摘　　要：针对双盘拉丝机换盘速度慢、效率低的问题,对新型自动换盘装置和工字轮进行了结构和换盘方案的设计。从理论上分析了自动换盘装置的工作原理和流程;通过UG对自动换盘装置和工字轮进行了三维建模,运用ANSYS软件对工字轮和自动换盘装置的结构进行了静力学分析,得出了自动换盘装置和工字轮在实际工作时的应力应变云图;通过动力学仿真分析,设置了相关仿真参数,获得了自动换盘装置的速度、加速度、位移变化曲线。研究结果表明:新型自动换盘举升装置两支点中间变形量最大,受力呈对称分布;钢丝绳与工字轮接触产生的应力变形较小,在合理变形之内;从量化后得到的运动速度、位移曲线规律,验证了运动平稳性和机构设计的合理性。Aiming at the problem of slow changing speed and low efficiency of double wire drawing machine,the structure and changing scheme of new automatic disk changing device and I-wheel were designed.The working principle and flow of the automatic disk changing were analyzed theoretically.The 3D model of the automatic plate changing and the I-wheel was carried out by UG,and the statics analysis of the structure of the I-wheel and the automatic plate changing were carried out by using ANSYS software,and the stress-strain cloud diagram of the automatic disk changing and the I-wheel in actual work were obtained.Through dynamic simulation analysis,relevant simulation parameters were set to obtain the curve of the velocity,acceleration and displacement of the automatic plate changing.The results indicate that the deformation of the two fulcrum of the new type automatic disk changing lifting device is the largest and the stress distribution is symmetrical.The stress deformation caused by the contact between the wire rope and the I-wheel is small and within the reasonable deformation.The motion velocity and displacement carves obtained after quantization verify the motion stability and the rationality of mechanism design.
