在分析Ω形丝的形状特点、辊模孔型几何特性及金属在孔型内的变形复杂性的基础上,结合实践经验,采用五道次连续辊拉成形Ω形丝,其中前四道采用倒Y型三辊辊模拉拔成形,第五道次采用无芯两辊辊模拉拔成形。应用AutoCAD软件设计计算了各中间坯的几何形状(孔型形状);应用Pro/E软件设计了各道次的辊模三维装配图,实现了辊模的交互式设计,缩短了设计制造周期,为进行精密异型丝的孔型设计提供了理论指导。

On the basis of fully analyzing the shape characteristics of Ω wire,geometry characteristics of the rolling die pass and the metal forming complexity within the rolling die pass,Ω wire was continuously drawn through five groups of roller dies by combining with the practice experiences.Among them,Y model,which composed of three rolling dies,was applied before the fourth times,and the two rolling dies were used to draw on the fifth times.The geometry shape of its middle billet,which was the molding shape of rolling die,was designed by applying AutoCAD software.Moreover,assembly drawing was also designed by Pro/E software.Based on the above work,the alternant design was realized,and the design and manufacture's cycle time was shortened,too.All the jobs will provide theoretic guidance for producing special shape wire of high quality.
