  波状螺杆是最早由美国HPM公司A.Kruder等人提出,后来在美国及其他国家发展起来的一种塑料混合异型螺杆。所谓波状螺杆就是在常规全螺纹螺杆上用一波状段代替全螺纹段,如图1a所示。波状螺杆的特点是两个相邻螺槽的底径相等,但却是偏心的,而且偏心距相等,并与螺杆轴线对称。由于螺槽深度沿轴向呈波浪形周期性地变化,所以预塑时物料受到强挤压和强剪切作用,从而提高塑料挤
出机、注塑机的混合能力。有的波状螺杆主要能提供分布混合,有的波状螺杆既有分布混合能力,也有分散混合能力,波状螺杆被广泛应用于塑料加工工业。

  本文在形体分析的基础上,通过对波状螺杆的分段特征参数化建模,最终实现了各种波状螺杆的参数化装配设计,且模型正确无误。限于篇幅,没有叙述更多种类波状螺杆的参数化建模过程。相同种类的螺杆,其变化大多只是结构尺寸,采用参数化方法建模设计不仅可以节省时间,还便于实现系列化设计和变异设计。本文螺杆零件模型的建立方法,是一个从“零件”到“装配”再到“零件”的过程,能有效解决由于螺杆结构的复杂性所带来的建模困难问题,同时利用SolidWorks强大的黄金伙伴软件可以使螺杆的CAD/CAE/CAM技术应用更加方便。
