Abstract
Description
Technical Field
[0001] This utility model relates to the field of toughness testing technology, and in particular to a toughness testing device for metal material products. Background Technology
[0002] The toughness of a metal product refers to the energy absorbed by the metal product during the process from being subjected to force to fracture. The greater the energy consumed to cause the metal product to fracture, the better the toughness. Consuming energy means that work must be done on the metal material from outside the system, which means that force and displacement are required.
[0003] In existing technologies, the bottom of metal products is generally supported by support members, and the support members have clearance grooves to avoid the pressing head. The span between the support positions on both sides of the clearance groove is constant. However, it is worth considering that when inspecting metal products of different specifications, especially when the thickness of the metal products varies, the span usually needs to be adjusted synchronously according to the standard ratio. Therefore, it is necessary to repeatedly replace support members of different specifications, resulting in a low applicability of the equipment.
[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0022] This specification provides one or more embodiments of a device for testing the toughness of metallic material products, such as... Figure 1 and Figure 2 As shown, it includes a testing platform 1, with several support legs 2 fixedly connected to the bottom of the testing platform 1, two support plates 3 in contact with the top of the testing platform 1, and a testing unit for testing installed on the testing platform 1.
[0023] Support columns 4 are respectively provided on the opposite sides of the two support plates 3. The support columns 4 are equipped with detachable parts that fit the support plates 3. Two first rectangular holes 6 are opened on the testing table 1, and the support columns 4 pass through the corresponding first rectangular holes 6. A fixing plate 5 located below the testing table 1 is fixedly connected to the bottom end of the support column 4, and the width of the fixing plate 5 is smaller than the width of the first rectangular holes 6. A support part 7 is fixedly fitted onto the outside of the support column 4, and the bottom of the support part 7 contacts the top of the testing table 1. A pressing and positioning structure for pressing the fixing plate 5 is installed on the testing table 1. Depending on the specifications of the metal material product to be tested, the operator... The drive support column 4 and support plate 3 move horizontally, adjusting the distance between the two support plates 3. The bottom of the support part 7 contacts the top of the testing table 1, supporting the support column 4 through the support part 7. The pressing and positioning structure presses and positions the fixing plate 5, so that the support column 4 and support plate 3 are fixed relative to the testing table 1. The operator places the metal material product to be tested on the two support plates 3, and the testing unit tests the metal material product. It is convenient to adjust the distance between the two support plates 3 according to the different specifications of the metal material product to be tested, which facilitates the testing of metal material products of different specifications and improves the applicability.
[0024] In embodiments of this utility model, such as Figure 1 and Figure 2As shown, the pressing and positioning structure includes a pressing plate 8 disposed below the testing platform 1. Several first hydraulic telescopic rods 9 are fixedly connected to the testing platform 1, and the telescopic ends of the first hydraulic telescopic rods 9 are fixedly connected to the top of the pressing plate 8. Two second rectangular holes 10 are opened on the pressing plate 8, and the support column 4 passes through the corresponding second rectangular holes 10. The width of the fixing plate 5 is smaller than the width of the second rectangular holes 10. The top of the fixing plate 5 is in contact with the bottom of the pressing plate 8. Two guide strips 12 are fixedly connected to the top of the fixing plate 5. Four guide holes 11 are opened on the pressing plate 8, and the guide strips 12 are located in the corresponding guide holes 11. The operator drives the support column 4 and the support plate 3 to move horizontally relative to the testing platform 1. The support column 4 drives the guide strips 12 through the fixing plate 5 in the guide holes 11. The internal sliding mechanism, through the design of guide holes 11 and guide strips 12, allows the support column 4 and support plate 3 to move smoothly in the horizontal direction. When it is necessary to position the support column 4 and support plate 3, the first hydraulic telescopic rod 9 drives the pressing plate 8 to move downward, so that the pressing plate 8 presses the top of the fixing plate 5, thereby fixing the fixing plate 5 and support column 4 relative to the testing table 1. When it is necessary to remove the support column 4, the first hydraulic telescopic rod 9 drives the pressing plate 8 to move upward, so that the guide strip 12 disengages from the guide hole 11. The operator drives the support column 4 to rotate 90 degrees, so that the fixing plate 5 rotates to be directly below the second rectangular hole 10 and the first rectangular hole 6. The operator drives the support column 4 to move upward, so that the fixing plate 5 passes through the second rectangular hole 10 and the first rectangular hole 6 respectively, thus completing the removal of the support column 4.
[0025] In embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the disassembly and assembly components include a fixing block 13 fixedly installed on the support column 4, and a sliding groove 14 is provided on the side of the fixing block 13 facing the support plate 3.

A positioning hole 16 is provided on the top of the slider 15, and a positioning post 17 is provided in the positioning hole 16. An elastic element adapted to the positioning post 17 is provided on the fixing block 13. The elastic element includes a fixing plate 18 set above the fixing block 13, and the top of the positioning post 17 is fixedly connected to the fixing plate 18. The bottom of the fixing plate 18 and the top of the fixing block 13 are connected by a tension spring 19. When the support plate 3 is twisted and deformed, the operator drives the fixing plate 18 to move upward, and the tension spring 19 is in a stretched state, so that the positioning post 17 is disengaged from the positioning hole 16, releasing the restriction on the position of the slider 15 and the support plate 3. The operator drives the support plate 3 to move, so that the slider 15 is disengaged from the sliding groove 14, thus completing the removal of the support plate 3 and facilitating the replacement of the support plate 3.
[0026] In embodiments of this utility model, such as Figure 1As shown, a support plate 20 is fixedly connected to the top of the support column 4.

When the product is placed on top of the two support plates 3, and the metal product is above the tray 20, the operator drives the two adjacent clamping plates 21 to move so that the two adjacent clamping plates 21 hold the metal product. The operator then drives the two adjacent nuts 24 to rotate relative to the screw 22 so that the two adjacent nuts 24 hold the side plate 23, thereby fixing the clamping plates 21 relative to the tray 20. The clamping plates 21 are used to correct and position the side of the metal product to prevent the metal product from tilting and shaking during the pressing process. The second hydraulic telescopic rod 26 drives the pressing head 27 to move down, and the pressing head 27 can press the metal product to test its toughness.
