[0002] The requirements for mechanical property tests of metal materials are also constantly improving, among which the operational safety of the testing process is the most important. The tensile strength is the critical value of the transition of the metal from uniform plastic deformation to local concentrated plastic deformation. It is also the maximum bearing capacity of the metal under static tension. The tensile strength characterizes the resistance to the maximum uniform plastic deformation of the material. Before the tensile specimen is subjected to the maximum tensile stress, the deformation is uniform, but after exceeding it, the metal begins to neck, that is, concentrated deformation occurs. For brittle materials with no (or very small) uniform plastic deformation, it reflects the fracture resistance of the material. Therefore, when metal materials are produced, the quality of the metal materials needs to be tested.

[0022] Specifically, a guide rod 5 is provided on one side of the support column 4, and a moving seat 6 is slidably mounted on the surface of the guide rod 5. The outer surface of the mounting plate 7 is connected to a limit ring 8, and the outer surface of the limit ring 8 is rotatably connected to the inner wall of the moving seat 6. The hydraulic cylinder 3 is fixedly mounted on the top of the mounting housing 2, and the extended end of the hydraulic cylinder 3 is connected to the top center position of the mounting plate 7. An upper fixed claw 9 for fixing one end of the metal material is installed at the bottom of the mounting plate 7. A driven gear ring 10 is connected to the top of the mounting plate 7, and a servo motor 11 is embedded on one side of the mounting plate 7 and located at the bottom of the moving seat 6. The output end of the servo motor 11 is transmission-connected to the driven gear ring 10 through a transmission gear.

[0023] Among them, the guide rod 5 plays a guiding and limiting role for the moving seat 6, thereby improving the stability of the moving and stretching of the moving seat 6. The mounting plate 7 is a component for loading the upper fixed claw 9. The limit ring 8 is a limiting structure for the mounting plate 7 to rotate inside the moving seat 6. The hydraulic cylinder 3 is an important structure for the control device to perform tensile testing. The upper fixed claw 9 and the lower fixed claw 23 are respectively chucks for clamping and fixing the two ends of the metal material. The servo motor 11 is a driving component for rotating the mounting plate 7, thereby controlling the mounting plate 7 to rotate, thereby detecting the twisting state of the metal material. The driven gear ring 10 is a transmission structure driven by the servo motor 11.

[0024] The protection assembly includes: a guide rail 22 connected to the bottom of the bearing base 1, and a connecting plate 15 connected to both sides of the arc-shaped protective tube 14; wherein the connecting plate 15 is slidably connected to the surface of the guide rail 22, and an electric push rod 21 is connected to the top of the bearing base 1, and the extended end of the electric push rod 21 is movably engaged with the outer surface of the arc-shaped protective tube 14. A storage groove 16 is provided inside the arc-shaped protective tube 14, and assembly grooves 17 connected to the storage groove 16 are provided on both sides of the top of the arc-shaped protective tube 14, and an arc-shaped limit strip 19 is connected to the bottom end of the extended protective plate 18, and the arc-shaped limit strip 19 is movably connected to the inner wall of the storage groove 16 through the assembly groove 17.

[0025] Furthermore, the guide rail 22 is a structure that serves as a guide and limit when the arc protective tube 14 moves, thereby ensuring the stability of the structure.

[0028] During the test, when the hydraulic cylinder 3 contracts, the mounting plate 7 follows the moving seat 6 and cooperates with the guide rod 5 to move upward, driving the metal material to stretch and perform a stretch test, and cooperates with the servo motor 11 to drive the driven gear ring 10, so that the mounting plate 7 rotates, driving the metal material to twist and perform a twist test;

[0029] During replacement and maintenance, the movable seat 6 is pulled up to the top by the hydraulic cylinder 3, and the clamping seat 20 on the outer surface of the extension guard plate 18 is disconnected from the clamping joint 13 connected to the end of the telescopic rod 12. At the same time, the extension guard plate 18 is rotated outward so that the arc-shaped limiting strip 19 at the bottom end of the extension guard plate 18 is moved out of the assembly groove 17 to replace the extension guard plate 18. Similarly, the extension guard plate 18 can be assembled inside the storage groove 16.
