摘要：

针对某项目锻造工具V型砧对棒料整形工艺的特殊性要求，在原90° 夹角V型砧的基础上，进行了结构改进设计，设计了135°夹角的 V型砧，使其能够满足V型砧对棒料的整形工艺的要求。基于Forge软件对棒料在两种V型砧上的整形成形进行了数值模拟，主要包括棒料的成形效果、棒料成形后的等效应力、应变场；同时，对棒料成形过程中V型砧在热应力和压应力的耦合作用下对砧面的影响进行了模拟，主要包括V型砧所受的耦合等效应力及其成形过程中砧面的磨损。通过模拟结果对比及理论分析，得出了135°夹角V型砧的结构设计不仅能满足工艺要求，而且其所受的应力、应变及磨损较90°夹角的V型砧更小。

For the particularity requirement on a Vshaped anvil forging tools to the bar sizing process, based on 90° Vshaped anvil, its structure was improved, and 135° Vshaped anvil was designed to meet the process requirements of Vshaped anvil forging tools to bar sizing process. Then, the forming bars on the two kinds of Vshaped anvil were simulated by Forge software including the forming effect of bar, the equivalent stress and equivalent strain fields after forming of bar, and the influence of Vshaped anvil on the anvil surface under the coupling effect of thermal stress and compressive stress in the process of bar forming was simulated mainly including the coupling equivalent stress on Vshaped anvil and the wear of anvil surface in the forming process. By comparing simulation results and theoretical analysis, it is concluded that not only the structure design of 135° Vshaped anvil meets the technological requirements, but also the stress, strain and wear are smaller than that of 90° Vshaped anvil.
