[0002] Hot-rolled coil, as an important industrial raw material, is made from slabs through a series of complex processing steps. First, the slabs must be heated in a high-temperature environment to reach a suitable processing temperature, and then enter the roughing mill. In the roughing mill, the slabs undergo initial rolling deformation, and their shape and size begin to change significantly. Then, the semi-finished products after rough rolling will be transported to the finishing mill, where more refined rolling is carried out to obtain the required key indicators, and finally form hot-rolled coils.

[0003] However, during the entire coil processing process, collisions and frictions will occur between the coils, and irregular edge materials will inevitably be produced.

The transmission assembly can ensure that the cutting action is performed while the rotating plate 210 is parallel to the collection box 201, and the rotating plate 210 can now act as a cutting plate;

[0035] Specifically, when the waste is collected to a certain extent, the servo motor 203 drives the rotating shaft 204 to rotate, thereby driving the rotating plate 210 to rotate to a parallel position. At the same time, the bevel gear transmission assembly bevel gear 1 205 and bevel gear 2 206 drive the cutting tool 2 211 to move upward to cut the waste, which can cut large pieces of waste into smaller sizes, facilitating the subsequent transportation, storage and reuse of the waste. The dynamic assembly adopts the meshing transmission of bevel gear 1 205 and bevel gear 2 206 to convert the horizontal rotation of the rotating shaft 204 into the vertical rotation of the threaded rod 207. This transmission structure It is compact and has high transmission efficiency. It can accurately realize the up and down movement of the cutting tool 211. The threaded connection between the slider 1 208 and the threaded rod 207 and the sliding connection between the slider 213 and the support rod 214 provide stable guidance and support for the movement of the cutting tool 211, ensuring the linear motion accuracy of the tool and avoiding shaking or offset of the tool, thereby ensuring the consistency and reliability of the cutting effect. At the same time, when the rotating plate 210 is parallel to the collection box 201, the rotating plate 210 can act as a cutting plate. The model of the servo motor 203 is CMP50M.

[0036] Reference Figure 1, the left and right sides of the top of the support seat 1 are fixedly connected with fixed plates 19 to provide support, and the adjacent sides of the two fixed plates 19 are fixedly connected with connecting columns 20; the bottoms of the two connecting columns 20 are fixedly connected with abutment plates 21, and the bottoms of the two abutment plates 21 are both set on the top of the raw material 13. The abutment plates 21 keep the raw material 13 in a relatively stable state through close contact with the raw material 13;

[0037] Specifically, the connecting column 20 connects the support plate 21 with the fixed plate 19, providing a stable support structure for the support plate 21. The support plate 21 presses on the top of the raw material 13, which can effectively prevent the raw material 13 from jumping up and down or shifting during cutting.

[0038] Working principle: The hot-rolled coil raw material 13 to be cut is placed in the die press 3 and conveyed toward the support seat 1. The raw material 13 can slide forward on the support seat 1 through the rotation of the conveying roller 14 for subsequent cutting operations. The servo motor 1 is started, and the output end of the servo motor 1 drives the transmission wheel 1 6 to rotate. The transmission wheel 1 6 drives the transmission wheel 2 7 to rotate through the belt 8. Since the transmission wheel 2 7 is fixedly connected to the bidirectional threaded rod 9, the transmission wheel 2 7 drives the bidirectional threaded rod 9 to rotate on the inner side of the gantry 4. When the bidirectional threaded rod 9 rotates, the fixed blocks 10 threadedly connected to the left and right sides of its outer wall will move relative to or opposite to each other according to the direction of the thread. When the fixed block 10 moves, it drives the connecting seat 11 and the cutting tool 12 to move together, thereby adjusting the distance between the two cutting tools 12 to meet the cutting requirements of hot-rolled coils of different widths.

[0039] And when the cutting tool 12 cuts the hot-rolled coil raw material 13, the generated waste will fall down and fall into the collection box 201 below along the inclined rotating plate 210. When the waste is collected to a certain extent, the servo motor 203 is started, and the output end of the servo motor 203 drives the rotating shaft 204 to rotate. The two ends of the rotating shaft 204 are supported and rotatably connected by the shaft seat 209. When the rotating plate 210 fixed on the outer wall of the rotating shaft 204 rotates with the rotating shaft 204 to a position parallel to the collection box 201, it engages with the bevel gear 2 206 through the bevel gear 1 205, driving the threaded rod 2 207 to rotate. At this time, the slider 1 208 moves upward along the threaded rod 207, driving the cutting tool 2 211 to move upward to cut the waste in the collection box 201.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
