Claims (10)

1. Способ изготовления сопрягаемых друг с другом частей детали, в котором одновременно прессуют и формуют порошок на основе железа, используя форму, снабженную одной матрицей, имеющей полости для формования неспеченного корпуса, изготовленного за одно целое; подвергают механической обработке неспеченный корпус; раскалывают с изломом неспеченный корпус, по меньшей мере, на две части по предназначенным для раздела поверхностям; спекают части и вновь сопрягают части по поверхностям раздела.1. A method of manufacturing mating parts of a part in which iron-based powder is pressed and molded simultaneously using a mold provided with a single matrix having cavities for molding an unsintered body made in one piece; machining an unsintered body; cracking an unsintered casing with a fracture into at least two parts along surfaces intended for partitioning; parts are sintered and parts are again mated over interface surfaces. 2. Способ по п.1, в котором неспеченный корпус имеет прочность неспеченного материала, по меньшей мере, 20 МПа, предпочтительно, по меньшей мере, 25 МПа и наиболее предпочтительно, по меньшей мере, 30 МПа. 2. The method according to claim 1, in which the green body has a green strength of at least 20 MPa, preferably at least 25 MPa, and most preferably at least 30 MPa. 3. Способ по п.1 или 2, в котором прессование выполняют путем использования технологии горячего прессования. 3. The method according to claim 1 or 2, in which the pressing is performed by using the technology of hot pressing. 4. Способ по п. 1 или 2, в котором прессование выполняют в матрице со смазкой. 4. The method according to p. 1 or 2, in which the pressing is performed in a matrix with lubricant. 5. Способ по п.1 или 2, в котором в металлический порошок включают вещество, повышающее прочность неспеченного материала. 5. The method according to claim 1 or 2, in which the metal powder includes a substance that increases the strength of the green material. 6. Способ по любому из предшествующих пунктов, в котором стадию механической обработки выполняют после стадии спекания. 6. The method according to any one of the preceding paragraphs, in which the machining step is performed after the sintering step. 7. Способ по любому из предшествующих пунктов, в котором спеченные части подвергают термической обработке. 7. The method according to any one of the preceding paragraphs, in which the sintered parts are subjected to heat treatment. 8. Спеченные части, сопрягаемые в пары, изготовленные из механически обработанного и расколотого с изломом неспеченного корпуса, причем указанный неспеченный корпус изготовлен из прессованного порошка на основе железа и имеет прочность неспеченного материала, по меньшей мере, 20 МПа. 8. Sintered parts mating in pairs made of machined and fractured with a fracture unsintered body, wherein said unsintered body is made of pressed powder based on iron and has a strength of unsintered material of at least 20 MPa. 9. Части по п.8, в которых неспеченный корпус имеет прочность неспеченного материала, по меньшей мере, 25 МПа. 9. The parts of claim 8, in which the green body has a green strength of at least 25 MPa. 10. Части по пп.8 и 9, применяемые для изготовления шатунов. 10. Parts of paragraphs 8 and 9, used for the manufacture of connecting rods.
