摘　　要：对空心工业铝材进行热锻挤压模具设计和3D造型,基于DEFORM软件对挤压过程进行数值模拟。模具设计时优化分流孔入口形状并提出金属流速判据。通过分析模拟结果,采用调整模具工作带长度的方法,改善挤压模出口流速的均匀性,保证了型材质量,有效减少模具开发周期和成本,达到试模、修模的快速响应。The hot forging extrusion die design and 3D modeling of hollow industrial aluminum materials are carried out,and the extrusion process is numerically simulated based on DEFORM software.In the mold design,the inlet shape of the shunt hole was optimized and the metal flow rate criterion was proposed.By analyzing the simulation results,the method of adjusting the length of the die working belt is adopted to improve the uniformity of the exit flow rate of the extrusion die,ensure the quality of the profile,effectively reduce the mold development cycle and cost,and achieve rapid response to mold trial and mold repair.
