Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling production equipment, in particular to a guide groove device used in conjunction with a rolling mill. Background Art

[0002] In modern steel rolling production, the mill's six-bar production line plays a crucial role. It primarily produces rebar bars through two-slit, three-slit, and single-line processes to meet the demands of various construction and engineering sectors. This line features an efficient and complex design, consisting of three mill units: roughing, intermediate, and finishing. Mill 18 in the finishing unit serves as the finished product stand, directly impacting the quality of the final product.

[0003] During the finishing rolling stage, especially after the 18# rolling mill, two sections of guide grooves (ducts) are set up to accurately guide the rolled pieces into the controlled cooling device to ensure the cooling effect and final performance of the steel. However, this design encountered some challenges in actual operation, especially when replacing the 18# rolling mill. When replacing the 18# rolling mill, due to the mill being hoisted out and the first section of the guide groove behind the stand (the specific structure of the first section of the guide groove is as follows Figures 1-4 Because of physical interference (as shown), this section of the guide trough must be removed before the mill can be lifted out and replaced. This process is not only cumbersome and time-consuming, but it directly impacts the overall efficiency and output of the production line. The installation of the guide trough relies on tightening screws, but the inner side of the guide trough is occupied by other equipment, making the removal and reinstallation of the tightening screws on the inner side of the guide trough mounting base extremely difficult. This not only prolongs the time required to replace the mill but also increases the workload of operators. Furthermore, if the guide trough's tightening screws are not fully tightened due to interference, the guide trough may shift during rolling, leading to rolling failures. This not only affects product quality and production indicators, but also poses a safety hazard to operators and increases additional troubleshooting costs. In view of these issues, there is an urgent need to design a rolling mill guide trough device that can be quickly installed or removed. Summary of the Invention

DETAILED DESCRIPTION

[0025] The utility model is further described in detail below with reference to the accompanying drawings:

[0026] like Figure 1-5The guide groove device of a rolling mill shown in the figure can be quickly installed or removed, which includes a guide groove body 2-1 and a guide groove mounting base 2-2, and the guide groove body 2-1 is installed on the guide groove mounting base 2-2 through the guide groove bottom plate 2-3 located at the bottom thereof; on the inner side of the guide groove, the guide groove bottom plate 2-3 is provided with a guide groove bottom plate slot hole 2-4 with a side opening, that is, the hole for placing the inner screw 1-4 of the guide groove bottom plate 1-3 in the background technology is changed into a guide groove bottom plate slot hole 2-4 with a side opening; the guide groove mounting base 2-2 is also provided with a guide groove mounting base slot hole 2-5 that matches it at the position corresponding to the guide groove bottom plate slot hole 2-3, and a pin mounting rod 2-6 is provided in the guide groove bottom plate slot hole 2-4 and the guide groove mounting base slot hole 2-5, wherein the guide groove bottom plate slot hole 2-4 and the guide groove mounting base slot hole 2-5 together constitute the basis for installing the pin mounting rod 2-6. A pin hole 2-7 is provided on the upper part of the pin mounting rod 2-6, and a plug 2-8 is installed in the pin hole 2-7; the lower part of the pin mounting rod 2-6 is installed on the bottom of the guide groove mounting base 2-2 through a bearing 2-9 and a connecting block 2-10. After the plug 2-8 is pulled out, the pin mounting rod 2-6 can rotate along the guide groove bottom plate slot hole 2-4 and the guide groove mounting base slot hole 2-5 toward the inside of the guide groove. With such arrangement, when replacing the rolling mill, to remove the guide groove, one only needs to knock out the pin 2-8 located on the upper part of the pin mounting rod 2-6 on the inner side of the guide groove, slightly loosen the nut of the fastening screw 2-11 on the outer side, and then the guide groove can be rotated outward on the guide groove mounting base 2-2; after replacing the rolling mill, the guide groove can be quickly moved to the rolling line position, tighten the pin 2-8 located on the upper part of the pin mounting rod 2-6 on the inner side of the guide groove, and tighten the nut on the outer side. This simplifies the operating procedures of the operators, reduces the labor intensity of the employees, and has good social benefits.

[0027] On the outside of the guide groove, the guide groove bottom plate 2-3 and the guide groove mounting base 2-2 are connected and fixed by fastening screws 2-11. Such a design makes the installation process easier and also improves the overall strength of the structure.

[0028] The upper portion of the pin mounting rod 2-6 is a cylindrical structure, which is convenient for processing and manufacturing and is conducive to close cooperation with the latch 2-8.

[0029] The latch 2-8 is a rectangular parallelepiped latch, which is not only easy to insert and remove, but also effectively prevents the latch 2-8 from loosening in the pin hole 2-7.

[0030] The workflow of replacing the rolling mill using the utility model is as follows:

[0031] When replacing the rolling mill, it is only necessary to knock out the pin 2-8 located on the upper part of the pin mounting rod 2-6 on the inner side of the guide groove, slightly loosen the nut of the outer fastening screw 2-11, and then the guide groove can be rotated outward on the guide groove mounting base 2-2; after replacing the rolling mill, the guide groove can be quickly moved to the rolling line position, tighten the pin 2-8 located on the upper part of the pin mounting rod 2-6 on the inner side of the guide groove, and tighten the nut on the outer side.

[0032] Compared with the first section guide groove device behind the existing frame in the background technology, the utility model mainly changes the structure of the fixed part of the guide groove installation of the rolling mill, so that the time for each replacement of the rolling mill is shortened by about 3 minutes compared with before, and the output can be increased by about 7 tons.

[0033] Furthermore, the utility model does not loosen or deviate during the rolling process to cause rolling failure, thereby reducing rolling failures and improving production indicators.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
