摘　　要：旨在为全自动三缸卧式液压榨油机的弹簧复位机构的设计和应用提供参考,分析了全自动三缸卧式液压榨油机的结构和工作原理,利用ADAMS软件通过模型简化、约束设置、仿真力添加以及驱动设置建立仿真模型,根据主油缸推进压榨、主油缸复位、副油缸推进卸饼、副油缸复位4个工作步骤对弹簧刚度和预紧力进行仿真设计,并根据仿真结果进行综合设计和试验验证。仿真结果显示:弹簧设计刚度为32.5N/mm,预紧力为100N;为消除制造及装配误差,实际制造设计的弹簧刚度为32.69N/mm,预紧力为163.45N。验证试验结果显示:运行过程中压榨环与压盘体最大轴向缝隙仅为2.54mm,无漏料现象,且所有运动部件均能复位到初始位置,运行平稳可靠。综上,利用ADAMS软件能够准确表达全自动三缸卧式液压榨油机压榨机构运动过程,对弹簧复位机构的优化设计结果可靠。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.
