Soundless pressing cnc makes the punch , driven by hydraulic pressure , shift during the work cycles to achieve the process of soundless press , that is to say , the punch die gets close to the material fast , and it penetrates the material till the material breaks , then the punch springs back quickly to reduce noises and vibration and assure the high production efficiency at the same time 静音冲压cnc控制液压驱动的冲头在工作循环中变速,实现静音冲压,即凸模快速接近材料,接着缓慢进入材料直到断裂完成,然后冲头快速返回,以减少噪音和震动,同时保证了较高的生产效率
Based on the constitutive relationship coupled microstructure evolution , 3d - fe simulation of isothermal forging process of tc6 titanium alloy disc is performed dealing with different deformation temperature , punch velocity and shear factor of friction , effect of process parameters on equivalent strain , equivalent stress and grain size is calculated , and load - displacement curve is calculated 本文基于微观组织演变的本构关系模型，对不同变形温度、凸模速度和摩擦条件下钛合金盘的等温锻造过程进行了三维数值模拟，研究了变形工艺参数对等效应变、等效应力和晶粒尺寸的影响，计算了各变形条件下的位移?载荷曲线。
