摘要:

提出了采用多向挤压工艺为复杂枝杈类控制臂锻件成形锻造预制坯。选取典型的复杂铝合金控制臂锻件,通过有限元模拟分析,研究了多向挤压成形过程中毛坯温度、材料流动速度、流线及挤压成形力和模锻成形过程中的温度分布及模具充填情况。模拟结果表明:当坯料成形温度为540 ℃、模具加热保温至200 ℃时,挤压后两枝杈温度为520 ℃,枝杈头部温度约为480 ℃,无须进行二次加热。模锻成形材料变形均匀,模具充填效果好,飞边较小,表明挤压制坯与锻造型腔较好匹配。最后,通过多向液压机对模拟进行了验证,结果表明,多向挤压制坯成形工艺可以获得高质量的控制臂锻件预制坯,该工艺具有可行性。

The multi-directional extrusion process for preformed blank forging of complex branching control arms was proposed, and for typical complex control arms of aluminum alloy, the billet temperature, velocity and locus of material flow, and extrusion load in multi-directional extrusion process as well as the temperature distribution and material filling mold process in die forging process were researched by finite element analysis. The simulation results show that when the extrusion temperature of billet is 540 ℃ and the die is heated to 200 ℃, the temperatures of two branches are 520 ℃ after extrusion, the head temperature of branch is about 480 ℃ and the second-heat is not needed. However, the material deforms uniformly in die forging, the material filling mold effect is good with small flash. It shows that the preformed blank is well matched with the forging mold, and the simulation process is verified by a multi-directional hydraulic press. The results show that high quality pre-blank of control arm forging can be obtained by multi-directional extrusion process, and the above extrusion process is feasible.
