摘要
超长小锥度薄壁筒形件在航空航天领域有广泛应用。该类零件常采用剪切旋压成形,传统加工过程通常为双段乃至三段拼接组焊而成,耗费材料且工序复杂。目前拟采用一体成形技术,可有效减少工序,提高材料利用率。本文采用ABAQUS有限元软件,建立了D406A锥形件的剪切旋压模型,分析了旋轮进给比,旋轮圆角半径对锥形件剪切旋压壁厚偏差的影响。研究表明进给比为1mm/r,旋轮圆角半径为6mm时,筒形件成形壁厚更均匀,为实现超长小锥度薄壁筒形件的成形提供了理论指导。
Ultra-long small taper thin-walled cylindrical parts are widely used in the aerospace field.Such parts are often formed by shear spinning.The traditional processing process is usually two-stage or even three-stage splicing and welding,which consumes materials and has a complicated process.At present,the integrated forming technology can effectively reduce the process and improve the utilization rate of materials.In this paper,ABAQUS simulation software was used to establish the shear spinning model of D406A conical parts,and the influence of the feed ratio of the rotary wheel and the radius of the rotary wheel on the thickness deviation of the shear spinning wall of the conical part was analyzed.The research showed that when the feed ratio was 1mm/r and the radius of the rotary wheel was 6mm,the forming wall thickness of the cylindrical part was more uniform.It provides theoretical guidance for realizing the forming of ultra-long small taper thin-walled cylindrical parts.
