摘　　要：在细长杆冷成形自动锻压机新产品的研制过程中,为判断其组合模具结构设计是否符合要求,文中用接触有限元法建立了内衬与外套过盈配合的有限元力学模型。针对内衬和外套的过盈配合状态。采用大型通用有限元ANSYS软件对组合模具进行了有限元分析,得出了内衬与外套在过盈配合状态下的应力分布规律及接触面压力分布状况,找到了应力集中位置和大小。结论表明其组合模具结构配合尺寸设计没有使模具产生变形,该组合模具完全符合产品的设计要求。In the study of automatic forging press＇ new produet which is used for the cold form of the tall and slender pole. in order to judge whether the structural design of the combined die meets the requirement, the finite element and mechanical model of the interference joint between inside lining and outside wrap is established by used contact- finite-element methods. Aimed at condition of the interference joint between inside lining and outside wrap, we carry on the finite element analysis based on ANSYS and attain the stress distribution in interference joint; the pressure distribution in contact face and the location and the size of stress concentration. It is concluded that the structure interference joint size of combined die do not make the mold have distortion and the combined die completely meets the product design requirement.
