摘　　要：在铜材挤压生产过程中,由机后出料系统造成的表面擦伤、划伤及碰伤是一个不容忽视的质量问题。作者在全面分析铜挤压材表面损伤机理的基础上设计出了一种新型的机后出料系统,使制品在从出料台到定尺锯切辊道的运送过程中无滚动、无滑动、无磕碰,从而极大地减轻了出料设备对制品表面的损伤。该系统具有广泛的工艺适应性。实际生产表明,性能可靠,效果良好。In copper extruding process the surface damage caused by post-extrusion system is a quality problem not to be ignored.On the basis of analyzing the mechanism of surface damage,the authors have designed a new type of post-extrusion system,which can convey the extruded products from run-out table to saw conveyer without rolling,slipping and bumping,thus greatly reducing the sur- face damages.The system can meet different process requirements.The productive practice has proved the new type post-extrusion system is reliable and has good effectiveness.
