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.

Key words: stainless steel packing, three-dimension fin, plowing/extruding
