Along the X-axis, a sawing mechanism 3, a stripping and threading mechanism 4, and a grinding mechanism 6 are sequentially mounted on the frame 1. Rebar clamps 2 are respectively mounted on the top of the frame 1 corresponding to the sawing mechanism 3, the stripping and threading mechanism 4, and the grinding mechanism 6. A sawing moving mechanism 7, which drives the sawing mechanism 3 to move along the X-axis, a threading moving mechanism 8, which drives the stripping and threading mechanism 4 to move along the Y-axis, and a grinding moving mechanism 9, which drives the grinding mechanism 6 to move along the X-axis, are mounted on the frame 1. The sawing mechanism 3 has a sawing base plate 31, and a saw blade 33 and a sawing motor 32, which drives the saw blade 33 to rotate, are mounted on the top of the sawing base plate 31. The sawing moving mechanism 7… The sawing base plate 31 is driven to move along the X-axis direction. In this embodiment, the axis of the reinforcing bar is arranged along the Y-axis direction, driving the reinforcing bar to move laterally along the X-axis direction, and move sequentially to the sawing mechanism 3, the rib stripping and threading mechanism 4, and the grinding mechanism 6 for sawing, rib stripping and threading, and grinding, respectively. It can cooperate with the external reinforcing bar transverse conveying equipment to achieve automated continuous processing and improve processing efficiency. The sawing mechanism 3, the rib stripping and threading mechanism 4, and the grinding mechanism 6 are integrated on the same frame 1 along a straight line and can be processed continuously, avoiding the material turnover area between scattered equipment and reducing the processing area. The reinforcing bar clamps 2 corresponding to the sawing mechanism 3, the rib stripping and threading mechanism 4, and the grinding mechanism 6 can clamp and fix the reinforcing bar during sawing, rib stripping and threading, and grinding to prevent the reinforcing bar from moving during processing.
[0028] In the above embodiment, the sawing motor 32 in the sawing mechanism 3 drives the saw blade 33 to rotate at high speed, and the sawing moving mechanism 7 drives the sawing base plate 31 to move the high-speed rotating saw blade 33 along the X-axis direction to realize the sawing processing of the end of the steel bar.

[0037] In some embodiments, both the sawing mechanism 3 and the grinding mechanism 6 are provided with an alignment component 5; the alignment component 5 has an alignment push plate 52 and a push plate cylinder 51 that drives the alignment push plate 52 to reciprocate along the Y-axis direction; when the reinforcing bar moves to the sawing mechanism 3 and the grinding mechanism 6, the push plate cylinder 51 drives the alignment push plate 52 to move, the alignment push plate 52 contacts the end of the reinforcing bar and pushes it to position. After positioning is completed, the corresponding reinforcing bar clamp 2 clamps and fixes the reinforcing bar, and then sawing and grinding can begin.
