PBA Series Hydraulic Press Brake Features
  • European style top tool holders with wedge adjustment.
  • Standard tooling: Goose-neck top tool and multi-vee bottom tool
  • Front operated,  back gauge with digital readout control (to 0.1mm precision) and two finger-stops with micro-adjustable height.
  • Ram stroke control by precision mechanical stops built into each cylinder and electrically adjusted by push buttons with a digital position display.
  • Independent position control of one cylinder stops to provide fine angle adjustment and/or conical bending possibility.
  • Pressure switch and gauge to regulate bending tonnage and to prevent over-bending due to bottoming of tools.
  • Pre-set, two-speed bending cycle giving fast approach, slow bending and fast return.
  • 3-function foot-switch: normal bending, beam pause at any stroke point, automatic beam return upon release of foot-switch.
  • Pendant control unit.
  • Hand screw clamps and chains to align and secure bottom die.
  • Two back gauge fingers.
  • Two front support arms

Standard Configuration of PBA Series Hydraulic Press Brake
Estun E21 Controller for press brake

Estun is one of the listed mainstream companies engaged in the domestic robots industry in China which is equipped with completely proprietary technology. The Estun E21 performance is good, block and block shaft can be positioned rapidly and accurately.

Beide-Siemens Motor

From the German brand Siemens motors improve the life of the sheet metal bending machine, and the press brake machine operates in a low noise environment.

Hydraulic Oil Pump

The oil pump adopts a (USA SUNNY) gear pump, which can withstand high pressure and low noise.

Hydraulic Oil Cylinder

lt is recommended to use antiwear hydraulic oil ISO VG46#(the average value of viscosity is 46mm2/s).

Hydraulic Valve Bank

Hydraulic system (Bosch Rexroth) slider can achieve rapid decline, slow down the speed of bending work, and quick return upward, downward and the like during the operation stop of the slider.

Top tool release clamps

The upper mold is a mechanical hook clamp, which is safer when changing molds

Press Brake Toolings

The toolings (punch and die) of the press brake machine are made from Alloy material(42CrMo), and the hardness can reach 42 degrees to ensure the service life of the molds.

Press Brake Electrical System

The power supply of the CNC bending machine adopts a three-phase AC 50HZ380V power supply. After the AC voltage is output from the internal transformer of the system, it can be directly used for the operation of the main motor, and can also be used for the rear gear servo and equipment lighting. The other group forms two groups of DC 24V after rectification, one group is used by CNC controller, and the other group is used by control loop.

Open Door Power off Switch

Once the worker opens the electric cabinet door, the machine will stop immediately.

Front Support

The sheets can be held on the support to ensure that they are pushed one at a time, which is more convenient for bending work.

Press Brake oil Seal Ring

The sealing ring is selected from NOK, which has good sealing performance, reliable work and long life.

Polished rod and guide rail

High precision, low noise, smooth and wear-resistant

Press Brake Stop Finger

High precision fine tuning finger stopper ensures the positioning accuracy.

Optional Configuration of PBA Series Hydraulic Press Brake

Top tool quick release clamps

Up and down finger stop

Ball screw and linear guide
