摘要
为减少薄铝箔剪切机在高速切削过程中产生的震动,找到影响分切过程中震动产生的主要因素,对碟形刀装置进行ABAQUS有限元仿真分析,通过模拟实际工况,分析加载周期性载荷工况下的应力、应变分布情况。结果表明:在螺栓预紧力的作用下,刀座径向开口处发生变形,尤其碟刀片安装基准面变形明显,最大变形位移超过0.03 mm;在高速切削过程中,碟刀片受到不均匀切削力的周期性变化,导致整体装置震动,降低了分切精度。实验数据验证了仿真结果的正确性。对结构进行优化改进后,已在实际产品中得到应用。
In order to reduce the vibration generated by the thin aluminum foil shearing machine in the high-speed cutting process and find out the main factors affecting the vibration during the slitting process,the ABAQUS finite element simulation analysis on the dish-shaped tool is conducted,with whose actual working results,the distribution of loaded stress and strain is analized.The results show that the radial opening of the tool holder is deformed over 0.03 mm under the application of bolt preloaded,and the base surface of the disc blade displays even greater deformation.During the high-speed cutting process,the disc blade is subjected to periodic changes in uneven cutting force,which causes the vibration of the overall device and reduces the cutting accuracy.Experimental data verify the vadility of the simulation results.After structure optimization,the improved cutter device has been applied in actual products.
