Overhung Large Diameter Die Spindle Unit
Available for rolling parts with large shoulders near rolled area, for multiple
form rolling of small parts with segment dies, or for thru feed and cutoff.
DIE DRIVE TRAIN
Its high efficiency spur gear drive system with ground and hardened gears and
roller bearing universals has a torque capability of 750foot pounds. The sealed
gearbox with a 3" diameter pass through hole has self-contained oil bath lubrication. For normal operation a 1.9 to 1 ratio is used. For high speed operation a 1 to 1 ratio is available.
DIE DRIVE UNITS
Standard 25 HP Adjustable Speed Unit
with speed ranges from 150 to 500 RPM
Optional 25 HP Variable Speed Unit
with infinite adjustment over 3:1 maximum to minimum selected speed range
Optional High Speed 30 HP Unit
with selected die speeds up to 1200 RPM
Optional Low Speed 15 HP Unit
with speed ranges from 75 to 250 RPM
HIGH STIFFNESS STRESS FRAME
A rugged steel stress-frame with patented single pivot is combined with the
rugged prestressed draw bar and stiff machine base to provide very low deflection
under full-rated die load.
THRUFEED ROLLING DIE CONTROL
On the thru-feed machine the prestressed drawbar with a micrometer size-adjustment
nut sets and holds the required die gap to excellent repeatability.
COMBINATION INFEED AND THRUFEED ROLL ING DIE ACTUATION
For in feed or in-and-thru-feed operation, die actuation is provided by a 4"
hydraulic cylinder operating through the drawbar. The cylinder, operating at 3000
PSI with a1.7 mechanical advantage, provides a radial load in excess of approximately
54,000 pounds with outstanding closed die position repeatability.
A field-proven 5 HP,5 GPM hydraulic system using a Vickers variable volume pump and
manifold mounted flow control valves provide the hydraulic power.
SPECIAL HIGH SPEED INFEED ROLLING DIE ACTUATION
For infeed rolling applications requiring production ratesfrom30to 120 per minute,
a mechanical die actuation unit is available. Its die closing cam is driven by a
hydraulic motor to provide continuously adjust able cycle speeds through the full
range. It also pro vides a timed power takeoff for any mechanically actuated feed
Single-point precision adjustment of taper is achieved through the use of a
micrometer screw system which provides precise repeatability with independent
AUTOMATIC DOUBLE ACTING DIE POSITIONING
A simple linkage system automatically positions the rolling dies and their support
arms symmetrically about the horizontally fixed rolling centerline. This will permit
diameter and die size adjustment without the need to horizontally adjust either the
die system or any work support and/or feed mechanism.
EXTERNALLY ADJUSTABLE MICROMETER ROLLING SUPPORT UNIT
A cam-operated support unit actuated by an externally mounted micrometer dial
provides precisely repeatable positioning of work-support blade or other fixtures.
STANDARD AXIAL MATCH
A micrometer matching dial with matching spring or optional variable backup spacer
permits axial die match to within .001".
OPTIONAL ROTARY MATCH
An adjustable unit, mountable on the rear end of the left gearbox output hub,
permits precise adjustment of the angular match of the left die to the right.
SPECIAL ELECTRONICALLY CONTROLLED HIGH PRECISION INFEED ROLLING DIE ACTUATION
Where high-precision pitch or form diameter control is required, regardless of
variations in material hardness or other characteristics, the Kine-Tronic preset
table electronic size control system is available. Through the use of direct die
position monitoring, to provide constant die position feedback to the
electromechanical die actuation drive, it is possible to achieve a die position
repeatability of approximately.0002" regardless of other process variables.
Furthermore, this system enables the user to electronically select fast approach,
initial penetration, final penetration, and dwell of the cycle.
