Description

Изобретение относитс  к порошковой металлургии, в частности к полу- . чению изделий из металлической струж-, ки.The invention relates to powder metallurgy, in particular to semi-. products from metal shavings.

Целью изобретени   вл етс  снижение себестоимости изделий из стружковых отходов.The aim of the invention is to reduce the cost of products from chip waste.

Способ включает очистку стружки от смазочно-охлаждаемой жидкости, предварительное брикетирование стружки , отделение поверхности брикета из стружковых отходов от поверхности рабочего инструмента слоем порошкового материала, прессование и спекание .The method includes cleaning chips from coolant, pre-briquetting chips, separating the surface of the briquette from the chip waste from the surface of the working tool with a layer of powder material, pressing and sintering.

При получении изделий по предлагаемому способу дол  пор ошкового материала в массе издели  составл ет 15-20%, в св зи с чем издели  из Upon receipt of the products according to the proposed method, the proportion of oshkovogo material in the mass of the product is 15-20%, in connection with which the products from

стружковых отходов имеют себестоимость , равную 40-50% от себестоимости изделий из порошков.chip waste has a cost equal to 40-50% of the cost of products from powders.

Пример. Стружковые отходы, например стали 08 с размерами частиц 3x1x0,5 мм, очищают от смазочно- охлаждаемой жидкости п тиразовой промывкой в гор чей воде, затем подвергают сушке. Очищенную стружку брикетируют в пресс-форме с размерами 50x10 MN, под давлением 600 МПа. Относительна  плотность брикетов составл ет 76%.Example. Chip wastes, such as steel 08 with a particle size of 3x1x0.5 mm, are cleaned from coolant with a five-fold washing in hot water, then dried. The cleaned chips are preformed in a mold with dimensions 50x10 MN, under a pressure of 600 MPa. The relative density of the briquettes is 76%.

Брикет устанавливают в пресс-форму с размерами 52-12 мм, предварительно на нижний пуансон насыпают слой порошкового материала ПЖЗМ высотой 1-1,5 мм. Зазор между боковой поверхностью брикета и стенками матрицыThe briquette is installed in the mold with the dimensions of 52-12 mm; previously, a layer of the powder material ПЗЗМ height 1-1.5 mm is poured on the lower punch. The gap between the side surface of the briquette and the walls of the matrix

The powder is applied in such a way that the powder covers the upper end surface of the briquette by about i - 1.5 mm. Pressing is carried out under a pressure of 800 MPa. Finished pressing is baked at. The product density is 89%. The roughness from the end surface is 0.085 µm, and the lateral surface is 0.125 µm, which corresponds to 10 quapity according to GOST 2789-73,
