Smart Series-CNC Press Brake (PB6) CNC Electric-Hydraulic Proportion Press Brake

  • The machine which features the stable run system and high working pieces make precision is the advanced press brake with CYBELEC Co., Switzerland or DA series of Delem Co., Holland and electric-hydraulic proportional servo valves of HOERBIGER GMBH, or BOSCH GmbH, Germany.
  • The closed cycle type controlling system which is made up of CNC system +linear encode electrical —hydraulic proportional valves + electrical amplifier precisely measure and control the relative position of ram &working table and the synchronous precision .The system keeps the synchronous operation of ram ,and guarantees the pressing depth &angle.

Machine advantage introduction

Machine adopt wholly welding structure, the main parts annealing treatment, releasing internal stress.The machine frame and ram is processed at one time work holding through the technological procedures of heavy duty floor type boring and milling machine.Machine big open height, ram with high speed Ram with quick fastening and crowning device, working table with hydraulic deflection compensation device.Installing advanced aluminum alloy wholly back gauge, X axis, R axis, Z axis with high speed , high precision.Machine standard configuration is Holland DELEMDA52S system, which is 3+1 axisHydraulic system adopt Germany BOSH-Rexroth electric- hydraulic proportional system.

Simulation model engineering and optimization are with famous ANSYS non-linear software(Unique design).

Sheet metal is unpredictable and its characteristics depend on unverifiable factors:

A matter of hundredths

When bending sheet metal, the ram always bows upwards in the centre. There the punch will be farther away from the die.Crowning raises the table to keep the die at a constant distance from the ram. Should we use an incorrect or no crowning, the distance between punch and die will vary along the profile. With an insufficient compensation, the angle will be more open at the centre; conversely, it will be too closed.For this reason, to compensate the machine deformation basing only upon the theoretical sheet metal characteristics results in time losses and material waste. It’s better to measure and then control the compensation in real time, without taking a chance.

Standard Touch comfort for numerical CNC

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