The purpose of this utility model can reach by following measure: the vacuum induction quick quenching furnace, include the vacuum induction melting chamber, vacuum quick quenching chamber and cooling chamber, the water-cooled wheel shaft is sealingly fastened in the vacuum quick quenching chamber, the discharging opening of vacuum induction melting chamber is corresponding with the pour spout of melting kettle, and be communicated with fast quenching chamber charging aperture, between discharging opening and the charging aperture separation valve door is arranged, insulation crucible in the fast quenching chamber and bearing flexibly connect, keep its overfall to take turns cylinder and keep the fast quenching spacing over against water-cooled, the discharging opening of below, fast quenching chamber is communicated with cooling chamber, the centre is a separation valve door, and there is discharging opening the cooling chamber below.
The purpose of this utility model can also reach by following measure: bearing by base and on chassis and two spacing side plates form, arc stopper slot on the two spacing side plates is corresponding with the arc-shaped rack of the outer ancient piece of jade, round, flat and with a hole in its centre of insulation crucible, and be meshed with driven wheel, the insulation crucible is mobile in can the arc stopper slot on side plate by two pairs of bolsters; Cooling chamber is an intermediate water cooling storage tank, and the conical discharge port of bottom is equipped with separation valve door; Base is provided with the chassis and adjusts bolt; The charging aperture top of vacuum induction melting furnace chamber is for driving the pawl feeder.
The utility model is compared prior art and is had following advantage:
Technology is simple, easy operating, batching is through melting, directly enter fast quenching chamber fast quenching, the quick cooling ingot casting after the smelting technology, ingot casting fragmentation and screening operation have been exempted, the electric energy that secondary heating when both having saved fast quenching need consume, reduce working chamber's cold water ingot mould device and cooling system, reduce two operations and two equipment, simplified the labyrinth of former quick quenching furnace, also guaranteed the stability of technological parameter, avoid the environment of burning in the production process and sneaking into of foreign material, guaranteed product quality.Melting and fast quenching can carry out at the same time or separately, have improved the efficient of producing greatly.Vacuum induction melting chamber charging aperture top drive the pawl feeder, realize that high temperature is reinforced.
Description of drawings: Fig. 1 is the utility model structure chart;
Fig. 2 is crucible seat structure figure;
Fig. 3 is spacing lateral plate structure figure.
The utility model is described further below in conjunction with accompanying drawing:
As shown in Figure 1: the vacuum induction quick quenching furnace comprises intermediate frequency vacuum induction melting chamber, fast quenching chamber, cooling chamber.There is out pawl feeder (21) charging aperture top, induction melting chamber (1), the discharging opening (3) of working chamber (1) is corresponding with melting kettle (2) pour spout and be communicated with fast quenching chamber charging aperture (5), between discharging opening (3) and the charging aperture (5) separation valve door (4) is arranged, insulation crucible (6) in the fast quenching chamber flexibly connects with bearing (7), its overfall (8) is over against being sealingly fastened in the water-cooled wheel cylinder (9) in the vacuum quick quenching chamber and keeping the fast quenching spacing, fast quenching chamber discharging opening (3) is communicated with intermediate water cooling storage tank cooling chamber (12), and there is separation valve door (11) centre; The conical discharge port of cooling chamber (12) bottom is equipped with separation valve door (13).
As shown in Figures 2 and 3: bearing (7) is fixed in the fast quenching chamber, is made up of base (14) and chassis (15) and two spacing side plates (16).The action of toppling over of insulation crucible (6) realizes by the arc-shaped rack (18) of driven wheel (19) engages fixed on crucible: insulation crucible (6) is hung in the stopper slot of biside plate (16) by diaxon (17) supporting, the arc stopper slot on the biside plate (16) be incubated crucible (6) outside the arc-shaped rack (18) of an ancient piece of jade, round, flat and with a hole in its centre corresponding and be meshed with driven wheel (19), the rotation of realization crucible is located.Mesh when the driven wheel rotation and with the arc-shaped rack that is fixed on the crucible, crucible (6) is toppled over; The overfall of the insulation crucible (6) in the fast quenching chamber is realized with the position limiting structure that the fast quenching spacing adjustment of rotating water-cooled wheel cylinder (9) is at a high speed gone up biside plate by adjustment bolt (20) on the bearing (7) and base (14): adjustment bolt (20) movable chassis (15) on the base (14) also drags insulation crucible (6) translation location; Thereby can guarantee the fast quenching operation.
