摘　　要：前轴是汽车重要的承载件之一,本文分析了前轴锻件垂直整形工艺的可行性,通过计算机数值模拟技术模拟并优化垂直整形的工艺参数和模具结构,在模拟分析基础上设计出液压夹紧式垂直整形模。经垂直整形后,锻件弹簧座的上下表面基本压平,可以直接加工螺栓孔并进行安装,减少了后续加工量,并保证了弹簧座的安装要求。Front axle is one of the important load parts in automobiles, the possibility of the front axle vertical finishing process was analyzed, the process parameters and mold structure of vertical finishing process were simulated and optimized with the help of computer numerical simulation technology. A kind of vertical finishing mold with hydraulic clamping system was designed on the basis of simulations. After vertical finishing process in the vertical finishing mold, the upper and lower surfaces of the spring seat are flattening, which can be drilled bolt holes and mounted directly. It is benefit for reducing the subsequent processing amount and meeting, which mounting requirements of spring seat.
