一种纤维缠绕机自动挂纱夹持机构的设计与验证
|
摘要
针对目前纤维缠绕作业流程中的人工挂剪纱现象,设计了一种应用于纤维缠绕机的自动挂纱机构,并对其中的自动夹持机构这一关键部位进行了实验。采用工业生产中使用的玻璃纤维和碳纤维预浸带作为实验材料,分别在干纱和浸胶状态下测试了机构对纱线的夹持效果,分析了不同夹持力下机构对纱线滑动临界拉力的关系,并对干纱和浸胶状态下机构的夹持效果进行了对比。实验测试结果基本满足了挂纱作业中对纤维夹持力的需求,验证了机构方案的可行性,为挂纱机构的完善和改进提供了参考。
In view of the artificial hanging shear yarn phenomenon in the current filament winding process,an automatic yarn hanging mechanism applied to the filament winding machine is designed,and the key parts of the automatic clamping mechanism are tested. Glass fiber and carbon fiber prepreg belt used in industrial production were used as experimental materials. The effect of mechanism on yarn clamping was tested under dry yarn and soaking state respectively. The relationship between yarn sliding tensile force under different clamping forces was analyzed,and the clamping effect of the mechanism under dry yarn and soaking condition was compared. The experimental test results basically meet the demand of the fiber clamping force in the mechanism,which proves the feasibility of the mechanism scheme,and provides a reference for the improvement of the yarn hanging mechanism.
