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

and defence.

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

backgauge

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

Models available:-
From
250 ton/ 3.2 metre by 250 ton/ 3.2 metre tandem
Up to
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

stress.

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

controlling precision.

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
