Abstract
The utility model discloses a vacuum furnace capable of quickly cooling down, which comprises a furnace body, an inner furnace door, an outer furnace door, an inner furnace door opening and closing transmission mechanism and a guide column; the outer furnace door is a double-layered water cooling structure; the inner furnace door is made of fireproof heat preserving material; the outer furnace door is made of the same material with the furnace body; and the inner furnace door is inlaid and installed in the inner layer of the outer furnace door. Through the design of the inner and outer furnace door structure, the inner furnace door is closed during the heating process, so that the heating performance of the vacuum furnace is not affected; after the heating is over and the work pieces in the furnace need to be cooled, the inner furnace is opened, so as to quickly cooling the work pieces in the furnace; and meanwhile, the quality of work piece heating is not affected, the structure is simple and the implementation cost is low.
Description
Technical field
The utility model relates to a kind of vacuum drying oven, particularly a kind of vacuum drying oven that can cool off fast.
Background technology
Existing vacuum electric furnace is in heating process, and in order to reach using electricity wisely and to add thermal effect purpose preferably, the heat insulation effect of furnace chamber is reasonable.But the furnace chamber high insulating effect causes finishing in heating, and cooling rate was very slow when the workpiece that heating is finished in the stove need be lowered the temperature, and had a strong impact on the device fabrication operating efficiency.Because under the condition of high temperature, if directly open the fire door heat radiation, airborne oxygen will enter body of heater, cause high-temperature device to be caused damage by rapid oxidation.And existing acceleration radiating mode mainly is by charging into inert gas in furnace chamber, and makes it to circulate, and the shortcoming of this mode is that gas consumption is big, the use cost height.
The utility model content
For solving above-mentioned existing in prior technology technical problem, it is a kind of simple in structure that the utility model provides, and implementation cost is low, can realize the vacuum drying oven of device fast cooling after heating finishes in the stove.
The scheme that the utility model solves the problems of the technologies described above is: a kind of vacuum drying oven that can cool off fast, comprise flue 1, interior fire door 2, outer fire door 3, interior fire door folding transmission mechanism 4, lead 5 and body of heater 6, described outer fire door 3 is double-deck water-cooling structure, interior fire door 2 is made for flame-proof thermal insulation material, outer fire door 3 is made for the metal material identical with the body of heater surface, outer fire door 3 is installed on the body of heater 6, fire door 2 embeds and is installed on outer fire door 3 internal layers in described, fire door folding transmission mechanism 4 is a rack-and-pinion type transmission mechanism in described, described tooth bar 7 is fixed on the outer fire door 3, described gear 8 is connected by jockey 9 with an end of lead 5, and the other end of described lead 5 passes outer fire door 3 and vertically is connected on the interior fire door 2.
In the utility model, lead 5 seals by rubber-like ripple sealed tube 10.
Technique effect of the present utility model is: by the design of inside and outside door structure, make the heating properties of vacuum drying oven unaffected, and when workpiece need cool off in the stove after heating finishes, fire door folding transmission mechanism and lead interlock in can utilizing, fire door outwards moves in making fast, thereby, furnace chamber and interior fire door are thrown off, and then utilize the thermal conductive resin and the extraneous space of the metal shell of outer fire door to realize heat exchange, reach the purpose of workpiece in the quick cool furnace, can not influence simultaneously the quality of heated parts, and simple in structure, implementation cost is low.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, outer fire door 3 is installed on the body of heater 1, and interior fire door adopts with the inner identical insulation material of body of heater and makes, and 3 at outer fire door is the metal material identical with the body of heater outer surface, outer fire door 3 can outwards be opened, and closes the salable whole body of heater 1 in back to play the effect of insulation.Interior fire door 2 is embedded on the internal layer of outer fire door 3, and in an end of lead 5 vertically is connected on the fire door 2, the other end passes outer fire door 3 and exposes to body of heater 1 and by the gear 8 of jockey 9 with interior fire door folding transmission mechanism 4 and be connected.Lead 5 seals by rubber-like ripple sealed tube 10, and the workpiece that can effectively prevent heating in the stove like this contacts with extraneous air and produces oxidative phenomena, has guaranteed the quality that heats.The gear 8 of interior fire door folding transmission mechanism 4 is meshed with tooth bar 7, and tooth bar 7 is fixed on outer fire door 3 outer surfaces.When device heats in the stove finishes need cool off the time, promptly turn the gear 8 of folding transmission mechanism, gear 8 rotates, drive lead 5 to flue 1 outside moving by jockey 9, interior fire door 2 is outside mobile to flue 1 by the transmission of lead 5, make furnace chamber and interior fire door throw off, because the outer surface of outer fire door 3 is that metal is made, and the thermal conductivity of metal is better, heat in the stove carries out heat exchange by outer fire door outer surface and space outerpace, can play good thermolysis, outer fire door still is in closed condition simultaneously, can not cause the high-temperature device in the stove owing to contact and oxidized phenomenon with oxygen.The cooling rate of faster devices is enhanced productivity so effectively.
