High Speed 450 Ton 6000 MM CNC Press Brake Machine with 7 axis
1. Electronic-hydraulic proportional servo synchronization, free
point control within stroke range, repeated precision at ±0.01,
2. Lower working table is fitted with warp offset oil cylinder (fig
below), model from 250T up have both upper and lower and lower
working tables fitted with warp offset mechanism.
3. Very strong anti-deviation capability.
4. The sliding block(Y1,Y2) rear stopper (X,R,Z) and master
pressure control by computer, ball roller leading screw rolling
guide rail are adopted to rear stooper get high precision in
5. Optional digital control, mechanical robot or flexibility
machining center for sheets with 7 axis and up.
Functions and Features
1. This machine possesses the high efficiency of production and
certain accuracy in bending metal plates.
2. It is necessary to select upper die of different shape and lower
die with different width V-groove for bending steel plates of
different thickness, shape of size.
3. With the help of the bending pressure chart or the calculating
formula, the bending pressure can be figured out.
4. By adopting hydraulic driving, it is possible to prevent serious
overload accidents caused by changing of plate thickness or by
inappropriate selection of V-shaped lower die. The machine is
characterized by smooth running, little noise and easy operation,
and its rated pressure in the whole working process is maintained
1. System intermedliate Upper clamps with Anti Wedges
2. Plate Support Arams
3. Powered Depth Axis
5. Light guards
6. Top and Bottom Tooling
7. DELEM DA52 CNC control
8. Germany Bosch-Rexroth Hydraulic
9. Telemecanique/Schneider Electrics
10. Hydraulic and Electrical overload protection
11. Squaring Arm and Front Support Arms
12. Delta inverter with ball screw and polished rod with 0,05mm
13. Side guard is standard meeting CE regulations.
Overall welding process structure
Closed loop control mode composed of imported famous
electric-hydraulic servo valve and measure ruler.
High position feedback precision of sliding block, stable &
precise operation, good
synchronization performance, high accuracy of bending and repeated
positioning of slide block.
Several multifunctional axial of rear stopper device can be used
according to customer’s
Hydraulic system adopt integrated control system to decrease
pipeline installation and oil leak,which will ensure the stability
and beauty shape of tool machine.
The automatic hydraulic & mechanical deflection compensation
structure will eliminate the
influence on product quality caused by deformation of slide block.
The NC system will adjust the compensation automatically. It’s
convenient and with high accuracy.
The CNC system adopt world famous brand, which also been used by
Holland DELEM, Italy ESA,
Swiss CYBELEC, etc.
