Abstract
Способ гидростатического прессования изделий из порошка, включающий засыпку порошка в полость пресс-формы между закладным формообразующим элементом и внешней эластичной оболочкой, предварительное гидростатическое прессование при давлении меньшем рабочего давления, удаление закладных элемента, последующее гидростатическое прессование рабочим давлением гидростата и последующее температурное спекание, отличающийся тем, что в пресс-форму устанавливали дополнительный конструкционный элемент (обечайку), полость между ней заполняли смесью из порошка основного материала изделия (меди) и порошка другого металла, которую получали в отдельном устройстве, обечайку удаляли перед предварительным гидростатическим прессованием.A method for hydrostatic pressing of products from a powder, which includes filling the powder into the mold cavity between the embedded forming element and the outer elastic shell, preliminary hydrostatic pressing at a pressure lower than the operating pressure, removing embedded elements, subsequent hydrostatic pressing with the working pressure of the hydrostat and subsequent temperature sintering, characterized in that that an additional structural element (shell) was installed in the mold, the cavity between it was filled with a mixture of the powder of the main material of the product (copper) and powder of another metal, which was obtained in a separate device, the shell was removed before preliminary hydrostatic pressing.
