摘要：

为满足大型精密模锻件的成形工艺需要，须在大型模锻液压机上装备纠偏装置或调平系统，使活动横梁在偏心载荷下达到一定的水平精度。结合一台具有模锻功能的350 MN多向双动挤压液压机研制、创新液压机结构和控制系统设计，从技术可靠、简单、适用和低成本角度，探讨了活动横梁基于对偏心载荷响应的纠偏调平策略。将回程缸与主缸一起构成一个纠偏力自适应调平系统。按偏心力矩产生的方位，使其中的1个或2个回程缸升压、使相对应的主缸旁路卸压，组成闭环调节回路，可使活动横梁的动态水平度控制在允许范围内，系统简单可靠、装机功率低、运行效率高。

In order to meet the requirements of forming process for the large precision die forgings, it is necessary to equip the correction device or the leveling system in the large die forging hydraulic press, so that the movable beam can achieve a certain level accuracy under the eccentric load. Combined with a 350 MN multi-directional double-action extrusion hydraulic press with die forging function, the hydraulic press structure and the control system design were studied and innovated, and the correction and leveling strategy of movable beam based on the response to eccentric load was discussed by the perspective of reliability, simplicity, applicability and low cost, Furthermore, the return cylinders and the main cylinders together constituted a corrective force self-adaption leveling system. According to the position generated by the eccentric moment, the closed-loop adjustment loop was formed by boosting one or two of return cylinder and depressurizing the corresponding main cylinder bypass, and the dynamic levelness of movable beam was controlled within the allowable range. Thus, the system is simple and reliable with low installed power and high operating efficiency.
