| 摘 要： | 为了获得TC4某框类零件热挤压成形工艺方案及其合适的工艺参数,利用有限元软件Msc/su-perforge对零件整体热挤压成形和分段热挤压成形两工艺方案进行数值模拟,得出:整体热挤压成形工艺所需挤压力过高,成形困难,不适合该零件;分段热挤压成形工艺所需挤压力低、成形状况良好适合该零件,并以初始挤压温度920℃、挤压速率3 mm/s为成形的合适条件。 |

| Abstract: | In order to obtain forming process scheme and suitable parameters for TC4 titanium alloy frame part, Msc/ Superforge software was used in simulating overall hot extrusion and segment parts hot extrusion. The simulation results show that high extrusion force and difficulty in forming in overall extrusion process made it not suitable for this product,but low extrusion force in segment parts hot extrusion resulted in good shaping. This process is suitable for this product and the initial extrusion temperature 920, extrusion speed 3mm/ s is better condition for it. |
