Abstract: 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.
