Definitions

  • the invention relates to a wrapping device for fasteners according to the preamble of claim 1.
  • Bumpers made of soft material show high wear and must be replaced quickly.
  • a soft impact buffer a different depth of impact of the fasteners, which e.g. is particularly disadvantageous for nails with their visible nail heads.
  • the invention is therefore based on the object of providing an impact device for fastening means in which the impact sound is damped as much as possible without the usual service life of the impact buffer being impaired.
  • a housing insert is arranged between the main body and the striking cylinder.
  • This housing insert which is separated from the inner wall of the main body in the area of the impact buffer and on the bottom of which the impact buffer rests, prevents the impact sound from being passed on to the housing and thus to the environment. If, according to the invention, the housing insert consists of a plastic with high internal damping, the excess impact energy and thus also the impact sound is largely destroyed in the housing insert.
  • FIG. 1 Wrapping device according to the invention, partially cut.
  • the wrapping device consists in a known manner of a housing 1 with a cup-shaped main body 2 and the associated hollow handle 3, through which the compressed air is supplied from a compressed air source, not shown.
  • the main body 2 is closed at the top by a housing cover 4.
  • the main body 2 has a depression 5 in its upper region, in which a cup-shaped housing insert 6 with an annular flange 7 is mounted.
  • a locking ring 8 serves to hold the housing insert 6.
  • the cross section of the housing insert 6 is dimensioned such that an intermediate space 9 is present between the main body 2 and the housing insert 6.
  • the housing insert 6 has an inclined bottom 10, on which the impact buffer 11 made of elastic material rests.
  • the space 9 also continues in the area of the floor 10 and the main body 2. 6
  • the housing insert is preferably made of the plastics
  • Polyamide or polypropylene, with polypropylene in particular having high internal damping are examples of polyamide or polypropylene, with polypropylene in particular having high internal damping.
  • the percussion cylinder 12 is now mounted between the housing cover 4 and the bottom 10 of the housing insert 6 and guides the percussion piston 13, the percussion plunger 14 of which serves to drive in fasteners, not shown, in a known manner.
  • the blow is triggered and controlled by the known and not described trigger valve 15 with control valve 16.
  • a support cushion 1.8 made of elastic material can be provided between the bottom 10 of the housing insert 6 and between the bottom 17 of the main body 2 to support and fix the housing insert 6. Since such a material also has a high internal damping, the support sound cannot be transmitted from the floor 10 to the main body 2. Rather, additional cushioning of this impact sound occurs through the support cushion 18.
