基于PLC的曲轴感应加热装置控制系统设计 摘 要 本设计通过触摸屏与PLC的结合实现对曲轴感应加热的控制，在设计的触摸屏上设置相应的操作按钮，这些操作按钮的存储器地址与PLC的地址相对应[6]，触摸屏接收到操作指令后，通过RS232通信电缆可以将操作信号传送给PLC，PLC接收到正确的操作指令后，将操作信号传送到对应的操作设备，即可实现触摸屏对曲轴的移动、旋转、加热、间隙、冷却等淬火工序的控制，完成曲轴感应淬火的特殊工艺的智能化监控，替代了复杂而繁琐的现场操作， 为曲轴感应淬火提供全自动控制。触摸屏与PLC的结合不仅实现了对曲轴感应加热设备的自动控制，还可以对曲轴整个淬火过程进行智能化监控，便于查找操作过程中出现的故障。触摸屏的自动化、智能化，PLC的强大的内存功能，二者的结合提高了曲轴的淬火质量，极大的增加了加热装置的应用性，提高了生产效率。 关键词：曲轴，感应加热，淬火，PLC，触摸屏 The Control System Design of Crankshaft Induction Heating Device Based on PLC ABSTRACT This design through the combination of touch screen and PLC control system for the crankshaft induction heating, set up the corresponding action button in the design of touch screen, because the memory address of the action buttons correspond to the address of the PLC and touch screen to receive instructions, through RS232 communication cable operation signals to PLC, PLC receives the correct operation instruction, the operation signal to the corresponding equipment operation, touch screen for the movement of the crankshaft can be realized, rotating, cooling, heating, clearance control of quenching process, such as complete induction hardening crankshaft special process of intelligent monitoring, replace the scene of the complicated and tedious operation, provide full automatic control for the induction hardening crankshaft.The combination of touch screen and PLC not only realized the automatic control of the crankshaft induction heating equipment, can also to the whole crankshaft quenching process in intelligent monitoring, easy for operation in the process of failures. The automatic and intelligent touch screen, PLC powerful memory function, improve the quenching quality of the crankshaft, the combination of both greatly increased the applicability of heating device, improve the production efficiency.
