Description

一种非金属复合管管道扩口装置 技术领域
本发明属于塑料管道制造设备技术领域，具体涉及一种非金属复合管管道扩口装置。
背景技术
在油田领域中，输油管道的结垢结蜡现象非常严重，为了减少垢污在管道的连接处粘附，需保证管道整体通径一致。但因为油田中管道公称压力较高，为保证连接强度，只能通过金属扣压这种方式连接。然而金属扣压接头本身壁厚就会导致管道系统在连接处缩径，从而致使垢污极易在连接处粘附。因此需将复合管端部金属扣压接头连接处进行预扩口处理，以此来保证管道系统的通径一致。虽然现有的扩口机种类很多，但是扩口原理基本类似，都是通过动力系统将扩口模具塞入软化的塑料管端部，以此达到扩口目的。例如专利号CN201921130203.7公开了一种塑料管材扩口装置。此装置通过加热塑料管材，待管材软化后将扩张体塞入管材端部，由于扩张体外径大于管材内径，以此达到塑料管扩口的目的。此种扩口方式由于将扩张体轴向塞入管道中，管材端部会受到一个轴向力，已经软化的管材非常容易受压起褶皱，影响扩口质量；而且这种扩口方式仅能适用于塑料实壁管，无法应用于钢丝增强等非金属复合管。因为复合管一般分为内层、增强层和外层，此种扩口方式非常容易让内层受挤压而内缩损坏管材，而增强层和外层达不到扩口的目的。并且现有的扩口机一般重量较大，不便施工现场以及抢修使用。
发明内容

通过采用上述技术，与现有技术相比，本发明的有益效果如下：
1)本发明装置采用新型扩口方式，通过大齿轮上的弧形槽带动扩口模具径向的移动，并且采用伺服电机驱动大齿轮，以此控制大齿轮的正转反转，即实现了自动化调节扩口模具的内缩和扩口，此扩口方式是由八个扩口模具径向外扩来实现管材的扩口，因此避免了现有扩口方式导致复合管扩口时内层被挤料而损坏管材；
