[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] refer to Figure 1-Figure 3As shown, the present application discloses a finishing rolling device for post-processing of threaded steel bars, in which support legs 6 are installed at the four corners of the lower surface of the support plate 5 to provide support under the support plate 5, and the heating mechanism 1 is installed on the upper surface of the support plate 5, wherein the heating mechanism 1 is provided with a fixed outer tube, a spiral heating tube and a fixed inner tube to achieve heat treatment of the threaded steel bars, and the specific heating process is the prior art, and the specification part of the patent document CN217997256U can be referred to, and will not be described in detail in this application document;

[0020] The support plate 5 is fixedly connected to fixed plates 2 on both sides of the upper surface, and a convex plate 11 is installed at one end of the outer side of the two fixed plates 2. A guide rod 13 is commonly connected between the outer sides of the two convex plates 11. A plurality of limit plates 12 are equidistantly penetrated on the outer side of the guide rod 13 to ensure the stability of multiple limit plates 12 when moving horizontally. A serpentine adjusting rod 4 is commonly rotatably connected to the middle position of the upper surface of the plurality of limit plates 12. An end plate 15 is fixedly connected to a corner of one side of the fixed plate 2, and the end plate 15 rotates with one end of the serpentine adjusting rod 4. The fixed plate 2 on the same side as the end plate 15 is provided with a telescopic mechanism for pushing the limit plate 12 to move. The telescopic mechanism pushes the limit plate 12 fixed thereto to move, causing the serpentine adjusting rod 4 to shrink as a whole, and simultaneously reducing the spacing value of the limit plates 12 between the two, so as to achieve rapid limiting of multiple threaded steel bars.

[0021] refer to Figure 1-Figure 3 As shown, the telescopic mechanism in the device includes an L-shaped plate 7 and a cylinder 14. The L-shaped plate 7 is fixed at the corner of the fixed plate 2 on one side. The cylinder 14 is installed at one end of the L-shaped plate 7, and the telescopic end of the cylinder 14 is fixed to the last limit plate 12. The telescopic end of the cylinder 14 pushes a limit plate 12 fixed thereto to move outside the guide rod 13. Then, when the limit plate 12 moves, the serpentine adjustment rod 4 is deformed as a whole, leading to the same change in the spacing value between the fixed plates 2, so as to adapt to threaded steel bars of different specifications.

[0022] refer to Figure 1-Figure 3 As shown, in the device, a plurality of rotating rollers 10 are rotatably connected between the outsides of the two fixed plates 2, and a plurality of I-shaped guide wheels 3 are equidistantly fixed on the outsides of the plurality of rotating rollers 10. The plurality of I-shaped guide wheels 3 are equidistantly fixed on the outsides of the rotating rollers 10, so that the plurality of threaded steel bars can be conveniently conveyed and guided, and the heating mechanism 1 can be more accurately penetrated through the holes in the heating mechanism 1 to facilitate heating.

[0023] refer to Figure 1-Figure 3 As shown, in the device, a plurality of rectangular strips 16 are distributed circumferentially on the outer ring recesses of a plurality of I-shaped guide wheels 3. The plurality of rectangular strips 16 can increase the friction force of the outer ring recesses, thereby facilitating the movement of the threaded steel bars.

[0024] refer to Figure 1-Figure 3 As shown, in the device, motors 8 are installed at both ends of the outside of a fixed plate 2 on one side, and the output ends of the two motors 8 are respectively fixed to one end of the first and last rotating rollers 10. By starting the motors 8 on both sides, the first and last rotating rollers 10 can be driven to rotate, thereby facilitating the transportation of multiple threaded steel bars.

[0025] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0026] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] The implementation principle of a finishing rolling device for post-processing of threaded steel in an embodiment of the present application is as follows: when in use, a staff member sequentially inserts a plurality of threaded steel bars into a heating mechanism 1, and then starts the cylinder 14 in the telescopic mechanism. Then, the telescopic end of the cylinder 14 pushes a limit plate 12 fixed thereto to move outside a guide rod 13. Then, when the limit plate 12 moves, the serpentine adjustment rod 4 contracts as a whole, driving the remaining limit plates 12 to move synchronously, thereby synchronously reducing the spacing value between the two fixed plates 2, so that the two limit plates 12 of a single threaded steel bar can fit tightly on its outside, thereby achieving simultaneous limiting of a plurality of threaded steel bars, and facilitating the stability of the threaded steel bars during heat treatment inside the heating mechanism 1.
