The NCP Series of single point C frame presses
are an extremely efficient and compact power press loaded with features and are
available in 11 standard sizes. Every size has a standard variable speed motor and is
available in two different stroke lengths and speed ranges. Custom size beds and other
features are available with short lead times.
Frame and Bolster Plate: The over sized
stress relieved steel fabricated frame is machined on late model CNC milling
machines and encloses all moving members. The bed is designed to accept an optional
pneumatic die cushion and has a deflection of .0007" or less per foot. The bolster
plate and slide have T slots machined into it. The slide also features standard size
Drivetrain: All critical parts of the drive
train are machined from JIS SNCM low alloy steel, which is the strongest grade of steel in
its class. The connecting rod is machined with a special buttress thread that evenly
distributes impact for enhanced duration. Crank shafts are precision ground and ride on
automatically greased bronze bearings. Both the primary gears and the transmission shafts
use a precision ground helical tooth pattern for low noise and major torque transmission
and are enclosed in an oil reservoir.
Slide and Gibs: The slide is guided by huge 6
point precision ground gibs fabricated from a special bronze alloy that is far superior
than standard bronze gibs. The slide is equipped with a fully adjustable air
counterbalance with surge tank. The slide and gibs are both automatically
Hydraulic Overload Protection: With this
system the press can never get stuck on the bottom or run during an overloaded condition.
This is accomplished with a hydraulic cylinder connected to the ball seat. In the event of
an overload the cylinder will de pressurize and the machine will stop and display a fault.
The press will now only operate in the inch mode of operation and when the machine is
returned to the top position the cylinder will be automatically reset.
United's Hydraulic overload protection system is fully adjustable,
simply dial in the amount of tonnage that you do not want to exceed with a knob. This
system can also be manually activated with a key switch to unstick dies, just turn the key
and the ram will raise a quarter of an inch.....it is that easy.
Slide Adjustment: A digital die height
indicator is located on the ram that displays the shut height in .1mm increments. Electric
control of the slide adjustment is standard on the NCP 66 and larger presses.
High Quality Wet Clutch is standard on
the NCP 66 and larger. Uniteds wet clutch provides optimal transmission
torque with no shock to press bearings, gears or shafts. Friction coefficient is minimal
for incredibly accurate breaking in a decreased amount of time compared to standard
friction material type brakes. This is a semi permanent device that never needs
adjustment. This mechanism is entirely pollution free to meet updated environmental and
health concerns. A dual safety valve manufactured by Herrion is used for actuation.
Ortlinghaus combination clutch/brakes are standard
equipment on NCP 50 and smaller presses. This high quality German made clutch
is actuated by a Herrion dual safety valve.
Lubrication System: A Vogel automatic
pump is connected to the control to ensure that the crankshaft, gibs, slide and connecting
rod are properly lubricated. Low pressure switches are interlocked to the control to stop
the machine upon loss of lubrication. The ball screw and connecting rod threads are
lubricated by an oil reservoir in the slide that has a site gage located on the front of
it. The flywheel bearings, main gear and pinion gear are lubricated in a self contained
oil bath that also has a site glass.
Optional Equipment: This press can be
equipped at the factory with a wide variety of optional equipment such as light curtains,
tonnage meters, special controls, servofeeds mechanical feeds, complete coil lines,
automation items etc. Contact the factory with your requirements.
Customer Support: A technician from United
Power Press will arrive at your facility at no charge to setup the machine and conduct
training on operation and maintenance. This includes adding all the necessary hydraulic
fluids and lubrication etc. He will not leave the facility until the press is accepted.
Full documentation and prints are supplied with every machine, this includes an electrical
schematic, installation manual, PM manual and operation manual.
Repair parts for this machine are stocked in Johnston RI: Crank, slide, bearings, gibs
etc. for total customer support in the unlikely event of a failure.
|Warranty: All NCP presses come with a three year warranty for
every mechanical component and a two year warranty for electrics and pneumatics.|
