BLMA: Selection of Controlling system and Servo motor of Pipe Bender
2020-04-13

As an emerging control system of square tube bending machine, the embedded system has obvious control superiority in the industrial field. As a control core with low power consumption, high cost performance, and high flexibility, the embedded system is bound to replace the traditional industrial computer and occupy an indispensable and important role in machine tool control. The embedded measurement and control system is used in the industrial field, especially in the field of CNC machine tools, which will definitely bring a new round of changes to the development of CNC machine tools!


1. Hardware selection of cnc tube bending machine measurement and control system

In the process of designing an embedded measurement and control system for pipe bending machines, the choice of embedded microprocessor is particularly important. The foundation of an embedded microprocessor is the CPU in a general-purpose computer. In order to meet the special requirements of embedded applications, although embedded microprocessors are basically functionally the same as standard microprocessors, various enhancements have been made in terms of operating temperature, resistance to electromagnetic interference, and reliability. The embedded microprocessor has the advantages of small size, light weight and low cost.


2. the selection of the servo motor of the cnc automatic pipe bending machine

Bending machine servo motor is also called executive motor. It is used as an actuator in the automatic control system to convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories of DC and AC servo motors. Its main feature is that there is no rotation phenomenon when the signal voltage is zero, and the speed decreases with the increase of torque. The servo motor is mainly positioned by the servo. The servo motor receives one pulse and rotates the angle corresponding to one pulse to achieve displacement. Because the servo motor itself has the function of sending pulses, the servo motor rotates one every time. The angle will send out a corresponding number of pulses. In this way, the pulses received by the servo motor form a response, or a closed loop. In this way, the system will know how many pulses are sent to the servo motor and how many pulses are received. , You can very accurately control the rotation of the motor, so as to achieve accurate positioning, can reach 0.001mm.
