Definitions

  • the invention relates to an impactor for fasteners according to the preamble of claim 1.
  • FR-A-1 426 014 discloses an impact device of the type mentioned at the outset, in which the cover plate is provided as a pivotable flap which is held in the closed position on the guide foot by means of a spring in the manner of a snap lock.
  • the cover plate Since the detent spring can easily give in, the cover plate is not held securely and can snap open from the inside even with slight pressure. The durability of the detent spring can further decrease due to manufacturing differences or fatigue. An opening of the cover plate is also to be feared if thickness deviations occur in the fastening means, which is readily possible with a stamped and bent part manufactured in such large numbers.
  • the invention is therefore based on the object of providing an impact device with a cover plate which yields slightly when the fasteners are too thick, without completely opening the opening in the discharge channel and completely releasing the opening in the event of a jamming between the ram and the fastener.
  • the cover plate is raised according to the invention over the latching surfaces of the guide foot, so that the spring relaxes and the opening to the discharge channel is completely exposed. This allows the jammed or bent fasteners to be easily removed. The impact tappet and the parts of the ejection channel are not damaged when jammed.
  • the foldable shaped spring characterized in the subclaims makes it possible to completely remove the cover plate from the guide foot and to remove the jamming. In addition, it is easily possible to use the form spring z. B. to remove completely from the guide foot for replacement.
  • auxiliary tool This can, if it is z. B. is a screwdriver, are used in the transverse grooves provided in the cover plate. It is also easily possible to reinsert and tension the cover plate by pushing the bow of the form spring over a slide-on surface provided on the cover plate.
  • a pivotable catch pawl is provided on the guide foot, which securely holds the relaxed cover plate.
  • an impact piston (not shown) is slidably mounted in a housing 1 and is connected to an impact plunger 2.
  • a guide foot 4 is fastened to the side cheeks 3 of the housing 1 and has an ejection channel 5 which is open on one side.
  • a magazine 6 for receiving fasteners 7, z. B. from clamps, from which these fasteners get into the discharge channel 5.
  • a further support of the cover plate 9 is provided by latching surfaces 11 of the guide foot 4 which are perpendicular to the ejection channel 5 and which rest against the latching surfaces 12 of tabs 13 of the cover plate 9. (See Fig. 2).
  • a shaped spring 14 which has the shape of a U, with a bracket 15 and pin 16 at their free ends.
  • a holding block 17 is connected, in whose bores 18 the pins 16 can be inserted.
  • the cover plate 9 has a nose 19 with a clamping surface 20 inclined to the ejection channel 5, against which the bracket 15 of the shaped spring 14 rests in the tensioned state.
  • stop surfaces 21 are provided on the guide foot 4, against which the form spring 14 is supported upwards.
  • the nose 19 is furthermore provided with a slide-on surface 22 inclined against the ejection channel, by means of which the bracket 15 of the shaped spring 14 can be moved from the open position shown in broken lines in FIG. 1 to the tensioned position shown in solid lines.
  • transverse grooves 24 are provided in the front surface 23 of the cover plate, in which an auxiliary tool, for. B. a screwdriver can be used. (See Fig. 2).
  • a catch 25 is pivotally mounted, the nose 26 engages in a slot 27 of the cover plate 9.
  • the cover plate 9 can either be first inserted into the guide foot 4 and then the form spring 14 can be stretched over the sliding surface 22 by means of an auxiliary tool. On the other hand, it is also possible to bring the cover plate 9 with the shaped spring 14 into the open position shown in FIG. 4 and to move the cover plate 9 up into its closed position by pushing the wrapping device against a suitable surface.
