Mechanism Design and Dynamic Analysis of Hybrid Cam-linkage Mechanical Press

摘要

This paper proposes a new structure of hybrid cam-linkage mechanical press. First of all, the design process is introduced and positive movement simulation is done separately for hybrid cam-linkage mechanism and hybrid seven-bar mechanism in Pro/Mechanism. Through comparing the curves of slider's output displacement, velocity and acceleration, it comes to the conclusion that the slider of hybrid cam-linkage mechanical press has better output motion characteristics. Then power and torque distribution of servo motor and general motor of the hybrid cam-linkage mechanical press is studied in ADAMS based on the simulation results. At last, torque of general motor and servo motor in practical work is analyzed by taking cold extrusion press as an example.
