【摘要】 文中以某大型试验用的薄壁箱体零件为实例,阐述了其设计与加工的方法。以UGNX软件平台为依托,通过研究箱体结构的逆向设计与离散化拆分,实现了基于加工的结构性优化,在此基础上,开展薄壁件钣金成形研究,优化折弯参数,设计折弯工序组合方案,并采用焊接技术完成了箱体整机成形。加工结果表明,薄壁箱体的整机变形控制在2mm以内,满足设计要求。更多还原

【Abstract】 This paper expounds the design and machining method of typical example of thin wall box part with a large test.Based on UGNX software platform,this paper realizes the structural optimization based on processing by the study of reverse design and enclosure structure discretization.On this basis,box machine is formed through the study on sheet metal forming of thin pieces,the optimize of bending parameters,design scheme of bending process combination and the help of the welding technology.The processing results show that the deformation of thin wall box control within 2 mm,meet the design requirements.更多还原
