横梁是摩擦压力机的关键部件,它与机身连接一体。横梁镶嵌丝母的中心孔顶部顶裂,丝母也断裂。横梁断裂的原因:由于丝杆和丝母的间隙过大,使工作中每次都承受反作用力的疲劳冲击;同时还造成丝母分开受力受顶力,而受拉力,丝母总长度为450mm,总受力为180t。使以上的一段断裂,而150mm长的一段螺纹也被拉断。另外横梁本身的材料是铸铁,它不能承受冲击
Beam is a key component of the friction press, which is connected with the fuselage. The top of the center hole of the beam inlaid with the nut crack, the nut is also broken. Beam breakage reasons: As the screw and nut gap is too large, so that work each time to withstand the reaction of the fatigue impact; also caused by nut separate force by the top force, and by tension, the total length of nut 450mm, the total force of 180t. The above section was broken, while a length of 150 mm was also broken off. In addition the beam itself is made of cast iron, it can not withstand the impact
