The pipe bending machine is composed of steel frame, lower mold, upper mold, fixture, hydraulic system and mandrel. Its working principle is to make the steel pipe plastic deformation and realize the cold bending of the steel pipe by determining the reasonable fulcrum and stress point and applying bending torque. During bending operation, various large-diameter steel pipes within the applicable range can be cold bent by replacing the die kit and corresponding mandrel.

HGCB series vertical hydraulic pipe bending machine (also called pipe bender) is a specialized equipment for pipeline construction, it is designed and manufactured by Suhigo after introducing advanced technology; the design also considered the actual jobsite operation conditions to make it more user friendly.

Suhigo pipe bending machine is defined according to the pipe diameter, we have 6 models pipe bender to fit for 6~56in pipelines application. At the same time, Suhigo manufacturer mandrel, key component of vertical hydraulic pipe bender.

Technical Parameters of Suhigo Bening Machine:

Technical Features of Suhigo Bening Machine:

1) The operation of all devices is controlled by the hydraulic system, safe and convenient

2) Adopt Cummins national three emission diesel engine and power pack, and low-temperature preheating system can be selected for option, with reliable performance and can adapt to severe work conditions.

3) The hydraulic system adopts top brand components such as Rexroth, and adopts unique preheating and cooling system, which improves the working efficiency and prolongs the service life.

4) The pipe bending operation can be carried out for pipes of different sizes within the scope of application of the pipe bending machine only by replacing the pipe bending die kit and the corresponding mandrel, the replacement is simple and convenient.

5) The whole machine has simple and reasonable structure and easy maintenance. The steel frame made of high-strength steel has long service life and excellent low temperature resistance.

6) Traction crawler walking device or wheel walking device (both are optional) is suitable for field operation, can be selected to the actual working environment.

Hydraulic Mandrel Parameters:

The inclined block mandrel is suitable for the manufacture of 16 "~ 60" pipe bender. It realizes the expansion function through the relative movement of the inclined block, provides constraints for the pipe wall and prevents the deformation of bending pipe. At the same time, through its self-propelled function, it can realize the flexible movement of mandrel in the steel pipe.

Technical Features of mandrel:

1) Base mandrel can be converted to a larger size by using the conversion kit.

2) Self-propelled available from 16"to 60'

3) Polyurethane coated backing bars and wheels to protect internally coated pipe.

4) Simple design and few parts results in low maintenance cost

5) One man operation for expanding, retracting and traveling.

6) Double angle hardened steel wedges provide fast approach and powerful locking action.

7) Wedges will accommodate several wall thicknesses without changing shims

8) Uses the hydraulic system of the pipe bending machine for power.

9) Tapered wheels eliminate rolling.
