Hydraulic Automatic CNC I Beam Cold Bending Machine for sale

YG Machinery manufactures two types of Arch Bending Machines:

  1. Hydraulic Automatic CNC I/H beam Bending Machine
  2. Common Steel Arch Bending Machine

Cold Bending, as the word means, uses the cold method to bend the arch steel. Compared with the traditional version, the Hydraulic CNC I beam bending machine adopts a hydraulic system, has a Digital coding control system, an automatic control system, and is equipped with a Photoelectric control sensor, coded electronic ruler, electronic meter counter.

  • The machine can bend many types of steel bars, like I-beam, channel steel, angle steel, H/U/C-shaped steel.
  • Bending system: The two rollers are made of special materials and are heat treated as a whole to reduce the wear of the cruise ship, no scratches on the workpiece, and long service life.
  • The wearing parts are easy to change, the users don’t need to correct them, just tighten the screws and the machine can work normally.
  • Dual motor drive, hydraulic cylinder propulsion.

Generally, the Steel Arch Bending Machine is composed of 6 parts: base part, mechanical transmission, cold bending system, hydraulic system, electrical control system, and auxiliary system. Feel free to contact us to get the machine price here.

Cold Bending Equipments Working Principle

When the arch bending machine is working, it uses the Door bracket of the auxiliary system to put the I-Beam steel bars enter the two Active rollers. Turn on the hydraulic system, the Hydraulic cylinder will push the Dovetail and Cold roll to bend the H/U/C-shaped steel. When the arc required by the design is reached, turn off the hydraulic system, and activate the mechanical transmission system to make the shaped steel move on so that the machine can work continuously.

Close the mechanical transmission system and turn on the hydraulic system to pull back the Hydraulic cylinder when the bending is over.
