摘要/Abstract

摘要： 为得到高性能的不锈钢填料，采用犁切/挤压翅化加工新技术在用于填料的不锈钢薄带表面加X-出三维茸状翅结构，分析三维翅结构的犁切/挤压成形过程，研究刀具和工艺参数对翅成形的影响规律．结果表明，成翅过程可分为犁切、挤起和挤裂成翅3个阶段；影响翅成形的主要因素为刀具的挤倾角、挤刃宽和犁切/挤压深度；在一定范围内，随着挤刃宽和犁切/挤压深度的增加，翅的高度也增加，而挤倾角对翅高的影响不显著．

Abstract:

To fabricate high-performance stainless steel packings,a new fin-form ing technology named plowing/ex-truding is proposed to machine three.dimension downy fins on the surfaces of stainless steel laminas that are used as packings.The formation process of three-dimension fin by plowing/extruding is analyzed,and the influences of the tool and process parameters on the form ation of the fin are investigated. It is shown that the whole fin-form ing process can be classified into three stages:plowing,extruding and fin forming.and that the extruding obliquity,the extruding edge width and the plowing/extruding depth are the main factors influencing the fin forming. Moreo-ver,within a certain range,the height of fin increases with the extruding edge width and the plowing/extruding depth,but the extruding obliquity has no obvious infl uence Oil the height.
