Product Description

Durma Fully Hydraulic 4-Roll Double Pinch Manual NC & CNC Plate Rollers Features:

The mechanical and hydraulic systems on HRB-4 machines are designed by experienced Durma engineers. These engineers design the machines utilizing parametric 3D engineering technology (Pro/Engineer) as well as implementation of static and mechanism analysis. All mechanical, hydraulic, and electronic systems are designed
and tested by Durma electrical and mechanical engineers.

  • Stable and Robust Machine Body
  • Strengthen Guiding Systems
  • Planetary Roll Positioning
  • Durable Rolls and Crowning System
  • High Torque Roll Triggering
  • HRB-4 7″ NC Control System – Model DT 7 Control (Standard)
  • HRB-4 CNC Control System (Optional)

Rolls Driven System: By strong body and angular bottom and side rolls, wide angle & small diameter conical parts are easily bent.
While machines in the market are bending conical bending of 3 times of top roll, Durma HRB-4 machines can bend conical bending of 1.5 times easily.

Hydraulic and Electrical System: Machine movements are triggered by hydraulic components. The precision on the all axes are acquired by world leader Bosch Rexroth valves’ high speed response ability and pressure safety valves used against peak pressures and overload, provides protection for motors and other components.
Electrical system designed are compatible with CE safety regulations. The system consists of well known electrical components such as Siemens, Schneider, Phoenix and Opkon. The system is protected by current overloading for its components’, power supplies, electronics and motors. PLC and NC Control Unit are used from EATON.
CNC Control Unit is used from world leader ESA/Gv.

Vertical and Side Support System (OPTIONAL): Optional hydraulic side and vertical supports the sheet’s stretch and prevent deterioration of the bending form in big shaped bending. Movable gauges with hydraulic double cylinders are produced from St52 steel construction. Sheet has easy sliding movement on supports by support rollers which is housing by bearings.

Each support can be controlled from the control panel separately. Vertical and side support system can be controlled automatically in NC mode in CNC and NC machines.

Special Material Support System (OPTIONAL): Especially during bending of a large diameter and thin material ellipse, parallel corners and polycentric shape may
effect the precision and can cause deformation of the material,when there is not enough support from the standard sheet support systems, the Double Knuckle Side Support system may interfere and provides a precise and perfect bending. If needed, the size of the Support System can be built according to the customers request.
