[0002] Steel is a material formed into a specific shape, size, and properties through pressure processing, such as ingots, billets, or other materials. Most steel processing involves pressure working, which causes plastic deformation of the steel (billets, ingots, etc.). Depending on the temperature at which steel is processed, it can be categorized as cold working or hot working.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The utility model provides Figure 1 and Figure 2 The steel heat treatment equipment shown includes a transmission platform 1. The front side of the transmission platform 1 is fixedly connected to a support rod 11. The upper end of the support rod 11 is fixedly connected to a fixed bracket 12. The inner side of the fixed bracket 12 is rotatably connected to multiple sets of conveyor rollers 13. The rear side of the fixed bracket 12 is fixedly connected to a drive mechanism 14. A limiting mechanism is provided between the fixed bracket 12 and the transmission platform 1. The limiting mechanism includes a support frame 2, a transmission gear 22, a transmission rod 24, a transmission rack 26, a connecting plate 210, a rotating rod 211, and an electric cylinder 212. The support frame 2 is fixedly connected to the upper surface of the transmission platform 1. There are multiple rotating rods 211, each located between adjacent conveyor rollers 13. The rear end of the transmission platform 1 is fixedly connected to a heat treatment box 3.

[0033] Among them, the driving mechanism 14 is a prior art and will not be described in detail here; the round steel is placed above the conveying roller 13. At this time, the driving mechanism 14 drives multiple groups of conveying rollers 13 to rotate to convey the round steel. During the conveying of the round steel, the telescopic rod in the electric cylinder 212 pulls the front transmission rod 24 to the right, and the transmission gear 22 and the transmission rack 26 cooperate to drive the two groups of transmission rods 24 to slide toward each other. The transmission rod 24 drives the rotating rods 211 on both sides to move closer to the inside, limiting the round steel and preventing the round steel from shaking left and right during the conveying process.

[0034] See Figure 3 and Figure 4 The middle part of the support frame 2 is fixedly connected with a support cross bar 21, and the transmission gear 22 is rotatably connected to the middle part of the support cross bar 21. There are two groups of transmission rods 24, and the two groups of transmission rods 24 are respectively located on the front and rear sides of the transmission gear 22. The surface of the transmission rod 24 close to the transmission gear 22 is fixedly connected with the transmission rack 26, and the transmission rack 26 is meshed with the transmission gear 22. The front and rear ends of the support cross bar 21 are fixedly connected with a positioning block 23, and a positioning groove 25 is provided on the surface of the transmission rod 24. The positioning groove 25 is slidably connected to the positioning block 23. 2 are fixedly connected to the limit collar 27 on both sides, and the end of the transmission rod 24 away from the transmission gear 22 is fixedly connected to the limit rod 28, and the limit rod 28 is slidably connected to the limit collar 27. The right side of the support frame 2 is fixedly installed with an electric cylinder 212, and the telescopic rod of the electric cylinder 212 is fixedly connected to the right end of the front transmission rod 24. The end of the upper surface of the transmission rod 24 away from the transmission gear 22 is fixedly connected with a connecting block 29, and the upper end of the connecting block 29 is fixedly connected to the connecting plate 210. The upper surface of the connecting plate 210 is rotatably connected to multiple groups of rotating rods 211.

[0035] Specifically, during the adjustment process, the limiting mechanism pulls the front transmission rod 24 to the right through the telescopic rod of the electric cylinder 212, and the front transmission rod 24 drives the transmission gear 22 to rotate through the transmission rack 26. The transmission gear 22 drives the rear transmission rod 24 to slide to the left through the rear transmission rack 26, thereby driving the two sets of connecting plates 210 to move closer to the inside at the same time, and then driving multiple sets of rotating rods 211 to move closer to the inside to clamp and position the round steel; at the same time, during the sliding process of the transmission rod 24, the positioning block 23 slides inside the positioning groove 25, and the limiting rod 28 slides inside the limiting collar 27, which limits the position of the transmission rod 24 and improves the stability of the transmission rod 24 during use.

[0036] See Figure 5 A feed port 31 is provided at the front end of the heat treatment box 3, and a plug-in slot is provided on the upper surface of the heat treatment box 3 near the front end. A sealing plate 34 is slidably connected to the inside of the plug-in slot. A gantry 32 is fixedly connected to the front side of the heat treatment box 3, and a hydraulic cylinder 33 is fixedly installed on the upper end of the gantry 32. The telescopic rod in the hydraulic cylinder 33 is fixedly connected to the upper end of the sealing plate 34.

[0037] At the same time, when the round steel is transported to the heat treatment box 3, the telescopic rod in the hydraulic cylinder 33 pulls the sealing plate 34 upward to open the feed port 31, thereby preventing the feed port 31 from being open for a long time and maintaining the temperature inside the heat treatment box 3.

[0038] The working principle of the present invention is as follows: in order to improve the stability of round steel during the transportation process, the front transmission rod 24 is pulled to the right by the telescopic rod in the electric cylinder 212, and the transmission gear 22 and the transmission rack 26 cooperate to drive the two groups of transmission rods 24 to slide in opposite directions, and the transmission rod 24 drives the rotating rods 211 on both sides to move closer to the inside, limiting the position of the round steel, avoiding the left and right shaking of the round steel during the transportation process, and thus improving the stability of the round steel during the transportation process.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
