Description

Technical Field

[0001] The present invention relates to the technical field of material strength detection, and in particular to a material strength detection device for producing filing cabinets. Background Art

[0002] In the context of the continuous development of archive management, metal materials (especially aluminum plates) have been widely used in the production of filing cabinets due to their excellent strength, light weight and corrosion resistance. At present, the bending strength of metal materials is an important indicator for evaluating the bearing capacity and deformation resistance of filing cabinets. In this context, bending testing machines, as a common equipment for testing the performance of metal materials, are widely used to test the maximum stress that materials can withstand under bending loads, thereby reflecting the material's ability to resist bending deformation.

[0003] The existing publication number CN112161860A discloses a plate strength detection device for construction projects, which includes a detection box, which includes a box body, a box door is movably installed on the front surface of the box body through a hinge, a bottom box is arranged below the box body, the upper end of the bottom box passes through and is fixedly connected to the lower surface of the box body, the upper surface of the bottom box is fixedly connected to a bottom plate, the bottom plate is located inside the box body, a hydraulic lifting column is fixedly installed in the middle of the bottom plate, a detection device is arranged above the bottom plate, the detection device is located inside the box body, the detection device includes a rectangular block, the interior of the rectangular block is hollow, a rear plate is fixedly connected to the rear surface of the rectangular block, the middle part of the rear plate is made of glass, the upper end of the rear plate is fixedly connected to a strip plate, and the rear end of the strip plate passes through the rear inner wall of the box body.

[0004] Although the above technical solution can distinguish the thickness of the plate before the plate strength test, it has the advantage of saving manpower and time to distinguish the thickness of the plate. However, in the prior art, although the traditional bending testing machine can provide basic bending strength testing, the existing bending testing machine still has certain limitations. The current equipment can generally only perform a single-mode bending strength test on metal materials. It usually uses a pressure head to perform a pressure test on the metal material. However, only using a single mode for strength testing cannot effectively simulate the stress distribution and other stress conditions in the actual filing cabinet structure. After the filing cabinet uses metal materials (such as aluminum plates) as the main material, the load it bears during use is not only simple bending, but may also be affected by multiple forces such as long-term backlog. The single detection mode cannot effectively simulate the multiple stress conditions of the filing cabinet in actual use, resulting in the test results being often relatively simple. Therefore, a new type of material strength testing equipment for filing cabinet production is needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a material strength testing device for filing cabinet production, so as to solve the problem that the existing bending testing machine proposed in the above background technology uses a single mode for strength testing and cannot effectively simulate the stress distribution and other stress conditions in the actual filing cabinet structure.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] Reference Figure 1-Figure 5 , a material strength testing device for filing cabinet production, comprising a machine base 1, a testing platform 2 arranged on the machine base 1, a support base 3 symmetrically arranged on the testing platform 2, and a hydraulic cylinder 4 vertically arranged on the testing platform 2, the testing platform 2 is also provided with a control system, the control system can be a digital control panel or computer software, used to set test parameters, control force speed, record data, etc., an outer frame 5 is provided at the output end of the hydraulic cylinder 4, at least three groups of detection components 6 are arranged in the outer frame 5, and the three groups of detection components 6 are evenly arranged along the left and right directions in the outer frame 5;

[0042] Specifically, refer to Figure 2Each detection assembly 6 includes a plurality of adjustment blocks 61, a connecting column 62 fixed to the adjustment blocks 61, a mounting seat 63 fixed to the connecting column 62, a docking seat 64 detachably connected to the mounting seat 63, and a pressure head 65 fixedly connected to the docking seat 64, wherein the plurality of adjustment blocks 61 are arranged in the outer frame 5 and are equally spaced along the front-rear direction in the outer frame 5;

[0043] The pressure heads 65 mentioned above are arranged compactly with each other in the initial state. The pressure heads 65 in this arrangement can provide a more concentrated load for the material to be tested, so as to be suitable for the bending performance of the material to be tested under high stress concentration.

[0044] During use, the material to be tested is first divided into multiple samples, and the first sample is placed on two groups of support seats 3. Then, the hydraulic cylinder 4 is started, and the driving control outer frame 5 of the hydraulic cylinder 4 is used to drive the detection component 6 to move downward. Through multiple groups of compactly arranged pressure heads 65, a concentrated load perpendicular to the surface of the first sample is applied to cause the material to bend and deform, and data 1 is obtained through the control system.

[0045] Further, see Figure 3-Figure 5 Each detection assembly 6 is provided with a first adjustment mechanism 7, which is used to control the multiple adjustment blocks 61 to be spread out at equal distances along the front and rear directions of the outer frame 5. The first adjustment mechanism 7 includes a bidirectional threaded rod 71 rotatably arranged in the outer frame 5, wherein the front and rear adjustment blocks 61 are both threadedly sleeved on the bidirectional threaded rod 71, and the remaining adjustment blocks 61 are movably sleeved on the bidirectional threaded rod 71. A connecting rod mechanism 72 is also provided between the multiple adjustment blocks 61, and the connecting rod mechanism 72 includes a hinged rod 721 rotatably arranged on each adjustment block 61, and the center of each hinged rod 721 is The two adjacent sets of hinged rods 721 are rotationally connected to the adjustment block 61 through the rotation shaft 1 722, and the front and rear sets of adjustment blocks 61 move in opposite directions respectively when the bidirectional threaded rod 71 rotates. The multiple sets of adjustment blocks 61 are controlled to be spread out equidistantly along the front and rear directions in the outer frame 5 under the cooperation of the connecting rod mechanism 72, so that the originally compactly arranged pressure heads 65 can be spread out equidistantly along the front and rear directions of the outer frame 5, thereby applying multi-point pressure to the material to be tested, providing other different stress distribution conditions, and thus improving the accuracy of the test data.

[0046] Reference Figure 6-Figure 7At least three groups of track plates 73 are also provided in the outer frame 5, and the three groups of track plates 73 are respectively arranged above the detection component 6, wherein a slider 611 is fixed on each group of adjustment blocks 61, and a slide groove 731 for limiting the sliding of the slider 611 is opened on each group of track plates 73. When the adjustment block 61 is unfolded along the front and rear direction in the outer frame 5 as the bidirectional threaded rod 71 rotates, the slider 611 can slide in the corresponding slide groove 731, thereby providing a limit for the unfolding of the adjustment block 61, making the unfolding process of the adjustment block 61 more stable.

[0047] During use, by controlling the rotation of the bidirectional threaded rod 71 and limiting the adjustment block 61 by the slider 611, the front and rear groups of adjustment blocks 61 are moved away from each other, and through the rotation connection between the hinge rods 721, the multiple groups of adjustment blocks 61 are controlled to be unfolded along the front-to-back direction in the outer frame 5, thereby driving the connecting column 62, the mounting seat 63, the docking seat 64 and the pressure head 65 to move together, so that the originally compactly arranged pressure head 65 is unfolded equidistantly along the front-to-back direction of the outer frame 5;

[0048] At this time, the second sample is placed on two groups of support seats 3, and the outer frame 5 is controlled by starting the hydraulic cylinder 4 to drive the unfolded multiple groups of pressure heads 65 to move downward, and apply loads perpendicular to multiple positions in front and behind the surface of the second sample to cause the material to bend and deform, and obtain data 2 through the control system.

[0049] Further, refer to Figure 10-11 The left and right track plates 73 are both limitedly slidably arranged in the outer frame 5, the middle track plate 73 is fixed in the outer frame 5, and a second adjustment mechanism 9 is provided between the left and right track plates 73. The second adjustment mechanism 9 is used to control the adjustment block 61 to be spread out at equal distances along the left and right directions in the outer frame 5. A cross bar 732 is fixed in the outer frame 5, and the left and right track plates 73 are both movably sleeved on the cross bar 732. When the left and right track plates 73 move, the cross bar 732 can provide a stable supporting force for the track plates 73;

[0050] Specifically, the second adjustment mechanism 9 includes an adjustment plate 91 disposed in the outer frame 5 and two sets of guide grooves 92 symmetrically provided on the adjustment plate 91. A guide block 93 is slidably provided in each set of guide grooves 92. The guide blocks 93 are respectively fixed on the left and right sets of track plates 73. When the adjustment plate 91 moves, the left and right sets of track plates 73 can be moved closer to or farther from each other through the cooperation of the guide grooves 92 and the guide blocks 93.

[0051] Two groups of connecting plates 911 are symmetrically fixed on the left and right sides of the adjusting plate 91. A threaded screw 912 is connected to one group of connecting plates 911 through a thread. One end of the threaded screw 912 is rotatably arranged in the outer frame 5, and the other end of the threaded screw 912 passes through the outside of the outer frame 5 and is fixed with a second handle 913. By controlling the rotation of the threaded screw 912, the adjusting plate 91 can be driven to move in the outer frame 5, so that the left and right groups of track plates 73 can move along the left and right directions in the outer frame 5, thereby driving the adjusting block 61 to continue to expand along the left and right directions of the outer frame 5, so that the pressure head 65 can achieve a more uniform pressure distribution on the material to be tested, and then more comprehensively evaluate the performance of the material, thereby further improving the flexibility and adaptability of the equipment when performing strength testing, and by applying loads in multiple directions, it can further simulate more complex actual working conditions, such as the influence of multiple forces such as long-term backlog, which helps to improve the accuracy of the test data;

[0052] Among them, a limiting rod 914 is movably passed through another set of connecting plates 911 , and both ends of the limiting rod 914 are fixed in the outer frame 5 . The limiting rod 914 is used to limit the movement of the adjusting plate 91 .

[0053] During use: by controlling the second handle 913 to rotate, the threaded screw 912 rotates, and the limiting action of the limiting rod 914 allows the adjustment plate 91 to move in the outer frame 5. While the adjustment plate 91 moves, the guide block 93 slides in the guide groove 92. At this time, the left and right groups of track plates 73 can slide on the surface of the cross bar 732 and move away from each other. When the left and right groups of track plates 73 move away from each other, the left and right groups of detection components 6 can be driven away from each other, so that the pressure head 65 can continue to expand along the left and right direction of the outer frame 5 again. The expanded state can be referred to Fig.12 ;

[0054] At this time, the third sample is placed on two groups of support seats 3. The outer frame 5 is controlled by starting the hydraulic cylinder 4 to drive the fully expanded multiple groups of pressure heads 65 to move downward, and loads are applied to the surface of the third sample in multiple directions such as front, back, left and right to make the material bend and deform. Data three is obtained through the control system. By setting different detection modes, the multiple stress conditions of the filing cabinet in actual use are simulated to obtain multiple groups of data, and analysis and comparison are performed to further improve the accuracy of the detection data.

[0055] Specifically, refer to Figure 8-Figure 9, one end of each set of bidirectional threaded rods 71 ​​is provided with a driving mechanism 8, each set of driving mechanism 8 includes a worm wheel 81 fixed at one end of the bidirectional threaded rod 71 and a worm 82 meshingly connected with the worm wheel 81, a shaft 83 is rotatably connected in the outer frame 5, and the shaft 83 and the worm 82 are connected through a spline shaft, wherein one end of the shaft 83 passes through the outside of the outer frame 5 and is fixed with a first handle 831, and the shaft 83 drives the worm 82 to rotate by controlling the first handle 831 to rotate, thereby controlling the worm wheel 81 to drive the corresponding bidirectional threaded rod 71 to rotate, which is convenient for operators to operate;

[0056] When the left and right groups of track plates 73 approach or move away from each other, the adjustment block 61 can be expanded along the left and right directions within the outer frame 5, and similarly, the left and right groups of bidirectional threaded rods 71 ​​will also move with the expansion of the adjustment block 61. Therefore, a support frame 821 is rotatably sleeved outside each group of worm gears 82, and the end of the support frame 821 away from the worm gear 82 is fixed to the track plate 73, so that the worm gear 82 can move with the movement of the corresponding bidirectional threaded rod 71 and can always maintain engagement with the worm wheel 81.

[0057] During use: when it is necessary to control multiple groups of pressure heads 65 to expand along the front and rear directions of the outer frame 5, the first handle 831 is held to control the rotation of the shaft 83, so that the shaft 83 drives the worm 82 to rotate, and the corresponding worm wheel 81 is controlled to rotate, so that the bidirectional threaded rod 71 rotates and drives multiple groups of adjustment blocks 61 to expand. When the multiple groups of pressure heads 65 are expanded along the left and right directions of the outer frame 5, the left and right groups of track plates 73 move away from each other while driving the support frame 821 to move, and the corresponding worm 82 is driven to move through the support frame 821, so that the worm 82 always remains in mesh with the worm wheel 81.

[0058] Reference Fig.12 The docking seat 64 and the mounting seat 63 are detachably connected by a bolt 641 and a nut 642. The docking seat 64 and the mounting seat 63 are provided with corresponding screw holes, wherein the bolt 641 is threadedly connected in the screw hole, and the nut 642 is threadedly sleeved on the bolt 641. By providing a detachable connection between the mounting seat 63 and the docking seat 64, it is possible to conveniently replace pressure heads 65 of different types or sizes according to different detection needs to adapt to a variety of materials and detection requirements.

[0059] During use: by rotating the nut 642 to disengage the nut 642 from the bolt 641, and then rotating the bolt 641 to disengage the bolt 641 from the corresponding screw hole, the docking seat 64 and the mounting seat 63 can be disassembled, and then the pressure head 65 can be replaced.

[0060] Reference Fig.14A connecting plate 51 is fixed on the outer frame 5, and a support rod 52 runs through the connecting plate 51. Both ends of the support rod 52 are fixed on the detection platform 2. When the hydraulic cylinder 4 controls the outer frame 5 to move up and down, the cooperation between the connecting plate 51 and the support rod 52 is used to provide a limit for the outer frame 5.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
