Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to an isostatic pressing device. Background Technology

[0002] During battery production, battery cells need to undergo isostatic pressing. Isostatic pressing refers to loading the battery cells into a cylinder, inserting plugs into opposite ends of the cylinder, and introducing a working medium to pressurize the cylinder, thereby densifying the battery cells loaded inside.

[0003] When the plug is inserted into the cylinder, the high pressure inside the cylinder exerts a reverse force on the plug, resulting in a significant force on the drive component that moves the plug. When the force exerted on the plug by the high-pressure environment inside the cylinder exceeds the driving force applied by the drive component, the plug will be pushed out of the cylinder, causing the plug to fail and thus affecting the isostatic pressing effect of the isostatic pressing equipment. Utility Model Content

[0004] The purpose of this application is to provide an isostatic pressing device, which aims to solve the problem that the plug of the isostatic pressing device may fail to move out due to high internal pressure during use.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] This application provides an isostatic pressing device, including a frame, an isostatic pressing chamber, and an insertion mechanism. A working chamber is formed through the interior of the frame along a first direction. The isostatic pressing chamber is disposed within the working chamber and is used to accommodate individual battery cells. Openings communicating with the interior are formed on opposite sides of the isostatic pressing chamber along a second direction, with the first direction perpendicular to the second direction. An insertion mechanism is provided on opposite sides of the frame along the second direction. The insertion mechanism includes a support base, a plug, a first driving member, and an abutment member. The first driving member is disposed on the support base, and the plug is disposed within the working chamber. The first driving member is driven and connected to the plug, and is configured to move the plug along the second direction so that the plug is inserted into the opening. The abutment member is movably disposed on the support base, and is configured to move into the gap between the frame and the plug along the second direction when the plug is inserted into the opening, and is supported by the plug and the frame.

[0007] The beneficial effects of the embodiments of this application are as follows: The isostatic pressing equipment provided in this application embodiment sets the isostatic pressing chamber in the working cavity of the frame. The first driving member of the insertion mechanism at opposite ends of the frame drives the plug to move along the second direction to be inserted into the opening, so that the plug is used to seal the opening of the isostatic pressing chamber and provide working medium into the opening to realize the isostatic pressing operation. At the same time, when the plug is inserted into the opening, the abutment can also be moved into the gap between the frame and the plug along the second direction. When the high pressure environment inside the isostatic pressing chamber exerts a force on the plug that is greater than the driving force applied by the first driving member, so that the plug tends to move out of the opening, the abutment can abut against the frame and support the plug, thereby reducing the probability of the plug moving out of the opening and causing failure, and thus improving the reliability of the isostatic pressing equipment.

[0008] In some embodiments, the insertion mechanism further includes a floating member, which is movably disposed on the support base along the second direction; and an abutment member is movably disposed on the floating member.

[0009] By adopting the above technical solution, the abutting part is movably set on the floating part, and the floating part is movably set on the support seat in the second direction. In this way, when the abutting part moves to the gap between the frame and the plug for abutting support, the abutting part can move relative to the support seat in the second direction in sync with the floating part to a certain extent for floating adjustment, thereby effectively reducing the probability of damage caused by dry friction of the abutting part.

[0010] In some embodiments, the insertion mechanism further includes a second drive member disposed on the floating member, the output end of the second drive member being connected to the abutment member; when the plug is inserted into the opening, the second drive member is configured to move the abutment member into the gap between the frame and the plug in a second direction.

[0011] By adopting the above technical solution, the abutment can be moved by the second driving member set on the floating member, so that the abutment can slide along the first direction into the gap between the frame and the plug along the second direction under the action of the second driving member.

[0012] In some embodiments, the output direction of the second drive is parallel to the first direction.

[0013] By adopting the above technical solution, the abutment can move relative to the floating member in the first direction under the action of the second driving member, and the moving direction of the abutment is perpendicular to the moving direction of the plug, so the abutment has a low impact on the moving path of the plug.

[0014] In some embodiments, the insertion mechanism further includes an elastic limiting member, with its opposite ends acting on the floating member and the support base respectively along the second direction.

[0015] By adopting the above technical solution, the elastic limiting member acts on the floating member along the second direction, so that the elastic limiting member is used to elastically limit the floating member, thereby realizing the elastic floating adjustment of the floating member and the abutment member relative to the support seat along the second direction.

[0016] In some embodiments, the elastic limiting member includes a connecting post and an elastic part. The surface of the connecting post is provided with an abutting protrusion. One end of the connecting post along the second direction is fitted with the elastic part so that the elastic part abuts against the abutting protrusion. The floating member is also provided with a through hole. One end of the connecting post fitted with the elastic part passes through the through hole so that the elastic part abuts against the floating member. The other end of the connecting post abuts against the support base.

[0017] By adopting the above technical solution, when the abutment is supported between the plug and the frame in the second direction, the floating part can move synchronously with the abutment and squeeze the elastic part in the second direction. When the abutment loses the force applied by the plug, the elastic part can apply an elastic restoring force to the floating part, so that the floating part and the abutment can move back to their original positions in the second direction, thereby achieving the floating adjustment effect of the floating part and the abutment.

[0018] In some embodiments, a channel is provided on at least one side surface of the abutment along the second direction, and the channel communicates to the outside of the abutment in a direction perpendicular to the second direction.

[0019] By adopting the above technical solution, and by setting a channel on the surface of the abutment, when the abutment is used to support between the plug and the frame, the channel can effectively reduce the probability that the surface of the abutment will adhere and adhere to the plug or frame during the support process.

[0020] In some embodiments, the insertion mechanism further includes a guide structure, which includes a guide portion and a sliding portion. The guide portion is connected to the support base, and the sliding portion is slidably disposed on the guide portion along a second direction. The sliding portion is connected to the plug.

[0021] By adopting the above technical solution, the sliding part forms a sliding fit with the guide part along the second direction to achieve the moving guidance function of the plug, thereby improving the stability of the plug movement.

[0022] In some embodiments, the floating member is movably disposed on the sliding portion along the second direction.

[0023] By adopting the above technical solution, the floating member can move relative to the sliding part in the second direction, so as to realize the floating adjustment of the floating member and the abutment member provided on the floating member in the second direction.

[0024] In some embodiments, the floating member is provided with a mounting portion, and the mounting portion and the sliding portion slide in a second direction.

[0025] By adopting the above technical solution, the mounting part and the sliding part form a sliding fit along the second direction. When the abutment is used to support between the plug and the frame, the abutment can slide and adjust synchronously with the floating part on the sliding part.

[0026] In some embodiments, the output end of the first driving member is connected to the sliding part.

[0027] By adopting the above technical solution, the first driving component can be used to control the sliding part to slide according to the guiding action of the guide part, thereby making the sliding part drive the plug to move more stably.

[0028] In some embodiments, the support base includes a plurality of support surfaces that are spaced apart and parallel to each other. Each of the plurality of support surfaces is provided with a first driving member and a guide portion of a guide structure. Furthermore, the output end of the first driving member is connected to a sliding portion of the guide structure provided on the same support surface.

[0029] By adopting the above technical solution, and by simultaneously using the first driving component to drive the sliding component of the corresponding guiding structure on multiple support surfaces to guide the sliding, the stability of the plug movement can be further improved.

[0030] In some embodiments, the support base includes a support bottom and two support connecting portions spaced apart on the support bottom along a first direction; along the first direction, the side surface of the two support connecting portions facing away from each other is a support surface; along the second direction, the opposite sides of the frame are respectively inserted between the two support connecting portions of the support base on the corresponding side.

[0031] By adopting the above technical solution, two spaced-apart support connecting parts are used to form a support surface for installing the first driving member. At the same time, the gap between the two support connecting parts can also be used to avoid the frame, so that the support connecting parts and the frame do not form a connection relationship. In this way, when the frame deforms under the action of the abutment, the movement of the plug driven by the first driving member is less affected, thus effectively reducing the impact on the concentricity of the plug when it is inserted into the opening.

[0032] In some embodiments, the support base further includes at least three equal-height columns, each of which is disposed parallel to the first direction between two support connection portions; the opposite ends of the equal-height columns are respectively connected to the support connection portions on the corresponding sides.

[0033] By adopting the above technical solution, by setting at least three equal-height columns between and connecting the two support connection parts in a manner parallel to the first direction, the parallelism of the support surfaces of the two support connection parts is effectively guaranteed.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0049] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in industrial equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0053] In the battery production process, isostatic pressing is required for individual battery cells. Isostatic pressing involves loading the battery cells into a cylinder, inserting plugs into opposite ends of the cylinder, and introducing a working medium to pressurize the cylinder, thereby densifying the battery cells inside. When the plugs are inserted into the cylinder, the high pressure generated inside the cylinder exerts a reverse force on the plugs, resulting in a significant force on the drive mechanism that moves the plugs. When the force exerted on the plugs by the high-pressure environment inside the cylinder exceeds the driving force applied by the drive mechanism, the plugs will be pushed out of the cylinder, causing them to fail and affecting the isostatic pressing effect of the equipment.

[0054] Based on the above considerations, to address the problem of plugs in isostatic pressing equipment failing due to high internal pressure during use, an isostatic pressing device was designed. This device houses individual battery cells within an isostatic pressing chamber and is positioned within the working cavity. A first driving component moves the plug along a second direction to the opening, thus sealing the opening of the isostatic pressing chamber and introducing the working medium for isostatic pressing. Simultaneously, after the plug is inserted into the opening, a connecting member can move into the gap between the frame and the plug along the second direction. Therefore, when the internal pressure of the isostatic pressing chamber is high, if the plug tends to move out of the opening along the second direction, the connecting member can abut against the frame and support the plug, providing support and reducing the probability of the plug failing due to displacement from the opening. This improves the reliability of the isostatic pressing device.

[0055] The isostatic pressing equipment disclosed in this application can be used for the isostatic pressing process of battery cells. The battery cells (e.g., solid-state battery cells with a solid electrolyte) can be used as a power source in battery devices or in various energy storage systems that use battery cells as energy storage elements. The electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., while spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0056] For ease of explanation, the following embodiments use an isostatic pressing apparatus according to an embodiment of this application for performing an isostatic pressing process on battery cells as an example.

[0057] According to some embodiments of this application, refer to Figures 1 to 3This application provides an isostatic pressing device 1000, including a frame 100, an isostatic pressing chamber 200, and an insertion mechanism 300. A working chamber 101 is formed through the interior of the frame 100 along a first direction X. The isostatic pressing chamber 200 is disposed within the working chamber 101 and is used to accommodate individual battery cells. Openings 201 communicating with the interior are formed on opposite sides of the isostatic pressing chamber 200 along a second direction Y. The first direction X is perpendicular to the second direction Y. Insertion mechanisms 300 are provided on opposite sides of the frame 100 along the second direction Y. Each insertion mechanism 300 includes a support base 310 and a plug 3. 20. A first driving member 330 and an abutting member 340, wherein the first driving member 330 is disposed on the support base 310, and the plug 320 is disposed in the working cavity 101. The first driving member 330 is driven to connect to the plug 320. The first driving member 330 is configured to drive the plug 320 to move along the second direction Y so that the plug 320 is inserted into the opening 201. The abutting member 340 is movably disposed on the support base 310. The abutting member 340 is configured to move into the gap between the frame 100 and the plug 320 along the second direction Y when the plug 320 is inserted into the opening 201 and is supported by the plug 320 and the frame 100.

[0058] The isostatic pressing chamber 200 refers to the chamber structure used to house and perform isostatic pressing on individual battery cells. Optionally, the isostatic pressing chamber 200 may have various configurations, including but not limited to a box structure, a cylindrical structure, and a spherical structure.

[0059] Along the second direction Y, openings 201 communicating with the interior are formed on both opposite sides of the isostatic pressing chamber 200. Thus, battery cells can be inserted into the isostatic pressing chamber 200 through the openings 201, or battery cells contained inside the isostatic pressing chamber 200 can be removed from the openings 201.

[0060] For example, in some embodiments, the isostatic pressing chamber 200 can be a cylindrical structure, and openings 201 are formed at both ends of the cylindrical structure along the axial direction (i.e., the second direction Y mentioned above).

[0061] The first direction X and the second direction Y mentioned above refer to two mutually perpendicular directions. For example, in some embodiments, the first direction X can be any direction parallel to the horizontal plane, and the second direction Y can be a direction parallel to the horizontal plane and perpendicular to the first direction X, or the second direction Y can also be a direction perpendicular to the horizontal plane.

[0062] The insertion mechanism 300 refers to the mechanism used to control the plug 320 to be inserted into the corresponding opening 201, and to control the abutment 340 to move into the gap between the plug 320 and the frame 100 in the second direction Y.

[0063] The insertion mechanism 300 includes a support base 310, a plug 320, a first driving member 330, and an abutment member 340; the support base 310 is used for connecting the first driving member 330 and the abutment member 340. Optionally, the support base 310 may include, but is not limited to, structural components such as a support block, a support plate, or a support beam.

[0064] The plug 320 refers to a structure used to be inserted into the opening 201 to seal the opening 201 and to transfer the working medium. It should be understood that when the plug 320 is inserted into the opening 201, the plug 320 can seal the opening 201 and achieve a seal at the opening 201; the inner side of the plug 320 can be provided with a flow channel or valve structure for transferring the working medium. It should be understood that the aforementioned working medium refers to a high-temperature, high-pressure fluid, such as water or oil.

[0065] For example, in some embodiments, the plug 320 may include a plug mounting part and a plug body part. The plug mounting part is used for assembling the plug body part, and the plug body part is used to form an insertion and sealing effect on the opening 201. The first driving member 330 can be driven to be connected to the plug mounting part so that the plug body part can move with the plug mounting part.

[0066] Optionally, the plug body may be, but is not limited to, a cylindrical structure, a prismatic structure, etc.; for example, the plug body may be a cylindrical structure, such as two concentric columnar structures with different outer diameters, wherein the columnar structure with a smaller outer diameter is used to be inserted into the inside of the opening, and the other columnar structure with a larger outer diameter is used to connect the plug mounting part and to seal the port of the opening 201.

[0067] The first driving member 330 is driven to connect to the plug 320. The first driving member 330 is used to drive the plug 320 to move along the second direction Y. Thus, the plug 320 can move along the second direction Y under the action of the first driving member 330, for example, to the insertion sealing opening 201, or to be moved out of the opening 201.

[0068] The first driving component 330 can be directly connected to the plug 320 through its output end; or, the output end of the first driving component 330 can be indirectly connected to the plug 320 through a connecting structure (such as a connecting plate, connecting block, connecting column, etc.) or a guiding structure (such as a guide bearing, slider, etc.).

[0069] Optionally, the first driving component 330 may include, but is not limited to, a driving source such as a cylinder or a hydraulic cylinder. The number of the first driving components 330 may be one or more, and one or more driving components may be used to synchronously drive the plug 320 to achieve the movement of the plug 320.

[0070] The first driving component 330 is disposed on the support base 310; optionally, the first driving component 330 can be fixedly installed on the support base 310 by means of fastener fastening, snap-fitting, welding, bonding or other methods.

[0071] The plug 320 is disposed in the working chamber 101 and is connected to the output end of the first drive member 330; thus, when the isostatic pressing chamber 200 is disposed in the working chamber 101, the first drive member 330 can be used to control the plug 320 to move along the second direction Y to be inserted into the opening 201 of the isostatic pressing chamber 200.

[0072] Optionally, the isostatic pressing chamber 200 described above is disposed in the working chamber 101, and can be moved into the working chamber 101 or moved out of the working chamber 101 by means of, but not limited to, manual handling, transmission by a transmission mechanism (conveyor belt, conveyor roller) or gripping by a gripping mechanism (such as a gripper, a robot arm, etc.).

[0073] The abutment 340 refers to a structural component used to support the plug 320 in the gap between the plug 320 and the frame 100 along the second direction Y when the plug 320 is inserted into the opening 201 of the isostatic pressing chamber 200. Optionally, the abutment 340 may be, but is not limited to, a support block, a support plate, a support beam, a support pad, or other structural components.

[0074] For example, in some embodiments, the abutment 340 may be a pad structure, which provides support for the plug 320 and the frame 100 by utilizing the corresponding end side of the pad structure.

[0075] The abutment 340 is movably disposed on the support base 310; alternatively, the abutment 340 may be slidably disposed on the support base 310, or the abutment 340 may be indirectly movably disposed on the support base 310 via an intermediate structure (such as the floating member 350 described below). In this way, the abutment 340 can move relative to the support base 310 so that when the plug 320 is inserted into the opening 201, the abutment 340 can move into the gap between the frame 100 and the plug 320 along the second direction Y to form a supporting function.

[0076] Optionally, the abutment 340 can be moved manually; or the abutment 340 can be driven to move by a drive source such as a cylinder, hydraulic cylinder, or motor.

[0077] It should be understood that when the plug 320 is inserted into the opening 201 and the working medium is introduced into the isostatic pressing chamber 200 through the plug 320 for isostatic pressing operation, a high-pressure state will be formed inside the isostatic pressing chamber 200. This internal pressure will exert a reverse force on the plug 320. When the reverse force exerted on the plug 320 by the inside of the isostatic pressing chamber 200 is greater than the force exerted on the plug 320 by the first driving member 330, the plug 320 may move outwards from the opening 201 along the second direction Y. When the plug 320 moves a certain distance outward from the opening 201 along the second direction Y, it abuts against the abutment 340. (Since the abutment 340 can move relative to the support 310 between the plug 320 and the frame 100, the abutment 340 will form a certain gap with the plug 320 and the frame 100 when it is between the plug 320 and the frame 100. Therefore, the plug 320 will form a certain displacement and abut against the frame after acting on the abutment. This allows the abutment 340 to transfer the force inside the isostatic pressure treatment chamber 200 on the plug 320 to the frame 100. That is, the abutment 340 can support the plug 320 and thus prevent the plug 320 from moving outward from the opening 201.)

[0078] Here, frame 100 refers to the component used to provide support; for example, the abutment 340 moves into the gap between the plug 320 inserted in the opening 201 and the frame 100 along the second direction Y, and the frame 100 is used to support the abutment 340 so that the force of the plug 320 on the abutment 340 is transmitted to the frame 100 through the abutment 340.

[0079] Optionally, the frame 100 can be in any configuration. The interior of the frame 100 is provided with a working chamber 101 through the first direction X, so that the isostatic pressing chamber 200 can be fed into the working chamber 101 along the first direction X, and the plug 320 and the movable abutment 340 can be inserted to facilitate the subsequent isostatic pressing operation.

[0080] For example, in some embodiments, the frame 100 may be in the form of a ring structure, with a working cavity 101 formed around the inside of the ring structure frame 100.

[0081] The isostatic pressing device 1000 provided in this application embodiment has an isostatic pressing chamber 200 disposed in the working cavity 101 of a frame 100. The first driving member 330 of the insertion mechanism 300 at opposite ends of the frame 100 drives the plug 320 to move along the second direction Y until it is inserted into the opening 201. This allows the plug 320 to seal the opening 201 of the isostatic pressing chamber 200 and provide a working medium into the opening 201 to achieve the isostatic pressing operation. Simultaneously, when the plug 320 is inserted into the opening 201, it can also... When the abutment 340 is moved into the gap between the frame 100 and the plug 320 along the second direction Y, and the force exerted on the plug 320 by the high pressure environment inside the isostatic pressing chamber 200 is greater than the driving force applied by the first driving member 330, so that the plug 320 tends to move out of the opening 201, the abutment 340 can abut against the frame 100 and support the plug 320, thereby reducing the probability of the plug 320 moving out of the opening 201 and causing failure, and thus improving the reliability of the isostatic pressing equipment 1000.

[0082] Please refer to Figures 1 to 3 In some embodiments, the insertion mechanism 300 further includes a floating member 350, which is movably disposed on the support base 310 along the second direction Y; the abutment member 340 is movably disposed on the floating member 350.

[0083] The floating member 350 refers to a structural member that is used for the connection of the abutment member 340 and is movable relative to the support 310 in the second direction Y.

[0084] Optionally, the floating component 350 may include, but is not limited to, various configurations such as plate structure, block structure, rod structure, and beam structure. The floating component 350 may be slidably connected to the support base 310 along the second direction Y; or, an intermediate structure (such as a connecting plate, guide column, slide rail, or other structural component) may be provided on the support base 310, and the floating component 350 may be movably connected to the intermediate structure along the second direction Y, thereby realizing the movable setting of the floating component 350 relative to the support base 310 along the second direction Y.

[0085] The abutment 340 is movably mounted on the floating member 350. Optionally, the abutment 340 can be slidably mounted on the floating member 350 via a guide rail, a slide groove, or other structure. Alternatively, a drive source such as a cylinder or a hydraulic cylinder can be mounted on the abutment 340, and the output end of the drive source can be connected to the abutment 340 to realize the movement of the abutment 340 relative to the floating member 350.

[0086] Optionally, the abutment 340 can move relative to the floating member 350 and along any trajectory, such as moving along a straight trajectory, for example, moving along a first direction X to move into or out of the working cavity 101; or moving along a curved trajectory, for example, rotating about a second direction Y to rotate into or out of the working cavity 101.

[0087] It should be understood that since the abutment 340 can move relative to the support 310 into the gap between the plug 320 and the frame 100 along the second direction Y, when the abutment 340 is located in the gap between the plug 320 and the frame 100 along the second direction Y, the opposite ends of the abutment 340 will form a certain gap with the plug 320 and the frame 100 respectively.

[0088] When the abutment 340 is used to support the plug 320 and the frame 100, the plug 320 will move a certain distance along the second direction Y and then abut against the abutment 340. Then the abutment 340 will push against the frame 100 along the second direction Y until the abutment 340 abuts against and supports the frame 100.

[0089] With this configuration, by placing the abutment 340 on the floating member 350 and allowing the floating member 350 to move movably along the second direction Y on the support base 310, the floating member 350 can move synchronously with the abutment 340 along the second direction Y. This can effectively reduce the probability of the abutment 340 undergoing rigid deformation or dry friction-type relative slippage along the second direction Y, thereby effectively improving the reliability of the abutment 340 and reducing the probability of damage to the abutment 340.

[0090] Please refer to Figures 1 to 3 as well as Figure 6 In some embodiments, the insertion mechanism 300 further includes a second drive member 360, which is disposed on the floating member 350 and the output end of the second drive member 360 is connected to the abutment member 340. When the plug 320 is inserted into the opening 201, the second drive member 360 is configured to drive the abutment member 340 to move into the gap between the frame 100 and the plug 320 along the second direction Y.

[0091] The second driving component 360 refers to the component used to drive and move the abutment component 340.

[0092] Optionally, the second driving member 360 includes, but is not limited to, driving components such as a driving cylinder, a driving hydraulic cylinder, and a driving motor. The output end of the second driving member 360 is connected to the abutment member 340. In this way, the second driving member 360 can drive the abutment member 340 to move relative to the floating member 350 through the output action of the output end.

[0093] For example, when the second driving member 360 is a driving cylinder or a driving hydraulic cylinder, the output direction of the piston of the driving cylinder or the driving hydraulic cylinder can be set parallel to the first direction X, so that the abutment member 340 can slide relative to the floating member 350 along the first direction X; or, when the second driving member 360 is a driving motor, the output end of the driving motor can be converted into movement along the first direction X through a gear and rack transmission structure or a gear and belt transmission structure, so as to realize the action of driving the abutment member 340 to slide relative to the floating member 350 along the first direction X.

[0094] With this configuration, the abutment 340 can be moved by the second drive member 360 located on the floating member 350, so that the abutment 340 can slide into the gap between the frame 100 and the plug 320 along the second direction Y under the action of the second drive member 360.

[0095] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments, the output direction of the second drive 360 ​​is parallel to the first direction X.

[0096] In this embodiment, the output direction of the second driving member 360 can be set to be parallel to the first direction X. In this way, the second driving member 360 can drive the abutment member 340 to move along the first direction X.

[0097] For example, in some embodiments, a groove extending along the first direction X can be provided on the floating member 350, and a slider that slides in cooperation with the groove can be provided on the abutting member 340. In this way, the abutting member 340 can slide along the first direction X in the groove of the floating member 350 by the slider under the driving action of the second driving member 360.

[0098] Alternatively, in some other embodiments, a slide rail extending along the first direction X can be provided on the floating member 350, and a slider cooperating with the slide rail can be provided on the abutting member 340. In this way, the abutting member 340 can slide along the slide rail along the first direction X under the driving action of the second driving member 360.

[0099] It should be understood that, since the first driving member 330 controls the movement direction of the plug 320 toward the second direction Y, the abutment member 340 needs to avoid the movement direction of the plug 320 in order to reduce the impact of the plug 320 moving along the second direction Y.

[0100] In this embodiment, by setting the output direction of the second driving member 360 to be parallel to the first direction X, the abutment member 340 can move relative to the floating member 350 along the first direction X under the driving action of the second driving member 360; and the first direction X is perpendicular to the second direction Y, so the moving direction of the abutment member 340 is perpendicular to the moving direction of the plug 320, and the abutment member 340 has a low impact on the moving path of the plug 320.

[0101] Please refer to Figure 3 , Figure 5 and Figure 6 In some embodiments, the insertion mechanism 300 further includes an elastic limiting member 370, with its opposite ends acting on the floating member 350 and the support base 310 along the second direction Y.

[0102] Among them, the elastic limiting component 370 refers to a structural component with elastic recovery capability.

[0103] Optionally, the elastic limiting component 370 includes, but is not limited to, components such as springs, elastic washers, and elastic buffer blocks. The number of elastic limiting components 370 can be one or more.

[0104] One end of the elastic limiting member 370 can be fixedly connected to the floating member 350, or one end of the elastic limiting member 370 can abut against the floating member 350 without forming a connection. Similarly, the other end of the elastic limiting member 370 can be fixedly connected to the support base 310, or the other end of the elastic limiting member 370 can abut against the support base 310 without forming a connection.

[0105] It should be understood that when the abutment 340 moves relative to the floating member 350 along the first direction X into the gap between the plug 320 and the frame 100 along the second direction Y, and the plug 320 tends to move out of the opening 201 along the second direction Y under the pressure inside the isostatic pressure treatment chamber 200, the plug 320 can move along the second direction Y to abut against the abutment 340, causing the abutment 340 to move to abut against the frame 100. At this time, the floating member 350 can move synchronously with the abutment 340 along the second direction Y and squeeze the elastic limiting member 37. 0. Thus, the elastic limiting member 370 can achieve the elastic limiting and buffering effect; and when the plug 320 moves back into the opening 201 and no longer abuts against the abutting member 340, the floating member 350 can move back along the second direction Y under the action of the elastic limiting member 370, so that the abutting member 340 moves back synchronously with the floating member 350 and re-forms a certain gap with the frame 100. When the abutting member 340 is subsequently moved out along the first direction X, the probability of the abutting member 340 contacting the frame 100 and affecting the movement of the abutting member 340 can be effectively reduced.

[0106] Please refer to Figures 4 to 7 In some embodiments, the elastic limiting member 370 includes a connecting post 371 and an elastic part 372. The surface of the connecting post 371 is provided with an abutting protrusion 3711. One end of the connecting post 371 along the second direction Y is fitted with the elastic part 372 so that the elastic part 372 abuts against the abutting protrusion 3711. The floating member 350 is also provided with a through hole 350a. One end of the connecting post 371 fitted with the elastic part 372 passes through the through hole 350a so that the elastic part 372 abuts against the floating member 350. The other end of the connecting post 371 abuts against the support base 310.

[0107] The surface of the connecting post 371 is also provided with an abutting protrusion 3711, so that when the elastic part 372 is sleeved from one end of the connecting post 371 along the second direction Y onto the connecting post 371, one end of the elastic part 372 can abut against the abutting protrusion 3711.

[0108] Optionally, the abutting protrusion 3711 can be a continuous protruding ring structure protruding from the surface of the connecting post 371; or, the abutting protrusion 3711 can also be a non-continuous multi-protrusion structure protruding from the surface of the connecting post 371, with the multi-protrusion structure arranged around the circumference of the connecting post 371, and the multi-protrusion structure is used together to abut one end of the supporting elastic part 372.

[0109] The other end of the connecting post 371 relative to the sleeved elastic part 372 is used to abut against the support base 310; optionally, the connecting post 371 can be connected to the support base 310 by means of threaded connection, snap-fit, plug-in connection, fastener connection, etc.; or, the connecting post 371 can not be connected to the support base 310, and when the floating member 350 moves toward the support base 310, the connecting post 371 can move synchronously with the floating member 350 to abut against the support base 310.

[0110] The floating member 350 has a through hole 350a, and one end of the connecting post 371 with the elastic part 372 passes through the through hole 350a. When the floating member 350 moves relative to the support base 310 along the second direction Y, the connecting post 371 can pass through the through hole 350a and move relative to the floating member 350. The two opposite ends of the elastic part 372 on the connecting post 371 abut against the abutting protrusion 3711 and the floating member 350 respectively to form compression to realize the elastic fiber.

[0111] With this configuration, when the floating member 350 moves synchronously with the abutment member 340 towards the support base 310 along the second direction Y, the floating member 350 can form a relative displacement with respect to the connecting column 371 and along the second direction Y, so that the floating member 350 squeezes the elastic part 372 and compresses the elastic part 372; when the abutment member 340 loses its force, the elastic part 372 can push against the floating member 350 according to its own elastic restoring force, so that the floating member 350 and the abutment member 340 move synchronously to their original positions along the second direction Y.

[0112] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, a channel 341 is provided on at least one side surface of the abutment member 340 along the second direction Y, and the channel 341 communicates to the outside of the abutment member 340 in a direction perpendicular to the second direction Y.

[0113] The groove 341 refers to a groove structure formed on at least one side surface of the abutment member 340 along the second direction Y. Optionally, the groove 341 can be provided on the side surface of the abutment member 340 along the second direction Y and facing the plug 320, or the groove 341 can be provided on the side surface of the abutment member 340 along the second direction Y and facing the support 310, or the groove 341 can be provided on both opposite sides surface of the abutment member 340 along the second direction Y.

[0114] The number of channels 341 provided on any side surface of the abutment member 340 along the second direction Y can be one, two, or more than one.

[0115] The extension direction of the channel 341 can be arbitrarily set. For example, the channel 341 can extend in a straight line along a direction parallel to the first direction X, or the channel 341 can extend in a straight line along a direction intersecting the first direction X, or the channel 341 can extend along a curve.

[0116] The channel 341 connects to the outside of the abutment 340 along a direction perpendicular to the second direction Y. Thus, when the surface of the abutment 340 along the second direction Y is used to abut and support the plug 320 or the frame 100, the channel 341 can connect the surface of the abutment 340 used to abut and support the plug 320 or the frame 100 with the outside, thereby effectively reducing the probability that the abutment 340 will adhere and adhere to the plug 320 or the frame 100 due to the large force it is subjected to when it is supported (similar to the principle of a suction cup, which is prone to sticking under the action of supporting force).

[0117] Optionally, in some embodiments, a coating, such as a molybdenum disulfide coating, can be provided on at least one surface of the abutment 340 along the second direction Y. Taking a molybdenum disulfide coating as an example, a hard and wear-resistant molybdenum disulfide coating can be formed by providing a molybdenum disulfide coating on at least one surface of the abutment 340 along the second direction Y and forming the coating through methods such as chemical vapor deposition, thereby creating a rough surface on the support surface of the abutment 340. When the abutment 340 is used to abut against and support the plug 320 or the frame 100, the rough surface formed by the molybdenum disulfide coating can effectively reduce the probability of adhesion between the abutment 340 and the supported plug 320 or frame 100.

[0118] Please refer to Figure 3 and Figure 4 In some embodiments, the insertion mechanism 300 further includes a guide structure 380, which includes a guide portion 381 and a sliding portion 382. The guide portion 381 is connected to the support base 310, and the sliding portion 382 is slidably disposed on the guide portion 381 along the second direction Y. The sliding portion 382 is connected to the plug 320.

[0119] The guide structure 380 is used to guide the movement of the plug 320 along the second direction Y. Optionally, the number of guide structures 380 can be one or more, and one or more guide structures 380 can be used simultaneously to guide the movement of the plug 320.

[0120] The guide structure 380 includes a guide portion 381 and a sliding portion 382. The guide portion 381 is a component that is set on the support base 310 and forms a guiding effect along the second direction Y. The sliding portion 382 is a component that moves synchronously with the plug 320 and slides relative to the guide portion 381 along the second direction Y.

[0121] Optionally, the guide portion 381 may be, but is not limited to, a groove or slide rail formed on the support base 310, or a guide cylinder or bearing housing fixedly mounted on the support base 310. Correspondingly, the sliding portion 382 may be, but is not limited to, a sliding rod or a guide shaft.

[0122] For example, in some embodiments, the guide portion 381 can be a bearing seat, and the sliding portion 382 can be a guide shaft. Along the second direction Y, two coaxially arranged bearing seats are arranged sequentially at intervals on the support base 310. The guide shaft passes through the two bearing seats and slides with the two bearing seats. One end of the guide shaft is connected to the plug 320, and the output end of the first drive member 330 can be connected to the opposite end of the guide shaft. The first drive member 330 controls the guide shaft to slide relative to the bearing seat along the second direction Y, so that the plug 320 can move synchronously along the second direction Y under the action of the guide shaft.

[0123] With this configuration, the sliding part 382 and the guide part 381 form a sliding fit along the second direction Y to guide the movement of the plug 320, thereby improving the stability of the movement of the plug 320.

[0124] Please refer to Figure 3 and Figure 4 In some embodiments, the floating member 350 is movably disposed on the sliding portion 382 along the second direction Y.

[0125] In this embodiment, the floating member 350 can also be movably disposed on the sliding part 382 along the second direction Y.

[0126] Optionally, the floating component 350 can be slidably connected to the sliding part 382 via a slide rail, slide groove or other structure; or, a sliding hole, sliding sleeve seat or other structure can be provided on the floating component 350 for the sliding part 382 to slide through.

[0127] With this configuration, the floating member 350 can move relative to the sliding part 382 along the second direction Y, thereby achieving floating adjustment of the floating member 350 and the abutment member 340 in the second direction Y. Meanwhile, the sliding part 382 can simultaneously guide the movement of the plug 320, thus effectively improving the assembly compactness of the floating member 350 and the guide structure 380.

[0128] Please refer to Figures 3 to 6 In some embodiments, the floating member 350 is provided with a mounting part 3501, and the mounting part 3501 and the sliding part 382 slide in cooperation along the second direction Y.

[0129] Understandably, the mounting part 3501 refers to a component used to form a sliding fit with the sliding part 382. Optionally, the mounting part 3501 includes, but is not limited to, structures such as sliding blocks, slide grooves, slide rails, and sliding sleeve seats.

[0130] For example, in some embodiments, the mounting part 3501 may be a sliding sleeve, which refers to a part used to support, position and guide the movement of the sliding part 382; the sliding sleeve is used to allow the sliding part 382 to slide freely and stably in its inner cavity.

[0131] Optionally, a through hole can be provided on the floating member 350 for assembling the sliding sleeve seat. The number of sliding sleeve seats can be, but is not limited to, one, two, or more than two, and the specific number of sliding sleeve seats can be consistent with the number of sliding parts 382.

[0132] In some embodiments, when the guide portion 381 and the sliding portion 382 of the guide structure 380 are respectively a linear bearing and a guide shaft, the linear bearing can be mounted on the support base 310, and the guide shaft is slidably inserted into the inner cavity of the linear bearing, so that the guide shaft can slide relative to the linear bearing and along the second direction Y to achieve the guiding function; wherein, the floating member 350 can be a plate-shaped floating plate, the thickness direction of the floating plate is oriented towards the second direction Y, and a sliding sleeve seat is provided on the floating plate along the thickness direction (that is, the second direction Y), and the floating plate can be sleeved on the guide shaft through the sliding sleeve seat.

[0133] With this configuration, the mounting part 3501 and the sliding part 382 form a sliding fit along the second direction Y. When the abutment 340 is used to support between the plug 320 and the frame 100, the abutment 340 can slide and adjust synchronously with the floating part 350 on the sliding part 382.

[0134] Please refer to Figure 3 and Figure 4 In some embodiments, the output end of the first drive member 330 is connected to the sliding part 382.

[0135] In this embodiment, the output end of the first driving member 330 can be connected to the sliding part 382, ​​so that the first driving member 330 can drive the sliding part 382 to slide relative to the guide part 381 along the second direction Y, and then drive the plug 320 through the sliding part 382 to achieve guiding sliding.

[0136] Optionally, the first driving member 330 may be connected to the sliding part 382 through a connecting structure such as a connecting block, connecting rod, or connecting plate.

[0137] For example, in some embodiments, the first driving member 330 may be a driving cylinder, the output end of the driving cylinder is arranged facing the second direction Y, and the output end of the driving cylinder can be connected to the sliding part 382 through a connecting block, so that the sliding part 382 can move synchronously with the output end of the driving cylinder.

[0138] Optionally, when multiple guide structures 380 are provided on each support surface, such as two guide structures 380, the guide portions 381 of the two guide structures 380 can be provided on the guide surface at intervals along a direction perpendicular to the second direction Y, and the first driving member 330 is located between the two guide portions 381; a long strip-shaped connecting block can be used to simultaneously connect the output end of the first driving member 330 and the same side end of the two sliding portions 382, ​​such as... Figure 4 As shown, the first driving member 330 can be used to synchronously drive the two sliding parts 382 to move in a guiding manner, thereby causing the plug 320 to move in a guiding manner under the action of the sliding parts 382.

[0139] With this configuration, the first driving component 330 can control the sliding part 382 to slide according to the guiding action of the guide part 381, thereby making the sliding part 382 drive the plug 320 to move more stably.

[0140] Please refer to Figure 3 and Figure 4 In some embodiments, the support base 310 includes a plurality of support surfaces 3101 that are spaced apart and parallel to each other. Each of the plurality of support surfaces 3101 is provided with a first driving member 330 and a guide portion 381 of a guide structure 380. Furthermore, the output end of the first driving member 330 is connected to a sliding portion 382 of the guide structure 380 provided on the same support surface 3101.

[0141] Understandably, the support surface 3101 refers to the surface of the support base 310 used to install the guide part 381.

[0142] The number of support surfaces 3101 can be multiple, such as two, three or more, and the multiple support surfaces 3101 are arranged in parallel.

[0143] For example, the support base 310 may be a block structure, so that the two opposing surfaces of the support base 310 can form mutually parallel support surfaces 3101; or, the support base 310 may include multiple vertical plate structures, so that any one side surface of the multiple vertical plate structures can form the support surface 3101.

[0144] With this configuration, by providing guide portions 381 on multiple support surfaces 3101, and using the sliding portions 382 corresponding to the multiple guide portions 381 to act simultaneously on the plug 320, the movement of the plug 320 along the second direction Y can be made more stable. At the same time, when the floating member 350 passes through multiple sliding sleeves on the multiple sliding portions 382 corresponding to the multiple guide portions 381, the floating member 350 is also more stable, thereby making the sliding adjustment process of the floating member 350 relative to the sliding portion 382 along the second direction Y more stable.

[0145] Please refer to Figure 3 and Figure 4 In some embodiments, the support base 310 includes a support bottom 311 and two support connecting portions 312 spaced apart on the support bottom 311 along a first direction X; along the first direction X, the side surface of the two support connecting portions 312 facing away from each other is a support surface 3101; along the second direction Y, the opposite sides of the frame 100 are respectively inserted between the two support connecting portions 312 of the support base 310 on the corresponding side.

[0146] In this embodiment, the support base 310 includes a support bottom 311 and a support connection portion 312; wherein, the support bottom 311 refers to a support structure used to support a surface placed on a reference surface (such as the ground, a workbench, etc.).

[0147] Optionally, the support base 311 may include, but is not limited to, structural components such as support plates, support blocks, and support platforms.

[0148] The support connection part 312 refers to the structural component provided on the support bottom 311 and used for connecting and assembling the guide part 381 and the first drive member 330.

[0149] Optionally, the support connection 312 may be fixedly connected to the support bottom 311 by means of welding, fastener fastening, or other methods. The support connection 312 may be, but is not limited to, structural components such as a support plate, support column, support block, or support beam.

[0150] For example, in some embodiments, the support bottom 311 may be a support base plate, and the support connection part 312 may be a support upright plate. There are two support upright plates, which are fixed to the support bottom 311 by welding or bolting. The two support upright plates are arranged parallel to each other along the first direction X. Optionally, reinforcing ribs may be provided between the support upright plates and the support base plate on opposite sides along the first direction X to further enhance the strength of the support upright plates.

[0151] The frame 100 can be inserted into the two support connection portions 312 of the corresponding support base 310 at opposite ends along the second direction Y. In this way, the gap between the two support connection portions 312 can be used to avoid the frame 100, so that the support base 310 and the frame 100 are relatively independently set. When the abutment member 340 is used to abut against the frame 100 and support the plug 320, if the force transmitted by the abutment member 340 to the frame 100 is too large, it will cause the frame 100 to deform to a certain extent. Since the frame 100 and the support base 310 are not connected, the deformation of the frame 100 has a low impact on the first driving member 330 set on the support base 310 and the plug 320 connected to the first driving member 330, so that the concentricity of the plug 320 when inserted into the opening 201 is also less affected.

[0152] Meanwhile, the side surface of the two support connection parts 312 facing away from each other is the support surface 3101, that is, the support surface 3101 and the frame 100 are not in the same spatial range; when the support surface 3101 is used to set the installation guide part 381 and the first driving member 330, the frame 100 has a low impact on the installation operation of the guide part 381 and the first driving member 330, and the probability of interference between the frame 100 and the guide part 381 and the first driving member 330 is low.

[0153] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the support base 310 further includes at least three equal-height columns 313, each equal-height column 313 being disposed parallel to the first direction X between two support connection portions 312, and the opposite ends of the equal-height columns 313 being connected to the support connection portions 312 on the corresponding sides.

[0154] The equal-height column 313 refers to the connection structure used to simultaneously connect two spaced-apart support connection parts 312. Optionally, the equal-height column 313 may be, but is not limited to, a cylindrical, prismatic, or other similar mounting column; the opposite ends of the equal-height column 313 may be, but is not limited to, connected to the support connection parts 312 on opposite sides by means of welding, fastener fastening, snap-fitting, threaded connection, or other methods.

[0155] The number of equal height columns 313 can be three or more; multiple equal height columns 313 can be set at any point between two support connection parts 312.

[0156] For example, in some embodiments, taking three equal-height columns 313 as an example, the three equal-height columns 313 can be respectively set at different locations between the two support connection parts 312, and the three equal-height columns 313 are respectively connected to the two support connection parts 312 in an attitude parallel to the first direction X. In this way, the parallelism between the two support connection parts 312 can be effectively improved.

[0157] It should be understood that when setting the contour column 313, the specific position of the frame 100 between the two support connection parts 312 can be referenced, so that the contour column 313 can avoid the setting position of the frame 100, thereby reducing the probability of interference between the contour column 313 and the frame 100.

[0158] With this configuration, by setting at least three equal-height columns 313 between and connecting the two support connection portions 312 in a manner parallel to the first direction X, the parallelism of the support surfaces 3101 of the two support connection portions 312 is effectively guaranteed. As a result, when the guide structures 380 respectively provided on the support surfaces 3101 of the two support connection portions 312 are used to guide the plug 320, the guiding effect is better, thereby making the movement of the plug 320 more stable.

[0159] The isostatic pressing device 1000 provided in this application will now be described in detail according to specific embodiments.

[0160] Please refer to Figures 1 to 7In some embodiments, the isostatic pressing device 1000 includes a frame 100, an isostatic pressing chamber 200, and an insertion mechanism 300. A working cavity 101 is provided through the interior of the frame 100 along a first direction X; an insertion mechanism 300 is provided on both opposite sides of the frame 100 along a second direction Y, wherein the first direction X is perpendicular to the second direction Y.

[0161] Along the second direction Y, openings 201 connecting the interior are formed on both opposite sides of the isostatic pressing chamber 200.

[0162] The insertion mechanism 300 includes a support base 310, a guide structure 380, a plug 320, a first driving member 330, a second driving member 360, a floating member 350, an elastic limiting member 370, and an abutment member 340.

[0163] The support base 310 includes a support bottom 311 and two support connecting portions 312 spaced apart along the first direction X on the support bottom 311. In this embodiment, the support connecting portions 312 can be support uprights. Along the first direction X, the side surface of the two support connecting portions 312 facing away from each other is the support surface 3101.

[0164] The guide structure 380 includes a guide portion 381 and a sliding portion 382. In this embodiment, the guide portion 381 can be a bearing housing, and the sliding portion 382 can be a guide shaft. Each of the two support connecting portions 312 of the support base 310 is provided with two sets of guide structures 380, and the bearing housings of the two sets of guide structures 380 can be spaced apart on the support surface 3101 along the direction of gravity. Thus, one end of the guide shaft of the two sets of guide structures 380 is used to connect to the plug 320.

[0165] Meanwhile, each support surface 3101 is provided with a first driving member 330; in this embodiment, the first driving member 330 can be a driving cylinder. The output end of the first driving member 330 is simultaneously connected to the guide shafts of two sets of guide structures 380 provided on the same support surface 3101 via a connecting block. The first driving member 330 drives the guide shaft to move along the second direction Y, so that the guide shaft drives the plug 320 to move along the second direction Y and insert it into the opening 201 to seal the opening 201.

[0166] In this embodiment, the floating member 350 can be a floating plate, and a sliding sleeve seat is installed on the floating plate. The floating member 350 is slidably disposed on the sliding part 382 along the second direction Y by passing the guide shaft through the sliding sleeve seat.

[0167] The elastic limiting member 370 includes a connecting post 371 and an elastic part 372. The surface of the connecting post 371 is provided with an abutting protrusion 3711. One end of the connecting post 371 along the second direction Y is fitted with the elastic part 372 so that the elastic part 372 abuts against the abutting protrusion 3711. The floating member 350 is also provided with a through hole 350a. One end of the connecting post 371 with the elastic part 372 passes through the through hole 350a so that the elastic part 372 abuts against the floating member 350. The other end of the connecting post 371 abuts against the support base 310.

[0168] The second driving component 360 can be a driving cylinder, and it is mounted on the floating component 350. The abutment component 340 can be a pad structure, which can be slidably mounted on the floating component 350 along the first direction X via a slide rail. By connecting the output end of the second driving component 360 to the pad structure, the movement of the pad structure relative to the floating component 350 along the first direction X can be controlled.

[0169] Thus, when the plug 320 is inserted and sealed in the opening 201, the second driving member 360 can drive the pad structure to move into the gap between the frame 100 and the plug 320 along the second direction Y. The pad structure supports the plug 320 and the frame 100 along the second direction Y, which can effectively reduce the probability that the plug 320 will move out of the opening 201 due to the large internal pressure of the isostatic pressing chamber 200, thereby improving the reliability of the isostatic pressing equipment 1000.

[0170] Furthermore, when the floating member 350 moves synchronously with the abutment member 340 towards the support base 310 along the second direction Y, the floating member 350 can form a relative displacement with respect to the connecting column 371 along the second direction Y, so that the floating member 350 squeezes and compresses the elastic part 372; when the abutment member 340 loses the force applied by the plug 320 (for example, after the isostatic pressing process is completed, the isostatic pressing chamber 200 is depressurized), the elastic part 372 can push against the floating member 350 according to its own elastic restoring force, so that the floating member 350 and the abutment member 340 move synchronously to their original positions along the second direction Y. This facilitates the subsequent operation of the second driving member 360 driving the abutment member 340 to move along the first direction X.

[0171] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
