Abstract
The utility model relates to a heating box of a powder metallurgy sintering furnace. The heating box comprises a heating box support, graphite partition plates, ceramic plates and a door frame, wherein the heating box support is arranged in a box body, and a plurality of slots are arranged on the inner wall of the heating box support at fixed interval and the slots on the two sides are opposite; the graphite partition plates are inserted in the slots, and a plurality of ceramic plates are overlayed on the upper side of each graphite partition plate; and the outer side of the heating box support is provided with the door frame, the upper side and the lower side of the door frame are respectively provided with a groove, and the depth of an upper part frame body is greater than that of a lower frame body. The heating box provided by the utility model has beneficial effects that the slots and the graphite plates and the ceramic plates which are matched with the thickness of slotted holes are arranged, the structure in the box can be adjusted by timely adjusting the graphite plate and the ceramic plate so as to lead the size of a metallurgy product to match with the heating space; and the heating is uniform, the sealing property of a door plate is good, and the defect of the higher defective rate is avoided.
Description
Technical field
The utility model relates to powder metallurgy burning techniques field, relates in particular to a kind of heating cabinet of powder metallurgy sintering furnace.
Background technology
Used sintered metal product sintering furnace mainly contains two kinds at present, and a kind of is vacuum sintering furnace, and another kind is an overpressure sintering furnace.Vacuum sintering furnace around exothermic material is housed; Overpressure sintering furnace then about and the bottom exothermic material is housed; These two kinds of sintering furnaces are in carrying out the hard metal article sintering process; The heating degree at each position to some extent need not, critical defects such as density gradient, hardness gradient, intensity gradient, magnetic gradient, bonding phase skewness appear in product internal organizational structure and each item physical performance index, also cause the gross distortion of product geometry simultaneously; Greatly influence the serviceability and the life-span of goods hart metal products, thereby reduced the qualification rate that carbide alloy is made; In addition, owing to receive the volume restrictions of smelting goods, the general layout setting of furnace internal-lining can't adapt to its size fully, has perhaps wasted space resources to a certain extent.
The utility model content
To above defective; The purpose of the utility model provides and a kind ofly is heated evenly, sealing property better, have a heating cabinet of the powder metallurgy sintering furnace of insertion slot type structure; Through being set, insertion slot type chamber plate realizes general layout in the timely adjusting tank, to reach the purpose that metallurgical product volume and heating space are complementary.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of heating cabinet of powder metallurgy sintering furnace; Comprise heating cabinet support, graphite septum, ceramic wafer and doorframe; Box house is provided with the heating cabinet support, and the inwall of the said heating cabinet support slot position separately that constant spacing is provided with a slot and two side that whenever is separated by is corresponding; Insert graphite septum in the said slot, the upside of every graphite septum stacks some ceramic wafers; The arranged outside doorframe of said heating cabinet support, the both sides up and down of doorframe are offered groove respectively, and the degree of depth setting of top framework groove is greater than the lower frame body groove depth.
The beneficial effect of the heating cabinet of the described powder metallurgy sintering furnace of the utility model is: through graphite cake and the ceramic wafer that slot is set and is complementary with its slotted eye thickness, pull comes general layout in the adjusting tank so that metallurgical product volume and heating space are complementary timely; Be heated evenly, the door-plate favorable sealing property, avoided the higher defective of defect rate.

Fig. 1 is the structural representation of the heating cabinet of the described powder metallurgy sintering furnace of the utility model embodiment;
Fig. 2 is the hermatic door sketch map of the heating cabinet of the said powder metallurgy sintering furnace of the utility model embodiment.
Among the figure:
1, casing; 2, heating cabinet support; 3, graphite septum; 4, ceramic wafer; 5, slot; 6, doorframe; 7, door body; 8, groove.
The specific embodiment
As shown in Figure 1; The heating cabinet of the described powder metallurgy sintering furnace of the utility model; Comprise heating cabinet support 2, graphite septum 3, ceramic wafer 4 and doorframe 6; Be provided for the heating casing of powder metallurgy heating in the heating furnace, the heating cabinet support 2 that casing 1 set inside is made up of housing, base and some dividing plates, the inwall of said heating cabinet support 2 constant spacing of whenever being separated by is provided with the slot 5 position correspondence separately of a slot 5 and two side; Insert graphite septum 3 in the said slot 5, the upside of every graphite septum 3 stacks some ceramic wafers 4; The arranged outside doorframe 6 of said heating cabinet support 2; The both sides up and down of doorframe 6 are offered groove 8 respectively and are used for inserting door body 7 to keep good sealing property, and the degree of depth setting of top framework groove 8 makes door body 7 insert groove 8 backs greater than the lower frame body groove depth and in groove, leaves enough spaces so that unload Xiamen body 7.
