Study on Clamping Force of Forging Manipulator Gripping Mechanism Based on Virtual Prototype Technology

The multi-body dynamic model and finite element model of gripping mechanism were built by Pro-E、Mechanism/Pro、ADAMS and ANSYS software based on virtual prototype technology.The relationship between gripping force F0 and forging dip angle was researched under the condition of friction,and the strength of key parts with different clamping force F0 were analyzed.The results showed that the optimal clamping force of gripping mechanism discussed in the paper is 240T~250T for rated load by comprehensive consideration of forging dip angle  and safety factor n of key parts.The results can provide certain theoretical significance for improving the reliability of gripping mechanism and further realizing the flexible control of gripping forging.
