The side wall of the top hammer is provided with an assembly step, and the connecting ring and the movable end can clamp the assembly step together.
[0008] As a further improvement to the above technical solution, the six-sided top hydraulic device also includes a heating device, which includes a heating element disposed in the receiving cavity. The heating element has an energized part at its upper and lower ends. The top hammers corresponding to the upper top seat and the lower base are electrically connected to a power supply device via cables. When the top hammers corresponding to the upper top seat and the lower base simultaneously press the composite block, the top hammers can be electrically connected to the energized part, thereby driving the heating element to heat the sample.
[0009] As a further improvement to the above technical solution, the heating element is made of graphite.
[0010] As a further improvement to the above technical solution, the heating element is a rectangular shell, which is sleeved on the outside of the sample.

[0018] During operation, the operator first places the sample to be processed into the receiving cavity of the composite block, and then places the composite block on the top hammer of the first hydraulic device mounted on the lower base. Subsequently, the control module can activate the first hydraulic devices mounted on the front, rear, left, and right side beams, as well as the second hydraulic devices on the upper and lower bases. These hydraulic devices work together to form a powerful driving force, propelling the top hammers in six directions toward the material to be processed. During the pressurizing motion of the top hammers, they apply uniform pressure to the composite block, causing it to deform under the pressure and thus processing the sample. This method of simultaneous and uniform pressure in six directions effectively avoids the problem of internal stress concentration caused by uneven force on the material, thereby ensuring processing quality and material integrity.

[0032] Combination Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a six-sided hydraulic top device, including an upper top seat 100, a lower base 200, a top hammer assembly 600, a control module, a composite block 900, and four side beams 400 for the front, rear, left, and right sides.
[0033] The bottom of the upper top seat 100 and the top of the lower base 200 are respectively equipped with a first hydraulic device 300; the two ends of the side beam 400 are respectively assembled and connected to the side connecting seats 120 of the upper top seat 100 and the lower base 200 by super bolts 110; a second hydraulic device 500 is respectively provided on the inner side of each side beam 400; the top hammer assembly 600 includes a top hammer 610, which is correspondingly disposed on the movable ends 510 of the first hydraulic device 300 and the second hydraulic device 500; the control module is respectively connected to each of the first hydraulic device 300 and the second hydraulic device 500. The hydraulic device 500 is connected for control. The control module uses a PLC, industrial control computer, or microcontroller as the core controller, responsible for signal processing and command output, and a storage unit to store programs, parameters, and data. An operation panel and various sensors form input devices to enable manual command input and equipment status monitoring. Drivers drive the hydraulic device's actuators, and indicator lights and alarms display status and alarms. Internal and external communication interfaces facilitate internal data exchange and connection to external devices such as host computers. A power module provides stable power to all components and offers protection functions. The synthetic block 900 is placed on the top hammer 610 of the first hydraulic device 300 on the lower base 200. The synthetic block 900 has a receiving cavity 910 for accommodating the sample 920 to be processed. Specifically, the synthetic block 900 is a disposable item. During production and processing, the sample 920 can be placed in the receiving cavity 910 to ensure that the synthetic block 900 tightly surrounds the sample 920. The synthetic block 900 is made of black pyrophyllite, semi-sintered halogen oxide, and a composite structure of two or three materials. The control module can drive the corresponding first hydraulic device 300 and second hydraulic device 500 to extend their movable ends 510 toward the synthetic block 900, thereby generating top pressure of different magnitudes from six directions to compress the sample 920.
[0034] In this embodiment, the six-sided hydraulic press provides a six-sided pressure system. During operation, the operator first places the sample 920 to be processed into the receiving cavity 910 of the composite block 900, and then places the composite block 900 onto the top hammers 610 of the first hydraulic device 300 mounted on the lower base 200. Subsequently, the control module can activate the first hydraulic devices 300 mounted on the front, rear, left, and right side beams 400, as well as the second hydraulic devices 500 on the upper top seat 100 and the lower base 200. These hydraulic devices work together to generate a powerful driving force, propelling the top hammers 610 in six directions toward the material to be processed. During the movement of the top hammers 610, they apply uniform pressure to the composite block 900, causing it to deform and thus press the sample 920. This method of simultaneous and uniform pressure application in six directions effectively avoids internal stress concentration caused by uneven force on the material, thereby ensuring processing quality and material integrity. During the high-pressure neutron characterization experiment of the new material sample 920 using this embodiment, the control module can control the top pressure provided by each of the first hydraulic device 300 and the second hydraulic device 500 respectively, so as to adjust the top pressure of the top hammer 610 on the sample 920 in a non-uniform manner, simulate the situation of the sample 920 under complex stress scenarios such as non-uniform stress fields, obtain the characterization parameters of the sample 920 under complex stress scenarios, and obtain more accurate experimental results.
[0035] In some specific embodiments, the top hammer 610 is fitted with a connecting ring 620, which is fixedly connected to the movable end 510 by bolts. The side wall of the top hammer 610 is provided with an assembly step 611, and the connecting ring 620 and the movable end 510 can jointly clamp the assembly step 611 to ensure that the top hammer 610 and the movable end 510 have a stable and reliable connection.
[0036] like Figure 3As shown, in some specific embodiments, the six-sided hydraulic device further includes a heating device 700, which includes a heating element 710 disposed within the receiving cavity 910. The upper and lower ends of the heating element 710 are respectively provided with energized portions 730. The top hammers 610 corresponding to the upper top seat 100 and the lower base 200 are electrically connected to a power supply device via cables 720, which are fixedly connected to the connecting ring 620. The heating element primarily functions to: generate a high-temperature environment for the sample 920, achieving a stable high-temperature environment of 1000–2000℃ within the high-pressure chamber; or trigger phase transitions (e.g., quartz → coesite), chemical reactions (e.g., diamond synthesis), or studies of molten behavior of materials under high pressure (e.g., magma simulation); or compensate for the temperature gradient caused by high pressure, maintaining the isothermal state of the sample 920 region. When the top hammers 610 corresponding to the upper top seat 100 and the lower base 200 simultaneously press down on the composite block 900, the top hammers 610 can be electrically connected to the energized part 730. By energizing the cable 720, the heating element 710 is driven to heat the sample 920. This simultaneous heating of the sample 920 during the pressing synthesis process using the heating device 700 plays a crucial role in the synthesis and sintering of superhard materials. By applying different pressures and temperatures, the grain size of the material can be controlled, thereby synthesizing or sintering materials that meet performance requirements. Furthermore, in superhard material performance testing, operators can easily create different temperature conditions by flexibly adjusting the output power of the heating device 700. Testing the material under these different temperature environments allows for a comprehensive and in-depth understanding of its mechanical properties at various temperatures, such as strength and toughness; physical properties, such as coefficient of thermal expansion and electrical conductivity; and chemical properties, such as oxidation resistance and corrosion resistance.
[0037] In some specific embodiments, the upper and lower ends of the heating element 710 are respectively provided with conductive posts 731. The end of the conductive post 731 facing away from the heating element 710 is abutted against by a conductive plate 732. The end face of the conductive plate 732 facing away from the conductive post 731 is provided with a conductive tube 733. The conductive tube 733 extends out from the side wall of the composite block 900. The conductive post 731, conductive plate 732, and conductive tube 733 cooperate to form a current-carrying part 730. This design facilitates that when the top hammer 610 corresponding to the upper top seat 100 and the lower base 200 presses against the composite block 900, it will first come into contact with the conductive tube 733, thereby forming a reliable conductive path with the heating element 710. As the top hammer 610 presses against the composite block 900 and deforms it, the connection between the top hammer 610 and the conductive tube 733 will become tighter, thereby ensuring stable heating of the sample 920 by the heating element 710.
[0038] In some specific embodiments, the heating element 710 is made of graphite and is specifically tubular. The reason for choosing a graphite tube as the heating element 710 is because it possesses a series of outstanding advantages. From a thermal conductivity perspective, graphite has extremely high thermal conductivity, enabling it to efficiently convert electrical energy into heat energy in a short time and rapidly and evenly transfer it to all parts of the top hammer 610. This rapid and uniform heating method not only significantly shortens the heating time and improves the overall working efficiency of the equipment, but also ensures that the top hammer 610 is heated evenly, avoiding material property differences and equipment damage caused by localized overheating or undercooling.
[0039] Graphite tubes exhibit superior chemical stability. They resist the erosion of various chemicals at high temperatures and are not prone to oxidation, corrosion, or other chemical reactions. This allows graphite tubes to maintain structural and performance stability during use, reducing the frequency of damage to and replacement of the heating element 710 due to chemical corrosion, and lowering equipment maintenance costs.
[0040] Of course, it should be noted that in other embodiments covered by this utility model, the material selection of the heating element 710 is not fixed, but can be flexibly adjusted according to the different characteristics of the actual processed materials. Specifically, in addition to the currently used material, the heating element 710 can also be made of a material with specific properties, such as lanthanum chromate, or a metallic material, including but not limited to pure metals such as rhenium, tantalum, and platinum, or alloys formed by combining these metals. However, due to the variety and complexity of the specific situations involved, the details of using these materials for the heating element 710 will not be elaborated here.
[0041] In some specific embodiments, the heating element 710 is a rectangular shell, which is sleeved on the outside of the sample 920 to facilitate a uniform heating effect on the sample 920 when the heating element 710 is heating. Of course, in other embodiments of this utility model, the heating element 710 can also be set to a cylindrical shape according to the different shapes of the sample 920 being processed, in order to ensure the processing effect on the sample 920.
[0042] In some specific embodiments, the space between the heating element 710 and the inner wall of the receiving cavity 910 is filled with a filler of the same material as the synthesized block 900; the space between the heating element 710 and the sample 920 is filled with a pressure-stabilizing filler, specifically a hexagonal boron nitride column or a sodium chloride column; the hexagonal boron nitride column has good chemical stability, thermal stability and insulation, and can maintain stable performance under high temperature and high pressure conditions; the sodium chloride column has a regular crystal structure and can transmit pressure well when subjected to force.
[0043] The purpose of this design is that when the composite block 900 deforms under top pressure from six directions, the filler material between the heating element 710 and the inner wall of the receiving cavity 910, as well as the pressure-stabilizing filler material between the heating element 710 and the sample 920, can work together. They can evenly transmit the top pressure from each direction to the sample 920 within the heating element 710, effectively preventing stress concentration in the sample 920 due to uneven force distribution, thereby improving the processing quality and stability of the sample 920.
[0044] Of course, in other embodiments of this utility model, the filler material between the heating element 710 (710) and the inner wall of the receiving cavity 910 (910) can also be selected according to the selected sample 920 or the required processing environment. The filler material can be different from or similar to the material of the synthetic block 900. The selection of the filler material needs to be considered from multiple aspects such as its pressure flowability, coefficient of thermal expansion and neutron transmittance, as specifically analyzed below:
[0045] Pressure Transmissibility: For efficient pressure transfer to the sample, the fluidity ranking is: pyrophyllite > Cr2O3 > MgO > ZrO2. For high-pressure scenarios (>10 GPa), Cr2O3-pyrophyllite is preferred.
[0046] Coefficient of thermal expansion (CTE, 10) -6 / K): Thermal-mechanical coupling design: Insulation layer CTE ≈ Pressure transmission medium CTE × 0.9–1.1 (e.g., pyrophyllite pressure transmission medium with Cr2O3 insulation layer).
[0047] Neutron transmittance (@λ = 1.8 Å) path optimization principle: Neutron beam path: MgO > ZrO2 > Cr2O3 > pyrophyllite. Intensity can be sacrificed for transmittance in non-detection areas (e.g., pyrophyllite for lateral applications). In some specific embodiments, the side beam 400 consists of multiple parallel elongated plates 410. The upper and lower ends of each elongated plate 410 are respectively assembled and connected to the side connecting seats 120 of the upper top seat 100 and the lower base 200. By decomposing the side beam 400 into multiple elongated plates 410, the pressure it receives can be distributed, reducing the probability of damage and improving the reliability of this embodiment.
[0048] In some specific embodiments, the side beam 400 is arc-shaped, deviating from the telescopic axis of the first hydraulic device 300, to further improve the overall tensile strength of the side beam 400. The side beam 400 has a vertically arranged mounting section 420 in its middle, and a mounting frame 800 is fixedly sleeved on the outer side of the mounting section 420. The second hydraulic device 500 is located inside the side beam 400 and fixedly connected to the side plate 810 of the mounting frame 800. This connection method has a clear design intent: the mounting frame 800 is only used to limit the movement of the second hydraulic device 500. During equipment operation, the second hydraulic device 500 may experience a certain degree of shaking or displacement. The connection between the mounting frame 800 and the second hydraulic device 500 through its side plate 810 can limit excessive movement of the second hydraulic device 500 in the horizontal and vertical directions, ensuring that the second hydraulic device 500 is always in the correct working position.
[0049] The side beam 400 undertakes the task of supporting the second hydraulic device 500. As one of the main load-bearing structures of the equipment, the side beam 400 possesses sufficient strength and rigidity. By supporting the second hydraulic device 500 through the overall structure of the side beam 400, the weight and force generated by the second hydraulic device 500 can be evenly distributed to other parts of the equipment, avoiding structural damage caused by excessive localized stress. This design ensures reliable assembly between the side beam 400 and the second hydraulic device 500, enabling the second hydraulic device 500 to operate stably and providing strong support for the normal operation of the equipment.
[0050] like Figure 4 As shown, in some specific embodiments, the outer plate 820 of the mounting frame 800 is provided with a plurality of parallel mounting protrusions 821 on the end face near the side beam 400. Each mounting protrusion 821 passes between the two elongated plates 410 and is clamped and fixed by the two elongated plates 410. In this embodiment, when each elongated plate 410 is subjected to top pressure during use, it will further clamp the mounting protrusions 821, which can effectively improve the assembly reliability of the mounting frame 800 and the side beam 400.
[0051] In some specific embodiments, the extension stroke of the first hydraulic device 300 provided on the upper top seat 100 and the lower base 200 is Z, the extension stroke of the second hydraulic device 500 provided on the front and rear side beams 400 is Y, and the extension stroke of the second hydraulic device 500 provided on the left and right side beams 400 is X, satisfying: X=Y≠Z or X=Z≠Y or Y=Z≠X or X≠Y≠Z; this facilitates the asymmetrical setting of the top pressure provided by the top hammer 610 in various directions in this embodiment, making it easier to provide an asymmetrical and non-uniform pressure environment for the sample 920.
[0052] Specifically, the cylinders of the first hydraulic device 300 or the second hydraulic device 500, arranged in the three mutually perpendicular directions of x, y, and z, have asymmetrical piston lengths (36mm / 54mm / 96mm) or cylinder diameters (Φ420mm / Φ360mm / Φ300mm). (For example, x-axis piston length 36mm, y-axis piston length 54mm, z-axis piston length 96mm or x=y≠z or x≠y=z) or (for example, x-axis cylinder diameter 420mm, y-axis cylinder diameter 360mm, z-axis cylinder diameter 300mm, or x=y≠z or x≠y=z) or any combination of asymmetrical piston lengths and cylinder diameters. This allows for the configuration of the corresponding embodiment as needed, thereby providing different complex stress scenarios for the sample 920 and meeting the processing and testing requirements of the sample 920.
