Definitions

  • the invention relates to a bending device positionable for bending a sheet in a gap between two blade rings arranged along an axis of a compressor or turbine with blades extending along a radius. Furthermore, the invention relates to a method for bending a sheet in the intermediate space.
  • a turbine or a compressor formed between a housing and an impeller or rotor flow channel with a flow of working fluid is applied.
  • the flow channel extends along an axis of the compressor or turbine.
  • In the flow channel extend along a radius blades, which are flowed through by the working medium.
  • These may be casings attached to the housing or blades attached to the impeller or rotor.
  • the vanes serve to influence the flow of the working medium.
  • the blades are flowed by the flow of the working medium.
  • the blades are rotated by the impeller in rotational motion and compress in this way the flow of the working fluid.
  • the flowing working fluid releases its kinetic energy to the blades, which in this way cause the rotor to rotate.
  • the rotational movement of the rotor can be used, for example, to drive a generator and above to generate electricity.
  • a number of vanes typically form a vane ring in which the number of vanes are secured annularly juxtaposed along the circumference of the flow duct to the housing in the case of vanes or on the rotor or impeller in the case of blades.
  • One depending on the application appropriate number of such blade rings is arranged in steps along the axis of a compressor or a turbine in a row.
  • the design and alignment of a blade of a blade ring varies from stage to stage in accordance with the pressure and temperature conditions of the flow of the working medium along the flow channel. Between a first and a second blade ring arranged along the axis, there is a gap in which the medium flows freely.
  • a shovel In the space a shovel is fixed with its foot on the impeller or housing.
  • the attachment can be secured by bending a metal sheet in the intermediate space, for example into a gap formed on the housing or impeller or rotor.
  • a compressor For assembly or disassembly during production or revision of a compressor such a locking plate is previously bent manually.
  • a bending tool in the form of a rod or a suitable lever is positioned in a space between two blade rings arranged along an axis of a compressor with blades extending along a radius on the sheet to be bent. By striking a hammer on the bending tool, the sheet is then bent manually.
  • This bending process must be performed individually for each locking plate.
  • the manual activity no defined and reproducible bending in a series of sheets can be guaranteed.
  • the manual operation leads to a relatively high installation time.
  • the leverage forces to be executed are in some cases so great that when the lever slips off there is a comparatively high risk of injury to the installer and / or a blade of the compressor can be damaged.
  • the impeller or provided for receiving the blades wheel disc can be damaged.
  • cracks can be initiated in the metal sheet due to undefined, manual bending which may affect its life and safety.
  • the situation is similar in a bending operation of a sheet in a gap in a turbine.
  • a stationary device is known from US Pat. No. 3,440,706, by means of which compressor rotor blades can be fastened to a rotor disk.
  • the blades are arranged on the rotor disk and fastened by means of a then protruding sheet metal strip.
  • a plurality of hydraulic punches are present on the device. These hydraulic rams are extended one after the other and retracted to gradually bend over the sheet metal strip until it rests against the rotor disk on the front side.
  • the invention is directed to providing an apparatus and method for bending a sheet in a space between two blade rings arranged along an axis of a compressor or a turbine with blades extending along a radius which simultaneously perform the bending operation more effective and reliable than a manual bending process.
  • the object is achieved by the bending device mentioned above, which according to the invention comprises a fixing element for the bending device, a hydraulic system and an actuatable by the hydraulic punch, which is executable in the direction of the radius.
  • the invention is based on the consideration that, in departure from a manual bending process, a comparatively automated bending process can perform, on the one hand, more effectively and, on the other hand, more reliably the bending of a metal sheet.
  • the invention has recognized that it is possible to provide a bending device which is fixable in the intermediate space and can bend a sheet to be bent in a defined manner effectively and reliably via a hydraulically actuable punch.
  • the hydraulics can namely be operated largely automatically, without a fitter would have to perform manually with an attached lever bending the sheet. Rather, it is up to the installer now to fix the bending device in the space and to set the hydraulics in motion.
  • the method according to the new concept leads to a time saving when bending a sheet, so that in particular in the case of a compressor, the possibility of a comparatively rapid exchange of a blade ring is given. In this way the revision time and thus the necessary costs are reduced. Since a fitter no longer has to carry out the bending process independently with considerable expenditure of force, a danger of injury to the fitter and a risk of damaging a blade are virtually ruled out. Rather, an installer adjusts and fixes the hydraulic bending device and then activates the hydraulics. The installer can observe the bending process and possibly influence the bending process under control of the hydraulic and hydraulic power.
  • the bending device is expediently formed in the form of a mobile, portable bending device.
  • the bending device can be handled easily and, for example, along the axis of a compressor in each successive spaces each properly positioned and fixed.
  • the fixing element is designed for fixing the bending device in the respective intermediate space along the axis.
  • This has the advantage that the bending device can be properly fixed with varying dimensions of the intermediate space, for example with a varying dimension between a first and a second blade ring, ie even in the case of a variable environment.
  • a fixing element in the form of a clamping element that allows clamping of the bending device in the intermediate space along the axis is particularly advantageous.
  • the fixing element is adaptable to different spaces between the blade rings.
  • the hydraulic system of the bending device preferably has a pump, a guide for hydraulic fluid, for example an inlet and outlet, and a cylinder for actuating the punch.
  • the hydraulic pump is replaceable.
  • the bending device in particular has a variable connection, via which a pump can be connected. This can be, for example, any automatic pump, eg a pump that is often present for an embossing device, or a manually operated hand pump. This has the advantage that the bending device can be operated with existing pumps.
  • the punch of the bending device is replaceable.
  • This increases the variability of the bending device and makes the bending device adaptable, for example, to a respective plate of a compressor wheel.
  • the bending device can thus be used for a variety of spaces with variable dimensions. Despite different dimensions of the spaces along an axis of a compressor or a turbine thus one and the same bending device for bending a sheet can be used in a space, namely by, for example, the fixing element for clamping the bending device is variably adjustable and on the other hand a stamp of the bending device is replaceable, in particular by a stamp of other dimensions is replaceable.
  • the punch is extendable in the direction of the radius.
  • the ram in the case of a bending device fixed along the axis of a compressor or a turbine, the ram can therefore be extended perpendicularly to the fixing direction of the bending device, namely in the direction of the radius. It has been found that a bending device arranged in this way relative to a turbine or a compressor can be adjusted and fixed in a particularly simple and reliable manner and can execute the bending operation reliably.
  • the bending device is fixed in the space along the axis and the punch in the direction of the radius moved toward the sheet to be bent. Conveniently, the sheet is folded into a groove of the impeller.
  • FIG. 1 shows an impeller 1 of a compressor (not shown) with a number of blade rings 5 arranged along an axis 3 of the compressor.
  • a blade ring 5 has a number of blades 9 extending along a radius 7, of which in each case one blade 9 in FIG Section is shown.
  • a blade 9 of the compressor is held with its foot 11, similar to a tongue and groove connection to a respective segment 13 of the compressor wheel 1.
  • the groove for receiving the foot 11 is in each case designed as an axial groove.
  • the orientation and design of such grooves is exemplified in FIG 2, wherein the arrow 12 indicates the direction of the turbine axis 3.
  • the foot 11 is inserted together with an underlying plate 47 in the groove of the segment 13.
  • sheet 47 is provided with a bead 14 running circumferentially (i.e., transverse to axis 3) which engages a corresponding recess on the underside of foot 11.
  • the length of the sheet 47 is dimensioned such that it projects beyond the impeller 1 or the so-called wheel disc head immediately after insertion into the groove of the segment 13 on both sides (that is, in the axial direction). This is shown in FIG. 3A.
  • the arrangement of the plate 47 which acts as a safety plate in this manner after bending (that is to say in the operating state of the compressor) is shown in FIG. After bending into the respectively provided for receiving groove 43, the tabs of the plate 47 are flush with the wheel disc head.
  • the position of the locking plates 47 in relation to the turbine blades 9 and the Radusionnkopf can also be illustrated by the reproduced in Figure 4 view, in which the viewing direction in the radial direction (from the blade tips to the turbine shaft) is selected.
  • a plate 47 is shown before bending and a plate 47 after bending.
  • the respective receiving groove and thus also the plate 47 are slightly inclined in this example against the direction of the axis 3.
  • a bending device 17 is fixed.
  • the bending device 17 is positioned in the intermediate space 15 and clamped by a fixing element 19 in the form of a clamping element in the intermediate space 15 between two stops 21 of adjacent segments 13 of the compressor wheel 1.
  • the fixing element 19 can be widened via a screw 23 or alternatively via a hydraulic cylinder.
  • the fixing member 23 is mounted either releasably adjacent to the bending device in the space 15 and by actuation of the screw 23 or hydraulic Widened way.
  • the fixing element can also be attached directly to the bending device and already positioned with the bending device in the intermediate space 15. In this way, the bending device 17 together with the fixing element 19 have different axial widths, which is also adaptable to a gap 15 'or 15 ", wherein the intermediate spaces 15, 15' and 15" have different dimensions.
  • a bending device 17 fixed in this way also has a hydraulic system 25.
