CNC HYDRAULIC PRESS BRAKE(BENDING
The performance of this type of press brake (bending machine) which
is used to bend metal sheet precisely:
Model: serial WE67K
1. Equipped with DELEM CNC system made in Holland, and other key
parts such as raster display, hydraulic valve, servo motor are all
2. There are two linear scales installed on "C" plates
on both sides, which is fixed on worktable to eliminate the effect
ion of deflection when working. The raster displayers will inspect
the both end positions of ram (Y1, Y2) and send signal. After amplified
by CNC amplifier, the signal will be fed back to computer. Then
the computer will control the volume of oil, which is going to enter
into cylinders. So the parallelism of ram and worktable could be
controlled under under the tolearnce 0.01mm.
3. DELEM system has automatic testing and self-diagnosis functions.
Also, Programming is simply composed of putting in sizes of plate
to bend, dimensions of work piece and choosing tools. Then CNC system
could calculate the bending force and position of back gauge and
ram automatically. Also the ram penetrating and pressing time relay
could be calculated.
4. Good quality electro-hydraulic proportional valve is adopted
to ensure the synchronization of both cylinders as well good capacity
to deal eccentric load.
5. The stroke of ram and back gauge are all controlled by CNC system
with good precision.
6. Main sliding parts such as cylinders, piston rod, guide way,
are all treated with wear-resistance.
7. Back gauge adopts rolling ball screw and rolling guide way, so
the repeat positioning precision of X axis could reach 0.1mm.
8. Full machine is guarded with safety guard with interlocker to
prevent the operator from injured.
CNC control system:
Computer: DELEM CNC system and its performance
A. LCD displayer.
B. Tool Basement and Program basement
C. The synchronization precision of Y1-Y2 could reach 0.01mm and
the precision of backgauge is 0.01.
