When a leading progressive stamping
die producer for the appliance industry wanted the ability to
test their dies using state-of-the-art equipment, they turned
to Rowe Machinery & Manufacturing to provide the most flexible
coil feed system available. Rowe is a member of the Formtek Group
and is located in Clinton, Maine.
To meet the demands of the customer,
the line had to offer the ultimate in versatility. The ability
to run critical finish materials from .020" up to .125" thick
and widths from 6" to 50" were a key customer requirement. Another
key requirement was the ability to test blanking, progressive
and gagged tooling.
The equipment provided to meet the
die manufacturer's requirements was a 50" wide by 20,000 lb. coil
capacity light gauge press feeding system. This line features
a H-DSJ series heavy duty single stock reel, designed to hold
one (1) 20,000 lb. steel coil. Coil staging and positioning on
the mandrel is accomplished with a traveling coil car with 24"
of vertical lift. A "C6" Series precision powered straightener
designed for pull-off operation and a PTD-50 threading table are
A high performance, four (4) roll
AC servo feeder was selected for its versatility and superior
feeding capability. The four (4) feed rolls have a matte chrome
finish and are driven by precision, zero-backlash gears operating
in a bath of oil for superior accuracy. This was considered a
critical feature required for testing long part blanking dies.
Since the unit provides twice the normal surface area contact
with the material, reduced roll pressure can be utilized without
causing slippage. This allows accurate testing of prepainted or
polished materials without material marking or distortion.
The Dominator® control, designed
to offer ultimate flexibility in the design and application of
tooling, was provided. The Dominator® control system can be programmed
for up to 10 different lengths and up to 99 repeats of each length
in a pattern (20 lengths optional). Patterns can be repeated automatically
on a continuous basis, or to a preset batch count. An absolute
material positioning arrangement is employed to avoid accumulative
error over the course of a pattern. The control is also equipped
with a jog-to-length feature, which especially speeds progressive
die thread up, and In-motion refinement of feed lengths can be
accomplished while in automatic operation.
The Dominator® control microprocessor
continuously monitors the motor, drive circuits and feed progress
providing extensive fault monitoring. If a fault condition is
detected, the control exits automatic mode and displays a fault
