摘要:

 基于HyperXtrude软件,分别采用蝶形模和分流组合模对铝型材挤压过程进行了有限元分析,得出两组模具的挤出温度与挤压速度云图。挤出温度和挤压速度的均匀性影响型材质量,只有保证挤出温度和挤压速度的差异率全部都在5%以内,才能保证型材的质量。此次所进行的分流组合模和蝶形模的挤压过程仿真实验中的挤出温度差异率分别为1.10%和1.26%,以及挤压速度差异率分别为1.76%和1.18%,均能保证型材的质量。挤压速度越大,挤压效率越高,挤压机能耗就越低。对比分析得出,在产品质量合格的情况下,相对分流组合模,蝶形模能提高24.66%的挤压速度,大大提高了挤压机的生产效率,降低了铝型材生产能耗。

 

 Based on HyperXtrude software, the finite element analyses of extrusion process for aluminum profile were conducted by butterfly die and diffluent compound die respectively, and the cloud diagrams of extrusion temperature and extrusion speed for two groups of dies were obtained. However, the uniformity of extrusion temperature and extrusion speed affected the quality of profiles, and the quality of profiles was guaranteed only within the difference rate of extrusion temperature and extrusion speed of 5%. Furthermore, the extrusion temperature difference rates are 1.10% and 1.26% respectively, and the extrusion speed difference rates are 1.76% and 1.18% respectively in the extrusion process simulation experiment of diffluent  compound die and butterfly die, which could ensure the quality of profiles. The higher the extrusion speed is, the higher the extrusion efficiency is, and the lower the energy consumption of extruder is. The results show that the butterfly die can increase the extrusion speed by 24.66% which greatly improves the production efficiency of extruder and reduces the energy consumption of aluminum profile production comparied with the diffluent compound die.
