Transport and installation
Transport and installation
Transport
 The blind riveting tool will be delivered and erected as agreed, or dispatched in a special
wooden crate.
 Unpacked, the blind riveting tool can be moved on an even floor with the help of the trolley
available under extras. The blind riveting tool must be transported upright by using the two
transport eyes at the top of the feed unit and suitable lifting gear, or secured on a pallet, by
using a lift-truck or high-lift truck.
The blind riveting tool is supplied ready for connection and the sealed
hydraulic system contains approx. 1.2 litre of hydraulic oil. To ensure
stability, transport the feed unit in an upright position at all times
Installation
 Working pressure: min. 6 bar
- The compressed air supply has to be arranged in such a way that 750 NL/min. of dry
dressed, oil-free compressed air is available which must not be allowed to drop below 6 bar
whilst the GAV is in operation (do not use mist lubricator!)
- Pipework diameter 3/4“
The compressed air hose must have an inner diameter of at least
12.5 mm (1/2”) During blind riveting the pressure must not drop below
6 bar; control via pressure gauge showing operating pressure.

5 Commissioning and handling
Commissioning and handling
Prior to commissioning read, and comply with, the
GAV operating instructions and safety instruc-
tions. In addition, comply with occupational safety
regulations.
Commissioning
- Connecting the device to the compressed air
supply network
- Use the pressure reducing valve 1-8002, to set
the operating pressure to 6 bar; control via
pressure gauge 1-8046
- Establishing electrical connection
- Use main switch to turn on device
- Fill about half of the oscillating conveying bowl
and turn on oscillating conveyor (F4 key, see
chapter 8 “Operation”)
- Set the singulator tongue 4-8007 with the help
of the setting screw in such a way that only one
blind rivet at a time is separated
- Actuate the “ON” key
- Trigger the blind riveting gun twice (Menu
“MAN“ function “cycle“). The first blind rivet is
made ready in the expanding mouth piece.
According to the supply details the device is de-
signed for a specific blind rivet size. Despite this,
check that
- the inner diameter of the rivet feed hose 7-8020
is 2-3 mm greater than the setting head diameter
of the blind rivet (setting head diameter max.
11.4 mm)
- the drill hole of the expanding mouth piece 2-80
is approx. 0.3 mm greater than the blind rivet
mandrel diameter. Cylindrically elongated ex-
panding mouth pieces providing up to 15 mm ex-
tension are available for awkquard blind riveting
points (pay attention to blind riveting mandrel
length)
- If required, the clamping force of the expanding
mouth piece 2-80 can be increased by mounting
additional O-rings 2-50.

5 Commissioning and handling
Commissioning and handling
- The appropriate chuck jaws for each blind
riveting mandrel diameter are used.
Chuck jaw scaling is as follows:
- The adjustable deflection sheet leading to
the outlet drain of the oscillating conveyer
bowl 608002 is set in such a way that only
one blind rivet is able to pass this baffle.
- Depending on each blind riveting mandrel
diameter the distance between the chute
sheets 4-8138 is set at an approximate
mandrel diameter of +0.5 mm.
Handling
Insert the blind rivet that is provided in working position inside the blind riveting gun up to its
setting head into the blind riveting hole.
The blind riveting process is triggered by pressing the trigger button, the torn off blind rivet
mandrel is carried off and the next blind rivet is brought automatically into working position.
To allow the next blind rivet to be conveyed from the expanding mouth piece without hin-
drance, the blind riveting gun has to be pulled away from the blind riveting point immediately
after the blind rivet mandrel is torn off.
The remaining mandrels are conveyed automatically to the collecting basin. Afterwards the
vacuum extractor (VE) is turned off automatically.
The collecting basin holds approx. 1800 to 5500 remaining mandrels (depend-
ing on size). Ensure that the collecting basin is emptied in good time.
The blind riveting gun can be hung up ready for use at the work place with the help of a bal-
ancer.
The feed unit must be placed and used on even ground only. The operator has to ensure al-
ways its stability.

Sequence of operations
The fully automatic blind riveting tool GAV-electronic comprises a feed unit and a handy blind
riveting gun which are connected by a flexi-hose assembly.
The feed unit comprises an electronic control with dialogue box, two hydraulic pressure trans-
mitters, an electrical blind riveting conveyor unit and a remaining mandrel extractor with mandrel
collecting basin.
When the blind riveting gun is triggered, the blind rivet waiting inside the nose piece is proc-
essed, the torn off blind riveting mandrel is conveyed to the collecting basin and the reloading
process is triggered automatically.
The oscillating conveyor unit with cut-off automatic ensures continuous provision of blind rivets.

7 Functional units of feed unit
Blind rivet singulator (II)
Part of blind riveting feed appliance. Here, the blind rivet (10) is separated and conveyed by
compressed air through the conveying hose to the blind riveting gun.
Pneumatic-hydraulic pressure transmitter (III)
actuates the pressure piston (8); thereby triggering the unlocking stroke for the expanding
mouth piece.
Pneumatic-hydraulic pressure transmitter (IV)
actuates the pulling piston (7) to carry out the blind rivet setting lift and the rear side of the pres-
sure piston (8) to lock the expanding mouth piece (1) during the setting process.
Whilst the piston system is moving forward and back inside the pressure transmitter (IV) im-
pulses are accepted via the cylinder switch for function operations.
Valve (V)
turns on the readjusting air, thus returning the complete piston unit (7/8) to initial position. The
stop piston (5), chuck jaw hose (4) and snap collet (2) are kept by the relevant pistons in locking
or final position until the completion of the blind riveting process by the pending readjusting air.

The readjusting air interconnected by the valve (V) is waiting and keeps the complete piston unit
(7/8) in back stop position. The snap collet (2) locks the segments of the expanding mouth piece
(1) at their undercut. The chuck jaws (3) are kept locked by the chuck jaw hose (4) on the blind
riveting mandrel (9).
Function image 2
When the GAV is actuated the pulling piston (7) will be actuated by the pressure transmitter (IV)
and the blind rivet setting process will be carried out. The blind rivet is set. The readjusting air is
still pending.

The pulling piston (7) is being actuated by the pressure transmitter (IV) and moves to back stop
position. When the valve is switched (V) the readjusting air escapes. This relieves the stop pis-
tons (5) as well as the chuck jaw hose (4) and the chuck jaws (3) release the blind riveting man-
drel (9). The blind riveting conveying air is turned on by a switch impulse on the pressure
transmitter (IV), the blind rivet (10) supplied by the singulator (II) is loaded and the torn off blind
riveting mandrel (9) is ejected.

The readjusting air is interconnected by the valve (V) and the pulling piston (7), as well as the
piston of the pressure transmitter (IV), is reset at initial position. Simulteneously, the pressure
piston (8) is actuated by the pressure transmitter (III) and carries out the unlocking stroke for the
expanding mouth piece (1). The blind rivet mandrel (9) is taken over by the gripping mechanism
and centred inside the chuck jaws (3).
Function image 6
Whilst the pulling piston (7) continues to reverse, the blind riveting mandrel (9) hits the stop pis-
ton (5), so that the expanding mouth piece (1) is opened by the blind rivet (10) bringing it into
processing position. The pressure transmitter (III) relieves the pressure piston (8) which carries
out the locking stroke for the expanding mouth piece (1). Triggered by a switch impulse on the
pressure transmitter (IV), the singulator was furnished with a further blind rivet (10).
