摘要:

合理的挤压速度规范是实现车架用ZK60薄壁矩形管等温挤压成形的关键因素。 本文基于Deform-3D平台,以ZK60镁合金薄壁矩形管为研究对象,结合Pro/E软件,对该零件的等温挤压过程进行数值模拟分析, 获得了该规格薄壁矩形管的等温挤压成形温度范围及确定了等温挤压速度规范。最后,通过实验验证了本文建立的有限元模型和该ZK60镁合金薄壁矩形管等温挤压速度规范优化结果的正确性。

The proper design of ram speed plays a crucial role in the isothermal extrusion process of ZK60 magnesium alloy thin-wall rectangular tube. The influence law of ram speed on the temperature of thin-walled rectangular tube was investigated and revealed by comprehensive numerical simulations under the Deform-3D software environment combined with Pro/E software. And the temperature range for the isothermal extrusion process of ZK60 magnesium alloy thin-walled rectangular tube was proposed, and the ram speed was deterimined. Finally, the correctness of the optimized results and FE model were verified by experiments.
