Grinding the grinding by mill 27 in track 28, the metal dust after grinding is transported to feed mechanism 3 by material leakage pipe 31
Metal dust feeding storehouse 32 in, cylinder A311 and cylinder B312 carries gas in material leakage pipe 31, starts reducing motor A35,
Metal dust after quickly grinding in material leakage pipe 31 under gas pressure effect is transported in metal dust feeding storehouse 32, passes through
Under the conveying of helical blade 33, feeding metal dust is transported in the middle part of the backing plate 42 of weighing of Weighing mechanism 4 by passage 36
In tremie pipe 67, determine that the weight of feeding metal dust reaches the weight of the standard setting of metal forming by weight sensor 44
Time, reducing motor B61 opens, and carrier wheel 58 moves along clamping rings 63 medial surface, drives simultaneously and drives pull bar 54 end
Limited block 52 moves along housing 51 to base 62 direction, when feed opening 511 is relative with spacing hole 521, and the feeding in tremie pipe 67
Metal dust leaks down, and the feeding metal dust in tremie pipe 67 all falls through into the hollow cylindrical injection in fixed bin 84
In device 82, by under the elastic-restoring force effect of back-moving spring 83, the metal dust in hollow cylindrical syringe 82 is passed through
Arrange metal dust material leakage passage 80 at fixing mould 69 upper section central to be expelled in hollow circular cylinder 77, open hydraulic cylinder 6-1
Switch, now hydraulic cylinder 6-1 drives piston rod 70 to move up, and low bottom-disc 72 and lower diel 73 depart from bracing frame 68,
Piston rod 70 drives crushing block 741 to move upward simultaneously, and crushing block 741 drives lower diel together with resilient support members 74
73 move upward, until extruding groove 81 matches with hollow circular cylinder 77, it is achieved crushing failure at high speed forming process, piston rod 70 is downward
Mobile, low bottom-disc 72 returns to home position together with lower diel 73, and now piston rod 70 moves again up and drives extruding
Block 741 moves upward, by the metal module of molding in hollow circular cylinder 77 along mobile bar A742, mobile bar B743 and push rod 7411
Eject so that it is depart from hollow circular cylinder 77, under the resilient force of stage clip 76, make resilient support members 74 return, i.e. extrude
Fast 741 contact with rectangular channel 75 bottom surface of lower diel 73, and feeding metal dust is spacing the most next time, accurately,
The feed precision of quick control metal, and the forming process of metal dust.
The present invention can pass through or use prior art to realize without the technical characteristic described, and does not repeats them here, certainly,
Described above is not limitation of the present invention, and the present invention is also not limited to the example above, the ordinary skill of the art
Change that personnel are made in the essential scope of the present invention, retrofit, add or replace, also should belong to the present invention.
