Description

Technical Field

[0001] The present invention relates to the field of steel physical testing, and in particular to an integrated steel performance testing device and testing method. Background Art

[0002] The reason for steel testing is that steel is subjected to tremendous pressure and load in various applications. Testing can ensure that its key properties such as strength, toughness and corrosion resistance meet the requirements, prevent safety accidents caused by material defects, and promptly detect potential defects and problems to extend the service life of steel and its products. Physical testing methods for steel mainly include tensile strength, yield strength, elongation, impact testing, hardness testing and other testing methods. However, existing testing methods need to rely on a variety of different equipment, and each device can only test a specific property of steel separately, which leads to low testing efficiency and time-consuming. In addition, existing testing methods mainly evaluate the performance of steel at room temperature or specific environments, and cannot perform real-time testing when the steel is burning or under extremely high temperature conditions. This means that in some extreme application scenarios, such as fire scenes or high-temperature industrial environments, it is impossible to provide effective performance evaluation, which limits its application under these conditions.

[0003] In the prior art, for example, the patent with publication number CN117074223B discloses a hardness testing device for steel testing, which includes a testing platform, a U-shaped frame fixed on the top of the testing platform, an electric push rod fixed on the top of the U-shaped frame, a hardness testing device body fixed on the bottom of the telescopic end of the electric push rod, and a fixed-point device, which includes a movable plate, a plurality of triangular blocks, two U-shaped plates, a telescopic arc column, and a movable plate, wherein the movable plate is slidably mounted on the top of the testing platform. Through the setting of the fixed-point device, under the action of the corresponding spring force of the movable block, the movable block pushes the movable plate to drive the vertical surface of the triangular block to collide with the outer wall of the telescopic arc column, and the telescopic arc column limits the position of the movable plate through the triangular block. The positions of the multiple triangular blocks correspond to the detection points of the steel, so that the staff can quickly switch the detection points of the steel to detect the hardness of the steel. However, although this technology has improved some of the original problems, there are still aspects that need to be further optimized to better meet actual detection needs.

[0004] 1. The above-mentioned existing technologies can only detect the hardness of the steel surface and lack the function of detecting other properties of the steel. Moreover, the above-mentioned existing technologies can only detect the hardness of steel in a normal state and cannot detect when the steel is at a high temperature or in other states. In other words, they are conventional detection methods and cannot detect the performance of steel in accordance with actual use requirements. Therefore, their applicability is low.

[0005] 2. The above-mentioned prior art mainly detects steel of a certain thickness and may not work properly for ultra-thick or ultra-thin steel that exceeds the design range. Moreover, the grinding force of the concave roller on the steel surface in the above-mentioned prior art depends on the spring force of the slider and the driving speed of the motor, which is difficult to control accurately. This may cause uneven grinding of the steel surface, making it impossible for the detection device to accurately detect the surface of the steel.

[0006] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing physical testing methods for steel. Summary of the Invention

[0044] The following combination Figures 1 to 13 The embodiments of the present invention are described in detail.

[0045] The embodiment of the present application discloses an integrated steel performance testing device and testing method, which explains that the present application is mainly used in the process of testing the physical properties of steel plates, and can perform preliminary clamping of the steel plates through the clamping unit, and after clamping, can also wipe off the dirt on the outside of the steel plates through the clamping device to ensure that the testing equipment can accurately test the steel plates; the present application can not only test the hardness of the steel plates through hardness testing equipment, but also drive the steel plates to bend through the clamping device to test the maximum bending degree of the steel plates, and can also heat the steel plates at high temperature before testing to test the bending degree and hardness changes of the steel plates under high temperature conditions, further improving the applicability of the present application.

[0046] Example 1: Reference Figure 1 、 Figure 2 and Figure 3 As shown, it includes a rectangular box 1, a through groove 10, a sliding groove 11, a T-shaped plate 12, an arc-shaped groove 13, a clamping unit 2, a steel plate 14, a flamethrower 15, a hardness detection device 16, a detection box 17 and a monitoring device 18. Through grooves 10 are provided at both ends of the rectangular box 1, and sliding grooves 11 are symmetrically opened on the bottom wall. T-shaped plates 12 are slidingly connected in the sliding grooves 11. An arc-shaped groove 13 is opened at one end of the T-shaped plate 12 away from the sliding groove 11, and the arc-shaped grooves 13 on the two T-shaped plates 12 located in the sliding groove 11 on one side are symmetrically distributed. When driven by external force, the T-shaped plates 12 can slide back and forth in the corresponding sliding grooves 11.

[0047] A clamping unit 2 for clamping the steel plate 14 is provided in the arc groove 13 , and the steel plate 14 is located in the clamping unit 2 . The clamping unit 2 can slide back and forth in the rectangular box 1 following the T-shaped plate 12 and clamp the steel plate 14 .

[0048] Flamethrowers 15 are installed on both sides of the rectangular box 1 , with the flame spraying ends of the flamethrowers 15 facing into the rectangular box 1 , so as to heat the steel plates 14 at high temperatures.

[0049] A hardness detection device 16 is slidingly provided on the bottom wall of the rectangular box 1 , and the detection end of the hardness detection device 16 faces one side of the steel plate 14 , and can extend to contact the outside of the steel plate 14 for performing hardness detection on the steel plate 14 .

[0050] A detection box 17 is provided on the top of the rectangular box 1, and a real-time monitoring device 18 for the surface condition of the steel plate 14 is installed inside. The detection box 17 cooperates with the flamethrower 15 and the hardness detection device 16 to simulate high-temperature environments that may be encountered in actual use, such as fire, and detects changes in the mechanical properties of the steel plate 14 at high temperatures, including strength, toughness and deformation resistance, to ensure its reliability and safety under extreme temperature conditions, thereby comprehensively evaluating the performance of the steel plate 14 in actual applications.

[0051] On the basis of the above, the present invention also proposes an integrated steel performance testing method, comprising the following steps:

[0052] S1, placement and clamping: insert the steel plate 14 into the rectangular box 1 through the through slot 10 on one side until the other side of the steel plate 14 is inserted into the clamping unit 2, and then the clamping unit 2 clamps the steel plate 14.

[0053] S2, hardness test: The hardness detection device 16 is then started to press against the steel plate 14 to perform a hardness test. During this process, the clamping unit 2 will scrape off the contaminants on the outside of the steel plate 14.

[0054] S3, bending test: start the clamping unit 2 to drive both sides of the steel plate 14 to bend. During this process, the shape change of the steel plate 14 is monitored in real time by the monitoring device 18 to monitor the bending degree of the steel plate 14.

[0055] S4, combustion test: a high-temperature flame is sprayed toward the steel plate 14 by the flamethrower 15 to test the bending degree and hardness change of the steel plate 14 under high temperature.

[0056] S5, result analysis, through the hardness testing device 16 and the monitoring device 18 feedback of the hardness test, bending test and combustion test process of the data collected, the comprehensive performance of the steel plate 14 is evaluated and analyzed to determine whether it meets the corresponding standards and usage requirements.

[0057] Continue to refer to Figure 3、 Figure 4 、 Figure 5 and Figure 6 As shown, the clamping unit 2 is used to clamp the steel plate 14; specifically, the clamping unit 2 includes an arc frame plate 20, a limit frame plate 21, a sliding block 22, a rotating shaft 23, an electric push rod 24, a friction wheel 25, an arc plate 26, a side shaft 27 and a reset spring 28. The arc frame plate 20 is slidably arranged in the arc groove 13. The arc frame plate 20 is symmetrically provided with a limit frame plate 21 on one side facing the inside of the rectangular box 1. The sliding block 22 is slidably provided in the limit frame plate 21. A rotating shaft 23 is provided between the corresponding sliding blocks 22 on the right, which rotate together. That is, when the arc frame plate 20 is driven by external force, it can slide up and down along the inner wall of the arc groove 13, and the limit frame plate 21 can move synchronously with the arc frame plate 20. At the same time, the sliding block 22 can drive the corresponding rotating shaft 23 to move up and down under the limit guide of the limit frame plate 21, and the rotating shaft 23 can rotate between the rotating shafts 23 when driven by external force.

[0058] An electric push rod 24 is provided between the sliding block 22 and the inner wall of the limiting frame plate 21 . The telescopic end of the electric push rod 24 is connected to the sliding block 22 and drives the sliding block 22 to move in the corresponding limiting frame plate 21 .

[0059] The outer side of the rotating shaft 23 is provided with a friction wheel 25 made of frosted material. The steel plate 14 is located between several friction wheels 25. The friction wheels 25 can rotate synchronously with the rotating shaft 23. When the steel plate 14 is inserted into the through groove 10, the electric push rod 24 indirectly drives the upper and lower corresponding rotating shafts 23 to drive the outer friction wheels 25 to move in the opposite direction to avoid the insertion path of the steel plate 14, so that one side of the steel plate 14 can be inserted into the through groove 10 on the other side. After the steel plate 14 is inserted, the electric push rod 24 indirectly drives the upper and lower corresponding rotating shafts 23 to move in the direction of the steel plate 14, so that the friction wheels 25 contact the upper and lower sides of the steel plate 14 respectively, and then slides in the sliding groove 11 through the T-shaped plate 12 while indirectly driving the friction wheels 25 to move on the steel plate 14, and then drives the friction wheels 25 to rotate in the opposite direction of the moving path again, so that the outer side of the steel plate 14 can be polished and the dirt on the outer side of the steel plate 14 can be cleaned.

[0060] In order to solve the problem that the rotating shaft 23 cannot clean the dirt in the middle of the steel plate 14, after the steel plate 14 is inserted into the through groove 10 on one side, the friction wheel 25 is used to grind part of the area of the steel plate 14. After grinding, the friction wheel 25 no longer contacts the steel plate 14. At this time, continue to push one side of the steel plate 14 into the other end of the through groove 10, and then repeat the above steps again to complete the grinding of the steel plate 14.

[0061] An arc-shaped plate 26 is slidingly provided in the arc-shaped frame plate 20, and one side of the arc-shaped plate 26 is located outside the arc-shaped frame plate 20 and is rotatably provided with a side shaft 27, and the outer side of the side shaft 27 is in contact with the outer side of the steel plate 14, and a return push spring 28 is provided between the arc-shaped plate 26 and the inner side wall of the arc-shaped frame plate 20. In the initial case, the return push spring 28 pushes the corresponding arc-shaped plate 26 to extend to the outside of the arc-shaped frame plate 20. After the steel plate 14 is inserted into the through groove 10 and contacts the corresponding side shaft 27, the arc-shaped plate 26 can be driven in reverse to be retracted into the arc-shaped frame plate 20, and in this process, the return push spring 28 clamps the steel plate 14 tightly through the arc-shaped plate 26 and the side shaft 27, and the side shaft 27 can rotate synchronously at the end of the arc-shaped plate 26 during the movement of the steel plate 14.

[0062] When the friction wheel 25 and the side shaft 27 contact the upper and lower and left and right sides of the steel plate 14 respectively, the arc frame plate 20 can be driven by external force to move up and down in the arc groove 13. Since the arc groove 13 is arc-shaped and the front and rear corresponding arc grooves 13 are symmetrically distributed, the arc frame plates 20 on both sides will indirectly drive the friction wheel 25 to drive the end faces of the steel plate 14 to bend in the same direction to test the bending resistance of the steel plate 14. According to the spacing adjustment of the T-shaped plates 12 on the front and rear sides in the sliding groove 11, the bending degree of the end faces of the steel plate 14 with different spacings can be achieved. One side of the steel plate 14 is limited by the external pushing device, so the steel plate 14 will not slide during the bending process.

[0063] During the bending test, the flamethrower 15 can be started to heat the steel plate 14 to simulate the high temperature environment that the steel plate 14 is exposed to during actual use, and the changes in the steel plate 14 can be recorded in real time through the monitoring device 18 and the hardness detection device 16 to facilitate recording by the staff.

[0064] When the steel plate 14 completes the test, it is moved to the initial position in the arc groove 13 through the arc frame plate 20, forcing the steel plate 14 to stop bending. Then, the steel plate 14 can be taken out of the rectangular box 1 through the through groove 10 again by an external pushing device.

[0065] It should be noted that the "external pushing device" proposed in the above implementation process is an existing technology. Its purpose is to move the steel plate 14 through the through groove 10 into the rectangular groove and limit the steel plate 14. After the test is completed, the steel plate 14 is moved out of the rectangular box 1, so it will not be described in detail.

[0066] Continue to refer to Figure 3 and Figure 6As shown, the side shaft 27 is provided with a linkage assembly 3 for making the side shaft 27 and the rotating shaft 23 rotate synchronously; specifically, the linkage assembly 3 includes a circular groove 30, a circular shaft 31, a driving key 32, a passive key 33 and a push spring 34, two circular grooves 30 are symmetrically opened inside the side shaft 27, a circular shaft 31 is slidingly set in the circular groove 30, and the circular shaft 31 is located on one side of the outer side of the circular groove 30 and is provided with several driving keys 32 distributed along its axis. The outer side of the friction wheel 25 is symmetrically provided with passive keys 33 corresponding to the circular shaft 31, and several passive keys 33 are evenly distributed along the outer side of the rotating shaft 23. Distribution, the driving key 32 is engaged with the corresponding passive key 33, the circular shaft 31 can move up and down in the corresponding circular groove 30, and during the rotation of the side shaft 27, the circular shaft 31 can be driven to rotate synchronously, and the circular shaft 31 can drive the friction wheel 25 to rotate through the driving key 32 on its outside and the passive key 33 on the outside of the corresponding friction wheel 25; a push spring 34 is jointly provided between the circular shaft 31 and the inner wall of the circular groove 30, and the push spring 34 always pushes the corresponding circular shaft 31 in the initial state to drive the driving key 32 to engage with the corresponding passive key 33.

[0067] In the actual working process, when the steel plate 14 enters the rectangular box 1, the electric push rod 24 indirectly drives the friction wheel 25 to move in the direction away from the steel plate 14 without contacting the steel plate 14, that is, the friction wheel 25 is not in contact with the steel plate 14 at this time. Therefore, even if the side shaft 27 contacts the side of the steel plate 14 and drives the friction wheel 25 to rotate through the driving key 32 and the passive key 33, the friction wheel 25 will not scrape the outside of the steel plate 14 to avoid interfering with the travel path of the steel plate 14. When the steel plate 14 is inserted, the electric push rod 24 drives the friction wheel 25 to contact the steel plate 14, and the circular shaft 31 will The corresponding circular groove 30 is adaptively extended and retracted, and then the T-shaped plate 12 moves in the sliding groove 11. During this process, the side shaft 27 rubs against the outer side of the steel plate 14 and rotates. The friction wheel 25 is driven to rotate by the cooperation of the driving key 32 and the passive key 33. At this time, the rotation direction of the friction wheel 25 is opposite to the travel direction of the T-shaped plate 12, so the outer side of the steel plate 14 can be rotated and polished. After the flamethrower 15 heats the steel plate 14, impurities such as an oxide layer or grease may appear on the outer side of the steel plate 14. At this time, these impurities can be effectively removed by the rotation and polishing of the friction wheel 25, thereby ensuring the accuracy of subsequent detection.

[0068] The spacing between the two corresponding side shafts 27 can be automatically adjusted according to the different widths of the steel plates 14. After the steel plate 14 contacts the side shaft 27, the friction wheel 25 will drive the passive key 33 corresponding to the driving key 32 on one side to descend and engage with the driving key 32, ensuring that when the side shaft 27 indirectly drives the driving key 32 to move, the friction wheel 25 will still drive the passive key 33 to engage with it when it descends, and the friction wheel 25 will initially drive the corresponding passive key 33 not to engage with the driving key 32, so that the spacing adjustment of the side shaft 27 will not be affected.

[0069] Example 2: Reference Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, on the basis of embodiment 1, in order to drive the T-shaped plate 12 to reciprocate in the sliding groove 11 and the arc frame plate 20 to slide in the arc groove 13, a driving unit 4 is provided on the outside of the rectangular box 1; specifically, the driving unit 4 includes a reciprocating screw 40, a driving screw 41, a driving frame plate 42, a driving ring 43, a driven shaft 44, a transmission shaft 1 45, a transmission shaft 2 46, a ratchet 47, an outer gear ring 48, a driving shaft 49 and a driving gear 410, and the two reciprocating screws 40 rotate and insert In the corresponding sliding groove 11, the reciprocating screw 40 is threadedly connected to the corresponding T-shaped plate 12. The other side of the reciprocating screw 40 passes through the outer wall of the rectangular box 1 and is connected through a belt drive. A bidirectional thread groove is provided on the outside of the reciprocating screw 40, and the reciprocating screw 40 can drive the corresponding two T-shaped plates 12 to reciprocate in relative or opposite directions in the sliding groove 11 during rotation, and the two reciprocating screws 40 can rotate synchronously through the belt drive, and the movement directions of the two corresponding T-shaped plates 12 on the left and right are consistent.

[0070] Four driving screw rods 41 corresponding to the T-shaped plates 12 are rotatably inserted at the bottom of the rectangular box 1, and a driving frame plate 42 is also provided on one side of the driving screw rod 41 located inside the rectangular box 1. Four driving rings 43 corresponding to the driving screw rods 41 are also rotatably provided at the bottom of the rectangular box 1, and the driving rings 43 are connected to the corresponding driving screw rods 41 by means of key grooves. That is, when the driving rings 43 are driven to rotate by external force, the driving screw rods 41 can be driven to rotate by means of key grooves. During the rotation process, the driving screw rods 41 are threadedly connected to the rectangular box 1, so that they can move back and forth in the up and down directions, and during the movement process, Since it is key-matched with the drive ring 43, there will be no interference. The drive rings 43 are connected to each other by belt transmission, so that the drive rings 43 can rotate synchronously. A driven shaft 44 is provided on the side of the arc frame plate 20 facing the inner wall of the rectangular box 1, and the driven shaft 44 is slidably inserted into the corresponding drive frame plate 42, and a bidirectional thread groove is also provided on the outside of the drive screw 41. Therefore, when the drive screw 41 rotates, the arc frame plate 20 can be driven to move up and down in the arc groove 13 through the drive frame plate 42 and the driven shaft 44. During this process, the driven shaft 44 will slide inside the drive frame plate 42.

[0071] A transmission shaft 45 is also provided at the bottom of the rectangular box 1, and the transmission shaft 45 is connected to the driving ring 43 on one side through a belt transmission. A support plate is also provided on one side of the rectangular box 1, and a transmission shaft 2 46 is rotatably provided on the support plate. The upper end of the transmission shaft is connected to one side of the corresponding reciprocating screw 40 through a bevel gear transmission. That is, the transmission shaft 1 45 and the transmission shaft 2 46 can respectively drive the corresponding driving screw 41 and the reciprocating screw 40 to rotate through the belt transmission and the bevel gear transmission when driven by external force.

[0072] The lower ends of the transmission shaft 1 45 and the transmission shaft 2 46 are both sleeved with ratchet teeth 47, and the outer sides of the two ratchet teeth 47 are sleeved with outer gear rings 48. A driving shaft 49 is provided at the bottom of the rectangular box 1, and a driving gear 410 is provided on the outer side of the driving shaft 49 to mesh with the two outer gear rings 48. Therefore, one side of the driving shaft 49 can be connected to an external driving motor to drive the driving gear 410 to rotate, and the driving gear 410 can drive the two outer gear rings 48 to rotate on the outer sides of the corresponding ratchet teeth 47. Due to the one-way transmission characteristics of the ratchet teeth 47, when the driving gear When the wheel 410 drives the two outer gear rings 48 to rotate clockwise, only the ratchet teeth 47 on the outside of the transmission shaft 2 46 will be activated, and the reciprocating screw 40 will be indirectly driven to rotate through the transmission shaft 2 46, driving the T-shaped plate 12 to move. Conversely, when the outer gear ring 48 rotates counterclockwise, the ratchet teeth 47 on the outside of the transmission shaft 1 45 will be activated to drive the transmission shaft 1 45 to rotate, so that the transmission shaft 1 45 can drive the driving screw 41 to rotate, thereby realizing that the driving screw 41 and the reciprocating screw 40 can be driven to rotate by only one external drive motor.

[0073] Example 3: Reference Figure 12 and Figure 13 As shown, on the basis of Example 1 and Example 2, in order to prevent the monitoring device 18 from being damaged by burning by the flame when the flamethrower 15 sprays flames, a monitoring slot 5 is provided on the side of the detection box 17 facing the interior of the rectangular box 1, and storage slots 50 are provided on the inner walls on both sides of the monitoring slot 5. A blocking plate 51 is slidably provided in the storage slot 50, a pulling spring 52 is provided between the blocking plate 51 and the inner wall of the storage slot 50, and a driving plate 53 is provided on the side of the blocking plate 51 located outside the storage slot 50.

[0074] When the flamethrower 15 sprays flames, the sprayed combustion airflow will push the driving plate 53 to drive the sealing plate 51 to move toward the middle of the monitoring slot 5, so that the sealing plate 51 blocks the monitoring slot 5 to prevent high temperature and flame from entering the detection box 17 and causing damage to the monitoring device 18. When the flamethrower 15 no longer sprays flames, the sealing plate 51 can be pulled into the storage slot 50 by the corresponding pulling spring 52, so that the monitoring end of the monitoring device 18 can continue to monitor the steel plate 14 through the monitoring slot 5.
