Description

Technical Field

[0001] This utility model relates to the field of diamond production equipment, and in particular to a six-sided top press for cobalt diamond sintering. Background Technology

[0002] Cobalt-based diamond sintering is a diamond sintering process that uses cobalt as a binder. The optimal sintering temperature range is 720℃-750℃, and the sintering time is 5-15 minutes. It requires a high-pressure environment to achieve good bonding between diamond particles and the cobalt matrix. The six-sided press is a special equipment that provides extreme conditions for the synthesis of superhard materials. It applies pressure to the sample from three directions (X, Y, and Z) through a structure of six working cylinders. Existing six-sided presses can generally only provide the same heating effect in each direction, which cannot meet some special processing requirements. Therefore, it is necessary to design a six-sided press for cobalt-based diamond sintering that can individually control the heating degree in each direction to meet different production needs and has strong adaptability. Summary of the Invention

[0003] The purpose of this invention is to provide a six-sided top press for cobalt-based diamond sintering, which can realize triaxial differentiated heating to meet different types of processing needs, and the equipment has stronger applicability.

[0004] The technical solution adopted is as follows:

[0005] A six-sided top press for cobalt-based diamond sintering includes a frame, which comprises four C-shaped frames with inward openings spaced at 90-degree intervals. The ends of the C-shaped frames are fixedly connected. Each of the four C-shaped frames on the side of the frame has a horizontally mounted hydraulic cylinder. Each of the upper and lower ends of the frame has a vertically mounted hydraulic cylinder. The free end of each hydraulic cylinder is connected to a top hammer. Each hydraulic cylinder has a parallel-mounted adjusting cylinder on its side. A hydraulic station connected to both the hydraulic cylinders and the adjusting cylinders is located on the outside of the frame. Each adjusting cylinder has a mounting base at its end, and each mounting base is equipped with a light wave heating unit.

[0006] Preferably, each of the mounting bases is equipped with an infrared ranging sensor, which is parallel to the corresponding adjusting cylinder, and the frame is equipped with multiple reflectors corresponding to the infrared ranging sensors.

[0007] Preferably, the C-shaped frame is provided with reinforcing ribs at all turns.

[0008] Preferably, each of the mounting bases is provided with a horizontal sliding frame, and the light wave heating unit is fixed on the horizontal sliding frame.

[0009] Compared to existing technologies, the advantages are:

[0010] By adjusting the position of each light wave heating unit using adjustable hydraulic cylinders, and by adjusting the power of the light wave heating units, different heating degrees can be achieved in different directions of cobalt-based diamond. By realizing triaxial differentiated heating, different types of processing needs can be met, making the equipment more versatile. Attached Figure Description

[0016] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown:

[0017] Example 1: A six-sided top press for cobalt-based diamond sintering includes a frame, which includes four C-shaped frames 1 with inward openings and spaced 90 degrees apart. The ends of the C-shaped frames 1 are fixedly connected, and the four C-shaped frames 1 together form the frame. Working cylinders 3 are horizontally arranged on the four C-shaped frames 1 on the side of the frame. The horizontally arranged working cylinders 3 are all at the same height, and adjacent working cylinders 3 are perpendicular to each other.

[0018] The frame is equipped with working cylinders 3 vertically at both the top and bottom. The two vertically arranged working cylinders 3 extend coaxially. The free ends of the working cylinders 3 are connected to top hammers 4. The top hammers 4 are used to directly contact the side of the cobalt-based diamond. The six top hammers 4 in different directions support the six end faces of the cobalt-based diamond.

[0019] Adjusting cylinders 5 are arranged parallel to each other on the side of the working cylinders 3. A hydraulic station 11 is set on the outside of the frame and is connected to both the hydraulic cylinders and the adjusting cylinders 5. The hydraulic station 11 is used to control the extension and retraction of each working cylinder 3 and the adjusting cylinder 5. Each adjusting cylinder 5 can be controlled to extend and retract independently. Each end of the adjusting cylinder 5 is provided with a mounting base 6. A light wave heating unit 8 is installed on the mounting base 6. A power supply box 12, a water cooling mechanism 13 and a controller 14 connected to the light wave heating unit 8 are set on the outside of the frame, so as to control the heating power of each light wave heating unit 8 independently.

[0020] The position of each light wave heating unit 8 is adjusted by adjusting the oil cylinder 5, and the power of the light wave heating unit 8 is adjusted to achieve different heating degrees in different directions of cobalt-based diamond to meet different types of processing requirements.

[0021] Example 2: A six-sided top press for cobalt-based diamond sintering includes a frame, which includes four C-shaped frames 1 with inward openings and spaced 90 degrees apart. The ends of the C-shaped frames 1 are fixedly connected, and the four C-shaped frames 1 together form the frame. Reinforcing ribs 2 are provided at the bends of the C-shaped frames 1. Working cylinders 3 are horizontally arranged on the four C-shaped frames 1 on the side of the frame. The horizontally arranged working cylinders 3 are all at the same height, and adjacent working cylinders 3 are perpendicular to each other.

[0022] The frame is equipped with working cylinders 3 vertically at both the top and bottom. The two vertically arranged working cylinders 3 extend coaxially. The free ends of the working cylinders 3 are connected to top hammers 4. The top hammers 4 are used to directly contact the side of the cobalt-based diamond. The six top hammers 4 in different directions support the six end faces of the cobalt-based diamond.

[0023] Adjusting cylinders 5 are arranged parallel to each other on the side of the working cylinders 3. A hydraulic station 11 is provided on the outside of the frame, which is connected to both the hydraulic cylinders and the adjusting cylinders 5. The hydraulic station 11 is used to control the extension and retraction of each working cylinder 3 and the adjusting cylinder 5. Each adjusting cylinder 5 can be controlled to extend and retract independently. Each end of the adjusting cylinder 5 is provided with a mounting base 6. A horizontal sliding frame 7 is provided on each mounting base 6. A light wave heating unit 8 is installed on the horizontal sliding frame 7. The horizontal sliding frame 7 is used to adjust the position of the light wave heating unit 8 in the horizontal direction.

[0024] Infrared ranging sensors 9 are installed on each mounting base 6. The infrared ranging sensors 9 are parallel to the corresponding adjusting cylinders 5. Multiple reflectors 10 are installed on the frame, each corresponding to an infrared ranging sensor 9. The position of the light wave heating unit 8 is determined by measuring the distance between the infrared ranging sensor 9 and the reflector 10.

[0025] The outer side of the frame is equipped with a power supply box 12, a water cooling mechanism 13 and a controller 14 connected to the light wave heating unit 8, so as to individually control the heating power of each light wave heating unit 8. The position of each light wave heating unit 8 is adjusted by adjusting the oil cylinder 5. By adjusting the power of the light wave heating unit 8, different heating degrees of cobalt-based diamond in different directions can be achieved to meet different types of processing needs.

[0026] The working principle is as follows: When cultivating cobalt-based diamonds, the semi-finished product is placed between each top hammer 4, and each working cylinder 3 is controlled to extend and press against each end face of the semi-finished product. According to the production requirements of cobalt-based diamonds, the extension and retraction of the adjusting cylinder 5 are adjusted individually, and the position of the light wave heating unit 8 is measured by the infrared ranging sensor 9. The horizontal sliding frame 7 is used to adjust the position of the light wave heating unit 8 in the horizontal direction and to adjust the power of the light wave heating unit 8 individually to meet different types of processing requirements, making the equipment more adaptable.
