PLANT FOR MANUFACTURE OF COMPOSITE MATERIAL PRODUCTS BY SELF-SPREADING HIGH-TEMPERATURE SYNTHESIS Russian patent published in 1994 - IPC

FIELD: synthesis process. SUBSTANCE: pusher of press 18 lifts intermediate punch 10 above first layer 9 of female die, the layer is fastened on plate 19 of press. Third layer 8 of female die whose inner surface is coated with insulation 16 is mounted on intermediate punch 10. On lower punch gaskets 15 and porous filter 13 are installed. Preliminarily compacted stock briquet 21 is placed on porous filter. Then sections of second layer 7 are assembled and lower punch together with female die members goes down onto press table against the stop. Then porous filter 12, gaskets 14 and intermediate punch 11 are lowered to briquette. Top punch 17 is moved until its contact with intermediate punch 10. Then arson is set off, control system actuates press to start process. With generation of desired pressure press is cut off to provide isobaric time leg after which top punch is drawn upwards. Product is pressed out manually by lower pusher. Product from first layer 9 of female die is pressed out together with intermediate punch, filters, second and third layers of female die. Then sections of second layer and intermediate punches are put out. EFFECT: enhanced operating reliability. 4 cl, 1 tbl
