Description

Technical Field

[0001] This utility model belongs to the field of crack detection technology, and in particular relates to a crack detection tool for the top hammer of a six-sided top press. Background Technology

[0002] In the synthesis of superhard materials (such as diamond and cubic boron nitride), a six-sided press is the core equipment for achieving high-temperature and high-pressure synthesis conditions. It uses six hammers to simultaneously apply pressure, raising the internal pressure of the synthesis chamber to 5-8 GPa and heating the temperature to 1200-2000℃, providing a crucial environment for the growth of superhard material crystals. As the core load-bearing component of the six-sided press, the hammers are typically made of cemented carbide. They are subjected to extreme high-temperature and high-pressure cyclic loads, material erosion within the chamber, and thermal stress impacts over long periods, making them prone to developing microcracks on their surface or inside.

[0003] If such cracks are not detected in time, they will rapidly propagate with each cycle of press operation, eventually leading to the sudden fracture of the top hammer. This will not only cause the scrapping of a single batch of products, but may also damage critical components such as the press chamber and hydraulic system due to the impact of the fragments, resulting in equipment downtime for several days to weeks, causing significant economic losses to superhard material manufacturers. In more serious cases, the flying debris from the fracture may cause safety accidents, threatening the personal safety of operators.

[0004] Due to the immaturity of automated detection technology, the mainstream method for detecting top hammer cracks in the superhard materials industry is currently manual inspection. Utility model patent "CN204679404U" proposes a technical solution for a top hammer crack detection tool. This tool slides on the surface of the top hammer, relying on the hand to sense when the tip of the hammer hook encounters a crack and causes a pause, thus determining the presence of a crack. This solution has three problems:

[0005] ① To ensure rigidity, the hammer hook must be made of steel wire with a diameter of 3mm-5mm. To keep the tip sharp, the tip of the hammer hook must be sharpened every day.

[0006] ②The tip of the hammer hook will wear down to half its length in about 5 days, at which point it must be replaced with a new hammer hook.

[0007] ③ After inspecting the cracks, workers need to continue with other operations, but there is no suitable place to put the inspection tools, which affects subsequent operations.

[0008] To address this issue, we provide a tool for detecting cracks in the top hammer of a six-sided top press, thereby resolving the problems mentioned above. Utility Model Content

[0009] The purpose of this utility model is to provide a crack detection tool for the top hammer of a six-sided top press. Through the cooperation of the handle, core cylinder and core needle, it solves the problem of inconvenience in the use of existing crack detection tools.

[0010] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0011] This utility model relates to a crack detection tool for a six-sided top press hammer, comprising a handle, a groove on the surface of the handle, a mounting groove on the surface of the groove, tempered glass magnetically attached to the inner cavity of the mounting groove, a threaded hole at one end of the handle, a core cylinder threadedly connected to the inner cavity of the threaded hole, a core needle inserted into the inner cavity of the core cylinder, the other end of the core needle bent and placed in the inner cavity of the groove, and a magnet fixedly connected to the surface of the handle and to one side of the groove.

[0012] The present invention is further configured such that a first magnetic ring is bonded to the inner cavity of the mounting groove by an adhesive, and a second magnetic ring for use with the first magnetic ring is bonded to the back of the tempered glass by an adhesive. The cooperation between the first magnetic ring and the second magnetic ring enhances the magnetic attraction and fixing effect between the tempered glass and the mounting groove, making the tempered glass installation more stable, while facilitating disassembly, cleaning or replacement, and ensuring the protective effect of the structure inside the groove.

[0013] The present invention is further configured such that the core tube is a hollow metal cylinder with a length of 100mm-300mm, an inner diameter of 0.4mm-1mm, and an outer diameter of 2mm-10mm. The core tube adopts a hollow metal cylinder structure, which not only ensures its own structural strength to withstand the force during detection, but also provides a stable guiding channel for the core needle, ensuring smooth movement of the core needle and improving the stability of the detection.

[0014] The present invention is further configured such that one end of the core tube is a threaded end and is threadedly connected to the inner cavity of the threaded hole, and the other end of the core tube is a bent end with a bending angle of 100 degrees to 160 degrees and a bending length of 2 mm to 10 mm. The diameter of the threaded hole is 2 mm to 10 mm. The threaded end of the core tube is easy to connect and fix with the threaded hole. The bending design allows the tip of the core needle to adapt to the curved surface of the top hammer or a specific detection angle, thereby improving the detection adaptability to different parts of the top hammer.

[0015] The present invention is further configured such that a limiting groove is formed on the surface of the handle and around the threaded hole, and a limiting ring is provided in the inner cavity of the limiting groove. The limiting ring is fixedly connected to the core tube. The cooperation between the limiting groove and the limiting ring restricts the screwing depth of the core tube in the threaded hole, avoids excessive screwing of the core tube leading to structural interference, and enhances the overall stability of the core tube after installation, preventing the core tube from shaking during testing.

[0016] The present invention is further configured such that the core needle is a metal wire with a diameter of 0.3mm-0.9mm and a length 200-300mm longer than the core tube, with 2mm-5mm protruding at the bend of the core tube as the detection tip. The core needle is made of a thin-diameter metal wire and is longer than the core tube, which not only improves the sensitivity to microcracks, but also compensates for tip wear by adjusting the exposed length, thus extending the service life of the core needle and reducing the replacement frequency.

[0017] The present invention is further configured such that the handle is made of nylon and is rectangular with rounded corners. This design not only has good insulation and wear resistance, but also improves the comfort of holding, avoids hand scratches during operation, and enhances the safety of use.

[0018] The present invention has the following beneficial effects.

[0019] 1. This utility model solves the problem of rapid wear and frequent maintenance required by existing testing tools. This tool uses a core needle and core cylinder cooperation structure. The core needle is designed with a fine diameter metal wire. Compared with the traditional 3-5mm diameter scribing hook, it reduces the contact area with the top hammer surface, reduces the wear rate, and eliminates the need to grind the tip every day. At the same time, the length of the core needle is greater than that of the core cylinder. When the tip is worn, the exposed length of the core needle can be adjusted to continue using it. This greatly extends the replacement cycle, reduces maintenance costs and operation interruption time, and improves testing efficiency.

[0020] 2. The magnets on the surface of the handle of this utility model can attract the tool to various positions of the six-sided press, which solves the problem of not having a suitable place to put the tool after testing, and avoids the loss of the tool or affecting subsequent operations. The tempered glass is installed in the mounting groove of the groove by magnetic attraction, which not only protects the bent part of the core needle in the groove, but also makes it easy to observe the testing status.

[0027] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figure 1-4 This utility model is a crack detection tool for a six-sided top press hammer, including a handle 1, a groove 2 on the surface of the handle 1, a mounting groove 3 on the surface of the groove 2, a tempered glass 4 magnetically attached to the inner cavity of the mounting groove 3, a threaded hole 5 at one end of the handle 1, a core cylinder 6 threadedly connected to the inner cavity of the threaded hole 5, a core needle 7 inserted into the inner cavity of the core cylinder 6, the other end of the core needle 7 bent and placed in the inner cavity of the groove 2, and a magnet 8 fixedly connected to the surface of the handle 1 and located on one side of the groove 2.

[0030] Specifically: the groove 2 is used to accommodate the bent part of the core needle 7, providing space for the testing operation. The tempered glass 4 covers the surface of the groove 2, which can protect the internal structure and facilitate the observation of the testing situation. The core cylinder 6 is stably installed and removed through the threaded engagement. The inner cavity of the core cylinder 6 provides a through channel for the core needle 7, which can move inside the core cylinder 6. Its other end is bent and placed in the inner cavity of the groove 2.

[0031] Example 2

[0032] Please see Figure 1-4 Based on Embodiment 1, a magnet ring 1 is bonded to the inner cavity of the mounting groove 3 with adhesive, and a magnet ring 2 for use with the magnet ring 1 is bonded to the back of the tempered glass 4 with adhesive. The core cylinder 6 is a hollow metal cylinder with a length of 100mm-300mm, an inner diameter of 0.4mm-1mm, and an outer diameter of 2mm-10mm. One end of the core cylinder 6 is a threaded end 61, which is threadedly connected to the inner cavity of the threaded hole 5. The other end of the core cylinder 6 is a bent end 62 with a bending angle of 100 degrees-160 degrees and a bending length of... The diameter of the threaded hole 5 is 2mm-10mm. A limiting groove 9 is opened on the surface of the handle 1 around the threaded hole 5. A limiting ring 10 is set in the inner cavity of the limiting groove 9. The limiting ring 10 is fixedly connected to the core tube 6. The core needle 7 is a metal wire with a diameter of 0.3mm-0.9mm and a length 200-300mm longer than the core tube 6. It protrudes 2mm-5mm at the bend of the core tube 6 as the tip of the test. The handle 1 is made of nylon and is a cuboid with rounded corners.

[0033] Specifically: the cooperation of magnet ring one and magnet ring two enhances the magnetic attraction and fixing effect between tempered glass 4 and mounting groove 3, making the tempered glass 4 more securely installed and facilitating disassembly, cleaning, or replacement. This ensures the protective effect of the structure within groove 2. The core cylinder 6 adopts a hollow metal cylindrical structure, which not only ensures its own structural strength to withstand the force during testing but also provides a stable guide channel for the core needle 7, ensuring smooth movement of the core needle 7 and improving the stability of the test. The threaded end 61 of the core cylinder 6 facilitates connection and fixing with the threaded hole 5. The bending design allows the tip of the core needle 7 to adapt to the curved surface of the top hammer or a specific testing angle, improving the accuracy of testing against different top hammer angles. The detection adaptability of the part is improved by the cooperation between the limiting groove 9 and the limiting ring 10, which limits the screwing depth of the core tube 6 in the threaded hole 5, avoiding excessive screwing of the core tube 6 and causing structural interference. At the same time, it enhances the overall stability of the core tube 6 after installation and prevents the core tube 6 from shaking during detection. The core needle 7 is made of fine-diameter metal wire and is longer than the core tube 6. This not only improves the sensitivity to micro-cracks, but also compensates for tip wear by adjusting the exposed length, extending the service life of the core needle 7 and reducing the replacement frequency. This design not only has good insulation and wear resistance, but also improves the comfort of holding, avoids hand scratches during operation, and enhances the safety of use.

[0034] The working principle of this utility model is as follows: The operator holds the handle 1, and the core cylinder 6 is fixed to one end of the handle 1 through the threaded connection between the core cylinder 6 and the threaded hole 5. The core needle 7 penetrates the inner cavity of the core cylinder 6, and its bent tip protrudes from the groove 2, contacting the surface of the top hammer of the six-sided press. When the tool is moved, the tip of the core needle 7 slides on the surface of the top hammer. If a crack is encountered, the tip will produce obvious feedback, and the operator can feel the presence of the crack by touch. After the tip of the core needle 7 is worn, it can be pulled outward with pliers to an appropriate length. The tempered glass 4 covers the groove 2 to protect the bent part of the core needle 7 and facilitate observation of the detection area. During the detection gap, the magnet 8 on the handle 1 can attract the tool to the metal surface of the press, etc., for convenient temporary storage. The tempered glass 4 is installed by magnetic attraction and can be removed at any time to maintain the internal structure of the groove 2. The limiting ring 10 and the limiting groove 9 cooperate to ensure the stable installation of the core cylinder 6.
