基于单片机控制的冲压机床自动供料装置设计

An SCM Control-based Design of Automatic Feeding Device in Punching Machine

提供了自动送料装置的机械本体设计和单片机的控制方案。自动送料装置采用冲压机床冲头的上下运动作为动力源,通过滑块机构、棘轮棘爪机构,实现冲头的上下运动到棘轮水平回转—间歇送料方式。单片机控制实现自动切断机床电机电源停机、供料计数、缺料报警等功能。该装置支持冲压机床连续工作,可大大提高生产率并延长冲压机床制动皮带的寿命,同时避免了工人手部直接进入模具冲压工作区而可能出现的安全事故。

This paper provides a mechanical body design for automatic feeding device （AFD） and the control scheme based on SCM. The AFD takes the movements of the plunger chip as a power source, by the slider mechanism and the ratchet pawl mechanism, and re- alizes the circumrotated-intermission feeding mode. SCM automatically performs the functions of cutting down time of the power of the machine tool motor, counting the supplies and warning of short supplies. The device supports the punching machine to work continuous- ly, can greatly increase productivity and extend the life of the punching machine brake belt, while avoiding the workers＇ hands directly into the die stamping workspace security incidents that may arise.
