Embodiment 1
Fig. 1 is please referred to, Fig. 1 show the structural schematic diagram of autoclave 100.The present embodiment provides a kind of autoclaves 100, main
It is used to carry out hot-press solidifying molding to material.
Autoclave 100 includes tank body 110 and the end socket 150 and cover 170 that are respectively arranged at 110 both ends of tank body, cover
170, tank body 110 and end socket 150 are sequentially connected.End socket 150 is used for closed tank 110, and cover 170 is used to open or closing tank
Body 110.
The inner wall 112 of tank body 110 forms hot pressing chamber 114, and end socket 150 is for closing hot pressing chamber 114, and cover 170 is for beating
Open or close hot pressing chamber 114.Tank body 110 is also equipped with heating system, and heating system includes the heating plate being installed on inner wall 112
116.Heating plate 116 is generally only installed on the side on inner wall 112, and heating plate 116 is installed on hot pressing chamber 114 in the present embodiment
Top.
Since hot pressing chamber 114 is the place that material carries out curing molding, it is equipped with guide rail in the bottom of inner wall 112
118, it is slid by guide rail 118 convenient for materials vehicle, saves manpower.In general, heating plate 116 is just installed on above materials vehicle, i.e.,
The top of guide rail 118, that is, hot pressing chamber 114 shown in FIG. 1 top.Fig. 2 is please referred to, is that transport vehicle 102 slides into shown in Fig. 2
The structural schematic diagram of autoclave 100 after hot pressing chamber 114.Material 104 is placed in 102 top of transport vehicle, opposite with heating plate 116.Object
The top of material 104 is since close to heating plate 116, it is heated most, it is heated more closer to the side of transport vehicle 102 for material 104
It is few.And upper materials 104 can only be relied on to transmit heat substantially close to the material 104 of transport vehicle 102, cause upper materials
104 curing degrees are excessive, and 104 curing degree of lower layer's material is too small, and eventually leading to moulding material cannot be by the cure parameter of design
Solidification.
To solve the above problems, please referring to Fig. 3, Fig. 3 show the structural schematic diagram of guide rail 118 and heat sink 120.Guide rail
118 include the first guide rail 122 and the second guide rail 124 being oppositely arranged, and heat sink 120 is installed on inner wall 112 and is led positioned at first

The other end is connect with heating plate 116, and the heat of heating plate 116 is timely transmitted to heat sink 120.Adjacent with guide rail 118
Inner wall 112 on heat sink 120 is set, can increase the heated uniformity of material.The difference of 120 specific location of heat sink,
It is slightly different to the contribution of being heated evenly property of material.When transport vehicle 102 is located on guide rail 118,104 lowest level of material just with
Heat sink 120 is opposite, and heat sink 120 can preferably be that undermost material 104 provides heat at this time.
Heat conducting pipe 126 includes heat-conducting layer and thermal insulation layer, and internal layer is heat-conducting layer, and outer layer is thermal insulation layer, and thermal insulation layer is by heat-conducting layer
Package.Heat-conducting layer one end is connect with heating plate 116, and the other end and heat sink 120 connect.Heat-conducting layer is mainly responsible for heat conduction, heat-insulated
Layer can prevent heat-conducting layer from occurring a large amount of heat loss in conduction process.
In order to realize better heat-conducting effect, the heat of heating plate 116 is set quickly to be directed on heat sink 120, heat-conducting layer master
It will be using graphite or graphene as Heat Conduction Material, naturally it is also possible to the mixture for both being.The thermal conductivity of graphite be more than steel, iron,
The metal materials such as lead, and it is cheap.Graphene is presently found most thin, maximum intensity, electrical and thermal conductivity performance strongest one
Kind novel nano-material, but price is relatively expensive, therefore the mixture of graphite and graphene can be selected as main heat conduction material
Material.The setting can better ensure that the Synchronous Heating of 104 the upper and lower of material, improve the being heated evenly property of material 104.Every
Thermosphere, to block the transmission of hot-fluid radially in heat conducting pipe 126, makes hot-fluid faster such as can select asbestos, glass fibre
Reach heat sink 120.
The quantity of heat conducting pipe 126 can be selected as the case may be, such as can be 3,6 etc., the present embodiment
It is not especially limited.
Cover 170 is rotatably connected with tank body 110, convenient for opening or closing hot pressing chamber 114.Fig. 4 is please referred to, shown in Fig. 4
Structural schematic diagram when being opened relatively for cover 170 and tank body 110.When cover 170 is opened for a long time, it is possible that cover 170
The case where tenesmus.The lid of cover 170 is closed when on tank body 110 again, can not directly be directed at the opening of tank body 110, it is necessary to rely on
The place of dislocation is aligned by external force with the opening of tank body 110, considerably increases the operation difficulty of operating personnel.It is asked to solve this
Topic is provided with supporting rod 128 on tank body 110.When cover 170 and tank body 110 are opened relatively, the bottom of cover 170 is just
On supporting rod 128, supporting rod 128 plays a supportive role to cover 170, prevents cover 170 under the gravity of its own
It drops.
The structure being not specifically mentioned in the present embodiment please refers to hot pressing jar structure purchased in market.Such as autoclave purchased in market is generally also
Including blower fan system, compression system, exhaust system, vacuum system, cooling system, automatic control system etc..
The operation principle of autoclave 100 is：
Cover 170 is opened, the transport vehicle 102 with material 104 is pushed into heat by the first guide rail 122 and the second guide rail 124
It presses in chamber 114.The related work system for opening autoclave 100 sets relevant work parameter, and the hot pressing for starting material 104 is solid
Change.Thermal convection current is directly carried out between the heating plate 116 and upper materials 104 of 104 top of material.The temperature of heating plate 116 is once
Start to increase, hot-fluid will be timely transmitted to by heat conducting pipe 126 on heat sink 120.Heat sink 120 and 104 phase of lower layer material
Right, the two can directly carry out thermal convection current, substantially increase the heating rate of lower layer's material 104, to make material 104 it is whole by
Heat evenly, makes the solidification rate at 104 each position of material reach unanimity.
The present embodiment also provides a kind of Aircraft Production equipment, including autoclave 100.It can improve each parts of aircraft
The quality of production reduces the difference of the actual mass parameter and preset quality parameter of each product.
