Definitions

  • the invention relates to a flat chisel according to the preamble of claim 1.
  • Such flat chisels come when processing rock, especially masonry to use, for example Create breakthroughs, channels and slots. From a standing start Flat chisels are known in the art, their main cutting edge is arranged transversely to a chisel longitudinal axis and one has a straight course (see Fig. 1). such Flat chisels tend to do this while working the rock or when reattaching, along the course of the To move the main cutting edge away from the desired position.
  • the invention has for its object a flat chisel to develop, which has a low tendency from a specified position laterally, along the cutting edge emigrate. Furthermore, it is a side task Jamming of the flat chisel in the rock to be processed counteract.
  • the flat chisel according to the invention has a main cutting edge and / or a side surface designed as a side cutting edge on which is a concave and / or convex and / or have a bent course.
  • a side cutting edge designed as a side cutting edge on which is a concave and / or convex and / or have a bent course.
  • Through the sickle or wedge-shaped course of the main cutting edge engages this almost every surface shape of the material to be processed at first approximately point-like and centered on it thereby in the specified position. This works for you Migration or slipping of the chisel out of the targeted one Working position opposite.
  • In the area of the side faces is through the formation of side cuts with a protruding or recessed course of the Cutting edges a full surface contact of the side edges avoided.
  • a flat chisel is a chisel with an elongated one Understand cutting edge, which is essentially perpendicular to a chisel longitudinal axis or transverse to a direction of impact runs.
  • the subject of the invention goes into at least one side cutting edge the main cutting edge over. This is a cutting edge-free Avoided area where the chisel jammed the material to be processed can come. Moreover the cutting edges stabilize each other.
  • the main cutting edge and / or side cutting edge is the flat chisel for a wide variety of applications and angles suitable.
  • FIG. 1 shows a chisel known from the prior art 1 'shown, which is designed as a flat chisel 2 and itself essentially from a chisel head 3, a chisel shank 4 and a clamping shaft 5 or insertion end.
  • the clamping shaft 5 is a so-called SDS-Plus clamping shaft 6, which for coupling power drill and chisel hammers.
  • such Chisels are also known as insert chisels.
  • At the Chisel head 3 is perpendicular to a chisel longitudinal axis x one Main cutting edge 7 arranged, which over a front Cutting surface 8 and a rear cutting surface 9 in one front face 10 and rear face 11 transforms.
  • Connect side surfaces 12, 13 of the chisel head 3 the striking surfaces 10, 11.
  • FIG. 2 shows a partial view of an inventive Chisel 1, which is designed as a flat chisel 2.
  • Flat chisels 2 are only one chisel head 3 and part of a chisel shank 4 shown.
  • the chisel head 3 has a main cutting edge 7 with a intersecting cutting surfaces 8, 9 formed Cutting edge 20 on. Close to the cutting surfaces 8, 9 face 10, 11, which in one Transition area 19 into chisel shank 4.
  • the Cutting edge 20 is concave to a not shown Shank.
  • the main cutting edge 7 forms a kind of sickle 24, which ends in peaks 25 and in a low 26 of a chisel longitudinal axis x is cut.
  • the main cutting edge 7 goes in side cutting 14, 15 with cutting edges 17, 18, which are also concave are formed and towards the chisel longitudinal axis x run bent.
  • FIG. 3 shows a top view of the one in FIG. 2 illustrated flat chisel.
  • this is in one Side view shown from the right.
  • Cutting surfaces 16 one Side cutting edge 14 does not fork in the direction of one shown clamping shaft.
  • a cutting edge 17 of the Side cutting edge 14 thus divides in a lower area 27 in two cutting edges 17a, 17b.
  • the cutting edge 17 and the main cutting edge 20 lie in a common plane E.
  • FIG. 5 shows a top view of the one in FIG. 4 illustrated flat chisel.
  • FIG. 6 shows a partial view of a second chisel 1 or Flat chisel 2, of which only one chisel head 3 and part of the Chisel shafts 4 are shown.
  • flat chisel runs a main cutting edge 7 or their cutting edge 20 concave and forms a kind of sickle 24.
  • the sickle 24 is symmetrical about a longitudinal central axis x the flat chisel 2 aligned and runs in side surfaces 12, 13 out.
  • the main cutting edge 7 ends in tips 25. To the Side surfaces 12, 13 have no side cutters.
  • FIG. 7 shows a top view of the one in FIG. 6 Flat chisel 2 shown.
  • the flat chisel 2 has a Chisel shank 4 with a circular cross section A.
  • FIG. 8 shows a side view from the right of the one in FIG 6 shown flat chisel 2.
  • Figure 9 shows a plan view on the flat chisel 2 shown in FIG. 8.
  • FIG. 10 shows a partial view of a chisel 1 or Flat chisel 2, of which a chisel head 3 and part of the Chisel shafts 4 are shown.
  • a main cutting edge 7 or the cutting edge 20 are V-shaped. Cutting surfaces 8, 9 of the main cutting edge 7 are along one Chisel longitudinal axis x through a separating edge 28 in Partial cutting surfaces 29 separated. At the transition of the main cutting edge 7 to side surfaces 12, 13 tips 25 are formed.
  • FIG. 11 shows a top view of the one in FIG. 10 illustrated flat chisel.
  • Figure 12 shows a side view from the right onto the flat chisel 2 shown in FIG. 10.
  • FIG. 13 shows a top view of the one in FIG. 12 Flat chisel 2 shown.
  • FIG. 14 shows a main cutting edge 7 of no further shown flat chisel 2.
  • the main cutting edge 7 is in Cross section or viewed from the side as ramp 24 formed and has a parallel to a longitudinal axis of the chisel x cutting surface 9 and an oblique to this extending side surface 8. According to one, not illustrated embodiment, it is also provided that Form side cutters in a ramp shape.
