A Lubrication Technology for Incremental Forming of 0Cr18Ni9 Stainless Steel Sheet
-
摘要: 数控渐进成形作为一种新兴的塑性加工技术,其摩擦机理比其它塑性加工方法复杂。通过对板料和工具头的表面处理,对0Cr18Ni9不锈钢板料数控渐进成形摩擦机理和润滑技术进行了研究。利用PVD方法在高速钢成形工具头表面镀上一层高硬度耐磨性好的TiAlN涂层;对不锈钢板料进行草化处理使其表面生成草化膜润滑载体。试验结果表明:经过处理后的成形工具头和不锈钢板料,加工出的零件表面光滑,表面粗糙度Ra达到0.94μm,并且工具头没有发生磨损。

Abstract: As a new plastic processing technology,the incremental forming has a more complicated frictional mechanism than other technologies.Through treating the surfaces of steel sheet and tool respectively,we study the frictional mechanism and lubrication technology for the incremental forming of 0Cr18Ni9 stainless steel sheet.We use the physical vapor deposition（PVD） technique to put the high hardness and good wear resistance TiAlN coating on the high speed steel forming tool;we carry out the oxalate treatment of the stainless steel sheet to form an oxalic acidated film as the lubrication carrier.The experimental results show that the stainless steel sheet and tool whose surfaces are treated with our technology have smooth surfaces,with their surface roughness Ra reaching 0.94 μm and the tool thus formed having no wear.-
