Description

Technical Field

[0001] This invention relates to the technical field of diamond synthesis, and in particular to a multi-mode cutting device for synthetic diamond rods with more than 60 cavities. Background Technology

[0002] Synthetic diamond rods (commonly known as synthetic diamond rods) are generally synthesized using high-temperature, high-pressure (HPHT) technology. In the process of artificially synthesizing diamonds, a six-sided press is used to produce synthetic diamonds. Graphite rods are placed in the synthesis chamber and, after being subjected to high temperature and pressure by the six-sided press, become synthetic rods containing diamonds. Then, the diamond synthetic rods need to be manually broken open in a timely manner to observe whether the crystal form of the diamond crystals on the cross-section and longitudinal section meets the standards, so as to adjust the pressure and temperature for the next synthetic rod.

[0003] As six-sided top presses become increasingly larger, the size of the synthesis chamber is also gradually increasing, from φ38mm to over φ70mm. Due to the increasing diameter of the synthesis chamber, the size of the synthetic rod is also constantly growing. This significantly increases the difficulty of manually breaking open the synthetic rod: the high temperature of the rod can easily cause burns to the hands; flying fragments can cause injury; and the excessively large diameter of the rod prevents it from being broken open quickly enough to adjust subsequent pressure and temperature, reducing the yield of high-quality diamonds within the rod. Therefore, a device capable of rapidly cutting large-cavity synthetic diamond rods is needed. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a multi-mode cutting device for synthetic diamond rods with more than 60 cavities.

[0005] The technical solution of the present invention is: a multi-mode cutting device for synthetic diamond rods with more than 60 cavities, comprising a housing, a pressure cylinder, a placement platform, a cutter, and a limiting device; the pressure cylinder is located at the center of the top surface of the housing, and the placement platform is correspondingly located on the bottom surface of the housing; the cutter is vertically mounted on the placement platform; the limiting device comprises two identical limiting blocks, which are fixedly mounted parallel to each other on both sides of the cutter and are symmetrical about the cutter.

[0006] The cutter is triangular prism-shaped, with its bottom surface fixed to the placement platform, and the projection of its top edge in the height direction is located at the middle of the bottom surface.

[0007] The limiting block is a solid triangular prism with a semi-circular transverse groove in its middle. The bottom of the transverse groove is lower than the height of the cutter. The top of the limiting block is higher than the top edge of the cutter.

[0008] A control device is installed on the outside of the enclosure, which is connected to an AC power source.

[0009] Preferably, a safety door is installed on the front of the enclosure. The device also includes an electromagnetic relay, with the controller circuit serving as the main circuit, and contacts for the control circuit are located on the safety door. The device can only start normally when the safety door is completely closed, preventing injury to the operator.

[0010] Preferably, the diameter of the transverse groove is greater than or equal to the diameter of the synthetic rod. This allows the synthetic rod to be placed directly into the transverse groove while preventing angular displacement and avoiding any deviation in the transverse cutting angle.

[0011] Preferably, the top angle of the cutter is a vertex angle α, where 30° ≤ α < 150°; the top angle of the limiting block is β, where 30° < β ≤ 150°, and α < β. Different angles can be matched with synthetic rods of different diameters.

[0012] Preferably, the length of the cutter is greater than the length of the synthetic rod, enabling the synthetic rod to be completely longitudinally cut.

[0013] Preferably, the length of the limiting block is less than or equal to the length of the cutter. After ensuring that the synthetic rod can be restricted, the length of the limiting block is shortened to save materials.

[0014] Preferably, a guide rod is connected to the limiting block; baffles are provided at both ends of the placement platform, the guide rod extends through the baffles, and two adjusting nuts are provided on the guide rod, respectively located on both sides of the baffles. This allows the limiting device to adapt to various synthetic rod sizes without replacement.

[0015] Furthermore, the transverse groove is arc-shaped, and the diameter of this arc-shaped groove is much larger than the diameter of the synthetic rod. This limiting device can adapt to various synthetic rod sizes without replacing the limiting block.

[0016] The beneficial effects of the present invention are as follows: The multi-mode cutting device for synthetic diamond rods with 60 or more cavities of the present invention has the following advantages:

[0017] 1. The sealed enclosure prevents the synthetic rods from scattering during the breaking process, making it safer.

[0018] 2. It can quickly cut the synthetic rod crosswise or longitudinally, making it easy to observe the cut surface and adjust the subsequent synthesis conditions, thereby increasing the proportion of high-quality diamond material.

[0019] 3. It avoids burns or injuries to the human body caused by manually cutting synthetic rods. At the same time, the device can only be started normally when the safety door is completely closed, avoiding crush injuries to the operator.

[0020] 4. The device is easy to operate and occupies little space, and can be placed on-site in the diamond synthesis process. Attached Figure Description

[0030] Example 1: See Figures 1-4 6-7, A multi-mode cutting device for synthetic diamond rods with more than 60 cavities, comprising a housing 01, a pressure cylinder 1, a placement platform 2, a cutter 3, and a limiting device; the pressure cylinder 1 is located at the center of the top surface inside the housing 01, and the placement platform 2 is correspondingly located on the bottom surface inside the housing 01; the cutter 3 is vertically mounted on the placement platform 2; the limiting device includes two identical limiting blocks 4, which are fixedly mounted parallel to each other on both sides of the cutter 3, symmetrical about the cutter 3; the cutter 3 is sandwiched between the two limiting blocks 4, allowing the synthetic rod 5 to be placed between the two limiting blocks 4, with the top of the cutter 3 abutting against the synthetic rod 5, enabling longitudinal cutting of the synthetic rod 5.

[0031] The cutter 3 is triangular prism-shaped, with its bottom surface fixed to the placement platform 2, and the projection of its top edge in the height direction is located in the middle of the bottom surface.

[0032] The limiting block 4 is a solid triangular prism with a semi-circular transverse cutting groove 41 in its middle. The bottom of the transverse cutting groove 41 is lower than the height of the cutter 3, and the top of the limiting block 4 is higher than the top edge of the cutter 3. The synthetic rod 5 can be placed in the transverse cutting groove 41, and the top of the cutter 3 abuts against the middle of the synthetic rod 5, which facilitates the transverse cutting of the synthetic rod 5.

[0033] A control device 03 is installed on the outside of the enclosure 01, and the control device 03 is connected to an AC power supply.

[0034] The housing 01 has a safety door 02 installed on its front. The device also includes an electromagnetic relay, with the controller circuit serving as the main circuit. The safety door 02 has contacts for the control circuit. The device can only start normally when the safety door 02 is completely closed, preventing injury to the operator.

[0035] The diameter of the transverse groove 41 is greater than or equal to the diameter of the synthetic rod 5. The synthetic rod 5 can be directly placed into the transverse groove 41, while avoiding angular deviation of the synthetic rod 5 and preventing the phenomenon of transverse angle skew.

[0036] The top angle of the cutter 3 is the vertex angle α, where 30° ≤ α < 150°; the top angle of the limiting block 4 is β, where 30° < β ≤ 150°, and α < β. Different angles can be matched with synthetic rods 5 of different diameters.

[0037] The length of the cutter 3 is greater than the length of the synthetic rod 5, and it can completely cut the synthetic rod 5 longitudinally.

[0038] The length of the limiting block 4 is less than or equal to the length of the cutter 3. After ensuring that the synthetic rod 5 can be restricted, the length of the limiting block 4 is shortened to save materials.

[0039] The steps for using this device are as follows:

[0040] ①Preparation: Open safety door 02, and select a matching limit block 4 according to the size of the synthetic rod 5, and place it in the center of the placement platform 2;

[0041] ② Cross-cutting: Place the synthetic rod 5 in the cross-cutting groove 41 of the two limit blocks 4, close the safety door 02, start the pressure cylinder 1, and cross-cut the synthetic rod 5;

[0042] ③Longitudinal cutting: Open safety door 02, place one of the two synthetic rods 5 between the two limit blocks 4, remove the other rod, close safety door 02, start pressure cylinder 1, and longitudinally cut synthetic rod 5;

[0043] ④ Observation: After opening safety door 02 and taking out the two longitudinally cut parts, observe the three parts of the synthetic rod 5 as a whole.

[0044] Example 2: See Figures 5-7Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that: a guide rod 42 is connected to the limiting block 4; baffles 21 are provided at both ends of the placement platform 2, and the guide rod 42 passes through the baffles 21. Two adjusting nuts 6 are provided on the guide rod 42, and the two adjusting nuts 6 are respectively located on both sides of the baffle. This allows the limiting device to adapt to various sizes of synthetic rods 5 without replacement. The cross-cut groove 41 is arc-shaped, and the diameter of the arc-shaped groove is much larger than the diameter of the synthetic rod 5. This limiting device can adapt to various sizes of synthetic rods 5 without replacing the limiting block 4.
