| Abstract: |
| In order to provide reference for the design and application of spring return mechanism for fully automatic three cylinder horizontal hydraulic press, the structure and working principle of fully automatic three cylinder horizontal hydraulic press were analyzed, and a simulation model was established using ADAMS software through model simplification, constraint setting, simulation force addition, and drive setting. The spring stiffness and preload force were simulated and designed based on four working steps: main cylinder pushing press, main cylinder reset, auxiliary cylinder pushing cake unloading, and auxiliary cylinder reset. Comprehensive design and experimental verification were carried out based on the simulation results. The simulation results showed that the designed stiffness of the spring was 32.5 N/mm, and the preload force was 100 N; to eliminate manufacturing and assembly errors, the actual manufacturing design had a spring stiffness of 32.69 N/mm and a preload force of 163.45 N. The verification test results showed that the maximum axial gap between the pressing ring and the pressure plate body during operation was only 2.54 mm, with no material leakage, and all moving parts could be reset to their initial positions, ensuring smooth and reliable operation. In summary, the use of ADAMS software can accurately express the motion process of the press mechanism of a fully automatic three cylinder horizontal hydraulic press and the optimization design results of the spring reset mechanism are reliable. |
