However, due to the application characteristics of steel bars, it is different from the mechanical property test of other metal materials. Reverse bending tests are required to determine the reverse bending deformation performance of steel bars after bending plastic deformation and aging.

[0003] In the prior art, steel bars are generally tested through a specific reverse bending device. For example, a steel bar reverse bending device with publication number CN103884584A includes a base plate, a plurality of legs installed on the base plate, a flap installed on the upper part of each leg, and a tray installed on the flap. The above connection forms a steel bar reverse bending structure.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4As shown, the utility model is a reverse bending device for a mechanics room, comprising a mounting plate 1, and a sliding groove 11 is arranged on the top of the mounting plate 1. A fixed seat 2 is fixedly arranged on one side of the mounting plate 1, and fixed disks 21 are arranged on both outer surfaces of the fixed seat 2, and the fixed disks 21 on both sides are mirror-symmetrical about the vertical symmetry plane of the mounting plate 1. A fixed block 22 is arranged inside the fixed seat 2, and a sliding block 6 is slidably arranged on the plane of the fixed block 22, and the top surface shape of the sliding block 6 is concave inward. A moving seat 3 is slidably arranged on the side of the top surface of the mounting plate 1 away from the fixed seat 2, and the bottom of the moving seat 3 is slidably connected to the sliding groove 11. Transmission disks 31 are fixedly arranged on both sides of the surface of the moving seat 3, and the transmission disk 31 is located on the same horizontal line with the corresponding fixed disk 21 on one side. A transmission screw 4 is arranged between the transmission disk 31 and the fixed disk 21 on the same side, and the transmission screw 4 is rotatably connected to the fixed disk 21, and the transmission screw 4 is connected to the inside of the transmission disk 31 through a thread. The internal groove of the movable seat 3 is rotatably provided with a rotating block 32, and the top surface of the rotating block 32 is slidably provided with a sliding block 6, and the shape of the sliding block 6 on the top surface of the rotating block 32 is the same as the shape of the sliding block 6 on the top surface of the fixed block 22. The surface of the movable seat 3 is provided with an inclinometer 33, and the center of the inclinometer 33 coincides with the position of the rotating axis of the rotating block 32. The rotating axis of the rotating block 32 extends from the inside of the fixed seat 2 and is fixedly connected to one end of the pointer 34. The tops of the fixed block 22 and the rotating block 32 are both detachably provided with a fixed cover 5, and the fixed cover 5 is located directly above the sliding block 6.

[0026] When using this reverse bending device for a mechanics room, the bent bending rod is placed in the groove on the top surface of the sliding blocks 6 on both sides, and then the sliding blocks 6 are relatively slid to adapt to the bending rods of different lengths. The rotating block 32 is rotated on the moving seat 3 to adapt to the bending angle of the bending rod, so that the bending rod can contact the sliding block 6 on the rotating block 32.
