螺旋压力机,总的来看,有三种传动型式,即摩擦式、电动式和液压式.摩擦压力机早已在汽车、拖拉机、农机和金属制品等工业部门中,用来模锻、精压、校正、弯曲和冲压.据西德一九六○年调查表明,在月产量1000吨以上的锻造工厂中,螺旋压力机仅次于锻锤之后是最普遍采用的设备,占全部机械设备拥有量的12.5%;捷克一九五四年模锻设备拥有量中有51%是螺旋压力机;美国及苏联尽管在大批大量生产中主要采用热模锻压力机,但螺旋压力机也占有相当的比例. 欧洲某些国家在螺旋压力机上模锻汽车阀门、后半轴和发动机曲轴、齿轮以及航空发动机等零件毛坯,如在西德Hasenclever公司生产
Spiral presses, in general, have three types of transmission, friction, electric and hydraulic. Friction presses have long been used in the automotive, tractor, agricultural machinery and metal products sectors such as forging, coining, Calibration, Bending and Stamping. According to the West Germany Survey in 1960, screw presses are the most commonly used equipment after forging hammers in forging plants with a monthly output of more than 1,000 tons, accounting for the total amount of machinery ownership 12.5% of the Czech Republic’s die-forging equipment in 1954. In the United States and the Soviet Union, hot-press forging presses are predominantly used in mass production, but screw presses also occupy a considerable proportion Some European countries forge die for automotive valves, rear axles and engine crankshafts, gears, and aeroengine blanks on screw presses, as produced at Hasenclever, West Germany
