Hydraulic NC Press Brake ( Torsion Bar )

The hydraulic Press Brake includes a support, a workbench and a clamping plate. The workbench is placed on the support. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a housing, a coil and a cover. It is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the wire is energized to the coil, and the gravitational force is generated on the pressing plate after being energized, thereby realizing the clamping of the thin plate between the pressing plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made into a variety of workpiece requirements, and workpieces with side walls can be processed.

Product Description

Hydraulic Press Brake Torsion Bar E21

New Design 2021 Durmapress Hydraulic NC Press Brake E21 Controller from ESTUN

E21 NC PRESS BRAKE

Standard Features


(1) Hydraulic upper transmission, the cylinders at both ends of the machine tool are placed on the sliding block to directly drive the sliding work.

(2) It adopts mechanical block structure, which is stable and reliable.

(3) The stroke of the slider can be adjusted quickly by motor, fine-tuned manually, and the counter is displayed.

(4) It adopts all-steel welded structure with sufficient strength and rigidity.

(5) The slider synchronization mechanism adopts a torsion shaft for forced synchronization.

(6) Wedge-type deflection compensation mechanism to ensure higher bending accuracy.

Torsion Bar

Torsion Bar Design

Torsion Bar Design to Make the Y1 & Y2 working together , Up & Down 

Press brake stopper finger

Stopper Finger

The Stopper Finger move easily , Left & Right Directions , Manual Control , Easy working , High precision position


Slider stroker.

Slider Stroker

Control the movement of the workpiece and the stroke of the automatic feed to avoid collision accidents. The limit switch on the upper and lower molds of the bending machine protects the terminal limit.


schneider electrical parts

Schneider Electrical 

Our press brake adopt Schneider electrical components. The high quality electric parts can make the machine performing well even the electricity is not stable and customers can easily get the replacement anywhere in the world.


Siemens Motor

Main Motor

Compared to traditional stepper motors, the advantages of using servo motors include: improve the accuracy to ± 0.01mm, the noise decrease to 25 decibels, reduce energy consumption by 60%, consump 70% less hydraulic oil and 30% higher efficiency.


Press Brake Toolings

Toolings &  Die

The standard top punch and dual-V bottom die are specially designed for bending sheet metals. More press brake toolings can be selected as per your practical use. Material and HRC47 degree values are marked on it


valve

Valve

Adopt Germany's Bosch Rexroth integrated structure of oil pump and hydraulic valve to ensure the bending accuracy.
