螺旋压力机是一种应用十分广泛的锻压设备,它具有结构简单、操作方便、便于调整、易于维护等优点。特别是近年来随着航空工业、机械工业的发展,又不断得到了改进,出现了液压和电机直接驱动的螺旋压力机。压力机的吨位已由几十吨发展到万吨以上。螺旋压力机的发展引起了模锻工艺特别是精锻技术的飞速发展,也促进了航空工业技术的发展。一、螺旋压力机的发展及使用概况从一八七七年出现螺旋压力机到本世纪廿年代,其驱动形式一直沿袭传统的摩擦驱动形
Screw press is a widely used forging equipment, it has the advantages of simple structure, easy operation, easy to adjust, easy to maintain and so on. Especially in recent years, with the aviation industry, the development of machinery industry, has been continuously improved, there have been hydraulic and motor direct drive screw press. Press tonnage has been developed from tens of tons to more than 10,000 tons. The development of screw press caused the rapid development of forging technology, especially forging technology, and also promoted the development of aviation industry technology. First, the development and use of screw press Overview From the appearance of screw presses in 1877 to the 20th century, the driving style has been followed by the traditional friction-driven
