摘　　要：针对现有异型针刺成型装备专用性强,难以适应小批量、多品种回转结构复合材料预制体的针刺成型要求的问题,提出一种复合材料回转预制体柔性针刺成型系统。根据回转预制体的针刺成型特性,提出采用四轴联动的针刺机运动机构和气动针刺头构型,基于可编程控制器(PLC)和触摸屏,设计了柔性针刺成型控制系统,并进行实验验证。实验结果表明:针刺实验针迹和模拟针迹高度一致,证明了四轴柔性针刺系统的可行性,该系统可以实现回转预制体的针刺成型;通过采用单气缸新型针刺头,针刺频率达到110次/min,针刺效率比现有的双气缸针刺头提高了1倍。Existing special shaped needle-punching forming equipment is difficult to be adapted to the needle-punching forming requirements of small-volume and multi-variable rotary structure composite preforms.To address on this problem,a needle-punching forming system for flexible rotary preforms was proposed.According to the needle-punching forming characteristics of the rotary preform,a four-axis linkage needle-punching moving mechanism and a pneumatic needle-punching head configuration were used,and a needle forming system was constructed using the programmable logic controller(PLC)and the touch screen,which was verified by experiments.The research results show that the needle traces of the needle punching experiment and the simulated needle traces are highly consistent,proving the feasibility of the four-axis needle punching system.The needle punching frequency reaches 110 times per minute,and the needle punching efficiency is doubled compared with the existing double-cylinder needle punching head.
