Description

The invention relates to a device for moving and supplying electrical energy to a component, to a method for operating such a device, and to a production system for producing at least one component region of a component which comprises such a device.

In many technical applications, it is necessary to supply moving components or components with electrical power. In particular, this applies, for example, to manufacturing processes and the associated production facilities, which are necessary for their implementation. These production systems can be used, for example, for the purpose of processing, positioning, assembly and / or heat treatment of component materials, component regions or finished components. There are a variety of manufacturing processes known that allow for economic production or processing depending on product complexity, material and anvisierter quantity. In particular, additive manufacturing processes and systems are known which enable the layered construction of components from a shapeless component material. With these methods, for example, plastics, metals or ceramic materials can be processed. Metallic components are produced in particular by means of selective laser melting and / or laser sintering devices. Here, metal powder serves as a component material. In a first step, a layer of defined thickness of metal powder is drawn out onto a substrate plate. Subsequently, surfaces and contours are solidified by means of a laser or electron beam (eg, sintered or fused) according to a virtually sliced CAD model. In the next step, the construction platform is lowered and another layer of powder is raised, which is selectively solidified again. These steps are repeated until the component areas or components are or are completed. Further, various heat treatment methods and heating methods are known, such as electrical resistance heating or radiant heating. Likewise, heating methods are known which are based on the principle of induction. These are used, for example, in the hardening and heat treatment of components or component areas and for preheating in the welding processing of difficult-to-weld component materials, such as heat-resistant nickel-base superalloys, high-alloy steels, high-carbon iron base materials, precipitation-hardened aluminum alloys, copper materials or intermetallic materials (eg TiAl). used. Against this background, it is necessary to supply a plurality of movable components with electrical energy. Such components or components may be, for example, induction coils, heating plates, radiant heaters, electric motors powered grippers, spindles or other processing tools. These must be moved in different positions and can be supplied with electrical power during their movement and / or their use.

According to the prior art, so-called flexible leads or hose cables are often provided for this purpose, which enable a movement and / or the operation of a corresponding electrical load, such as a machining tool, gripper, heating element or an induction coil. A disadvantage of such flexible hose cables, however, that the ohmic resistance of the hose cable increases with increasing length, so that the maximum range of motion is limited by a maximum length of the hose for a given cable cross-section and a given power or with a given cable cross-section with increasing cable length, the available electrical Performance is limited. If, however, the line cross-section is increased for a higher transferable electrical power, the mobility of the hose cable is limited by lower mechanical elasticity. In addition, during movement of the hose cables, they are mechanically stressed by deformation, so that the life of the hose cable is limited. Furthermore, uncontrolled movements of the hose assemblies may result in problems due to entanglement of the hose assemblies with components of the apparatus or adjacent equipment or the like.

Another problem is that, when used in the field of manufacturing equipment, contaminants or abrasion may be deposited as a result of wear, which may disturb the mobility and / or electrical energy supply of the component.

Object of the present invention is to provide a device for movement and electrical power supply of a device, which allows reliable mobility and electrical contacting of a device over long periods of operation in polluting environments. Further objects of the invention are to provide a method for operating such a device as well as a production line for producing at least one component area of a component which comprises such a device.

The objects are achieved by a device having the features of claim 1, by a method according to claim 13 for operating such Device and solved by a manufacturing facility according to claim 14. Advantageous embodiments with expedient developments of the invention are specified in the respective subclaims, wherein advantageous embodiments of each invention aspect are to be regarded as advantageous embodiments of the respective other aspects of the invention.

The sliding contact can be formed by appropriate design basically directly by the holding element and the guide device. For example, the sliding contact may be formed by a guide rail of the guide device and a holder-side current collector. Alternatively, an additional sliding contact can be provided between the holding element and the guide device, via which the holding element and the guide device are at least electrically coupled. The electrical contact or the power supply of the component is thus realized even with a movement of the retaining element via abutting sliding contact surfaces of the sliding contact. This can in contrast to hose cables, strands or the like reduce the wear and increase the service life, which reduces maintenance costs or costs. On the other hand, comparatively large sliding contact surfaces can thus be realized, so that the electrical supply line can also be designed for larger outputs. The adjoining sliding contact surfaces can in principle be formed by any suitable material pairings. In general, for example, the use of an electrically conductive plastic or even paper is conceivable, preferably at least one of the sliding contact surfaces is formed by a metal. It may also be preferred that the sliding contact surfaces are formed by two materials of different hardness, for. As copper and graphite. A sliding contact surface can be formed by the relatively movable holding element itself or by a coating of the holding element in the region of the contact. It may, for example, a brush form the sliding contact surface, the contact so be a brush contact. Preferably, however, a continuous or flat material forms the sliding contact surface (s). In general, "a" within the scope of this disclosure are to be read as indefinite articles, that is to say always without expressly stated otherwise as "at least one" / "at least one".

A component 12 In the present case, a blade indicated by dashed lines for a turbomachine, for example for a compressor or a turbine of an aircraft engine, is built up from a powder bed in layers by local melting of a powdered component material with a laser (not shown, arranged in the observer plane). A powder bed intake 14 for the powder bed is in 1 drawn in dashed lines. The construction direction is perpendicular to the drawing plane, after the area-wise melting and thus solidifying a respective layer is the component 12 in the drawing plane and thus in the powder bed recording 14 lowered into it and covered with the next layer of powder.

The first guide rail 26a is in turn on a second holding element 20b arranged along the second movement path II and a second guide rail 26b is guided displaceably or translatorily. The first and the second movement path I, II are perpendicular to each other, so that the induction coil 18 flat across the powder bed holder 14 can be moved. In general, however, only one guide rail or only one holding element can be provided, or three or more guide rails and / or holding elements can be provided in order to be able to realize correspondingly complex movement paths. A special feature of the storage of the device 16 is that in addition to the mobility of the induction coil 18 also provides an electrical contact, since electrical energy from a power source of the device 16 over the sliding contact 24 between the second guide rail 26b and second holding element 20b and the sliding contact 24 between the first guide rail 26a and the first holding element 20a to the induction coil 18 and can be redirected back.

Due to the negative pressure impurities are thereby advantageously "sucked off" and removed and can optionally be separated from the fluid flow via downstream filters, cyclone cleaners and the like. Likewise, it may be provided that the cleaning device 30 - as in 3 shown - generates a relative overpressure, whereby a fluid flow of the cleaning medium 34 can be generated in the environment. The suction pipes 36 could in this case as well as pressure pipes 36 be designated. By pressurizing it is particularly easy, a cleaning medium 34 to use, which differs from the ambient atmosphere, so for example compressed air, a specific gas or gas mixture (inert gas / inert gas mixture), a liquid or a liquid mixture or a gas / gas mixture with a blasting agent or a liquid / a liquid mixture with a blasting agent , Furthermore, it is possible that the cleaning device 30 alternately generates a relative negative pressure and a relative positive pressure to produce a pulsating fluid flow.
