What is the working principle of servo CNC punch press?

How does the servo system of CNC punch press work?

CNC punch press is a high-precision mechanical processing equipment, the core part of which is the servo system. Servo system is the control system of CNC punching machine, which can control the movement and processing of punching machine according to the input instruction. This article will introduce the working principle of the servo system of CNC press.

First, the composition of the servo system

The servo system of CNC punch press mainly consists of servo drive, servo motor and feedback device. Servo drive is the core of the servo system, it can convert the input command into electrical signals, drive the servo motor movement. The servo motor is the actuator, which can convert the electrical signal into mechanical movement. Feedback device is used to detect the position and speed of the motor, and feedback this information to the servo drive.

Second, the working principle of the servo system

1. Position control

The servo system of CNC punch press realizes precise movement and processing through position control. Position control is to compare the actual position detected by the input position instruction and feedback device, and then adjust the movement of the motor according to the comparison result, so as to achieve the purpose of precise position control.

2. Speed control

The servo system can also control the speed of the motor through speed control. Speed control compares the input speed command with the actual speed detected by the feedback device, and then adjusts the current of the motor according to the comparison result in order to precisely control the speed.

3. Torque control

In addition to position and speed control, the servo system can also control the output torque of the motor through torque control. Torque control compares the input torque command with the actual torque detected by the feedback device, and then adjusts the current of the motor according to the comparison result to achieve the purpose of precise torque control.

Third, the characteristics of the servo system

1. High precision: the feedback device of servo system can detect the position and speed of the motor in real time and adjust it by comparing the instruction and the actual value, so as to realize high-precision processing and control.

2. Fast response: the servo drive of the servo system is characterized by fast response, which can respond to the instruction in a short time, thus speeding up the processing speed of the CNC punch press.

3. Strong adaptability: the servo system can adapt to different working environments and processing requirements, and can realize different control strategies by adjusting the parameters to meet different processing needs.
