摘要：

针对上压式双柱自由锻造液压机的结构特性和工作状态，分析了工作缸与活动梁连接球铰副的工作条件，阐述了横向偏心锻造与纵向偏心锻造的成形过程，分析了偏载工况下柱塞与缸体的接触状态。结合上压式双柱自由锻造液压机工作缸与活动梁的典型连接形式，研究了工作缸柱塞与活动梁连接形式的工作机理，明确了工作缸柱塞与活动梁的不同连接形式对液压机的影响，确定了适合大型上压式双柱自由锻造液压机的结构形式，研究了合理控制液压机偏心锻造的条件，制定了液压机的偏载控制策略，提出了液压机最大允许锻造偏心距的确定思路，为大型上压式双柱自由锻造液压机的结构设计和安全使用提供了理论依据。

In view of the structural characteristics and working conditions for upward pressure double-column free forging hydraulic press, the working conditions of ball hinge pair connecting working cylinder and movable beam were analyzed, the forming processes of transverse eccentric forging and longitudinal eccentric forging were explained, and the contact state between plunger and cylinder body under the condition of eccentric load was analyzed. Then, combined with the typical connection form of the working cylinder and the movable beam for the upward pressure double-column free forging hydraulic press, the working mechanism of the connection form for the the working cylinder plunger and the movable beam was studied, and the influences of different connection forms for the working cylinder plunger and the movable beam on the hydraulic press were clarified. Furthermore, the structure form suitable for the large-scale upward pressure double-column free forging hydraulic press was determined, and the conditions for the reasonable control of eccentric forging for hydraulic press were studied. Finally, the eccentric load control strategy of hydraulic press was formulated, and the determination thoughts of the maximum allowable forging eccentricity for hydraulic press was proposed, which provided a theoretical basis for the structural design and safe use of the large-scale upward pressure double-column free forging hydraulic press.
