Description

Technical Field

[0001] This utility model belongs to the field of artificial diamond technology, and in particular relates to a sealing top cover impregnation device for a six-sided hydraulic press. Background Technology

[0002] Six-sided top presses are divided into hinged and tie-rod types. The maximum pressure that the six-sided and eight-sided pressure chambers can reach is about 15-30 GPa. The sealing cover is a key component of the six-sided top hydraulic press, mainly serving as a guide and seal. To avoid damage to the piston, the sealing cover is usually made of ductile iron. However, due to its casting process, ductile iron has some internal pores, which can easily cause air bubbles during impregnation. These air bubbles can cause the sealing cover to slide and fall off, affecting the overall impregnation efficiency. Therefore, we propose an impregnation device for the sealing cover of a six-sided top hydraulic press. Utility Model Content

[0003] The purpose of this invention is to provide a sealing cap impregnation device for a six-sided hydraulic press. This device can further fix the cap by moving and inserting the plugs on both sides, thereby improving the sealing performance of the cap.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A six-sided hydraulic press sealing cap impregnation device includes an impregnation cylinder and a cap inserted into the top of the impregnation cylinder. The cap is stepped, and the side of the portion of the cap inside the impregnation cylinder has recesses. The recesses are symmetrically arranged, and a plug is inserted into the recess. A pin is fixed to the end of the plug away from the recess. A fixing tube is fixed to the side of the impregnation cylinder at the end of the pin away from the recess. A stop is fixed to the side of the fixing tube away from the impregnation cylinder. The pin slides inside the fixing tube. A baffle is fixed to the end of the pin away from the recess. A fastener is provided on one side of the baffle.

[0005] Furthermore, a spring is fitted around the outside of the pin, with one end of the spring fixed to the side of the stop block and the other end fixed to the side of the baffle.

[0006] Furthermore, a rotating connecting seat is fixed to the side of the impregnation cylinder, and the rotating connecting seats are arranged symmetrically.

[0007] Furthermore, the fastener includes a crank rod rotatably connected inside the rotating connecting seat. Both ends of the crank rod away from the rotation point are arranged parallel to the axis of the impregnation cylinder.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a six-sided hydraulic press sealing top cover 2 impregnation device, including an impregnation cylinder 1 and a top cover 2 inserted into the top of the impregnation cylinder 1. The top cover 2 is arranged in a stepped shape. The side of the part of the top cover 2 located inside the impregnation cylinder 1 is provided with a concave hole 3. The concave holes 3 are symmetrically arranged. A plug post 4 is snapped into the concave hole 3. A pin 5 is fixed to the end of the plug post 4 away from the concave hole 3. A fixing tube 6 is fixed to the side of the impregnation cylinder 1 at the end of the pin 5 away from the concave hole 3. A stop block 7 is fixed to the side of the fixing tube 6 away from the impregnation cylinder 1. The pin 5 slides inside the fixing tube 6. A baffle 8 is fixed to the end of the pin 5 away from the concave hole 3. A fastener is provided on one side of the baffle 8.

[0017] A spring 9 is fitted outside the pin 5. One end of the spring 9 is fixed to the side of the stop block 7, and the other end is fixed to the side of the baffle 8.

[0018] A rotating connecting seat 10 is fixed on the side of the impregnation cylinder 1, and the rotating connecting seats 10 are arranged symmetrically.

[0019] The fastener includes a crank 11 rotatably connected inside the rotating connecting seat 10. Both ends of the crank 11 away from the rotation point are arranged parallel to the axis of the impregnation cylinder 1. One end of the crank 11 is located on the side of the baffle 8, and the other end of the crank 11 is connected to an adjusting component.

[0020] The adjusting component includes a threaded end 12 fixed to the side of the impregnation cylinder 1, and a connecting rod 13 hinged to the side of the crank 11. The end of the connecting rod 13 away from the crank 11 is rotatably connected to a drive cylinder 14, and the end of the drive cylinder 14 away from the connecting rod 13 is threadedly connected to the threaded end 12.

[0021] The drive cylinder 14 is connected to the connecting rod 13 in a free rotational manner. When the drive cylinder 14 rotates independently, since the drive cylinder 14 is connected to the threaded end 12 by a thread, it can move back and forth in the axial direction of the connecting rod 13 as the rotation direction changes.

[0022] When the drive cylinder 14 moves toward the threaded end 12, it pulls the connecting rod 13 to move. The connecting rod 13 rotates freely near the end of the crank 11 and pulls the crank 11 to start rotating along the point where it is connected to the rotating connecting seat 10, so that the other end of the crank 11 moves away from the baffle 8. Conversely, after the drive cylinder 14 rotates in the opposite direction, it can drive the crank 11 to move toward the baffle 8 to press the baffle 8, and then drive the baffle 8 to move the pin 5 toward the concave hole 3 side, inserting the insertion post 4 at the front end of the pin 5 into the concave hole 3. Then, by moving and inserting the insertion posts 4 on both sides, the top cover 2 can be further fixed, improving the sealing performance of the top cover 2.

[0023] A crossbar 15 is fixed inside the rotating connecting seat 10. A crank rod 11 is rotatably connected to the outside of the crossbar 15. A torsion spring 16 is sleeved on the outside of the crossbar 15. The torsion springs 16 are symmetrically arranged. One end of each torsion spring 16 is fixed to the side of the crank rod 11, and the other end is fixed to the inner wall of the rotating connecting seat 10.

[0024] With the torsion spring 16 and spring 9 configured as described above, after the crank 11 moves away from the baffle 8, the pin 5 carrying the plug post 4 can automatically reset, thereby allowing the top cover 2 to be quickly removed for convenient use.

[0025] Meanwhile, ribs 17 are fixed on the side of the top cover 2. Several ribs 17 are equidistantly arranged along the axial direction of the top cover 2. After the top cover 2 is closed, a roughening treatment area 18 is provided on the inner wall of the impregnation cylinder 1 at the position of the ribs 17 on the top cover 2, which further improves the friction between the top cover 2 and the impregnation cylinder 1 and further improves its sealing performance.

[0026] The working principle of this utility model is as follows: A crank rod 11 and a rotating connecting seat 10 are installed on both sides of the impregnation cylinder 1. By rotating the crank rod 11, the pin 5 can be moved. Then, when the top cover 2 is in the closed state, it can be inserted into the concave hole 3 through the insertion post 4 to further reinforce the top cover 2, improve the sealing performance of the top cover 2 after it is closed, and prevent the top cover 2 from falling off.
