摘　　要：随着新能源技术的不断发展,高压气瓶的生产需求日益增长,纤维缠绕成型技术则是生产高压气瓶过程中的一种关键技术.目前纤维缠绕技术在国内发展中依然面临着许多严峻的挑战,如由于有芯纱团自身原因导致纱线缠绕张力控制不均以及缠绕手腕运作时所需的驱动电机过多导致成本过高等问题.故该文以数控龙门式缠绕机为研究对象,设计了一种缠绕手腕装置,然后对纤维缠绕工艺进行优化,提出了一种往复式数控有芯纱团张力控制方法,并通过实验对龙门缠绕机器的性能进行验证.实验表明,经过改进后的缠绕机缠绕速度提升至150 m·min^(-1),缠绕小车运行速度提升至125 m·min^(-1).With the continuous development of new energy technology,the production demand of high-pressure gas cylinders is increasing,and fiber winding forming technology is a key technology in the production of high-pressure gas cylinders.At present,there are many severe challenges of the fiber winding technology in the domestic development,such as the uneven tension control of yarn winding caused by the core yarn itself and the high cost caused by too many driving motors needed in the winding wrist operation.Therefore,the CNC gantry winding machine is taken as the research object,a wrist winding device is designed,and the fiber winding process is optimized.A reciprocating CNC core yarn tension control method is proposed.The performance of the gantry winding machine is verified through experiment.The experimental results show that the winding speed of the improved winding machine is increased to 150 m·min^(-1)and the running speed of the winding trolley is improved to 125 m·min^(-1).
