Abstract
The utility model discloses a vacuum sintering device, which can organically combine the high temperature sintering process and the quick cooling process together. One side of a furnace body is provided with a quick cooling jetting cover, and the bottoms of the furnace body and the quick cooling jetting cover are provided with orbits and roller ways. The base plate of the roller way is connected with a rotary lift mechanism. During cooling process, the furnace body and the quick cooling jetting cover are shifted mutually, and the base plate of the roller way can be controlled by the lift mechanism for supporting the muffle tank body. The quick cooling jetting cover is evenly provided with nozzles along the radical direction and the longitudinal direction for cooking the muffle tank body uniformly.
Description
The utility model relates to a kind of vacuum-sintering device, particularly is used for the device of sintered magnetic material.
The sintering of magnetic material (especially neodymium iron boron), its technology generally need satisfy vacuum outgas, high temperature sintering and the requirement of cooling fast, otherwise sintering quality will be difficult to guarantee.
In order to address this problem, the common practice is carried out vacuum outgas and high temperature sintering in equipment after, with manpower with the Muffle pot body by extracting out in the burner hearth, it is dropped into fast in cold water, to satisfy the requirement of cooling fast.Because the difference of Muffle pot body entry precedence causes its distortion, particularly vacuum outgas and high-temperature sintering process still can not organically combine with quick cooling procedure, still influences sintering quality.
The purpose of this utility model is that a kind of improved vacuum-sintering device will be provided, and this device can make high temperature sintering and quick cooling procedure organically combine.
The purpose of this utility model is achieved in that the side at the device body of heater is provided with quick cooling injection cover, bottom at quick cooling injection cover and body of heater is provided with track and roller-way, body of heater and quick cooling injection cover can be realized mutual displacement along track, roller-way chassis and one is rotated elevating mechanism and is connected, after sintering finishes, quick cooling injection cover is pushed into the body of heater position, immediately body of heater is drawn out to the original position of quick cooling injection cover along roller-way, rotate elevating mechanism simultaneously, make the roller-way chassis support the Muffle pot body, radially reach the cooling water that vertically evenly is arranged on the nozzle ejection in the quick cooling injection cover, can make the Muffle pot body realize spraying fast uniformly cooling.
The utility model is owing to organically combine body of heater and quick cooling injection, thereby can be by means of the dynamic pressure increment of spraying cooling water, around the Muffle pot body, cause bigger thermograde field boundary, simultaneously, because nozzle radially reaches and vertically is periphery around the Muffle pot body, thereby can make the Muffle pot body obtain cooling equably.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 1 is the utility model structural representation.
Fig. 2 is the left pseudosection of Fig. 1 along the B-B line.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
This device supports body 3 and resistive band 4 to be built into body of heater integral body by furnace shell 1, furnace lining 2, electric heating element, furnace shell 1 is by hot rolled steel plate weldering system, its inboard furnace lining 2 is made of light-weight refractory clay product, alumina silicate felt and the glass fibre cotton of moulding, the nexine of furnace lining 2 is that electric heating element is supported body 3, in supporting body 3, electric heating element is provided with ribbon heater 4 equably, body of heater integral body is chorista with Muffle pot body 5 and vacuum seal cover 10, when body of heater when the track of framework 7 and roller-way are pulled out, Muffle pot 5 and vacuum seal cover 10 and closed furnace door 11 lockings.
Side in body of heater integral body is provided with quick cooling injection cover 6, radially reach at the quick inner surface of cooling injection cover 6 and vertically to be provided with nozzle 14 equably, bottom at quick cooling injection cover 6 and body of heater is provided with roller-way 7a and track 7b, and roller-way chassis 8a rotates elevating mechanism 8b control lifting by one.Be provided with argon gas air admission hole 12 in the left side of Muffle pot 5, be provided with waste gas porus excretorius 13 on the right side of Muffle pot body 5, vacuum system 9 communicates with Muffle pot body 5.Fire door 11 is positioned at the left side of Muffle pot 5.
After raw material (as neodymium iron boron) shove charge, with fire door 11 sealings, start vacuum system 9, and in Muffle pot 5, import argon gas by air admission hole 12, raw material carries out high temperature sintering, after the end to be sintered, quick cooling injection cover 6 is pushed into the body of heater position along track 7b, (this moment, the Muffle pot body 5 immediately body of heater to be drawn out to the original position of quick cooling injection cover 6 along roller-way 7a, fire door 11 and vacuum seal cover 10 are still in the original place), rotate elevating mechanism 8b simultaneously, make roller-way chassis 8a support Muffle pot body 5, then rapidly by quick cooling injection cover 6 make cooling water be injected in quickly and evenly Muffle pot body 5 around, after the temperature in the Muffle pot 5 was chilled to 300 ℃, pine was unloaded fire door 11, and product is taken out.
Claims (2)
1, a kind of vacuum-sintering device comprises body of heater, Muffle pot body and fire door, it is characterized in that being provided with quick cooling injection cover in one of body of heater side, is provided with track and roller-way in the bottom of quick cooling injection cover and body of heater, and roller-way chassis and is rotated elevating mechanism and connected.
2, device according to claim 1 is characterized in that radially reaching on the said quick cooling injection cover and vertically is provided with nozzle equably.
