我国锻造操作机已进入了系列标准化设计,专业制造厂生产,大力发展液压传动新型操作机的新阶段。但由于我国操作机系列化设计、制造还在初始阶段,前几年又受到“四人帮”的干扰与破坏,故进展速度不快。在操作机力学的理论计算上,在液压系统的设计上都不完善,第一代的液压传动系列产品操作机还存在一些缺陷。这些缺陷从设计的角度上来看有不少是反映了设计理论的不确切和设计考虑的问题不完全。近年来,哈尔滨工业大学、上海交通大学结合设计、制造单位对操作机的理论计算做了一些研究工作,这些工作的成果对 China forging operation machine has entered a series of standardized design, professional manufacturer, vigorously develop the new stage of hydraulic transmission of new operating machine. However, due to the series design and manufacture of manipulators in our country, the initial stage of manufacture was still disturbed and destroyed by the “Gang of Four” a few years ago, so the pace of progress was not fast. In theoretical calculation of mechanics of mechanics, the design of hydraulic system is not perfect, the first generation of hydraulic transmission products operating machine there are still some shortcomings. Many of these shortcomings, from a design point of view, reflect incompleteness of design theory and design considerations. In recent years, Harbin Institute of Technology, Shanghai Jiaotong University, combined with design, manufacturing unit of the theoretical calculation of the manipulator to do some research work, the results of these efforts
