Abstract
Изобретение относитс к способам непрерывного прессовани изделий из порошков и устройствам дл их осуществлени . Целью изобретени вл етс снижение энергозатрат. Порошок 6 непрерывно подаетс в винтовую нарезку экструдирующего шнека 2. Перемеща сь в нарезке при помощи вращени обоймы 1, порошок прокатываетс валками 5, причем прокатка ведетс ступенчато с возрастанием усили в заключительных витках шнека. После прокатки уплотненный и прокатанный порошок формообразуетс в насадке в изделие заданной формы. 2 с.п.ф-лы, 3 ил., 1 табл.The invention relates to methods for the continuous pressing of articles from powders and devices for their implementation. The aim of the invention is to reduce energy costs. Powder 6 is continuously fed into the screw cutting of the extruded screw 2. By moving the cutting by rotation of the sleeve 1, the powder is rolled by the rolls 5, the rolling being stepped with increasing force in the final turns of the screw. After rolling, the compacted and rolled powder is formed in a nozzle into a product of a given shape. 2 sp.f-ly, 3 ill., 1 tab.
