Definitions

  • the invention refers to a tool, such as a drill bit or chisel, which is associated with an impact tool, such as a drill bit or chisel, which is at least partially hammering, such as a drill or chisel, preferably for working stone such as concrete and masonry.
  • a used as a tool drill bit is claimed by an at least partially hammering hammer, for example.
  • the striker and / or the flying piston of an electro-pneumatic striking mechanism With the striker and / or the flying piston of an electro-pneumatic striking mechanism, axially to the tool axis with mechanical shocks on the end face of the insertion, wherein the impact energy substantially via longitudinal pulses in shape propagates from shock pulses to the opposite end face and allows the output of the material to be machined energy editing.
  • This opposite end face is usually designed as a carbide-tipped tool head.
  • US4165790 is a tool in a plurality of non-rotatable and limited axially movable parts, eg. In a short tool head, a much longer tool shank and a spigot, divided, each one secured with a cross pin hexagon connection forms the form-fitting rotationally fixed and limited axially movable connection.
  • US4605079 has a very short such tool head on a hexagon socket for a form-locking rotationally fixed and limited axially movable connection.
  • Such tool heads are not optimized with respect to the momentum transfer.
  • WO97 / 08421 there is a drill bit at the end of a drill pipe or a drill rod, wherein the form-locking rotationally fixed and limited axially movable tool head itself forms a head part and a shaft part with respect to an arranged within its axial length face.
  • the non-rotatable fixation via polygonal shaped cross-sectional areas or via engaging in recesses noses.
  • About a light metal pin or a ring of the tool head is limited axially movable axially fixed to the drill pipe or the drill rod.
  • the ratio of the lengths of the shank part with respect to the head part is as large as possible, in particular greater than five, so that the maximum pulse energy can be transferred to the tool head for machining the material.
  • a certain impedance ratio of the shaft part to that of the head part is to be observed, wherein constructive, slight axial variations of the absolute values are permitted.
  • the US1744141 discloses a tool adapted for processing rock by an associated percussion impact tool, wherein the shank of the tool abuts with a convex and the percussion means with a concave crowned face.
  • the object of the invention is to optimize the transmission of the pulse energy applied by the impact tool in the tool head of a structurally simple to manufacture tool. Another aspect is a suitable attachment of the tool head of such a tool.
  • a tool with an acoustically long tool shaft rotatably connected and axially limited movable tool head with respect to its impedance acoustically matched to the flying piston and / or the striker of the striking tool device, each abutting faces respectively at least partially flat in contact with each other.

  • an end face is advantageously crowned concave and the associated end face convexly convex.
  • an infinitely large effective contact radius would be ideal, with approximately 25% of the increase in processing power being lost in the case of a practically realizable effective contact radius of more than 1 m, compared to an ideal areal contact.
  • the material of the flying mass of usually steel for example, can be advantageously substituted into a light ceramic or carbon fiber composite material.
  • Necessary constructive embodiments of tool head, flying piston and / or striker must be based at least substantially on such a geometry without being strictly prismatic. In the case of real deviations of approx. 10% each, approx. 25% of the increase in processing capacity is lost.
  • the tool itself consists of a tool shank and a rotatably limited axially movable tool head with cutting edges of hard material, the tool shank acoustically long and the tool head is acoustically tuned to the flying piston and / or striker.
  • striker tool shank and tool head whose cross sections are the same.
  • the coupling region of the tool shank adjacent to the tool head is advantageously of prismatic design, the cross section advantageously having the shape of a regular polygon, for example a hexagon.
  • the edges are advantageously broken over a chamfer.
  • the tool head which forms the matching prismatic counterpart, is fastened in a rotationally form-fitting manner via the connection that forms as a result.
  • a guided transversely to the tool axis both through the tool head and through the tool shaft pin provides a fixation means in conjunction with an axial slot in at least one of the parts a smooth, limited axial mobility safely.
  • the tool shank is made hollow, wherein a fluid medium such as rinsing liquid can be passed through the channel formed.
  • the channel has inlet and outlet openings at the insertion end and in the tool head, wherein a limited axially movable, advantageously annular, sealing element is advantageously arranged between the tool shank and the axially movable tool head limited.
  • the tool head which is acoustically matched with respect to its length and its cross section, is provided with a sleeve-like region assigned to the tool shank, in which the tool shank engages in a rotationally fixed and limited axially movable manner.
  • the necessary, at least in part essentially planar design of the end face between the tool shank and the tool head is realized via an inner annulus area with a very large effective radius of curvature.
  • An optional sealing element is advantageously designed as a radially smaller, centrally offset part of the tool shank, which ends in a central bore in the cutting edge region of the tool head, of which at least one opening leads to the end face of the tool head, which advantageously offset eccentrically to the tool axis outside the head groove arranged to clear the abraded material adjacent to the cutting edge.
  • a fixing means is a transversely through an axial slot of the sleeve-like portion of the tool head and through a hole in the tool shaft guided pin.
  • the tool head which is acoustically matched with respect to its length and cross section, is provided with a radially smaller, centrally offset region associated with the tool shank with a driving nose arranged in the radially outer, which engages in the tool shank in a rotationally fixed and limited axially movable manner.
