Definitions

  • Such bumpers are used in particular in pneumatically actuated fastener driving machines, e.g. Nail driving tools, used to brake the percussion piston of the driving tool and at the same time to reduce the impulse noise generated during each working cycle.
  • pneumatically actuated fastener driving machines e.g. Nail driving tools
  • the impact buffer is axially loaded by the impact piston of the Be fixative-driving device an evasive movement of the elastic material instead, which leads to a surprising increase in life.
  • a preferred embodiment of the bump buffer provides that the slots run alternately in the direction of the inner or outer surface of the jacket. In this way, a uniform loading of the buffer is achieved.
  • the slots open into the inner or outer surface of the jacket.
  • the slots extend over the entire or essentially the entire axial length of the bores, since this also achieves excellent flexibility of the buffer.
  • the slots run radially or essentially radially.
  • Another advantageous embodiment of the invention provides for the same purpose that the bores are each at the same distance from one another.
  • the ratio of the diameter of a bore to the width of a slot is expediently about 2: 1, so that the bounce buffer still has sufficient stability.
  • the bores equipped with slots opening into the inner surface of the jacket open into recesses opening into the upper area of the outer surface. This embodiment facilitates the production of the bores with slots.
  • the upper inner edge of the through opening is rounded.
  • the upper area of the elastic material is spread slightly, which is easily possible due to the slots.
  • the slots opening into the inner surface of the jacket advantageously open into the impact surface. The same applies to the slits opening into the outer surface of the jacket.
  • the outer surface of the casing is advantageously convexly curved in the area adjacent to the impact area.
  • the bump buffer 1 shown which consists of elastic material such as polyurethane, has a central through opening 2.
  • slots 6 run alternately in the direction of the inner surface 4 or outer surface 5.
  • the slots 6 open into the inner surface 4 or outer surface 5 and extend over the entire axial length of the bores 3.
  • the Ver Ratio of the diameter of the bore 3 to the width of the slot 6 is about 2: 1.
  • the slots 6 run radially, the bores 3 each having the same distance from one another.
  • the upper and the lower inner edge of the through opening 2 are rounded.
  • the impact surface 8 and the contact surface 9 are flat, run parallel to one another and perpendicular to the central longitudinal axis M.
  • the slots 6, which open into the inner surface 4 of the jacket, open into the impact surface 8 at their upper end.
  • the impact surface 8 is smaller than the contact surface 9, whereby the outer surface 5 is convexly curved in the area adjacent to the impact surface 8. In this convexly curved area of the outer jacket surface 5, the slots 6 opening into the outer jacket surface 5 open at their upper end.
  • In the lower area of the outer surface 5 of the buffer 1 has a shoulder 10.
