Abstract
Способ изготовления полости и отверстия в прессованной заготовке, осуществляемый с использованием вставки и пресс-формы, отличающийся тем, что на вставку наносят слой реологической жидкости, а на последнюю насыпают осесимметричные гранулы из легкоплавкого материла, затем вставку с жидкостью и гранулами помещают в магнитное поле и выдерживают до затвердевания реологической жидкости, затем вставку с реологической жидкостью и гранулами устанавливают в пресс-форму и прессуют до формования заготовки, после чего снимают магнитное поле, удаляют реологическую жидкость и спекают заготовку при температуре выше температуры плавления материала гранул, удаляют расплавленные гранулы и вынимают из заготовки вставку.A method for manufacturing a cavity and a hole in a pressed billet, carried out using an insert and a mold, characterized in that a layer of rheological liquid is applied to the insert, and axisymmetric granules of low-melting material are poured onto the latter, then the insert with the liquid and granules is placed in a magnetic field and hold until the rheological liquid solidifies, then the insert with the rheological liquid and granules is installed in the mold and pressed until the workpiece is formed, after which the magnetic field is removed, the rheological liquid is removed and the workpiece is sintered at a temperature above the melting point of the material of the granules, the melted granules are removed and removed from workpiece insert.
