由西安重型机械研究所设计,上海彭浦机器厂制造的LD-120Ⅲ型五辊冷轧管机最近在咸阳石油钢管钢绳厂投入生产。该机是目前国内最大的多辊厚壁精密冷轧管机。该机是在LD-120五辊冷轧管机基础上重新设计的。在重新设计中根据LD-120冷轧管机长管坯长行程的特点,对机头芯棒卡盘、回转送进箱、动平衡机构、气囊离合制动器等多处作了较大改进,并首次使用了计
Designed by Xi’an Heavy Machinery Research Institute, the LD-120Ⅲ five-roll cold rolling mill manufactured by Shanghai Pengpu Machinery Factory was put into production recently in Xianyang Petroleum Pipe Steel Wire Rope Factory. This machine is currently the largest multi-roll thick-walled precision cold rolling machine. The machine is based on the LD-120 five-roll cold rolling machine redesigned. According to the characteristics of LD-120 long tube blank’s long stroke in redesign, great improvements have been made to many aspects such as the head mandrel chuck, rotary feed box, dynamic balance mechanism, airbag clutch brake and so on Used for the first time
