3 rolls plate bending machine

Dea 3R

The DEA 3R is a 3-rolls hydraulic machine with variable geometry with full pre - bending.

The main feature that makes the DEA 3R the most versatile machine on the market is its particular geometry that allows it to work as a press brake or as a 4 pyramidal rollers. In fact, its lower rollers move horizontally, while the motorized upper roll makes a vertical movement.



Standard equipment

  • Variable geometry machine
  • Electronically driven machine – integral hydraulic
  • All rolls rotate on double row spherical radial bearings
  • Three rolls with independent positioning movement through hydraulic cylinders
  • Rolls in special carbon steel 42Crmo4, forged quenched and tempered
  • Motorized upper roll with planetary reduction gear + hydraulic motor
  • N ° 3 rotation speeds, selectable from the control panel
  • Side rolls with automatic braking system to prevent metal sheet slippage
  • System to control and use PLC via Internet, for software changes and machine anomalies solutions directly from our headquarters
  • Quick system for changing the upper roll
  • Electronic control of the parallelism of the rolls (with automatic adjustment controlled by SIEMENS PLC) for a perfect balance and a guaranteed tolerance of 0.1 mm
  • Electronic inclination of the upper roll and side rolls, controlled directly by the Siemens Touch Panel
  • The machine is set up with a SIEMENS KTP1200 PN type Touch Panel operating panel with 12 ″ color Touch Screen display.
    By changing the pages it is possible to view on the display: the position of the rolls, set and read the inclination of the rolls, the diagnostic and machine alarm functions
  • Hydraulic unit consisting of: motor pump unit, solenoid valves, maximum pressure valves to protect the system from overload, located in a single manifold block to prevent oil and pressure leaks
  • Heat exchanger to keep the hydraulic oil at the most appropriate temperature
  • Bosch-Rexroth hydraulic components
  • Hydraulic opening bracket to allow the extraction of the tube in a horizontal position
  • Automatic centralized lubrication with preselectable cycle from the touch panel
  • All the controls are placed on an independent control console
  • Siemens electrical components
  • Air cooling system for oil
  • Visualization of alarms and diagnostics on the display to signal all operating anomalies
  • Machine certified according to “CE” or “UL” or “CSA”
  • SICK optoelectronic protective devices for immediate stopping of machine movements
  • Instruction manual in the language of the country of destination, complete with hydraulic and electrical diagrams, drawings of the foundations and all the equipment necessary for the installation of the machine
