Section bending machine is a profile bending machine suited to accomplish the processes of rolling and bending of various profiles.

Features

One roll is fixed and other two bending rolls move up and down, toward fixed rotation center, three rolls are all driving rolls that can be rotated forward and backward. The two bending rolls are hydraulically transmitted, providing smooth transmission and high reliability.
The fixed roll is supported by support rolls at two sides, these support rolls can achieve arc movement and rotation movement. Coupled with guide roll, the profile rolling accuracy can be better controlled.
Three rolls are driven by three high torque hydraulic motors to achieve forward and backward rotation. The rotation motion has a brake system to ensure a precision positioning of workpiece during rolling process.
Main rolls are featured by high strength, rigidity, surface hardness and processing accuracy, can ensure a high reliability and long service life. Three main rolls are supported by spherical roller bearings to reduce friction.
Hydraulic cylinder, central shaft and other transmission parts are all supported by SF-1 oilless sliding bearings.
Overload protection is outfitted to hydraulic system, and control console has an emergency stop button to enable the machine to be stopped immediately.
