摘要
对镁合金管材挤压成形进行了工艺实验研究 .确定了镁合金管材挤压成形工艺参数 ,分析了镁合金管材挤压成形时变形力的变化规律 .研究结果表明 ,镁合金管材挤压成形时必须严格控制坯料温度、模具预热温度、润滑剂、挤压速度、挤压比等工艺技术参数 .以上工艺参数对挤压力均有不同程度的影响 .
The technological parameters of tube extrusion of Mg alloy, such as slug temperature, die assembly preheating temperature, lubricant, ratio of extrusion, and extrusion speed, have been determined by experiment in this paper. The extrusion force and influence factors have also been studie. From the results of experiment, it is found that extrusion force has relation to the mentioned parameters.
