设计了数控冲压中心直线型模具库系统,并采用Creo 3.0进行了三维建模,分析了数控冲压中心模具库系统的工作原理,用ANSYS Workbench对模具库系统进行了模态分析,得出了前六阶固有频率和振型,并通过实验验证了建模和分析的正确性。分析结果表明,模具库系统的工作频率低于其固有频率范围,故模具库系统不会发生共振。通过对模具库系统进行瞬态动力学分析,得出最大等效应力在t=0.16 s时达到最大值8.3024 MPa,远小于材料的屈服强度355 MPa,因此,模具库系统的设计是合理的,能够满足受冲击载荷作用时的强度要求。
The CNC punch center linear mold library system was designed and the 3D modeling was done by using Creo 3.0. The working principle of CNC punch center mold library system was analyzed. The mold library system was analyzed by ANSYS Workbench. Sixth-order natural frequency and mode shape, and verify the correctness of modeling and analysis by experiments. The analysis results show that the operating frequency of the mold library system is lower than its natural frequency range, so the mold library system will not resonate. Through the transient dynamic analysis of the mold base system, the maximum equivalent stress reached the maximum of 8.3024 MPa at t = 0.16 s, which is much smaller than the yield strength of the material of 355 MPa. Therefore, the design of the mold base system is reasonable, To meet the impact of the role of load when the intensity requirements.
