现代自由锻造液压机关键部件设计特点

Design features of modern open die forging press body

对现代液压机的压机框架、活动横梁及导向装置、主工作缸、回程装置、上砧锁紧装置、移动工作台等本体部件的先进设计特点进行了介绍,并就一些部件的设计要点及目前常见的设计方式进行了简单分析。在压机本体设计中,先进的结构设计包括:预应力框架结构、可调间隙斜键平面导向结构、双球面中间杆式柱塞连接结构、上砧快换锁紧装置等。

The advanced designing work of group press frame,moving crossbeam and guiding device,main working cylinder,returning device,upper die clamping device and table shifting device of modern hydraulic press body were introduced,and the main design points and the most common design approaches of some components were analyzed simply.The advanced design features of the press body include the pre-stressed frame structure,the adjustable clearance flat guidance with wedge,the plunger joint structure including two ball lenses and one swiveling pin,fast-changing upper die clamping device and so on.
