Description

一种复合管生产设备 技术领域
本发明属于复合管道技术领域，涉及一种复合管生产设备。
背景技术
随着城市的不断扩大建设、以及石油和天然气的不断开采，对运输管道的需求也越来越大。传统的钢制管道耐腐蚀性较差且不易搬运，已无法适应当前的需要。同时，我国主要石油及天然气多分布于沙漠、沼泽或山区，自然环境较为恶劣，铺设钢制管道时受自然环境的影响十分严重，又由于地面沉降、山体滑坡等原因使输送管道极其容易出现损坏现象。纤维增强复合管道由于其密度小，强度高，具有优异的机械性能，如良好的加工性能及其很好的耐化学稳定性能和耐热性能等，在一些复杂的环境中仍然可以长期稳定使用，因此受到广泛的应用。
现有的纤维增强复合管通常由内而外依次包括内层、增强层与外层三层结构，内层为由塑料挤出机挤出的管坯，增强层为通过缠绕方式缠绕至内层上的增强纤维，以达到提高塑料管道结构强度的目的，外层为附在增强层外的塑料层。而目前制造增强纤维复合管道的设备虽然结构各有不同，但是制造原理上基本一致，主要都是通过挤出机先挤出管坯，然后再通过缠绕机将增强纤维缠绕在管坯表面，并通过粘结剂粘合，形成增强纤维复合管道。如中国专利文献公开的一种塑料管道成型流水线(申请号：201811640324.6；申请公开号：CN109664479A)，该流出线通过第一挤出机内的塑化原料进入成型模具内并使塑化原料成型为内管，然后移经第一定型机能对内管定型冷却，之后依次经过布带机和缠绕机，布带机将第一增强带轴向贴附至内管表面，缠绕机 将第二增强带螺旋缠绕至内管表面。之后，内管移经复合模具内，第二挤出机将塑化原料包覆至内管上并成型为复合管，最后复合管移经第二定型机并定型冷却。该设备所生产的复合管道要保证制备的管道到达要求的强度，通常需要进行多层缠绕，而由于连续纤维的厚度很小，其直接缠绕在内管表面形成的粘结层很小，同时各层纤维依次缠绕往往也会造成纤维之间接触的区域粘接力有限或者根本没有粘结，导致层间的粘结不结实，对复合管道质量尤其是强度的提高效果有限。
发明内容
本发明的目的是针对现有的技术存在上述问题，提出了一种复合管生产设备，本发明解决的技术问题是：如何使生产设备所生产的复合管具有较高的强度以及质量。
本发明的目的可通过下列技术方案来实现：一种复合管生产设备，包括成型模具，所述成型模具的外模套与芯模之间形成有成型腔道，其特征在于，本生产设备还包括支撑座、外管和能将增强纤维包覆在外管外周壁上的绕线机，所述外管的一端伸入外模套内，所述外管的外周壁与外模套的内周壁之间形成与成型腔道正对的环形腔道，所述支撑座上设有位于外管下侧的滚轮，所述滚轮能够对外管外周壁上的增强纤维形成滚动支撑，所述支撑座上还设有能够调节滚轮高度位置的调节结构。
模具成型腔道的作用是供熔融料流过，熔融料在成型腔道内形成所需断面形状的管道后伸出成型模具。本生产设备中，绕线机直接将增强纤维包覆在外管的外周壁上，此时由于外管的一端伸入外模套内，且外管的外周壁与外模套的内周壁之间形成与成型腔道正对的环形腔道，这样的设计能使得外管外周壁上的增强纤维能更为顺畅的进入成型模具内，减少增强纤维进入成型模具的过程中对增强纤维缠绕角度、缠绕张紧力的影响，进而提升复 合管道产品的质量以及强度。同时，外管外周壁上的增强纤维层能够穿过成型腔道，与熔融料在成型腔道内进行结合，之后形成纤维增强复合管道从成型腔道的出口端伸出，然后再进行定型冷却。
针对于本生产设备特殊的管道成型方式，由于增强纤维需要进入成型腔道内与熔融料结合制成复合管，因此外管与外模套需要保证同心度，以使环形腔道与成型腔道正对，增强纤维能顺利通过。为此，本生产设备通过在支撑座上设置滚轮，依靠滚轮对外管外周壁上的增强纤维形成滚动支撑，使得增强纤维被向前牵拉的过程中，滚轮能进行被动转动，进而避免对增强纤维造成硬性摩擦导致产品质量降低，同时，通过调节结构调节滚轮的高度位置，能调节外管相对于外模套的同心度，且生产过程中外管能受到支撑，进而保证生产制造过程外管与外模套始终具有较高的同心度，进而提升产品的质量。
另外，本复合管的生产设备与现有设备的生产原理完全不同，本生产设备并非是先通过挤出机挤出管坯，然后再通过缠绕机将增强纤维缠绕在管坯表面，而是将熔融料以及连续的增强纤维在成型模具内一步成型为复合管道，这样熔融料能够在成型模具内与增强纤维进行相容、渗透，因此结合效果更好，强度更高，而不存在现有设备生产的复合管道存在的层间粘结不结实引起管道强度变弱的问题。
在上述的复合管生产设备中，本生产设备还包括挤出机，所述外管内穿设有芯管，所述芯管、外管和外模套同轴心设置，所述芯管的入口端与所述挤出机连通，所述芯管的出口端伸入外模套内且与成型模具的成型腔道连通。芯管与挤出机连通，使挤出机挤出的熔融料能进入芯管内，而芯管流出的熔融料最终会进入成型模具的成型腔道内。而通过外管内设置芯管，使得芯管、外管和外模套同轴心设置，这样芯管流出的熔融料与增强纤维的移 动方式一致，能够使熔融料在成型腔道内与增强纤维更好的结合，且成型腔道周向上熔融料分布均匀，进而使制成的复合管道质量好。
在上述的复合管生产设备中，所述芯管的外周壁上套设有若干个支撑套，所述支撑套的外周壁抵靠在外管的内周壁上，若干支撑套沿芯管的长度方向与依次间隔设置。芯管流出的熔融料需要在成型模具内沿径向相四周扩散的，因此芯管与外模套之间需要保证较高的同心度，以使扩散均匀，提升产品质量。由于芯管长度较长，通过芯管的长度方向依次设置若干个支撑套，使得芯管受到支撑套的支撑，稳定性得到了保证且始终与外管同轴心设置。而且，支撑套使得芯管和外管相对固定，这样在通过调节机构调节外管高度的过程中，芯管的高度也能同步进行调节，进而保证芯管和外管均与外模套具有较高的同心度。当然，实际操作过程中，若外模套与外管之间水平方向的同心度存在偏差，可以通过调节外模套的水平位置来解决。
在上述的复合管生产设备中，每个支撑套均包括公套和母套，所述芯管为若干根拼接管依次首尾拼接形成，在任意两根拼接管的拼接处，其中一根拼接管的端部套设有上述的公套，另外一根拼接管的端部套设有母套，所述公套和母套之间通过紧固件相固连。本案中，芯管的长度较长，通常能够达到10米以上，而通过若干根拼接管依次首尾拼接形成芯管，避免了一次成型较长的芯管带来的加工复杂、同轴度难以保证的问题。通过在每个拼接处设置公套和母套，公套和母套之间通过紧固件连接，使得相邻拼接管之间的连接不仅稳定性好，而且在各拼接管连接好形成芯管之后，能使得芯管具有较高的同轴度。
在上述的复合管生产设备中，所述母套朝向公套的端面上具有环绕其内孔设置的环形凹肩，所述公套上具有嵌入环形凹肩内的环形凸缘，所述公套上开设有若干沿其周向依次设置的螺栓过 孔，所述母套上开设有若干与螺栓过孔一一对应设置的螺栓孔，每个螺栓过孔内均穿设有上述的紧固件，所述紧固件为螺栓且紧固件穿过螺栓过孔与对应的螺栓孔螺纹连接。公套和母套属于小型零部件，易于保证其加工精度较高。因此，公套和母套之间通过环形凸缘和环形凹肩配合，使得母套和公套能具有较高的配合精度，这样就能保证两根拼接管的拼接具有较高的同轴度。同时，公套和母套之间通过若干螺栓连接，能保证公套和母套连接稳定，设备运转过程中同轴度不会发生改变。
在上述的复合管生产设备中，所述支撑座包括底座和滚轮座，所述底座上设有竖向设置的滑轨，所述滚轮座上连接有与滑轨滑动连接的滑动块，所述滚轮设置在滚轮座的顶部。通过设置滑动块与滑轨滑动连接，依靠滑动块上下移动来带动滚轮进行高度调节，这样的方式使得滚轮上下移动的过程受到了滑轨的导向，使得滚轮高度调节的过程稳定、精度高。
在上述的复合管生产设备中，所述调节结构包括丝杆、蜗杆和与蜗杆相啮合的蜗轮，所述丝杆竖直设置且与滚轮座螺纹连接，所述蜗轮套设在丝杆上且与丝杆周向固定，所述蜗杆上连接有带动蜗杆转动的摇柄。操作时，通过转动摇柄，带动蜗杆转动，进而带动蜗轮以及丝杆同步转动，而由于丝杆与滚轮座螺纹连接，因此丝杆的转动即可实现滚轮座的上下移动。通过蜗轮蜗轮机构配合，实现了减速传动，这样不仅省力，而且在调节完成后能实现自锁，并且能实现滚轮高度位置的微调，能达到较高的调节精度，使得滚轮在对外管外周壁上的增强纤维形成支撑的同时，又不会产生较大的压力导致增强纤维受损，进而保证产品质量高。
在上述的复合管生产设备中，所述滚轮座上设有水平设置的转轴，所述转轴的轴线方向和外管的轴线方向垂直，所述滚轮呈柱状且通过转轴连接在滚轮座上。该设计使得滚轮的转动方向与增强纤维的移动方向一致，加工过程中，滚轮能进行被动转动， 进而避免对增强纤维造成硬性摩擦导致产品质量降低。
在上述的复合管生产设备中，所述外模套内设有分流器，所述芯管的出口端与分流器正对。芯管的出口端与分流器正对，使得分流器能将芯管流出的熔融料沿径向向四周扩散，便于进一步加热塑化，提升增强纤维与熔融料的结合效果，进而提升管道的强度。
在上述的复合管生产设备中，所述芯管的出口端还固定套设有连接套，所述连接套的外周壁抵靠在外管的内周壁上，所述分流器通过螺栓连接在连接套上。通过这样的设计，一方面保证了芯管出口端的稳定性，另一方面实现了分流器的安装，且使得分流器的外周壁与外模套的内周壁形成供增强纤维穿过的间隙。作为优选，连接套上沿其周向开设有八个螺栓过孔，分流器上与开设有八个与螺栓过孔一一对应设置的螺栓孔，每个螺栓过孔内均穿设有螺栓，螺栓穿过螺栓过孔与对应的螺栓孔螺纹连接。
与现有技术相比，本复合管生产设备具有以下优点：
1、本生产设备通过在支撑座上设置滚轮，依靠滚轮对外管外周壁上的增强纤维形成滚动支撑，使得增强纤维被向前牵拉的过程中，滚轮能进行被动转动，进而避免对增强纤维造成硬性摩擦导致产品质量降低，同时，通过调节结构调节滚轮的高度位置，能调节外管相对于外模套的同心度，且生产过程中外管能受到支撑，进而保证生产制造过程外管与外模套始终具有较高的同心度，进而提升产品的质量。
2、本生产设备将熔融料以及连续的增强纤维在成型模具内一步成型为复合管道，这样熔融料能够在成型模具内与增强纤维进行相容、渗透，因此结合效果更好，强度更高，而不存在现有设备生产的复合管道存在的层间粘结不结实引起管道强度变弱的问题。因此，本生产设备所生产的复合管道具有质量好、强度和韧性高的优点。

具体实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
实施例一
如图1、图2和图3所示，本复合管生产设备包括成型模具1、支撑座2、挤出机6、外管3和用于将增强纤维包覆在外管3外周壁上的绕线机4等。外管3内穿设有芯管7，支撑座2上设有位于外管3下侧的滚轮5，滚轮5能够对外管3外周壁上的增强纤维形成滚动支撑，支撑座2上还设有能够调节滚轮5高度位置的调节结构。
如图5所示，成型模具1包括外模套1b，外模套1b内设有 芯模1a、分流器1e，芯模1a与外模套1b之间形成有成型腔道1c，外管3的一端伸入外模套1b内，外管3的外周壁与外模套1b的内周壁之间形成与成型腔道1c正对的环形腔道1d，外模套1b内设有分流器1e，芯管7的出口端与分流器1e正对。芯管7的出口端还固定套设有连接套12，连接套12的外周壁抵靠在外管3的内周壁上，分流器1e通过螺栓连接在连接套12上。通过这样的设计，一方面保证了芯管7出口端的稳定性，另一方面实现了分流器1e的安装，且使得分流器1e的外周壁与外模套1b的内周壁形成供增强纤维穿过的间隙。作为优选，连接套12上沿其周向开设有八个螺栓过孔822，分流器1e上与开设有八个与螺栓过孔822一一对应设置的螺栓孔812，每个螺栓过孔822内均穿设有螺栓，螺栓穿过螺栓过孔822与对应的螺栓孔812螺纹连接。
图4中未示意出支撑座2以及滚轮5。结合图2至图5所示，芯管7、外管3和外模套1b同轴心设置，芯管7的入口端与挤出机6连通，芯管7的出口端伸入外模套1b内且与成型模具1的成型腔道1c连通。芯管7的外周壁上套设有三个支撑套8，支撑套8的外周壁抵靠在外管3的内周壁上，三个支撑套8沿芯管7的长度方向与依次间隔设置。在实际制造过程中，支撑套8的数量可以适当进行调整，如两个、四个或五个。
如图3所示，每个支撑套8均包括公套81和母套82，芯管7为若干根拼接管71依次首尾拼接形成，在任意两根拼接管71的拼接处，其中一根拼接管71的端部套设有上述的公套81，另外一根拼接管71的端部套设有母套82，公套81和母套82之间通过紧固件9相固连。具体的，母套82朝向公套81的端面上具有环绕其内孔设置的环形凹肩821，公套81上具有嵌入环形凹肩821内的环形凸缘811，公套81上开设有若干沿其周向依次设置的螺栓过孔812，母套82上开设有若干与螺栓过孔812一一对应设置 的螺栓孔822，每个螺栓过孔812内均穿设有上述的紧固件9，紧固件9为螺栓且紧固件9穿过螺栓过孔812与对应的螺栓孔822螺纹连接。公套81和母套82属于小型零部件，易于保证其加工精度较高。因此，公套81和母套82之间通过环形凸缘811和环形凹肩821配合，使得母套82和公套81能具有较高的配合精度，这样就能保证两根拼接管71的拼接具有较高的同轴度。同时，公套81和母套82之间通过若干螺栓连接，能保证公套81和母套82连接稳定，设备运转过程中同轴度不会发生改变。
如图6所示，支撑座2包括底座21和滚轮座22，底座21上设有竖向设置的滑轨23，滚轮座22上连接有与滑轨23滑动连接的滑动块24，滚轮5设置在滚轮座22的顶部。滚轮座22上设有水平设置的转轴25，转轴25的轴线方向和外管3的轴线方向垂直，滚轮5呈柱状且通过转轴25连接在滚轮座22上。调节结构包括丝杆10、蜗杆和与蜗杆相啮合的蜗轮，丝杆10竖直设置且与滚轮座22螺纹连接，蜗轮套设在丝杆10上且与丝杆10周向固定，蜗杆上连接有带动蜗杆转动的摇柄11。操作时，通过转动摇柄11，带动蜗杆转动，进而带动蜗轮以及丝杆10同步转动，而由于丝杆10与滚轮座22螺纹连接，因此丝杆10的转动即可实现滚轮座22的上下移动。
本复合管生产设备在制造时，需要依托牵引机将制成形成的复合管道持续地从成型模具1内拉出，以实现连续生产。牵引机为现有技术，图中未示出。挤出机6挤出熔融料如PE，进入芯管7内流至成型模具1内。与此同时，绕线机4将连续增强纤维连续增强纤维沿周向缠绕在外管3的外周壁上，在牵引机的作用下，包覆在外管3外周壁上的增强纤维持续进入成型模具1内，在成型腔道1c内与芯管7流出的熔融料进行结合，之后形成纤维增强复合管道从成型腔道1c的出口端伸入，然后再进行定型冷却。实际制造过程中，还可以设置轴向纱进纱结构，轴向纱进纱结构将 若干沿外管3轴向设置的连续增强纤维包覆在外管3的外周壁上并形成轴向纤维层，而绕线机4将连续增强纤维沿周向缠绕在轴向纤维层的外部。
实施例二
本实施例与实施例一的结构和原理类似，不同的地方在于，如图7所示，调节结构包括调节板13和调节螺栓14，调节板13水平设置且与底座21固连，底座21上设有竖向设置的滑轨23，滚轮座22上连接有与滑轨23滑动连接的滑动块24，滚轮5设置在滚轮座22的顶部。调节螺栓14与调节板13螺纹连接，调节螺栓14竖直设置，调节螺栓14的杆部的尾端端面抵靠在滚轮座22的下端面上。通过转动调节螺栓14，可以使其上下移动，进而带动滚轮座22上下移动，进而调节滚轮5的高度位置。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
