Hydraulic Tandem Sheet Bender CNC 3000T

Hydraulic Tandem Sheet Bender 3000T

The machine is really big Hydraulic Tandem Sheet Bender CNC 3000T machine's wall thickness is 200mm. Machine weight is up to 700T, Huge and heavy duty machine. It is our biggest machine produced for one chinese big company, who is producing sea port crane parts. Max bending thickness is up to 50mm. to make so big thickness tube, we shall us prebending machine to form the plate edge before press brake bending. then we shall use submerged welding machine to do both side welding to finish the tube. the machine has 4 units 55kw electric main motors for each press brake hydraulic system. machine body and bending system is really powerful.

TECHNICAL FEATURES

  • CNC Hydraulic Tandem Sheet Bender are controlled by CNC synchronizing system. All machines Y1, Y2 value will transfer from slave CNC to master CNC. Master CNC will calculate and send command to control each unit hydraulic press brake;
  • Normally each unit of CNC Hydraulic Tandem Sheet Bender has same technical parameters. So that we can synchronize the machines easily. While we also can make different parameters machines to be tandem machine by CNC controller.
  • Each unit of tandem hydraulic press brake is Electric – hydraulic synchronized design; European CNC controller, with full CNC controlled Y1, Y2, calculation based on material and tool library;
  • Automatic bending procedure optimization by CNC controller, engineer can adjust the steps according to actual design;
  • Y1, Y2 is measured with high accurate optic scalars. Measured signal will be feedback to Hydraulic Tandem Sheet Bender CNC controller timely.
  • European proportion valves will control left and right cylinder’s movement according to controller’s command.
  • For tandem press brake, we can apply multi axes back gauge. All the machines can work together to finish all work pieces. Also can separately work as single machine.
  • Ram guide is with low friction Polymer wear-resistant materials, which will give long accurate working life;3000t cnc press brake machine
  • Working table is with automatic crowning system. Hydraulic type is for up to 200T-3.2m machines, while wedge structure is applied for bigger machines.
  • For bending force up to 200T, quick clamp for punch is applied. It will be easy handle the up tooling. The clamp has wedge crowning adjust system.
  • Low noise and high efficient gear pump is standard configuration;
  • Ram is with Anti-tilt device for machine protection;
  • CNC Hydraulic Tandem Sheet Bender Oil tank is with level and temperature indicator.
