Description

Technical Field

[0001] This utility model relates to the field of materials science and engineering technology, specifically to a metal material bending strength testing platform. Background Technology

[0002] In the fields of materials science and engineering, metallic materials, due to their high strength and high toughness, are widely used in key industries such as construction, machinery manufacturing, and aerospace. The bending strength of metallic materials, as a core indicator for evaluating their structural load-bearing capacity and operational safety, directly determines the performance and service life of the final product. Therefore, accurate bending strength testing of metallic materials is a crucial step in product development, quality inspection, and production control.

[0003] A search revealed existing technology (application number: CN202321019892.0), which describes "an experimental platform for testing the bending strength of stone." This utility model includes a base and a testing platform. A waste collection trough is located inside the center of the testing platform. Two sets of first rotary drive components are symmetrically arranged on one side of the bottom of the waste collection trough. A crushing roller is movably mounted at the output end of each first rotary drive component, and the crushing roller is movably installed at the bottom of the waste collection trough. A discharge port is located at the bottom of the waste collection trough. This utility model uses the two sets of first rotary drive components to drive the crushing roller to rotate, causing the two sets of crushing rollers to work together to crush stone fragments. The crushed stone fragments fall into the conveying trough through the discharge port, and then a second rotary drive component drives a screw rod to rotate, causing the screw rod to discharge the fragments from the conveying trough through the discharge port. This solves the problem of inconvenient cleaning of stone fragments from the surface of the experimental platform for testing the bending strength of stone, making the platform more convenient to use.

[0004] However, while existing technologies have improved overall cleanliness, they still have some shortcomings: they cannot adapt to test materials of different sizes, and they cannot freely change the test position, etc. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a metal material bending strength testing platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal material bending strength testing platform, comprising: a support, with legs installed at the four corners of the bottom, and a through groove in the middle of the support, with sliding grooves on both sides of the inner wall of the through groove; a support plate, located above the support, fixed to the top of the support by rectangular posts at the four corners of the bottom, with a rectangular groove in the middle of the support plate, the rectangular groove penetrating one side of the support plate, and strip grooves on both sides of the inner wall of the rectangular groove, with a baffle fixed to one end of the outer side of the rectangular groove by bolts; and a collection box, placed on one side of the top of the support plate, with a partition inside the collection box and a cover plate on the top of the collection box.

[0032] Example 1:

[0033] like Figures 1 to 5 As shown, this embodiment provides a metal material bending strength testing platform, comprising: a support 1, with legs installed at the four corners of the bottom, and a through groove 100 in the middle of the support 1, with sliding grooves 101 on both sides of the inner wall of the through groove 100; a support plate 2, located above the support 1, fixed to the top of the support 1 by rectangular posts at the four corners of the bottom, with a rectangular groove 200 in the middle of the support plate 2, the rectangular groove 200 penetrating one side of the support plate 2, and strip grooves 201 on both sides of the inner wall of the rectangular groove 200, with a baffle fixed to one end of the outer side of the rectangular groove 200 by bolts; and a collection box 3, placed on one side of the top of the support plate 2, with a partition inside the collection box 3, and a cover plate installed on the top of the collection box 3.

[0034] In this embodiment, the clamping device and the testing device constitute a metal material bending strength testing platform according to this application.

[0035] It should also be noted that the metal material bending strength testing stand in this application can be a general-purpose metal material bending strength testing stand, a high-precision metal sheet bending strength testing stand, a high-temperature environment metal material bending strength testing stand, etc. Figure 1 In this embodiment, a general-purpose metal material bending strength testing stand is used as an example for description. Of course, other types of metal material bending strength testing stands can also adopt similar structures, which will not be described in detail below.

[0036] Understandable Figure 1 This illustration only schematically shows some components of a metal material bending strength testing bench; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, a bending strength testing bench for metallic materials can also include, compared to... Figure 1 More or fewer parts.

[0037] In this embodiment, the support 1 is made of Q235 steel and is rectangular in shape. There are four legs made of 45# steel, which are welded to the four corners of the bottom of the support 1. The through groove 100 is rectangular. There are two sliding grooves 101, symmetrically located on the inner walls of the left and right sides of the through groove 100, and both are rectangular. The support 1 achieves overall stable support through its four bottom legs. The through groove 100 provides installation and movement space for the clamping device, and the sliding grooves 101 provide sliding guidance for the rectangular plate of the clamping device. This ensures the test platform is placed stably, providing the basic conditions for the installation and operation of the clamping device and ensuring that the clamping device can move along a fixed trajectory.

[0038] Specifically, a clamping device is also provided above the support 1, and the clamping device is located below the support plate 2. A testing device is also provided on the support plate 2.

[0039] In this embodiment, the clamping device is primarily made of Q235 steel and is located in the space between the upper surface of the support 1 and the lower surface of the support plate 2; the testing device is primarily made of 45# steel and is located on the lower surface of the support plate 2. The clamping device clamps and fixes the metal material above the support 1, while the testing device performs a bending strength test on the fixed metal material on the support plate 2. The two devices work together in different positions. Clearly defining the installation positions of the clamping device and the testing device avoids interference between their movements and ensures the orderly execution of the process of fixing the metal material before testing.

[0040] Specifically, the testing device includes: a sliding block 41 that slides within a rectangular groove 200, with rectangular blocks 42 fixed to the middle of both sides of the sliding block 41; rectangular blocks 42 that slide within a strip groove 201, with a button 420 provided on one set of rectangular blocks 42; and a cylindrical rod 43 that slides through the middle of the sliding block 41, with a placement box 44 fixed to the top of the cylindrical rod 43 and a pressure head installed at the bottom of the cylindrical rod 43.

[0041] In a preferred embodiment, the sliding block 41 is cuboid in shape and made of 45# steel; two rectangular blocks 42, also made of 45# steel, are welded to the middle of the left and right sides of the sliding block 41 respectively; the button 420 is made of ABS plastic, cylindrical in shape, and is mounted on the upper surface of one side of the rectangular block 42; the cylindrical rod 43 is made of 40Cr steel and cylindrical in shape; the placement box 44 is made of Q235 steel, cuboid in shape, and welded to the top of the cylindrical rod 43; the pressure head is made of hard alloy, hemispherical in shape, and connected to the bottom of the cylindrical rod 43. The sliding block 41 drives the rectangular blocks 42 to slide within the rectangular groove 200 and the strip groove 201, adjusting the position of the testing device; the button 420 is used to fix the position of the sliding block; the cylindrical rod 43 slides in the middle of the sliding block 41, driving the pressure head to press down on the metal material; weights are added to the placement box 44 to provide pressure to the pressure head. The test device position can be flexibly adjusted, allowing for testing of different parts of the metal material. By applying pressure with weights, bending stress can be simulated, thus completing the basic operation of bending strength testing.

[0042] Example 2:

[0043] Based on Example 1, in order to enable the device to be quickly reset after testing, a telescopic rod 46 and a spring 47 are provided on the connecting plate 45;

[0044] Specifically, the testing device also includes: a connecting plate 45, fixed to the bottom of the cylindrical rod 43, and telescopic rods 46 are respectively provided at the four corners of the top of the connecting plate 45, with the top of the telescopic rods 46 fixed to the bottom of the sliding block 41; and four sets of springs 47, which are sleeved on the outside of the telescopic rods 46, with the bottom of the springs 47 fixed to the connecting plate 45 and the top fixed to the bottom of the sliding block 41.

[0045] In this embodiment, the connecting plate 45 is made of Q235 steel, is rectangular, and is welded to the bottom of the cylindrical rod 43. There are four telescopic rods 46, made of 45# steel, consisting of an inner rod and an outer cylinder, respectively fixed to the top four corners of the connecting plate 45 and the bottom four corners of the sliding block 41. There are four springs 47, made of 65Mn steel, respectively fitted onto the outside of the four telescopic rods 46, with their ends welded to the top of the connecting plate 45 and the bottom of the sliding block 41. When the cylindrical rod 43 is pressed down, it causes the connecting plate 45 to move downwards, the telescopic rods 46 to extend, and the springs 47 to stretch. After the test, the springs 47 rebound, causing the connecting plate 45 and the cylindrical rod 43 to reset, and the telescopic rods 46 to retract. The elasticity of the springs 47 enables the automatic reset of the cylindrical rod 43, eliminating the need for manual operation and improving testing efficiency. The telescopic rods 46 ensure that the springs 47 do not shift during extension and retraction, guaranteeing reset stability.

[0046] Specifically, the bottom of button 420 is slidably connected to the slot opened at the top of rectangular block 42, and the top of button 420 is slidably connected to the circular slot above strip slot 201. There are several sets of circular slots, which are evenly distributed on the top of support plate 2.

[0047] With this configuration, the top slots of the rectangular block 42 are cylindrical and evenly distributed on the top of the support plate 2, arranged along the length of the strip groove 201. The bottom of the button 420 slides within the top slot of the rectangular block 42, and its top can be inserted into the circular groove on the top of the support plate 2. When the top of the button 420 is inserted into the circular groove, it restricts the sliding of the rectangular block 42 and the sliding block 41, thus fixing the position of the testing device. Through multiple evenly distributed circular grooves, the testing device can be fixed in different positions to meet the needs of different testing points for metal materials. The fixing method is simple, reliable, and easy to adjust quickly.

[0048] Example 3:

[0049] Based on Example 2, in order to improve the workpiece replacement efficiency, a clamping device is provided on the support 1.

[0050] Specifically, a spring 421 is provided inside the button 420. The bottom of the spring 421 is fixed to the inside of the rectangular block 42, and the top of the spring 421 is fixed to the top of the inner wall of the button 420.

[0051] The spring 421 is made of 65Mn steel, with its bottom welded to the bottom of the slot inside the rectangular block 42 and its top welded to the top of the inner wall of the button 420. When the button 420 is pressed, the spring 421 is compressed, and the top of the button 420 retracts into the slot of the rectangular block 42, allowing the sliding block 41 to move. When the button 420 is released, the spring 421 rebounds, pushing the top of the button 420 out and inserting it into the circular groove of the support plate 2, fixing the position of the sliding block 41. The elasticity of the spring 421 enables the button 420 to automatically pop out and reset, simplifying the operation steps for adjusting the position of the testing device and improving operational convenience.

[0052] Specifically, the clamping device includes: two sets of rectangular plates 51, both of which can slide in the sliding groove 101; two sets of clamps 52 located above the rectangular plates 51, which are fixed to the top of the rectangular plates 51 by rectangular posts at both ends of the bottom; and a bidirectional threaded rod 53 that threadedly connects the two sets of rectangular plates 51 through the thread. One end of the bidirectional threaded rod 53 is rotatably connected to one side of the inner wall of the through groove 100, and the other end is fixed with a cylindrical shaft. The cylindrical shaft passes through one side of the support 1, and a knob is installed on the outer end of the cylindrical shaft.

[0053] In this embodiment, there are two rectangular plates 51, made of Q235 steel; two clamps 52, made of 45# steel, which are fixed to the top of the rectangular plates 51 by welding rectangular columns at both ends of the bottom; and a bidirectional threaded rod 53, made of 40Cr steel, which passes through and threadedly connects the two sets of rectangular plates 51. One end is rotatably connected to the inner wall of one side of the through groove 100, and the other end is fixed to a cylindrical shaft that passes through the side wall of the support 1. A knob is fixed to the outer end of the cylindrical shaft. Rotating the knob drives the cylindrical shaft and the bidirectional threaded rod 53 to rotate. The bidirectional threaded rod 53 drives the two sets of rectangular plates 51 to move closer or further apart along the sliding groove 101 through threaded transmission, thereby driving the two sets of clamps 52 to move closer or further apart, realizing the clamping and loosening of metal materials of different widths. The transmission of the bidirectional threaded rod enables flexible adjustment of the distance between the two sets of clamps, which can adapt to metal materials of different widths, clamp firmly, and solve the problem that existing equipment cannot adapt to materials of different sizes.

[0054] In actual use, the user places the metal material to be tested in one of the clamps 52, and rotates the knob at one end of the circular shaft of the bidirectional threaded rod 53. The bidirectional threaded rod 53 rotates, causing the two sets of rectangular plates 51 and the clamps 52 above them to move closer or further apart, clamping the other end of the test material. This design can clamp metal materials of different sizes without changing the clamps 52, improving testing efficiency. Pressing the button 420 causes the spring 421 to retract, causing the button 420 to retract into the support plate 2. The testing device is then moved to the appropriate position (i.e., to the corresponding circular groove). 421, without force, springs back, causing button 420 to spring into the circular groove at the top of support plate 2, thus fixing the device. Then, the cover of collection box 3 is opened, and a portion of the weight is taken out and placed in placement box 44. The weight presses the cylindrical rod 43, which slides on sliding block 41. At this time, telescopic rod 46 extends, spring 47 is stretched, and the pressure head at the bottom of cylindrical rod 43 presses down on the top of the material, removing the weight. Button 420 is pressed to move the testing device, adding weights of different weights to test the remaining parts of the material. This design allows for rapid measurement of multiple parts of the material, making the test more comprehensive. The partition inside collection box 3 divides the space into different sized sections, allowing for placement according to weight size, making collection and retrieval clearer and more convenient.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
