[0030] Please see Figures 1-4 This utility model provides a technical solution: a rebar pressing device, including a rebar pressing equipment frame 1, a rebar roller pressing device, the rebar roller pressing device being disposed inside the rebar pressing equipment frame 1, and a rebar conveying device, the rebar conveying device being disposed inside the rebar pressing equipment frame 1. The rebar conveying device includes a first drive motor 4, the first drive motor 4 being fixedly connected to the left side of the rebar pressing equipment frame 1. Two first rotating shafts 5 are rotatably connected to the inner wall of the rebar pressing equipment frame 1. First rebar conveying rollers 6 are fixedly connected to the surfaces of the two first rotating shafts 5. Gears 7 are fixedly connected to the surfaces of the two first rebar conveying rollers 6. The two gears 7 mesh with each other. The output end of the first drive motor 4 is fixedly connected to the corresponding first rotating shaft 5. Two second rotating shafts 8 are rotatably connected inside the rebar pressing equipment frame 1. Second rebar conveying rollers 9 are fixedly connected to the surfaces of the two second rotating shafts 8. A fixed frame 10 is fixedly connected to the inner wall of the rebar pressing equipment frame 1. Two third rebar conveying rollers 11 are rotatably connected inside the fixed frame 10.
[0031] There are two sets of the second rotating shaft 8, the second threaded steel conveying roller 9, the fixed frame 10, and the third threaded steel conveying roller 11, which are distributed in a linear array inside the frame 1 of the threaded steel pressing equipment.
[0032] The rebar rolling device includes a hydraulic rod 15, which is fixedly connected inside the rebar pressing equipment frame 1. The output end of the hydraulic rod 15 is fixedly connected to a roller fixing frame 16. Two slide rods 19 are fixedly connected to the surface of the roller fixing frame 16, and both slide rods 19 are slidably connected to the rebar pressing equipment frame 1. A second drive motor 17 is fixedly connected to the upper end of the roller fixing frame 16, and a rebar pressing roller 18 is fixedly connected to the output end of the second drive motor 17.
[0033] There are two rebar roller pressing devices, which are symmetrically arranged on both sides of the rebar pressing equipment frame 1.
[0034] The front end of the rebar pressing equipment frame 1 is fixedly connected to the rebar input frame 2, and the rear end of the rebar pressing equipment frame 1 is fixedly connected to the rebar output frame 3. Both the rebar input frame 2 and the rebar output frame 3 are funnel-shaped.
[0035] An electromagnetic heater 12 is fixedly installed on the inner wall of the rebar pressing equipment frame 1, and an electromagnetic heating coil 13 is fixedly installed on the electromagnetic heater 12. A rebar guide plate 14 is fixedly connected to the inner wall of the rebar pressing equipment frame 1.
[0036] When using this device, the high-temperature rebar to be processed is first inserted into the rebar pressing equipment frame 1 through the rebar input frame 2, and the rebar comes into contact with the first rebar conveying roller 6. At the same time, the first drive motor 4 is started to drive the first rotating shaft 5 and the first rebar conveying roller 6 to rotate. The first rotating shaft 5 drives the gear 7 to rotate, which in turn drives the other first rotating shaft 5 and the first rebar conveying roller 6 to rotate, facilitating the conveying of the rebar by the two first rebar conveying rollers 6. During the conveying process, the rebar passes through the second rebar conveying roller 9 and the third rebar conveying roller 11, which drive the second rebar conveying roller 9 and the third rebar conveying roller 11 to rotate. The use of the second rebar conveying roller 9 and the third rebar conveying roller 11 facilitates the support and conveying of the rebar, effectively straightens the rebar, maintains its straightness during the conveying process, avoids the deformation of the rebar during the conveying process, straightens bent rebar, corrects the bending and deviation that may occur in the rebar during the pressing process, ensures that the shape and size of the product meet the requirements, and improves the production quality of the rebar.
[0037] As the surface temperature of the rebar may decrease during the conveying process of the second rebar conveying roller 9 and the third rebar conveying roller 11, the electromagnetic heater 12 is activated to energize the electromagnetic heating coil 13, generating eddy currents inside the electromagnetic heating coil 13. This reheats the rebar that has passed through the electromagnetic heating coil 13, facilitating the softening of the rebar. Reheating can make the internal structure of the rebar more stable, reduce possible deformation during use, maintain the geometric dimensions and performance stability of the workpiece, help eliminate residual stress inside the rebar, and improve the performance of the workpiece.
[0038] After heating, the rebar is guided by the rebar guide plate 14 and conveyed between the two rebar pressure rollers 18. The hydraulic rod 15 is activated to drive the pressure roller fixing frame 16 to move. The pressure roller fixing frame 16 drives the slide rod 19 to slide inside the rebar pressing equipment frame 1. The pressure roller fixing frame 16 drives the second drive motor 17 and the rebar pressure rollers 18 to move, so that the two rebar pressure rollers 18 squeeze the rebar. At the same time, the second drive motor 17 is activated to drive the rebar pressure rollers 18 to rotate, which facilitates the pressing and forming of the rebar. The surface of the rebar is extruded to produce thread-like protrusions. Finally, the pressed rebar is discharged from the rebar output frame 3.
[0039] Furthermore, by using the second threaded steel conveying roller 9 and the third threaded steel conveying roller 11, the threaded steel can be effectively straightened, maintaining its straight state during the conveying process. This can correct any bending or deviation that may occur during the pressing process, ensuring that the shape and size of the product meet the requirements, reducing deformation and cracking problems in subsequent processing and use, thereby improving product quality and stability, enhancing the production quality and precision of the threaded steel, and increasing the production efficiency of the device.
[0040] The rebar is reheated by the electromagnetic heater 12 and the electromagnetic heating coil 13. Reheating can make the internal structure of the rebar more stable, reduce the deformation that may occur during use, maintain the geometric dimensions and performance stability of the workpiece, help eliminate residual stress inside the rebar, improve the performance of the workpiece, adjust the mechanical properties of the rebar, and improve the quality of the rebar.
[0041] Working Principle: When using this device, the high-temperature rebar to be processed is first inserted into the rebar pressing equipment frame 1 through the rebar input frame 2, and the rebar comes into contact with the first rebar conveying roller 6. At the same time, the first drive motor 4 is started to drive the first rotating shaft 5 and the first rebar conveying roller 6 to rotate. The first rotating shaft 5 drives the gear 7 to rotate, which in turn drives the other first rotating shaft 5 and the first rebar conveying roller 6 to rotate, facilitating the conveying of the rebar by the two first rebar conveying rollers 6. During the conveying process, the rebar passes through the second rebar conveying roller 9 and the third rebar conveying roller 11, which drive the second rebar conveying roller 9 and the third rebar conveying roller 11 to rotate. The use of the second rebar conveying roller 9 and the third rebar conveying roller 11 facilitates the support and conveying of the rebar, effectively straightening the rebar and maintaining its straightness during the conveying process. This avoids deformation of the rebar during the conveying process, straightens bent rebar, corrects bending and deviations that may occur during the pressing process, ensures that the shape and size of the product meet the requirements, and improves the production quality of the rebar.
[0042] As the surface temperature of the rebar may decrease during the conveying process of the second rebar conveying roller 9 and the third rebar conveying roller 11, the electromagnetic heater 12 is activated to energize the electromagnetic heating coil 13, generating eddy currents inside the electromagnetic heating coil 13. This reheats the rebar that has passed through the electromagnetic heating coil 13, facilitating the softening of the rebar. Reheating can make the internal structure of the rebar more stable, reduce possible deformation during use, maintain the geometric dimensions and performance stability of the workpiece, help eliminate residual stress inside the rebar, and improve the performance of the workpiece.
[0043] After heating, the rebar is guided by the rebar guide plate 14 and conveyed between the two rebar pressure rollers 18. The hydraulic rod 15 is activated to drive the pressure roller fixing frame 16 to move. The pressure roller fixing frame 16 drives the slide rod 19 to slide inside the rebar pressing equipment frame 1. The pressure roller fixing frame 16 drives the second drive motor 17 and the rebar pressure rollers 18 to move, so that the two rebar pressure rollers 18 squeeze the rebar. At the same time, the second drive motor 17 is activated to drive the rebar pressure rollers 18 to rotate, which facilitates the pressing and forming of the rebar. The surface of the rebar is extruded to produce thread-like protrusions. Finally, the pressed rebar is discharged from the rebar output frame 3.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
