Abstract
The utility model relates to a kind of vacuum sintering furnace, comprise vacuum chamber, described vacuum chamber outer setting exocoel vacuumized, described vacuum chamber outer surface arranges heat-insulation layer, described exocoel outer surface water-cooled layer, and described exocoel top arranges upper cover, by Flange joint cavity of resorption below vacuum chamber, arrange apparatus for detecting pressure respectively in described vacuum chamber and exocoel, apparatus for detecting pressure connection control system, control system connects vacuum extractor.After adopting such structure, vacuum sintering furnace of the present utility model can realize the requirement of two-chamber high low vacuum with a set of vacuum pump set, improves the service life of vacuum chamber.
Description
Technical field
The utility model relates to a kind of magnetic material treatment facility, for the vacuum-sintering of magnetic material.
Background technology
The vacuum-sintering of the magnetic materials such as SmCo, conventional sintering processing is placed on by magnetic material in the middle of a vacuum chamber, the mode vacuumized by vacuum pump set makes air molecule number in the middle of vacuum chamber in unit volume lower than certain number, reach certain vacuum, under vacuum conditions sintering processes is carried out to material.This processing mode, because internal vacuum chamber vacuum is very low, makes external pressure very large to the pressure of vacuum chamber.In technical process, vacuum chamber, when bearing high temperature and immense pressure, is especially easily out of shape, cracked.Affect the vacuum chamber life-span, increase production cost.
Utility model content
Problem to be solved in the utility model is to provide a kind of preventing in sintering process because of vacuum chamber sintering structure that inside and outside differential pressure causes too greatly vacuum chamber to be out of shape.
Vacuum sintering furnace of the present utility model, comprise vacuum chamber, described vacuum chamber outer setting exocoel vacuumized, described vacuum chamber outer surface arranges heat-insulation layer, described exocoel outer surface water-cooled layer, and described exocoel top arranges upper cover, by Flange joint cavity of resorption below vacuum chamber, arrange apparatus for detecting pressure respectively in described vacuum chamber and exocoel, apparatus for detecting pressure connection control system, control system connects vacuum extractor.
After adopting such structure, vacuum sintering furnace of the present utility model can realize the requirement of two-chamber high low vacuum with a set of vacuum pump set, improves the service life of vacuum chamber.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model vacuum sintering furnace.
Fig. 2 is the sectional view along A-A line in Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, vacuum sintering furnace of the present utility model, comprise vacuum chamber 1, the exocoel 2 that vacuum chamber 1 outer setting one vacuumizes, vacuum chamber 1 outer surface arranges heat-insulation layer 3, exocoel 2 outer surface water-cooled layer 4, exocoel 2 top arranges upper cover 5, connects cavity of resorption 7 below vacuum chamber 1 by flange 6, arranges apparatus for detecting pressure 8 respectively in vacuum chamber 1 and exocoel 2, apparatus for detecting pressure 8 connection control system 10, control system connects vacuum extractor 9.
In technical process, first exocoel 2 is vacuumized, again inner chamber vacuum chamber 1 is vacuumized after reaching certain vacuum, make vacuum chamber 1 inside and outside differential pressure very little, reduce deflection during high temperature, extend service life, improve the stability of warm area.Bonding pressure sniffer 8 in vacuum chamber 1 and exocoel 2; can pressure in Real-Time Monitoring vacuum chamber 1 and exocoel 2 when vacuumizing; pressure signal compares through control device; control the vacuum pumping rate of vacuum extractor 9; the pressure differential of vacuum chamber 1 and exocoel 2 can be guaranteed within the specific limits, can better protect vacuum chamber 1.
Claims (1)
