Metal slitting and slitting machine is a device used to cut wide metal coils longitudinally into a number of narrow strips, and its control system plays a vital role in ensuring that the slitting work is done efficiently and accurately.
Metal slitting shear slitting machine is a kind of equipment used to cut wide metal coil longitudinally into a number of narrow strips, and its control system plays a vital role in ensuring that the slitting work is done efficiently and accurately. The following is a detailed description of the control system for metal slitting machines:
The control system of the metal slitting and slitting machine mainly includes the following parts:
l Main control system: usually consists of PLC (Programmable Logic Controller) or DCS (Distributed Control System), which is used for the integrated control and coordination of the whole system.
l Driving system: including servo motor and frequency converter, used to drive the main knife axis and winding axis, to ensure the stability of tension and speed of metal strip.
l Detection system: including tension sensors, speed sensors, position sensors, etc., used for real-time monitoring and feedback system operation status.
l Human-machine interface (HMI): used for operator-machine interaction, setting slitting parameters and monitoring equipment status.
l Auxiliary system: including lubrication system, cooling system, etc., to ensure the stability and efficiency of the equipment in work.
The design of the control system for the metal slitting and slitting machine is based on the following key principles:
Closed-loop control principle:
The use of tension sensors, speed sensors and other detection elements to monitor the status of the strip in real time, and adjust the drive system through the feedback signal to realize the closed-loop control of the strip tension and speed.
1. Motion control principle:
Adopting servo motors and precision ball screws and other high-precision motion control elements to ensure the synchronized operation and precise positioning of the slitting knife axis and winding axis.
2. Modularized design:
Each part of the control system adopts modularized design, which is convenient for maintenance and upgrading. For example, the main control system, drive system, detection system, etc. are independent and coordinated with each other.
3. Ergonomics principle:
The man-machine interface is designed to be simple and intuitive, so that the operator can easily set parameters, start and monitor the operation of the equipment and reduce error.
4. Redundant design:
Redundant design is adopted in key parts, such as dual power supply, backup servo motor, etc., to improve the reliability and availability of the system.
