The operation principle that the present invention throws the powder machine is:
Dissimilar metallurgical powders is put into first charging basket and second charging basket respectively, start switch, make first hydraulic cylinder promote planker along the guide rail movement on the supporting plate, the die cavity piece is moved to first charging basket below, at this moment, first charging basket begins to throw powder, throws the powder process to be:
First pneumatic cylinder drives first pushing block first pumping board is extracted out; Make metallurgical powder fall on second pumping board of second hopper from first hopper; Weighing batcher calculated weight by the second pumping board rear end; After reaching preset value, it is closed with first pumping board that first pneumatic cylinder drives first pushing block, stops first hopper and add powder to second hopper.
When first pumping board was closed, second pneumatic cylinder drove second pushing block second pumping board is extracted, and metallurgical powder drops into the square type dead slot in the middle of the die cavity piece through the 3rd hopper, throw in finish after second pneumatic cylinder drive second pushing block second pumping board closed.
Throw in the powder process at first charging basket, first hydraulic cylinder promotes planker and slowly moves, and just in time the bottom of the square type dead slot in the middle of the die cavity piece is paved with one deck powder equably when first charging basket throwing powder finishes.After the input of first charging basket finishes; First hydraulic cylinder continues to promote planker and drives the below that the die cavity piece moves to second charging basket, and second charging basket begins to throw powder, repeats above-mentioned throwing powder process; But the corresponding construction of second charging basket is in motion; At this moment, first hydraulic cylinder promotes planker and slowly moves along guide rail, when second charging basket throwing powder finishes, just in time in the square type dead slot in the middle of the die cavity piece, is paved with second layer powder equably.
Afterwards, first hydraulic cylinder pulling planker drives the die cavity piece and returns first charging basket below, throws powder again, is pushed into second charging basket below again, throws powder again, repeats to throw the powder process, in the square type dead slot of die cavity piece, is paved with the powder that presets the number of plies.
After throwing powder work completion, first hydraulic cylinder promotes planker drive die cavity piece and moves under the compacting punch, and second hydraulic cylinder promotes the compacting punch from top to down and is pressed in the middle square type dead slot of die cavity piece, with the metallurgical powder compacting; Then, second hydraulic cylinder drives the compacting punch and raises, and separates soon with die cavity, accomplishes the powder pressing in the die cavity piece.
Dynamical system of the present invention is:
After mechanically activated, limit switch moves under first charging basket, second charging basket through first hydraulic cylinder, guide rail and planker control die cavity piece; When limit switch was responded to, first pumping board was extracted out, and powder directly contacts with second pumping board; When the pressure on second pumping board reaches certain value; Signal feedback on second pumping board is to first pumping board, and first pumping board is just closed, after the complete closure of first pumping board; Second pumping board is extracted out, and powder directly falls in the die cavity piece; Under first charging basket, second charging basket, repeat to move, throw powder; After throwing the powder completion; Below 5 seconds, (this time length can artificially be set) die cavity piece was moved to the compacting punch by first hydraulic cylinder (by limit switch induction and control); The compacting punch is pressed downward under the effect of second hydraulic cylinder; After 3 seconds (this time length can artificially be set) compacting punch raise, separate with the die cavity piece.At last, movable push rod ejects being compacted into block powder metallurgy blank body under the effect of the 3rd hydraulic cylinder, carries out sintering in the metallurgy sintered stove so that send into subsequently.
Good effect of the present invention is:
Adopt the mechanical hand jettison system, in process of production, control powder process and the throwing powder amount of throwing automatically by equipment; Cause production process to become simple relatively, and simple to operate, easy to use; Be convenient to improve product precision and efficiency, reduce production costs, strengthened the competitiveness of enterprise.
