Description

Technical Field

[0001] This application relates to the field of isostatic pressure equipment technology, and in particular to a horizontal isostatic pressure device and its opening and closing method. Background Technology

[0002] Isostatic pressing (IP) devices are widely used in powder material forming, material densification, and the manufacture of high-performance components. They apply uniform static pressure to the workpiece within a sealed cavity using a pressure medium, eliminating internal porosity and significantly improving the density, mechanical strength, and performance uniformity of the finished product. Therefore, they are widely used in high-end manufacturing fields such as cemented carbide, special ceramics, powder metallurgy, and aerospace composite materials. Isostatic pressing devices are generally divided into vertical and horizontal types. Vertical Isostatic pressing devices, due to the vertical lifting and lowering of materials, suffer from inconvenient loading and unloading operations, difficulties in automation integration, and low production efficiency, and are typically suitable for small-batch or small-sized workpiece production. Horizontal Isostatic pressing devices, with a horizontal layout and axial material flow, facilitate automatic material conveying and unloading, offering greater operational convenience and efficiency. They are suitable for long or large workpieces and are easier to integrate into automated production lines, thus having a wider range of applications.

[0003] A horizontal isostatic pressing device typically includes a constraint frame, a pressure-bearing cylinder placed horizontally within the constraint frame, and end plugs and a clamping mechanism for sealing the cylinder ports. The working process generally involves: first, the material to be pressed is fed into the cylinder through the cylinder ports; then, the clamping mechanism tightly presses the end plugs against the cylinder ports to form a sealed high-pressure chamber; next, high-pressure liquid is injected into the chamber for pressurization and molding; after molding, the pressure inside the chamber is released, and the end plugs are opened to remove the workpiece.

[0004] However, existing horizontal isostatic pressing devices (such as Chinese patent CN206213200U) typically use closed frames for constraint. Therefore, during loading, the cylinder must first be removed entirely from the closed frame to complete material loading and unloading before being moved back into the closed frame for pressurization. After molding, the cylinder must be removed again from the closed frame to retrieve the workpiece. Due to the high requirements for cylinder wall thickness and structural strength under ultra-high pressure conditions, the cylinder itself has a large mass and high moment of inertia. This method of repeatedly moving the heavy cylinder to load and unload materials not only results in slow opening and closing processes and low production efficiency but also extremely high energy consumption. Furthermore, within the limited equipment space, the frequent reciprocating motion of heavy components can easily lead to a series of problems such as decreased positioning accuracy, increased mechanical wear, and operational safety hazards, making it difficult to meet the demands of modern manufacturing for efficient, energy-saving, and automated production. Summary of the Invention

[0005] This application provides a horizontal isostatic pressure device and its opening and closing method, which can improve opening and closing efficiency and reliability, achieve lightweight opening and closing, and reduce opening and closing energy consumption.

[0006] To achieve the above objectives, the main technical solutions adopted in this application include: In a first aspect, embodiments of this application provide a horizontal isostatic pressing device having a first direction, a second direction, and a third direction that are perpendicular to each other, including: An ultra-high pressure vessel has an opening at one end in the first direction, and an end plug is provided in the opening; A constraint frame is disposed outside the ultra-high pressure vessel; the constraint frame has a first end portion at one end in the first direction; a material inlet / outlet channel is provided at the position corresponding to the opening on the first end portion, extending through the first direction; a moving channel is provided between the ultra-high pressure vessel and the first end portion in the first direction, extending through the constraint frame in the second direction. A clamping mechanism is located between the ultra-high pressure vessel and the first end in the first direction, and is used to limit the end plug in the first direction; An end plug transfer mechanism is provided on one side of the clamping mechanism in the second direction, for moving the end plug along the first direction to open or close the opening; A moving mechanism, located in the moving channel, is used to drive the pressing mechanism and the end plug conveying mechanism to move along the second direction.

[0007] This application proposes a horizontal isostatic pressing device that decouples the material inlet / outlet path from the end plug opening / closing path by providing an inlet / outlet channel running along the first direction and a moving channel running along the second direction. Simultaneously, through the coordinated operation of the clamping mechanism, the end plug conveying mechanism, and the moving mechanism, the automatic removal and insertion of the end plug and the overall repositioning of the clamping mechanism can be achieved. This eliminates the need to move the entire heavy cylinder for loading and unloading, significantly improving opening and closing efficiency, achieving lightweight opening and closing, reducing drive energy consumption, minimizing positioning deviations, mechanical wear, and safety risks caused by frequent reciprocating motion of heavy components, and enhancing the device's operational reliability. This better meets the demands of modern manufacturing for efficient, energy-saving, and reliable production.

[0008] Optionally, the constraint frame further includes a second end disposed opposite to the first end in the first direction and a plurality of connecting columns connecting the first end and the second end; the plurality of connecting columns are spaced apart and distributed on both sides of the ultra-high pressure vessel along the third direction, the ultra-high pressure vessel is disposed within the space enclosed by the first end, the second end and the plurality of connecting columns, and the ultra-high pressure vessel and the first end are spaced apart in the first direction to form the moving channel penetrating along the second direction.

[0009] In the above scheme, by setting the first end, the second end, and the connecting column together to form a frame structure that can accommodate the ultra-high pressure vessel, on the one hand, the constraint frame can effectively constrain the ultra-high pressure vessel, and on the other hand, the gap between the first end and the ultra-high pressure vessel in the first direction and the gap of the connecting column in the third direction can be used to naturally form a moving channel that runs through the second direction without the need for additional slotting, thereby simplifying the overall structure and improving space utilization and assembly convenience.

[0010] Optionally, the number of connecting posts is four, which are respectively connected to the four corners of the first end and the second end.

[0011] In the above scheme, by setting the connecting columns as four and arranging them at the four corners corresponding to the first end and the second end, a stable double frame structure is formed, which can evenly bear the axial expansion force generated when the ultra-high pressure vessel is working, significantly improve the torsional and bending resistance, improve the overall load-bearing capacity of the constraint frame, and ensure the reliability of the equipment's long-term operation.

[0012] Optionally, the pressing mechanism includes a pressure plate and a separation component; the pressure plate is used to press the end plug into the opening in the first direction; the separation component is used to move the end plug along the first direction so that the pressure plate and the end plug separate in the first direction to form a gap.

[0013] In the above scheme, by setting the separation component, the end plug and the pressure plate can be actively separated along the first direction to form an initial gap after the pressure is released. This can avoid jamming or excessive friction between the pressure plate and the end plug when the pressure plate moves directly along the second direction, thereby reducing the driving load of the moving mechanism and improving the smoothness and reliability of the opening and closing process.

[0014] Optionally, the pressure plate has a limiting groove adapted to the end plug on the side facing the end plug; the separation assembly includes a vertical rod, a horizontal rod, and a separation driving component; the vertical rod is movably disposed in the pressure plate along the third direction, and the end of the vertical rod that contacts the horizontal rod has an inclined portion; the horizontal rod is movably disposed in the pressure plate along the first direction, and the end of the horizontal rod that contacts the vertical rod has a ball head, and the end away from the vertical rod extends to the bottom of the limiting groove; the separation driving component can drive the vertical rod to move along the third direction, so that the horizontal rod is pushed out of the limiting groove.

[0015] In the above solution, the limiting groove accommodates and positions the end plug, which enables the end plug to maintain a stable alignment with the pressure plate and improves the clamping effect. Through the cooperation between the inclined part and the ball head, the movement of the vertical rod along the third direction is converted into the movement of the horizontal rod along the first direction, realizing the stable pushing and separation of the end plug in a narrow space. The structure is compact and the transmission efficiency is high.

[0016] Optionally, the clamping mechanism further includes a reset assembly for driving the crossbar to move away from the end plug in the first direction.

[0017] In the above scheme, by setting the reset component, the crossbar can be automatically reset after the separation action is completed, thereby avoiding physical interference between the crossbar and the end plug and ensuring the continuous and automated operation of the device.

[0018] Optionally, the reset assembly includes an annular end cap, a collar, and an elastic element; the annular end cap is fixed to the bottom of the limiting groove; the collar is fixedly sleeved on the crossbar; and the elastic element abuts against the annular end cap and the collar along the first direction.

[0019] In the above solution, the automatic reset of the crossbar can be achieved simply and quickly through the cooperation of the annular end cap, the collar and the elastic element. The structure is simple and reliable, requires no additional power source, and can reduce manufacturing costs.

[0020] Optionally, the end plug transfer mechanism includes a gripping component and a gripping drive component; the gripping component is used to grip or release the end plug; the gripping drive component is connected to the gripping component and is used to drive the gripping component to move along the first direction.

[0021] In the above scheme, the automatic gripping, release and axial movement of the end plug can be realized simply and conveniently through the cooperation of the gripping component and the gripping drive component, thereby realizing the reliable removal or insertion of the end plug.

[0022] Optionally, the end plug transfer mechanism further includes an end plug frame, the end plug frame having a receiving cavity adapted to the end plug and capable of accommodating the end plug; the end plug frame having the gripping drive assembly on both sides in the second direction respectively; the gripping assembly being disposed in the receiving cavity on one side in the first direction and connected to the two gripping drive assemblies.

[0023] In the above scheme, the end plug is guided and limited by the end plug frame, and a dual-side drive structure is adopted to realize dual-side synchronous drive of the gripping component, improve the motion stability of the gripping component, avoid off-center load, and thus effectively improve the stability and positioning accuracy of the transfer process.

[0024] Optionally, the inner wall of the end plug frame is provided with a plurality of universal ball bearings extending along the first direction.

[0025] In the above scheme, by providing the universal ball strip on the inner wall of the end plug frame, rolling support can be provided during the movement of the end plug, reducing the frictional resistance between the end plug and the end plug frame, and facilitating the smooth entry and exit of the end plug.

[0026] Optionally, the gripping assembly includes an electromagnet, a mounting bracket, and a connecting rod; the connecting rod is connected to the gripping drive assembly; the mounting bracket is disposed on the connecting rod; the electromagnet is mounted on the mounting bracket for attracting or releasing the end plug.

[0027] In the above solution, by using the electromagnet as the gripping element, non-contact adsorption and release of the end plug can be achieved, which can avoid wear and positioning deviation that may be caused by mechanical clamping, extend service life, and at the same time, the control is simple and the response speed is fast.

[0028] Optionally, the gripping drive assembly includes a gear, a rack, a guide rail, and a motor; the gear is connected to the output end of the motor; the rack extends along the first direction and meshes with the gear; the guide rail extends along the first direction; the gripping assembly is slidably disposed on the guide rail and fixedly connected to the gear.

[0029] In the above scheme, through the transmission cooperation between the gear and the rack and the guidance of the guide rail, the gripping component can move smoothly along the first direction, thereby accurately inserting / removing the end plug, with rapid response and reliable control.

[0030] Optionally, the end plug transfer mechanism is further provided with a position sensor, which is used to detect the relative position of the gripping component and the end plug to achieve alignment.

[0031] In the above scheme, by setting the position sensor, the precise alignment between the gripping component and the end plug can be achieved, so that the electromagnet can accurately attract the end plug, avoiding attraction failure or collision damage caused by alignment deviation, and improving the safety and reliability of the device.

[0032] Optionally, the moving mechanism includes a slide plate, a slide rail, and a sliding drive assembly. The slide plate is used to carry the pressing mechanism and the end plug conveying mechanism. The slide rail is disposed in the moving channel along the second direction and is slidably connected to the slide plate. The sliding drive assembly is used to drive the slide plate to move along the second direction.

[0033] In the above scheme, through the cooperation of the slide plate, the slide rail and the sliding drive assembly, the pressing mechanism and the end plug transfer mechanism can move synchronously and smoothly in the second direction, reliably realizing the overall relocation and reset of the pressing mechanism and the end plug transfer mechanism, and improving the opening and closing efficiency and reliability of the device.

[0034] Secondly, embodiments of this application provide a method for opening and closing a horizontal isostatic pressure device based on the above-mentioned method, comprising the following steps: S1: The moving mechanism drives the pressing mechanism to move along the second direction, so as to release the end plug from the pressing state; S2: The moving mechanism drives the end plug transfer mechanism to move along the second direction to one side of the end plug in the first direction; S3: The end plug transfer mechanism moves the end plug along the first direction so that the end plug is disengaged from the opening; S4: The moving mechanism drives the end plug transfer mechanism to move along the second direction away from the opening; S5: The material is fed into the ultra-high pressure vessel along the first direction through the inlet / outlet channel and the opening; S6: The moving mechanism drives the end plug transfer mechanism to move along the second direction to one side of the end plug in the first direction; S7: The end plug transfer mechanism moves the end plug along the first direction so that the end plug blocks the opening; S8: The moving mechanism drives the end plug transfer mechanism to move along the second direction in a direction away from the opening; S9: The moving mechanism drives the pressing mechanism to move along the second direction to the side of the end plug in the first direction; S10: The pressing mechanism presses the end plug into the opening in the first direction.

[0035] This application proposes a method for opening and closing a horizontal isostatic pressing device. Material is loaded and unloaded through the feed / discharge channel extending along the first direction. The pressing mechanism and the end-plug transfer mechanism are moved within the moving channel along the second direction to expose the opening. This spatially staggers the material loading / unloading actions and the end-plug opening / closing actions, executing them step-by-step in sequence, thereby decoupling the material loading / unloading path from the end-plug opening / closing path. Through the step-by-step coordinated actions of the moving mechanism, the end-plug transfer mechanism, and the pressing mechanism, automatic insertion and removal of the end-plug and overall repositioning of the pressing mechanism can be achieved. This eliminates the need to move the entire heavy cylinder for loading and unloading, significantly improving opening and closing efficiency, achieving lightweight opening and closing, reducing drive energy consumption, minimizing positioning deviations, mechanical wear, and safety risks caused by frequent reciprocating movements of heavy components, and enhancing the device's operational reliability. This better meets the demands of modern manufacturing for efficient, energy-saving, and reliable production.

[0036] Optionally, in step S1, before the moving mechanism drives the pressing mechanism to move along the second direction, the following steps are performed: the pressing mechanism moves the end plug along the first direction so that the pressing mechanism and the end plug separate in the first direction to form a gap.

[0037] In the above scheme, by actively separating the end plug and the pressing mechanism along the first direction to form an initial gap before the moving mechanism drives the pressing mechanism to move along the second direction, it is possible to avoid jamming or excessive friction between the pressing mechanism and the end plug when the pressing mechanism moves directly along the second direction, thereby reducing the driving load of the moving mechanism and improving the smoothness and reliability of the opening and closing process.

[0038] Optionally, in steps S3 and S7, the end plug transfer mechanism drives the end plug to move along the first direction after the end plug is attracted by the electromagnet being energized.

[0039] In the above solution, by using an electromagnet to energize and hold the end plug, non-contact adsorption and release of the end plug can be achieved, which can avoid wear and positioning deviation that may be caused by mechanical clamping, extend service life, and at the same time, it is simple to control and has a fast response speed.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

[0045] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0047] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0049] A horizontal isostatic pressing device typically includes a constraint frame, a pressure-bearing cylinder placed horizontally within the constraint frame, and end plugs and a clamping mechanism for sealing the cylinder ports. The working process generally involves: first, the material to be pressed is fed into the cylinder through the cylinder ports; then, the clamping mechanism tightly presses the end plugs against the cylinder ports to form a sealed high-pressure chamber; next, high-pressure liquid is injected into the chamber for pressurization and molding; after molding, the pressure inside the chamber is released, and the end plugs are opened to remove the workpiece.

[0050] However, existing horizontal isostatic pressing devices typically use closed frames for constraint. Therefore, during loading, the cylinder must first be removed entirely from the closed frame to complete material loading and unloading before being moved back into the closed frame for pressurization. After pressing, the cylinder must be removed again from the closed frame to retrieve the workpiece. Due to the high requirements for cylinder wall thickness and structural strength under ultra-high pressure conditions, the cylinder itself has a large mass and high moment of inertia. This method of repeatedly moving the heavy cylinder to load and unload materials not only results in slow opening and closing processes and low production efficiency but also extremely high energy consumption. Furthermore, within the limited equipment space, the frequent reciprocating motion of heavy components can easily lead to a series of problems such as decreased positioning accuracy, increased mechanical wear, and operational safety hazards, making it difficult to meet the demands of modern manufacturing for efficient, energy-saving, and automated production.

[0051] In view of this, in order to improve opening and closing efficiency and reliability, achieve lightweight opening and closing, and reduce opening and closing energy consumption, this application provides a novel horizontal isostatic pressure device.

[0052] In this embodiment, the horizontal axial direction of the horizontal isostatic pressure device is defined as the first direction X, the horizontal transverse direction as the second direction Y, and the vertical direction as the third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are mutually perpendicular.

[0053] Please refer to Figure 1 and Figure 2 The horizontal isostatic pressure device includes an ultra-high pressure vessel 1, a constraint frame 2, a clamping mechanism 3, an end plug transfer mechanism 4, and a moving mechanism 5, wherein: The ultra-high pressure vessel 1 is used to contain materials and achieve isostatic pressing under the action of a high-pressure medium; specifically, such as... Figure 8 , Figure 9 As shown, the ultra-high pressure vessel 1 has an opening 11 at one end in the first direction X for material loading and unloading, and an end plug 12 is provided in the opening 11 for sealing the opening 11.

[0054] The constraint frame 2 is disposed outside the ultra-high pressure vessel 1; specifically, as shown in the figure... Figure 7 , Figure 8 As shown, the constraint frame 2 has a first end 21 at one end in the first direction X, and a feeding / discharging channel 24 is provided at the position corresponding to the opening 11 along the first direction X; in the first direction X, a moving channel 25 is provided between the ultra-high pressure vessel 1 and the first end 21 along the second direction Y through the constraint frame 2, for the movement of the pressing mechanism 3 and the end plug conveying mechanism 4.

[0055] The clamping mechanism 3 is located between the ultra-high pressure vessel 1 and the first end 21 in the first direction X, and is used to limit the end plug 12 in the first direction X; for example Figure 9 As shown, in the working state, the clamping mechanism 3 firmly presses the end plug 12 into the opening 11 to ensure reliable sealing.

[0056] The end plug transfer mechanism 4 is located on one side of the pressing mechanism 3 in the second direction Y, and is used to move the end plug 12 along the first direction X so that the opening 11 is opened or closed; specifically, in the non-working state, the end plug transfer mechanism 4 can grab, remove or reinstall the end plug 12 to realize the opening and closing of the opening 11.

[0057] The moving mechanism 5 is disposed in the moving channel 25 and is used to drive the pressing mechanism 3 and the end plug transferring mechanism 4 to move along the second direction Y. Specifically, the pressing mechanism 3 and the end plug transferring mechanism 4 can be driven synchronously by the moving mechanism 5, or they can be driven step by step by the moving mechanism 5; there is no limitation here.

[0058] The specific operation process of the horizontal isostatic pressure device is as follows: When it is necessary to open the horizontal isostatic pressing device for unloading or loading, such as Figure 3 , Figure 4 As shown, firstly, the moving mechanism 5 drives the pressing mechanism 3 to move along the second direction Y, causing the pressing mechanism 3 to release the pressing state on the end plug 12. Then, the moving mechanism 5 drives the end plug transferring mechanism 4 to move along the second direction Y, causing the end plug transferring mechanism 4 to move to the side of the end plug 12 in the first direction X. Next, the end plug transferring mechanism 4 moves the end plug 12 along the first direction X, causing the end plug 12 to disengage from the opening 11. Afterwards, as... Figure 5 , Figure 6 As shown, the moving mechanism 5 drives the end plug conveying mechanism 4 and the end plug 12 held therein to move along the second direction Y in a direction away from the opening 11, exposing the opening 11. At this time, the material can be fed into the ultra-high pressure vessel 1 along the first direction X through the inlet / outlet channel 24 and the opening 11, or the processed material can be taken out from the ultra-high pressure vessel 1.

[0059] When it is necessary to shut down the horizontal isostatic pressing device for pressure molding, such as Figure 3 , Figure 4 As shown, firstly, the moving mechanism 5 drives the end plug transfer mechanism 4 to move along the second direction Y, so that the end plug 12 held by the end plug transfer mechanism 4 is aligned with the opening 11 in the first direction X. Then, the end plug transfer mechanism 4 moves the end plug 12 along the first direction X, so that the end plug 12 enters and seals the opening 11. Afterwards, as... Figure 1 , Figure 2 As shown, the moving mechanism 5 drives the end plug transfer mechanism 4 to move away from the opening 11 along the second direction Y, so that the end plug transfer mechanism 4 separates from the end plug 12; the moving mechanism 5 drives the pressing mechanism 3 to move along the second direction Y to the side of the end plug 12 in the first direction X, and presses the end plug 12 into the opening 11 along the first direction X, so that high pressure medium can be injected into the ultra-high pressure container 1 for pressurization and molding.

[0060] This application proposes a horizontal isostatic pressing device. By setting a feed / discharge channel 24 running through the first direction X and a moving channel 25 running through the second direction Y, the material feed / discharge path and the end plug opening / closing path are decoupled. Simultaneously, through the coordinated operation of the clamping mechanism 3, the end plug conveying mechanism 4, and the moving mechanism 5, the automatic removal and insertion of the end plug 12 and the overall repositioning of the clamping mechanism 3 can be achieved. This eliminates the need to move the entire heavy cylinder for loading and unloading, significantly improving opening and closing efficiency, achieving lightweight opening and closing, reducing drive energy consumption, minimizing positioning deviations, mechanical wear, and safety risks caused by frequent reciprocating motion of heavy components, and enhancing the device's operational reliability. This better meets the demands of modern manufacturing for efficient, energy-saving, and reliable production.

[0061] In other embodiments, such as Figure 7 , Figure 8 As shown, the constraint frame 2 further includes a second end 22 disposed opposite to the first end 21 in the first direction X, and a plurality of connecting columns 23 connecting the first end 21 and the second end 22; the plurality of connecting columns 23 are spaced apart and distributed along the third direction Z on both sides (and the upper and lower sides in this embodiment) of the ultra-high pressure vessel 1, the ultra-high pressure vessel 1 is disposed within the space enclosed by the first end 21, the second end 22 and the plurality of connecting columns 23, and the ultra-high pressure vessel 1 and the first end 21 are spaced apart in the first direction X to form the moving channel 25 extending along the second direction Y. Specifically, the number of connecting columns 23 can be two, three, four, five, six or more, and their cross-sectional shape can be circular, square, etc., without limitation here.

[0062] In the above scheme, by setting the first end 21, the second end 22 and the connecting column 23 together to form a frame structure that can accommodate the ultra-high pressure vessel 1, on the one hand, the constraint frame 2 can effectively constrain the ultra-high pressure vessel 1, and on the other hand, the gap between the first end 21 and the ultra-high pressure vessel 1 in the first direction X and the gap between the connecting column 23 in the third direction Z can be used to naturally form a moving channel 25 that runs through the second direction Y, without the need for additional slotting, thereby simplifying the overall structure and improving space utilization and assembly convenience.

[0063] In other embodiments, there are four connecting posts 23, which respectively connect the four corners of the first end 21 and the second end 22 to form a double-frame structure. The connection method between the connecting posts 23 and the first end 21 and the second end 22 can be welding, threaded connection or wire winding connection, etc., and there is no limitation here.

[0064] In the above scheme, by setting the connecting columns 23 as four and arranging them at the four corners corresponding to the first end 21 and the second end 22, a stable double frame structure is formed, which can uniformly bear the axial expansion force generated when the ultra-high pressure vessel 1 is working, significantly improve the torsional and bending resistance, improve the overall load-bearing capacity of the constraint frame 2, and ensure the reliability of the equipment's long-term operation.

[0065] In other embodiments, such as Figure 10 As shown, the clamping mechanism 3 includes a pressure plate 31 and a separation component 32. The pressure plate 31 is used to press the end plug 12 into the opening 11 in the first direction X; the separation component 32 is used to move the end plug 12 along the first direction X, so that the pressure plate 31 and the end plug 12 separate in the first direction X, forming a gap. Specifically, the separation component 32 can achieve separation using a mechanical pushing method, a hydraulic drive method, etc., and is not limited here.

[0066] In the above scheme, by setting the separation component 32, the end plug 12 and the pressure plate 31 can be actively separated along the first direction X to form an initial gap after the pressure is released. This can avoid jamming or excessive friction between the pressure plate 31 and the end plug 12 when the pressure plate 31 moves directly along the second direction Y, thereby reducing the driving load of the moving mechanism 5 and improving the smoothness and reliability of the opening and closing process.

[0067] In other embodiments, such as Figure 10 As shown, the pressure plate 31 has a limiting groove 311 on the side facing the end plug 12, which is adapted to the end plug 12. The limiting groove 311 is used to accommodate and position the end plug 12, so that the end plug 12 and the pressure plate 31 maintain a stable alignment relationship. Figure 11 , Figure 12 As shown, the separation assembly 32 includes a vertical rod 321, a horizontal rod 322, and a separation drive component. The vertical rod 321 is movably disposed within the pressure plate 31 along the third direction Z, and the end of the vertical rod 321 that contacts the horizontal rod 322 has an inclined portion 3211. The horizontal rod 322 is movably disposed within the pressure plate 31 along the first direction X, and the end of the horizontal rod 322 that contacts the vertical rod 321 has a ball head 3221, with the end away from the vertical rod 321 extending to the bottom of the limiting groove 311. The separation drive component can drive the vertical rod 321 to move along the third direction Z, so that the horizontal rod 322 is pushed out of the limiting groove 311. Specifically, the separation drive component can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc., and is not limited here.

[0068] In the above scheme, by using the limiting groove 311 to accommodate and position the end plug 12, the end plug 12 and the pressure plate 31 can maintain a stable alignment relationship, improving the pressing effect; by using the cooperation between the inclined part 3211 and the ball head 3221, the movement of the vertical rod 321 along the third direction Z is converted into the movement of the horizontal rod 322 along the first direction X, realizing the stable pushing and separation of the end plug 12 in a narrow space, with a compact structure and high transmission efficiency.

[0069] In other embodiments, such as Figure 10 , Figure 11 As shown, the clamping mechanism 3 also includes a reset component 33, which is used to drive the crossbar 322 to move away from the end plug 12 in the first direction X, so that the crossbar 322 can be automatically pulled back to its original position after the separation action is completed.

[0070] In the above scheme, by setting the reset component 33, the crossbar 322 can be automatically reset after the separation action is completed, thereby avoiding physical interference between the crossbar 322 and the end plug 12 and ensuring the continuous and automated operation of the device.

[0071] In other embodiments, such as Figure 12 , Figure 13 As shown, the reset assembly 33 includes an annular end cap 331, a collar 332, and an elastic element 333; the annular end cap 331 is fixed to the bottom of the limiting groove 311; the collar 332 is fixedly sleeved on the crossbar 322; the elastic element 333 abuts against the annular end cap 331 and the collar 332 along the first direction X; specifically, the elastic element 333 can be a helical spring, a spring sheet, etc., which is not limited here. When the separation drive component drives the vertical rod 321 to move along the third direction Z, and the horizontal rod 322 pushes out towards the end plug 12 along the first direction X under the cooperation of the inclined part 3211 and the ball head 3221, the collar 332 moves synchronously with the horizontal rod 322, and the elastic element 333 is compressed between the annular end cap 331 and the collar 332 and stores elastic potential energy; when the separation action is completed and the separation drive component is reset, the vertical rod 321 moves upward, releasing the thrust on the horizontal rod 322, and the elastic element 333 releases the stored elastic potential energy, pushing the collar 332 and the horizontal rod 322 to move away from the end plug 12 along the first direction X, so that the horizontal rod 322 automatically resets.

[0072] In the above solution, the automatic reset of the crossbar 322 can be achieved simply and quickly through the cooperation of the annular end cap 331, the collar 332 and the elastic element 333. The structure is simple and reliable, requires no additional power source, and can reduce manufacturing costs.

[0073] In other embodiments, such as Figure 14 , Figure 15 As shown, the end plug transfer mechanism 4 includes the gripping component 41 and the gripping drive component 42; the gripping component 41 is used to grip or release the end plug 12; the gripping drive component 42 is connected to the gripping component 41 and is used to drive the gripping component 41 to move along the first direction X. Specifically, the gripping component 41 can use electromagnetic adsorption, vacuum adsorption, or mechanical clamping to achieve gripping, etc., without limitation here; the gripping drive component 42 can use lead screw drive, gear and rack drive, or cylinder drive, etc., without limitation here.

[0074] In the above scheme, the automatic gripping, releasing and axial movement of the end plug 12 can be realized simply and conveniently through the cooperation of the gripping component 41 and the gripping drive component 42, thereby realizing the reliable removal or insertion of the end plug 12.

[0075] In some other embodiments, the end plug transfer mechanism 4 further includes the end plug frame 43, which has a receiving cavity 431 adapted to the end plug 12 and capable of accommodating the end plug 12; the end plug frame 43 has gripping drive components 42 on both sides in the second direction Y; the gripping component 41 is located inside the receiving cavity 431 on one side in the first direction X and is connected to the two gripping drive components 42, and the two gripping drive components 42 can synchronously drive the gripping component 41 to move to ensure balanced force.

[0076] In the above scheme, the end plug 12 is guided and limited by the end plug frame 43, and a dual-side drive structure is adopted to realize dual-side synchronous drive of the gripping component 41, improve the motion stability of the gripping component 41, avoid off-center load, and thus effectively improve the stability and positioning accuracy of the transfer process.

[0077] In other embodiments, the inner wall of the end plug frame 43 is provided with a plurality of universal ball bearing strips 432 extending along the first direction X. The surface of each universal ball bearing strip 432 is embedded with a plurality of freely rolling balls, providing multi-directional rolling support. Specifically, the number of universal ball bearing strips 432 can be two, three, four, or more, and is not limited here; preferably, a plurality of the universal ball bearing strips 432 are evenly distributed circumferentially on the inner wall of the end plug frame 43.

[0078] In the above scheme, by providing the universal ball bearing 432 on the inner wall of the end plug frame 43, rolling support can be provided during the movement of the end plug 12, reducing the frictional resistance between the end plug 12 and the end plug frame 43, and facilitating the smooth entry and exit of the end plug 12.

[0079] In other embodiments, the gripping assembly 41 includes an electromagnet 411, a mounting bracket 412, and a connecting rod 413; the connecting rod 413 is connected to the gripping drive assembly 42; the mounting bracket 412 is disposed on the connecting rod 413; the electromagnet 411 is mounted on the mounting bracket 412 for attracting or releasing the end plug 12. Specifically, the end plug 12 may be made of a magnetically conductive material, such as stainless steel, to accommodate the operation of the electromagnet 411.

[0080] In the above scheme, by using the electromagnet 411 as the gripping element, non-contact adsorption and release of the end plug 12 can be achieved, which can avoid wear and positioning deviation that may be caused by mechanical clamping, extend service life, and at the same time, the control is simple and the response speed is fast.

[0081] In other embodiments, the gripping drive assembly 42 includes a gear 421, a rack 422, a guide rail 423, and a motor 424; the gear 421 is connected to the output end of the motor 424; the rack 422 extends along the first direction X and meshes with the gear 421; the guide rail 423 extends along the first direction X; the gripping assembly 41 is slidably disposed on the guide rail 423 and fixedly connected to the gear 421. Specifically, the motor 424 may be a servo motor, a stepper motor, or a speed-regulating motor, etc., without limitation; the fixed connection method between the connecting rod 413 and the gear 421 may be welding, threaded connection, or integral molding, etc., without limitation. When the motor 424 drives the gear 421 to rotate, the gear 421 moves relative to the rack 422, thereby driving the connecting rod 413 to slide along the guide rail 423, so as to realize the movement of the gripping assembly 41 along the first direction X.

[0082] In the above scheme, through the transmission cooperation between the gear 421 and the rack 422 and the guidance of the guide rail 423, the gripping component 41 can move smoothly along the first direction X, thereby accurately inserting / removing the end plug 12, with rapid response and reliable control.

[0083] In some embodiments, the end plug transfer mechanism 4 is further provided with a position sensor, which is used to detect the relative position of the gripping component 41 and the end plug 12 to achieve alignment. Specifically, the position sensor may be a photoelectric switch, a proximity switch, or a vision sensor, etc., without limitation; the position sensor may be disposed on the end plug frame 43 or the gripping component 41, without limitation.

[0084] In the above scheme, by setting the position sensor, the precise alignment between the gripping component 41 and the end plug 12 can be achieved, so that the electromagnet 411 can accurately attract the end plug 12, avoiding attraction failure or collision damage caused by alignment deviation, and improving the safety and reliability of the device.

[0085] In other embodiments, such as Figure 1 As shown, the moving mechanism 5 includes the slide plate 51, the slide rail 52, and the sliding drive assembly 53. The slide plate 51 is used to support the pressing mechanism 3 and the end plug conveying mechanism 4. The slide rail 52 is disposed along the second direction Y in the moving channel 25 and is slidably connected to the slide plate 51. The sliding drive assembly 53 is used to drive the slide plate 51 to move along the second direction Y. Specifically, the sliding drive assembly 53 can be a motor-driven lead screw mechanism, gear and rack mechanism, sprocket and chain mechanism, etc., and is not limited here.

[0086] In the above scheme, through the cooperation of the slide plate 51, the slide rail 52 and the sliding drive assembly 53, the pressing mechanism 3 and the end plug transfer mechanism 4 can move synchronously and smoothly in the second direction Y, reliably realizing the overall relocation and reset of the pressing mechanism 3 and the end plug transfer mechanism 4, and improving the opening and closing efficiency and reliability of the device.

[0087] This application also provides an opening and closing method based on the above-mentioned horizontal isostatic pressure device, including the following steps: S1: The moving mechanism 5 drives the pressing mechanism 3 to move along the second direction Y, so that the end plug 12 is released from the pressing state; S2: The moving mechanism 5 drives the end plug transfer mechanism 4 to move along the second direction Y to the side of the end plug 12 in the first direction X; S3: The end plug transfer mechanism 4 moves the end plug 12 along the first direction X so that the end plug 12 disengages from the opening 11; S4: The moving mechanism 5 drives the end plug transfer mechanism 4 to move along the second direction Y in a direction away from the opening 11; S5: The material is fed into the ultra-high pressure vessel 1 along the first direction X through the inlet / outlet channel 24 and the opening 11; S6: The moving mechanism 5 drives the end plug transfer mechanism 4 to move along the second direction Y to the side of the end plug 12 in the first direction X; S7: The end plug transfer mechanism 4 moves the end plug 12 along the first direction X so that the end plug 12 blocks the opening 11; S8: The moving mechanism 5 drives the end plug transfer mechanism 4 to move along the second direction Y in a direction away from the opening 11; S9: The moving mechanism 5 drives the pressing mechanism 3 to move along the second direction Y to the side of the end plug 12 in the first direction X; S10: The pressing mechanism 3 presses the end plug 12 into the opening 11 in the first direction X.

[0088] In the above steps, the timing control between each step can be implemented using a programmable logic controller (PLC) or an industrial computer, and there is no limitation here; the movement speed and position of the end plug transfer mechanism 4 and the pressing mechanism 3 can be adjusted according to the actual working conditions, and there is no limitation here; interlocking logic is provided between each step to ensure safety.

[0089] This application proposes a method for opening and closing a horizontal isostatic pressing device. Material is loaded and unloaded through the feed / discharge channel 24 extending along the first direction X. The pressing mechanism 3 and the end plug conveying mechanism 4 are moved within the moving channel 25 along the second direction Y to expose the opening 11. This spatially separates the material loading / unloading actions from the end plug opening / closing actions, and executes them step-by-step in sequence, thereby decoupling the material loading / unloading path from the end plug opening / closing path. Through the step-by-step coordinated actions of the moving mechanism 5, the end plug conveying mechanism 4, and the pressing mechanism 3, the automatic removal and insertion of the end plug 12 and the overall repositioning of the pressing mechanism 3 can be achieved. This eliminates the need to move the entire heavy cylinder for loading and unloading, significantly improving opening and closing efficiency, achieving lightweight opening and closing, reducing drive energy consumption, minimizing positioning deviations, mechanical wear, and safety risks caused by frequent reciprocating motion of heavy components, and enhancing the operational reliability of the device. This better meets the demands of modern manufacturing for efficient, energy-saving, and reliable production.

[0090] In some other embodiments, before the moving mechanism 5 drives the pressing mechanism 3 to move along the second direction Y in step S1, the following steps are performed: the pressing mechanism 3 moves the end plug 12 along the first direction X so that the pressing mechanism 3 and the end plug 12 separate in the first direction X to form a gap.

[0091] In the above scheme, before the moving mechanism 5 drives the pressing mechanism 3 to move along the second direction Y, the end plug 12 and the pressing mechanism 3 are actively separated along the first direction X to form an initial gap. This can prevent the pressing mechanism 3 from getting stuck or generating excessive friction with the end plug 12 when it moves directly along the second direction Y, thereby reducing the driving load of the moving mechanism 5 and improving the smoothness and reliability of the opening and closing process.

[0092] In other embodiments, in steps S3 and S7, the end plug transfer mechanism 4 drives the end plug 12 to move along the first direction X after the end plug 12 is attracted by the electromagnet being energized.

[0093] In the above scheme, by using an electromagnet to energize and hold the end plug 12, non-contact adsorption and release of the end plug 12 can be achieved, which can avoid wear and positioning deviation that may be caused by mechanical clamping, extend service life, and at the same time, the control is simple and the response speed is fast.
