Steel Plate 7 Axis 400 Ton 6000 MM CNC Press Brake Bending Machine
With CE and CQC
Main Performance
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.
6. The surface of cylinder has good wearing and heat treatment, so it has good lubrication and long service life.
Main Feature:
1.Totallly EU standard design, monoblock by welding robots& apparatus and stress relief process by annealing treatment.
2. Bystricpress engineers utilize parametric 3D Slid works using FEM & DOE analysis as well as static and mechanical analysis.
3. Adopt integrated hydraulic system, more reliable and easy for maintenance and the hydraulic system from Bosch-Rexroth, Germany.
4..Mechanical synchronous mechanism and the complex compensation are designed so as to raise the workpieces precision.
5. The stroke and distance of the backgauge is adjustable by the motor and is well adjusted by hand, the adjustment is displayed by digital meters.
6. Inch, single, continuous operation mode being designed for the machine and reversing and maintain time cane be controlled by the time relays.
7. Safe fence and the electric interlocer have been designed for the machine to ensure the operation safety.
The Main Structure Character
Welded steel plate, the frame consists of right and left wall
boards, working table, oil box, slot steel and etc. The stress of
the welded parts can be eliminated by vibration. The machine enjoys
high accuracy and high strength and can be transported easily.
2. Advantages :
1. Electro-hydraulic servo system, closed loop control system
controls 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 user's
requirements and make the process more convenient and efficient.
5. Y1,Y2 Axis------Two raster displays installed at both sides of ram to control cylinders.
3. Production Introduction:
1. With stylish design, high rigidity, high speed
2. Electro-hydraulic servo system, closed loop control system
controls accuracy
3. Worktable adopts hydraulic deflection compensation to ensure the
accuracy of the workpiece
4. Back gauge is driven by servo motor, adopted ball-screw and
linear guide way, it could make sure positioning accuracy.
