摘要:

为了满足薄壁高筋框体高性能、高效率的制造要求,提出了通过摆动模成形高筋型面,以及采用多台阶飞边结构来约束金属流动的方法,并通过有限元仿真揭示了薄壁高筋框体摆动辗压过程中等效应力、等效应变、温度和载荷的演化规律。结果表明:接触区内金属的等效应力明显大于非接触区,高筋与底板转角区域的等效应力相对较大、等效应变呈阶梯式上升趋势,高筋区域的等效应变明显大于底板区域,并且从高筋顶端至高筋底端逐渐增大;薄板坯温度整体呈降低趋势,高筋与底板转角区域的温度明显高于其他区域;载荷呈周期性波动,摆动模辗压长边与短边交汇的转角区域时载荷相对较大、辗压长边区域时载荷较小。研究结果为实现薄壁高筋框体多自由度摆动辗压塑性变形过程的精确控制提供了理论依据。

In order to meet the high-performance and high-efficiency manufacturing requirements for thin-walled and high-rib frame, the oscillating die was used to form the high-rib prafile, and a method of constraining metal flow by a multi-step flash structure was proposed. Furthermore, the evolution laws of equivalent stress, equivalent strain, temperature and load during the oscillating rolling process of thin-walled and high-rib frame were revealed by finite element simulation. The results show that the equivalent stress of metal in the contact area is significantly greater than that in the non-contact area, and the equivalent stress in the high-rib and the corner area of bottom plate is relatively large. The equivalent strain shows a stepped upward trend, and the equivalent strain in the high-rib area is significantly larger than that in the bottom plate area, and gradually increases from the top to the bottom of high-rib. The temperature of thin plate billet decreases as a whole, and the temperature in the corner area between high-rib and bottom plate is significantly higher than that in the other areas.The load fluctuates periodically, and the load is relatively large when the oscillating die rolls the corner area where the long edge meets the short edge, while rolls the long edge area, the load is relatively small. The study result provides a theoretical basis for the precise control of plastic deformation process of the multi-degree-of-freedom oscillating forming for thin-walled and high-rib frame.
