1.3 Designations
Designations on the stamping and riveting tool
2.1 Operating principles
The pneumatic/hydraulic universal tool PNP 90 UN 2.0
was specially developed for all common riveting opera-
tions in thin sheet metal structures.
The equipment‘s universal technology enables adap-
tion of various attachments for different applications.
The basic tool kit comprises the pneumo-hydraulic
pressure intensifier PNP 90 and a hydraulic actuator
with hose assembly. The kit is completed by an NB 40
rivet clamp and a fully equipped RIVKIT UN 2.0 riveting
tool kit.
The hydraulic pump is a pneumatically-driven pressu-
re intensifier with a pressure ratio of 1:100. This means
that a hydraulic output pressure of 600 bar is gene-
rated with an input air pressure of 6 bar. When the
equipment‘s preset final pressure is reached, the pump
stops automatically and keeps this pressure constant.
The hydraulic pump has a pneumatically-controlled
pressure relief valve.
The hydraulic actuator is connected to the hydraulic
pump via a high-pressure hose. The hose is connected
to the pump via a leak-free quick release coupling. The
coupling can only be connected to the equipment
when it is depressurized.
The two pneumatic control lines are also connected
to the pump. Make sure that the black and the blue
hoses are inserted in the couplings with the relevant
markings.
Compressed air can be connected to
the equipment as soon as the hydraulic
hose and the control lines are connected
to the pump.
The hydraulic actuator is equipped with a control valve
that activates pump operation. The operating lever is
equipped with a safety catch to prevent unintended
operation.
If the valve is activated, the pump begins to run and
the hydraulic plunger extends.
If the operating lever is released, the pump is deacti-
vated and the hydraulic plunger retracts to its original
position.
