Hydraulic Torsion Bar Press Brake TECHNA FAB WC67Y

Why choose this TECHNA FAB Hydraulic Press Brake?

The Chinese manufactured model WC67Y Press Brake uses the older ‘dead stop-torsion bar’ system, which gives a single [Y] axis position and requires that all bending is done in the middle of the Press break the suitability of this dead stop-torsion bar system depends upon your companies manufacturing requirements: Get in touch – we can assist.

The lower specification WC67Y Press Brake price is an attractive proposition.

  • Operator safety, with the SICK DETEC 4 infra-Red light curtains.
  • Protective height 900 mm x 14 mm Resolution,
    with an additional dual safety circuit & additional safety relay.
  • Reliable performance of metal bending, premium brand.
  • Electrical, hydraulic components, available in UK:  reliable UK service & technical support team.

However, a word of caution*
A Bending Brake using a ‘Dead Stop’ system, for the
bending positioning of the [Y] axis is 10 times less accurate in position the [Y] axis depth, than a Synchronised hydraulic metal bending Press Brake.

For sheet metal bending when bending say 2 mm
using say a 16mm ‘V opening, the bend angle will vary around ( + or – 1°), ‘bend to bend’, so a 2° angle variation is possible.

Angle accuracy increases as the lower tool ‘V’ opening increases, so for steel plate bending with a wider ‘V’
the problem decreases

For more information on accuracy, just call us.

Well dimensioned frame, good open height corresponding beam stroke, throat depth etc – check the dimensions out.

ADVANTECH CNC control, a simple system,
easy to use quick to learn.

Options of:  ESTUNE,  DELEMCYBELECESA
CNC control.  Controller options of up to 8 automatic axis, ancillary equipment, offline software.

The TECHNA FAB Standard’ press brake back gauge Commences with 2 automatic axis being [X+R].

Options of up to 2 additional back gauge automatic
axis, being [Z1+Z2]

Lower deflection table option.

Beware of relying too much on a lower bed deflection system, the over use of a lower beam anti- deflection system does create a ‘banana’ effect over the bend length, Anti- deflection systems have a part to play in the metal bending, but they should be used as a ‘fine tuning’ tool

What is a Torsion Bar – ‘Dead Stop’ System?

TORSION BAR

A large‘Torsion Bar’ is attached to the rear of the top beam, the ‘Torsion Bars’ only function’ is to
mechanically hold the top bending beam level
[i.e. the [Y] axis beam] during downward and upward strokes, therefore it stops the top beam from crabbing.

DEAD STOPS

Final bending position of the [Y] axis, i.e. the Left & Right Hydraulic Cylinders, is controlled by ‘Dead Stops’, ‘Dead stops’ are large ‘motorised’ nuts, engaged with large a dimensioned buttress thread, these large dimensioned buttress threads are an extension to the whole cylinder piston, piston rod etc i.e. all machined as a one(1)piece.

FINAL [Y] AXIS POSITION

The 2 ‘Dead Stop’ nuts are both driven by shafts from a central gearbox that is fitted with a rotary encoder to measure gearbox revolutions. The motorised ‘Dead Stop’ nuts position themselves up or down the buttress thread, the final bending position is achieved when the 2 number hydraulic cylinders are hydraulically pressurised,  the hydraulic pressure forces the hydraulic piston downwards until the ‘Dead Stop’ nuts ‘bottom out’ inside each
of the 2 number [Y] axis hydraulic cylinders.

ACCURACY

[Y] axis positional accuracy is controlled by measuring the central gearbox revolutions, offering [Y] axis re positioning accuracy of each [Y] axis stroke of (+ or – 0.10 ), where as a Synchronised Press Brake is 10 x more accurate being  (+ or – 0.01 ) each [Y1+Y2] axis stroke [Y1+Y2] Synchronisation is achieved using 2 number Optical Linear scales positioned at [Y1+Y2].
