Abstract
1. Способ получения изделий из керамического порошка, включающий высокоскоростное прессование порошка путем ударного нагружения в стальной пресс-форме с металлическим пуансоном, расположенных соосно со стволом порохового метательного устройства на стальном основании, размещенном на песчаном грунте, отличающийся тем, что берут оболочку ударника из легкого высокопластичного металла в виде стакана, устанавливают в ней металлический отражатель, заполняют оболочку прессуемым керамическим порошком, при этом отношение удельной массы металлического отражателя к удельной массе слоя прессуемого порошка выбирают равным 0,61-0,97, запрессовывают крышку ударника и полученный при этом составной ударник размещают в канале ствола порохового метательного устройства, затем осуществляют ударно-волновое прессование керамического порошка путем разгона составного ударника пороховым зарядом до скорости 400-550 м/с и удара его в металлический пуансон, расположенный в осевом канале стальной пресс-формы, при этом процесс ведут при отношении суммы удельных масс дна оболочки составного ударника из высокопластичного металла, металлического отражателя, слоя прессуемого порошка и крышки ударника к сумме удельных масс металлического пуансона и стального основания, равном 0,25-0,41.2. Способ по п.1, отличающийся тем, что оболочку ударника выполняют из алюминия.3. Способ по п.1, отличающийся тем, что металлический отражатель изготавливают из стали.4. Способ по п.1, отличающийся тем, что металлический пуансон выполняют из стали.1. The method of obtaining products from ceramic powder, including high-speed pressing of the powder by impact loading in a steel mold with a metal punch, located coaxially with the barrel of the propellant throwing device on a steel base placed on sandy soil, characterized in that they take the shell of the drummer from the lung a highly plastic metal in the form of a glass, a metal reflector is installed in it, the shell is filled with extruded ceramic powder, while the ratio of the specific gravity is meta the reflector to the specific gravity of the pressed powder layer is chosen equal to 0.61-0.97, the drum cover is pressed in and the composite drummer obtained in this case is placed in the barrel channel of the powder propelling device, then the ceramic powder is shock-wave pressed by dispersing the composite drummer with the powder charge up to a speed of 400-550 m / s and hitting it in a metal punch located in the axial channel of the steel mold, the process being conducted with respect to the sum of the specific masses of the bottom of the shell of the composite impact and of superplastic metal, the metallic reflector layer and the pressed powder impactor cap to the sum of the specific gravities of the metal core and the steel base 0,25-0,41.2 equal. The method according to claim 1, characterized in that the shell of the striker is made of aluminum. The method according to claim 1, characterized in that the metal reflector is made of steel. The method according to claim 1, characterized in that the metal punch is made of steel.
