Description

Technical Field

[0001] This application relates to the field of testing equipment technology, specifically a metal impact testing device. Background Technology

[0002] Metal impact testing, as a core method for evaluating the mechanical properties of materials, focuses on the toughness, fracture behavior, and energy absorption capacity of materials under transient high strain conditions, and is a key indicator for measuring the properties of metals.

[0003] Currently, metal impact testing is typically conducted using metal impact testing equipment. Mainstream testing methods include the Charpy V-notch impact test, the Charpy U-notch impact test, the Izod impact test, and high / low temperature pendulum oscilloscope impact test. Among these, the Charpy V-notch impact test is one of the most commonly used methods. During the test, a standard specimen with a V-notch is placed on the support of a pendulum impact testing machine. The pendulum is released to impact the specimen at a certain speed, and the height of the pendulum's rebound or the energy required for fracture is recorded, thereby assessing the material's notch sensitivity and toughness. For example, Chinese utility model patent CN218601068U discloses a metal impact testing device. Through the arrangement of a connecting block, a fixing rod, an impact block, a protective frame, a placement block, a placement groove, and a detection block, the impact block moves downwards under gravity, impacting the detection block and performing testing. The protective frame effectively prevents the detection block from flying out.

[0004] However, in the implementation of the above technical solution, the overall height of the impact block is fixed and the maximum impact force is also fixed. When impact tests are required on different types of metals, there may be situations where the impact force is insufficient or excessive. For example, for brittle metal materials, a lower impact force is usually required for toughness assessment to avoid excessive impact causing instantaneous fracture and making it impossible to accurately measure energy absorption. For metal materials under extreme working conditions, it is necessary to simulate high-speed impact to verify their dynamic response under high energy.

[0005] Therefore, it is necessary to provide a metal impact testing device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a metal impact testing device, which sets the impact component to an adjustable height so that it has different impact forces, thereby meeting different testing requirements.

[0014] Support plate, which is slidably connected to support base;

[0015] The rotating shaft, wherein the rotating shaft bearing is mounted on the support plate;

[0016] Connecting rod, which is fixedly connected to the rotating shaft;

[0017] An impact block, which is disposed at the other end of the connecting rod, has a groove.

[0018] In the implementation of the technical solution of this application, by sliding the support plate and the support base, the height of the support plate can be changed when conducting impact tests on different metals, so that the impact component can have different impact forces, thus meeting the diverse impact test requirements.

[0019] Furthermore, the support base is provided with at least two threaded holes, the support plate is provided with a fixing block, and a knob is provided in the threaded hole.

[0023] The beneficial effects of this application are: the metal impact testing device provided by this application, by slidingly connecting the support plate and the support seat, can make the impact component have different impact forces when conducting impact tests on different metals by changing the height of the support plate, thus meeting the diverse impact test requirements.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] Example 1: As Figure 1As shown, this application provides a metal impact testing device, mainly used for impact testing of metal materials to evaluate their metal properties. The device includes a vertical plate 1, which is arranged in pairs and forms the support of the entire device. A support base 2 is provided on the vertical plate 1, and an impact component 4 is provided on the support base 2. The metal impact testing device also includes a placement component, which includes placement blocks 5, which are arranged in pairs with a gap between them. The placement blocks 5 have notches 6. During the impact test, the metal to be tested is placed on the notches of the placement blocks 5, and then the impact test is performed through the impact component 4.

[0035] like Figures 1-2 As shown, the impact assembly 4 includes a rotating shaft 41 and a support plate 3. The support plate 3 is fixedly installed on the upper end of the support base 2. The rotating shaft 41 is bearing-connected to the support plate 3, and a connecting rod 42 is fixedly installed at one end of the rotating shaft. The connecting rod 42 is adapted to rotate synchronously with the rotating shaft 41. An impact block 43 is provided at the end of the connecting rod 42, and a groove 44 is provided on the impact block 43. During the impact test, the rotating shaft is rotated, which synchronously drives the connecting rod 42 to rotate, placing the impact block 43 on top. After falling, the impact block 43 will impact the metal material to be tested, which is placed on the notch 6 of the placement block 5, thereby completing the impact test of the metal material. Figure 2 The image shows a state during the impact test;

[0036] To facilitate the display of the magnitude of the impact energy, such as Figures 1-2 As shown, a scale 45 is fixed on the support plate 3, and a pointer 46 is also fixed on the rotating shaft 41. The pointer 46 corresponds to the scale on the scale 45. During the impact test, the connecting rod 42 will drive the pointer 46 to rotate, thereby determining the angle before impact and the rising angle after impact of the impact block 43 through the pointer, and calculating the impact energy in combination with the torque of the impact block 43. The specific conversion method is not described in detail in this embodiment. For the specific principle, please refer to the technical parameters of the semi-automatic pendulum impact testing machine of model JB-300B.

[0037] like Figure 1 As shown, in order to facilitate the collection of metal materials after the experiment, a collection box 7 is also provided on one side of the placement block 5. When the metal material breaks, the broken metal will fall into the collection box 7, which will facilitate subsequent analysis.

[0038] Example 2: Since there are many types of metals, it is necessary to select the appropriate impact force for different materials when conducting impact tests. For example, for brittle materials, a lower impact force is usually required for toughness assessment to avoid excessive impact causing instantaneous fracture and making it impossible to accurately measure energy absorption. For metal materials under extreme working conditions, it is necessary to simulate high-speed impact to verify their dynamic response under high energy. However, the upper limit of the impact force in Example 1 is fixed and cannot meet diverse needs. Therefore, improvements are made in this example.

[0039] like Figure 1 As shown, the support plate 3 is no longer fixedly connected to the support base 2, but is slidably mounted on the support base 2. In order to fix it after sliding, the support plate 3 is provided with a fixing block 47. The support base 2 is provided with multiple threaded holes 48, and a knob 49 is provided in the threaded holes 48. After the sliding support plate 3 changes its height, it is fixed by the knob 49, so that the impact component 4 has different heights and thus different gravitational potential energies, thereby meeting the impact test requirements of different metal materials.

[0040] It should be noted that, in order to match the impact components 4 at different heights, in this embodiment, the length of the connecting rod 42 can be adjusted by an additional extension structure, such as... Figure 4 As shown, the extension structure includes a sleeve 50 connected to one end of the connecting rod 42. The sleeve 50 is threadedly connected to the connecting rod 42, and the other end of the sleeve 50 is threadedly connected to an extension rod 51. After adjustment, the impact block 43 is fixed on the extension rod 51, thereby cooperating with the placement component to complete the impact test.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
