目前在我国重工业系统中,模锻水压机最大锻压能力,远不能满足国防工业的需要。五十年代,美苏两国己相继拥有五万吨与七万吨大型模锻水压机。为了赶超世界先进水平,加速我国国防工业的现代化,必须自行设计制造五万吨水压机。设计中,将水压机“三梁四柱”全部改革为钢筋混凝土结构,其中特别是“动梁”采用予应力钢筋混凝土构件,在世界上也属首次。由於动梁采用了钢筋混凝土构件后体积变得庞大,原型动梁长13.5米,高6.0米,
At present in China’s heavy industry system, forging hydraulic press maximum forging capacity far can not meet the needs of national defense industry. In the 1950s, the United States and the Soviet Union have successively owned 50,000 tons and 70,000 tons of large forging hydraulic presses. In order to catch up with the advanced world level and accelerate the modernization of China’s defense industry, it is necessary to design and manufacture a hydraulic press of 50,000 tons. In the design, the hydraulic press “three beams and four columns” all the reform for the reinforced concrete structure, in particular, “moving beam” prestressed concrete components, also in the world for the first time. Due to the moving beam with reinforced concrete members became large, the prototype beam length 13.5 meters, 6.0 meters high,
