Description
Technical field
The utility model relates to powder compacting field, is specifically related to the powder former with pressure holding function.
Background technology
The helicoid powder former of the many employings of existing powder metallurgy is pressed to metal dust, its principle arranges multiple station in pivotal mid-game, station comprises master mold, upper and lower correspondence arranges and can insert mo(u)ld top half and the mo(u)ld bottom half of master mold, mo(u)ld top half and mo(u)ld bottom half are connected to pressure bar and lower pressure bar, when station goes to upper pressure wheel and lower pressure wheel, upper pressure bar and lower pressure bar are under the common pressure effect of upper pressure wheel and lower pressure wheel, by mo(u)ld top half and mo(u)ld bottom half press-in master mold, the powder in master mold is made to make briquet at huge pressure, this helicoid powder former has the high advantage of compacting efficiency, but because station is through upper pressure wheel and lower pressure wheel, with upper pressure wheel and lower pressure wheel very short for time of contact, make master mold can only suppress the briquet of simple shape, for the briquet of complicated shape, because pressing time is shorter, powder sizing cannot be made, its reason is, because powder causes temperature to raise in pressure process, shaping briquet is expanded, and when mo(u)ld top half and mo(u)ld bottom half detach master mold, the easy swelling fracture of briquet, on the other hand, due to mo(u)ld top half or mo(u)ld bottom half directly leave master mold time, vacuum is produced in master mold cavity, briquet is made to occur bursting apart, and for not adding the powder of condensation glue (as PVA glue), also cannot be compressing.To this, the method solved in existing industry mainly contains two kinds, one is the speed of gyration reducing station, the time of contact of station and upper pressure wheel and lower pressure wheel is increased with this, but this method sacrifices speed of production, production efficiency is reduced, there is difference in height in its lower pressure wheel and lower guideway, lower pressure bar mo(u)ld bottom half when pressurizeing gyration is moved up and down in master mold, cause upper pressure bar and briquet do not leave master mold at present pressure bar namely drop, still there is the situation of the vacuum produced when mo(u)ld top half and mo(u)ld bottom half leave master mold, still cannot process the briquet of too complicated shape; Another kind method is carried out the compacting of briquet, and it is longer that oil pressure unit has benefited from stroke, and pressing speed is slow, therefore the briquet suppressed is effective, can suppress the briquet of comparatively complicated shape, but its efficiency is low compared with the powder former of Clothoid type, can not meet Production requirement far away.
