[0018] The present disclosure provides a steel material property testing device comprising a first support plate, a second support plate, a first optical axis, a third support plate, a fourth support plate, a tension sensor, a three-jaw clamp, and a hydraulic cylinder. The first optical axis is mounted between the opposing surfaces of the first and second support plates and is used to determine the relative positions of the first and second support plates and to provide a guide and support function. The third support plate is located between the opposing surfaces of the first and second support plates and is slidably mounted on the first optical axis to support and mount one of the two three-jaw clamps.

The fourth support plate 5 is located between the opposing surfaces of the third support plate 4 and the second support plate 2. The plane of the fourth support plate 5 is parallel to the plane of the first support plate 1. The tension sensor 6 is mounted between the opposing surfaces of the fourth support plate 5 and the first support plate 1 along the height direction of the first optical axis 3. The three-jaw clamp 7 is mounted on the opposing surfaces of the fourth support plate 5 and the third support plate 4, respectively, for clamping the ends of the steel material. The hydraulic cylinder 8 is installed on the second support plate 2 along the height direction of the first optical axis 3 . The movable end of the hydraulic cylinder 8 is movably disposed through the second support plate 2 and connected to the third support plate 4 .

[0037] The present invention provides a steel material performance testing device, comprising a first support plate 1, a second support plate 2, a first optical axis 3, a third support plate 4, a fourth support plate 5, a tension sensor 6, a three-jaw clamp 7, and a hydraulic cylinder 8. The first optical axis 3 is mounted between the opposing surfaces of the first support plate 1 and the second support plate 2, and is used to determine the relative position of the first support plate 1 and the second support plate 2 and to provide a guiding support. The third support plate 4 is located between the opposing surfaces of the first support plate 1 and the second support plate 2 and is slidably mounted on the first optical axis 3, supporting and mounting one of the two three-jaw clamps 7. The fourth support plate 5 is located between the opposing surfaces of the third support plate 4 and the second support plate 2, supporting and mounting the other of the two three-jaw clamps 7. The tension sensor 6 is mounted between the opposing surfaces of the fourth support plate 5 and the first support plate 1 along the height direction of the first optical axis 3, for performing tension testing.

The hydraulic cylinder 8 is mounted on the second support plate 2 along the height direction of the first optical axis 3 to provide driving force. The movable end of the hydraulic cylinder 8 is movably disposed through the second support plate 2 and connected to the third support plate 4 to drive the third support plate 4 to perform linear motion.

[0038] During use, the hydraulic cylinder 8 is controlled to work, which can drive the third support plate 4 to move along the axial direction of the first optical axis 3. The distance between the two three-jaw clamps 7 is then changed, so that the steel can be placed between the two three-jaw clamps 7 and then clamped and fixed by the two three-jaw clamps 7. Then, the hydraulic cylinder 8 is controlled to work again, so that the two three-jaw clamps 7 are moved away from each other, and the clamped steel can be stretched. At this time, the tension sensor 6 can detect the tension on the steel in real time, and then judge the tensile properties of the steel. In addition, since the hydraulic cylinder 8 can provide a large output force, it can avoid the phenomenon of stopping when the steel is stretched, thereby ensuring the smooth progress of the detection work.
