[0002] At present, when inspecting the quality of steel bars, the inspection is single, only the bending resistance performance of the steel bars can be detected, and other performances of the steel bars cannot be detected, so the practicability is relatively low.

[0003] The "a steel bar quality inspection device" disclosed in the Chinese utility model patent (application number: CN220508683U), which relates to the technical field of steel bar quality inspection, includes a sliding seat and a base of a steel bar anti-bending and folding testing machine. There are two circular rod grooves penetrating through the sliding seat. The front end of the sliding seat is rotatably connected with a rotating rod. The rear end of the upper surface of the base is fixedly connected with a stop bar, and two limiting rods are fixedly connected to the stop bar. The front end of the upper surface of the base is fixedly connected with two fixed seats, and a rotating part is rotatably connected between the two fixed seats.

When the sliding seat moves to the frontmost end, the rotating part can be held and rotated, and the rotation of the rotating part drives the sliding seat to flip. A steel bar recovery cylinder is placed in front of the base. The sliding seat that moves forward and flips can facilitate the removal of the bent steel bars and also facilitate the placement of new steel bars to be inspected into the current limiting mechanism above the sliding seat.

[0052] Furthermore, as Figures 1-4 shown, the detection assembly 9 is composed of a shear resistance detection mechanism and a bending resistance detection mechanism.

[0056] The use process of the quality detection device provided by the present utility model is as follows:

[0057] Place the steel bar between two corresponding lower arc-shaped members 3. First, perform shear performance detection on the steel bar. The piston rod of the hydraulic cylinder 901 drives the connecting plate 903 to move downward. The connecting plate 903 drives the cutter 904 and the pressing blocks 905 to move downward at the same time. When the pressing blocks 905 move into the slots, they drive the limiting member 503 to move downward. The limiting member 503 drives the upper arc-shaped member 501 to move downward until the rubber layer 4 inside it contacts the steel bar. As the cutter 904 continues to move downward, the first spring 504 is compressed, and the steel bar is fixed more firmly. The cutter 904 can continue to cut the steel bar to perform shear performance detection. After the shear performance detection is completed, the hydraulic cylinder 901 resets. Under the action of the reset of the first spring 504, the upper arc-shaped member 501 is separated from the lower arc-shaped member 3. Move the steel bar so that the steel bar moves out of the reset range of the upper arc-shaped member 501. Control the electric slide table 902 to work. The transmission block of the electric slide table 902 drives the hydraulic cylinder 901 to move, so that the cutter 904 moves to directly above the card slot. The piston rod of the hydraulic cylinder 901 drives the cutter 904 to move downward until it contacts the card slot. The cutter 904 continues to move downward. In cooperation with the slide rod 908, the pressing plate 906 moves downward until it contacts the steel bar. As the cutter 904 continues to move downward, the cutter 904 is completely engaged with the card slot, which can cause the pressing plate 906 to press the steel bar downward, realizing the bending performance detection of the steel bar. And when the steel bar is subjected to bending performance detection, the bent part of the steel bar can push the top plate 705 downward. In cooperation with the positioning plate 703 and the positioning column 704, the second spring 702 is compressed. After the bending performance detection is completed, the detection assembly 9 resets. In cooperation with the reset of the second spring 702, the top plate 705 moves upward to push out the steel bar stuck on the positioning wheel 602, eliminating the need for the tester to pull out the deformed steel bar, facilitating the blanking of the steel bar, and improving the practicability.
