NC (TORSHION BAR) Press brake E21 Series

NC Press Brakes are synchronous with torshion bar which connected 2 sides of the cylinder, it is conventional standard due to its high cost performance. However as industry products, the nature of all press brake is to create value for its consumers, it is another and more important side to maintain quality simoutaneously with cost reducing.

Torsion bar adjustament parts, optional

As a physical synchronization to be connected by torshion bar, small deform will happans in years of hard work,tollerance emerge and increased.

The unsynchronization performed in the angle difference of 2 sides, which is a headache problem for all users and vendors.

To solve this problem, our team invent this adjustment design on torshion bar, to adjust and eliminate the tollerance, and get back your machine to full precise angle on 2 sides.

Tooling

Our offer includes standard V punch die, with various channel at lower die, for bending of different depth, and equipped with quick clamp system.

Material: 42CrMo, with heat treatment( Quenching), HRC48-52

Arc, sinking, angle dies available, and customer design acceptable.

Free section, for the convenience of combine or small piece.

REQUEST INFORMATION

Crowning systems, V axis (Optional)

Precision: 0.01mm, scope: 0-3mm

Eternity offeres both machanical and hydaulic crowning system both of which ensures a constant bend angle across the full length of the machine. This is achieved by pre loading the machine, to offset any possible deflection under load or compensate for any tool wear, so that under load contacting surfaces are parallel to each other.

With CNC crowning systems the press brake control is preprogrammed with machine characteristics and deflection data.
