The one-way adjustable cutting structure 6 includes a hydraulic rod 61 fixedly installed on the bottom end of the inner wall of the frame 1, a movable seat 62 is clamped and installed on the top of the hydraulic rod 61, a guide rod 63 is symmetrically welded on the top of the movable seat 62, and a movable seat 64 is sleeved on the outside of the two guide rods 63, a disc 65 is fixedly installed on one end of the movable seat 64, a first one-way shaft 66 is installed inside the disc 65 through an interference fit, a cylinder 67 is installed inside the first one-way shaft 66 through an interference fit, a second one-way bearing 68 is installed on the outside of the cylinder 67 through an interference fit, a gear 69 is installed on the outside of the second one-way bearing 68 through an interference fit, a rack 610 is meshed and connected on the outside of the gear 69 and the rack 610 is fixedly installed at the top edge of the movable seat 62, a rotating seat 611 rotatably connected to the outside of the disc 65 is fixedly installed on the other end of the cylinder 67, and four cutting knives 613 are arranged in a circular array with the center point on the outside of the rotating seat 611.

[0030] like Figure 3 and Figure 4As shown, a limiting groove is opened inside the rotating seat 611, and a limiting ring is welded on the outside of the disc 65. The limiting ring is rotatably connected to the inside of the limiting groove. The rotating seat 611 and the disc 65 are connected via the limiting groove and the limiting ring, which is used for the rotation of the rotating seat 611, changes the rotation difficulty of the rotating seat 611, and prevents the rotating seat 611 and the disc 65 from separating.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the rotation directions of the first one-way shaft 66 and the second one-way bearing 68 are opposite, and the first one-way shaft 66 and the second one-way bearing 68 are connected by a cylinder 67, which can be used to drive the rotating seat 611 to rotate in one direction to prevent the rotating seat 611 from rotating in both directions.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, four support rods 612 are welded equidistantly on the outside of the rotating seat 611 , and one end of the cutting blade 613 is fixedly connected to one end of the support rod 612 , which is used for installing the cutting blade 613 and facilitating the disassembly of the cutting blade 613 .

[0033] like Figure 3 and Figure 4 As shown, a connecting strip 614 is symmetrically welded to the bottom end of the disc 65, and a V-shaped plate 615 is fixedly installed to the bottom end of the inner wall of the connecting strip 614. A rounded corner is provided on the bottom edge of the V-shaped plate 615 to reduce the strength of the bottom end so that one end face of the V-shaped plate 615 can be flipped. A guide strip 616 is symmetrically welded to the edge of one end of the V-shaped plate 615 away from the hydraulic rod 61, and grinding discs 617 are symmetrically embedded and installed on both end faces of the V-shaped plate 615, which can facilitate the grinding of the rotating cutting knife 613, prevent residues from accumulating on the surface of the cutting knife 613 during the steel bar cutting process, and ensure the cleanliness of the surface of the cutting knife 613.

[0034] like Figure 3 and Figure 6 As shown, a clamping strip 618 is symmetrically welded to the bottom end of the movable seat 64, and a fixing structure 7 is fixedly installed on the outer side of the clamping strip 618;

[0035] The fixed structure 7 includes a triangular block 71 which is attached to the outer side of the clamping strip 618, and a movable plate 72 is fixedly installed on one end face of the triangular block 71 away from the clamping strip 618, and a spring rod 73 is symmetrically embedded and installed on one end face of the movable plate 72, and a rectangular plate 74 is symmetrically clamped and installed on one end face of the spring rod 73, and a screw rod 75 is rotatably connected to one end of the rectangular plate 74, and a limiting seat 76 is movably connected to the outer side of the screw rod 75. The bottom end of the movable seat 64 and the top end of the limiting seat 76 are attached to each other, which are used to limit the shortest distance between the movable seat 64 and the ground, thereby changing the difficulty of limiting it. One end of the limiting seat 76 is fixedly installed on one end of the frame 1, which can facilitate the fixation of the limiting seat 76 and fix the movable seat 64, thereby changing the difficulty of fixing the movable seat 64.

[0036] like Figure 3 and Figure 6 As shown, a connecting column 77 is welded between the two screw rods 75. The thread directions of the two screw rods 75 are opposite, which can facilitate the relative movement of the two rectangular plates 74 and change the relative movement difficulty of the two rectangular plates 74.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, a limiting frame 8 is fixedly installed on the outer side of the fixed end of the hydraulic rod 61, and the bottom end of the limiting frame 8 is fixedly installed on the bottom end of the inner wall of the frame 1, which can facilitate the installation of the hydraulic rod 61 and change the difficulty of installing and fixing the hydraulic rod 61.

[0038] like Figure 1 and Figure 2 As shown, the discharge pipe 9 and the feed roller 2 are connected by a chain transmission structure, and guide rollers are fixedly installed in the middle of the outer surface of the discharge pipe 9 and the feed roller 2, which is convenient for guiding the steel bars and allows the two discharge pipes 9 and the feed roller 2 to rotate synchronously, thereby changing the difficulty of their synchronous rotation.

[0039] Working principle: During the actual use of the device, the rolled steel bar enters the feed cover 3 along the feed roller 2, and presses the feed cover 3 to enter the heating tube 4. At this time, the heating wire 5 is connected to the power supply and starts to operate. As the heating wire 5 is operating, the heating tube 4 is heated and turns red. At this time, the heating tube 4 generates temperature and heats the steel bar. The heated steel bar enters the collection device along the discharge pipe 9. At this time, the hydraulic rod 61 is started. When the hydraulic rod 61 rises, it drives the moving seat 62 to move. When the moving seat 62 moves, it drives the guide rod 63 to move inside the movable seat 64. In the process, the moving seat 62 drives the rack 610 to move. When the rack 610 moves, it drives the gear 69 to rotate. When the gear 69 rotates, it rotates along the locking direction through the first one-way shaft 66, so that when the first one-way shaft 66 rotates in the locking direction, the first one-way shaft 66 rotates. The outer ring and the inner ring of the first one-way shaft 66 rotate synchronously. When the outer ring and the inner ring of the first one-way shaft 66 rotate synchronously, the cylinder 67 rotates. When the cylinder 67 rotates, it drives the second one-way bearing 68 to rotate in a direction that cannot be locked, so that the outer ring and the inner ring of the second one-way bearing 68 can rotate separately. When the cylinder 67 rotates, it drives the rotating seat 611 to rotate synchronously. When the rotating seat 611 rotates, it drives the cutting knife 613 to rotate through the support rod 612. By switching multiple cutting knives 613, it is prevented that a single cutting knife 613 is always cutting the hot-rolled steel bars, so that the use intensity of a single cutting knife 613 can be reduced, thereby extending its service life. This can not only reduce long-term maintenance costs, but also reduce the number of times the cutting knife 613 is replaced, improve overall production efficiency, and prevent the cutting knife 613 from producing natural phenomena, thereby increasing its safety factor.

[0040] Then, the hydraulic rod 61 is started, and the hydraulic rod 61 abuts against the movable seat 64 through the movable seat 62, and pushes the movable seat 64 to move. When the movable seat 64 moves, it drives the clamping strip 618 to move, and the clamping strip 618 moves along the outer side of the triangular block 71. When the triangular block 71 moves, it drives the movable plate 72 to move, and when the movable plate 72 moves, it drives the spring rod 73 to be compressed, so that the movable seat 64 and the limit seat 76 can be fixed to prevent the rack 610 from causing the movable seat 64 to move when the gear 69 is driven to rotate, thereby increasing the stability of the cutting blade 613 during the switching process, further facilitating the switching of the cutting blade 613, and rotating the screw rod 75. The two screw rods 75 rotate synchronously through the connecting column 77, so that the two triangular blocks 71 are close to each other, thereby increasing the extrusion force between the clamping strip 618 and the fixed structure 7, and further increasing the stability of the cutting blade 613 during the switching process;

[0041] When the hydraulic rod 61 continues to move, the hydraulic rod 61 rises and drives the rotating cutter 613 to cut the hot-rolled steel bar under the action of the support rod 612, and then resets. Since the inner and outer rings of the first one-way shaft 66 can rotate during the reset, when the movable seat 62 and the movable seat 64 are separated, the rack 610 drives the gear 69 to rotate. When the gear 69 rotates, the outer ring of the first one-way shaft 66 rotates along the inner ring. Since the cutter 613 and the support rod 612 contact the guide bar 616 when they rotate, the cutter 613 and the support rod 612 abut against the guide bar 616, so that The guide bar 616 is deflected, and when the guide bar 616 deflects, it drives the outer side of the V-shaped plate 615 to deflect. When the outer side of the V-shaped plate 615 deflects, it drives the grinding disc 617 to contact the outer side of the used cutting knife 613, thereby grinding the cutting knife 613 and removing the residue on the outer side of the cutting knife 613 due to the cutting of hot-rolled steel bars, ensuring the cleanliness of the surface of the cutting knife 613, thereby ensuring that the cutting knife 613 maintains a precise shape and cutting edge, maintains cutting accuracy, and helps to reduce the risk of wear and breakage of the cutting knife 613, thereby extending the service life of the cutting knife 613 and reducing maintenance and replacement costs.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
