For over 20 years, Roper Whitney has been producing quality
folding systems for a variety of markets. Building on that
experience, the Generation "2" Autobrake integrates advanced
design with the features that have made the Autobrake the
choice of professionals.
The Autobrake combines automated bending of angles up to 145
degrees, material clamping, and material support into a
single CNC controlled system employing wing bending
Benefits of the Generation "2" Autobrake system vs.
manual or press brake bending are:
* Reduced labor costs
* Improved part accuracy
* Reduced setup time
* Minimized tool changes
* Improved part quality especially on soft and pre-painted
The Generation "2" Autobrake is a plate and weldment steel
construction, delivering superior performance and features
in a simplified rigid design. End housings are a plate-type
construction bringing drive components close together for
improved stiffness and performance. Actuating mechanisms are
secured in rigid mounts at the outside of the housings,
allowing easy maintenance.
The unique Kombi beam is a fabricated structural prism on
which is mounted tooling to firmly clamp a broad range of
materials, close hems, and withstand the forces generated by
capacity forming operations. Machined into the Kombi beam
180 degrees from each other are the attachment surfaces for
the straight and box and pan tooling. Tools are attached to
the Kombi beam with standard socket head cap screws. Grooves
are provided to secure tools even while the clamping bars
are loosened for adjustment. Rotation of the Kombi beam is
powered by a brake motor driving a sprocket and roller chain
Clamping and hemming are programmed. The upper beam is
driven to program settings on both ends by a brake motor and
eccentric drive of the beam with a connecting shaft.
Clamping and hemming power is delivered to the clamp jaws by
a series of spring washers to provide variable clamping
pressures with a shock-absorbing end stop. This provides
reliable clamping pressure regardless of material thickness.
Integral to the upper beam are the ways with non-metallic
gibing to guide and retain the upper beam within the end
Part program operation and creation are accomplished on a
pendant-mounted computer control, located at the right-h
