5 6 7 Axis Small Cnc Press Brake Equipment Electric Double Servo 170ton 3200mm

Double Servo Motors pump control Hydraulic system CNC Press Brake

Application Introduction,

Principe and Features of the machine:

 

1, Structure of CNC Press Brake:
1) Complete steel-welded structure; left and right houses, working table and cylinder base are welded into a whole frame.

2) After welded, the internal stress is eliminated by tempering, so the whole steel is strong and the stability.
2) ANSYS finite element analysis software to ensure the reliability and strength of the machine frame and the bending precision.

2, CNC system to control:

1) All actions (X,R,Z axes running) of the Back-gauge stopper;

2) The stroke of Ram are controlled 

3) The hydraulic system flowing and pressure in two hydraulic servo units

4) The adjustment of deflection compensation

3, Hydraulic system:
1) Integrated control system imported from Rexroth Germany;
2) Two oil tanks with servo main motors+pumps+valves boards driving two sieds cylinderes separately;

3) Decrease the installation of pipelines, less oil is used and oil temperature is low longtime;
4) Ensure the working stability and better appearance.

4, Two main oil cylinders:
1) Closed loop control mode: Germany servo valves boards and imported Grating ruler;

2) High-frequency hydraulic control technology, faster, more efficient and accurate.
3) Totally different from traditional mechanical stop bending machines;
4) High precision of the glide positioning and bending;
 

5, Back gauge stopper:
1) High quality ball screw and linear guider to ensure the stopping precision.
2) More functional multi-axis blocking is available according to customer's requirement.

3) Standard 2 sets of fingers mounted in Linear guider installed on back gauge beam, as to complex shapes work pieces, 4 or 5 fingers back gauge system and corresponding dies are available for your choose.

6, Body two sides:
1) C shaped plates are fitted on both sides;
2) The high precision Grating ruler is fixed between the C shaped plates and Ram;
3) Avoid the influences on bending precision arising from distortion of machine body during bending.

Introduction of Main Parts:

-- CNC controller DELEM DA53T:

-- GIVI Grating Ruler

The CNC Press brake use fully closed-loop electro-hydraulic servo control,

Ram position signals can be feedback to CNC system by two sides Sensor Ruler, 

then CNC controller DA66T adjusts the oil flowing amount by changing the opening size of synchronous valve

, hereby controlling the ram Y1, Y2 running on the same level, maintaining the parallel state of the worktable.

-- Mechanical Crowning/compensation table

•  The local deflection compensation mechanism uses a mechanical interference table compensation structure. CNC controller automatic calculation control.

-- Backgauge stopper,
