Description

Technical Field

[0001] This utility model relates to the field of six-sided top press technology, specifically a guide sleeve for a six-sided top press. Background Technology

[0002] The six-sided hydraulic press is a key piece of equipment used for synthesizing superhard materials such as diamond and cubic boron nitride. It has six working cylinders and can achieve a single-stage pressure of 6-8 GPa.

[0003] The guide sleeve ensures that the piston of the six-sided press maintains the accurate position and orientation during its movement, enabling the piston to reciprocate along a predetermined trajectory. This guarantees the accuracy and stability of the pressing process, thereby ensuring that the superhard material is in a stable and correct position during processing and preventing the material from shifting or deforming during the pressing process.

[0004] The existing patent document, authorized by announcement number CN220990720U, describes a guide sleeve for a six-sided top press, comprising a guide sleeve, an inner protective sleeve, a rubber ring on the outer circumference of the protective sleeve, a support plate inside the rubber ring, and symmetrical rubber rings on the inner wall of the rubber ring. This technical solution involves embedding a locking block into a slot, simultaneously embedding an installation block into the side wall of the guide sleeve, and embedding a fixing block into the guide sleeve under the action of a spring. This makes the installation of the protective sleeve and the guide sleeve more convenient, and facilitates the disassembly and replacement of the protective sleeve. However, when using the installation block and fixing block for connection, the subsequent disassembly of the guide sleeve and the protective sleeve becomes cumbersome. Furthermore, the inability to form a bidirectional locking mechanism between the guide sleeve and the protective sleeve reduces the stability of the connection between the protective sleeve and the guide sleeve. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a six-sided top press guide sleeve, which solves the problem that when using mounting blocks and fixing blocks for connection, the subsequent disassembly of the guide sleeve and protective sleeve is cumbersome, and the inability to form a bidirectional interlocking between the guide sleeve and protective sleeve reduces the stability of the connection between the protective sleeve and the guide sleeve. When the interlocking slider meets the relief groove, the external thread and the internal thread are disconnected, pushing the protective sleeve to continue sliding into the guide sleeve, embedding the interlocking slider into the relief groove, and at the same time, the convex strip is embedded into the interlocking groove. Through the bidirectional interlocking formed, the stability of the connection between the protective sleeve and the guide sleeve is ensured.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a guide sleeve for a six-sided top press, comprising a protective component and a guide sleeve assembly. The protective component includes a protective sleeve, and the guide sleeve assembly includes a guide sleeve and a sealing ring. A rubber ring is connected to the outer wall of one end of the protective sleeve, and a snap-fit ​​slider is connected to the outer wall of the protective sleeve. An external thread is formed on the outer wall of the protective sleeve on the side away from the rubber ring. An inner groove is formed on the inner side of the rubber ring. A positioning outer tube and a positioning inner tube are symmetrically connected to the inner wall of the inner groove. A shock-absorbing spring is connected to the inner side of the positioning inner tube, and a rubber head is connected to one end of the shock-absorbing spring. A limit ring groove is formed on the inner wall of the guide sleeve, and a clearance groove is formed on the inner wall of the guide sleeve. A convex strip integrally formed with the guide sleeve is provided on the inner wall of the clearance groove. An installation ring is connected to the outer wall of one end of the guide sleeve.

[0007] The beneficial effects of this utility model are as follows: When assembling the protective sleeve and the guide sleeve, they are first connected by the mutual cooperation of the external thread and the internal thread. When the locking slider meets the relief groove, the external thread and the internal thread are disconnected, pushing the protective sleeve to continue sliding into the guide sleeve, embedding the locking slider into the relief groove. At the same time, the convex strip is embedded into the locking groove, and the bidirectional locking is formed to ensure the stability of the connection between the protective sleeve and the guide sleeve.

[0008] The groove is designed to position the inner tube and the rubber head for sliding via the outer tube groove.

[0009] As a further improvement to the above technical solution: the positioning outer tube is installed in a ring at equal intervals on the inner wall of the inner groove, and an outer tube sliding groove is opened on the inner side of the positioning outer tube.

[0010] The beneficial effects of this improvement are: the outer tube groove is used to position the insertion of the inner tube and the rubber head, and the outer tube groove is used to position the groove for the sliding of the inner tube and the rubber head.

[0011] To dampen the impact force during deformation:

[0012] As a further improvement to the above technical solution: the end of the positioning inner tube away from the inner wall of the inner ring groove is inserted into the outer tube groove, and the rubber head is connected to the shock-absorbing spring through an interference fit, thereby slidingly connecting with the positioning inner tube.

[0013] The beneficial effects of this improvement are as follows: when the rubber ring is squeezed, the outer positioning tube slides and touches the rubber head. When the rubber head slides, it squeezes the damping spring. The damping spring is used to buffer the impact force during the deformation process. When the inner positioning tube slides, it drives the rubber head to move. When the rubber head touches the inner wall of the outer tube groove, the damping spring is also used to buffer the impact force through deformation.

[0014] For connection with internal threads, thereby enabling the assembly connection of the protective sleeve and the guide sleeve:

[0015] As a further improvement to the above technical solution: there are four snap-fit ​​sliders, which are installed on the outer wall of the protective sleeve at equal intervals of 90°.

[0016] The beneficial effects of this improvement are: by setting up a snap-fit ​​slider, it is used to connect with the internal thread, thereby realizing the assembly connection between the protective sleeve and the guide sleeve.

[0017] To ensure the stability of the connection between the protective sleeve and the guide sleeve when the convex strip is inserted into the snap-fit ​​groove:

[0018] As a further improvement to the above technical solution: a snap-fit ​​groove is provided on the side of the snap-fit ​​slider away from the protective sleeve, and the snap-fit ​​groove is opened along the length direction of the snap-fit ​​slider.

[0019] The beneficial effects of this improvement are as follows: the snap-fit ​​groove is used for the insertion of the convex strip, and the insertion of the convex strip into the snap-fit ​​groove ensures the stability of the connection between the protective sleeve and the guide sleeve. When assembling the protective sleeve and the guide sleeve, the convex strip is inserted into the snap-fit ​​groove, and the snap-fit ​​groove is used to ensure the stability of the connection between the protective sleeve and the guide sleeve.

[0020] In order for the rubber ring to be simultaneously embedded in the limiting ring groove, and for the embedded rubber ring to form a seal at the connection between the protective sleeve and the guide sleeve:

[0021] As a further improvement to the above technical solution: the size of the limiting ring groove matches the size of the rubber ring, and the thickness of the rubber ring is the same as the depth of the limiting ring groove.

[0022] The beneficial effects of this improvement are: after the protective sleeve is connected to the guide sleeve, the rubber ring is simultaneously embedded in the limiting ring groove, and the embedding of the rubber ring forms a seal at the connection between the protective sleeve and the guide sleeve.

[0023] To ensure the stability of the connection between the protective sleeve and the guide sleeve through the formed two-way interlocking:

[0024] As a further improvement to the above technical solution: the inner wall of the guide sleeve is provided with four clearance grooves at equal intervals around the circumference with a 90° interval. The size of the clearance groove matches the size of the snap-fit ​​slider, and the size of the convex strip matches the size of the snap-fit ​​groove.

[0025] The beneficial effects of this improvement are as follows: When assembling the protective sleeve and the guide sleeve, they are first connected by the mutual engagement of the external thread and the internal thread. When the locking slider meets the relief groove, the external thread and the internal thread are disconnected, pushing the protective sleeve to continue sliding into the guide sleeve, embedding the locking slider into the relief groove. At the same time, the convex strip is embedded into the locking groove, and the bidirectional locking ensures the stability of the connection between the protective sleeve and the guide sleeve.

[0026] In order to install a sealing ring on the inner wall of the guide sleeve, the sealing effect of the guide sleeve can be improved:

[0027] As a further improvement to the above technical solution: the mounting ring is a circular ring structure, and the inner circumference of the mounting ring is provided with equally spaced screw holes. The sealing ring is made of fluororubber and installed on the inner wall of the guide sleeve.

[0028] The beneficial effects of this improvement are as follows: during use, the guide sleeve is installed by inserting a bolt into the threaded hole. The inner wall of the guide sleeve is equipped with a sealing ring, which can improve the sealing effect of the guide sleeve. Attached Figure Description

The end of the positioning inner tube 124 away from the inner wall of the annular groove 121 is inserted into the outer tube sliding groove 123. The rubber head 126 is inserted into the outer tube sliding groove 123 through interference fit and shock absorption. Spring 125 is connected and then slidably connected to the positioning inner tube 124; when the rubber ring 12 is compressed, the positioning outer tube 122 slides and touches the rubber head 126. When the rubber head 126 slides, it compresses the shock-absorbing spring 125. The shock-absorbing spring 125 is used to buffer the impact force during deformation. When the positioning inner tube 124 slides, it drives the rubber head 126 to move. When the rubber head 126 touches the inner wall of the outer tube groove 123, the shock-absorbing spring 125 is also used to buffer the impact force through deformation. There are four snap-fit ​​sliders 13. The four snap-fit ​​sliders 13 are installed on the outer wall of the protective sleeve 11 at equal intervals of 90°. The snap-fit ​​sliders 13 are used to connect with the internal thread 23. To achieve the assembly and connection of the protective sleeve 11 and the guide sleeve 21, the snap-fit ​​slider 13 has a snap-fit ​​groove 14 on the side away from the protective sleeve 11. The snap-fit ​​groove 14 is opened along the length direction of the snap-fit ​​slider 13. The snap-fit ​​groove 14 is used for the insertion of the convex strip 25.
