Definitions

  • the invention relates to an impact tool for comminuting materials, in particular of wood waste, with a shank and a chisel head, wherein the chisel head a cutting insert is attached.
  • Such a striking tool is known from DE 35 45 708 C2. That's one circulating Schlegel described on the body a releasably connected Cutting body is attached.
  • the cutting body is as a tooth with a shaft educated.
  • the shaft carries one of a recess of the einschwenkbar mounted main body generally longitudinally projecting cutting head of essentially triangular cross-section which determines the cutting edge.
  • Surface of the cutting head is defined a predetermined breaking point at which the Cutting head in case of overload, for example by stones or other hard ones Objects, at a predetermined point breaks.
  • the predetermined breaking point is set in this way, that the remaining part of the cutting head before the shaft and its holder Damage protects.
  • a cutting body with extended life is described in G 93 05 835.7 described.
  • the cutting body is essentially as a casting with a formed parallel to the axis of rotation extending cutting edge, wherein the Cutting edge a plurality of juxtaposed carbide body parts as Wear body has.
  • the object of the invention is achieved in that the cutting insert at least a first and at least one second cutting element and that the first and second cutting elements are arranged one behind the other in the cutting direction.
  • Front cutting elements is a downstream cutting element available, which both the cutting tasks as the mechanical protection of the behind lying, insufficiently shock and abrasion resistant chisel head takes over.
  • the cutting insert is constructed to have two or more first ones and / or second cutting elements which are transverse to the cutting direction next to each other are arranged. Due to the resulting lower Dimensions of the cutting elements is the bending load of the individual elements reduced during operation, resulting in a reduced breakage failure. Farther stand in case of failure of a cutting element, the adjacent elements continue to Available.
  • first and / or the second cutting elements plate-shaped and they have two or more teeth side by side transversely to the cutting direction are arranged, improved cutting of fibrous materials such as wood reached.
  • a permanent and dimensionally stable mounting of the cutting elements of the cutting insert At the chisel head is achieved by the fact that the chisel head a recording for the cutting insert, the two at an angle Supporting surfaces, wherein the first support surface is substantially in Cutting direction extends that the first and second cutting elements on this Support surface are supported, that in the cutting direction behind the first Cutting element arranged second cutting element with its back on the second support surface is supported and that the first cutting element on the back supported at the front of the second cutting element.
  • the first and second exist Cutting element made of hard materials of different quality. So the first, in the direction of rotation front cutting element of a higher quality, more resistant material, while the back Cutting element can be made of a less expensive material.
  • a dimensionally stable support of the cutting device while preventing the jamming of the impact tool is achieved by the chisel head a has inclined to the cutting direction inclined free surface, which opposes the Cutting direction connects to the cutting insert and by the first Cutting element is transferred via the second cutting element in the open space.
  • Figure 1 shows a striking tool (10) with a shaft (11) and a so connected chisel head (16) in side view.
  • the impact tool (10) is with a bolt, not shown here, through a mounting hole (12) is guided, attached to a revolving flail, also not shown.
  • a clamping surface (13) also serves to transfer the forces on the flail.
  • the chisel head (16) connected to the shank (11) carries one Cutting insert (20), from the one behind the other in the working direction Cutting elements (21 a) and (21 b) is constructed.
  • the rear cutting element (21 b) is on its back over a support surface (18) and on its underside over a Support surface (17) connected to the chisel head (16), for example, soldered. It can lessen from one compared to the front cutting element (21 a) Material quality to be made, since it is used only in case of failure.
  • the front cutting element (21 a) is on its rear side over a contact surface (22) with the rear cutting element (21 b) and on its underside via a Support surface (17) connected to the chisel head (16), for example, soldered.
  • the front cutting element (21 a) is over the rear cutting element (21 b) without heels in an open space (19) transferred.
  • the open space is opposite to the cutting direction (Feed) arranged inclined.
  • the front cutting element (21 a) is in the range the contact surface (22) like a paragraph over the rear cutting element (21 b) before, so that it passes over a step in the open space (19).
  • FIG. 2 shows the impact tool (10) with respect to the shaft (11).
  • widened chisel head (16) In the shaft (11) is the mounting hole (12) appropriate.
  • the chisel head (16) carries the cutting insert (20), with the front Working surface of two front cutting elements (21 a) is composed, the have a common contact surface (24).
  • Each of the front cutting elements has teeth (23), which improve the crushing performance serve.
  • the teeth are spaced from one another at the same pitch.
  • the front cutting elements (21 a) identically shaped, so that a cost-effective production is possible.
  • To the Rear cutting elements (21b) are also formed teeth (23).
  • the front Cutting elements (21 a) and the rear cutting elements (21b) are so aligned, that the teeth (23) congruent in the direction of rotation arranged one behind the other.
  • the rear cutting elements (21 b) have a common contact surface (24).
  • Figure 3 shows the impact tool (10) from the back in perspective view.
  • the free surface (19) of the chisel head (16) is corresponding to the shape of the teeth (23) of the Cutting insert (20) profiled. This will make the cutting insert effective supported, without that he can get stuck with the crushed material.
  • the Clamping surface (13), the projection (15) and the mounting hole (12) serve the Assembly of the impact tool (10).
