step S2: after the vacuum door 101 of the vacuum chamber 1 is closed and sealed, the vacuum chamber 1 is evacuated. The plurality of pressure rods 301 descend and the bottoms of the pressure rods are pressed downwards from the upper parts of the grooves 304 to provide static pressure for the metal mixed powder in the grooves 304, and meanwhile, the pressure rods 301, the hot static pressure die 302 and the jacking rod 303 heat the metal mixed powder, so that the metal mixed powder is prepared to form a high-temperature alloy block 4;
step S3: lifting and resetting the pressure lever 301, and lifting the lifting lever 303 to lift the superalloy block 4;
step S4: the vacuum manipulator 2 places M rows by N columns of high-temperature alloy blocks 4 on corresponding M rows by N columns of heat preservation stacks one by one;
step S5: the vacuum manipulator 2 places heat insulation sleeves 7 one by one on each high-temperature alloy block 4;
step S6: under each superalloy block 4, the amount of heat transferred from each superalloy block 4 to the cold plate 5 is different due to the different number of insulation blocks 6 in the insulation stack, i.e. the heat treatment process of each superalloy block 4 is different;
step S7: finally obtaining M rows by N columns of high-temperature alloy blocks 4 with different heat treatment processes, wherein the grain sizes of each high-temperature alloy block 4 are different.
In the embodiment of the invention, the vacuum manipulator 2 is preferably a four-degree-of-freedom vacuum manipulator, and one of the vacuum manipulators clamps the side surface of the superalloy block 4 or the heat insulation sleeve 7; secondly, horizontally advancing and retreating; thirdly, horizontally moving leftwards and rightwards; fourth, the height direction rises and falls.
In the embodiment of the present invention, the metal mixed powder is in different grooves 304 of the hot hydrostatic die 302, and the total mass and volume are equal, but the metal elements are different. For example, each superalloy block 4 contains 12 elements of titanium, aluminum, magnesium, nickel, and the like. But each element has a different ratio. For example, one groove 304 contains 2.37% of nickel and the other groove 304 contains 4.61% of nickel, so that M rows by N columns of superalloy blocks 4 are prepared, and the material properties of each superalloy block 4 are different.
In the embodiment of the invention, the number of the heat preservation blocks 6 in each heat preservation stack is different by M rows and N columns, the heat resistance of the heat preservation blocks 6 is larger than that of the high-temperature alloy block 4, and the heat preservation blocks 6 can cover the lower surface of the high-temperature alloy block 4. The high-temperature alloy block 4 only contains a heat conduction cooling mode, and the vacuum environment of the vacuum chamber 1 cuts off a heat convection heat dissipation mode of the high-temperature alloy block 4. The heat insulation sleeve 7 can cover the upper surface and the side surface of the high-temperature alloy block 4, effectively blocks the heat radiation and the heat dissipation of the high-temperature alloy block 4, and the heat resistance of the heat insulation sleeve 7 is larger than that of the heat insulation block 6. The cold plate 5 can quickly transfer heat to the outside of the vacuum chamber 1 and maintain constant temperature, and concretely, the conventional engineering implementation consists of a liquid storage tank, a cooling liquid pump, a cooling pipe, a vacuum through-wall sealing plug, a temperature sensor, a radiator and the like, and the principle is an industrial air conditioner.
According to the invention, the high-temperature alloy block 4 is shielded through the heat insulation sleeve 7 in a vacuum environment, no heat radiation and no heat convection are generated, and the heat insulation block 6 and the cold plate 5 effectively enable the high-temperature alloy block 4 to have heat conduction, so that the heat treatment process of the high-temperature alloy block 4 is more accurate. A series of process actions are completed in the vacuum environment in the vacuum chamber 1 through the vacuum manipulator 2, so that the automation degree is high, and the manual error rate is reduced.
According to the high-flux preparation device for the high-temperature alloy blocks, M rows and N columns of high-temperature alloy blocks are obtained in one process cycle, the heat treatment process of each high-temperature alloy block is different, the high-flux preparation device accords with the high flux of genetic material engineering, and each heat treatment completed in one process flow has the difference, so that the high-flux preparation of the high-temperature alloy blocks is realized.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
