Definitions

  • the invention relates to a stud welding device with several
  • a stud welding device in which several welding outlets, e.g. four, are present that have no different polarity.
  • the disadvantage here is that it is necessary to reconnect the welding cable.
  • Such control units are not optimally suited for use in connection with welding guns operated by robots or in welding lines.
  • the invention has for its object to provide a control device that enables the polarity of the welding outputs to be adapted to the welding tasks that arise in each case.
  • the control unit can be adapted to different welding tasks without having to reconnect the welding cable.
  • a stud welding device is particularly suitable for use in connection with robot-operated stud welding guns or in transfer lines, particularly if this polarity reversal of the welding outputs can be controlled, for example by a program or by remote control. Further refinements of the invention result from the subclaims.
  • the drawing shows a circuit diagram of a stud welding device according to the invention.
  • the stud welding device has a direct current source 1, the positive pole of which is connected to a conductor 3 via line 2. These are e.g. four thyristors 4, 5, 6 and 7 connected with their ends. The cathode connections of these thyristors are connected to plug connections 8 of the welding outputs AG1, AG2, AG3 and AG4. These welding outlets are usually formed by special sockets. If the control electrodes 9 are connected to voltage via switches, not shown, which can be operated by hand on the control unit or are provided for remote control on the welding gun, the thyristors are switched to the on state. This gives the plug connections 8 positive potential.
  • the welding gun is connected in such a way that the stud 10 to be welded has positive potential for a specific welding task.
  • the negative pole of the direct current source 1 is connected to a conductor 12 via a line 11.
  • the cathodes of the thyristors 13, 14, 15 and 16 are connected to this conductor 12.
  • the anodes of these thyristors are connected to plug connections 17 of the welding outputs AG1, AG2, AG3 and AG4.
  • the workpiece 18 is connected to the plug connection 17 of the welding outlet AG1. locks to which the bolt 10 is to be butt-welded. This workpiece 18 is grounded as usual.
  • the stud welding device is preferably designed such that all four welding outputs can only be used one after the other in time.
  • a control (not shown in more detail) is installed, which only switches on the welding output, the welding gun of which is the first to produce the circuit to the welding current source.
  • the negative pole of the direct current source 1 is connected to a conductor 21 via a line 20.
  • Thyristors 20, 23, 24 and 25 with their cathodes are connected to this conductor 21.
  • the anodes of these thyristors are connected to the plug connections 8.
  • Your control electrodes 9 are in turn controllable like those of the thyristors 4, 5, 6 and 7.
  • the positive pole of the direct current source 1 is connected to a conductor 27 via a line 26.
  • the anodes of the thyristors 28, 29, 30 and 31 are connected to this.
  • the cathodes are connected to the plug connections 17.
  • control electrodes 9 are connected in the same way as those of the other thyristors to corresponding switches on the control device or on the welding gun.
  • each of the welding connections AG1, AG2, AG3 and AG4 with their plug connections 8 and 17 can be poled in such a way that the plug connection 8 is positive, the plug connection 17 negative or the connector 8 negative and the connector 17 is polarized positive.
  • the welding outputs AGl to AG4 can be poled alternately from case to case according to the respective welding tasks the. Such requirements arise in particular when such a control device is used for robot welding or in transfer lines.
  • the thyristors can also be connected via preprogrammed actuators.
