[0028] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] The present application provides a steel bar straightening protection device, such as Figure 1-Figure 4 As shown, the steel bar straightening protection device includes a protection cover 1 and a bearing 2; the protection cover 1 is used to be detachably connected to the entrance of the steel bar straightening machine and to accommodate the coiled steel bar coil; the bearing 2 is arranged in the protection cover 1 and is located on the side of the protection cover 1 close to the steel bar straightening machine; the bearing 2 is used for the steel bar to pass through.

[0030] In the present application, the protective cover 1 is used to contain the coil of coiled steel bars, thereby limiting the coil of coiled steel bars and forming a confinement zone when the steel bars are straightened; at the same time, the bearing 2 guides and limits the steel bars, so that the free end of the coil of coiled steel bars passes through the bearing 2 and enters the steel bar straightening machine. Under the dual limiting effect of the protective cover 1 and the bearing 2 on the steel bars, the twisting of the steel bars in the process of entering the steel bar straightening machine is controlled and limited to swing within the range of the protective cover 1, which enhances the mechanical safety of the steel bar straightening, protects the safety of the processing personnel, and avoids unintentional injuries due to excessive swinging of the steel bars during the straightening process.

[0031] In one embodiment of the present application, Figure 1 , Figure 3 and Figure 4 As shown, the protective cover 1 includes a first cover body 11 and a second cover body 12; the first cover body 11 is detachably connected to the inlet of the steel bar straightening machine, and the second cover body 12 is connected to an end of the first cover body 11 away from the steel bar straightening machine.

[0032] The first cover body 11 is a cylindrical cover body, the bearing 2 is located in the first cover body 11 and is coaxially arranged with the first cover body 11; the second cover body 12 is a truncated cone-shaped cover body, and the small diameter end of the second cover body 12 is connected to the first cover body 11.

[0033] In this embodiment, due to the truncated cone structure of the second cover body 12, the receiving space of the second cover body 12 gradually changes along the axial direction of the second cover body 12, so the second cover body 12 can adapt to coils of different sizes of coiled steel bars, and has stronger adaptability. The cylindrical structure of the first cover body 11 makes the internal space of the first cover body 11 more regular than that of the second cover body 12, making it easier to install and position the bearing 2.

[0034] At the same time, the bearing 2 is placed closer to the steel bar straightening machine relative to the second cover body 12, so as to guide and limit the transmission of the steel bars into the steel bar straightening machine; compared with setting the bearing 2 in the second cover body 12, setting the bearing 2 in the first cover body 11 can reduce the force during the steel bar straightening process and play a certain buffering role.

[0035] Furthermore, the cylindrical structure of the first cover body 11 can make it easier for the first cover body 11 to be installed in coordination with the steel bar straightening machine, thereby improving the stability of the assembly between the protective cover 1 and the steel bar straightening machine.

[0036] In one embodiment of the present application, the first cover body 11 and the second cover body 12 are an integrally formed structure, thereby ensuring the stability of the connection between the first cover body 11 and the second cover body 12, and ensuring that the second cover body 12 is not easily separated from the first cover body 11 even under the swinging force of the steel bars during the steel bar straightening process.

[0037] In one embodiment of the present application, along the axial direction of the protective cover 1, the height of the first cover body 11 is less than 1 / 2 of the height of the second cover body 12, so that when the second cover body 12 accommodates and limits the coiled steel bar coil, the overall structure of the protective cover 1 can offset the torque generated during the steel bar processing and straightening process, further reducing the unsafety caused by the swinging of the steel bar.

[0038] In one embodiment of the present application, the diameter of the first cover 11 is less than 1 / 2 of the maximum radius of the second cover 12, thereby further limiting the swing range of the steel bar when inserted into the steel bar straightening machine. The radius of the bearing 2 is 1 / 4 to 1 / 2 times the radius of the first cover 11, which not only ensures the limiting and guiding effect of the bearing 2 on the steel bar and reduces the swing of the steel bar, but also facilitates the maintenance of the bearing 2 in the first cover 11.

[0039] In one embodiment of the present application, Figure 1 As shown, the steel bar straightening protection device further includes two connection units 3, both of which are distributed around the bearing 2 and are respectively connected to the bearing 2 and the protection cover 1; the two connection units 3 are arranged in a cross shape. The connection unit 3 includes two connection rods 31, as shown in FIG. Figure 1-Figure 4 As shown, two connecting rods 31 are distributed on both sides of the bearing 2 along the radial direction of the bearing 2; the connecting rods 31 are connected to the bearing 2 and the protective cover 1 respectively.

[0040] Four connecting rods 31 are arranged along the circumferential direction of the bearing 2 and are distributed in a cross shape, thereby connecting the bearing 2 to the first cover 11 and making the force distribution of the bearing 2 uniform, ensuring that the bearing 2 can be more stable when the steel bar passes through, thereby extending the service life of the bearing 2.

[0041] like Figure 1 and Figure 4 As shown, the protective cover 1 is provided with a mounting hole 4, and a part of the connecting rod 31 is located in the mounting hole 4; the connecting rod 31 is a square connecting rod 31, and the mounting hole 4 is a square mounting hole 4. Specifically, the mounting hole 4 is provided on the first cover body 11, so as to install and position the connecting rod 31. The mounting hole 4 can increase the contact area between the connecting rod 31 and the first cover body 11, thereby improving the stability of the bearing 2 installed in the first cover body 11. In addition, the mounting hole 4 and the connecting rod 31 both adopt a square structure, which can prevent the connecting rod 31 from rotating in the mounting hole 4, and further improve the stability of the bearing 2 installed in the first cover body 11.

[0042] In one embodiment of the present application, Figure 1-Figure 4 As shown, the steel bar straightening protection device also includes a mounting portion 5, which is circumferentially arranged outside the protection cover 1; a plurality of threaded holes 51 are arranged on the mounting portion 5 along the circumferential direction, and the threaded holes 51 are detachably connected to the steel bar straightening machine through threaded connectors.

[0043] The mounting portion 5 is used to detachably connect the protective cover 1 to the steel bar straightening machine, so as to avoid the reduction of the strength of the protective cover 1 caused by arranging the threaded hole 51 on the protective cover 1. Specifically, the mounting portion 5 is arranged at one end of the first cover body 11 away from the second cover body 12; the mounting portion 5 is annular, and the inner diameter of the mounting portion 5 is larger than the inner diameter of the first cover body 11, so that an annular groove is formed between the first cover body 11 and the mounting portion 5, such as Figure 2 and Figure 4 As shown, the groove is connected to the first cover body 11. An elastic pad is arranged in the groove to reduce the friction generated after the protective cover 1 is assembled with the steel bar straightening machine, further extending the service life of the steel bar straightening protective device.

[0044] In summary, the utility model provides a steel bar straightening protection device, which includes: a protective cover, which is used to be detachably connected to the entrance of the steel bar straightening machine and accommodate the coiled steel bar coil; a bearing, which is arranged in the protective cover and is located on the side of the protective cover close to the steel bar straightening machine; the bearing is used for the steel bar to pass through. In this application, the coiled steel bar coil is accommodated by the protective cover, so as to limit the coiled steel bar coil and form a confinement area during steel bar straightening; at the same time, the bearing guides and limits the steel bar, so that the free end of the coiled steel bar coil enters the steel bar straightening machine after passing through the bearing. Under the dual limiting effect of the protective cover and the bearing on the steel bar, the torsion of the steel bar in the process of entering the steel bar straightening machine is controlled, and it is limited to swing within the range of the protective cover, which enhances the mechanical safety of steel bar straightening, protects the safety of processing personnel, and avoids unintentional injury to people due to excessive swinging of the steel bar during the straightening process.
