在工程机械的推进器中,用风马达、丝杠丝母螺旋副的推进形式被广为运用.其中丝杠具有多(头)、大(导程)和长的特点.我们在对一台普通车床(C630)进行改装后,即加长床身,去掉走刀系统及中拖板(包括刀架部分),并在大拖板上安装一专用的挤压器,使其成为一部冷挤压专机,以冷挤住无屑加工新工艺解决了原加工方法的种种困难与缺点. In the construction machinery propulsion, the wind motor, screw nut screw pair is widely used in the form of propulsion.Which lead (multi-head), large (lead) and long features.We are on a After retrofitting the conventional lathe (C630), the bed is lengthened, the pass system and middle carriage (including the tool holder) are removed, and a special extruder is installed on the pallet to make it a cold squeeze Pressure plane, to squeeze cold squeezed new processing technology to solve the original processing methods of the difficulties and shortcomings.
