Item Name 1 Clamping screw (UK) / Clamping bolt (US) 2 Adjustment ring Procedure: 1. Undo the clamping screw 2. Adjust stroke by turning the adjustment ring: Rotate to the right: Stroke is reduced Rotate to the left: Stroke is increased 3. Value on the scale roughly represents the stroke up to the stop 4. Retighten clamping screw NOTICE Only tighten the clamping screw lightly to avoid damaging the clamping band! Riveting spindle advance speed adjustment The advance speed of the riveting spindle can be adjusted with the restrictor valve. Procedure: Reducing the advance speed and force build-up: Rotate the level control of the restrictor valve clockwise Increasing the advance speed and force build-up: Rotate the level control of the restrictor valve counter-clockwise NOTICE To have easy access to the restrictor valve, move the riveting unit up to the top position! /ENG 23

24 P [bar] Operation Radial riveting machine RN Riveting force adjustment The riveting force (operating pressure) is adjusted at the pressure regulator of the air maintenance unit. Procedure: 1. Pull the turning handle up out of the detent 2. Set the required operating pressure 3. The value set is displayed by the manometer The operating pressure set determines the riveting force at the form tool (see pressure/force diagram). Pressure/force diagram F [kn] P = operating pressure F = riveting force NOTICE The operating pressure can be set between 1-6 bar. To ensure good functionality, we recommend that the minimum operating pressure of 2 bar is not undershot. The maximum operating pressure is 6 bar and must not be exceeded! /ENG

25 Radial riveting machine RN 281 Operation 5.3 Setting up the riveting machine for a new workpiece Before setting up for a new riveting job, the following requirements must be met: 1. Suitable form tool for the rivet and closing head to be produced 2. Form tool length suitable for calotte radius of pressure cup (Rp) in the currently installed form tool holder NOTICE The form tool length Ls must be selected so that the form-shaping form tool profile cuts directly in the radius centerpoint (see Chapter "Form tools"). 3. Rivet holder or workpiece carrier must be set up centrically to the riveting spindle axis and fixed onto the machine table The following settings must always be made in the control unit "Setup operation" so that the procedure can be interrupted at any time: 1. Insert workpiece 2. Adjust the height of the riveting machine in the stand so that the distance of the form tool to the rivet is smaller than the maximum achievable spindle stroke. If a short cycle time is desired, this distance to the workpiece can be reduced as long as the necessary distance required to insert the workpiece is maintained. 3. Set the required dimension for the rivet path with the stroke limiting stop NOTICE Incrementally lower the stroke limiting ring to determine the correct setting using a test workpiece. 4. At the same time, incrementally adjust the riveting force setting (via pressure regulator) and riveting spindle advance speed (via restrictor valve) to obtain the required results If the workpieces evidence spreading over the height, the stroke limitation may be an obstacle. In this case, the stroke limiting stop should be set slightly lower than necessary. The actual riveting path is then only limited by the termination of the specified riveting time. NOTICE If other system parts may start oscillating due to resonance by the riveting process, check that the tool is in perfect condition and that the workpiece holder is fastened without any play /ENG 25

26 Operation Radial riveting machine RN Possible machine settings Riveting to stroke limiting stop Suitable for workpieces with constant thickness. The necessary riveting path can be finely set by adjusting the stroke limiting stop. The height of the closing head then only spreads by the workpiece height spread value. The riveting time must therefore be sufficient that the stroke limiting stop is also securely reached. During the "riveting out" on the stroke limiting stop, stress is removed and the closing head is cleanly smoothed. Riveting without stroke limiting stop Suitable for parts with differing heights. Instead of a limiting stop, the stroke is limited by the set riveting time. The closing head is then only influenced by the pressure, stroke speed (exhaust valve throttle) and the riveting time. The stroke limitation must be set so that the form tool cannot move into the workpiece carrier when a workpiece is not present. Riveting under high pressure Suitable for rivets where a high hole intrados pressure is required. If a higher pressure is selected for a specific riveting, the riveting time is reduced. The permissible pressure limit is set by the workpiece itself. The opening of the restrictor valve means both a faster advance of the riveting spindle (centre sleeve) and a steeper rise in force. Riveting under low pressure Suitable for joint riveting. A longer riveting time, but lower pressure. The stress on the workpiece is reduced. Possible bending of a rivet pin can be prevented. The partial closing of the restrictor valve also works in the same direction. Advance speed and rise in force takes place slowly. Less material is pressed into the bore, the closing head therefore has more material volume available and will tend to be larger, the intrados remains small /ENG

41 Radial riveting machine RN 281 Options 7.2 Automatic lubrication riveting spindle head The automatic lubrication is recommended mainly for machines and units that are installed in automatic systems and are operated in multi-shifts. It is however also suitable for manual workplaces to ensure regular relubrication of form tool holders and pressure cups. Two machines or units (e.g. RND) can be lubricated simultaneously with a second metering valve. The distance between both machines or units should however not exceed more than 1 meter. A constant air pressure of 6 bar is necessary to operate the device. Setting the grease volume The riveting spindle head is default supplied with approx. 6mm 3 grease. For extremely high loading, this volume can be increased by rotating the level control of the injection lubricator (metering valve) in the "+" direction. One level increases the volume by approx. 1mm 3. Monitoring The level monitoring in the grease container is implemented with an initiator whose control state is shown on the control unit display when the grease volume is too low. Lubrication interval The lubrication interval is specified with the setup parameter in the control unit. The default lubrication interval in the control unit is set to 5h. The default lubrication interval of 5h can be adapted if necessary to the operating requirements. A shorter interval can be set for hard permanent operation in the upper riveting force range or a longer interval for manual insertion operation (see setup table in operating instructions Control ). Topping up the grease container See Chapter "Maintenance and repair work" /ENG 41

50 Maintenance and repair work Radial riveting machine RN Automatic lubrication riveting spindle head (option) Item Name Item Name 1 Injection lubricator (metering valve) 7 Initiator 2 Lubricant line 8 Container cover 3 Solenoid valve 9 Pistons 4 Screwed connection 10 Pressure control valve 5 Plug screw 11 Compressed air hose 6 Grease container (27.6 cm 3 ) Topping up the grease container ATTENTION Container is under pressure! Grease squirts out of container! To topping up stop the compressed air supply! The grease level in the grease container can be determined from the position of the piston. When the end protrudes less than 4 mm out of the container cover or when a corresponding indication appears on the control unit display, the grease container must be topped up as follows: 1. Stop compressed air supply to riveting machine 2. Disconnect compressed air hose at connection 3. Remove the lubricant line and the aperture plug screw on the grease container 4. Push the piston through the aperture down to the stop. Slowly top up with grease (Klübersynth GE ) until it starts to come back out of the same aperture. 5. The grease must leak through the screw connection when the plug screw is mounted again. 6. Reconnect the lubricant line. Manually actuate the injection lubricator several times --> there must not be any air in the lubricant line! /ENG
