The two (2) rotation stands are powered to
hydraulically lift round bars above the pressure
blocks, then rotate the work for indication and to
position the "high spot" for pressing. The combined
capacity can lift bars up to approximately 15,000 lbs.
and up to approximately 50' in length.
An electric motor drive on one stand rotates textured
drive rollers which in turn rotate the shaft. The
textured surface prevents slippage. The second
rotation stand acts as an idler. A selector switch
controls rotation on/off. All controls are located at
the operator's station.
Each lift/rotation stand uses dual hydraulic cylinders
to power the guided work lift and elevate the workpiece
up and off the pressure blocks to allow rotation.
Independent on-board hydraulic power units drive the
power work lift movements. These self contained power
supplies allow a cleaner work area without the hoses
and plumbing required as from a central source.
Two (2) pressure blocks are provided with V-shaped
anvils. The large bases distribute the press force
across the ribs without bed deformation.
The hardened anvil liners are replaceable. The V-
angle is designed to accommodate round tubes with
surface contact from two sides thereby reducing
contact force on the work to ½ that of a flat anvil
with one point of contact.
The workpieces can be loaded by overhead crane or
fork truck onto the V-blocks.
Pressure Block and The pressure V-blocks and the rotation stands are
electric gear motor powered and positioned by
pushbutton control to traverse across the length of the
bed. Both are driven through dual gear racks on each
edge of the bed which prevent yawing and keep them
centered. The bases have flexible wipers on the edges
to minimize dirt from getting imbedded underneath.
Electric power is supplied to pressure blocks and
rotation stands via integrated festoon cable carrier
system. The cables are suspended from the units and
effortlessly carried along when pulled by a moving
The gantry is powered along the bed of the press by
pushbutton control via an electric motor gear reducer
