Technical Field
[0001] This invention relates to the field of isostatic press technology, and in particular to an isostatic press and its supporting structure. Background Technology
[0002] An isostatic press typically consists of a booster, a high-pressure chamber, and a support structure to support the high-pressure chamber. Currently, the booster is usually connected to the high-pressure chamber via high-pressure pipelines. However, the lifespan of these high-pressure pipelines is significantly shortened after operating under pressures of 70 MPa and above, thus affecting the reliability of the isostatic press. Furthermore, frequent replacement of the high-pressure pipelines increases costs. Summary of the Invention
[0003] In order to solve the above problems, the present invention proposes an isostatic press and its supporting structure.
[0004] In a first aspect, the isostatic press of the present invention has a support structure comprising at least one set of support frames, each support frame including two crossbeams and a plurality of columns. The two crossbeams are spaced apart in a first direction, and the plurality of columns are disposed between the two crossbeams and together with the two crossbeams form an installation space, wherein the first direction intersects the thickness direction of the crossbeams. At least one of the two crossbeams has a flow channel internally, and the flow channel communicates with the installation space.
[0005] Furthermore, the crossbeam has: a first side surface; a second side surface connected to both ends of the first side surface; and two end faces, the two end faces being disposed opposite each other in a second direction, the end faces being connected to the first side surface and the second side surface, the second direction being parallel to the thickness direction of the crossbeam.
[0006] Furthermore, the flow channel includes a first flow channel segment and a second flow channel segment that are interconnected, the second flow channel segment intersects with the first flow channel segment, and at least one of the flow channel openings of the first flow channel segment and the second flow channel segment is located on the second side.
[0007] Furthermore, the second flow channel segment extends along the first direction, and one end of the second flow channel segment is connected to the first flow channel segment, while the other end is located on the second side. The first and second flow channel segments form a T-shaped structure, and the first flow channel segment communicates with the installation space via the second flow channel segment.
[0008] Furthermore, the extension direction of the first flow channel segment is parallel to the second direction, and the two end outlets of the first flow channel segment are respectively located on a corresponding end face.
[0009] Furthermore, the extension direction of the first flow channel segment is parallel to the third direction, and the flow channel openings at both ends of the first flow channel segment are located on the first side surface, wherein the third direction intersects with the second direction and the first direction.
[0010] Furthermore, the first flow channel segment and the second flow channel segment form a V-shaped structure, and one of the flow channel openings of the first flow channel segment and the second flow channel segment are located on the second side and have overlapping portions; the other flow channel opening of the first flow channel segment and the second flow channel segment are located on the first side.
[0011] Furthermore, the flow channel includes a third flow channel segment, a fourth flow channel segment, and a fifth flow channel segment. The third flow channel segment and the fourth flow channel segment form a V-shaped structure, and one of the flow channel openings of the third flow channel segment and the fourth flow channel segment has an overlapping portion. The other flow channel openings of the third flow channel segment and the fourth flow channel segment are both located on the first side. The fifth flow channel segment extends along the first direction, and one end of the fifth flow channel segment is connected to the third flow channel segment and the fourth flow channel segment, while the other end of the fifth flow channel segment is located on the second side.
[0012] Furthermore, the crossbeam is an integral structure, and the column abuts between the two crossbeams and is connected to the two crossbeams to form a frame structure.
[0013] Furthermore, the crossbeam includes a load-bearing beam and a pad, and at least one of the load-bearing beam and the pad has the flow channel inside; the column abuts between the two load-bearing beams and is connected to the two load-bearing beams to form a frame structure, and the pad is located in the space enclosed by the load-bearing beam and the column.
[0014] Furthermore, the surface of the supporting beam facing the column is a plane, the supporting beam and the two columns enclose the installation space, and the pad is located within the installation space.
[0015] Furthermore, the supporting beam provides a receiving space for accommodating the pad, and the pad and the two columns form the installation space. Each supporting beam includes multiple halves, which are joined together to form the receiving space, with the halves at both ends abutting against their respective columns.
[0016] In a second aspect, the isostatic press of the present invention includes a booster, a high-pressure chamber, and a support structure for the isostatic press as described above. The high-pressure chamber is disposed within the installation space and communicates with the flow channel; the booster is communicated with the flow channel to pressurize the high-pressure chamber through the flow channel.
[0017] The present invention has the following beneficial effects: Because the crossbeam supporting the frame has internal flow channels, the booster can connect to the high-pressure chamber through these channels. The high-pressure medium from the booster can then be directly pumped into the high-pressure chamber via these channels, pressurizing it to 600 MPa or higher. Therefore, this application, by using the flow channel T inside the crossbeam, can completely replace external high-pressure pipelines, thereby improving the reliability of the isostatic press in high-pressure environments. Furthermore, since this application eliminates the need for external high-pressure pipelines, it avoids the cost associated with frequent pipeline replacements, thus contributing to a reduction in the cost of the isostatic press.

The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment".

[0024] This application provides an isostatic press, which can be a warm isostatic press, a cold isostatic press, or a hot isostatic press. The embodiments of this application are not limited to this.
[0025] Please refer to Figures 1 to 8 The static pressure unit 000 includes a load-bearing structure 100, a high-pressure chamber 200, and a booster 300.
[0026] Among them, the bearing structure 100 serves as the bearing mechanism of the isostatic press 000 and can support the high-pressure chamber 200. The high-pressure chamber 200 can be filled with pressure-transmitting media (such as oil / water / gas). The booster 300 serves as a power source and can pump the high-pressure pressure-transmitting media into the high-pressure chamber 200 to pressurize the high-pressure chamber 200.
[0027] The load-bearing structure 100 may include at least one set of load-bearing frames. Specifically, such as... Figure 1 and Figure 2 As shown, the load-bearing frame may include a set of load-bearing frames; as Figure 3 and Figure 4 As shown, the load-bearing frame may include two sets of load-bearing frames. Of course, it is not limited to this; the load-bearing frame may also include two or more sets of load-bearing frames. When the load-bearing frame includes two or more sets of load-bearing frames, adjacent sets of load-bearing frames are connected to each other (e.g., by bolts).
[0028] like Figure 2 , Figure 4 as well as Figures 6 to 8 As shown, each set of support frames in the support structure 100 may include two crossbeams 10 and multiple columns 20. The two crossbeams 10 are spaced apart in a first direction L1, which intersects the thickness direction of the crossbeams 10. For example, the first direction L1 is perpendicular to the thickness direction of the crossbeams 10.
[0029] Multiple columns 20 are positioned between two crossbeams 10, forming an installation space R together with the two crossbeams 10. At least one of the two crossbeams 10 has an internal flow channel T, which communicates with the installation space R. A high-pressure chamber 200 is positioned within the installation space R, and a pressure booster 300 communicates with the flow channel T to pressurize the high-pressure chamber 200. Specifically, the pressure booster 300 can communicate with the flow channel T via a plug 400.
[0030] It should be noted that, to ensure sufficient strength of the load-bearing frame, the crossbeam 10 is typically made of ultra-high strength forged steel with a tensile strength ≥1000MPa. The wall thickness of the flow channel T can be calculated and designed using the Lamié formula and verified through finite element analysis to ensure that the stress state of the flow channel wall of flow channel T is within the yield strength, while reserving a certain safety margin to improve the stability of the flow channel wall of flow channel T under high pressure.
[0031] In this application, since the crossbeam 10 supporting the frame has a flow channel T inside, the booster 300 can communicate with the high-pressure chamber 200 through the flow channel T inside the crossbeam 10. Therefore, the high-pressure transmission medium from the booster 300 can be directly pumped into the high-pressure chamber 200 through the flow channel T to pressurize the high-pressure chamber 200, increasing the pressure inside the high-pressure chamber 200 to 600 MPa or higher. Thus, by using the flow channel T inside the crossbeam 10, this application can completely replace external high-pressure pipelines, thereby improving the reliability of the isostatic press 000 in high-pressure environments (especially high-pressure environments of 600 MPa and above). Furthermore, since this application does not require external high-pressure pipelines, it avoids the cost problems caused by frequent replacement of high-pressure pipelines, thereby helping to reduce the cost of the isostatic press 000.
[0032] In some embodiments, such as Figure 2 As shown, the crossbeam 10 of the isostatic press 000 can be an integral structure, and the column 20 abuts between the two crossbeams 10 and is connected to the two crossbeams 10 to form a frame structure. The crossbeam 10 can be a semi-circular beam, an elliptical beam, a rectangular beam, or an arched beam. The specific shape of the crossbeam 10 is not limited in this embodiment.
[0033] Specifically, the outer edge of the column 20 in the third direction L3 does not extend beyond the crossbeam 10, and both ends of the column 20 directly abut against the two opposing crossbeams 10. The column 20 and the crossbeams 10 at both ends can be fixed together by winding steel wire, forming a load-bearing frame structure.
[0034] In some embodiments, such as Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the crossbeam 10 of the supporting frame may include a supporting beam 10A and a pad 10B, with at least one of the supporting beam 10A and the pad 10B having a flow channel T inside. The column 20 abuts between the two supporting beams 10A and is connected to the two supporting beams 10A to form a frame structure, while the pad 10B is located within the space enclosed by the supporting beams 10A and the column 20. A third direction L3 intersects with the second direction L2 and the first direction L1. Specifically, the supporting beam 10A can be a semi-circular beam (e.g., ...). Figure 4 As shown), elliptical beams, rectangular beams (such as...) Figure 6 and Figure 7 (as shown) or arched beams (such as) Figure 8 As shown in the figure, the specific shape of the load-bearing beam 10A is not limited in this embodiment.
[0035] In some embodiments, such as Figure 4 , Figure 6 and Figure 7As shown, the surface of the supporting beam 10A facing the column 20 is flat. The supporting beam 10A and the two columns 20 enclose an installation space R, and the pad 10B is located within the installation space R. Specifically, the column 20 can be separately installed from the supporting beam 10A (e.g., Figure 4 and Figure 6 As shown), it can also be set up as a whole (such as...). Figure 7 (As shown), this application does not limit this.
[0036] like Figure 8 As shown, the supporting beam 10A itself can enclose a receiving space for the receiving pad 10B, and the pad 10B is received in the receiving space and together with the two columns 20, they form an installation space R.
[0037] Each load-bearing beam 10A may include multiple halves 31, which are spliced together to form a receiving space, with the halves 31 at both ends abutting against the corresponding columns 20. That is, in this embodiment, the load-bearing beam 10A is adapted to the pad 10B, and the columns 20 and the load-bearing beams 10A and pads 10B at both ends can be fixedly connected together by winding steel wire to form a load-bearing frame in the form of a frame structure.
[0038] It should be noted that the crossbeam 10 can have any of the above-mentioned structural forms. Regardless of the structural form adopted, the crossbeam 10 can include the following: Figures 9 to 12 Any of the structures shown. That is, when the crossbeam 10 is a single-piece structure, Figures 9 to 12 The structure shown is the crossbeam 10; when the crossbeam 10 includes the load-bearing beam 10A and the pad block 10B, Figures 9 to 12 The structure shown can be the load-bearing beam 10A and / or the pad 10B. Additionally, Figures 9 to 12 The structures shown are all illustrated using a semi-circle as an example, but it is not intended to limit them to only semi-circular structures.
[0039] Please refer to Figures 9 to 12 The crossbeam 10 has a first side surface 11, a second side surface 12, and two end faces 13. The first side surface 11 is connected to the second side surface 12 at both ends in its bending direction, and the two end faces 13 are arranged opposite each other in a second direction L2, and the end faces 13 are connected to the first side surface 11 and the second side surface 12. The second direction L2 is parallel to the thickness direction of the crossbeam 10. For example, when the crossbeam 10 is a semi-circular beam, the first side surface 11 is an arc-shaped surface, the second side surface 12 is a rectangular surface and is connected to both ends of the first side surface 11, and the end faces 13 are semi-circular surfaces.
[0040] In some embodiments, such as Figures 9 to 12As shown, the flow channel T may include a first flow channel segment T1 and a second flow channel segment T2 that are interconnected. The second flow channel segment T2 is intersecting with the first flow channel segment T1 (i.e., the second flow channel segment T2 is set at a certain angle to the first flow channel segment T1), and at least one of the flow channel openings of the first flow channel segment T1 and the second flow channel segment T2 is located on the second side surface 12.
[0041] Specifically, the angle between the second flow channel section T2 and the first flow channel section T1 can be 90°, greater than 0° and less than 90°, or greater than 90° and less than 180°. This application does not impose any limitations on the embodiments described.
[0042] In this embodiment, only one of the flow channels of the first flow channel segment T1 may be located on the second side surface 12, or only one of the flow channels of the second flow channel segment T2 may be located on the second side surface 12, or both one of the flow channels of the first flow channel segment T1 and one of the flow channels of the second flow channel segment T2 may be located on the second side surface 12.
[0043] Furthermore, the first flow channel section T1 and the second flow channel section T2 can respectively send high-pressure transmission medium into the high-pressure chamber 200 through the corresponding booster 300; alternatively, one of the first flow channel section T1 and the second flow channel section T2 can send high-pressure transmission medium into the high-pressure chamber 200 through the other, and this application embodiment does not limit this.
[0044] In some embodiments, such as Figure 9 and Figure 10 As shown, the second flow channel segment T2 extends along the first direction L1, and one end of the flow channel segment T2 is connected to the first flow channel segment T1, while the other end is located on the second side surface 12. The first flow channel segment T1 and the second flow channel segment T2 form a T-shaped structure (i.e., the first flow channel segment T1 and the second flow channel segment T2 are arranged perpendicularly to each other), and the first flow channel segment T1 is connected to the installation space R via the second flow channel segment T2.
[0045] In this embodiment, since one end of the flow channel T2 is connected to the first flow channel T1 and the other end is located on the second side 12, the flow channel T is connected to the high-pressure chamber 200 located in the installation space R through the second flow channel T2, so the booster 300 can sequentially send high-pressure transmission medium into the high-pressure chamber 200 through the first flow channel T1 and the second flow channel T2.
[0046] In some embodiments, such as Figure 9 As shown, the extension direction of the first flow channel segment T1 is parallel to the third direction L3, and the flow channel openings at both ends of the first flow channel segment T1 are located on the first side surface 11. The third direction L3 intersects the second direction L2 and the first direction L1; for example, the third direction L3 is perpendicular to the second direction L2 and the first direction L1.
[0047] It should be noted that, in this embodiment, based on the different positions of the two end outlets of the first flow channel segment T1 on the first side surface 11, the line connecting any outlet of the first flow channel segment T1 on the first side surface 11 and the outlet of the second flow channel segment T2 on the second side surface 12 forms an angle of different sizes with the second side surface 12 (e.g., 25°~75°). For example, the angle formed by the line connecting any outlet of the first flow channel segment T1 on the first side surface 11 and the outlet of the second flow channel segment T2 on the second side surface 12 with the second side surface 12 can be 25°, 30°, 45°, 60°, 70°, 75°, etc.
[0048] Therefore, in this embodiment, since the flow channel openings at both ends of the first flow channel segment T1 are distributed on the first side surface 11, different structural forms of flow channels T can be obtained by adjusting the position of the flow channel openings on the first side surface 11.
[0049] In other embodiments, such as Figure 10 As shown, the extension direction of the first flow channel section T1 is parallel to the second direction L2, and the two end outlets of the first flow channel section T1 are respectively located on a corresponding end face 13. That is, the first flow channel section T1 is arranged to penetrate the crossbeam 10 along the thickness direction of the crossbeam 10.
[0050] In some embodiments, such as Figure 11 As shown, the first flow channel section T1 and the second flow channel section T2 form a V-shaped structure. One of the flow channel openings of the first flow channel section T1 and one of the flow channel openings of the second flow channel section T2 are both located on the second side surface 12, and they have overlapping portions. The other flow channel opening of the first flow channel section T1 and the other flow channel opening of the second flow channel section T2 are both located on the first side surface 11.
[0051] In this embodiment, since the first flow channel section T1 and the second flow channel section T2 form a V-shaped structure and their flow channel openings on the second side 12 overlap, the first flow channel section T1 and the second flow channel section T2 can be fed into the high-pressure chamber 200 through the overlapping part of their flow channel openings on the second side 12 by the corresponding booster 300.
[0052] It should be noted that, in this embodiment, based on the different positions of the flow channel openings of the first flow channel segment T1 and the second flow channel segment T2 on the first side surface 11, different angles (such as 25°~75°) are formed between the first flow channel segment T1 and the second flow channel segment T2. For example, the angle formed between the first flow channel segment T1 and the second flow channel segment T2 can be 25°, 30°, 45°, 60°, 70°, 75°, etc.
[0053] Therefore, in this embodiment, since one of the flow channel openings of the first flow channel segment T1 and one of the flow channel openings of the second flow channel segment T2 are both distributed on the first side surface 11, flow channels T with different structural forms can be obtained by adjusting the positions of the flow channel openings of the two on the first side surface 11.
[0054] In some embodiments, such as Figure 12 As shown, flow channel T may include a third flow channel segment T3, a fourth flow channel segment T4, and a fifth flow channel segment T5.
[0055] The third flow channel segment T3 and the fourth flow channel segment T4 form a V-shaped structure, with one flow channel opening of the third flow channel segment T3 and one flow channel opening of the fourth flow channel segment T4 overlapping each other. The other flow channel openings of the third flow channel segment T3 and the fourth flow channel segment T4 are both located on the first side surface 11. The fifth flow channel segment T5 extends along the first direction L1. One end of the fifth flow channel segment T5 is connected and communicates with the third flow channel segment T3 and the fourth flow channel segment T4 (i.e., it communicates with the overlapping flow channel openings of the third flow channel segment T3 and the fourth flow channel segment T4), and the other end of the flow channel opening is located on the second side surface 12. That is, the fifth flow channel segment T5, together with the third flow channel segment T3 and the fourth flow channel segment T4, forms a Y-shaped structure.
[0056] It should be noted that, in this embodiment, based on the different positions of the flow channel openings of the third flow channel segment T3 and the fourth flow channel segment T4 on the first side surface 11 and / or the length of the fifth flow channel segment T5, different angles (e.g., 25°~75°) can be formed between the third flow channel segment T3 and the fourth flow channel segment T4. For example, the angle formed between the third flow channel segment T3 and the fourth flow channel segment T4 can be 25°, 30°, 45°, 60°, 70°, 75°, etc.
[0057] Therefore, in this embodiment, since one of the flow outlets of the third flow channel section T3 and one of the flow outlets of the fourth flow channel section T4 are both distributed on the first side surface 11, flow channels T with different structural forms can be obtained by adjusting the position of their flow outlets on the first side surface 11 and / or the length of the fifth flow channel section T5.
[0058] In some embodiments, the inner wall thickness of the flow channel T may be not less than 36 mm. The inner wall thickness of the flow channel T can be calculated using the LaMei formula.
[0059] It should be noted that, in the above embodiments, the radius of curvature of each part of the flow channel T at the connection position can be no less than 3 times the diameter of the flow channel T, thereby avoiding right-angle bends in the flow channel T. Furthermore, the cross-section of the flow channel T adopts a gradual transition without any abrupt changes (such as steps or constrictions). The connection between the flow channel T and the joint or valve must be made of integral forging or a seamless structure.
[0060] Furthermore, the roughness of the inner wall of flow channel T is less than or equal to 0.8 μm, which reduces local turbulence and wear. In addition, flow channel T undergoes high-pressure jet cleaning and ultrasonic testing after machining to ensure the absence of metal debris, burrs, and other impurities, effectively preventing impurities from scratching the inner wall under high pressure and causing leaks.
[0061] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
