以TLJ400连续挤压机为原型,基于Deform-3D有限元模拟软件,通过建立铜镁合金连续挤压数值模拟模型,获得了不同挤压轮转速下金属连续挤压成型过程中的温度分布、等效应力分布以及挤压轮扭矩的分布情况。结果表明,随着挤压轮转速的提升,连续挤压成型过程中金属的变形温度不断升高,等效应力值和挤压轮扭矩不断下降。 Based on the Deform-3D finite element simulation software and the TLJ400 continuous extrusion machine as the prototype, the numerical simulation model of continuous extrusion of copper-magnesium alloy was established to obtain the temperature distribution during continuous extrusion of metal under different extrusion wheel speeds, etc. The distribution of the effective stress and the distribution of the torque of the extrusion wheel. The results show that the deformation temperature of the metal increases continuously with the increase of the rotating speed of the extrusion wheel, and the equivalent stress and the torque of the extrusion wheel decrease continuously.
