【摘要】 随着船舶、航天、汽车、机车车辆等行业的发展，对三辊弯板机的自动化和高精度化提出了较高的要求，尤其是汽车排气管在卷板工序方面的要求非常高。在本文中研发了一种具有新型控制方式的对称式三辊弯板机来卷制2～20mm厚板材，该弯板机能够通过上位机根据板材的目标曲率计算出上辊的下压量并能发送给电机驱动器，上位机同时能够实时采集上辊的实时位置进行波形显示，本文中详细介绍了三辊弯板机的设计过程。更多还原

【Abstract】 With the development of shipbuilding, aerospace, automobile, rolling stock and other industries, higher requirements have been put forward for the automation and high-precision of the three roll plate bending machine, especially the requirements of automobile exhaust pipe in the coiling process are very high. In this paper, a symmetric three roll bending machine with a new control mode has been developed to roll 2～20mm thick plates. The bending machine can calculate the down pressure of the upper roll according to the target curvature of the plate through the upper computer and send it to the motor driver. The upper computer can simultaneously collect the real-time position of the upper roll for waveform display. This paper introduces the design process of the three roll bending machine in detail.更多还原
