Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines in einer Werkzeugmaschine bewegbaren Metallbauteils, vorzugs weise eines Schlittens der Werkzeugmaschine, wobei das Me tallbauteil durch eine geschlossene Außenschale aus Metall gebildet ist, deren Innenraum zumindest teilweise mit einem Metallschaum gefüllt ist.The invention relates to a method for producing a a machine tool movable metal component, preferred as a carriage of the machine tool, the Me tall component by a closed outer shell made of metal is formed, the interior of which is at least partially covered by a Metal foam is filled.
Ein derartiges Herstellungsverfahren ist beispielsweise durch die DE 198 33 125 A1 bekannt geworden.Such a manufacturing process is, for example made known by DE 198 33 125 A1.
Hochdynamische Werkzeugmaschinen (Bearbeitungszentren) er fordern Leichtbau-Strukturen in Form von z. B. Leichtmetall guß oder dünnwandigen Stahl-Schweiß-Konstruktionen. Leicht metallguß-Bauteile besitzen zwar eine erhöhte mechanische Dämpfung, weisen aber immer noch ein recht hohes Gewicht auf. Demgegenüber läßt sich mit dünnwandigen Stahl-Schweiß- Konstruktionen zwar ein geringes Gewicht erreichen, aller dings besitzen diese Konstruktionen nur sehr schlechte Dämp fungseigenschaften über den gesamten während des Betriebs der Werkzeugmaschine auftretenden Frequenzbereich.Highly dynamic machine tools (machining centers) demand lightweight structures in the form of e.g. B. light metal cast or thin-walled steel-welded constructions. Easy cast metal components have an increased mechanical Damping, but still have a fairly high weight on. In contrast, thin-walled steel welding Constructions may be light in weight, all However, these constructions only have very poor dampers performance characteristics throughout the entire operation frequency range of the machine tool.
Aus der eingangs genannten DE 198 33 125 ist es bekannt, die Biege- und Verwindungsteifigkeit von Trägerprofilen einer Werkzeugmaschine durch vollständiges oder teilweises Aus schäumen mit schäumbarem Aluminiumwerkstoff oder eines ande ren geeigneten schäumbaren Metalls zu erhöhen. Das Ausschäu men der Trägerprofile erfordert allerdings einen relativ großen Glühofen oder den Einsatz von Induktionsspulen, so daß das Ausschäumen in der Regel nicht vom Werkzeugmaschi nenhersteller selbst, sondern an anderem Ort durchgeführt wird. Daher ist das Ausschäumen der Trägerprofile mit hohem Transportaufwand verbunden.From the aforementioned DE 198 33 125 it is known that Bending and torsional stiffness of beam profiles one Machine tool through complete or partial shutdown foam with foamable aluminum material or another to increase their suitable foamable metal. The Ausäu men of the support profiles, however, requires a relative large annealing furnace or the use of induction coils, so that the foaming is not usually from the machine tool manufacturer itself, but carried out at a different location becomes. Therefore, the foaming of the carrier profiles is high Transport costs connected.
Es ist daher die Aufgabe der Erfindung, bei einem Herstel lungsverfahren der eingangs genannten Art den beim Herstel len des mit Metallschaum gefüllten Metallbauteils anfallen den Kosten- und Zeitaufwand zu verringern.It is therefore the object of the invention in a manufacturer lation process of the type mentioned at the start of the manufac len of the metal component filled with metal foam reduce costs and time.
Diese Aufgabe wird in einem ersten Aspekt der Erfindung da durch gelöst, daß die Pulvermischung des Metallschaums in einer dem Innenraum der Außenschale etwa entsprechenden Ko kille aufgeschäumt und dann in die Außenschale eingeklebt wird.This object is achieved in a first aspect of the invention solved by that the powder mixture of the metal foam in a Ko approximately corresponding to the interior of the outer shell foamed kille and then glued into the outer shell becomes.
Der mit der Erfindung erzielte Vorteil besteht darin, daß der Metallschaum außerhalb des Metallbauteils aufgeschäumt werden kann und der aufgeschäumte Metallschaum auch ohne das Metallbauteil transportiert werden kann.The advantage achieved by the invention is that the metal foam is foamed outside the metal component can be and the foamed metal foam without that Metal component can be transported.
Die Pulvermischung (Rohmasse) des Metallschaums wird in die Kokille eingelegt und darin durch Wärmezufuhr aufgeschäumt. Die Rohmasse ist im allgemeinen eine Mischung aus Metallpul ver und einem Treibmittel, die - gegebenenfalls nach geeig neter Vorbehandlung - durch Erwärmung auf Temperaturen ober halb der Solidus-Temperatur der jeweiligen Legierung zu ei nem Werkstoff expandiert und dabei seine hochporöse, ge schlossen-zellige Porenstruktur entfaltet.The powder mixture (raw mass) of the metal foam is in the Chilled mold inserted and foamed by heat. The raw mass is generally a mixture of metal powder ver and a blowing agent, which - if appropriate after appro pretreatment - by heating to temperatures above half the solidus temperature of the respective alloy nem material expands while its highly porous, ge closed-cell pore structure unfolds.
Die geschlossene Außenschale kann ein- oder mehrteilig aus gebildet sein. Vorzugsweise sind die Innenseite der Außen schale und der Metallschaum zumindest in Teilbereichen mit einander formschlüssig verbunden. Dazu kann z. B. die Innen seite mit einer Struktur (Raffelung, Zahnung, Nuten etc.) versehen sein, in die der Metallschaum eingreifen kann.The closed outer shell can consist of one or more parts be educated. Preferably the inside is the outside shell and the metal foam at least in some areas connected to each other in a form-fitting manner. For this, e.g. B. the inside side with a structure (shirring, toothing, grooves etc.) be provided in which the metal foam can engage.
Die Außenschale kann durch ein Metallblech, z. B. durch ein Stahlblech oder eine Stahl-Schweißkonstruktion, gebildet sein. Um einen Formschluß zwischen dem Stahlblech und dem Metallschaum zu erreichen, können die nach innen gebogenen Blechenden entsprechend geformt, z. B. gezahnt sein. Ausge schäumte Stahlbauteile sind prinzipiell recyclingfähig.The outer shell can by a metal sheet, for. B. by a Sheet steel or a welded steel structure his. To a positive connection between the steel sheet and the To achieve metal foam, those bent inwards can Sheet ends are shaped accordingly, e.g. B. be serrated. Except Foamed steel components are in principle recyclable.
Vorzugsweise ist der Metallschaum ein Schaum aus Aluminium, Zink, Blei oder Bronze, wobei für Werkzeugmaschinen Alumuni um-Schaum bevorzugt wird.The metal foam is preferably an aluminum foam, Zinc, lead or bronze, with Alumuni for machine tools um foam is preferred.
In einem zweiten Aspekt der Erfindung können auch bereits aufgeschäumte Metallschaumkugeln in die Außenschale einge füllt und darin verklebt werden. Insbesondere bei Metallbau teilen mit großen Querschnitten ist es von Vorteil, wenn der unbelastete Metallschaumkern zur Gewichtseinsparung ausge spart ist. Dazu kann im Innenraum der Außenschale mindestens ein Hohlraum vorgesehen sein, der frei von Metallschaum ge lassen ist. Ein solcher Hohlraum kann z. B. dadurch erzeugt werden, daß vor dem Befüllen des Innenraums ein Hohlkörper (z. B. ein Stahlrohr etc.) eingelegt wird.In a second aspect of the invention can already foamed metal foam balls inserted into the outer shell fills and glued into it. Especially in metal construction parts with large cross sections, it is advantageous if the unloaded metal foam core to save weight saves. For this, at least in the interior of the outer shell a cavity may be provided which is free of metal foam is let. Such a cavity can e.g. B. generated thereby be that a hollow body before filling the interior (e.g. a steel pipe etc.) is inserted.
