Multi axis CNC Sheet metal fabricating Electro-hydraulic Press Brake

Principe and Features of the machine:

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

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

2, Hydraulic system:
1) Integrated control system imported from Rexroth Germany;
2) Decrease the installation of pipelines;
3) Ensure the working stability and better appearance.

3, Main oil cylinders:
1) Closed loop control mode:Germany electro-hydraulic servo valve 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 position and bending;
5) Accurate and stable operation

4, Back gauge:
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.

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

6, CNC controller:

1) All actions (X,R,Z axes running) of the rear stopper by CNC system;

2) The stroke of Ram are controlled by CNC system

3) The hydraulic system flowing and pressure are controlled by CNC system

4) The adjustment of deflection compensation are controlled by CNC system

5) All operations are convenient and quick.

Basic Configuration:

Introduction of Main Parts:

-- CNC controller:

-- Germany Rexroth hydraulic system:

-- Germany EMB Joints

Exquisite shape

Fine tightness

Large flowing

low pressure loss

No oil leakage.

-- GIVI Sensor 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 DA58T 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.
• Each group consists of several groups of three-dimensional curved surfaces with different slopes. The compensation curve is closer to the deformation curve of the slide plate, which greatly improves the machining accuracy of the bending machine.

-- Backgauge system

● X axis drived by servo motor via ball screw

● R axis drived by servo motor via ball screw or Rack and pinion

● Taiwan HIWIN Ball Screw and Liner Guide

● all drivServo Motors

● Manual adjusting the position of fingers

● Z1,Z2 axes drived by servo motor via good Rack and pinion (Optional)

-- Quick Clamping to fix Top tool fastly and easily

--Standard Top tool and Double V-Die (Amada style) on machine

Materials: 42CrMo

Overall quenching process, high hardness and good wear resistance.

Single or Double V-die V8,V12,V16 (customized)
