Hydraulic Press Terms
–
A device that converts fluid power into mechanical movement.
– The amount of time necessary
to wait between the molding and appraisal of molded part properties.
–
A defect at the parting line where the material has shrunk inside the
part.
– The
flat surface that supports the material being worked.
– Plates attached to
the rods that carry the platens or any structure mounted to the bed of
a press. It is sometimes removable.
– Any one of several
types of valves that allows flow in only one direction.
–
The lingering deformation after removal of the force, which compressed
the section. An example is when one uses a fingernail to depress a molded
sample; the impression that remains after a time is the compression set.
–
A feature of hydraulic systems that turns the system off and on at set
pressure points.
– The cylinder,
piston, ram, seals and packing of a press.
– The largest capacity,
vertically, that the press can handle or the vertical clearance from the
underside of the ram to the top of the bolster. The ram must be in its
maximum up position.
– The tooling used in a
press for shearing, punching, forming, drawing or assembling metal or
other materials.
– The final opening through
which injected material flows in order to enter a part cavity.
– Circulates
air or water to maintain oil at operating temperature. (http://www.heatexchangers.org)
– Pressure
caused by fluid under applied force.
– Actuation
devices that produce linear motion and force through the use of pressurized
hydraulic fluid. (http://www.hydrauliccylinders.net)
– Pumps that
use mechanical energy to deliver high-pressure fluid flow to the outlet
through pressurized fluid. (http://www.hydraulic-pumps.org)
– A device that
restricts the escape of fluid or entrance of foreign material. (http://www.hydraulicseals.net)
– A device that contains and transfers the flow and pressure of
hydraulic fluid in hydraulic power systems. (http://www.hydraulicvalves.org)
– Removes the part
from the punch/die.
– A press
function that allows it to operate continuously under 10% of its maximum
rated force, as well as to ensure a preheat function at reduced pressure.
– The place where the
mold attaches. It is a series of flat surfaces where one surface is stationary
and the other is moving.
– Long stem or
pole that connects two pieces of the press so that they act together.
– With the ram full
down, it is the clearance over the bed.
– The main feed guide
that runs from the outer face of an injection or transfer mold gate into
a single cavity mold or to runners in a multiple cavity mold.
– Feature that
controls the length of a stroke and can be adjusted accordingly.
– Distance
between the frame member behind the bed to the vertical centerline of
the ram. This measurement affects the size of the piece that can be used.
