Hydraulic Drive CNC Tandem Bending Press Brake For Heavy Duty Applications
manufacturing metal sheet hydraulic NC tadem press brake machine
CNC machine tool Performance:
CNC Tandem Series press brakes machine allow for the combination of two heavy duty press brakes
in a synchronised tandem
Typical industries served include earth moving, lighting columns, cranes, aerospace, transport
New intuitive and intelligent DA66T Touch PC based control ensures reduces ‘Art to Part’ time
and optimises bending results
hydraulic press brake bending machine 's Bending parameters automatically controlled by DELEM
unique 'Intelligent' learning database
Multiple operating modes ensure fastest 'Art to Part' times
When used in tandem mode both machines are controlled via one DA66T Touch control
Each machine in the tandem can also be used independently increasing flexibility
Full offline integration and programming via DA66T 3D software
LVD Ttype heavy duty tooling is available to suit your individual application
Machine has many configurable options at point of order: open height, stroke, throat gap and
Additional options are available such as:- automatic tool changing, variable vee dies and
automated material handling
Machine of dissimilar tonnages and lengths can be combined in a tandem configuration for
maximum productivity and flexibility
Can be fitted with DELEM Easy-bend® in process angle monitoring and correction system
250 ton/ 3.2 metre by 250 ton/ 3.2 metre tandem
3000 ton / 14 metre by 3000 ton / 14 metre tandem
Tandems are also available in asymmetric configurations for more details please contact us
digital control CNC press brake machine Description:
1. Electro-hydraulic servo system,closed loop controls slider running accuracy.
2. The unique patented technology:bilateral deflection compensation of the large press brake .
3. Open width adjustable inserts die to meet a variety of workpieces.
4. A variety of auxiliary institutions could meet users’ requirements and make the process
more convenient and efficient.
5. The frame of sheet bending machine is composed of tank, worktable, left and right housings and
ram. So it has high strength and good rigidity. Also it takes vibration to eliminate
6. Synchronization working principal of both machines:Adopting electric-hydraulic
proportional valve to ensure the synchronization of both machines. The proportional valve is
made by BOSCH company with very good performance such as small friction between
action pairs, fine electronic amplifier and electric magnet with high controlling force and
continuous action. There are two raster displayers on both sides of machine to inspect the
position of ram continuously and feed back the signal to control system, then the control
system will control electric-hydraulic valve to make two cylinders synchronization on one
machine. Because the raster displayers are installed to “C” plates, not on housing plates
directly,the deflection of ram and frame when working will not effect its measuring and
When two machines working together, the differential potentiometer installed between two
machines will transfer the mechanic synchronizing signal into electronic one and feed back to
synchronization plate and control system. The signal will be enlarged by BOSCH amplifier to
control the synchronization of both machines by controlling electric-hydraulic proportional valve.
So the synchronization of two machines is achieved with high precision.
7. Through computer,the operator could communicate with machine. The computer has several
service language, calculate and adjust the bending force automatically. Also it could calculate
and control the dead point, speed changing point.The strokes (Y1, Y2) of ram could make a
small tilt to meet the special requirement of user.
8. Equipped with good guiding system, position measuring system and hydraulic balance system
to meet the requirements of full length job and eccentric job.
9. sheet metal press brake Worktable compensation unit is adopted to make up for deflection of machine when working
to make sure the precision of work piece.
10. The surface of cylinder has good wearing and heat treatment, so it has good lubrication
and long service life
