摘要：

以某型号转向弯臂为研究对象，针对其锻造过程中产生的错位、折叠等问题进行了成形工艺方案分析和有限元模拟，得到了问题产生的原因。提出了将原有工艺中的终锻与校正相结合的方案，将终锻分模面改成V字形分模面。对改进后的方案进行了有限元数值模拟。结果表明：改进后的成形工艺可以生产出合格产品，解决了校正过程中坯料定位难的问题，降低了产品报废率及对工人的要求。成形试验结果表明，采用改进后的工艺方案，在原有设备条件下的终锻最大压力可减小到9000 kN，同时减少了一个工步。从而节省了设备、提高了生产效率、减少了能源消耗。

For the dislocation，folding and other issues occurred during the forging process of steering curve arm, the causes were studied by combining the experiment with the finite element analysis. Then the plan combined final forging with correction in original process was put forward，the parting surface of final forging was confirmed and changed into V-shaped parting surface. The improved process plan was simulated. The result shows that a qualified product can be produced by the improved process, the difficulty of locating for blank is solved during the correction process，and the scrap ratio of product and the amount of workers needed are reduced. The experimental test shows that in the improved process，the maximum pressure of final forging is reduced to 9000 kN，one step is saved without changing the equipment, the productivity is improved，and the energy consumption is decreased.
