吸尘器叶轮上片铝材加工工艺研究

Study on Fabrication Process of Aluminum Plate for Impeller Upper-fins of Dust Collector

详细地研究了吸尘器叶轮上片用 5 0 5 2合金板材的冷加工工艺。结果表明 ,通过采取对铸锭进行均匀化处理和合理控制最终冷轧变形量以及适当提高回火温度的方法 ,可以使材料力学性能与深冲性能获得良好的匹配 ,表面质量稳定 ,完全满足用户的使用要求。

The cold working process of aluminum plate for impeller upper-fins of dust collector was studied in details.The results showed that good mechanical property and deep-drawing property both can be obtained by homogenizing ingot and controlling the final cold rolling deformation properly. Surface quality of final products is stable and in accordance with the requirements of user.
