Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment in the rolling process of the steel industry, specifically to a spliced ​​outlet guide. Background Technology

[0002] In the steel industry, the rolling process is a crucial step in production. To ensure that the steel billet is rolled according to predetermined deformation conditions, inlet and outlet guides are used to precisely guide the billet. For example... Figure 1 As shown, traditional export guide designs typically employ a two-piece, interlocking structure. This design creates a narrow gap in the middle, which easily leads to problems such as chipping and steel sticking. When the billet passes through such a guide, the gap causes scratches to appear on the bottom of the billet, severely affecting product quality. These quality issues not only increase the workload of subsequent rectification and rework but also reduce production efficiency. Utility Model Content

[0005] Furthermore, the lower L-shaped guide plate includes a first horizontal portion and a first vertical portion;

[0006] The upper L-shaped guide plate includes a second horizontal part and a second vertical part;

[0007] The upper part of the first horizontal part away from the first vertical part is provided with a first stepped groove, the shape of which matches the lower end of the second vertical part, so that the lower end of the second vertical part can be embedded in the first stepped groove.

[0008] The lower part of the second horizontal section away from the second vertical section is provided with a second stepped groove. The shape of the second stepped groove matches the upper end of the first vertical section, so that the upper end of the first vertical section can be embedded in the second stepped groove.

[0009] Furthermore, guide grooves are provided above and below the installation port of the outlet guide box, and guide protrusions adapted to the guide grooves are provided at the lower part of the first horizontal part and the upper part of the second horizontal part.

[0010] Furthermore, locking screws are provided on both sides and the top of the outlet guide box. These locking screws are used to firmly attach the upper L-shaped guide plate and the lower L-shaped guide plate together.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] See attached document Figure 2 -Appendix Figure 4 The technical solution provided by this utility model is a spliced ​​outlet guide, including an outlet guide box 1 and a guide assembly. The outlet guide box 1 is provided with an installation port through which the guide assembly passes. The guide assembly includes a lower L-shaped guide plate 2 and an upper L-shaped guide plate 3. The upper L-shaped guide plate 3 is placed on the lower L-shaped guide plate 2, and a material guide port 4 is formed between the upper L-shaped guide plate 3 and the lower L-shaped guide plate 2.

[0025] First, to fundamentally solve the problem of steel sticking caused by narrow gaps, this embodiment features an innovative design for the guide assembly. Specifically, the lower L-shaped guide plate 2 is composed of a first horizontal portion 21 and a first vertical portion 22, while the upper L-shaped guide plate 3 is composed of a second horizontal portion 31 and a second vertical portion 32. This design cleverly utilizes the L-shaped structure, allowing the narrow gaps to be transferred to the sides when the two are assembled, greatly reducing the risk of steel peeling and sticking.

[0026] Furthermore, to achieve a tighter fit, a first stepped groove 23 is designed on the upper part of the first horizontal section 21 away from the first vertical section 22. Its shape perfectly matches the lower end of the second vertical section 32, ensuring that the lower end of the second vertical section 32 can be securely embedded in the first stepped groove 23. Similarly, a second stepped groove 33 is also provided on the lower part of the second horizontal section 31 away from the second vertical section 32, matching the upper end of the first vertical section 22. This achieves a double fit between the upper and lower L-shaped guide plates in both the horizontal and vertical directions, enhancing the stability and sealing of the structure.

[0027] To ensure precise alignment of the L-shaped guide plate during installation, this embodiment provides guide grooves 5 above and below the mounting opening of the outlet guide box 1. Correspondingly, the lower part of the first horizontal section 21 and the upper part of the second horizontal section 31 are equipped with guide protrusions 6 that mate with the guide grooves 5. This design not only simplifies the installation process but also ensures the accuracy of the guide assembly's position after installation, further reducing quality problems caused by installation errors.

[0028] To ensure a secure fit between the L-shaped guide plates, this embodiment includes locking screws 7 on both sides and the top of the outlet guide box 1. By tightening these locking screws 7, the upper L-shaped guide plate 3 and the lower L-shaped guide plate 2 can be firmly joined together, preventing loosening due to vibration or impact during rolling and further improving the durability and stability of the guides.

[0029] To reduce friction and heat accumulation during the rolling process, this embodiment features a threaded hole on the second horizontal section 31, with a cold water nozzle 8 threadedly connected to it. By spraying cooling water into the guide area, not only can the temperature be effectively reduced, but the generation of yellow fumes can also be eliminated, improving the working environment.

[0030] To optimize the billet feeding process, this embodiment also features a specially designed tongue tip 9, which is formed by combining the feeding ends of the upper L-shaped guide plate 3 and the lower L-shaped guide plate 2. This design can guide the billet into the rolls more smoothly, reducing jamming and scratching problems caused by poor feeding.

[0031] Finally, to enhance the stability and support capacity of the entire exit guide structure, this embodiment features a dovetail support base 10 with a keyway at the lower end of the exit guide box 1. This design not only provides a stable support surface but also facilitates precise alignment and fixation with connecting components of the rolling mill or other equipment via the keyway, ensuring the reliability and durability of the entire guide system. Working principle: The exit guide is modified into two "L"-shaped pieces, with the seam moved to the side. This design reduces the likelihood of warping or steel adhesion, effectively preventing marking issues.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
