ARC Adjustable Structure

Structure of this machine for arc down, end pre-bending of profiles can be carried out, the remaining straight edge is less than or equal to twice times the profile height. The three rollers are active roll, and rolling friction, efficient, energy-saving.

Rollers driven by hydraulic motors hydraulic system of main shaft rotates. Two a side roll by oil cylinder drive, can around in the axis do arc type movement, its function for profiles of bent; again through hydraulic system by motor, gear passed to of power and main roll while do rotating movement, its function for profiles of volume bent forming; supporting roll through oil cylinder drive can do lifting movement, its function for profiles of volume bent forming; supporting roll through oil cylinder drive can do lifting movement, its function for prevent profiles in bent volume forming process in the of around song variant, guarantee bent artifacts of precision.
