一、概述随着锻压工艺的发展,古老的螺旋压力机在驱动方式上有了重大的改变,特别是五十年代以后,液压驱动和电机驱动的螺旋压力机有了惊人的发展。西德 Hasenclever 公司为奥地利设计制造的 HSPRZ1150型大型螺旋压力机,公称压力达12500吨,将于1982年装配完毕。西德 Weingarten 公司在本世纪七十年代就为美国设计制造了公称压力为8000吨的大型电动螺旋压力机;目前还正在为英、法两国装配公称压力为8000吨的螺旋压力机;并拟生产
First, an overview With the development of forging process, the ancient screw press has a significant change in the driving mode, especially after the fifties, hydraulic drive and motor-driven screw press has astonishing development. West Germany Hasenclever company designed and manufactured in Austria HSPRZ1150 large screw presses, nominal pressure of 12,500 tons, will be completed in 1982 assembly. West Germany Weingarten Company in the seventies of this century for the United States designed and manufactured a nominal pressure of 8,000 tons of large electric screw presses; is currently being installed for Britain and France, the nominal pressure of 8,000 tons of screw presses; produce
