Definitions
- the invention relates to a method for producing metallic lattice structures in the form of open-pored foam.
- Reticular structures of metal and other materials are due their properties a wide range of applications. For example, you can these structures as low weight components, accumulator plates, electrochemical anodes and cathodes, filters and mixers for fluids, catalyst, Gas absorbers, heat exchangers and many other applications be used.
- U.S. Patent 3,616,841 discloses a method of manufacture a foam material having a predetermined reticulated structure. This method involves the preparation of a self-supporting reticulated Polyurethane foam; the production of a refractory mass by the cavities of the polyurethane foam with an aqueous molding material suspension are filled and this suspension sets; heating the refractory Mass at a temperature of about 120 ° C (250 ° F) over a period of two hours to dry; the creation of cavities in the refractory Molding composition by raising the temperature of the refractory molding composition to 650 to 850 ° C is increased to volatilize the entire foam; the introduction a molten substance consisting of metals or metal alloys, into the refractory molding compound, the amount of substance being sufficient to fill the cavities previously occupied by the reticulated structure were; and solidifying the molten substance in which the Temperature is reduced so that it is below the melting point of the substance lies; and washing out the material forming
- DE 199 39 155 discloses a method for producing metallic lattice structures, in which a reticulated foam pre-structure in a hinged container is used, the foam preform with a refractory Material infiltrated and the refractory material is then solidified. Subsequently the solidified refractory material is removed from the hinged container, the foam pre-structure removed from the refractory material and the resulting, preheated body is inserted into a heat-resistant container. This body is infiltrated with a molten metal and after the Solidification of the molten metal removed from the heat-resistant container. Subsequently, the refractory material is removed from the body, thereby As a result, a reticular metal structure is obtained.
- the object of the invention is therefore to overcome the disadvantages of the prior art remove. It is intended in particular a method for producing metallic Grid structures are given, which require less material and a faster production of such structures and consequent mass production allows.
- the pre-structure by flat or separately thermally compressing the pre-structure so as to be external inward growing pores and thus a graded structure in the Having area of compression, and for the production of metallic lattice structures
- a reticulated Prestructure preferably a PU foam structure to use, but whose Previously by single or multiple coating, by means of one or more various organic materials, to thicken.
- Procedural steps the inflow of the metal is facilitated.
- the mechanical properties of the structure can be targeted be influenced, wherein it is essential that the reproducibility of the characteristics is sustainably improved over the prior art.
- the thickness of the Webs of PU foam structure the respective, from the purpose of the Metal grid structure determine requirements adapted.
- the coating of the webs of the pre-structure by means of liquid and / or solid Materials provided, for. B. by dipping the Vor Quilt in liquid Wax and then coating with wax powder (this is another Melting temperature) or a polymer powder, such as polystyrene or polyamide powder, which also imply a small amount of adhesive, preferably 5% by volume can.
- the use of powder prevents sticking of the Structure and ensures a uniformly thick layer, especially since there are no membranes Form (cell skins) between the webs.
- VorDeutsch After such a Vortechnik has been generated, it is for the casting in fixed to a molding material.
- the Vor Carl is inserted in register in a frame and with Molded material poured so that it is not completely covered, but rather a boundary of 2 to 5 mm remains free.
- the remaining cavities are filled with sand and pressed.
- the sheathing of the pre-structure is done with a ceramic slurry, the coating being optionally repeated, to create a stable layer.
- the embedded molding can be used previously Need be reworked, such. B. by milling and drilling to nubs or to create other geometric shapes of solid material in the structure, or through holes to pipes by means of core pins in the structure pour.
- the incorporation of consistent, but also non-consistent Holes, grooves or the like in the cast Vortechnik takes place according to the invention at a distance of at least two pores from each other. This process step has the consequence that the density of the material and consequently its stability can be increased application specific; At the same time there is a sustained improvement in thermal conductivity.
- the Diameter of the recesses will be according to the strength requirements optimized
- Vor Vor Modell by melting and / or burnout
- this is the solidified Structure-ceramic composite removed from the frame and in a cuvette whose bottom is made of loose refractory material, preferably Foundry sand, filled, introduced.
- the cuvette comprises a molding sand / ceramic stencil for the runners; In addition, it has insulation to prevent premature cooling of the molded part to prevent.
- the cuvette consists of a pressed molding sand / ceramic composite, where the molding sand is recyclable and also the use of molding material is reduced to the necessary volume.
- the cuvette with the molded part is placed in a pressure-resistant container, filled with liquid metal, the container closed and evacuated to the Molding and the melt to degas.
- the melt By aerating the container is the Melt pressed into the molding.
- the crucible is in the container, the cuvette is connected to the melt through a tube.
- the Molded part removed from the cuvette.
- the solidification can be directed over the cast metal parts done.
- the preliminary structure can also by pouring granular mineral Substances or granular organic substances with a mineral coating be generated.
- granular structures preferably in spherical Pellets
- the pore sizes of the lattice structure substantially to expand.
- PU foam structures usually pore sizes by Max. 5 ppi, which corresponds to an average pore diameter of 8 to 10 mm, can be hereby pore sizes in the range from 1 to 3 cm.
- the pellets are large to each other glue, so that is sure that only the voids between the Pellets are used.
- a coating of the preliminary structure thus created is not intended and not necessary because the desired ceramic Coating already exists. The other method steps according to the invention are retained.
- the structure thus created presents itself as more diverse Lightweight material.
