CNC MULTI-MACHINE TADEM
HYDRAULIC PRESS BRAKE (BENDING MACHINE)
Product Description
This model of hydraulic press brake(hydraulic bending machine) has
following performance:
model: series 2-WE67K
1 The frame of 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.
2 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 mechanic 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.
3 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.
4 Equipped with good guiding system, position measuring system and
hydraulic balance system to meet the requirements of full length
job and eccentric job.
5 Worktable compensation unit is adopted to make up for deflection
of machine when working to make sure the precision of work piece.
