Definitions

the invention relates to a method for producing metal moldings, in particular weight-reduced moldings made of light metal.
GB 892934 relates to the production of complex structures with foamed metal core and closed non-porous surface.
DE 198 32 794 C1 describes a method for producing a hollow profile filled with metal foam. This method comprises the steps of pressing the hollow profile from a cladding material with an extruder having an extrusion die with a die and a mandrel, feeding the metal foam from a foam material through a supply channel to the hollow profile formed in the mandrel.
a wheel for a motor vehicle which comprises at least one metallic foam core, which is arranged exposed to the inside of the wheel and has a casting wall towards the outside of the wheel.
the foamed aluminum foam core is placed in a mold to cast the wheel and positioned so that the outer casting skin is formed between the mold and the foam core during casting.
DE 195 02 307 A1 describes a deformation element, in whose housing a filling of an aluminum foam is provided as an energy absorber.
the housing may be made of metal or plastic.
the filler is a mere insert without material connection to the housing.
So z. B. in the DE 195 01 508 C1 claimed a component for the chassis of a motor vehicle and a method for producing such a component.
a core of aluminum foam is introduced into a die, which remains after the pressing of the aluminum in the mold in the component of die-cast aluminum (principle of the lost core).
the aluminum foam used is produced from a mixture of aluminum powder with a blowing agent and is produced in a manner known per se in a multistage process (such a process is described, for example, in the article "Economic Production Techniques for the Production of Aluminum Foams, Aluminum, Volume 76 2000, page 491 ff) DE 195 01 508 C1
the invention is therefore a process for the production of metal moldings according to the preamble of claim 1, which is characterized in that one inserts metal body according to the characterizing part of claim 1 with all sides closed surface and a hollow structure in the interior in a mold and the remaining mold cavity with a metal or a metal alloy is filled.
the surface area of the metal body preferably has a higher average density than the interior of the metal body by a factor of 1.5 to 20, preferably 3 to 15, particularly preferably 5 to 10.
the molded article produced therefrom is correspondingly reduced in weight.
the metallic structure surrounding the metal body core
the molded article produced therefrom is correspondingly reduced in weight.
no weight reduction is associated with it, but an optionally more expensive material can be produced more cheaply by embedding a cheaper shaped article.
a metal foam core is suitable, which has an integral foam structure.
the metal body is encapsulated with a liquid molten metal, which can be done for example in a die casting machine.
Light metals in particular aluminum or aluminum alloys, are particularly suitable for the process according to the invention, it being possible for the metals or alloys used to produce the moldings to be different from those of the molded articles.
the metal body used is a metal integral molded foam which, in contrast to the foam bodies conventionally described in the literature, does not have a uniform foam morphology along its cross section.
a metal body is a molded foam body that can be produced in the outer zones contour-faithful and whose outer shell is close to the density of the metal or the metal alloy used.
This metallic integral foam thus represents a true gradient material. Inside the molded body, however, the density is reduced by the occurrence of gas bubbles, so that the average density of the entire molded body is below the theoretical density of the metal or metal alloy used (FIG.).
the average density per cubic millimeter of the outer millimeter layer of the molding is by a factor of 1.5 to 20, preferably 3 to 15, particularly preferably 5 to 10, higher than the average density in the interior of the molding.
Such moldings are produced by a die-casting directly from the melt with the addition of a blowing agent.
the thickness of the outer skin of the molded body and thus the temperature and pressure stability can be adjusted according to the particular use, while the contour accuracy of the resulting molded body allows exact positioning during further processing.
the metal body to be used according to the invention be used to reduce a complicated metal casting in the weight that they are used as remaining in the final product cores.
the virtually closed outer skin of the integral molded foam body to be used in accordance with the invention also makes it suitable for use in vacuum casting processes, since the quality of the resulting surface makes it possible to evacuate the casting mold in the final body production method according to the invention, without any continuously disturbing gas leakage from the interior of the core body and thus accompanying decrease in the vacuum observed.
the introduction of the Integralformschaumkernes in the mold used can either manually or by conventional industrial methods, eg. B. by robots done.
the subsequent encapsulation and thus the formation of the weight-reduced target workpiece can be done due to the temperature and pressure stability of the core body outer skin quite well with metals or metal alloys of a higher melting point or at a higher processing temperature than the melting point of the core material.
Such a procedure the use higher even provides the advantage that the outer surface of the core body is partially melted and thus forms during the subsequent solidification process of the end body an intimate metallic bond between the core material and the enveloping shell material of the Endwerk unanimouses.
a vehicle part should be made of an aluminum material as an integrally foamed metal body.
a casting chamber of a die casting machine was filled with a corresponding amount of molten metal.
magnesium hydride in powder form was added to the liquid metal as foam-producing blowing agent.
the mold cavity was underfilled volume defined. Due to the resulting turbulence is a good mixing in the mold cavity and the foaming of the cavity.
the metal solidified on the mold walls and formed a dense and homogeneous wall of the metal body, wherein both the wall thicknesses and the porosity and its gradient could be adjusted by varying process parameters.
the component had a mass of only about 40% compared to conventional die castings made of the same material.
the metal body produced according to the example was then used as the core in a larger mold inserted and closed the mold. Then, according to the usual die casting method, a molten metal was pressed from the casting chamber of the die casting machine into the mold cavity. In this filling the mold cavity was completely filled, excess metal was removed after cooling of the molding from the Anschusskanal and the end of the casting chamber. The result of this process was a weight-reduced molded part, which had cavities in the region of the inserted core body, but in the area of the non-core-filled structures corresponded to a solid casting.
the molded article produced according to the example had a lower density and a better vibration absorption behavior than the corresponding solid material comparison body.
