摘要
剪板机结构力学性能对剪切精度具有重要影响。以6×3200型数控闸式剪板机为对象,基于数值模拟方法对上刀架进行了静力学分析和瞬态动力学分析,得到了剪切过程中的最大等效应力与最大变形;对机架进行了模态分析,给出了剪板机系统可能发生共振的固有频率和相应振型;基于分析结果对闸式剪板机结构进行了优化。
The mechanical properties of shearing machine have important influence on the shearing accuracy.Based on the numerical simulation method,the static analysis and transient dynamic analysis of the upper tool holder are carried out for the 6×3200 numerical control gate shear machine.The maximum equivalent stress and maximum deformation in the shearing process are obtained.The modal analysis of the frame is carried out to obtain the natural frequency and corresponding vibration mode of the shearing machine.Based on the analysis results,the structure of the brake shearing machine is optimized.
