When the guide mechanism 3 stops conveying the steel bar, the bending mechanism 5 can start to bend the steel bar. After the steel bar is bent, the cutting mechanism 4 starts to cut off the formed lifting ear. After cutting, the lifting ear is removed, and the guide mechanism 3 continues to guide the steel bar forward, thereby realizing continuous production of the lifting ear.
[0021] like Figure 2As shown, as a preferred embodiment of the present invention, the guide mechanism 3 includes: a guide tube 31, which is fixedly mounted on the platform 1, and the steel bar can pass through the guide tube 31; a wheel rod 32, which is fixedly mounted in the guide tube 31 and is provided with a plurality of wheels, a first wheel frame 33 is fixedly provided on the wheel rod 32, and a guide wheel 34 is rotatably provided in the first wheel frame 33; a large pulley 35, which is coaxially connected to the guide wheel 34, and the large pulley 35 is coaxially connected to the small pulley 36, and a belt 3 is connected between adjacent large pulleys 35 and small pulleys 36. 7; a driving assembly 38, which is mounted on a first wheel frame 33 and coaxially connected to the guide wheel 34, and is used to drive the guide wheel 34 to rotate stably on the first wheel frame 33; a sleeve 39, which is fixedly mounted on the side of the guide tube 31 away from the wheel rod 32, and a sleeve rod 310 is slidably provided on the sleeve 39, and a second wheel frame 311 is fixedly provided on the sleeve rod 310, and a pressure wheel 312 is rotatably mounted on the second wheel frame 311, and a compression spring 313 is fixedly connected between the second wheel frame 311 and the sleeve 39 for pushing the pressure wheel 312 to close to the steel bar.
