Configuration

In addition to the standard tool, the FireRex ® C-WT blind rivet nut setting tool is equipped with sensors for recording the setting force and setting stroke during the setting process. A process data module is integrated into the head housing of the blind rivet nut setting tool that evaluates the recorded process data. The process evaluation is visualised on the blind rivet nut setting tool by means of an LED integrated into the housing. The sensors employed in the blind rivet nut setting tool and the process data module are maintenance-free. Figure 1 shows the configuration of the FireRex ® C-WT with setting process monitoring.

3.2 Process data evaluation
The setting process is monitored on the FireRex ® by evaluating the setting force and setting stroke during the setting process in the material to be joined. The evaluation criteria are the maximum setting force Fm and the setting stroke Sm up to standstill. A blind rivet nut joint is evaluated as OK when this value pair is within a defined evaluation window. If the value pair lies outside this window, or leaves the window to the previously defined side, the process is evaluated as NOK.

Starting procedure

Prior to operating the blind rivet nut setting tool, attach the relevant threaded mandrel with nosepiece to match the thread size.
Before starting the blind rivet nut setting tool, read and observe the operating instructions and safety information and keep in a safe place. Have the compressed air mains connection to the blind rivet nut setting tool made a qualified person. Initial commissioning must also be carried out together with a service technician from GESIPA ®
. For editing of the blind rivet nut setting tool, it must be connected to a PC with Windows 7 or higher using the GESIPA ® GrivCheck 2.0 software and a USB adapter cable (Article No. 1435512).

4.1 Oiler

• To prolong the service life of the pneumatic motor, it should be lubricated by operating the FireRex ®  C-WT blind rivet nut setting tool with oiled air.
• The lubricator may only be integrated in line 6 (twist off).
• The original GESIPA ® oil can be used for lubrication.
• The oiler should be set such that approx. 1 drop of oil is added to the compressed air every 300350 setting operations. One filling of the supplied oiler is therefore  sufficient for 600,000 – 700,000 setting operations.
•  A final oil volume has to be determined over a prolonged period of operation. Pay attention in particular here whether, e.g. oil droplets stick to the device. In this case the oil volume has to be reduced.

4.2 How to change a threaded mandrel

• Disconnect the blind rivet nut setting tool from the compressed air network.
• Detach locknut A, using double open-end spanner SW.
• Unscrew nosepiece B with locknut A
• Push slide K back all the way to buffer and hold tight
• Unscrew threaded mandrel C
• Insert new threaded mandrel C of same size (if worn out) or threaded mandrel C of matching thread size all the way to buffer.
• Release slide. At the same time make sure that the threaded mandrel C is locked safely inside the hexagon socket of the slide. If required, unscrew threaded mandrel C slightly until the slide F locks.
• Insert a matching nosepiece B for each thread size using locknut A and lock loosely with locknut, using a double open-ended spanner.
• Set threaded mandrel length “X”, as described under item 4.3.

4.3 How to set threaded mandrel length “X”

• Detach locknut A, using double open-end spanner.
• Adjust threaded mandrel length “X”, according to nut length (see image 3) by turning nosepiece B.
• Make full use of depth of thread for closed blind rivet nuts (image 3).
• Secure nosepiece B using locknut A.

How to adjust the setting force

The FireRex ® C-WT is adjusted to a setting force suitable for the respective blind rivet nut size (e.g. M6). This ensures that all blind rivet nuts of certain thread dimensions (e.g. M6x15.5 or M6x18) but with differing nut lengths are always set precisely as intended into materials of varying thicknesses.

To adjust the setting force, follow the sequence of operations below:

1. The setting force can be pre-set using the enclosed colour code chart. The right colour code can be selected on the colour code chart according to the nut sizes and the nut materials (e.g. M6 – steel  Colour code red)

2. Using the enclosed hexagon screw driver SW 4, turn the set screw with colour scale I to the selected colour code in the display window.

3. Winding down the blind rivet nut to be set (see item 6.1). Insert the blind rivet nut into the material to be riveted. For materials of varying thicknesses it is advisable to
   select maximum material thickness.

4. Triggering of a setting operation by driving the solenoid valves (1.1 and 1.2). Then check the nut you have set:

• The process can be monitored visually or in the GrivCheck 2.0 software.
• If the nut is not sufficiently deformed during this process, use the hexagon screw driver SW 3 to screw in the set screw with colour scale G by c. 0.5 rotations. Then repeat the setting sequence with a new nut and check once again.
• If the nut becomes too deformed (e.g. difficult to remove; nut thread deformed), the set screw G should be unscrewed about 1 rotation. Then repeat the setting sequence with a new nut and check once again.
  Turning in setscrew G increases the setting force of the rivet tool; unscrewing decreases ethe setting force!

Sequence of operations

6.1 How to wind down a nut

• Position blind rivet nut without tilting on threaded mandrel C.
• Then use the blind rivet nut setting tool to press the threaded mandrel C towards the rivet tool. This action will automatically start the winding down process.
• Do not press activation button!
• Keep a tight hold of the blind rivet nut throughout the winding down process until the blind rivet nut rests on nosepiece B. The winding down process finishes automatically.

6.2 How to set the blind rivet nut

• Insert the wound down blind rivet nut all the way into the drilled hole of the work piece.
• Start the setting process by venting the solenoid valves (1.1 and 1.2)
• When the set setting force is reached (see point 5!), the threaded mandrel moves forward again. The bead breaking process is started by driving solenoid valve (1.3).
• The solenoid valves should be controlled via a PLC supplied by the customer.

6.3 How to remove a nut manually by turning

• If, for example, the solenoid valve is switched too early during a setting operation and the threaded mandrel is therefore not retracted completely, or the nut was positioned crooked during riveting, a bead breaking process can be started manually by driving solenoid valve (1.3) again.
• If the threaded mandrel cannot be retracted by driving solenoid valve (1.3) (e.g. thread in the nut deformed too much), the threaded mandrel can be retracted by hand. To do this, insert the SW 3 Allen key into the socket D on the air outlet of the pneumatic motor (see Figure 1) and turn in anti-clockwise direction to carefully release the threaded mandrel.

Maintenance and care

The blind rivet nut setting tool must be kept in a dry place. Worn threaded mandrels must be replaced as described under item 3.1, as required. After prolonged use it may become  necessary to top up or replace the hydraulic oil. The hydraulic oil should only be replaced by qualified personnel.

To top up the hydraulic oil follow the sequence of operations below:

• Connect the blind rivet nut setting tool to the compressed air network (it moves to starting position)
• Disconnect the blind rivet nut setting tool from the compressed air network.
• Unscrew nosepiece B using locknut A.
• Unscrew oil refill screw I and seal J using Torx screw driver T20.
• Screw on the oil top-up tank with cover supplied and fill to approx. 50% with hydraulic oil
• At threaded mandrel C, move the piston unit carefully back and forth up to the stops by hand until the hydraulic oil comes out bubble-free; push the piston unit completely back and leave at the rear (hydraulic oil level in oil top-up tank drops!). Caution! Ensure that no air is drawn in!
• Unscrew the oil top-up tank from the blind rivet nut setting tool.
• Screw in oil filler plug I with gasket J using a TORX ® screwdriver T20.
• Connect the blind rivet nut setting tool to the compressed air network via a pressure regulator and then set the pressure regulator to 0 bar. Caution! Do not trip the activation button.
• Unscrew oil filler plug I and gasket J using a TORX ® screwdriver T20.
• Screw on the oil top-up tank with cover supplied.
• Gradually increase the air pressure to mains pressure at the regulator; any excess hydraulic oil is pressed out!
• Unscrew the oil top-up tank from the blind rivet nut setting tool and wipe up the escaped hydraulic oil.
• Screw in oil filler plug I with gasket J using a TORX ® screwdriver T20.
• Screw on mouthpiece B with lock nut A.

Regular maintenance will extend the service life of your high-quality GESIPA ® tools and they should be serviced at least every 2 years by an authorised
workshop or by GESIPA ® Service. For tools that are used intensively, we recommend servicing ahead of schedule.
