Description

一种碳纤维开口检具框架及其制备方法
技术领域
本发明涉及检具的加工制造技术领域，特别是涉及一种碳纤维开口检具框架及其制备方法。
背景技术
传统的开口检具的制备工艺是采用缠绕成型在连接组装的方式，即先将浸过树脂胶液的连续纤维按照一定的规律缠绕在芯模上，固化，脱模得到纤维管，然后将这些纤维管按照开口检具的构造搭接组合。其中搭接方式是将糊状树脂覆盖在管与管的接触处，待糊状树脂半固化后，再将浸过树脂胶液的连续纤维按照一定的规律缠绕在树脂上，将树脂全部覆盖。这种方式存在如下技术问题：1、工艺步骤多，加工周期长，效率低；2、不能实现一体化成型，而且各个部件连接组装，影响检具的整体性能及材料性能的发挥；3、无论是采用人工连接缠绕还是机器人协助，都会存在连接误差，特别是不在同一水平面，具有一定角度或弧度，这种连接错位，不仅影响检具的整体外观，同时影响其使用，易造成受力不均变形或断裂。
发明内容
本发明的目的在于克服上述现有技术的缺陷，提供一种有效提高连接准确性，简化工艺步骤，缩短生产周期，提高工作效率的碳纤维开口检具框架；
本发明的另一是提供上述碳纤维开口检具框架的制备方法。
为实现本发明的目的所采取的技术方案为：
一种碳纤维开口检具框架，其特征在于其是由若干个碳纤维管和碳纤维接头按照开口检具的结构形式组装而成。
所述碳纤维接头为多端头结构，所述端头外径与碳纤维管的内径相同，且长度为5-20mm。
上述碳纤维开口检具框架的制备方法，其特征在于其工艺步骤包括：
碳纤维管的成型：用碳纤维预浸布包裹钢管芯材，之后在外层卷OPP膜，固化、冷却后抽取钢管芯材，脱OPP膜，得到碳纤维管；
碳纤维接头成型：设计加工所需端头数的接头成型模具，将碳纤维布分别铺层于上、下模腔内，将泡沫芯夹于两模具间，合模，锁模，抽真空，注胶口注胶，固化，脱模，得到多端头接头；
碳纤维开口检具组装：按照开口检具的构造进行组装。
所述碳纤维管的成型中的固化是在150-155℃温度条件下加热固化115-130min。
所述碳纤维接头成型中的固化是在室温下固化，或者40-50℃温度条件下固化100-150min。
本发明的碳纤维开口检具框架是采用成型好的碳纤维管与成型好的碳纤维接头按照开口检具的结构形式组装而成，该方法避免了传统工艺中采用糊状树脂粘接纤维丝缠绕的复杂工艺，从而提高了连接的准确性，简化工艺步骤，缩短了生产周期，提高了工作效率；同时所用的碳纤维接头采用模具成型技术，可实现一体化成型，它与纤维管的连接方式为内扣连接，既可增加接头与碳纤维管的咬合强度和稳定性，又可改善连接为的外观问题。
附图说明
图1为一种类型开口检具的结构示意简图；
图2为当相邻接点的距离为20-70cm时，碳纤维接头与碳纤维管采用一体化成型技术的图；
图3为接头的结构示意图。
具体实施方式
下面结合实例对本发明的具体实施方式作详细说明。应该理解的是，实例是用于说明本发明而不是对本发明的限制。本发明的范围与核心内容依据权利要求书加以确定。
本发明的碳纤维开口检具框架是由若干个碳纤维管和若干个碳纤维接头按照开口检具的结构形式组装而成，其中碳纤维接头为多端头结构形式，其中间部位的外径可与碳纤维管外径相同，端头外径与碳纤维管的内径相同，且长度为5-20mm，这样增加接头可增加接头与碳纤维管的咬合强度和稳定性，同时改善连接处的外观问题。
本发明的碳纤维开口检具框架的制备方法为：
1、碳纤维管的成型：选择满足直径要求的钢管芯材，裁减所需尺寸的碳纤维预浸布；用碳纤维预浸布包裹钢管芯材，一层一层卷压成型，再在外层卷多层OPP膜；之后在150-155℃温度条件下加热固化115-130min，冷却，抽取钢管芯材，脱OPP膜，得到碳纤维管。
2、碳纤维接头成型：采用模具成型，多端头接头一体化成型技术。
首先准备接头成型模具，CNC加工，得到需要端头数的接头模具，模具分为上、下模。然后对模具进行打蜡等预处理步骤，裁减所需尺寸大小的碳纤维布，和泡沫芯材。 之后将碳纤维布分别铺层于上、下模腔内，将泡沫芯夹于两模具间，合模，锁模，抽真空（1-2个真空度），注胶口注胶，固化（室温固化，或者40-50℃温度条件下固化100-150min），脱模，得到多端头接头。该多端头接头为双层结构，外层为纤维复合材料，内层为泡沫。
3、碳纤维开口检具组装：按照开口检具的构造进行组装。组装时，将多端头接头插入到碳纤维管中粘接。
