在现有技术中,玻璃板被夹持在上模具与下模具之间,通过加热上模具和下模具,将热量传递到玻璃板上以便实现玻璃板的预热。In the prior art, a glass plate is clamped between an upper mold and a lower mold, and heat is transferred to the glass plate by heating the upper mold and the lower mold in order to achieve preheating of the glass plate.
由于玻璃板2被放置在预热支架210上,因此可以直接对玻璃板2进行加热,从而可以使热量更有效地传递到玻璃板2上。因此,与通过加热上模具和下模具来预热玻璃板相比,通过利用预热装置20来预热玻璃板2,可以降低能耗,即预热装置20具有能耗低的优点。关于本申请无需利用上模具和下模具夹持玻璃板2的原因,将在下文进行详细地描述。Since the glass plate 2 is placed on the preheating bracket 210, the glass plate 2 can be directly heated, so that heat can be more effectively transferred to the glass plate 2. Therefore, compared with preheating the glass plate by heating the upper mold and the lower mold, the energy consumption can be reduced by using the preheating device 20 to preheat the glass plate 2, that is, the preheating device 20 has the advantage of low energy consumption. The reason why the present application does not need to hold the glass plate 2 by using the upper mold and the lower mold will be described in detail below.
如图1和图2所示,预热支架210可以包括多个预热支撑柱211,多个预热支撑柱211可以间隔开地设置。多个预热支撑柱211的上沿或上表面可以位于同一水平面上。As shown in FIG. 1 and FIG. 2, the preheating bracket 210 may include a plurality of preheating support columns 211, and the plurality of preheating support columns 211 may be disposed at intervals. The upper edges or the upper surfaces of the plurality of preheating support columns 211 may be located on the same horizontal plane.
上预热板230可上下移动地设置,例如可以通过气缸、电缸等驱动上预热板230上下移动。在将玻璃板2放置到预热支架210上或者从预热支架210上取走玻璃板2时,可以使上预热板230向上移动,以便便于搬运玻璃板2。在预热玻璃板2时,可以使上预热板230向下移动,以便加热玻璃板2。The upper preheating plate 230 is provided to be movable up and down. For example, the upper preheating plate 230 can be driven to move up and down by an air cylinder or an electric cylinder. When the glass plate 2 is placed on or removed from the preheating bracket 210, the upper preheating plate 230 may be moved upward to facilitate the handling of the glass plate 2. When the glass plate 2 is preheated, the upper preheating plate 230 may be moved downward to heat the glass plate 2.
上预热件240和下预热件250都可以是加热管60。如图12和图13所示,加热管60可以包括管体610、多个加热部620、第一引出部631和第二引出部632。第一引出部631可以与多个加热部620中的一个电连接,第二引出部632可以与多个加热部620中的另一个电连接。Both the upper preheating member 240 and the lower preheating member 250 may be heating pipes 60. As shown in FIGS. 12 and 13, the heating pipe 60 may include a pipe body 610, a plurality of heating portions 620, a first lead-out portion 631, and a second lead-out portion 632. The first lead-out portion 631 may be electrically connected to one of the plurality of heating portions 620, and the second lead-out portion 632 may be electrically connected to the other of the plurality of heating portions 620.
管体610可以具有管腔611,多个加热部620可以设在管腔611内,多个加热部620可以串联。多个加热部620中的至少两个的电阻可以彼此不相等和/或多个加热部620中的该至少两个的长度密度可以彼此不相等,多个加热部620中的该至少两个在管体610的长度方向上可以与管体610的不同部分相对。The tube body 610 may have a lumen 611, a plurality of heating portions 620 may be disposed in the lumen 611, and a plurality of heating portions 620 may be connected in series. The resistances of at least two of the plurality of heating portions 620 may be unequal to each other and / or the length densities of the at least two of the plurality of heating portions 620 may be unequal to each other. The length of the pipe body 610 may be opposite to different parts of the pipe body 610.
其中,一个加热部620的该长度密度是指:该加热部620的长度与管体610的与该加热部620相对的部分的长度的比值。如果加热部620是非直线状(例如波纹状、螺旋状),加热部620的长度是指:将加热部620拉直后,加热部620的实际长度。The length density of a heating portion 620 refers to a ratio of a length of the heating portion 620 to a length of a portion of the pipe body 610 opposite to the heating portion 620. If the heating portion 620 is non-linear (eg, corrugated or spiral), the length of the heating portion 620 refers to the actual length of the heating portion 620 after the heating portion 620 is straightened.
在利用热弯方法制造3D玻璃制品时,玻璃板的不同部分所需的热量也不同。具体地,需要弯曲的部分需要吸收更多的热量,不需要弯曲的部分可以吸收较少的热量。现有的加热管只能均匀地散发热量,即现有的加热管的不同部分散发的热量基本相等,这就导致玻璃板的不需要热弯的部分也被加热到最高温度(实际上不需要被加热到最高温度),因此存在热能浪费。When manufacturing 3D glass products using the hot bending method, different parts of the glass plate require different amounts of heat. Specifically, the part that needs to be bent needs to absorb more heat, and the part that does not need to be bent can absorb less heat. The existing heating pipe can only radiate heat uniformly, that is, the heat emitted from different parts of the existing heating pipe is basically equal, which results in that the part of the glass plate that does not need to be bent is also heated to the highest temperature (in fact, it does not need Is heated to the highest temperature), so there is a waste of thermal energy.
根据本发明实施例的加热管60通过使多个加热部620中的该至少两个的电阻彼此不相等和/或多个加热部620中的该至少两个的长度密度彼此不相等,从而可以使该至少两个加热部620产生的热量彼此不相等。The heating pipe 60 according to the embodiment of the present invention can make the resistances of the at least two of the plurality of heating portions 620 different from each other and / or the length densities of the at least two of the plurality of heating portions 620 different from each other, so that The heat generated by the at least two heating portions 620 is made different from each other.
由于多个加热部620中的该至少两个在管体610的长度方向上与管体610的不同部分相对,因此可以使加热管60的不同部分散发的热量彼此不相等。具体地,可以使加热管60的散发热量较多的部分与玻璃板2的需要热弯的部分相对,使加热管60的散发热量较少的部分与玻璃板2的不需要热弯的部分相对,以便降低加热管60的能耗。Since the at least two of the plurality of heating portions 620 are opposed to different portions of the tube body 610 in the length direction of the tube body 610, the heat radiated from different portions of the heating tube 60 can be made different from each other. Specifically, the portion of the heating tube 60 that emits more heat may be opposed to the portion of the glass plate 2 that needs to be bent, and the portion of the heating tube 60 that emits less heat may be opposed to the portion of the glass plate 2 that does not need to be bent In order to reduce the energy consumption of the heating pipe 60.
因此,根据本发明实施例的加热管60具有能耗低等优点。与现有的加热管相比,根据本发明实施例的加热管60可以降低5%-10%的能耗。Therefore, the heating pipe 60 according to the embodiment of the present invention has the advantages of low energy consumption and the like. Compared with the existing heating pipe, the heating pipe 60 according to the embodiment of the present invention can reduce energy consumption by 5% -10%.
根据本发明实施例的加热管60并不限于用于预热支架210。根据玻璃板2的实际热弯形状,可以将加热管60设计为两温区、三温区或四个以上的温区。可以根据模具的具体形状,对其散热保温能力进行计算,加热管60的与模具的散热较快的部分和玻璃板2的热弯部分相对的区域,可以作为高温区,加热管60的与模具的保温性能较好的部分相对的区域可以作为低温区。The heating pipe 60 according to the embodiment of the present invention is not limited to being used for preheating the bracket 210. According to the actual hot-bend shape of the glass plate 2, the heating tube 60 may be designed into two temperature zones, three temperature zones, or more than four temperature zones. According to the specific shape of the mold, its heat dissipation and heat insulation capacity can be calculated. The area of the heating tube 60 that is relatively fast to the mold and the heat-bent portion of the glass plate 2 can be used as the high temperature area. Relatively good heat insulation performance can be used as the low temperature area.
在本发明的一个示例中,多个加热部620可以包括主加热部和侧加热部,该主加热部的端部可以与该侧加热部的端部电连接,该侧加热部的电阻与该主加热部的电阻可以不相等和/或该侧加热部的长度密度与该主加热部的长度密度可以不相等。In one example of the present invention, the plurality of heating portions 620 may include a main heating portion and a side heating portion, and an end portion of the main heating portion may be electrically connected to an end portion of the side heating portion, and a resistance of the side heating portion and the The resistance of the main heating portion may be unequal and / or the length density of the side heating portion and the length density of the main heating portion may be unequal.
由此加热管60可以具有两个温区(一个高温区和一个低温区)。其中,加热管60的高温区(例如与该侧加热部相对的部分)可以与玻璃板2的需要热弯的部分相对,加热管60的低温区(例如与该主加热部相对的部分)可以与玻璃板2的不需要热弯的部分相对。该示例的加热管60适于加热具有一个热弯部分的玻璃板2。The heating tube 60 may thus have two temperature zones (a high temperature zone and a low temperature zone). Wherein, the high-temperature region of the heating tube 60 (for example, a portion opposite to the side heating portion) may be opposite to the portion of the glass plate 2 that needs to be bent, and the low-temperature region of the heating tube 60 (for example, a portion opposite to the main heating portion) may It is opposed to the part of the glass plate 2 which does not need to be bent. The heating pipe 60 of this example is suitable for heating the glass plate 2 having one bent portion.
如图12和图13所示,多个加热部620可以包括第一侧加热部621、第二侧加热部622和中间加热部623,中间加热部623的第一端可以与第一侧加热部621的端部电连接,中间加热部623的第二端可以与第二侧加热部622的端部电连接。As shown in FIGS. 12 and 13, the plurality of heating portions 620 may include a first side heating portion 621, a second side heating portion 622, and an intermediate heating portion 623. A first end of the intermediate heating portion 623 may be connected to the first side heating portion. An end of 621 is electrically connected, and a second end of the intermediate heating portion 623 may be electrically connected to an end of the second side heating portion 622.
其中,第一侧加热部621的电阻与中间加热部623的电阻可以不相等和/或第一侧加热部621的长度密度与中间加热部623的长度密度可以不相等,第二侧加热部622的电阻与中间加热部623的电阻可以不相等和/或第二侧加热部622的长度密度与中间加热部623的长度密度可以不相等。Among them, the resistance of the first-side heating portion 621 and the resistance of the intermediate heating portion 623 may be unequal and / or the length density of the first-side heating portion 621 and the length-density of the intermediate heating portion 623 may be unequal, and the second-side heating portion 622 The electrical resistance of the intermediate heating portion 623 may be different from the electrical resistance of the intermediate heating portion 623 and / or the length density of the second heating portion 622 may be different from the length density of the intermediate heating portion 623.
由此加热管60可以具有三个温区(例如两个高温区和一个低温区)。其中,加热管60的两个高温区(例如与第一侧加热部621和第二侧加热部622相对的部分)可以与玻璃板2的需要热弯的部分相对,加热管60的低温区(例如与中间加热部623相对的部分)可以与玻璃板2的不需要热弯的部分相对。The heating tube 60 may thus have three temperature zones (for example, two high temperature zones and one low temperature zone). Wherein, the two high-temperature regions of the heating tube 60 (for example, portions opposite to the first-side heating portion 621 and the second-side heating portion 622) may be opposite to the portions of the glass plate 2 that need to be bent, and the low-temperature regions of the heating tube 60 ( For example, a portion opposed to the intermediate heating portion 623 may be opposed to a portion of the glass plate 2 that does not need to be bent.
换言之,第一侧加热部621和第二侧加热部622可以与玻璃板2的需要热弯的部分相对,中间加热部623可以与玻璃板2的不需要热弯的部分相对。该示例的加热管60适于加热具有两个热弯部分的玻璃板2,例如玻璃板2的两个端部为其热弯部分。In other words, the first side heating portion 621 and the second side heating portion 622 may be opposed to a portion of the glass plate 2 that needs to be bent, and the intermediate heating portion 623 may be opposed to the portion of the glass plate 2 that does not need to be bent. The heating pipe 60 of this example is suitable for heating a glass plate 2 having two heat-bent portions, for example, both ends of the glass plate 2 are its heat-bent portions.
优选地,第一侧加热部621的电阻可以等于第二侧加热部622的电阻和/或第一侧加热部621的长度密度可以等于第二侧加热部622的长度密度。由此可以使玻璃板2的两个端部吸收的热量大体相等,从而可以使加热管60的结构更加合理。Preferably, the resistance of the first side heating portion 621 may be equal to the resistance of the second side heating portion 622 and / or the length density of the first side heating portion 621 may be equal to the length density of the second side heating portion 622. As a result, the heat absorbed by the two end portions of the glass plate 2 can be made substantially equal, and the structure of the heating tube 60 can be made more reasonable.
如图13所示,多个加热部620构成多个加热部组624,多个加热部组624可以沿第一方向间隔开地设置,该第一方向可以垂直于管体610的长度方向。在该第一方向上相邻的两个加热部组624可以串联。其中,管体610的长度方向如图13中的箭头B所示,该第一方向如图13中的箭头C所示。As shown in FIG. 13, the plurality of heating portions 620 constitute a plurality of heating portion groups 624. The plurality of heating portion groups 624 may be spaced apart along a first direction, and the first direction may be perpendicular to the length direction of the pipe body 610. Two heating unit groups 624 adjacent in the first direction may be connected in series. The length direction of the tube body 610 is shown by arrow B in FIG. 13, and the first direction is shown by arrow C in FIG. 13.
每个加热部组624可以包括第一侧加热部621、第二侧加热部622和中间加热部623,中间加热部623的第一端可以与第一侧加热部621的端部电连接,中间加热部623的第二端可以与第二侧加热部622的端部电连接。其中,第一侧加热部621的电阻与中间加热部623的电阻可以不相等和/或第一侧加热部621的长度密度与中间加热部623的长度密度可以不相等,第二侧加热部622的电阻与中间加热部623的电阻可以不相等和/或第二侧加热部622的长度密度与中间加热部623的长度密度可以不相等。Each heating section group 624 may include a first side heating section 621, a second side heating section 622, and an intermediate heating section 623. A first end of the intermediate heating section 623 may be electrically connected to an end of the first side heating section 621. The second end of the heating portion 623 may be electrically connected to the end of the second-side heating portion 622. Among them, the resistance of the first-side heating portion 621 and the resistance of the intermediate heating portion 623 may be unequal and / or the length density of the first-side heating portion 621 and the length-density of the intermediate heating portion 623 may be unequal, and the second-side heating portion 622 The electrical resistance of the intermediate heating portion 623 may be different from the electrical resistance of the intermediate heating portion 623 and / or the length density of the second heating portion 622 may be different from the length density of the intermediate heating portion 623.
由此可以进一步增加管体610的与第一侧加热部621相对的部分和管体610的与中间加热部623相对的部分的温差、进一步增加管体610的与第二侧加热部622相对的部分和管体610的与中间加热部623相对的部分的温差,从而可以进一步降低加热管60的能耗。This can further increase the temperature difference between the portion of the tube body 610 opposite to the first-side heating portion 621 and the portion of the tube body 610 opposite to the intermediate heating portion 623, and further increase the The temperature difference between the portion and the portion of the tube body 610 opposite to the intermediate heating portion 623 can further reduce the energy consumption of the heating tube 60.
多个加热部组624的第一侧加热部621的电阻可以彼此相等和/或多个加热部组624的第一侧加热部621的长度密度可以彼此相等,多个加热部组624的第二侧加热部622的电阻可以彼此相等和/或多个加热部组624的第二侧加热部622的长度密度可以彼此相等。由此可以使加热管60的结构更加合理。The resistances of the first side heating portions 621 of the plurality of heating portion groups 624 may be equal to each other and / or the length densities of the first side heating portions 621 of the plurality of heating portion groups 624 may be equal to each other. The resistances of the side heating portions 622 may be equal to each other and / or the length densities of the second side heating portions 622 of the plurality of heating portion groups 624 may be equal to each other. This can make the structure of the heating pipe 60 more reasonable.
优选地,第一侧加热部621的电阻可以等于第二侧加热部622的电阻和/或第一侧加热部621的长度密度可以等于第二侧加热部622的长度密度。由此可以使玻璃板2的两个端部吸收的热量大体相等,从而可以使加热管60的结构更加合理。Preferably, the resistance of the first side heating portion 621 may be equal to the resistance of the second side heating portion 622 and / or the length density of the first side heating portion 621 may be equal to the length density of the second side heating portion 622. As a result, the heat absorbed by the two end portions of the glass plate 2 can be made substantially equal, and the structure of the heating tube 60 can be made more reasonable.
如图12和图13所示,在本发明的一个具体示例中,每个加热部620可以构造成螺旋状,多个加热部620中的该至少两个的螺距和直径中的至少一者可以彼此不相等。由此可以使加热管60的结构更加合理。As shown in FIGS. 12 and 13, in a specific example of the present invention, each heating portion 620 may be configured in a spiral shape, and at least one of the pitch and diameter of the at least two of the plurality of heating portions 620 may be Not equal to each other. This can make the structure of the heating pipe 60 more reasonable.

Both the upper annealing member 340 and the lower annealing member 350 may be the heating pipe 60 according to the above embodiment of the present invention.
由于3D玻璃制品3被放置在退火支架310上,因此可以直接对3D玻璃制品3进行加热,从而可以使热量更有效地传递到3D玻璃制品3上。因此,与通过加热上模具和下模具来对3D玻璃制品进行退火的技术方案相比,通过利用退火装置30来对3D玻璃制品3进行退火,可以降低能耗,即退火装置30具有能耗低的优点。Since the 3D glass product 3 is placed on the annealing support 310, the 3D glass product 3 can be directly heated, so that heat can be more effectively transferred to the 3D glass product 3. Therefore, compared with the technical solution of annealing the 3D glass product by heating the upper mold and the lower mold, by using the annealing device 30 to anneal the 3D glass product 3, the energy consumption can be reduced, that is, the annealing device 30 has low energy consumption.

上退火板330可以可上下移动地设置,例如可以通过气缸、电缸等驱动上退火板330上下移动。在将3D玻璃制品3放置到退火支架310上或者从退火支架310上取走3D玻璃制品3时,可以使上退火板330向上移动,以便便于搬运3D玻璃制品3。在对3D玻璃制品3进行退火时,可以使上退火板330向下移动,以便加热3D玻璃制品3。The upper annealing plate 330 may be vertically movable. For example, the upper annealing plate 330 may be driven to move up and down by an air cylinder, an electric cylinder, or the like. When the 3D glass product 3 is placed on the annealing support 310 or the 3D glass product 3 is removed from the annealing support 310, the upper annealing plate 330 may be moved upward to facilitate the handling of the 3D glass product 3.

The heating element 422 may be provided on or in the lower heating plate 421. The suction port of the vacuum generator can communicate with the suction channel 4211. The graphite mold 430 may be disposed on the upper surface 4212 of the lower heating plate 421, the graphite mold 430 may be located below the upper heating module 410, and the porosity of the graphite mold 430 may be 12% or more.
下面参考图1、图2和图4-图11所示描述根据本发明实施例的3D玻璃热弯机1的工作过程。The working process of the 3D glass bending machine 1 according to the embodiment of the present invention is described below with reference to FIGS. 1, 2 and 4-11.
首先,将玻璃板2搬运到预热腔111内,利用预热装置20对玻璃板2进行预热。具体而言,玻璃板2被放置在预热支架210上,然后利用上预热件240和下预热件250对玻璃板2进行加热。其中,预热温度可以根据玻璃板2的成分确定,这与现有技术并无本质区别,因此不再详细地描述。First, the glass plate 2 is carried into the preheating cavity 111, and the glass plate 2 is preheated by the preheating device 20. Specifically, the glass plate 2 is placed on the preheating bracket 210, and then the glass plate 2 is heated by the upper preheating member 240 and the lower preheating member 250. The preheating temperature can be determined according to the composition of the glass plate 2, which is not fundamentally different from the prior art, and therefore will not be described in detail.
预热结束后,将玻璃板2搬运到热弯腔112内,利用3D玻璃热弯装置40加热玻璃板2。具体而言,玻璃板2可以被放置在石墨模具430上,利用上加热模组410和下加热模组420对石墨模具430进行加热。其中,玻璃板2的预设部分(待热弯部分)可以与第一加热件413相对,例如玻璃板2的该预设部分可以在上下方向上与第一加热件413相对,以便利用第一加热件413加热玻璃板2的该预设部分。After the preheating is completed, the glass plate 2 is transported into the bending chamber 112, and the glass plate 2 is heated by the 3D glass bending device 40. Specifically, the glass plate 2 can be placed on the graphite mold 430, and the graphite mold 430 is heated by using the upper heating module 410 and the lower heating module 420. The preset portion (the portion to be bent) of the glass plate 2 may be opposed to the first heating member 413. For example, the preset portion of the glass plate 2 may be opposed to the first heating member 413 in the up-down direction in order to use the first The heating member 413 heats the predetermined portion of the glass plate 2.
在利用3D玻璃热弯装置40加热玻璃板2之前、之后或同时,可以向热弯腔112内提供惰性气体,并开启该真空发生器以便抽真空。由于该真空发生器的抽气口通过抽气通道4211与石墨模具430的气孔连通,因此开启该真空发生器后,惰性气体进入到石墨模具430的气孔内。此时,玻璃板2的该预设部分受到其自身重力、惰性气体的压力(作用在玻璃板2的上表面上)和负压力(作用在玻璃板2的下表面上)。Before, after, or at the same time as the glass plate 2 is heated by the 3D glass bending device 40, an inert gas may be supplied into the bending chamber 112, and the vacuum generator may be turned on to evacuate. Since the suction port of the vacuum generator is in communication with the pores of the graphite mold 430 through the suction channel 4211, after the vacuum generator is turned on, the inert gas enters the pores of the graphite mold 430. At this time, the predetermined portion of the glass plate 2 is subjected to its own gravity, the pressure of the inert gas (acting on the upper surface of the glass plate 2), and the negative pressure (acting on the lower surface of the glass plate 2).
当玻璃板2的该预设部分的温度上升到玻璃板2的变形点温度以上时,玻璃板2的该预设部分在其自身重力、惰性气体的压力和该负压力的作用下,快速地发生变形(向下移动),直至贴合在石墨模具430的上表面上(此时整个玻璃板2都贴合在石墨模具430的上表面上),以便形成3D玻璃制品3。When the temperature of the preset portion of the glass plate 2 rises above the temperature of the deformation point of the glass plate 2, the preset portion of the glass plate 2 is rapidly affected by its own gravity, the pressure of the inert gas, and the negative pressure Deformation (moves downward) until it is attached to the upper surface of the graphite mold 430 (at this time, the entire glass plate 2 is attached to the upper surface of the graphite mold 430) to form a 3D glass product 3.
现有的用于3D玻璃的模具可以是金属模具、石墨模具。由于现有的热弯方法是将玻璃板加热到变形点温度,然后利用上模具和下模具挤压玻璃板(模压),以便玻璃板变形、进而形成3D玻璃制品,因此上模具和下模具需要承受较大的作用力,这就要求上模具和下模具具有较高的结构强度。由此当上模具和下模具为石墨模具时,石墨模具的气孔率小于等于3%,以便保证石墨模具具有较高的结构强度。更为重要的是,为了提高石墨模具的结构强度,本领域技术人员的普遍追求是进一步降低石墨模具的气孔率。Existing molds for 3D glass can be metal molds and graphite molds. Because the existing hot bending method is to heat the glass plate to the temperature of the deformation point, and then use the upper mold and the lower mold to squeeze the glass plate (molding), so that the glass plate is deformed to form a 3D glass product, so the upper mold and the lower mold require Withstanding large forces, this requires higher structural strength of the upper and lower molds. Therefore, when the upper mold and the lower mold are graphite molds, the porosity of the graphite molds is less than or equal to 3%, so as to ensure that the graphite molds have higher structural strength. More importantly, in order to improve the structural strength of the graphite mold, the general pursuit of those skilled in the art is to further reduce the porosity of the graphite mold.
而在本申请中,由于将玻璃板2加热到玻璃板2的变形点温度以上(例如接近玻璃板2的软化点温度)、且使玻璃板2受到惰性气体的压力和该负压力的作用,因此无需利用上模具和下模具挤压玻璃板2。也就是说,可以只设置位于玻璃板2下方的石墨模具430,且石墨模具430受到的作用力非常小,因此石墨模具430的气孔率可以大于等于12%。In the present application, because the glass plate 2 is heated to a temperature above the deformation point of the glass plate 2 (for example, near the softening point temperature of the glass plate 2), and the glass plate 2 is subjected to the pressure of an inert gas and the negative pressure, Therefore, it is not necessary to press the glass plate 2 with the upper mold and the lower mold. That is, only the graphite mold 430 located under the glass plate 2 can be provided, and the acting force received by the graphite mold 430 is very small, so the porosity of the graphite mold 430 can be greater than or equal to 12%.
优选地,石墨模具430的气孔率可以小于等于40%。更加优选地,石墨模具430的气孔率大于等于15%且小于等于30%。进一步优选地,石墨模具430的气孔率大于等于18%且小于等于25%。最优选地,石墨模具430的气孔率可以是23%。由此不仅可以确保石墨模具430具有足够的结构强 度,而且可以使玻璃板2被更加牢固地吸附在石墨模具430上。Preferably, the porosity of the graphite mold 430 may be 40% or less. More preferably, the porosity of the graphite mold 430 is 15% or more and 30% or less. Further preferably, the porosity of the graphite mold 430 is 18% or more and 25% or less. Most preferably, the porosity of the graphite mold 430 may be 23%. This not only ensures that the graphite mold 430 has sufficient structural strength, but also enables the glass plate 2 to be more firmly adsorbed on the graphite mold 430.
而且,由于不再利用上模具和下模具挤压玻璃板2,玻璃板2的该预设部分在其自身重力、惰性气体的压力和该负压力的作用下热弯变形,因此可以极大地减小玻璃板2受到的压力,由此石墨模具430的表面缺陷(例如表面粗糙度较高、模具颗粒较大等)不会转移到玻璃板2和3D玻璃制品3的表面上,从而可以极大地提高3D玻璃制品3的表面质量。Moreover, since the upper and lower molds are no longer used to squeeze the glass plate 2, the preset portion of the glass plate 2 is deformed by bending under the action of its own gravity, the pressure of the inert gas, and the negative pressure, so it can be greatly reduced. The pressure on the small glass plate 2 is such that the surface defects of the graphite mold 430 (such as higher surface roughness, larger mold particles, etc.) will not be transferred to the surface of the glass plate 2 and the 3D glass product 3, which can greatly Improve the surface quality of 3D glass products 3.
此外,由于无需设置上模具,从而不仅可以简化3D玻璃热弯装置40和3D玻璃热弯机1的结构,而且可以使上加热模组410直接对玻璃板2进行加热,从而可以使热量更有效地传递到玻璃板2上。由此可以降低上加热模组410和3D玻璃热弯装置40的能耗,即上加热模组410和3D玻璃热弯装置40具有能耗低的优点。In addition, since the upper mold is not required, the structure of the 3D glass bending device 40 and the 3D glass bending machine 1 can be simplified, and the upper heating module 410 can directly heat the glass plate 2 so that the heat can be more effective. The ground is transferred to the glass plate 2. Therefore, the energy consumption of the upper heating module 410 and the 3D glass bending device 40 can be reduced, that is, the upper heating module 410 and the 3D glass bending device 40 have the advantage of low energy consumption.
根据本发明实施例的3D玻璃热弯装置40通过在下加热板421上设置抽气通道4211、且将石墨模具430设置在下加热板421的上表面4212上,从而不仅可以使惰性气体进入到石墨模具430内以便防止石墨模具430氧化,而且可以极大地减小玻璃板2受到的压力,从而避免将石墨模具430的表面缺陷转移到玻璃板2和3D玻璃制品3的表面上,以便可以极大地提高3D玻璃制品3的表面质量。The 3D glass hot bending device 40 according to the embodiment of the present invention not only allows inert gas to enter the graphite mold by providing an exhaust channel 4211 on the lower heating plate 421 and a graphite mold 430 on the upper surface 4212 of the lower heating plate 421. 430 in order to prevent the graphite mold 430 from oxidizing, and the pressure on the glass plate 2 can be greatly reduced, so as to avoid transferring the surface defects of the graphite mold 430 to the surface of the glass plate 2 and the 3D glass product 3, so as to greatly improve Surface quality of 3D glass products 3.
因此,根据本发明实施例的3D玻璃热弯装置40具有使用寿命长、加工质量高等优点。Therefore, the 3D glass bending device 40 according to the embodiment of the present invention has the advantages of long service life, high processing quality, and the like.
优选地,可以在利用3D玻璃热弯装置40加热玻璃板2之前,向热弯腔112内提供惰性气体且开启该真空发生器以便抽真空,在负压作用下,惰性气体被充分地吸入到石墨模具430的内部。换言之,在石墨模具430没有受热之前,惰性气体已经被充分地吸入到石墨模具430的内部。由此可以更加有效地避免石墨模具430被氧化,更加有效地避免石墨模具430因氧化而外形变化、强度降低、使用寿命缩短。Preferably, before the glass plate 2 is heated by the 3D glass bending device 40, an inert gas is supplied into the bending chamber 112 and the vacuum generator is turned on so as to be evacuated. Under a negative pressure, the inert gas is fully sucked into The inside of the graphite mold 430. In other words, before the graphite mold 430 is not heated, the inert gas has been sufficiently sucked into the inside of the graphite mold 430.

发明人经过深入地研究后发现:在现有的玻璃热弯过程中,随着热弯的进行,玻璃的热弯部分与上加热模组的距离逐步拉大,导致上加热模组向玻璃的热弯部分提供的热量随着该热弯部分向下移动而减小。直到玻璃的热弯部分与下加热模组的距离接近到一定程度后,下加热模组向玻璃的热弯部分提供的热量才能逐步增强。由此导致玻璃的热弯部分吸收的热量呈周期性变化,从而导致玻璃的热弯表面质量差、热弯速度慢。After in-depth research, the inventor found that in the existing process of glass bending, as the bending of the glass progresses, the distance between the heated portion of the glass and the upper heating module gradually increases, resulting in the upper heating module facing the glass. The heat provided by the bent portion decreases as the bent portion moves downward. The heat provided by the lower heating module to the bent portion of the glass can be gradually increased until the distance between the bent portion of the glass and the lower heating module is close to a certain degree. As a result, the heat absorbed by the hot-bent portion of the glass changes periodically, resulting in poor quality of the hot-bent surface of the glass and a slow hot-bend speed.
在玻璃板2的该预设部分受热弯曲过程中,该预设部分向下移动以便实现弯曲。由于第一加热件413可上下移动地设置,因此可以向下移动第一加热件413,以便使第一加热件413与玻璃板2的该预设部分之间的距离保持不变。也就是说,第一加热板411与该预设部分可以同步移动以便第一加热件413与该预设部分的距离保持不变,直至玻璃板2贴合在石墨模具430的上表面上,以便形成3D玻璃制品3。During the heating and bending process of the preset portion of the glass plate 2, the preset portion is moved downward to achieve bending. Since the first heating member 413 is movably arranged up and down, the first heating member 413 can be moved downward so as to keep the distance between the first heating member 413 and the preset portion of the glass plate 2 constant. That is, the first heating plate 411 and the preset portion can be moved synchronously so that the distance between the first heating element 413 and the preset portion remains unchanged until the glass plate 2 is attached to the upper surface of the graphite mold 430 so that Forming a 3D glass article 3.
由此可以使玻璃板2的该预设部分吸收的热量基本保持恒定,从而可以避免玻璃板2的该预设部分的温度随着该预设部分与第一加热件413的远近不同而出现周期性变化。由此可以提高玻璃板2的该预设部分的受热均匀性,即在热弯过程中,第一加热件413向玻璃板2的该预设部分提供的热量不会随着该预设部分向下移动而减小,从而可以提高玻璃板2的热弯表面质量和热弯速度。Thereby, the heat absorbed by the preset portion of the glass plate 2 can be kept substantially constant, so that the temperature of the preset portion of the glass plate 2 can be prevented from occurring as the preset portion is different from the first heating element 413. Sexual change. As a result, the uniformity of the heating of the preset portion of the glass plate 2 can be improved, that is, during the heat bending process, the heat provided by the first heating member 413 to the preset portion of the glass plate 2 will not follow the preset portion. It is reduced by moving downward, so that the heat bending surface quality and heat bending speed of the glass plate 2 can be improved.
玻璃板2与石墨模具430完全贴合后,第一加热件413不再移动,按预定程序对3D玻璃制品3(玻璃板2)保温一定时间后,第一加热件413向上移动恢复初始位置(初始状态)。After the glass plate 2 and the graphite mold 430 are completely attached, the first heating member 413 is no longer moved. After the 3D glass product 3 (glass plate 2) is maintained for a predetermined time according to a predetermined procedure, the first heating member 413 is moved upward to restore the original position ( Initial state).
根据本发明实施例的上加热模组410、3D玻璃热弯装置40和3D玻璃热弯机1通过使第一加热件413可上下移动地设置,从而在对玻璃板2进行热弯时,可以使第一加热件413与玻璃板2的该 预设部分同步移动以便使第一加热件413与该预设部分的距离保持不变。According to the embodiment of the present invention, the upper heating module 410, the 3D glass bending device 40, and the 3D glass bending machine 1 are arranged to be movable up and down, so that when the glass plate 2 is bent, it can be The first heating element 413 is moved synchronously with the preset portion of the glass plate 2 so that the distance between the first heating element 413 and the preset portion remains unchanged.
由此可以提高玻璃板2的该预设部分的受热均匀性,即在热弯过程中,第一加热件413向玻璃板2的该预设部分提供的热量不会随着该预设部分向下移动而减小,从而可以提高玻璃板2的热弯表面质量和热弯速度。与现有技术相比,通过使用根据本发明实施例的上加热模组410、3D玻璃热弯装置40和3D玻璃热弯机1,可以将玻璃板2的热弯速度提高10%左右。As a result, the uniformity of the heating of the preset portion of the glass plate 2 can be improved, that is, during the heat bending process, the heat provided by the first heating member 413 to the preset portion of the glass plate 2 will not follow the preset portion. It is reduced by moving downward, so that the heat bending surface quality and heat bending speed of the glass plate 2 can be improved. Compared with the prior art, by using the upper heating module 410, the 3D glass bending device 40, and the 3D glass bending machine 1 according to the embodiment of the present invention, the bending speed of the glass plate 2 can be increased by about 10%.
因此,根据本发明实施例的上加热模组410、3D玻璃热弯装置40和3D玻璃热弯机1具有热弯表面质量好、热弯速度快等优点。Therefore, the upper heating module 410, the 3D glass hot bending device 40, and the 3D glass hot bending machine 1 according to the embodiment of the present invention have the advantages of good quality of the heat-bent surface, fast heat-bending speed, and the like.
继续通入惰性气体(即持续通入惰性气体),保温结束后,开始降低贴合在石墨模具430的上表面上的3D玻璃制品3的温度,当3D玻璃制品3的温度降至3D玻璃制品3的应变点温度以下后,关闭真空发生器。由此可以防止3D玻璃制品3在降温过程中不发生变形。Continue to pass inert gas (that is, continue to pass inert gas). After the heat preservation is over, start to reduce the temperature of the 3D glass product 3 attached to the upper surface of the graphite mold 430. When the temperature of the 3D glass product 3 drops to the 3D glass product When the strain point temperature is below 3, turn off the vacuum generator. This can prevent the 3D glass product 3 from being deformed during the cooling process.
热弯结束后,将3D玻璃制品3搬运到退火腔113内,利用退火装置30对3D玻璃制品3进行退火。其中,退火温度可以根据玻璃板2的成分确定,这与现有技术并无本质区别,因此不再详细地描述。After the heat bending is finished, the 3D glass product 3 is transferred into the annealing chamber 113, and the 3D glass product 3 is annealed by the annealing device 30. The annealing temperature may be determined according to the composition of the glass plate 2, which is not fundamentally different from the prior art, and therefore will not be described in detail.
如图1和图2所示,3D玻璃热弯机1可以进一步包括气罩50,气罩50在打开位置与关闭位置之间可上下移动地设在热弯腔112内。例如,可以利用气缸或电缸驱动气罩50沿上下方向移动。位于该关闭位置的气罩50可以与热弯腔112的壁面配合,位于该关闭位置的气罩50与热弯腔112的壁面之间可以限定出惰性气体腔,3D玻璃热弯装置40可以位于该惰性气体腔内,位于该打开位置的气罩50可以脱离热弯腔112的壁面。As shown in FIG. 1 and FIG. 2, the 3D glass bending machine 1 may further include an air hood 50, and the air hood 50 is disposed in the hot bending chamber 112 so as to be movable up and down between an open position and a closed position. For example, the air hood 50 may be driven to move in the vertical direction by an air cylinder or an electric cylinder. The air hood 50 in the closed position may cooperate with the wall surface of the hot bending cavity 112. The inert gas chamber may be defined between the air hood 50 in the closed position and the wall surface of the hot bending cavity 112. The 3D glass hot bending device 40 may be located at In the inert gas chamber, the air hood 50 located in the open position can be separated from the wall surface of the thermal bending chamber 112.
具体而言,在将玻璃板2放置到石墨模具430上后,可以使气罩50向下移动到该关闭位置。由于3D玻璃热弯装置40位于体积较小的该惰性气体腔内,因此不仅可以减少惰性气体的用量,而且可以进一步减少热量损失。热弯结束后,可以使气罩50向上移动到该打开位置,以便取走3D玻璃制品3。Specifically, after the glass plate 2 is placed on the graphite mold 430, the air hood 50 can be moved down to the closed position. Since the 3D glass bending device 40 is located in the inert gas cavity with a small volume, not only the amount of inert gas can be reduced, but also the heat loss can be further reduced. After the heat bending is completed, the air hood 50 can be moved upward to the open position so as to remove the 3D glass product 3.
石墨模具430的下表面的形状与下加热板421的上表面4212的形状适配。由此可以使3D玻璃热弯装置40的结构更加合理。The shape of the lower surface of the graphite mold 430 is adapted to the shape of the upper surface 4212 of the lower heating plate 421. Therefore, the structure of the 3D glass bending apparatus 40 can be made more reasonable.
如图10和图11所示,下加热板421的上表面4212上设有凹槽4213,抽气通道4211的上端口开设在凹槽4213的底壁面上。由此可以对石墨模具430的更多的表面进行抽吸惰性气体,从而不仅可以使更多的惰性气体进入到石墨模具430内,而且可以使玻璃板2能够被更加牢固地吸附在石墨模具430上。As shown in FIG. 10 and FIG. 11, a groove 4213 is provided on the upper surface 4212 of the lower heating plate 421, and an upper port of the exhaust channel 4211 is opened on the bottom wall surface of the groove 4213. As a result, more surfaces of the graphite mold 430 can be sucked with inert gas, so that not only can more inert gas enter the graphite mold 430, but also the glass plate 2 can be more firmly adsorbed on the graphite mold 430. on.
优选地,抽气通道4211可以是多个,多个抽气通道4211可以构成多个抽气通道组,每个该抽气通道组可以包括多个抽气通道4211。其中,多个该抽气通道组可以沿下加热板421的横向和纵向中的一者间隔开地设置,每个该抽气通道组的多个抽气通道4211可以沿下加热板421的横向和纵向中的另一者间隔开地设置。Preferably, there may be multiple extraction channels 4211, and multiple extraction channels 4211 may constitute multiple extraction channel groups, each of which may include multiple extraction channels 4211. Wherein, a plurality of the extraction channel groups may be spaced apart along one of the horizontal and vertical directions of the lower heating plate 421, and the plurality of extraction channels 4211 of each of the extraction channel groups may be horizontally aligned along the lower heating plate 421. Set apart from the other in the vertical direction.
其中,当玻璃板2被放置在石墨模具430上时,下加热板421的横向可以与玻璃板2的长度方向和宽度方向中的一个一致,下加热板421的纵向可以与玻璃板2的长度方向和宽度方向中的另一个一致。Among them, when the glass plate 2 is placed on the graphite mold 430, the lateral direction of the lower heating plate 421 may be consistent with one of the length direction and the width direction of the glass plate 2, and the longitudinal direction of the lower heating plate 421 may be the same as the length of the glass plate 2. The other direction is the same as the width direction.
如图10和图11所示,抽气通道4211的下端口可以开设在下加热板421的下表面上,由此可以使3D玻璃热弯装置40的结构更加合理。As shown in FIG. 10 and FIG. 11, the lower port of the suction channel 4211 can be opened on the lower surface of the lower heating plate 421, so that the structure of the 3D glass hot bending device 40 can be more reasonable.

当需要从石墨模具430上取走3D玻璃制品3时,使该第一开口与该第三开口连通,然后可以利用该惰性气体源通过抽气通道4211向石墨模具430提供正压的惰性气体。由此可以防止3D玻璃制品3与石墨模具430发生粘连,从而可以更加方便地、更加容易地从石墨模具430上取走3D玻璃制品3。When the 3D glass product 3 needs to be removed from the graphite mold 430, the first opening is communicated with the third opening, and then the inert gas can be provided to the graphite mold 430 through the exhaust channel 4211 by using the inert gas source. This can prevent the 3D glass product 3 from adhering to the graphite mold 430, so that the 3D glass product 3 can be more conveniently and easily removed from the graphite mold 430.

This can prevent the first heating plate 411 and the second heating plate 412 from interfering with each other when the first heating plate 411 is pivoted relative to the second heating plate 412.
