通过对大型模锻液压机的液体工作压力选择、工作缸数量和布置型式的研究分析,并结合国内外400 MN以上大型模锻液压机的液体压力和缸布置型式、工作缸的数量及3种主要布置型式(三缸排列、九缸排列、五缸排列)与机架结构尺寸和液压系统之间的关系,确定了我国自主设计制造的800 MN大型模锻液压机的液体工作压力为63 MPa,工作缸数量和布置采用五缸梅花形排列型式。
Based on the analysis of hydraulic working pressure, number of working cylinders and arrangement pattern of large forging hydraulic press, combined with the liquid pressure and cylinder arrangement type of large forging hydraulic press above 400 MN at home and abroad, the number of working cylinders and three main layouts Type (three-cylinder arrangement, nine-cylinder arrangement, five-cylinder arrangement) and the size of the rack structure and the relationship between the hydraulic system to determine China’s independently designed 800 MN large forging hydraulic machine working pressure of 63 MPa, the working cylinder The number and layout of the five-cylinder arrangement of the plum-shaped.
