Design And Simulation Research On Transmission System And Stripping Mechanism Of Forging Press

The slender rod produced by casting and turning can not meet the modern industrial requirements for high quality and intensity, so more and more attention are focused on the high quality slender rod production. There is an urgent market needing for slender rod's multi-stage cold forming automatic forging machine. As important part, the transmission and stripping mechanism decide the operating performance and the economy, so it is valuable to do the transmission's dynamics simulation and optimization design, and the ejecting mechanism's finite element analysis.To meet the specific requirements, through the moving and force analysis we identify the main factors that affect transmission dynamics. Then we use ADAMS to do the transmission's core component's statics simulation of optimal design. The results help us to identify the main force direction and location of the machine. After this we acquire the best solution of the transmission to meet the design and economic requirements. According to the most important part of the stripping mechanism - putt and bar, we use ANSYS to do their stability research. Through the stress distribution and yield state, we obtain the best design. According to the specific working environment of the bar, we do the finite element analysis of the thermal - stress coupled field to see whether the bar have deformation under the thermal stress.The comparison of practice and simulation results proved that the model can well reflect the actual working condition. We provide a more reasonable, more reliable and more efficient way to the design of BP-440EL cold forming and forging machine with multiple working positions.
