rope, such as a steel wire rope or iron wire rope. The first end of the first lower traction member 3023 is tied to the first lower connector 202 located in the first position, and the second end of the first lower traction member 3023 is tied to the output shaft of the first lower drive motor 3021.

[0078] In this embodiment of the utility model, the upper arc mechanism 10 includes a plurality of first upper rotating shafts 103, and the first end of the first upper connector 102 is provided with a first upper connecting hole 104. The first upper rotating shaft 103 passes through the first upper connecting hole 104 of two adjacent first upper connectors 102 so that the two adjacent first upper connectors 102 are rotatably connected through the first upper rotating shaft 103.

[0079] For example, see Figures 3 to 5 The first upper connecting member 102 is a T-shaped plate; within the upper fixed length region, due to the constraint of the upper constraint member 101, two adjacent first upper connecting members 102 are rigidly connected and do not rotate relative to each other; while within the upper variable arc region, two adjacent first upper connecting members 102 can rotate relative to each other; and the upper fixed length region and the upper variable arc region are rotatably connected, so that under the drive of the upper drive structure 301, the upper variable arc region of the upper variable arc mechanism 10 achieves arc change.

[0080] In this embodiment of the present invention, the upper arc-changing mechanism 10 includes a plurality of second upper connecting members 105. In the upper arc-changing region, at least one second upper connecting member 105 is detachably connected between two adjacent first upper connecting members 102. The second end of the first upper connecting member 102 is provided with a second upper rotating shaft 106 and an upper sliding groove 107. The first end of the second upper connecting member 105 is provided with a second upper connecting hole 108. The second end of the second upper connecting member 105 is provided with a third upper rotating shaft 109. The second upper connecting hole 108 of the second upper connecting member 105 is sleeved on the second upper rotating shaft 106 of one of the first upper connecting members 102 to achieve a rotatable connection. The third upper rotating shaft 109 of the second upper connecting member 105 is inserted into the upper sliding groove 107 on another first upper connecting member 102 to achieve a rotatable connection and a sliding connection.

[0081] Continue reading Figure 4 as well as Figure 5Multiple second upper connectors 105 are arranged in a cross configuration to form a scissor-type four-bar linkage. The second upper connectors 105 can assist the first upper connectors 102 in the arc-changing zone to rotate more stably relative to each other, thereby further improving the stability and accuracy of the arc-changing mechanism.

[0082] Specifically, when the arc is changed in the upper arc changing area, the third upper rotating shaft 109 can rotate within the upper sliding groove 107, and the third upper rotating shaft 109 can slide along the upper sliding groove 107.

[0083] Since the first upper connector 102 in the upper fixed length zone does not rotate relative to each other, and the upper fixed length zone and the upper variable arc zone are rotatably connected, in order to obtain an upper variable arc zone with a shorter arc length, it is necessary to remove the second upper connector 105 in the target area. When removing it, the second upper connector 105 can be directly removed when the upper variable arc mechanism 10 is in a flattened state. At this time, the second upper connecting hole 108 of the second upper connector 105 is separated from the corresponding second upper rotating shaft 106, and the third upper rotating shaft 109 of the second upper connector 105 is separated from the corresponding upper sliding groove 107.

[0084] In this embodiment of the utility model, the lower arc mechanism 20 includes a plurality of roller tracks 203. The first end of the first lower connector 202 is provided with a first lower connecting hole 204. The roller tracks 203 pass through the first lower connecting holes 204 of two adjacent first lower connectors 202 so that two adjacent first lower connectors 202 are rotatably connected through the roller tracks 203.

[0085] For example, see Figure 7 as well as Figure 8 The first lower connecting member 202 is a T-shaped plate; within the lower fixed length region, due to the constraint of the lower constraint member 201, two adjacent first lower connecting members 202 are rigidly connected and do not rotate relative to each other; while within the lower variable arc region, two adjacent first lower connecting members 202 can rotate relative to each other; and the lower fixed length region and the lower variable arc region are rotatably connected, so that under the drive of the lower drive structure 302, the lower variable arc region of the lower variable arc mechanism 20 achieves arc change.

[0086] Glass is conveyed from the heating furnace to the adjustable arc-changing device, and the roller conveyor 203 rotates to convey the glass to the predetermined position of the lower arc-changing mechanism 20 for forming. When the glass is forming, the roller conveyor 203 stops rotating. After the glass is formed, the roller conveyor 203 rotates again to convey the formed glass to the next station. Thus, the roller conveyor 203 is rotatably connected to the two adjacent first lower connecting parts 202. Since how the roller conveyor 203 rotates to realize glass conveying and how to stop rotating is existing technology, it will not be described in detail here. For example, the existing belt pulley drive mechanism can be directly used to drive the roller conveyor 203 to rotate to convey the glass, or the existing sprocket drive mechanism can be directly used to drive the roller conveyor 203 to rotate to convey the glass.

[0087] In this embodiment of the present invention, the lower arc-changing mechanism 20 includes a plurality of second lower connecting members 205. In the lower arc-changing region, at least one second lower connecting member 205 is detachably connected between two adjacent first lower connecting members 202. The second end of the first lower connecting member 202 is provided with a first lower rotating shaft 206 and a lower sliding groove 207. The first end of the second lower connecting member 205 is provided with a second lower connecting hole 208, and the second end of the second lower connecting member 205 is provided with a second lower rotating shaft 209. The second lower connecting hole 208 of the second lower connecting member 205 is sleeved on the first lower rotating shaft 206 of one of the first lower connecting members 202 to achieve a rotatable connection, and the second lower rotating shaft 209 of the second lower connecting member 205 is inserted into the lower sliding groove 207 on another first lower connecting member 202 to achieve a rotatable connection and a sliding connection.

[0088] Continue reading Figures 3 to 5 Multiple second lower connectors 205 are arranged in a cross configuration to form a scissor-type four-bar linkage. The second lower connectors 205 can assist the first lower connectors 202 in the arc-changing zone to rotate more stably relative to each other, thereby further improving the stability and accuracy of the arc-changing mechanism.

[0089] Specifically, when the arc is changed in the lower arc region, the second lower rotating shaft 209 can rotate within the lower sliding groove 207, and the second lower rotating shaft 209 can slide along the lower sliding groove 207.

[0090] Since the first lower connector 202 in the lower fixed length zone does not rotate relative to each other, and the lower fixed length zone and the lower variable arc zone are rotatably connected, in order to obtain a lower variable arc zone with a shorter arc length, it is necessary to remove the second lower connector 205 in the target area. When removing it, the second lower connector 205 can be directly removed when the lower variable arc mechanism 20 is in the flattened state. At this time, the second lower connecting hole 208 of the second lower connector 205 is separated from the corresponding first lower rotating shaft 206, and the second lower rotating shaft 209 of the second lower connector 205 is separated from the corresponding lower sliding groove 207.

[0091] In this embodiment of the utility model, the adjustable arc-changing device further includes an upper fixed frame 40, an upper lifting frame 50, and a hanging plate 60; the upper drive structure 301 is disposed on the upper lifting frame 50, the first end of the hanging plate 60 is connected to the upper arc-changing mechanism 10, and the second end of the hanging plate 60 is connected to the upper lifting frame; the lower drive structure 302 is disposed on the upper fixed frame 40.

[0092] See Figure 1 as well as Figure 2 The upper drive structure 301 and the hanging plate 60 can move up and down with the upper lifting frame 50, so that the upper arc mechanism 10 can move up and down as a whole, which makes it easier for the roller conveyor 203 to transport the finished glass to the next station.

[0093] It should be noted that how the upper lifting frame 50 achieves vertical lifting is existing technology and will not be described in detail here. For example, the upper lifting frame 50 includes a frame body and a lifting cylinder. The lifting cylinder drives the frame body to lift vertically, thereby driving the upper drive structure 301 and the hanging plate 60 to lift vertically, and in turn driving the upper arc-changing mechanism 10 to lift vertically.

[0094] Example 2

[0095] See Figures 1 to 9 This utility model discloses a curved glass forming equipment, including the above-mentioned adjustable arc device.

[0096] The curved glass forming equipment of this invention adopts the above-mentioned adjustable arc device, thereby enabling the production of curved glass with a target radius of curvature.

[0097] The glass forming process is as follows:

[0098] 1. When both the upper arc-changing mechanism 10 and the lower arc-changing mechanism 20 are in a flattened state, the upper fixed length region of the target length is obtained by using the upper constraint member 101 and the lower fixed length region of the target length is obtained by using the lower constraint member 201, thereby obtaining the upper arc-changing region and the lower arc-changing region of the target length.

[0099] 2. The upper arc-changing mechanism 10 moves upward and separates from the lower arc-changing mechanism 20. The glass is transported from the heating furnace to the lower arc-changing mechanism 20 of the curved glass forming equipment. The roller conveyor 203 transports the glass to the predetermined position in the lower arc-changing area by rotating and then stops rotating.

[0100] 3. After determining the length of the upper variable arc region in the flattened state, that is, after determining the arc length of the upper variable arc region in the variable arc state, the upper variable arc region with the target radius of curvature can be obtained by controlling the arc center angle of the upper variable arc region using the upper drive structure 301; after determining the length of the upper variable arc region in the flattened state, that is, after determining the arc length of the lower variable arc region in the variable arc state, the lower variable arc region with the target radius of curvature can be obtained by controlling the arc center angle of the lower variable arc region using the lower drive structure 302.

[0101] 4. After the upper and lower arc-changing areas have completed the curvature radius adjustment, the upper arc-changing mechanism 10 moves downward to press the glass onto the lower arc-changing mechanism 20 for forming. After the glass is formed, a curved glass with the target curvature radius is obtained. The upper arc-changing mechanism 10 moves upward and separates from the lower arc-changing mechanism 20.

[0102] 5. The upper drive structure 301 drives the upper arc-changing mechanism 10 to a flattened state, and the lower drive structure 302 drives the lower arc-changing mechanism 20 to a flattened state. The roller conveyor 203 transports the formed curved glass with the target radius of curvature to the next station by rotating.

[0103] Since curved glass is formed by pressing in the upper and lower curved areas, the smaller the radius of curvature of the upper and lower curved areas, the smaller the radius of curvature of the formed curved glass; the larger the radius of curvature of the upper and lower curved areas, the larger the radius of curvature of the formed curved glass.

[0104] The technical means disclosed in this utility model are not limited to those disclosed in the following embodiments, but also include technical solutions composed of any combination of the following technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
