摘要
Abstract
Cutter is an important part of steel bar cutting machine.The elastic-plastic deformation and fracture mechanism of steel bar are analyzed during cutting.Cutting formula is listed.Cutting model is found based on a factory's steel bar cutting machine.Dynamics simulation of cutting process is done, and parameters influence on cutting force are analyzed, and the reliability of simulation results is verified by experiments.A series of simulation results are obtained.Cutting force is decreasing first and then increasing with the increase of side gap between upper and lower cutter, and cutting force is the smallest when the distance is 0.1mm.Cutting force is decreasing with the cutting edge angle increase of upper cutter.The results provides theoretical basis for the cutting machine design and installation.关键词
