Description

Technical Field

[0001] This utility model relates to the field of steel sample testing technology, and specifically discloses a steel sample testing and analysis device. Background Technology

[0002] With the rapid development of industry, steel is widely used in daily life. Due to its high strength, it is widely favored by people. As the application of steel gradually increases, the use of steel sample testing devices in steel production also increases. In steel sample testing, hardness, purity, and other properties must be accurately tested to ensure the reliability of steel quality. Hardness testing devices are the most common products. However, most existing steel sample hardness testing devices have relatively simple structures, making them inconvenient to move around during use. At the same time, fixing steel samples during testing is troublesome, the operation procedures are cumbersome, and the work efficiency is low.

[0003] Chinese patent (patent number: CN212059635U, disclosing a steel sample testing device) includes a cabinet with a hydraulic lifting rod installed at the corner of the bottom. Casters are installed at the bottom of the cabinet and inside the hydraulic lifting rod. A cabinet door is installed on the front of the cabinet, with a handle corresponding to the door. A control panel is installed on the upper left corner of the cabinet door, including adjustment buttons and an emergency stop button. A fixing plate is installed at the center of the end of the cabinet. Compared with existing steel sample testing devices, this new design improves the convenience, operability, accuracy, and practicality of the steel sample testing device.

[0004] However, although the above-mentioned device can fix steel samples, it only relies on electromagnet adsorption, and the fixation effect is not good. Especially when the steel sample is subjected to high pressure during the testing process, the sample is prone to displacement or even falling off the worktable, which has low safety and affects the testing efficiency, and cannot meet the usage requirements.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4A steel sample testing and analysis device includes a support frame 1, a support plate 2 fixedly connected to the upper end face of the support frame 1, a linear guide rail 3 fixedly connected to the upper end face of the support plate 2, two symmetrically distributed sliders 4 slidably connected to the outer wall of the linear guide rail 3, clamping plates 5 fixedly connected to the upper end face of each slider 4, bent rods 6 rotatably connected to the left and right sides of the front end face of the support plate 2 via rotating shafts, a cylinder 7 installed at the bottom of the support frame 1, the output end of the cylinder 7 extending into the interior of the support frame 1 and fixedly connected to a movable seat 8, a first guide post 9 fixedly connected to the front end face of the slider 4, a second guide post 10 fixedly connected to the left and right sides of the front end face of the movable seat 8, and strip-shaped guide holes penetrating through the outer walls of the bent rods 6, the two guide holes being movably fitted onto the outer walls of the first guide post 9 and the second guide post 10 respectively.

[0023] In this embodiment: the support frame 1 serves as the basic support structure, on which the support plate 2 is fixedly connected. The linear guide rail 3 installed on the support plate 2 and the two sliders 4 slidably connected thereon provide a precise linear movement basis for the clamping mechanism.

[0024] The clamping plate 5, which is slidably connected to the slider 4, has a V-shaped groove 17 on its opposite surface that can effectively adapt to steel samples with different cross-sectional shapes, increase the contact area and friction, and significantly improve the adaptability and stability of clamping.

[0025] The bending rod 6, which is rotatably connected to the front end of the support plate 2 via a rotating shaft, and the cylinder 7 installed at the bottom of the support frame 1 together constitute the driving mechanism. The output end of the cylinder 7 is connected to the movable seat 8. The second guide post 10 on the movable seat 8 and the first guide post 9 on the slider 4 are respectively inserted into the strip-shaped guide holes on both sides of the bending rod 6.

[0026] When the cylinder 7 drives the movable seat 8 to move up and down, the movement of the second guide post 10 in the strip hole of the bent rod 6 forces the bent rod 6 to rotate around its axis. The rotation of the bent rod 6 then drives the first guide post 9 through the strip hole on its other side, thereby driving the two sliders 4 to move synchronously towards or away from each other on the linear guide rail 3, and finally driving the two clamping plates 5 to clamp or release the sample, achieving efficient and stable clamping under one-button operation.

[0027] Hydraulic cylinders 12 are installed on the top seats 11 on both sides of the support frame 1. The hydraulic cylinders 12 drive the sliding sleeve 13 to move up and down. The sliding rod 14 inside the sliding sleeve 13 and the detection pressure ball 15 connected to its bottom end constitute the hardness detection head. The pressure sensor 16 at the top inside the sliding sleeve 13 can accurately sense the pressure applied during the detection process.

[0028] Multiple pillars 19 on the support frame 1 support the sample support plate 20, providing a stable and flat placement platform for the steel sample to be tested. The control panel 21 at the front end of the top seat 11 integrates the control cylinder 7, the hydraulic cylinder 12 and the data reading pressure sensor 16, realizing centralized and convenient operation of the entire testing process.

[0029] As a technical optimization of this utility model, the support frame 1 is fixedly connected to the left and right sides of the support frame, and a top seat 11 is fixedly connected to the top of the support frame. A hydraulic cylinder 12 is installed on the top of the top seat 11. The output end of the hydraulic cylinder 12 extends to the bottom of the top seat 11 and is fixedly connected to a sliding sleeve 13. A sliding rod 14 is slidably connected inside the sliding sleeve 13, and a detection pressure ball 15 is fixedly connected to the bottom end of the sliding rod 14.

[0030] In this embodiment: the hydraulic cylinder 12 provides a stable and controllable downward pressure, driving the sliding sleeve 13 and the internal slide rod 14 and the detection pressure ball 15 to press down on the sample surface. The slide rod 14 slides inside the sliding sleeve 13 to form a floating structure. In conjunction with the pressure sensor 16, the pressure applied to the sample can be controlled more precisely and the pressure value (a key parameter for hardness testing) can be measured in real time, ensuring the accuracy and reliability of hardness testing.

[0031] As a technical optimization of this utility model, a pressure sensor 16 is provided at the top of the inner part of the sliding sleeve 13.

[0032] In this embodiment, a pressure sensor 16 is provided at the top of the inner part of the sliding sleeve 13, which can more accurately control the pressure applied to the sample and measure the pressure value (a key parameter for hardness testing) in real time, ensuring the accuracy and reliability of hardness testing.

[0033] As a technical optimization of this utility model, V-grooves 17 are provided on the opposite sides of the two clamping plates 5.

[0034] In this embodiment, the V-groove 17 can more reliably clamp cylindrical, square or other angular steel samples, increase the contact area and friction, effectively prevent the sample from rolling or slipping during the testing process, and significantly improve the stability and safety of clamping.

[0035] As a technical optimization of this utility model, a long groove 18 is provided on the upper end surface of the support frame 1, and both bent rods 6 extend to the inner side of the support frame 1 through the long groove 18.

[0036] In this embodiment, the necessary space channel is provided for the bent rod 6 to extend from the front end of the support plate 2 into the interior of the support frame 1 to connect with the movable seat 8, ensuring smooth linkage of the drive mechanism.

[0037] As a technical optimization of this utility model, a plurality of pillars 19 are fixedly connected to the upper end face of the support frame 1, and a sample support plate 20 is fixedly connected to the top of the plurality of pillars 19.

[0038] In this embodiment: the sample support plate 20 is fixed above the support frame 1 by the support column 19, which provides a stable, horizontal and fixed support surface for the steel sample to be tested, so that the sample is in the optimal testing position, which is convenient for clamping and aligning the testing head, and improves the convenience and consistency of testing.

[0039] As a technical optimization of this utility model, a control panel 21 is installed on the front end face of the top seat 11, and the cylinder 7, hydraulic cylinder 12 and pressure sensor 16 are all electrically connected to the control panel 21.

[0040] In this embodiment: a control panel 21 is set up, and the cylinder 7, hydraulic cylinder 12, and pressure sensor 16 are electrically connected to it, so as to realize centralized control and display of the clamping action, hardness detection pressure application process and data acquisition of the entire device, which greatly simplifies the operation process and improves the detection efficiency and automation level.

[0041] The working principle and usage process of this utility model are as follows: In use, the operator places the steel sample to be tested on the sample support plate 20 above the support frame 1, and starts the cylinder 7 through the control panel 21. The piston rod of the cylinder 7 retracts downward, pulling the movable seat 8 downward within the support frame 1. The downward movement of the movable seat 8 drives the second guide post 10 fixed on it to move downward. The second guide post 10 is located in the strip-shaped guide hole below the bent rod 6. Its downward movement forces the bent rod 6 to rotate around the pivot connected to the support plate 2. When the bent rod 6 rotates, the first guide post 9 in the strip-shaped guide hole above it is subjected to force. Due to the guiding constraint of the strip-shaped hole, the first guide post 9 is driven, causing the two sliders 4 to slide synchronously towards the center on the linear guide rail 3. The sliders 4 sliding towards the center drive the clamping plates 5 connected to them to move synchronously towards the center. The V-shaped grooves 17 on the two clamping plates 5 contact and tightly clamp the two sides of the steel sample placed on the sample support plate 20, completing the stable fixation.

[0042] After the sample is fixed, the hydraulic cylinder 12 is activated via the control panel 21. The piston rod of the hydraulic cylinder 12 extends downward, pushing the sliding sleeve 13 downward. The sliding sleeve 13 drives the sliding rod 14 and the detection pressure ball 15 inside it to move downward until the detection pressure ball 15 contacts the sample surface. The hydraulic cylinder 12 continues to apply pressure, which is transmitted through the sliding sleeve 13. The sliding rod 14 can slide relative to the sliding sleeve 13. The pressure is transmitted to the detection pressure ball 15 at the bottom of the sliding rod 14, pressing it into the sample surface. At the same time, the applied pressure is detected in real time by the pressure sensor 16 at the top of the sliding sleeve 13 and converted into an electrical signal. The pressure data detected by the pressure sensor 16 is transmitted in real time to the control panel 21 for display and processing (for calculating hardness values, etc.).

[0043] After the test is completed, the control panel 21 controls the piston rod of the hydraulic cylinder 12 to retract, which drives the sliding sleeve 13, the slide rod 14 and the test pressure ball 15 to move upward away from the sample surface.

[0044] The piston rod of cylinder 7 is raised again via control panel 21, causing movable seat 8 to move upward. Movable seat 8 pushes the second guide post 10 upward, forcing bent rod 6 to rotate in the opposite direction, which in turn pushes the two sliders 4 to slide in opposite directions on linear guide rail 3 via first guide post 9, causing clamp 5 to release the sample, allowing the operator to remove the tested sample.
