HYDRAULIC TORSION BAR PRESS BRAKE - COMMENCING WITH 3 AXIS [Y+X+R] TECHNA FAB

Please Enquire

Press Break 

Press break – Hydraulic ‘Torsion’ Bar System
metal bending machine
The  [Y] axis bending position is controlled with ‘Dead Stops’ 

Press Break – TECHNA FAB model WC67Y

Available capacities: 40 to 600 tons – 2200 to 6200 mm bending lengths

The WC67Y Bending Brake specification commences with
 3 automatic axis as ‘Standard‘, being [Y+X+R]
plus 2 manual axis being [Z1+Z2]

The ‘Standard’ CNC Controller is the
ADVANTECH 
controlling up to 4 automatic axis

Operator frontal guarding SICK DETEC 4 infra-Red light curtains
protective height 900 mm x 14 mm Resolution
Photo cell electronic rear entry guarding

Many operator friendly ‘production enhancing’ ancillary equipment options, take a look !!

Press Break

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, we can assist !!

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

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. 
[See notes LH column]

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 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

More info on accuracy, no problem just call us !!,

• 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, t
hese 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]
