摘要：拉丝机是利用金属丝拉拔过程在拉丝模内产生的弹性变形与塑性变形实现金属丝尺寸及物理特性改变的机械设备，其中机架的强度会直接影响拉丝机的生产效率，目前基本都是采用经验来设计与制造。在对拉丝机机架进行深入分析的基础上，结合机架实际受力特点及设计现状，分析拉丝机机架的受力情形后对其进行几何简化，并进行四面体网格划分，采用拓扑优化分析拉丝机机架，根据机架的拓扑优化分析过程、结果及对原模型进行改进，以达到保证强度、优化结构的目的。

Abstract：The drawing machine is used in drawing die wire drawing process of elastic deformation and plastic deformation principle, implementation of wire size and the physical properties change and mechanical equipment. Among them the strength of the frame will directly affect the production efficiency of drawing machine. At present the drawing machine manufacturing industry, the basic experience is used to design and manufacture, based on the analysis about the present situation of drawing machine frame, on the basis of combined the actual frame mechanical characteristics and the present situation of design, do the following three aspects. After the analysis of the stress of the drawing machine frame situation to simplify the geometry, and tetrahedron mesh. The topology optimization analysis drawing machine frame. According to the topology optimization analysis process of the rack, results, and to improve the original model, in order to ensure strength, optimize the structure.
Key words：drawing machine；frame；topology optimization analysis
