Definitions
- the invention relates to a chisel, in particular round shank chisel, with a chisel head and a chisel shank, wherein in the region of the chisel shank a fastening sleeve is held, and with a support member having a guide portion.
- the fastening sleeve is designed as a clamping sleeve, which is formed from a resilient material, such as steel sheet. It has a longitudinal slot which is bounded by sleeve edges.
- the longitudinal slot of the mounting sleeve diameter can be varied, with the sleeve edges to move toward each other (small diameter) or spaced from each other (large diameter sleeve). In this way, different clamping states can be achieved.
- On the mounting sleeve which is designed as a wear protection disc Mounted supporting element. This support member has a circular cross-section and is penetrated by a bore.
- the bore is dimensioned such that the fastening sleeve is held in a bias state with reduced outer diameter relative to its relaxed state.
- the outer diameter thus produced is selected such that the clamping sleeve can be inserted with little or no effort in a bit holder of a chisel holder.
- the insertion movement is limited by means of the support element.
- the support member Upon further insertion of the drill collar in the bore, the support member is moved in a non-covered by the clamping sleeve portion of the drill collar. Then, the fastening sleeve jumps radially and clamped in the bore of the chisel holder.
- the round shank bit is axially captive, but freely rotatably supported in the circumferential direction.
- To disassemble the chisel it is driven out of the chisel holder by means of a dome which acts on the back of the chisel shaft.
- a wear shield is also used as a support member which holds the mounting sleeve in a bias state.
- the support element can be moved in the direction of the bit head until the mounting sleeve rebounds radially. Then, the support member engages with projections in receptacles of the mounting sleeve, whereby a non-rotatable mounting between the mounting sleeve and the Support element arises.
- Such non-rotatable bearings have proven to be disadvantageous because they cause increased and uneven wear.
- a chisel in which a support element can likewise be pushed off a fastening sleeve.
- the support element comes to lie between the chisel head and the free end of the mounting sleeve.
- the support member has on its side facing the mounting sleeve on a circumferential projection.
- the support element has a deflection section in the region of its underside facing away from the bit head.
- the fastening sleeve When dismantling the bit from the bit holder, the fastening sleeve can be brought into operative connection with the deflection section. As a result, the fastening sleeve is brought into the fastening sleeve section formed by the guide region.
- the mounting sleeve is then again in a clamping state that allows easier removal of the bit from the bit holder.
- this clamping state then also makes it possible to use the chisel for reuse without or with little effort in a chisel holder.
- the bit for the initial assembly is already configured such that the guide portion holds the mounting sleeve in a clamping state.
- the fastening sleeve can be moved by means of the deflection section from a relaxed position into a clamping position. This is advantageous, for example, if the support element is removed from the fastening Retaining sleeve was unintentionally deported and is in his chisel head facing working position. Then, by means of the deflection section, a mounting position can easily be restored by pushing the support element onto the fastening sleeve.
- the deflection section can also serve to bring the fastening sleeve from a partial clamping position into a clamping position.
- the partial clamping position is usually present when the bit is mounted in the bit holder and acts with a residual clamping force on the bore wall of the bit holder.
- a conceivable variant of the invention is such that the support element has an insertion region which is indirectly or directly transferred into the deflection section.
- the fastening sleeve can then be threaded into the insertion region with a section facing the support element and brought into the deflection section via the latter. It has proved to be particularly advantageous if it is provided that the fastening sleeve has a guide which is held in the region of the insertion. Then a spatial assignment of the mounting sleeve is already made in the mounting position to the support element.
- mounting sleeve and support element Due to this overlap between mounting sleeve and support element creates a labyrinth-like closure, which reduces the risk of ingress of dirt. In this way, the rotational behavior between the bit and the support element is improved. It is also conceivable that the guide is in the axial direction of the bit at a distance from the insertion. Then, the insertion should be dimensioned so that the leadership of the mounting sleeve can be reliably inserted during disassembly. In particular, wear-related deformations, for example, of the fastening sleeve in its region facing the support element are also to be taken into account.
- a particularly preferred embodiment of the invention is such that a centering section is arranged in the transition area of the bit head in the bit shaft, which is formed on its outer periphery such that it forms a pivot bearing together with the guide region.
- the pivot bearing allows that Support member can rotate independently of the mounting sleeve. This achieves a wear-optimized design of the entire chisel.
- this pivotal mounting results in a centered alignment of the bit with respect to the support element, which leads to the improvement of the milling result and to the reduction of rotary wear.
- a chisel according to the invention may be such that the support element has on its upper side facing the chisel head an importer extension which merges directly or indirectly into the guide region.
- This introducer upgrade simplifies the initial assembly of the bit. First, the mounting sleeve is placed on the drill collar. Then, the support member is pushed onto the relaxed mounting sleeve, the Ein mecanicweittation serves as Einfädel Anlagen.
- a particularly simple construction results from the fact that the guide region and the insertion region are each formed by a bore, and that the bore forming the insertion region has a larger diameter than the bore forming the guide region.
- the recess and the facing portion of the bit head form a labyrinth-like closure which impedes the penetration of space material. In this way, a good rotation of the bit over the remains Support element received. It has been found that it is disadvantageous when the support member relative to the chisel holder is fixed against rotation, since this can then work unevenly due to impact stresses in the facing bearing surface of the chisel holder. For this reason, a relative mobility of the support element relative to the bit holder should be maintained. To ensure this, the support element is provided at its radially outer peripheral region according to a variant of the invention with recesses. These recesses form attack areas for removed space material, which then introduces a circumferential force into the support element.
- a centered alignment of the support member relative to the bit holder can be achieved in that the support member has on its underside a projecting spigot. This can intervene in a centering of the chisel holder. Between centering and centering a kind of seal is again formed, which prevents penetration of space material.
- a further wear-optimized chisel design is achieved when it is provided that the centering projection has a centering surface inclined to the central longitudinal axis of the chisel, which merges via a set-back recess into a peripheral seat surface running radially to the central longitudinal axis.
- the recessed recess forms a kind of stress relieving throat. In addition, this recess exposes the associated edge region of the chisel holder, which leads to an improved free rotation.
- An inventive chisel may be characterized in that the fastening sleeve has one or more holding elements which engage in a circumferential groove of the chisel shank to form a rotary bearing. In this way, the free rotation of the bit with respect to the fastening sleeve in the circumferential direction is guaranteed. It is particularly advantageous if it is provided that the holding elements are separated from the mounting sleeve along two, extending in the circumferential direction, separating edges, and that the separating edges of the holding elements in each case opposite the groove side walls of the groove. The holding elements can be very accurately punched out of the sleeve material and tuned to the groove width.
