摘要
针对数控转塔冲床加工过程中带来的振动与噪声问题,对数控转塔冲床冲裁工艺的动作过程、降噪方案进行了研究,对冲裁过程与连杆结构进行了运动学分析。提出了通过降低冲裁速度,延长冲裁力作用时间以实现静音冲裁的方法;设计了冲头滑块运动曲线图,并通过伺服控制系统,对数控冲床的冲头的冲裁速度、冲裁行程进行了控制;利用Codesys编写了PLC程序,利用试验机床对改进前后的数控转塔冲床的振动与噪声进行了对比测试。研究结果表明:该方法能够明显降低冲裁动作过程中产生的振动与噪声,伺服控制系统可靠性高,冲裁效果好,能够实现静音冲裁功能。
Aiming at the vibration and noise problems brought by the processing of CNC turret punch press,the research was conducted to the action process of punching process and noise reduction schemes of CNC turret punch press,the punching process and the kinematics of the connecting rod structure were analyzed.It was proposed to realize the mute punching by reducing the punching speed and prolonging the action time of the punching force,and designing.The motion curve of the punch slider.The motion control design of the punching speed and the punching stroke of the punch of the CNC turret punch press were performed by the servo control system.The PLC program was written by using the Codesys software,the vibration and noise of CNC turret punch press before and after improvement were measured and compared by the test machine.The results indicate that this method can significantly reduce the vibration and noise caused by punching action,and the control system has high reliability,the punching effect is good,and the mute punching function can be realized.
