2.1 Operating principles
The pneumatically driven stamping and riveting tool, model
PNP90 SNW-RIV, is used to install rivets. This tool set is special-
ly designed to rivet sheet metal for the automotive industry.
Each tool set consists of a pneumatically-driven hydraulic pump
as well as the rivet clamp with hydraulic cylinder and the appro-
priate rivet mandrels and dies for the rivets in question.
The hydraulic pump is a pneumatically driven pressure intensifier
with an intensifying ratio of 1:100. This means that hydraulic
pressure is one hundred times the preset air pressure. If the preset
end pressure is reached, the pump automatically stops and
keeps this end pressure constant. The hydraulic pump has a
pneumatically controlled pressure relief valve.
The rivet clamp is connected to the pump with a hydrau-
lic hose. This hose is connected to the pump via a leak-free
quick release coupling. The coupling will only release from the
equipment when it is depressurised.
The two pneumatic control hoses must also be connect-
ed to the pump. Make sure that the black hose is attached
to the coupling that is marked for the black hose. Once the
high-pressure hose and the two control hoses have been con-
nected to the rivet clamp, compressed air can be connected
to the equipment.
The two control valves are installed on the rivet clamp, which
activates pump function. Riveting can only be started when
both valves are actuated. If one of the valves is deactivated,
riveting is interrupted and the rivet plunger automatically re-
tracts.
Never bypass either of the control valves or replace
them with other valves! Without the genuine two-hand
control operation, there is a danger of personal injury.
