Abstract

With the rapid development of profile processing industry, the processing shape, efficiency, and consistency of profiles are more and more demanding. In this case, the progress of bending machine tools was very important. In this study, the disadvantages and shortcomings of traditional three-roll bending machine are investigated, and a new design of three-roll bending machine is proposed, including a new mechanical structure, hydraulic pressure, and control system. ABAQUS was used to analyze the constrained mode of the table, and the first six order natural frequencies and natural vibration modes were obtained. A mathematical model was established to analyze the relationship between the pressure displacement and the forming radius under ideal working conditions, and the limit position of the downward movement of the lower press roll and the speed relationship between the lower press roll and the support roll are discussed. Based on the experimental data, the nonlinear curve fitting was carried out on the rebound compensation algorithm of asymmetric rolling bending forming. The fitting rebound compensation algorithm was carried out on the symmetric rolling bending forming experiment. The experimental results show that this algorithm can be applied to both symmetric rolling bending and asymmetric rolling bending.

三辊折弯机床设计及补偿算法研究

随着型材加工行业的快速发展，对型材的加工形状、效率和一致性要求越来越高。在这种情况下，弯曲机床的进步是非常重要的。分析了传统三辊折弯机的缺点和不足，提出了一种新的三辊折弯机设计方案，包括机械结构、液压系统和控制系统。利用ABAQUS软件对振动台的约束模态进行分析，得到了振动台的前六阶固有频率和固有振型。建立数学模型，分析了理想工况下压力位移与成形半径的关系，讨论了下压辊向下运动的极限位置以及下压辊与托辊之间的速度关系。基于实验数据，对非对称轧制弯曲成形的回弹补偿算法进行了非线性曲线拟合。对对称轧制弯曲成形实验进行了拟合回弹补偿算法。实验结果表明，该算法既适用于对称轧制弯曲，也适用于非对称轧制弯曲。
