Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 As shown, a steel bar bending device for construction engineering includes a base 1, a movable guiding device 2, and an adaptive bending device 3; the movable guiding device 2 is installed with a mounting frame 21, and a plurality of fixed plates 22 are fixedly installed on one side of the mounting frame 21. A rotating shaft 23 is movably installed through one side of the plurality of fixed plates 22, and a threaded shaft 24 is fixedly installed on one end of the rotating shaft 23. A movable block 25 is threadedly connected to one side of the threaded shaft 24;

[0027] During operation, when the rotating shaft 23 is rotated by a person, the threaded cooperation between the movable threaded shaft 24 and the movable block 25 is conducive to realizing the linear movement of the movable block 25 .

[0028] Furthermore, the adaptive bending device 3 is equipped with a support frame 31, a first hydraulic cylinder 34 is fixedly mounted on the top of the support frame 31, a first plunger 35 is movably mounted on the output end of the first hydraulic cylinder 34, a bending arm 33 is hinged on the top of the first plunger 35, and one side of the bending arm 33 is hinged to the support frame 31;

[0029] During operation, when the first hydraulic cylinder 34 is driven to work, the first plunger 35 is moved by converting hydraulic energy into mechanical energy. The first plunger 35 is linked to the bending arm 33 through the hinge at the top end, which is conducive to the bending arm 33 to move in a circle with the hinge of the support frame 31 as the axis.

[0030] Furthermore, the base 1 is installed with a fixing frame 11, a working platform 12 is fixedly installed on the top of the fixing frame 11, a mounting frame 21 is fixedly installed on the top of the working platform 12, and a supporting frame 31 is fixedly installed on the top of the working platform 12;

[0031] During operation, the fixing frame 11 carries and supports the entire structure, ensuring that the entire structure has sufficient stability during use.

[0032] Furthermore, the mounting frame 21 is provided with two grooves, and movable blocks 25 are movably mounted through the grooves. The tops of the two movable blocks 25 are movably mounted with movable wheels 26. The top of the mounting frame 21 is movably mounted with two fixed wheels 27. The bottom of the mounting frame 21 is fixedly mounted with a stepping motor 29. The output end of the stepping motor 29 is fixedly mounted with a guide wheel 28. One side of the guide wheel 28 is movably connected to a steel bar 201.

[0033] During operation, the movable block 25 is limited by the opening of the groove by the mounting frame 21 to ensure that the movable block 25 is horizontally displaced during movement, and the gap between the movable wheel 26 and the fixed wheel 27 is adjusted by the movement of the movable wheel 26 to match steel bars 201 of different specifications. When the stepping motor 29 is working, it drives the guide wheel 28 to transport the steel bars 201, which is conducive to corresponding guidance of the steel bars 201.

[0035] During operation, the top of the support arm 32 contacts the steel bar 201, so that the support arm 32 serves as a support point. When the bending arm 33 moves, it drives the steel bar 201 to bend to one side. Under the installation of the movable roller 36, one side of the steel bar 201 is limited, and the steel bar 201 is bent by interaction.

[0036] Furthermore, a torque motor 39 is fixedly mounted on the top of the support frame 31, and a first sprocket 301 is fixedly mounted on the output end of the torque motor 39.

A worm 304 is fixedly mounted on one side of the second sprocket 303.

[0037] During operation, when the driving torque motor 39 is working, the first sprocket 301 outputs rotational power to the second sprocket 303 through the chain 302, which is conducive to the second sprocket 303 driving the worm 304 to rotate.

[0038] Furthermore, protection chambers 306 are movably mounted on both ends of the worm 304, a worm wheel 305 is transmission-connected to the top of the worm 304, and a movable roller 36 is fixedly mounted on one side of the worm wheel 305;

[0039] During operation, the movable roller 36 is driven to rotate by the cooperation between the worm 304 and the worm wheel 305 . As the movable roller 36 moves, the curvature of the bending of the steel bar 201 can be increased.

[0040] Working principle: In embodiment 1, personnel rotate the rotating shaft 23, and the rotating shaft 23 is limited by the fixed plate 22, and the threaded shaft 24 cooperates with the threaded groove opened by the movable block 25 to convert the rotational motion of the threaded shaft 24 into the linear motion of the movable block 25, so that the movable block 25 drives the movable wheel 26 to move relative to the mounting frame 21, and changes the gap between the movable wheel 26 and the fixed wheel 27 and the guide wheel 28. The gap adjustment is used to adaptively match the steel bar 201, so that one side of the fixed wheel 27 and the movable wheel 26 are tightly fitted with the steel bar 201. At this time, the stepper motor 29 is driven to make the guide wheel 28 rotate, and the rotation of the guide wheel 28 is used to transport the steel bar 201.

[0041] When the worm gear 304 is engaged with the worm gear 305, the worm gear 304 is engaged with the worm gear 305, and the worm gear 305 is engaged with the worm gear 306. When the worm gear 304 is engaged with the worm gear 306, the worm gear 306 is engaged with the worm gear 307.
