Detailed Description

The present application is described in further detail below with reference to figures 2-5.

The embodiment of the application discloses a sintering furnace. Referring to fig. 2, the sintering furnace includes a furnace body 1, an automatic furnace door 4 for limiting the internal temperature loss of the furnace body 1, and a vacuum pump 3 for controlling the vacuum degree in the furnace body 1. The automatic furnace door 4 is fixedly connected with the feeding end of the furnace body 1, the vacuum pump 3 is fixedly connected with the peripheral surface of the furnace body 1, and the air exhaust end of the vacuum pump 3 is communicated with the cavity in the furnace body 1.

Referring to fig. 2 and 3, the automatic furnace door 4 includes a door frame 5 disposed at a feeding end of the furnace body 1, a driving member 6 disposed on the door frame 5, and a door body 7 disposed at a driving end of the driving member 6, and the door body 7 is slidably connected in the door frame 5 under the action of the driving member 6.

Specifically, the sliding groove 8 has been seted up to one side that door frame 5 is close to driving piece 6, and one side that door frame 5 kept away from furnace body 1 runs through the feed chute 9 of seting up with the mutual intercommunication of feed end of furnace body 1, and feed chute 9 communicates with the sliding groove 8 each other, and the groove width of feed chute 9 is less than the groove width of sliding groove 8. The furnace door 2 slides in the sliding groove 8 in a reciprocating manner under the driving of the driving part 6, so that the door body 7 is enabled to cover or open the feeding groove 9, the groove wall of the sliding groove 8 limits the movement of the door body 7, and the possibility of separation of the door body 7 from the door frame 5 is reduced.

With continued reference to fig. 2 and 3, in this embodiment, the door frame 5 is fixedly attached to the feed end of the furnace body 1, and the driving member 6 is fixedly attached to the upper end of the door frame 5. In other embodiments, the fixed connection may be a conventional connection such as a detachable connection, and the driving member 6 may be disposed on other side walls of the door frame 5. In addition, in the present embodiment, the driving member 6 is an air cylinder, and in other embodiments, the driving member 6 may also be a conventional driving device such as an oil cylinder and a lead screw

In this embodiment, the door body 7 can be dismantled and connect in the drive end of driving piece 6, and is concrete, and one side fixedly connected with connector 10 that the door body 7 is close to driving piece 6, and connector 10 can be dismantled with the drive end of driving piece 6 and be connected, and then makes the door body 7 appear when damaged because long-time the use, can directly change the door body 7. It should be noted that the detachable connection may be a conventional detachable connection manner such as a threaded connection, a bolt fastening, an interference connection, and the like. In other embodiments, the connection mode of the door 7 and the driving member 6 may be a conventional connection mode such as fixed connection,

referring to fig. 3, it is easy to see that when the door 7 is slidably connected in the sliding groove 8, a gap is easily formed between the door 7 and the door frame 5, and the sealing effect of the automatic oven door 4 on the oven body 1 is slightly poor.

Therefore, in the present embodiment, the door frame 5 includes a frame 11 and an elastic gasket 12 provided in the frame 11. Specifically, inserting groove 13 has been seted up to one side that framework 11 is close to driving piece 6, and elastic sealing gasket 12 pegs graft in inserting groove 13, and sliding groove 8 sets up in one side that elastic sealing gasket 12 is close to driving piece 6 for elastic sealing gasket 12 can seal the clearance between framework 11 and the door body 7, and then effectively improves the sealed effect of automatic furnace door 4 to furnace body 1.

In addition, in the present embodiment, the elastic gasket 12 is made of a flexible graphite fiber mat, and the flexible graphite fiber mat has high temperature resistance, so that the elastic gasket 12 reduces the influence of temperature on the sealing property when sealing the door body 7 and the frame body 11.

With continued reference to fig. 3 and 4, in order to further improve the sealing performance of the elastic sealing gasket 12 between the frame body 11 and the door body 7, the two side walls of the door body 7 are fixedly connected with the limiting frames 14, and one side of the limiting frame 14 away from the door body 7 is provided with a guide surface 15. In the present embodiment, the guide surface 15 has an arc shape, and the arc-shaped guide surface 15 always abuts against the groove wall of the slide groove 8. In other embodiments, the guide surface 15 may be an inclined surface gradually approaching the door 7 in a direction away from the driver 6.

When the limit frame 14 is positioned in the sliding groove 8, the limit frame 14 forces the elastic sealing gasket 12 to deform, so that the possibility of generating a gap between the elastic sealing gasket 12 and the limit block is effectively reduced, and the sealing effect of the furnace door 2 on the furnace body 1 is further improved. When the limiting frame 14 needs to slide into the sliding groove 8, the guide surface 15 can provide a guide force to the elastic sealing gasket 12, so that the elastic sealing gasket 12 is forced to deform.

With reference to fig. 3, in order to slide the door 7 into the sliding groove 8 more easily, a pre-positioning portion 16 is fixedly connected to a side of the door 7 away from the driving member 6, in this embodiment, the pre-positioning portion 16 is a triangular prism, and in other embodiments, the pre-positioning portion 16 may also be a cone, a triangular cone, or the like having a tip portion.

When the door body 7 needs to slide into the sliding groove 8, the pre-positioning part 16 forces the elastic sealing gasket 12 to deform, and then the door body 7 can completely slide into the sliding groove 8, so that the door body 7 is simpler and more convenient to install.

Referring to fig. 3 and 5, it can be easily seen that the elastic gasket 12 is easily carried out by the door 7 when the door 7 reciprocally slides in the sliding groove 8. Therefore, in order to improve the connection stability between the elastic sealing gasket 12 and the frame body 11, the side of the frame body 11 close to the driving element 6 is detachably connected with a plurality of limiting plates 17, and the side of the elastic sealing gasket 12 close to the driving element 6 is abutted against the side of the limiting plate 17 far away from the driving element 6, so that the limiting plates 17 limit the elastic sealing gasket 12, and the possibility of the elastic sealing gasket 12 being separated from the frame body 11 is reduced.

Specifically, one side of the frame body 11 close to the driving member 6 is in threaded connection with a plurality of limiting bolts 18, one side of the limiting plate 17 close to the driving member 6 is provided with a limiting hole 19 in a penetrating manner, and the limiting bolts 18 penetrate through the limiting hole 19 and are in threaded connection with the frame body 11. So that the elastic sealing gasket 12 can be directly replaced when the elastic sealing gasket 12 is deteriorated due to a long-term use.

In this embodiment, the number of the limiting plates 17 is two, the two limiting plates 17 are respectively disposed on two sides of the frame 11, the number of the limiting bolts 18 is four, and the four limiting bolts 18 are respectively disposed on the two limiting plates 17, so that the limiting effect of the limiting bolts 18 on the limiting plates 17 is effectively improved.
