In the Nietsetzgeophuse 6 is axially displaceable a Nietsetzkolben 7 arranged at its mouthpiece 5 end facing jaws. 8 for holding a rivet pin, not shown. The jaws are through a Spring 9 biased in a known manner in the closed position.
  • the Nietsetzkolben 7 On the side facing away from the mouthpiece 5 is the Nietsetzkolben 7 with a hydraulic piston 10 of a hydraulically operated piston-cylinder unit 11 firmly connected.
  • Hydraulic piston 10 is within a hydraulic cylinder 12 of the piston-cylinder unit mounted axially displaceable, wherein the hydraulic cylinder 12 coaxial with the Nietsetzkolben. 7 is arranged.
  • Two compression springs 13 clamp the hydraulic piston 10 in the illustration in Figure 1 to the left.
  • a hydraulic chamber 14 On the side facing away from the pressure springs is a hydraulic chamber 14. into which a hydraulic reservoir 15 opens This hydraulic reservoir 15 has via a cylindrical portion 16, in which a piston rod 17 of a piston 18th a piston-cylinder unit 19 protrudes.
  • the piston rod 17 is in the cylindrical Section 16 axially displaceably guided and sealed by means of seals 20.
  • the piston-cylinder unit 19 also has a cylinder 21 in which the piston 18th guided axially displaceable and sealed by seals 22.
  • the piston-cylinder unit 11 and the piston-cylinder unit 19 together form the drive device 4 the rivet setting device, wherein the piston-cylinder unit 11 is hydraulically operated by in the hydraulic reservoir 15 and the hydraulic chamber 14 arranged hydraulic fluid driven becomes.
  • the piston-cylinder unit 19 is driven pneumatically, with the required Compressed air via a valve 23 and compressed air lines 24 an opening 25 in the bottom of the Cylinder 21 is supplied.
  • a hose connection 26 allows the supply with Compressed air.
  • the valve 23 can via an actuating button 27 against the biasing force of a spring 28th operated via a plunger 29 and attached to the actuator button 27 roller 30 become.
  • the actuation of the valve 23 takes place in a known manner.
  • the plunger 29 through the roller 30 is depressed, opens the valve and passes compressed air through the opening 25th in the cylinder 21.
  • an annular magnet 32 is fixedly mounted on the piston 18.
  • a reed switch 33 On the outside of the cylinder there is a reed switch 33.
  • a circuit board 34 is attached to the cylinder 21, on which a controller 35, a power source 36, such. B. a battery and a Display device 37 are located. Control, power source and display 37, z. B. an LCD display are in the usual way with each other and with the reed switch via cable connected.
  • a blind rivet is inserted in a known manner in the mouthpiece 5, wherein the rivet in the mouthpiece and the clamping jaws 8 protrudes.
  • the rivet dome be the jaws against the bias of the springs 9 in a known manner pressed apart and thereby seize the rivet dome.
  • the operator operates the hand-held riveting tool with the operation button 27, wherein the actuating button 27 in a known manner against the bias the spring 28 is pressed into the housing.
  • the roller 30 presses the plunger 29, whereby the valve 23 opens and compressed air from the hose connection 26, or from a compressed air source and the line 24 flows into the valve and from there on via the second line 24 into the opening 25, whereby the compressed air enters the cylinder 21.
  • the magnet 32 Since the magnet 32 is fixedly connected to the piston 18, the magnet is in performing a Nietsetzvorganges raised together with the piston. The magnet will turn on the switch 33, passed a reed contact. Due to the magnetic forces of the magnet the switch is closed so that the controller receives a signal, the digestion about the location of the piston there. In the further course of Nietsetzvorganges when the Piston is moved down from its top position back to its original position the magnet approaches the switch again and thereby generates another signal, that is supplied to the controller, or is processed there. With these two signals is the controller is able to determine if a rivet setting operation has been performed. The Number of signals is divided by two, since the piston during a Nietsetzvorganges with the magnet twice past the switch. If the number of Signals divided by two, you get the number of strokes. If the two Signals occur in quick succession, a Leerhub was performed. The controller can programmed accordingly, so as not to count idle strokes.

  • Due to the known distances L1 and L2 between the switches it is possible to determine if the piston is accelerating or executes a decelerating motion.
  • the speeds are along the Lengths L1 and L2 are substantially the same. Is the speed between the lower the middle switch is larger than between the upper and middle contact, so is pulled a rivet and is not demolished yet.
  • Is the speed between the top Contact and the middle contact greater than between the lower contact and the middle contact the rivet pin is torn off and the piston accelerates after demolition of the rivet thorn. In this case, a working stroke has also been carried out.
  • the third embodiment shown in Figure 4 has a further switch close the initial position of the piston 18.
  • the piston 18 is no longer complete after prolonged operation back to its original position. This can be determined with the fourth switch become.
  • a signal is output, or processed by the controller, so that the operator can be told that oil loss has occurred.
  • a fifth switch is at the top End position of the pneumatic piston provided.
  • This switch can also be another Measuring section are created.
  • this switch can be used to determine whether the device is overloaded or not. If the air pressure is set correctly, it will be the end position of the piston 18 is not reached, it can be assumed that a rivet is set, the requires too much force for this device. This can also be communicated to the operator via a display be, for. By displaying the word "overload”.
  • the control used is a standard microprocessor-inclusive control EPROM / ROM / RAM. But it can also be a freely programmable controller or a hard-preprogrammed controller. There must be enough memory in each case to provide corresponding comparison values for the different measurement paths to be interrogated to store and allow comparisons.
