摘要/Abstract

摘要： 将多点成形技术思想引入到型材拉弯工艺中,形成三维拉弯柔性成形技术。为了精确地实现型材三维成形,对型材三维拉弯过程中多点模具的自由度进行了分析,设计了可实现4自由度的单元体结构。给出了单元体调形参数的具体计算方法,并提出一种串并结合的单元体调形控制方法。建立了单元体水平和垂直两个方向调形的数学模型。以高铁动车头骨架结构件为例,进行了三维拉弯试验。结果表明:三维拉弯柔性成形装备达到了实际应用的要求。自动化调形技术较人工调形技术生产效率提高60%以上,并降低了劳动强度。

Abstract: A flexible 3D stretch-bending process was developed based on the idea of multi-point forming technique. To realize precise 3D shape of the profile, the freedom of single multi-point die in the process of 3D stretch-bending was analyzed first, and the structure of fundamental unit with 4-DOF was designed. Then, the calculation method of unit adjusting parameters was presented, and a combination of serial and parallel adjustment control method was proposed. In addition, the mathematical model of the unit was set up. With the structural component of high-speed trains as an example, 3D stretch-bending test was carried out. The experimental results show that the flexible 3D stretch-bending equipment meets the practical requirements. Compared with manual adjustment, automatic unit adjustment can improve the production efficiency by 60%, as well as reduce labor intensity.

Key words: metallic materials, metal forming, 3D stretch-bending, fundamental units, shape adjustment, flexible forming
