CNC Electro-hydraulic synchronization Press Brake for sheet bending

Working Principe and Features:

● The frame is made of steel sheet welded structure, left and right vertical plate, worktable and pressure plate are welded into a whole structure. After welding, the internal stress is eliminated by tempering, so the whole steel is good and the stability is high.

● Latest high-frequency responding hydraulic control technology, faster, more efficient and accurate.

● Optimal ratio of parameters and top-level core configuration ensure stable performance and easy operation.

● HPB standard 2 shafts back gauge system, as to complex shape work pieces, 4 or 5 shafts back gauge system and corresponding dies are available for your option.

● According to state of sheet metal on the press brake, CNC system can automatically control the table deflection compensation yielding uniform length of all work-pieces angles.

● The distance of the rear gear and the stroke of the slider are controlled by the numerical control system, which is convenient and quick.

● The oil cylinder has been forged, Quenched and tempered, fine grinding, hard chromium plating and other processes, and with the import of sealing ring, the phenomenon of oil leakage in customer service.

● The hydraulic system adopts the integrated hydraulic system of oil road to reduce the installation of the pipeline, and the appearance of the hydraulic system is beautiful and concise.

● The use of hydraulic deflection compensation gives access to uniform full length workpieces. Hydraulic deflection compensation consists of a set of oil cylinders under the worktable, which can make the table occurs relative movement and form an ideal convex curve, ensuring the relative positions with slider keep unchanged. Compensation valves are subject to plate thickness and properties of material to be bent.

Introduction of Main Components:

--Holland Delem DA-53T System Features:

The DA-50T-series offers easiest CNC programming based on the Delem graphical touch screen user interface. The new compact DA-53T adds a state of the art complete touch control solution for synchronized press brakes.

This panel based control, standard capable of controlling up to 4 axes, can be integrated in cabinets as well as used in an optional pendulant arm housing. Its 10.1" wide screen high resolution colour TFT, with industrial grade multi touch technology, gives access to the proven Delem user- interface. It enables direct “hot-key” touch navigation between product programming and actual production. Functions are located where needed, offering optimised ergonomics throughout the entire application.

Machine adjustment and test bends are reduced to a minimum with a quick and easy program-to-production work sequence.USB interfacing enables fast product and tool backup using USB memory sticks.

The standard machine control functions are Y1-Y2, X, R-axis and crowning. The second back gauge axis can also be set as Z axis.

DA-53T features:

• “Hot-key” touch navigation
• 10.1" high resolution colour TFT
• Up to 4 axes (Y1,Y2 + 2 aux. axes)
• Crowning control
• Tool / material / product library
• Servo and frequency inverter control
• Advanced Y-axis control algorithms for closed-loop as well as open-loop valves.
• TandemLink (option)
• USB memory stick interfacing
• Profile-53TL offline software

-- High quality Germany Bosch-Rexroth hydraulic system:

-- Germany EMB Tube Connector

Exquisite shape

Good tightness

Large flow, low pressure loss.

-- German BAUSER and Busak+Shamban Sealing Ring

Strong anti-extrusion ability to gap

Elastic seals will not twist or flip

Good leakproof performance

-- GIVI Grating Ruler

Our Press brake using fully closed-loop electro-hydraulic servo control technology,

Ram position signals can be feedback to CNC system by bilateral gratings, then

CNC system adjusts the flowing amount of oil tank by changing the synchronous valve

opening size, hereby controlling the slider Y1, Y2 running on the same level,

maintaining the parallel state of the worktable.

-- Mechanical Compensation/Crowning

• 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.
