Optimized design and finite element analysis for frame of mouldless cold spinning Machine for vessel end closures

Based on analyzing the forces acting on the frame of the mouldless cold spinning machine for vessel end closures,a frame load-carrying model under static state was created using mainly the analytic software ANSYS and the simulation software SolidWorks.Based on the structural characteristics of the assembled frame,the acting force between the upper beam of the frame and the pre-tightening nut were analyzed and computed.And the loading model was obtained by applying the loads and constraints on the frame of the spinning machine.Then the strength and stiffness of the machine body was calculated,the location of the danger point was determined and topology optimization of the frame was carried out through finite element analysis.After that a specific improvement plan is proposed and the machine body structure is optimized according to the analysis results,which lays a good foundation for the optimized structural design of the whole spinning machine.
