Piranha
Press Brakes are available in a variety of widths
and range from 25 to 400 tons. They may be ordered in
the standard white or Piranha green color. Piranha's
proven design provides four distinct advantages over
other press brake designs.
-
Piranha's mechanical linkage system provides full
tonnage at any point across the ram and bed,
allowing maximum flexibility for multi-operation
set-ups. Operators may place full-tonnage tools
anywhere on the bed. Other press brake designs
require the operator to place any full-tonnage tool
only in the center of the bed, resulting in added
handling and lower productivity. Attempting
multi-operation set-ups on other designs can result
in machine damage. Other designs require more total
machine tonnage for off-center applications.
-
Piranha's Generation II Control System, combined
with the single cylinder hydraulic system, provides
full control reliability in a simple, efficient
design. In the event of a violation of a safety
device, the dual CPU module provides two paths for
signals to stop ram movement. This, with the single
hydraulic valve system, provides the utmost in
simplicity, maintainability, and safety.
-
Piranha's exclusive Preloaded Ram System (PRS)
uses a dynamic system of opposing ram cylinders to
preload the ram prior to movement. This system lifts
the ram into the drive system, eliminating the
influence of ram weight on the bending process.
Furthermore, this system removes the effects of
clearances and wear within the drive system
throughout the life of the press brake.
-
Piranha
utilizes a bed tilt system as opposed to ram tilt
to allow for fade-out bends and to adjust for tool
wear. This system allows the ram to be fully gibbed
and stabilized for parallel movement. Ram tilt
sytems on other designs allow for more play in the
gibs and put unneeded stress on the drive system.
Unlike ram tilt systems on other press brake
designs, Piranha's bed tilt system easily returns to
the "zero" position.

THE PIRANHA
PRESS BRAKE DIFFERENCE
Piranha's Fabrication Series Press Brakes
utilize a heavy duty mechanical linkage system
combined with Piranha's exclusive Preloaded Ram
System to provide the best bending and punching
performance. Full rated tonnage for bending and
punching is achievable at any point across the
bed. This allows the operator the versatility to
set up several tools at once, decreasing part
handling in a production run and increasing
productivity and profitability. |

OUR
COMPETITORS' DESIGNS
Torque Tube Press Brakes
The torque tube or rocker arm design is a
two-cylinder model that does not utilize a
hydraulic compensation system. The torque tube
ties the two end levers together in an attempt
to transfer power between the cylinders to
achieve parallelism. In reality, the tube does
twist. Off-center loading causes the ram to
deviate from parallel, leading to poor die
alignment, uneven bottoming, an d tapered work
pieces. This design cannot achieve full tonnage
anywhere but on center. |

PRESS BRAKE UNIQUE FEATURES
Self-Lubricating Bearings: Piranha's
pivot points are lined with maintenance-free
bearings. These state-of-the art, aerospace
bearings provide high load capacity and low
friction in the form of a thin-walled sleeve.
They are completley non-metallic, require no
lubrication, and provide years of
maintenance-free service. |
|
Inboard Ram Drive: Piranha's ram drive
links are mounted between the "C" frames. This
mounting increases the ram strenght and
minimizes ram deflection. Competitors' press
brakes have a wider ram set which results in
excessive ram deflection. |
 |
|
Minimal Deflection: Piranha's heavy
design and rigitd construction provide superior
bed, ram, and machine deflection
characteristics. This, along with the inboard
drive system, allows less beam deflection for
more accurate operations. Heavy construction
allows ram and bed surfaces to be machined flat
to better accommodate multiple tool set ups.
Competing designs attempt to compensate for
excessive deflection with machined crowning, a
less than satisfactory solution. |
 |
|
Full Length Gibs: Extra-long, hardened
and ground ways are mounted on the massive
Piranha "C" frame to provide maximum support and
guidance for parallel ram movement. Adjustable
gibs ensure the ram is controlled front, back,
and sides. |

PRESS BRAKE STANDARD FEATURES
Bed Tilt Adjustment Wedges: Bed tilt
accomplished from the front of the machine for
fade-outs or cone forming. |
 |
|
Easy-To-Handle Spring-Open Upper Clamps:
Sectional spring-open upper clamps with hardened
clamping bolts ensure quick and easy tooling
changes (Wila and European tooling adapters
available). |
 |
|
Generation II Control System: Embedded
module that allows control of basic and enhanced
features at the operator's fingertips. Provides
full control reliability, ensuring
state-of-the-art safety operations via a dual
CPU integrated circuit. |
