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.
[0020] like Figure 1 As shown, the rail heel end forging heat treatment device provided by the utility model comprises a heating mechanism, a forging mechanism and a connecting rail 1, wherein the connecting rail 1 is used to support the heating mechanism;
[0021] The heating mechanism includes a moving frame 2, a vortex tube 3, a mounting ring 4 and an extrusion plate 5. A feeding hole 6 is provided inside the moving frame 2. The vortex tube 3 is arranged inside the feeding hole 6. The vortex tube 3 is used to heat the rail. The mounting ring 4 is fixedly connected to one side of the moving frame 2. The extrusion plate 5 is arranged on the inner surface of the mounting ring 4. The extrusion plate 5 is used to remove oxide scale.
[0022] The forging mechanism includes a fixed frame 7, a support seat 8 and a hydraulic rod 9. The hydraulic rod 9 is fixedly connected to the top of the fixed frame 7 and the output end passes through the fixed frame 7. The support seat 8 is arranged at the bottom of the fixed frame 7. The upper surface of the support seat 8 is detachably connected with a replacement mold 18.
[0023] The movable frame 2 can slide on the connecting rail 1, and the rail is driven to move by the front-end equipment. The rail passes through the movable frame 2 from the feeding hole 6, so that the vortex tube 3 arranged in the feeding pipe heats the rail. The movable frame 2 can move, so as to heat the rail in a larger range and improve the uniformity of the heating process. The heated rail is transported to the bottom of the forging mechanism, and the rail is forged by the forging mechanism. The replacement die 18 can be replaced as needed to adapt to rails of different specifications. The extrusion plate 5 contacts the heated rail to scrape off the oxide scale attached to the rail, thereby reducing the impact on subsequent processes. At the same time, the movable frame 2 can drive the extrusion plate 5 to slide on the surface of the rail to improve the efficiency of removing the oxide scale.
[0024] like Figure 2 As shown, in the present embodiment, a threaded rod 10 is connected through one side of the mounting ring 4, and a connecting plate 11 is provided at one end of the threaded rod 10 located inside the mounting ring 4. The connecting plate 11 is detachably connected to the extrusion plate 5 through a clamping mechanism, and bristles 19 are provided on one side of the extrusion plate 5. The clamping mechanism includes a connecting groove 12 opened on one side of the connecting plate 11 and a connecting block 13 fixedly connected to one side of the extrusion plate 5. The connecting block 13 is slidably connected to the connecting groove 12, and a fixing bolt 14 is provided on one side of the connecting plate 11. The fixing bolt 14 penetrates the connecting plate 11, and the fixing bolt 14 threadably connects the end of the connecting plate 11 penetrated by the connecting bolt to the extrusion plate 5.
[0025] During the rotation of the threaded rod 10, the threaded rod 10 drives the connecting plate 11 at one end to move, so that the extrusion plate 5 can be pressed against the rail and the oxide scale attached to the surface of the rail can be better scraped off. The extrusion plate 5 can be replaced. After the connecting block 13 is inserted into the connecting groove 12, the connecting plate 11 and the extrusion plate 5 can be connected together, and the two can be fixed together with the fixing bolts 14. After the bristles 19 are worn out after a period of use, the extrusion plate 5 can be replaced. The bristles 19 are made of metal and are used to resist the high temperature on the surface of the rail.
[0026] A driving motor 15 is provided on one side of the mobile frame 2 of the present embodiment. The output end of the driving motor 15 is meshed with the connecting rail 1 through a gear. The driving motor 15 is used to drive the mobile frame 2 to slide. The output end of the driving motor 15 is connected to a gear. When the gear rotates, the mobile frame 2 is driven to slide horizontally on the connecting rail 1, thereby cleaning the surface of the rail and making the heating process more uniform.

The hydraulic rod 9 drives the forging plate 16 to move up and down, and forges the rail blank on the replacement die 18 to forge the rail into a required size. The replacement die 18 is arranged in the positioning groove 17, and the positioning groove 17 can fix the replacement die 18, thereby reducing the shaking of the die during the forging process and improving the stability of production.
[0028] When the rail heel end forging heat treatment device of this embodiment is used to perform heel end forging, the working steps are as follows:
[0029] 1. During operation, the steel rails processed by the previous equipment are passed through the feeding hole 6, and the threaded rod 10 is rotated to press the bristles 19 against the outer surface of the steel rails;
[0030] 2. After adjustment, heat the rails and turn on the drive motor 15, which drives the moving frame 2 to move and clean the oxide scale on the outer surface of the rails;
[0031] 3. The heated rails are transported to the forging mechanism, where they are extruded and formed by the hydraulic rod 9.
