摘要:

 针对导管扩口成形过程中因扩口伸出量的不确定导致的导管轴向成形精准度差的问题,基于导管扩口成形的具体参数要求,采用ABAQUS对Φ22 mm×1 mm的LF2M铝合金导管的扩口成形过程进行有限元仿真分析,得到成形过程中旋压棒的载荷-行程变化规律以及旋压棒、导管扩口端、平管嘴之间的接触变化规律,在此基础上研究了不同伸出量的旋压棒端面距离-行程和旋压棒最大外径-行程的变化规律。研究结果表明:不同伸出量在特定的旋压棒行程下成形的扩口端均能满足成形参数要求,但伸出量的可选范围大,严重影响导管轴向成形精度,需对伸出量进行精确控制。基于扩口成形变化规律确定参考伸出量,并进行相应的工艺试验研究,为标准伸出量的确定提供了理论依据。

 

 For the problem of poor accuracy for catheter axial forming caused by the uncertainty of flaring extension amount during the flaring process of catheter, based on the specific parameters requirements of catheter flaring, the flaring process of LF2M   aluminum alloy catheter with Φ22 mm×1 mm was finite element simulated and analyzed by ABAQUS, and the load-stroke variation law of spinning rod and the contact variation laws between the spinning rod, the flared end of catheter and the flat nozzle were obtained during the forming process. Then, on this basis, the variation laws of end distance-stroke for spinning rod and the maximum outside diameter-stroke for spinning rod under different extension amounts were studied. The results show that the different flared ends formed with the stroke of a specific spinning rod meet the forming parameters requirements under different extension amounts, but the optional range of extension amount is large, which seriously affects the axial forming precision of catheter and requires precise control of extension amount. Based on the variation law of flaring, the reference extension amount is determined, and the corresponding process experiment research is carried out to provide a theoretical basis for the determination of standard extension amount.
