摘要
为解决现有织造矿用输送带带芯织物的单剑杆织机织造效率低、单钩针锁边效果差等问题,为多剑杆织机设计新型锁边机构及五钩针纬纱圈嵌套互锁的新型锁边工艺,锁边机构中送纱叉与送纬剑及布边处钩针有交接配合,为保证交接过程的可靠性,要求送纱叉的最大变形不得超过0.5 mm。利用ANSYS Workbench对送纱叉的刚度及强度进行分析,基于响应面法以送纱叉的最大变形为优化目标,对送纱叉的结构参数进行优化设计,基于六西格玛分析法对送纱叉进行可靠性分析,最后进行实验对比。结果表明:与原方案对比,优化方案最大变形减小11.2%,最大应力减小7.8%,且送纱叉最大变形小于0.5 mm的可靠度达到96.1%。
In order to solve the problems of low weaving efficiency and poor single crochet selvage effect of single rapier loom used for weaving mine conveyor belt core fabric,a new edge locking mechanism for multi rapier loom and a new edge locking process with five crochet weft loops nested and interlocked were designed.In the edge locking mechanism,the yarn feeding fork was matched with the weft feeding sword and the crochet at the cloth edge.In order to ensure the reliability of the handover process,the maximum deformation of the yarn feeding fork shall not exceed 0.5 mm.The stiffness and strength of the yarn feeding fork were analyzed by ANSYS Workbench.Based on the response surface method,the maximum deformation of the yarn feeding fork was taken as the optimization objective to optimize the structural parameters of the fork.The reliability of the yarn feeding fork was analyzed based on six sigma analysis method.Finally,the experimental comparison was made.The results show that:Compared with the original scheme,the maximum deformation and maximum stress of the optimized scheme are reduced by 11.2%and 7.8%,respectively,and the reliability of the maximum deformation of the yarn feeding fork less than 0.5 mm reaches 96.1%.
