Description
Technical Field
The invention relates to a filling cabin, in particular to a large-size complex amorphous alloy component antigravity filling cabin.
Background
In the preparation process of the block amorphous alloy component in the prior art, except that the raw materials for forming the amorphous alloy have extremely high purity, a melting crucible and a casting mould, the environment involved in the preparation process is also a crucial factor. During the casting and forming process of the amorphous component, the invasion of all impurities such as unexpected elements and oxygen from the surrounding environment is strictly controlled. Once trace impurities enter the liquid alloy, they can have a destructive effect on the formation of bulk amorphous material, and they can also act directly as nucleation sites to crystallize the alloy. The traditional industrial production casting environment can not meet the casting condition of the bulk amorphous. An environment must be sought that avoids contamination of the liquid alloy during the cast forming process. In addition, the bulk amorphous alloy has the characteristic of high viscosity, and the flow property under the gravity field condition is extremely low. The conventional casting forming method under the gravity field condition is difficult to fill complete components, and the method is impossible for obtaining large-size amorphous castings with complicated structures.

Compared with the prior art, the invention has the following beneficial effects:
1. according to the method, the amorphous alloy liquid is stably filled into the forming die of the filling cabin by utilizing the counter-gravity pouring process, and the complete amorphous alloy component of the complex component can be obtained. In order to ensure the realization of the countergravity pouring method, the space of the cabin sealing structure needs to be filled. The device can isolate the external environment, can be filled with inert gas to form pressure difference with the smelting chamber, and is convenient for realizing the counter-gravity pouring.
2. The utility model provides a go up and down to realize intercommunication function through filling cabin movable plate 5 between contrary gravity filling cabin and the outside smelting cabin. When the filling cabin movable plate 5 is separated from the filling cabin lower door sealing ring 3 of the bottom opening 2 of the countergravity filling cabin, the smelting cabin and the countergravity filling cabin are communicated, and the pressure of the smelting cabin and the pressure of the countergravity filling cabin are equal. When the filling cabin movable plate 5 descends to press the filling cabin lower door sealing ring 3, the melting cabin and the antigravity filling cabin are sealed to form mutually independent spaces, and the functions of different pressures of the melting cabin and the antigravity filling cabin can be realized.
3. The bottom opening 2 of the antigravity filling cabin at the bottom of the cabin body 1 has two functions, namely, a channel between the antigravity filling cabin and an external smelting cabin, and when the antigravity filling cabin is communicated with the smelting cabin, the gas pressure in the two cabins is equal; when the filling cabin movable plate 5 descends to press the filling cabin lower door sealing ring 3, the anti-gravity filling cabin and the smelting cabin are separated into two independent spaces; an anti-gravity filling riser pipe is arranged on the filling cabin movable plate 5, and the top of the cabin body 1 is opened for placing/dismounting the mould and maintaining. The upper cover 13 is pressed on the upper door sealing ring 9 of the filling cabin, and is locked by the upper door locking ring 8 of the filling cabin to realize sealing. The filling chamber observation window 10 is used for observing the internal condition of the chamber body 1. The upper cover lifting oil cylinder 15 and the filling cabin movable plate driving cylinder 11 are used for driving vertical lifting operation.

A filling cabin inert gas input valve 6, a filling cabin exhaust valve 7, a heat exchange medium input disc, a heat exchange medium output disc and a filling cabin electric power input disc are arranged on a cabin wall to ensure that the counter-gravity filling cabin 3 works.
4. When the filling cabin moving plate 5 descends to press the filling cabin lower door sealing ring 3 tightly, the liquid ascending straight pipe descends into the external alloy smelting cold wall crucible. At the moment, the external smelting chamber and the antigravity filling chamber are completely separated, and only the inner hole of the liquid ascending straight pipe on the filling chamber moving plate 5 is communicated with the alloy smelting cold wall crucible and the forming die. At the moment, when the gas pressure in the antigravity filling cabin is lower than the gas pressure in the smelting cabin, pressure difference is formed, and when the pressure difference is large enough, liquid metal in the alloy smelting cold-wall crucible is forced to continuously rise along the inner hole of the liquid-rising straight pipe and enter a mold, so that the molten metal antigravity filling forming is realized, the invasion of harmful elements is avoided, and the purity of the total impurity content of less than 0.5 wt% when the alloy is formed into an amorphous alloy can be ensured.
