【摘要】 螺栓套缠纱是风电叶片生产中的一项重要工艺过程，缠纱工艺的好坏与风电叶片根部的连接稳定性有着十分重要的关系，目前螺栓套缠绕玻璃纱的操作，大多是人工进行，存在缠纱作业效率低、劳动强度大及缠纱质量不稳定的情况。文中围绕螺栓套缠纱的关键工艺步骤进行研究，通过对螺栓套缠纱的技术指标和要求的分析确定，设计了一种螺栓套自动缠纱设备，将设备分为上料推送装置、送纱装置、缠纱装置和收纳装置，实现了自动缠纱中螺栓套夹紧、玻璃纱预紧力控制、连续缠纱和产品收纳这4个关键技术；通过大量试验分析，得到了预紧力在1.96～3.43 N之间，且保证缠纱效率较高的条件下，安装压纱轮数为4～5个、玻璃纱股数为3～4股及缠纱轴转速为160～220 r/min的预紧力控制方案为控制缠纱预紧力的最佳方案。更多还原

【Abstract】 Bolt-sleeve yarn winding is an important technological process in terms of wind-power blade production; the quality of the yarn-winding process has great influence on the stability of wind-power blade root connection. At present, most of bolt-sleeve glass yarn winding is carried out manually, with low efficiency, high labor intensity and unstable quality. In this article, efforts are made to explore the key technological steps of bolt-sleeve yarn winding; a bolt-sleeve automatic yarn-winding equipment is designed by analyzing and confirming the technical indexes and requirements of bolt-sleeve yarn winding. The equipment is divided into feeding-push device, yarn-feeding device, yarn-winding device and storage device. Four key technologies including bolt-sleeve clamping, glass yarn preload control, continuous yarn winding and product storage are realized in automatic yarn winding. Through a large number of test and analysis, it is shown that when the preload force is between 1.96～3.43 N and the high efficiency in yarn winding is guaranteed, there are 4～5 yarn pressing wheels and 3～4 glass yarn strands, and the winding shaft speed is 160～220 r/min, which is optimal to control the preloading force of yarn winding.更多还原
