采用了导流板保护结构,短分流桥结构和三级焊合室结构,对一工业用铝合金型材挤压模具进行了设计;运用基于任意拉格朗日-欧拉(ALE)有限元法的专用模块HyperXtrude,模拟了坯料在模具中的稳态挤压过程,并对成形中型材的挤出速度、模具的形变与应力情况进行了分析,验证了其设计方案的合理性。探讨了模具优化方案。通过调整工作带长度和芯部壁厚,实现了对金属流动的控制,获得了合格的型材产品。
Adopting the deflector protection structure, the short shunt bridge structure and the three-stage welding chamber structure, an industrial aluminum extrusion die was designed. Based on the finite element method of any Lagrange-Euler (ALE) The special module HyperXtrude was used to simulate the steady state extrusion process of the billet in the mold. The extrusion speed of the shaped medium, the deformation and stress of the mold were analyzed, and the rationality of the design scheme was verified. Discussed the mold optimization program. By adjusting the working belt length and the core wall thickness, the control of the metal flow was achieved and qualified profiles were obtained.
