摘要
Structural sufficiency of an industrial hydraulic shear to safeguard quality of the cuts is investigated by 3D finite element modeling of base and guillotine of the machine tool.Shearing forces are calculated analytically and rams as well as guillotine hinges are represented by calculated actions and reactions accordingly.Reinforcement with ribs and structural sheet thickening are investigated in alternative models, the ribs giving a reduction of maximum blade gap by a factor of 3. Torsional resistance of the guillotine cannot be sufficiently increased pointing to a control solution in the hydraulic circuit.
