Description

一种增强增韧复合管的成型设备 技术领域
本发明属于管道生产设备技术领域，涉及一种紧固件，特别是一种防松螺母。
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，提出了一种增强增韧复合管的成型设备，本发明解决的技术问题是：如何使成型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：一种增强增韧复合管的成型设备，包括成型模具，其特征在于，本成型设备还包括外管支架、水平设置的外管和能够将增强纤维包覆在外管外周壁上的绕线机，所述外管的尾端伸入成型模具内，且外管外壁上的增强纤维能够与成型模具内注入的熔融料复合形成复合管道并从成型模具的出口伸出，所述外管的首端连接在外管支架上，所述外管支架的底部连接有嵌入件，所述嵌入件具有位于外管支架下方的弯钩部。
在进行管道生产的过程中，都需要利用牵引机向前牵拉制造成型的管道，以使管道连续不断地从成型模具内伸出，实现连续生产。本成型设备中，绕线机直接将增强纤维包覆在外管的外周壁上，与熔融料在成型模具内进行结合，之后形成纤维增强复合管道从成型模具的出口端伸入，然后再进行定型冷却。显然，本复合管的成型设备与现有设备的生产原理完全不同，本成型设备 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。
而针对于本成型设备特殊的管道成型方式，由于牵引机牵拉力很大，通常能达到几十吨的牵拉力，同时由于连续的增强纤维包覆在外管的外周壁上，因此牵引的牵拉力会通过增强纤维传递给外管，导致外管具有移动的趋势，然而，对于管道成型而言，即便外管出现微量的移动，也会影响产品的质量。此时，通过设置外管支架，不仅实现了外管首端的安装，而且通过在外管支架的底部连接嵌入件，而嵌入件具有有位于外管支架下方的弯钩部，这样在进行设备安装的过程中，便可以将嵌入件预先浇筑于混凝土地面内，进而具有较强的抓地力，使得外管支架具有较高的稳定性而不会由于牵拉力的作用而出现横向的平移，保证设备运转过程中外管不会出现移动，外管与成型模具之间保持较高的配合精度，进而保证产品的质量。
在上述的增强增韧复合管的成型设备中，所述外管支架的底部具有水平设置的底板，所述嵌入件包括竖向设置的杆状部和连接在杆状部下端的弯钩部，所述杆状部的上端与底板固定连接。杆状部的设置一方面便于与底板进行连接，另外一方面能使弯钩部埋入地面以下较深的位置，避免埋入较浅的情况下存在地面开裂的情况。
在上述的增强增韧复合管的成型设备中，所述底板呈矩形且至少在底板的两条侧边上分别设有上述的嵌入件。成型模具、绕线机、外管支撑架以及挤出机沿外管的轴线方向依次布置。作为优选，底板靠近模具方向的侧边以及左右两侧边上分别设有至少 一个上述的嵌入件。通过该设计使得底板的多条侧边均受到了嵌入件的固定，进而通过多个不同位置的嵌入件来进一步提升外管支架的稳定性，避免牵拉力作用引起外管支架以及外管出现移动的情况，保证产品质量高。
在上述的增强增韧复合管的成型设备中，所述底板上开设有供杆状部的上端穿过的过孔，所述杆状部的上端螺纹连接有压紧在底板顶面上的螺帽一。该设计能便于嵌入件的安装，使得制造方便、成本低。
在上述的增强增韧复合管的成型设备中，本成型设备还包括挤出机和穿设在外管内的芯管，所述成型模具包括外模套和芯模，外模套与芯模之间形成有成型腔道，所述挤出机的出料口上连接有出料管，所述芯管的首端固定连接在外管支架上且与出料管相连通，所述芯管的尾端伸入成型模具内并与成型模具的成型腔道相连通，所述外管和芯管均与外模套同轴心设置。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。
在上述的增强增韧复合管的成型设备中，所述外管支架还包括架体，外管的首端和芯管的首端均连接在架体上，所述架体的底部具有水平设置的支撑板，所述支撑板和底板之间铺设有橡胶垫，所述支撑板的边沿穿设有若干竖向设置的调节螺栓，所述底板上设有若干与各调节螺栓一一对应的螺帽二，各调节螺栓的杆部穿过支撑板与对应的螺帽二螺纹连接，且调节螺栓的头部抵靠在支撑板的顶面上。制成管道的成型模具通常都是水平放置的，因此外管和芯管要想与成型模具的外模套保持同心，首先得保证 外管和芯管的水平度。此时，通过该设计，目的在于使架体的高度能进行调节，进而调节外管和芯管首端的高度，以保证外管和芯管的水平度。具体的，通过拧紧调节螺栓，能向下压紧橡胶垫，此时依靠橡胶垫的微量变形，使得支撑板向下进行微量移位，外管和芯管的首端向下微量降低；反之，当拧松调节螺栓时，橡胶垫能反弹变形，将支撑板向上顶起，使外管和芯管的首端向上微量抬高。
在上述的增强增韧复合管的成型设备中，所述支撑板呈矩形且至少在其相互平行的两条侧边上分别设有上述的调节螺栓，所述底板的底面上开设有若干与各螺帽二一一对应的沉孔，各螺帽二设置在对应的沉孔内，螺帽二与沉孔的孔底之间还设有垫片。作为优选，支撑板靠近模具方向的侧边以及左右两侧边上分别设有三个上述的调节螺栓。牵引机的牵拉力会通过外管传递给架体，因此底板与支撑板之间的连接也需要能承受该牵拉力的作用。而支撑板与底板之间具有较多的调节螺栓进行连接，这样的设计一方面依靠多个调节螺栓来保证底板与支撑板之间连接稳定性好，不会由于牵拉力的作用而出现松动的情况；另一方面，该设计还使得在调节过程中，根据实际情况，可以选择调节部分调节螺栓，来调节支撑板的高度或者水平度，进而达到更高的调节精度，使调节之后能保证外管和芯管与外模套之间具有较高的同心度。
在上述的增强增韧复合管的成型设备中，所述外管的首端具有连接法兰一，所述外管支架上固连有竖向设置的连接板，所述连接法兰一的端面与连接板的侧面相贴靠，连接法兰一上沿周向设有若干与连接板螺纹连接的螺栓一。由于外管与外管支架之间的连接结构，也需要承受牵拉力的作用。因此，通过在外管支架上竖向设置连接板，同时在外管的首端设置连接法兰一，连接法兰一与连接板通过多个螺栓一连接，保证外管与外管支架之间连接稳定性好，进而能抵抗较大的牵拉力而不会出现松动的情况， 避免由于外管的松动、移位引起的外管与成型模具配合精度的降低，从而保证产品质量好。
在上述的增强增韧复合管的成型设备中，所述连接板上开设有安装孔，所述芯管的首端具有连接法兰二，所述芯管的首端插接在安装孔内且连接法兰二与连接板的侧面相贴靠，连接法兰二上沿周向设有若干与连接板螺纹连接的螺栓二，所述出料管的出口端伸入安装孔内并与芯管的端口相插接。芯管的首端插接在安装孔内，安装孔对芯管具有定位效果，在此基础上，芯管首端的连接法兰二通过螺栓二连接在连接板上，能进一步提升了芯管的稳定性，使设备在运转中，芯管稳定性好，能有效保证其与外管以及外模套之间的同心度，进而保证成型腔道周向上熔融料分布均匀，进而使制成的复合管道管壁均匀、质量好。
在上述的增强增韧复合管的成型设备中，所述安装孔为台阶孔，所述连接法兰二的端面上具有与台阶孔的大口径段配合插接的环形凸起部，所述环形凸起部的内径与台阶孔小口径段的内径相同，所述出料管的出口端与台阶孔的小口径段以及环形凸起部匹配插接。台阶孔与环形凸起部相配合，这样台阶孔对芯管形成了支撑和径向上的定位，保证芯管安装的稳定性好，避免芯管移位对复合管道成型质量的影响。环形凸起部的内径与台阶孔小口径段的内径相同，使得出料管的出口端与台阶孔的小口径段以及环形凸起部匹配插接，这样的设计使出料管具有较大的插接深度，稳定性好，能保证其稳定地向芯管输送熔融料。
与现有技术相比，本增强增韧复合管的成型设备具有以下优点：
1、本成型设备通过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。
2、通过在外管支架上设置埋设于地面下的嵌入件，使得外管支架具有较高的稳定性而不会由于牵拉力的作用而出现横向的平移，保证设备运转过程中外管不会出现移动，外管与成型模具之间保持较高的配合精度，进而保证产品的质量。
3、本成型设备通过一步法制造成型，具有生产效率高的优点，而且能缩短流水线的长度，使设备占用场地小。

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一实施例。
如图1和图2所示，本增强增韧复合管的成型设备包括成型模具1、挤出机7、外管支架2、水平设置的外管3和能够将增强纤维包覆在外管3外周壁上的绕线机4，外管3内穿设有芯管12，挤出机7的出料口上连接有出料管8，芯管12的首端与出料管8相连通，芯管12与挤出机7连通之后能向成型模具内提供熔融料，如融料的PE。外管3的尾端伸入成型模具1内，且外管3外壁上的增强纤维能够与成型模具1内注入的熔融料复合形成复合管道并从成型模具1的出口伸出，外管3的首端连接在外管支架2上。
如图3所示，外管支架2还包括架体22和位于底部的水平设置的底板21，底板21呈矩形，外管3的首端和芯管12的首端均连接在架体22上，底板21上连接有6个埋设于地面下的嵌入件5，具体的，底板21靠近模具方向的侧边上、底板21的左侧边和底板21的右侧板上分别设置两个嵌入件5。通过该设计使得底板21的多条侧边均受到了嵌入件5的固定，进而通过多个不同位置的嵌入件5来进一步提升外管支架2的稳定性，避免牵拉力作用引起外管支架2以及外管3出现移动的情况，保证产品质量高。
如图4所示，嵌入件5包括竖向设置的杆状部51和连接在杆状部51下端的弯钩部52，杆状部51的上端穿出地面与底板21固定连接。具体的，底板21上开设有供杆状部51的上端穿过的过孔211，杆状部51的上端螺纹连接有压紧在底板21顶面上的螺帽一6。弯钩部52的设置提升了抓地力，使得嵌入件5能承受较大的拉力而不会出现移动，杆状部51的设置使得弯钩部52埋入地面以下较深的位置，避免埋入较浅的情况下存在地面开裂的情况。
如图5所示，架体22的底部具有水平设置的支撑板23，支撑板23呈矩形，支撑板23和底板21之间铺设有橡胶垫24，支撑板23的边沿穿设有九个竖向设置的调节螺栓9，底板21上设 有若干与各调节螺栓9一一对应的螺帽二17，各调节螺栓9的杆部穿过支撑板23与对应的螺帽二17螺纹连接，且调节螺栓9的头部抵靠在支撑板23的顶面上。具体的，如图4所示，支撑板23靠近模具方向的侧边以及左右两侧边上分别设有三个调节螺栓9，如图6所示，底板21的底面上开设有若干与各螺帽二17一一对应的沉孔212，各螺帽二17设置在对应的沉孔212内，螺帽二17与沉孔212的孔底之间还设有垫片10，垫片10优选采用放松垫片10。通过拧紧调节螺栓9，能向下压紧橡胶垫24，此时依靠橡胶垫24的微量变形，使得支撑板23向下进行微量移位，外管3和芯管12的首端向下微量降低；反之，当拧松调节螺栓9时，橡胶垫24能反弹变形，将支撑板23向上顶起，使外管3和芯管12的首端向上微量抬高。通过该设计，目的在于使架体22的高度能进行调节，进而调节外管3和芯管12首端的高度，以保证外管3和芯管12的水平度。作为优选，如图2所示，成型模具1与绕线机4之间还设有支撑座15，支撑座15上设有滚轮16，滚轮16的转动轴心线与外管3的轴心线垂直，通过滚轮16的转动，能对外管3外周壁上的增强纤维进行支撑。
如图7所示，外管3的首端具有连接法兰一31，外管支架2上固连有竖向设置的连接板25，连接法兰一31的端面与连接板25的侧面相贴靠，连接法兰一31上沿周向设有若干与连接板25螺纹连接的螺栓一11。连接法兰一31与连接板25通过多个螺栓一11连接，保证外管3与外管支架2之间连接稳定性好，进而能抵抗较大的牵拉力而不会出现松动的情况，避免由于外管3的松动、移位引起的外管3与成型模具1配合精度的降低，从而保证产品质量好。
如图7所示，连接板25上开设有安装孔251，芯管12的首端具有连接法兰二121，芯管12的首端插接在安装孔251内且连接法兰二121与连接板25的侧面相贴靠，连接法兰二121上沿周 向设有若干与连接板25螺纹连接的螺栓二13，出料管8的出口端伸入安装孔251内并与芯管12的端口相插接。进一步的，安装孔251为台阶孔，连接法兰二121的端面上具有与台阶孔的大口径段配合插接的环形凸起部122，环形凸起部122的内径与台阶孔小口径段的内径相同，出料管8的出口端与台阶孔的小口径段以及环形凸起部122匹配插接。环形凸起部122的内径与台阶孔小口径段的内径相同，使得出料管8的出口端与台阶孔的小口径段以及环形凸起部122匹配插接，这样的设计使出料管8具有较大的插接深度，稳定性好，能保证其稳定地向芯管12输送熔融料。
如图8所示，成型模具1包括外模套1a，外模套1a内设有芯模1b以及固连在芯模1b前端的分流器1d，分流器1d则通过螺栓连接在芯管12尾端处的支撑套14上，外管3和芯管12均与外模套1a同轴心设置。外模套1a与芯模1b之间形成有成型腔道1c，芯管12的尾端伸入成型模具1内且与分流器1d正对，使得芯管12流出的熔融料能依靠分流器1d分流径向向四周扩散，以均匀地流动至成型腔道1c内。外管3的外周壁与外模套1a的内周壁之间形成与成型腔道1c正对的环形腔道1e，使得外管3外周壁上的增强纤维层能够穿过成型腔道1c，与熔融料在成型腔道1c内进行结合。
本增强增韧复合管的生产设备在制造时，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7挤出熔融料如，进入芯管12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12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。
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。
