Description

螺旋缠绕型材高速挤出机定径装置
技术领域
本实用新型属于管道修复技术领域，特别是一种螺旋缠绕型材高速挤出机定径装置。 
背景技术
目前，我国地下排水管道年久失修的状况十分普遍，由于地下排水管道破损而产生污水渗漏现象，严重污染了地下水资源，并造成局部地下水土流失产生空洞，严重的情况导致地面局部塌陷，给人民的生命带来很大的威胁。现在我国对地下排水管道的修复主要采用传统的开挖方式进行更换，既破坏环境又影响交通。我国采用在排水检查井中缠绕制作出新型塑料管道还处于空白。申请人研发出一种能够螺旋缠绕制成增强型管道的型材，此型材通过自身的锁扣设计螺旋压合形成管道，同时还需要与钢带进行配合，因此，对型材的形状稳定性对缠绕制管的质量尤为重要。 
传统的异型材均采用挤出机通过机头的模具后挤出成型，并通过冷却装置进行定径。但是，现有的异型材挤出机头冷却定径装置，冷却速度慢，达不到缠绕型材的生产要求。 
发明内容
本实用新型的目的在于克服现有技术的不足，提供一种螺旋缠绕型材高速挤出机定径装置，其具有冷却速度快，保证型材形状精确稳定的优点。 
本实用新型解决其技术问题是通过以下技术方案实现的： 
一种螺旋缠绕型材高速挤出机定径装置，包括安装在挤出机上的机头及负压定径装置，其特征在于：所述负压定径装置由型腔、循环水套及负压吸风套构成，在型腔外部设置有循环水套，在循环水套的外部设置有负压吸风套，负压吸风套通过吸风微孔与型腔内连通。 
而且，所述的循环水套为间隔设置在型腔外的3-5个，各循环水套均设置有循环水进口及循环水出口。 
本实用新型的优点和有益效果为： 
本螺旋缠绕型材高速挤出机定径装置，结构设计科学合理，其定径套由循环水套及负压吸风套构成，通过增加一个水冷***，在型材经高速率机头中挤出形状后，在定径套中冷却更加充分，确保型材结构形状不变形，从而提高螺旋缠绕型材上所制的锁扣之间压合间隙均匀，提高螺旋缠绕制得的新管的刚度及严密性。 
附图说明
图1为本实用新型的结构示意图。 
附图标记说明： 
1-负压吸风套、2-循环水进口、3-循环水套、4-吸风微孔、5-螺栓、6-循环水出口、7-型腔、8-型材、9-机头。 
具体实施方式
下面通过具体实施例对本实用新型作进一步详述，以下实施例只是描述性的，不是限定性的，不能以此限定本实用新型的保护范围。 
一种螺旋缠绕型材高速挤出机定径装置，包括安装在挤出机上的机头9及负压定径装置，其中，负压定径装置由型腔7、循环水套3及负压吸风套1构成，型腔是由两半式的模具通过螺栓5固装而成。在型腔外部设置有循环水套，循环水套为间隔设置在型腔外的3-5个，各循环水套均设置有循环水进口2及循环水出口6。循环水套与外部的循环水***连接。在循环水套的外部设置有负压吸风套，负压吸风套通过吸风微孔4与型腔内连通。吸风微孔位于相邻的循环水套之间的位置。 
本实用新型的工作原理为： 
本螺旋缠绕型材高速挤出机定径装置，型材8经挤出机的机头部分挤出后，牵引进入至定径装置的型腔内，在负压作用下吸附于型腔内壁上，同时在循环水套作用下，冷却定型。 
尽管为说明目的公开了本实用新型的实施例和附图，但是本领域的技术人员可以理解：在不脱离本实用新型及所附权利要求的精神和范围内，各种替换、变化和修改都是可能的，因此，本实用新型的范围不局限于实施例和附图所公开的内容。
