Description
Technical field
The utility model relates to the structure of the door of the peristome that is located at atmosphere sintering furnace.
Background technology
In reducing atmosphere in keeping stove or the non-oxidizing atmosphere workpiece is carried out in the atmosphere sintering furnace of sintering; In order to prevent that extraneous gas from getting in the stove; Dispose atmosphere displacement chamber in abutting connection with ground with peristome; And the door of atmosphere sealing usefulness is set, between peristome and atmosphere displacement chamber with sealed open portion.
For example shown in the patent documentation 1 (TOHKEMY 2009-216257 communique), the door of this atmosphere sealing usefulness normally possesses the elevating mechanism that is used to open and close and is used for the door of door to the retention mechanism of peristome pushing.Therefore, it is complicated that structure becomes, thereby become the reason that cost improves.
The utility model content
Therefore, the purpose of the utility model is to solve above-mentioned former problem points, when providing simple in structure can with the former door of the atmosphere sintering furnace of sealed open portion reliably likewise.
The utility model that proposes in order to solve above-mentioned problem is characterised in that; Be constructed as follows structure; The framework of utilizing cylinder to go up and down in the arranged outside of the peristome of atmosphere sintering furnace along this peristome; And utilize the parallel linkage that extends below tiltedly from case side that the door of the atmosphere sealing usefulness parallel with above-mentioned peristome is installed in this framework, through this lower end with further make framework decline after the traverse feed roller of bottom surface contacts, make this be close to the peristome of atmosphere sintering furnace.
The utility model preferred embodiment in, the peristome of above-mentioned atmosphere sintering furnace is located at furnace chamber and is adjacent between the atmosphere displacement chamber of furnace chamber, and above-mentioned parallel linkage is configured in four positions up and down of door.
The effect of the utility model is following.
In the door of the atmosphere sintering furnace of the utility model, only descend through the framework of utilizing cylinder to make to be equipped with the door of atmosphere sealing usefulness, just can close door and can also make a peristome that is close to atmosphere sintering furnace.In addition, on the contrary, only through utilizing cylinder that framework is risen, the releasing that just can seal is opened with door.Therefore, unlike the elevating mechanism that need be provided for respectively in the past opening and closing be used for the retention mechanism of door to peristome pushing, just can guarantee sealing reliably, and can realize the cost reduction.

Fig. 4 is the enlarged drawing of the bottom of door.
Among the figure:
The 1-body of heater, 2-peristome, 3-furnace chamber, 4-atmosphere displacement chamber, the door of 5-atmosphere sealing usefulness; The 6-cylinder, 7-framework, 8-vertical rod, 9-door receiving room, 10-top plate portion; The 11-sleeve, 12-piston rod, 13-tie-beam, 14-parallel linkage, 15-attachment pegs; The 16-attachment pegs, 17-bottom surface, 18-traverse feed roller, 19-butt parts, 20-access panel.
The specific embodiment
The embodiment of the utility model is described below.
In Fig. 1, Reference numeral 1 is the body of heater of atmosphere sintering furnace, and Reference numeral 2 is its peristomes, and Reference numeral 3 is furnace chambers.The stove of this embodiment is continuous ovens such as roller kilns or pushed bat kiln, and peristome 2 is located at two positions of entrance side and outlet side.In addition, be provided with atmosphere with furnace chamber 3 in abutting connection with ground and replace chamber 4.
With likewise in the past, poured into atmosphere gas in the inside of body of heater 1, utilize not shown heating arrangements to heat in addition.Atmosphere gas for example is a nitrogen, and heating arrangements for example is infrared heater, radiant tube, SiC heater etc.And, self-evident, be sintered thing or take out from furnace chamber 3 that atmosphere gas also can supply to atmosphere displacement chamber 4 when being sintered thing packing into to furnace chamber 3.
Above-mentioned peristome 2 is sealed by the door 5 of atmosphere sealing usefulness, moves into the inside of furnace chamber 3 or sinter is taken out of under the situation stove outside at the article that will be sintered, and need make 5 rising, opens peristome 2.Therefore, the door of explanation below the employing in the utility model.
Between body of heater 1 and atmosphere displacement chamber 4, be provided with the framework 7 of going up and down by cylinder 6.As shown in Figure 3, this framework 7 is the big large-scale quadrangle forms of ratio open portion 2, about it, possess to above the vertical rod 8 that extends.Between body of heater 1 and atmosphere displacement chamber 4, be formed with a receiving room 9, vertical rod 8 connects the sleeve 11 on the upper surface of the top plate portion 10 that is located at a receiving room 9.In addition, the bottom of cylinder 6 also is supported on the upper surface of top plate portion 10 of a receiving room 9.The upper end of the piston rod 12 of cylinder 6 is connected the central authorities of tie-beam 13, and the upper end of vertical rod 8 also is connected the two ends of this tie-beam 13.
Therefore, if the piston rod 12 of elongation cylinder 6, then tie-beam 13 is got on by the top, because vertical rod 8 is raised, framework 7 rises to the inside of a receiving room 9 as illustrated in fig. 1.In addition, if the piston rod 12 of withdrawal cylinder 6, then tie-beam 13 reduces, and vertical rod 8 is depressed, so framework 7 descends as illustrated in fig. 2.And door receiving room 9 is hermetically-sealed constructions, also can not get into even sleeve 11 is produced the slip extraneous gas by air seal one-tenth vertical rod 8.
The door 5 of atmosphere sealing usefulness is supported on peristome 2 sides of this framework 7 by parallel linkage 14.Like Fig. 1, shown in Figure 2, the attachment pegs 15 that parallel linkage 14 makes framework 7 sides always is positioned at higher position than the attachment pegs 16 of door 5 sides and extends to oblique below from case side.As shown in Figure 3, in this embodiment, parallel linkage 14 is configured in four positions up and down of door.
As shown in Figure 4, when door 5 descends along with framework 7 together, on the lower end of door 5 and bottom surface 17 position contacting, be provided with traverse feed roller 18.This traverse feed roller 18 contacts with the butt parts 19 of the lower end that is located at door 5, has the effect to horizontal direction moving door 5.
The effect of the door of explanation the utility model below.Be sintered thing or when furnace chamber 3 takes out sinters packing into to furnace chamber 3, make in advance atmosphere in the atmosphere displacement chamber 4 identical with atmosphere in the furnace chamber 3 after, utilize cylinder 6 to make 5, thereby open peristome 2 along with framework 7 rises to the inside of a receiving room 9 together.Under this state, door 5 is positioned at than framework 7 to sagging position, oblique below because of deadweight.Under this state, through peristome 2, the taking-up that can be sintered thing is put into.
After the taking-up that finishes to be sintered thing is put into, utilize cylinder 6 that framework 7 is descended.Door 5 is also along with framework 7 descends together, and the butt parts 19 that are located at the lower end of door 5 are run into the traverse feed roller 18 of bottom surface 17, can not further descend.If from this state framework 7 is descended a little, then the attachment pegs 15 of parallel linkage 14 is pressed and the angle of inclination of parallel linkage 14 diminishes as illustrated in fig. 13, and according to the principle of linkage, 5 are urged to peristome 2 powerfully.Can carry out the sealing of peristome 2 reliably thus.
During peristome 2 is so sealed, begin common atmosphere sintering once more.And, if form access panel 20, the situation that then can also observe the inside of furnace chamber 3 at door 5 as illustrated in fig. 3.
As above illustrated, the door of the atmosphere sintering furnace of the utility model is only through utilizing cylinder 6 to make framework 7 go up and down just can carry out a lifting action of 5 and to the racking of peristome 2.Therefore, unlike in the past elevating mechanism and retention mechanism being set respectively, just can realize that cost reduces.And the power of thrust door 5 is powerful, can carry out the sealing of peristome 2 reliably.
