[0032] Other objects and advantages of the present invention will become clear by explaining the preferred embodiments of the present application below.

[0033] Example 1

[0034] like Figures 1-6 As shown, a high-performance multi-alloy parts post-processing equipment has a housing 1, which is a hollow tube. The top of the housing 1 is provided with a top cover 2 and the bottom is provided with a bottom cover 3, forming a sealed cavity 101 inside the housing 1.

[0035] like Figure 1 As shown, the heat insulation layer 8 is located within the sealed cavity 101, and the heat insulation layer 8 has a longitudinally arranged working cavity 802. The working cavity 802 is located between the core tube 5 and the heat insulation layer 8. The heat insulation layer 8 can have a tubular structure, but it can also be designed in other shapes, such as a multi-faceted perforated shape.

[0036] like Figures 1-3 As shown, the flow divider 4 is located on the upper side of the heat insulation layer 8, covering the upper opening of the working chamber 802. A fastening part 404 is provided on the lower side of the flow divider 4. This fastening part 404 can be, for example, a groove structure. A boss structure that mates with this groove structure is provided on the top of the heat insulation layer 8, realizing the connection between the flow divider 4 and the heat insulation layer 8. The cooperation between the aforementioned boss structure and the groove structure facilitates the alignment of the flow divider 4 and the heat insulation layer 8.

[0037] like Figures 2-4 As shown, the flow divider 4 is fixedly connected to the upper end of the core tube 5. When the flow divider 4 is lifted, the core tube 5 can be lifted together to place the parts to be processed into the downstream processing equipment, and to remove the parts from the equipment after processing. In some embodiments, the upper end of the core tube 5 and the flow divider 4 are configured to be detachably connected.

[0038] like Figure 3As shown, the core tube 5 has a longitudinally arranged central hole 501. The outer surface of the core tube 5 is provided with multiple longitudinally spaced fixing grooves 502. This embodiment includes multiple longitudinally spaced support plates 6, each support plate 6 having a downward-opening conical hole 601 at its center, used to place parts. An annular retaining ring 7 is located between the support plate 6 and the core tube 5. The outer side of the retaining ring 7 has an outer conical surface 701 with its larger end facing downwards and adapted to the conical hole 601. The interior of the retaining ring 7 has a connecting hole 702 adapted to the fixing grooves 502.

[0039] In some embodiments, the retaining ring 7 is composed of two halves 703, and in other embodiments, the retaining ring 7 is composed of three or more halves 703.

[0040] When installing the support plate 6, first, fit the retaining ring 7 onto the fixing groove 502, with the larger end of the retaining ring 7 on the lower side. Then, fit the tapered hole 601 of the support plate 6 onto the outer tapered surface 701 of the retaining ring 7. The above-mentioned tapered surface mating structure can provide stable support for the support plate 6.

[0041] When adjusting the height of the support plate 6, lift the support plate 6, remove the multiple halves 703 of the retaining ring 7 from the fixing groove 502, and install them into another fixing groove 502 at a suitable height. Then, fit the tapered hole 601 of the support plate 6 with the outer tapered surface 701 of the retaining ring 7, which is convenient and quick.

[0042] In some embodiments, such as Figure 2 As shown, the support plate 6 is provided with a vent 602 that runs through the vertical direction to allow airflow within the working chamber 802.

[0043] In some embodiments, the top of the diversion shroud 4 is provided with a radially outwardly projecting radial protrusion 403; the radial protrusion 403 is provided with a plurality of evenly distributed grooves 409 along the circumferential direction. Matching the above structure, the present invention also provides a lifting component 19, such as... Figure 13 As shown, the bottom of the lifting component 19 has a circular recess 1901, and a plurality of radially inwardly protruding retaining portions 1902 are provided at the opening of the recess 1901. The retaining portions 1902 correspond one-to-one with the groove portions 409.

[0044] When the lifting component 19 is connected to the diversion cover 4, the clamping part 1902 and the groove part 409 are opposite each other. After the two are brought close together, the clamping part 1902 passes through the groove part 409, and then the lifting component 19 is rotated so that the clamping part 1902 and the groove part 409 are offset at a certain angle in the circumferential direction. Thus, the diversion cover 4, as well as the core tube 5, support plate 6 and the parts placed on the support plate 6 connected to its lower side, can be lifted by the lifting component 19.

[0045] The structure in the embodiment can also be applied to other types of part post-processing equipment, such as cold isostatic pressing, warm isostatic pressing equipment, in addition to the heat isostatic pressing equipment.

[0046] Embodiment 2

[0047] In the high-performance multi-element alloy part post-processing equipment, the cooling process plays a crucial role in the material characteristics of the part, and a certain cooling speed needs to be strictly followed to ensure the material quality. In addition, the cooling process also needs to pay attention to uniform cooling of the part, and the internal stress caused by temperature difference may cause the part to warp, crack due to notch stress concentration, etc.

[0048] In Embodiment 1, in order to place and take out the part in the working cavity 802, the shunt cover 4, the core tube 5 and the support sheet 6 are fixedly connected, and lifting the shunt cover 4 can lift and lower the part. Embodiment 2 further designs a cooling gas circulation flow path structure in the high-performance multi-element alloy part post-processing equipment on the basis of Embodiment 1. The suction structure 10 for sucking high-temperature gas from the working cavity 802 is formed between the liftable shunt cover 4 and the fixedly arranged spacing layer 9, so that the high-temperature gas is mixed with the low-temperature gas, and the mixed medium-temperature gas is then contacted with the cooled shell 1 to be cooled to form low-temperature gas, so that the part in the working cavity 802 is cooled according to the set requirements, and the cooling speed is avoided to be too fast or too slow.

[0049] The following will be described in detail.

[0050] As shown in Figure 1 , in some embodiments, the outer side of the shell 1 is surrounded by a cooling pipe manifold 14. In some embodiments, as shown in Figure 14 , the cooling pipe manifold 14 has a shape repeatedly winding along the up-down direction and circumferentially stacking around the shell 1. Since the shell 1 has a certain deformation after being heated, the shape of the above-mentioned cooling pipe manifold 14 is beneficial to adapt to the deformation of the shell 1, and avoids the breakage of the cooling pipe manifold 14 caused by the deformation of the shell 1. The cooling pipe manifold 14 may, for example, be copper. It should be noted that, in order to clearly show, Figure 14 , the number of circumferential stacks of the cooling pipe manifold is intentionally reduced in the drawings, and in actual production, the density of the circumferential stacks of the pipes in the cooling pipe manifold 14 can be designed according to needs.

[0051] As shown in Figure 1As shown in the figure, a wind deflector 16 is arranged at the lower side of the working cavity 802, which can be formed in a cylindrical shape for example. The inner hole of the wind deflector 16 is communicated with the central hole 501 of the core tube 5. A wind deflector hole 1601 is formed through the side wall of the wind deflector 16. An annular cavity 17 is formed between the wind deflector 16 and the heat insulation layer 8. A wind deflector element 15 is arranged in the annular cavity 17, and the outlet of the wind deflector element 15 is opposite to the wind deflector hole 1601, which is used to input the high-speed cooling gas from the outside into the wind deflector hole 1601. The wind deflector element 15 can be a nozzle for example. The wind deflector element 15 can be connected with a gas storage device and a pump outside through a pipeline, and the high-speed cooling gas is provided to the wind deflector element 15 through the pump and the gas storage device.

[0052] In addition, a heating element 13 is arranged at the upper part of the annular cavity 17, which is used to heat the working cavity 802. The heating element 13 is closed when the part is cooled. A partition ring 18 is arranged at the lower side of the heating element 13, which divides the annular cavity 17 into two parts. A certain gap is also left between the partition ring 18 and the heat insulation layer 8, so that the gas can flow upward when the heating element 13 is working.

[0053] As shown in the figures, Figure 1 , Figure 4 and Figure 14 , a middle hole part 401 is arranged in the flow divider 4, and the lower end of the middle hole part 401 is communicated with the central hole 501 of the core tube 5. A radial hole 402 is arranged at the upper part of the flow divider 4, which is extended radially, and one end of the radial hole 402 is communicated with the central hole 501, and the other end is extended radially outward to the outer surface of the flow divider 4. As shown by the solid arrow 20 in the figure, Figure 1 the low-temperature gas enters the inner cavity of the wind deflector 16 from the wind deflector hole 1601, and then flows upward through the central hole 501 into the middle hole part 401, and then flows through the middle hole part 401 into the radial hole 402, and then flows into the top cavity 21 between the flow divider 4 and the spacing layer 9.

[0054] As shown in the figures, Figure 11 , Figure 12 , a suction hole 408 is arranged at the lower side of the radial hole 402 of the flow divider 4; and an outer circular part 407 is arranged at the outer surface of the flow divider 4, which protrudes radially outward, a first outer taper surface 405 is formed at the upper side of the outer circular part 407, and a second outer taper surface 406 is formed at the lower side of the outer circular part 407.

[0055] As shown in the figures, Figure 1 , 7 , a cylindrical spacing layer 9 is arranged between the heat insulation layer 8 and the shell 1. An inner hole part 908 is arranged at the inner hole of the spacing layer 9, which protrudes radially inward, a first inner taper hole 906 is arranged at the upper side of the inner hole part 908, and a second inner taper hole 907 is arranged at the lower side of the inner hole part 908.

[0056] AsFigure 11 and Figure 12 As shown in FIG. 10, the first outer conical surface 405 and the first inner conical hole 906 form an accelerating cavity 1001 with gradually decreasing cross-sectional area from top to bottom; the outer circular part 407 and the inner hole part 908 form a straight flow section 1002; the second outer conical surface 406 and the second inner conical hole 907 form a diffusing cavity 1003 with gradually increasing cross-sectional area from top to bottom. The accelerating cavity 1001, the straight flow section 1002 and the diffusing cavity 1003 form the suction structure 10. As shown in FIG. 11, the suction hole 408 is in communication with the working cavity 802 at one end and with the straight flow section 1002 at the other end, and the suction structure 10 sucks the high-temperature gas in the working cavity 802 through the suction hole 408. Figure 12

[0057] As shown in FIG. 12, the spacer layer 9 has an inner side wall 901 on the inner side in the radial direction and an outer side wall 902 on the outer side in the radial direction, forming a spacer cavity 903 between the inner side wall 901 and the outer side wall 902; the inner side wall 901 and the heat insulation layer 8 form a mixing cavity 11; the outer side wall 902 and the inner surface of the outer wall of the shell 1 form a cooling cavity 12; the lower end of the inner side wall 901 is provided with a gas flow inlet 904 for communication between the mixing cavity 11 and the spacer cavity 903; the upper end of the outer side wall 902 is provided with a gas flow outlet 905 for communication between the spacer cavity 903 and the cooling cavity 12. Figure 1 7

[0058] During the flow of the low-temperature gas from the top cavity 21 to the accelerating cavity 1001, the flow rate of the low-temperature gas increases due to the gradually decreasing cross-sectional area of the accelerating cavity 1001 from top to bottom, and a negative pressure is formed in the straight flow section 1002. As shown in FIG. 13, under the action of the negative pressure, the high-temperature gas in the working cavity 802 flows to the straight flow section 1002 through the suction hole 408 in the direction indicated by the dashed arrow 22. The low-temperature gas and the high-temperature gas mix to form a medium-temperature gas in the diffusing cavity 1003 and the mixing cavity 11 below the diffusing cavity 1003, and the medium-temperature gas sequentially enters the spacer cavity 903 through the gas flow inlet 904 and then flows to the cooling cavity 12 through the top gas flow outlet 905, and is cooled in the cooling cavity 12 before entering the annular cavity 17 through the gap part 801, forming a circulation of the gas flow.
