Definitions
- the invention relates to a lance, in particular a rotary lance, for deburring and / or cleaning workpieces. Specifically, the invention relates to the field of high pressure rotary lances used for deburring channels having transverse bores and / or openings in workpieces.
- An object of the invention is to provide a lance with an improved mode of action.
- a medium under high pressure can form a fluid flow according to the invention, wherein the medium is, for example, under a pressure of more than 30 MPa (300 bar).
- At least one (with respect to a feed direction of the lance and / or a direction of rotation of a lance portion) forward and / or a rearwardly directed nozzle is provided on the nozzle portion, over which the feasible to the nozzle portion medium can be emitted beam-shaped.
- a forward and / or a backward nozzle on the one hand, an advantageous jet can be formed, which achieves a high degree of effectiveness on impact for removing or detaching the burr.
- lateral irradiation of the burr can be achieved, so that the burr is hit by the beam on its side surface, resulting in a large detaching force.
- At least one laterally directed nozzle is provided on the nozzle section, via which the medium which can be guided to the nozzle section can be emitted in a jet-like manner, and / or at least one tangentially directed nozzle is provided on the nozzle section via which the nozzle can be guided to the nozzle section
- Medium jet-shaped can be issued, and / or that a further tangentially directed nozzle is provided, via which the feasible to the nozzle portion medium jet is deliverable, and that the further tangentially directed nozzle is aligned with respect to a direction of rotation opposite to the tangentially directed nozzle.
- Side-facing nozzles preferably each have an outlet direction, which is oriented transversely to the feed direction of the lance and / or transversely to a lance axis.
- Tangentially directed nozzles preferably each have an outlet direction which is oriented at an acute angle to a cylindrical circumferential surface of the lance and in a surface perpendicular to a lance axis.
- the medium can be emitted in a jet, which has a high Entgratungsfensiv when hitting.
- the beam can be directed to the ridge in an advantageous direction (according to its outlet direction).
- a cross section, in particular a circular cross section, of the nozzle section of the lance can be adapted to the cross section of the channel, so that the medium issuing from the tangentially directed nozzle in a jet-like and tangential direction is deflected by the channel wall in the direction of the ridge and an advantageous Deburring takes place.
- At least one inclined forward or backward nozzle is provided, which is at least partially aligned against the lateral orientation of at least one sideways or tangentially directed nozzle.
- a transverse force which is generated in particular by the laterally or tangentially directed nozzles in the case of longer lances, can be increased. At least partially compensated, whereby an undesirable deflection of the lance can be reduced or prevented.
- the tangentially directed nozzle is aligned with an outlet direction at least substantially in a circumferential direction.
- the medium With respect to an outer wall of the nozzle portion, the medium thereby exits the nozzle as flat as possible on the outer wall, so that a substantially aligned in the circumferential direction of the jet results.
- An angle to the outer wall of the lance is preferably less than 30 °. In this way, the beam can be directed at a favorable angle to the ridge, the beam in particular hits the ridge laterally and thus not only the optionally very narrow side of the ridge is hit. Thus, the effect of the jet incident on the burr can be further improved.
- At least one storage space for the nozzle is formed in the nozzle section.
- the efficiency of the nozzles provided in the nozzle section can be further improved. Specifically, in a rapidly flowing fluid, an advantageous increase in the efficiency can be achieved.
- the storage space is delimited by at least one storage area which is oriented at least substantially counter to a flow direction of the medium which can be guided through the conduit and / or if the storage space at least partially extends into a wall of the nozzle portion.
- a storage area oriented counter to the flow direction, an advantageous stowage of the fluid for the nozzles adjacent to the storage space in the nozzle section can be achieved.
- a further improvement in the efficiency can be achieved, for example, for tangentially directed nozzles which open into the storage space.
- an inlet for the nozzle is formed in the nozzle section. Such an inlet is especially advantageous for a forward or reverse nozzle to further enhance the effect. This can be advantageously combined with a storage space for laterally or tangentially directed nozzles.
- the inlet for the nozzle is designed as at least partially conical inlet and / or that the inlet is provided for a forwardly directed nozzle.
- Both the conical design of the inlet and the design of the nozzle as a forward nozzle are aerodynamically advantageous because turbulence or separation of the flow can be prevented or at least reduced.
- the nozzle section is provided at a tip of the lance. As a result, an advantageous arrangement of a plurality of nozzles on the nozzle portion is possible. In addition, a larger number of nozzles can be realized even at a relatively small peak. It is also advantageous that a forward nozzle is oriented at least approximately on a longitudinal axis of the nozzle section. As a result, during the introduction or passage of the lance through a channel or the like, a beam directed in the forward direction can be generated. Especially in combination with laterally or tangentially directed nozzles, existing burrs can be made for deburring from different directions, so that extensive deburring is possible.
- a burr is first processed from one direction and then in the further rotated state of the lance from another direction. This bends the burr back and forth, so to speak, so that the burr breaks off and is thus removed.
- the nozzle is configured by at least one nozzle bore formed in the nozzle section. As a result, a compact configuration of the nozzle portion of the lance is possible. In addition, a high mechanical strength of the nozzle is possible.
