Abstract

The invention relates to powder metallurgy, in particular, to methods for producing articles from ferromagnetic powder. The goal is to simplify the way. Ferromagnetic powder fall asleep on a flat substrate of non-magnetic material placed on the magnet. The material forms a layer to form the desired bas-relief. After forming a bas-relief, it is poured with molten Wood alloy. After cooling and removing the magnets, a finished product of the desired shape is obtained. This method eliminates the use of the model.

Description

The invention relates to powder metallurgy, in particular, to methods for producing embossed articles by molding loose powder and subsequent impregnation.

The purpose of the invention is to simplify the process.

A method of making products from ferromagnetic powder is that

the bas-relief is gradually poured Wood alloy, for example, at a melt temperature of 90-95 ° C, until the whole surface is covered with an alloy. After the product has cooled, the magnet is removed from under the substrate and removed from it a bas-relief. Non-wood-impregnated powder particles are poured onto the substrate. The result is a hollow bas-relief. Example 2. Formed by the example

on a flat substrate of non-magnetic ma-

the material under which the magnet is placed, behind the Yu, the billet is sprinkled with Wood alloy powder

pour a portion of the ferromagnetic powder. and heat until the alloy is melted, do not remove the powder and impregnate the magnet from under the substrate. As pro-fusible alloy. The powder under the action of the workpiece is added. The powder of the flame field becomes similar to the plastic gg g. After cooling the product

,, .. 5 the magnet is removed and the bas-relief is removed from the substrate. Impregnation can also be carried out with nitro enamels, clear lacquers or glue.

The method allows to eliminate the need for forms, it is simple to implement.

Patch various shapes with complex surface relief. Impregnation of the relief in a magnetic field makes it possible to fix it and obtain a product.

Example 1. To make a bas-relief, iron powder or fine chips is pushed onto a flat brass substrate, under which a magnet is placed. Powder particles under the influence of a magnetic field are attracted to the substrate and to each other, forming

Invention Formula A method of manufacturing products from ferromagnetic powder, comprising a sufficiently thick layer to form a 25k portion of the powder, molding and impregnating a bas-relief of the required size. with the imposition of a magnetic field, the difference is that the Bas-relief is molded by hand, as in the case of modeling, in order to simplify, filling the bas-relief of clay. Convex and concave portions of the powder are carried out on a flat y-acTKii relief, and the substrate is well supported and placed on a magnet and in a horizontal layer. Then onto the surface made of non-magnetic material. the bas-relief is gradually poured Wood alloy, for example, at a melt temperature of 90-95 ° C, until the whole surface is covered with an alloy. After the product has cooled, the magnet is removed from under the substrate and removed from it a bas-relief. Non-wood-impregnated powder particles are poured onto the substrate. The result is a hollow bas-relief. Example 2. Formed by example the billet is sprinkled with Wood alloy powder Invention Formula A method of manufacturing products from ferromagnetic powder, including filling a portion of the powder, molding and impregnating with the imposition of a magnetic field, differing in that, for the purpose of simplification, the filling of a portion of the powder is carried out on a flat substrate placed on the magnet. and made of non-magnetic material.
