Abstract
To protect a welding and/or cutting burner (10) against damage resulting from its striking against obstacles, the burner is provided with a sleeve (24) having a flange 26 engaging an abutment (28) of a burner retaining device (12) and is rendered, on the one hand, elastically pivotally deflectable about the retaining device (12) and, on the other hand, elastically displaceable along its longitudinal axis (42) by means of a helical spring (36) attached to the retaining device (12) and a ring (34) of the sleeve (24); and moreover the burner (10) is secured against rotation about its longitudinal axis (42) by means of a peg (32) which is fast with the sleeve (24) and disposed between two pegs (30) fast with the retaining device (12). Switches in a gap (40) between the retaining device (12) and the sleeve (24) provide for braking of burner drive motors in the event of large deflection. <IMAGE>
Description
SPECIFICATION
Apparatus comprising welding and/or cutting burner with an associated retaining device
The invention relates to apparatus comprising a welding and/or cutting burner with an associated retaining device.
On the one hand, a rigid retaining device is required for such burners, so that, once adopted, the welding or cutting adjustment does not become disarranged; on the other hand, a flexible retention is desirable, since despite the greatest possible care it happens during operation of such burners, for example in the case of underwater cutting with plasma burners, that the burners butt against an obstacle, and if they are retained inflexibly this results in an increased degree of damage to the burner.
These contradictory requirements are taken into account, in practice, by weighing the demands made on such burners in terms of their operational importance, and the result of this is usually that a flexible retaining device is preferred to an inflexible one and the time delays occurring as a result of readjustment of the burners must necessarily be allowed for in the production cycle.
The object on which the invention is based is to design burners in such a way that, on the one hand, damage to these is very largely avoided in the case of collisions with obstacles and, on the other hand, there is no longer any need for readjustment of the burning or cutting position of the burners.
This object is achieved, according to the invention, by means of the characterising features of the main claim.
Developments of the invention are indicated in the sub-claims.
The advantage achieved by means of the invention is especially the increase in economy of use of welding and/or cutting burners in operation.
An exemplary embodiment of the invention is illustrated in the drawing and described in more detail below. In the drawing:
Figure 1 shows a side view of an apparatus according to the invention.
Figure 2 shows a plan view of the apparatus of Fig. 1, with the burner removed, and
Figure 3 shows a sectional representation along line A-B of Fig. 1.
Referring now to the Figures, there is shown an apparatus comprising a burner 10 (represented symbolically) which is guided by means of a retaining device 12 over a workpiece (not shown) to be welded or cut. The retaining device 12 has an annular plate 14 which is fastened to a flame-cutting machine (not shown) via shaped angle pieces 16, 18 and screws 20, 22.
The burner 10, which projects through orifice 15 in the annular plate 14, is surrounded by a sleeve 24 having an annular web 26.
This web 26 rests loosely on a shoulder 28 of the annular plate 14. Since the sleeve 24 and consequently the web 26 are arranged fixedly on the burner 10, the burner 10 also rests loosely on the plate 14.
As soon as the burner 10 is pivoted out of its normal position, the sleeve 24 surrounding it is also pivoted with it. During this tilting movement, a partial region of the web 26 therefore loses touch contact with the annular plate 14.
Two round pegs 30 project vertically upwards from the plate 14 which is, as a rule, fastened horizontally to the flame-cutting machine. These pegs leave free between them a clearance through which projects a round peg 32 projecting horizontally from the web 26.
Since the intersecting pegs 30, 32 touch one another only slightly the burner 10 can pivot in its longitudinal direction, without the pegs 30, 32 preventing it from doing this. Because, in any position ot the burner 10, the peg 32 is framed laterally by the two pegs 30, the burner 10 cannot rotate about its longitudinal axis. The pegs 30, 32 have such a length projecting freely from the plate 14 that even in the case of extreme pivoting of the burner 10 out of its longitudinal direction or maximum displacement of the burner in its longitudinal direction the peg 32 is positioned, as before, between the two pegs 30.
The sleeve 24 has a bracket 34 at its lower end facing the workpiece (not shown) to be machined. Between this bracket 34 and the plate 14, the sleeve 24 is surrounded by a helical spring 36. This helical spring 36 is fastened to the bracket 34 and to the plate 14. On the one hand, this ensures that the burner pivots back into its normal position again from a pivoted position, since the turns of the helical spring 36 which are compressed on one side and extended on the other side endeavour to assume their normal pitch and consequently their normal position. If the burner is struck from below in its longitudinal direction, the bracket 34 fastened to it by means of the sleeve 24 is also displaced upwards in the direction of the plate 14.The helical spring 36 is compressed as a result, so that the impact with which the burner 10 strikes, for example, against a workpiece to be machined is alleviated.
The arrangment of the helical spring 36 therefore ensures that the burner 10 always moves into its normal cutting or burning position again, whether it is struck from the side or from below.
The orifice 15 in the annular plate 14 widens conically from the top downwards, so that a gap 40 remains between lower edge 38 of the orifice 15 and the outer surface of the sleeve 24. The free pivoting movement of the sleeve 24 and consequently of the burner 10 in its longitudinal axis 42 becomes possible as a result of this gap 40. The maximum possible deflection of the burner 10 is predetermined by the size of the gap 40.
Deflection of the burner is caused, for example, because the burner 10 strikes against an obstacle located laterally next to it.
This can occur either as a result of a travelling movement of the burner carriage, a travelling movement of the flame-cutting machine or a combined travelling movement of the burner carriage and flame-cutting machine. By means of switches which are built into the gap 40 and which are activated in the event of appropriately large deflecting movements of the burner 10, the drive motors of the burner carriage and flame-cutting machine can be stopped in good time as a result of quickacting brakes, so that the burner 10 does not strike against the lower edge 38. This prevents the burner 10 from encountering an obstacle laterally without damping and from possibly being damaged as a result.
