Profile bending machine's segmented stepless speed change
Transmission mode and characteristics of section bending machine spindle

There are three configurations for the profile bending machine spindle drive, which are stepless speed change, belt drive shifting and direct drive of the motor. This time we will talk about the infinitely variable way.

Segmented stepless speed change

In the actual production, the CNC section bending machine does not need constant power throughout the entire shift range. Generally, the constant power transmission is required in the middle and high speed sections, and the constant torque transmission is in the low custom section. In order to ensure that the CNC profile bending machine spindle has a large torque at low speed and the shift range of the spindle is as large as possible, some CNC profile bending machines are equipped with gear shifting based on the infinitely variable speed of the AC or DC motor, that is, solving the motor drive and The matching problem of the spindle transmission power makes it a stepless stepless speed change.

In the stepless infinitely variable transmission system with gear shifting, the forward and reverse start and stop of the main shaft and the braking are realized by the electric motor, and the main shaft shifting is realized by the infinitely variable speed of the electric motor and the stepwise shifting of the gear. This configuration is suitable for large and medium-sized machine tools, ensuring high torque output at low speeds and constant power output at high speeds.

In the main drive system with gear shifting, the hydraulic fork and the electromagnetic clutch are two common shifting modes.
