Electro-hydraulic synchronization CNC Press Brake sheet bending machine servo main motor

Principe and Features of the machine:

●  The frame is made of steel sheet welded structure, left and right houses, working table and cylinder base are welded into a whole frame. After welding, the internal stress is eliminated by tempering, so the whole steel is strong and the stability is good.

●  High-frequency hydraulic control technology, faster, more efficient and accurate.

●  Back gauge of CNC Press Brake is brought standard 2 fingers back gauge system, as to complex shapes work pieces, 4 or 5 fingers back gauge system and corresponding dies are available for your choose.

●  According to input sheet metal datas on Press brake, CNC system can automatically calculate and adjust the table deflection compensation yielding uniform length of all work-pieces angles.

● The distance and height of the rear stopper and the stroke of Ram are controlled by CNC system, which is convenient and quick.

● Oil cylinder has been machined with entire flowings to get the best condition, as forged, Quenched and tempered, and fine grinding, and then hard chromium plating and other processes.  finally assembely 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.

● The use of mechanical deflection compensation gives access to uniform full length workpieces. which can make the table occurs relative movement and form an ideal convex curve, ensuring the relative positions with slider keep unchanged.

Good leakproof 

-- 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 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.
