[0019] 3. This type of steel bar bending device for construction engineering, after bending, the output shaft of the hydraulic cylinder pushes the cutting blade downward to cut the steel bar. Combined with the two conveyor belts to transport the steel bar, it can continuously bend, cut, and transport the steel bar. In the bending process, it further improves the bending efficiency of the steel bar. At the same time, the slider of the electric guide rail can drive the moving seat to move, thereby adjusting the length of the bending part that needs to be cut, improving adaptability.

When bending the steel bars, multiple steel bars are placed in the corresponding positioning grooves 7 on the two conveyor belts 6 through the clamping and conveying assembly 4. The two servo motors 11 work synchronously, so that the two bidirectional lead screws 9 rotate synchronously. The two external threaded sections of the bidirectional lead screw 9 are threadedly connected to the guide slider 10, so that the guide slider 10 moves along the direction of the guide groove 8, so that the two moving frames 5 move closer to each other. The two conveyor belts 6 can simultaneously convey multiple steel bars and bend multiple steel bars at the same time, which improves the efficiency of steel bar bending.

[0033] Specifically, such as Figure 6 As shown, the bending assembly 3 includes a rotating rod 20 disposed between the base 1 and the top plate 2. Multiple limiting support rods 21, corresponding one-to-one with the positioning grooves 7, are equidistantly arranged on the outer wall of the rotating rod 20.

The output shaft of the hydraulic cylinder 29 is connected to a cutting tool 30. The inner wall of the cutting hole 28 has a cutting groove. When bending, the output shaft of the hydraulic cylinder 29 pushes the cutting tool 30 downward to cut the steel bar. Combined with the conveying of the steel bar by the two conveyor belts 6, bending, cutting, and conveying can be performed continuously. This further improves the bending efficiency of the steel bar. At the same time, the slider of the electric guide rail 26 can drive the movable seat 27 to move, thereby adjusting the length of the bending part to be cut and improving adaptability.

[0035] During operation, this rebar bending device for construction projects bends rebars by placing multiple rebars into corresponding positioning grooves 7 on two conveyor belts 6 via a clamping and conveying assembly 4. Two servo motors 11 work synchronously, causing two bidirectional lead screws 9 to rotate synchronously. The two external threaded sections of the bidirectional lead screws 9 are threadedly connected to guide sliders 10, causing the guide sliders 10 to move along the direction of the guide grooves 8, bringing the two moving frames 5 closer together. The two conveyor belts 6 can simultaneously convey and bend multiple rebars, thus improving the efficiency of rebar bending.
