本机床系利用旧有高压蒸汽水泵,配以无缝钢管制成。水压缸二只,装在型钢构架上包括生铁模子搁脚和生铁平台等。当蒸汽工作压力7公斤/公分~2时,二缸共能产生300吨压力,此机制造简单,不需要蓄力器等复杂装置。我厂在压制10吨锅炉汽包封头时,封头直径为1320公厘,钢板厚度20公厘,每只压制连退下的时间 The machine tool uses the old high-pressure steam pump, with seamless steel pipe. Two hydraulic cylinders, mounted on the steel frame, including cast iron mold foot and pig iron platform. When the steam working pressure of 7 kg / cm ~ 2, a total of two cylinders can produce 300 tons of pressure, this machine is simple to create, does not require complex devices such as power storage device. I plant in the suppression of 10 tons of boiler drum head, the head diameter of 1320 mm, the thickness of 20 mm steel plate, each withheld even the time
