Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] The utility model provides the following technical solutions:

[0027] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a bending device for building material steel bars, comprising a base 1, a supporting leg 2 fixedly connected to the bottom of the base 1, an adjusting mechanism 3 provided on the top of the base 1, and a bending mechanism 4 provided on the left side of the top of the base 1;

[0028] The adjustment mechanism 3 includes a fixed frame 31, which is fixedly connected to the right side of the top of the base 1. The bottom of the fixed frame 31 is equidistantly connected to the first rotating shaft 32 near the back. The surface of the first rotating shaft 32 is fixedly connected to the first clamping wheel 33. The surface of the first rotating shaft 32 is fixedly connected to the worm gear 34 near the top. The top right side of the fixed frame 31 is fixedly connected to the back. The output end of the first motor 35 is fixedly connected to the worm 36. The top left side of the fixed frame 31 is fixedly connected to the back. A fixing plate 37 is fixedly connected. The fixed frame 31 has symmetrical openings on the left and right sides. Through hole 38, a sliding frame 39 is connected to the fixed frame 31 for front and rear sliding sliding. The bottom of the sliding frame 39 is connected to the second rotating shaft 311 for equidistant rotation near the back. The second clamping wheel 312 is fixedly connected to the surface of the second rotating shaft 311. A first fixed sleeve 313 is fixedly connected to the top right side of the base 1 near the front. A second motor 314 is fixedly connected to the first fixed sleeve 313. A screw 315 is fixedly connected to the output end of the second motor 314. A threaded sleeve 316 is threadedly connected to the surface of the screw 315. A connecting plate 317 is fixedly connected to the surface of the threaded sleeve 316.

[0029] A hole matching the first rotating shaft 32 is formed on the top of the fixing frame 31 , and the first rotating shaft 32 passes through the surface and is rotatably connected in the hole.

[0030] The worm 36 is meshed with the worm wheel 34 , and the left end of the worm 36 is rotatably connected to the right side of the fixing plate 37 .

[0031] The other end of the connecting plate 317 is fixed to the inner wall of the sliding frame 39 . Since the sliding frame 39 slides in the fixed frame 31 , the threaded sleeve 316 can only move forward and backward along with the screw rod 315 .

[0032] Example 2: Please refer to Figure 5 , and on the basis of embodiment 1, a bending mechanism 4 is further obtained.

[0033] The bending mechanism 4 includes a fixed plate 41, which is fixedly connected to the left side of the top of the base 1. A first fixed rod 42 is fixedly connected to the top of the fixed plate 37. An L-plate 43 is fixedly connected to the surface of the fixed plate 41 near the edge. A second fixed sleeve 44 is fixedly connected to the front of the L-plate 43 near the top. A third motor 45 is fixedly connected inside the second fixed sleeve 44. A first gear 46 is fixedly connected to the surface of the output shaft of the third motor 45. A third rotating shaft 47 is provided near the rear end of the top of the L-plate 43. A second gear 48 is fixedly connected to the surface of the third rotating shaft 47 near the top. A turntable 49 is fixedly connected to the bottom of the turntable 49 near the edge. A second fixed rod 411 is fixedly connected to the bottom of the turntable 49 near the edge.

[0034] A hole matching the third rotating shaft 47 is formed on the top of the L-plate 43 , and the surface of the third rotating shaft 47 passes through and is rotatably connected in the hole.

[0035] The first gear 46 is meshed with the second gear 48 , and the diameter of the first gear 46 is smaller than that of the second gear 48 , so the first gear 46 drives the second gear 48 to rotate slowly.

[0036] In actual operation, when this device is used, the steel bar is placed in the through hole 38, and then the second motor 314 is started to rotate the screw 315. The rotation of the screw 315 drives the sliding frame 39 to slide back and forth in the fixed frame 31, so that the second clamping wheel 312 and the first clamping wheel 33 clamp the steel bar. Then, the first motor 35 is started to rotate the worm 36. The rotation of the worm 36 rotates the worm wheel 34, thereby rotating the first rotating shaft 32. The rotation of the first rotating shaft 32 rotates the first clamping wheel 33, thereby moving the steel bar clamped by the first clamping wheel 33 and the second clamping wheel 312 to the left. This process does not require the staff to carry the steel bar, thereby reducing the workload of the staff.

[0037] Insert the steel bar between the first fixing rod 42 and the second fixing rod 411, then start the third motor 45 to rotate the first gear 46, which drives the second gear 48 to rotate slowly, thereby rotating the third rotating shaft 47, and the third rotating shaft 47 drives the turntable 49 to rotate, thereby causing the second fixing rod 411 to perform a circular motion, thereby bending the steel bar.

[0038] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
