目前,用高合金材料制造大型飞机壁板有两种方法:即在压力达4 5000吨的大型模锻液压机上模锻和按照予拉成型的板料进行机械加工(拉伸可显著减少进一步切削加工时壁板的畸变)。下面叙述具有如下工艺特性的3600/5400吨压力的拉伸矫正液压机(图1)。被加工板料的尺寸被切割板料的长度,米:最大15.24 At present, there are two ways to manufacture large aircraft wallboards from high-alloy materials: swaging on large forging hydraulic presses up to 45,000 tons and machining on pre-formed sheets (stretching can significantly reduce further cutting Processing of the wall distortion). The following describes a 3600/5400 tonne tension correction hydraulic press with the following process characteristics (Figure 1). The size of the sheet to be processed The length of the sheet to be cut, m: up to 15.24
