近几年来冷挤压技术已成为少无切屑先进工艺之一,这一工艺需要在大吨位压力机上进行。为满足模具型腔冷挤压工艺和压制人造金刚石的需要,上海江湾机械厂设计制造了一台5000吨钢带缠绕机架油压机(封三图②)。主要技术参数: 公称压力 5000吨压机开挡尺寸(纵)1200毫米 (横)900毫米 (高)500毫米工作台面尺寸 800×800毫米叶片泵供油压力 50公斤/厘米_2 增压器供油压力 1000公斤/厘米_2 工作缸最大行程 250毫米工作缸空行程速度 200毫米/分工作缸工作行程速度 0~6.5毫米/分工作缸回程速度 400毫米/分
In recent years, cold extrusion technology has become one of the less advanced technology without chip, this process needs to be carried out in large tonnage presses. In order to meet the cold extrusion die cavity technology and the need to suppress synthetic diamond, Shanghai Jiangwan Machinery Factory designed and manufactured a 5000-ton strip wound hydraulic machine (Figure 3). Main technical parameters: Nominal pressure 5000 tons Press the open block size (vertical) 1200 mm (horizontal) 900 mm (height) 500 mm Countertop size 800 × 800 mm Vane pump oil supply pressure 50 kg / cm 2 supercharger for Oil pressure 1000 kg / cm 2 Working cylinder maximum stroke 250 mm Working cylinder empty Travel speed 200 mm / min Working cylinder travel speed 0 ~ 6.5 mm / min Working cylinder return speed 400 mm / min
