冲压生产用送料转盘机构及自动控制系统设计

目的针对目前冲压生产中手工送料产生的质量问题,设计一个自动送料旋转托架。方法通过控制矩形波信号发生器输出信号的占空比和频率来控制旋转托架的间歇旋转,利用光电传感器检测旋转托架停止位置来配合冲床完成工件的自动冲压生产。结果该设计能改进现有的手动加工方式,节省人力,实现冲床生产线的自动化运行。结论该设计对同类生产线的送料自动化生产具有参考价值。

Design of Feeding Turntable Mechanism and Automatic Control System in Stamping Production

The work aims to design a rotating bracket for automatic feeding with respect to the quality problem currently resulting from manual feeding in stamping production. The intermittent rotation of the bracket was controlled by the duty ratio and frequency of the output signal generated by the rectangular wave signal generator. The photoelectric sensor was applied to detect the stop position of rotating bracket to cooperate with the punch press to complete the automatic stamping of workpiece. The design could improve the existing manual processing method, save manpower and achieve the automatic operation of punch press production line. Such design provides reference value for automatic feeding on similar production lines.
