摘要:
以铝合金环形座锻件为例,采用数字化技术进行了复杂盘饼类锻件等温精密成形工艺及模具的设计,实现了模具设计制造的一体化,提高了模具的设计质量和加工精度,缩短了模具设计和制造的周期,降低了生产成本. 通过有限元模拟和实验相结合,分析了复杂盘饼类锻件成形时的金属流动规律,研究了成形方案对成形质量的影响,并采用优化工艺获得了尺寸精度高、质量合格的7A09铝合金复杂盘饼类锻件. 研究结果表明,采用反挤变形方式可以控制金属的径向流动速度,能有效地防止复杂盘饼类铝合金锻件的折叠缺陷.
Abstract:
Taking the forging of aluminum alloy ring seat as an example, digital technology was used to design the process and the mould of isothermal precision forming of complex disk forging, which contributes to realizing the all-in-one of design and manufacturing of the mould, enhancing the design quality and machining accuracy of the mould, shortening the cycle of design and manufacture of the mould and reducing the production cost. By combining finite element simulation and experiment, the flow law of metal in the forging process of the complex disk forging was analyzed and the influence of the forming scheme on the forming quality was investigated, and then by using the optimal process, complex-shaped 7A09 aluminum alloy disk forging pieces were obtained with high precision and high quality. The results show that the flow velocity of metal in radial direction can be controlled by backward extrusion, which can effectively prevent the folding defect of the complex-shaped 7A09 aluminum alloy disk forging.
