Torsion Bar Synchro NC Press Brake

The entire EU streamlined design, heat treatment frame, high rigidity workbench, optional mechanical compensation device for precise bending.

STANDARD COMPONENTS

Mechanical Structure

The main mechanical structure of the press brake consists of the frame, column, ram, worktable, the main cylinder and backgauge. The main components are through finite element analysis and optimized design by 3D software to fully guarantee the structural strength and rigidity of each component.

Controller

Adopt Estun's E21 controller which is able to store 40 programs and each program has 25 steps.

Torque Synchronous Control System

Adopt steel torsion bar synchronization system, the structure is very simple, but the accuracy is very high. At the two ends of the ram, there are two synchronizing devices so that the ram movement is always parallel to the worktable. This structure highlights the effect of balancing motion during operation.

Main Motor

The motor of our press brake is adopt world famous brand "Siemens", which will not only has low noise during working of the machine but also has longer service life.

Oil Pump

China Famous Brand SAEMP/ USA Sunny: Amazing low noise, made of high strength cast iron and unique design for inner noise reduction Low sensitivity to oil pollution and assure of long service life

Hydraulic System

Our press brake machine uses BOSCH-REXROTH integrated hydraulic control system that limits the number of pipe connections, making it more reliable and easy for maintenance.

Electrical System

Our press brake adopts 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.

Backgauge

We using the Taiwan HIWIN ball screw and rod to ensure the moving of X-axis with high accuracy. And the backgauge adopt timing belt & wheel mechanism which controlled by step motor. The up and down movement of the backgauge finger can be adjusted manually.

Punch & Die

The WC67K series press brake is equipped with standard top punch and multi-V bottom die for the use in various purposes. More press brake toolings can be selected as per your practical use.

OPTIONAL COMPONENTS

Fast Clamp

Fast clamp can be used if you need to change the punch frequently.

Rear Light Curtain

The rear light curtain will protect the worker behind the machine.

Front Light Curtain

The front light curtain will be very helpful for protecting the fingers of the operators.

Laser Protection

Does not affect the efficiency of the press brake, can completely solve the safety problem.

Manual Crowning

The crowning will compensate for the deflection of the worktable during bending process so as to obtain higher working precision.

Mechanical Crowning

The motorized crowning system will adjust the parallelism and straightness automatically.
