Description

Technical Field

[0001] This invention relates to the field of slag inclusion detection, specifically to a device and method for detecting oxide slag inclusions in aluminum alloy round aluminum rods. Background Technology

[0002] Aluminum is a relatively new metal. Due to its superior properties, such as good machinability, excellent physical properties, and high recyclability, aluminum and its alloys have gradually come into focus for developing the national economy and industry to improve people's living standards. Aluminum and its alloys have been widely used in power machinery, machinery manufacturing, and other fields. However, various inclusions are inevitably present in aluminum alloys. The presence of these inclusions disrupts the continuity of the alloy, thereby reducing the mechanical properties of the casting material and eventually developing into macroscopic cracks that cause the entire part to fail.

[0003] Existing microscopes still have the following problems when in use: When observing the material to be tested, existing microscopes can only observe one side of the material placed on the stage first. When observing the other side of the material, the material needs to be removed and flipped over. Such flipping operation is inconvenient and requires re-limiting the position of the material to be tested, making the operation steps cumbersome.

[0004] Therefore, it is necessary to invent a device and method for detecting oxide inclusions in aluminum alloy round aluminum rods to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum alloy round aluminum rod oxide inclusion detection device and detection method to solve the problem mentioned in the background art that the existing microscope can only observe one side of the material placed on the stage when observing the material to be tested. When observing the other side of the material, it is necessary to remove the material and flip it over. Such flipping operation is inconvenient and requires re-limiting the position of the material to be tested, and the operation steps are cumbersome.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device and method for detecting oxide inclusions in aluminum alloy round aluminum rods, comprising a microscope body, wherein side plates are fixedly connected to both sides of the bottom stage of the microscope body, and the side plates have through holes inside, and further comprising:

[0007] The adjustment assembly has a rotating rod 1 rotatably connected inside the through hole, and the rotating rod 1 has a movable groove inside. The movable groove is slidably connected to a rotating rod 2 through a spring 1. The end of the rotating rod 2 is provided with a clamping component for clamping the sample disc, so as to clamp sample discs of different diameters.

[0008] The limiting assembly includes an annular plate fixedly sleeved on the outer ring of the rotating rod, which moves within an annular groove inside the side upright plate. The annular groove is connected to a through hole, which is connected to a channel and a vertical groove. A vertical rod is fixedly connected to the inner wall of the vertical groove, and a limiting block is movably sleeved on the outer ring of the vertical rod. The limiting block is movably connected to the vertical groove by a spring, and the limiting block matches the limiting groove inside the annular plate to ensure the fixed angular position of the sample disc after flipping.

[0009] Preferably, square protrusions are fixedly connected to both sides of one end of the rotating rod two. The end of the rotating rod two connected to the protrusions is "T"-shaped, and the outer wall of the square protrusions and the outer wall of the rotating rod two are attached to the inner wall of the movable groove to achieve a sliding connection. Furthermore, the "T"-shaped end of the rotating rod two is always located inside the movable groove, ensuring the stability of the rotating rod two moving inside the rotating rod one.

[0010] Preferably, the two ends of the spring one are fixedly connected to the inner wall of the movable groove and the "T"-shaped end of the rotating rod two with a protrusion, respectively, so that the clamping components on both sides can clamp and fasten the sample disc under the pushing force of the spring one.

[0011] Preferably, the clamping component includes a circular plate, a notch, a short rod, and a clamping plate. The circular plate is fixedly connected to the end of the rotating rod two located outside the rotating rod one, and the upper and lower ends of the circular plate are symmetrically provided with notches. The inner wall of the notch is fixedly connected to the short rod, and the outer ring of the short rod is movably sleeved with an inclined clamping plate, which can move inside the notch.

[0012] Preferably, the outer ring of the short rod is movably sleeved with a torsion spring, and the two ends of the torsion spring are fixedly connected to the side wall of the clamping plate and the inner wall of the notch, respectively. When the two clamping plates are pushed in opposite directions, the two clamping plates clamp the sample disc under the action of the torsion force of the torsion spring.

[0013] Preferably, the limiting block consists of a square block at the bottom and a triangular block fixedly connected to the top of the square block, wherein the side wall of the square block is attached to the inner wall of the vertical groove and is slidably connected up and down, and the triangular block passes through the channel connected to the vertical groove until it reaches the through hole.

[0014] Preferably, the upper end of the second spring is fixedly connected to the bottom square block and the inner wall of the vertical groove in the limiting block. The second spring applies force to push the front end of the limiting block to match the limiting groove, thereby limiting the rotation angle of the entire rotating rod one. At the same time, when the rotating rod one is subsequently turned to drive the annular plate to rotate, the inclined surface of the inner wall of the annular groove abuts against the inclined surface of the pointed end of the limiting block, thereby synchronously pushing the limiting block to achieve a downward movement, which facilitates the self-locking and unlocking rotation of the rotating rod one.

[0015] This invention also provides a method for detecting oxide inclusions in aluminum alloy round aluminum rods, using the aforementioned device for detecting oxide inclusions in aluminum alloy round aluminum rods. The specific operating steps are as follows:

[0016] Step 1: Selection of aluminum round bars. Select aluminum round bars with a diameter of 350-500mm and a length of 6000mm.

[0017] Step 2: Selection of test pieces. Cut a 20mm thick test piece from one-third of the way from the tail of the aluminum round bar, and perform water grinding and polishing on both sides of the test piece.

[0018] Step 3: Use the main body of the microscope to observe the tissue on both sides of the specimen;

[0019] Step 4: Take samples from the center, R / 2 and edge of the specimen for high-magnification metallographic examination. In order to clarify the type of inclusion defect, perform scanning electron microscopy and energy dispersive spectroscopy analysis on the defect area.

[0020] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0021] This invention clamps the sample disc on both sides by moving two sets of clamping plates, and the two rotating rods on both sides can extend and retract. This makes it convenient to clamp and limit the sample discs of different diameters, so as to facilitate the subsequent observation of the original disc. Furthermore, the observation surface of the entire sample disc can be adjusted by flipping the rotating rod. Once the adjustment is completed, there is no need to fix the sample disc again, making the operation more convenient.

[0022] When the rotating rod is flipped, the limiting groove inside the annular plate rotates and abuts against the pointed end of the limiting block, simultaneously pushing the limiting block to descend. As the annular plate continues to rotate, when the limiting groove inside the annular plate aligns with the tip of the limiting block again, the second spring pushes the front end of the limiting block to match the limiting groove again, fixing the rotation angle of the entire sample disc for subsequent testing.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This invention provides, for example Figure 1-7 The device and method for detecting oxide inclusions in aluminum alloy round aluminum rods shown include a microscope body 1, with side plates 2 fixedly connected to both sides of the bottom stage of the microscope body 1, and through holes 3 opened inside the side plates 2. It also includes:

[0035] The adjusting component 4 has a rotating rod 401 rotatably connected inside the through hole 3. The rotating rod 401 has a movable groove 403 inside, and a rotating rod 402 is slidably connected inside the movable groove 403 through a spring 405. The end of the rotating rod 402 is provided with a clamping component 406 for clamping the sample disc 6, so as to clamp sample discs 6 of different diameters.

[0036] The limiting component 5 has an annular plate 501 fixedly sleeved on the outer ring of the rotating rod 401. The annular plate 501 moves inside the annular groove 503 set inside the side plate 2. The annular groove 503 is connected to the through hole 3. The through hole 3 is connected to the channel 505 and the vertical groove 504. The inner wall of the vertical groove 504 is fixedly connected to the upright rod 506. The outer ring of the upright rod 506 is movably sleeved with the limiting block 507. The limiting block 507 is movably connected to the vertical groove 504 through the second spring 508. The limiting block 507 matches the limiting groove 502 set inside the annular plate 501 to ensure the fixed angle position of the sample disc 6 after flipping.

[0037] Square protrusions 404 are fixedly connected to both sides of one end of the rotating rod 402. The end of the rotating rod 402 connected to the protrusions 404 is "T" shaped. The outer wall of the square protrusions 404 and the outer wall of the rotating rod 402 are attached to the inner wall of the movable groove 403 to achieve a sliding connection. The "T" shaped end of the rotating rod 402 is always located inside the movable groove 403 to ensure the stability of the rotating rod 402 moving inside the rotating rod 401.

[0038] The two ends of the spring 405 are fixedly connected to the inner wall of the movable groove 403 and the "T"-shaped end of the rotating rod 402 with the protrusion 404. Under the pushing force of the spring 405, the clamping parts 406 on both sides clamp and fasten the sample disc 6.

[0039] The clamping component 406 includes a circular plate 4061, a notch 4062, a short rod 4063, and a clamping plate 4064. The circular plate 4061 is fixedly connected to the end of the rotating rod 402 located outside the rotating rod 401. The upper and lower ends of the circular plate 4061 are symmetrically provided with notches 4062. The short rod 4063 is fixedly connected to the inner wall of the notch 4062. The inclined clamping plate 4064 is movably sleeved on the outer ring of the short rod 4063. The clamping plate 4064 can move inside the notch 4062.

[0040] A torsion spring is movably sleeved on the outer ring of the short rod 4063, and the two ends of the torsion spring are fixedly connected to the side wall of the clamping plate 4064 and the inner wall of the notch 4062, respectively. When the two clamping plates 4064 are pushed in opposite directions, the two clamping plates 4064 clamp the sample disc 6 under the action of the torsion force of the torsion spring.

[0041] The limiting block 507 consists of a square block at the bottom and a triangular block fixedly connected to the top of the square block. The side wall of the square block is attached to the inner wall of the vertical groove 504 and is slidably connected up and down. The triangular block passes through the channel 505 connected to the vertical groove 504 until it reaches the through hole 3.

[0042] The upper end of the second spring 508 is fixedly connected to the bottom square block and the inner wall of the vertical groove 504 in the limiting block 507. The second spring 508 applies force to push the front end of the limiting block 507 to match the limiting groove 502, thereby limiting the rotation angle of the entire rotating rod 401. At the same time, when the rotating rod 401 is moved to drive the annular plate 501 to rotate, the inclined surface of the inner wall of the annular groove 503 abuts against the inclined surface of the pointed end of the limiting block 507, thereby synchronously pushing the limiting block 507 to achieve a downward movement, which facilitates the self-locking and unlocking rotation of the rotating rod 401.

[0043] This invention also provides a method for detecting oxide inclusions in aluminum alloy round aluminum rods, using the aforementioned device for detecting oxide inclusions in aluminum alloy round aluminum rods. The specific operating steps are as follows:

[0044] Step 1: Selection of aluminum round bars. Select aluminum round bars with a diameter of 350-500mm and a length of 6000mm.

[0045] Step 2: Selection of test pieces. Cut a 20mm thick test piece from one-third of the way from the tail of the aluminum round bar, and perform water grinding and polishing on both sides of the test piece.

[0046] Step 3: Use the microscope body 1 to observe the tissue on both sides of the specimen;

[0047] Step 4: Take samples from the center, R / 2 and edge of the specimen for high-magnification metallographic examination. In order to clarify the type of inclusion defect, perform scanning electron microscopy and energy dispersive spectroscopy analysis on the defect area.

[0048] Working principle: When using an aluminum alloy round aluminum rod oxide inclusion detection device and method, the sample disc 6 is first positioned and installed. This is achieved by first moving two opposing clamping plates 4064 on one side, causing the clamping ends of these plates to clamp the sample disc 6 on both sides under the force of the torsion spring connected to the outer ring of the short rod 4063. Subsequently, the sample disc 6 is pushed towards the side plate 2, which in turn moves the other two clamping plates 4064 to clamp the other end of the sample disc 6 (refer to...). Figure 2As shown, the sample disc 6 is placed horizontally. The rotating rod 402, which is telescopically connected to the rotating rod 401 via a spring 405, has a clamping component 406 at its end that can clamp sample discs 6 of different diameters. The surface of the sample disc 6 is then observed through the eyepiece of the microscope body 1 to determine the test results. When it is necessary to test the other side of the sample disc 6, it is simply flipped. Twisting one side of the rotating rod 401 is sufficient to flip the entire sample disc 6. After flipping the sample disc 6 180 degrees, the other side can be observed. Simultaneously, when the rotating rod 401 is flipped, the annular plate 501, which is fixedly sleeved on the outer ring of the rotating rod 401, rotates synchronously within the annular groove 503. The limiting slot 502 inside the annular plate 501 abuts against the pointed end of the limiting block 507 as the annular plate 501 rotates, ensuring that the annular plate 501 remains stationary during rotation. The inclined surface of the inner wall of the annular groove 503 inside 501 also abuts against the inclined surface of the pointed end of the limiting block 507, thereby synchronously pushing the limiting block 507 to achieve a downward movement, and simultaneously squeezing the second spring 508, until the pointed end of the limiting block 507 completely leaves the annular groove 503. Subsequently, during the continuous rotation of the annular plate 501, when the limiting groove 502 inside the annular plate 501 corresponds again with the tip of the limiting block 507, the second spring 508... Under the action of the thrust, the front end of the limiting block 507 is pushed to match the limiting slot 502 again, thereby completing the limitation of the rotation angle of the entire rotating rod 401. The limiting block 507 is movably sleeved on the outer ring of the upright rod 506 to ensure the stability of the up and down movement of the limiting block 507 and to ensure that the limiting block 507 and the limiting slot 502 will not be misaligned. In this way, the rotation angle of the entire sample disc 6 is fixed, so as to facilitate the observation and detection of the other side of the sample disc 6 and obtain the results.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
