NC Accuracy Feeding Steel Coiling Machine Can be Opened MAC4 -800F Press Automation
Compared with the roller feeder and the Hydraulic feeder, the NC feeder has higher feeding accuracy, more stable feeding performance and more convenient operation, and these advantages are derived from its advanced control system.
The control system of the NC feeder consists of PLC, servo system and touch screen. PLC can improve the stability of the control system and enhance the anti-interference ability of the system.
The servo system can accurately position the mechanical movement and improve the accuracy of the mechanical transmission. The touch screen can visually display and modify the parameters of the NC feeder, simplifying the field operation.
The NC feeder has two working modes: manual and automatic. When the manual working mode is used, the servo motor can be rotated forward or reversed. When the servo motor is automatic, the servo motor can only rotate forward.
Description of several key parts of the NC feeder PLC program:
1. the PLC program will set the length of the conversion pulse on the touch screen
2. the pulse number to the actual length
In order to let the operator better understand the working condition of the feeder, real-time display of the feeding length is very necessary. The method is to read the actual pulse number of the PLC, and the multi-faceted hand is converted into the actual length value and displayed on the touch screen.
3. feeding speed to pulse frequency
For workpieces of different lengths, the feed speed requirements are different; longer workpieces require higher feed speeds, otherwise they will conflict with other equipment; shorter workpieces can choose a lower feed speed, which is beneficial to protect the motor.
Therefore, it is necessary to read the maximum speed from the touch screen multiplied by the set percentage, which is the feeder speed, and then convert it into a pulse frequency.
4. pulse frequency transfer material speed
While the feed length is displayed on the touch screen in real time, the display of the feed speed is also very necessary by reading the pulse frequency emitted by the PLC and dividing it by the maximum speed, which is the display percentage.
