Description

Technical Field

[0001] This utility model belongs to the field of steel performance verification technology, and more specifically, it relates to an impact verification device for high-performance impact-resistant steel. Background Technology

[0002] Impact testing of steel is a method to verify the impact resistance of steel through impact testing. The principle is to use an impact testing machine to impact the steel and measure its impact energy absorption capacity at a certain temperature, thereby evaluating the steel's impact resistance. Impact tests are usually conducted using the Charpy hammer method or the Pascal hammer method. Existing impact verification devices for high-performance impact-resistant steel require placing a notch in the center of the specimen before the test, so that the specimen breaks at the notch under impact, which is inconvenient. Therefore, this paper proposes an impact verification device for high-performance impact-resistant steel. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an impact verification device for high-performance impact-resistant steel, which can automatically place the test block in the correct position, thereby solving the problem mentioned in the background technology that before the test, the notch on the test block needs to be placed in the center so that the test block breaks at the notch under impact, which is inconvenient to operate.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant high-performance steel impact verification device, comprising a base plate and a pendulum impact mechanism. A support is fixed to the top surface of the base plate, and a top plate is fixed to the top surface of the support. A first sliding groove is formed on the top surface of the top plate, and a second sliding groove is formed inside the top plate. A slider is slidably connected to the inner side of the second sliding groove. A toothed groove is formed on the top surface of the slider, and a limit block is also fixed to the top surface of the slider. A first support and a second support are also fixed to the top surface of the top plate. An operating rod is rotatably connected between the first support and the second support. A torsion spring is fixed to the side of the first support away from the second support. One end of the torsion spring is fixedly connected to one end of the rotating shaft of the operating rod. An incomplete gear is also fixed to the lower end of the operating rod. The outer side of the incomplete gear meshes with the outer side of the toothed groove. A vertical block is also fixed to the top surface of the support. A test block groove is formed on the top surface of the vertical block, and a through groove is formed on the lower outer side of the vertical block.

[0005] As a preferred embodiment of this utility model, the first slide groove and the second slide groove are connected.

[0006] As a preferred embodiment of this utility model, the width of the first groove is smaller than the width of the second groove.

[0007] As a preferred embodiment of this utility model, the limiting block is located inside the first sliding groove.

[0008] As a preferred embodiment of this invention, the center of the incomplete gear coincides with the center of the rotating shaft of the operating lever.

[0009] As a preferred embodiment of this utility model, the inner side of the through groove is connected to the inner side of the test block groove, and the position of the through groove corresponds to the position of the first sliding groove.

[0010] As a preferred embodiment of this invention, the size of the through groove corresponds to the size of the first sliding groove.

[0011] This utility model provides an impact testing device for high-performance impact-resistant steel, which has the following advantages:

[0012] This impact-resistant high-performance steel impact verification device works by rotating the operating lever. One end of the slider enters the through groove on the vertical block, pushing the test block in the test block slot out from the other end of the through groove. When the limiting block on the slider abuts against the outer side of the vertical block, it is positioned exactly at the center of the pendulum impact mechanism. After releasing the operating lever, the slider moves out of the through groove on the vertical block and returns to its original position along the second sliding groove on the top plate. Under the action of gravity, the test block in the test block slot fills the position of the ejected test block. Through the above process, the problem of having to place the notch on the test block in the center before the test, so that the test block breaks at the notch under impact, is solved, which is inconvenient to operate.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: an impact-resistant high-performance steel impact verification device, including a base plate 1 and a pendulum impact mechanism 2. A bracket 3 is fixed to the top surface of the base plate 1, and a top plate 4 is fixed to the top surface of the bracket 3. A first sliding groove 5 is formed on the top surface of the top plate 4, and a second sliding groove 6 is formed inside the top plate 4. A slider 7 is slidably connected to the inner side of the second sliding groove 6. A toothed groove 8 is formed on the top surface of the slider 7, and a limit block 9 is also fixed to the top surface of the slider 7. A first support 10 and a second support 11 are also fixed to the top surface of the top plate 4. An operating rod 12 is rotatably connected between the first support 10 and the second support 11. A torsion spring 13 is fixed to the side of the first support 10 away from the second support 11. One end of the torsion spring 13 is connected to the rotating part of the operating rod 12. One end of the shaft is fixedly connected, and the lower end of the operating lever 12 is also fixed with an incomplete gear 14. The outer side of the incomplete gear 14 meshes with the outer side of the tooth groove 8. The top surface of the bracket 3 is also fixed with a vertical block 15. The top surface of the vertical block 15 is provided with a test block groove 16. The lower part of the outer side of the vertical block 15 is provided with a through groove 17. The first slide groove 5 and the second slide groove 6 are connected. The width of the first slide groove 5 is smaller than the width of the second slide groove 6. The limiting block 9 is located inside the first slide groove 5. The center of the incomplete gear 14 coincides with the center of the rotating shaft of the operating lever 12. The inner side of the through groove 17 is connected with the inner side of the test block groove 16. The position of the through groove 17 corresponds to the position of the first slide groove 5. The size of the through groove 17 corresponds to the size of the first slide groove 5.

[0023] The test block is placed into the test block slot 16 in the vertical block 15. The operating lever 12 is rotated downwards, causing the incomplete gear 14 to rotate. Simultaneously, the shaft of the operating lever 12 twists the torsion spring 13, and the incomplete gear 14 meshes with the toothed groove 8 on the slider 7, thereby causing the slider 7 to slide along the inner side of the second sliding groove 6. One end of the slider 7 enters the through groove 17 on the vertical block 15, pushing the test block in the test block slot 16 out from the other end of the through groove 17. When the limiting block 9 on the slider 7 abuts against the outer side of the vertical block 15, it is positioned exactly at the center of the pendulum impact mechanism 2. The lever is then released. After operating lever 12, under the action of torsion spring 13, operating lever 12 returns to its original position, and incomplete gear 14 rotates in the opposite direction, causing slider 7 to move out of through groove 17 on vertical block 15 and return to its original position along the second sliding groove 6 on top plate 4. Under the action of gravity, the test block in test block groove 16 fills the position of the ejected test block. Finally, by releasing the pendulum, the test block breaks at the notch. Through the above process, the problem of having to place the notch on the test block in the center before the test, so that the test block breaks at the notch under impact, is solved, which is inconvenient to operate.

[0024] The specific usage and function of this embodiment: The test block is placed in the test block slot 16 of the vertical block 15. Rotating the operating lever 12 downwards drives the incomplete gear 14 to rotate. Simultaneously, the rotating shaft of the operating lever 12 twists the torsion spring 13, causing the incomplete gear 14 to mesh with the toothed groove 8 on the slider 7. This causes the slider 7 to slide along the inner side of the second sliding groove 6. One end of the slider 7 enters the through groove 17 on the vertical block 15, pushing the test block in the test block slot 16 out from the other end of the through groove 17. When the slider 7... When the limiting block 9 abuts against the outer side of the vertical block 15, it is positioned exactly at the center of the pendulum impact mechanism 2. After the operating lever 12 is released, under the action of the torsion spring 13, the operating lever 12 returns to its original position, and the incomplete gear 14 rotates in the opposite direction, causing the slider 7 to move out of the through groove 17 on the vertical block 15 and return to its original position along the second sliding groove 6 on the top plate 4. Under the action of gravity, the test block in the test block groove 16 fills the position of the ejected test block. Finally, by releasing the pendulum, the test block breaks at the notch.
