Description

Technical Field

[0001] The utility model belongs to the technical field of guide and guard installation and adjustment, and more specifically relates to a guide and guard adjustment device used for guide and guard installation. Background Art

[0002] With the development of modern steel technology, in order to achieve high yield, high quality and low consumption of bars, modern small bar rolling workshops have generally adopted advanced short stress rolling mills. Due to its high rigidity, high product precision, light equipment weight, simple operation and good working reliability, it occupies a dominant position in the world's small rolling mill models. The bar cutting process mainly includes three processes: shearing, tearing and deformation. The shearing stage is to shear the box-type hole through the K4 pre-cutting pass, and the cutting hole of the K4 pass continues to be reprocessed along the pre-cutting hole of K3; the tearing stage is to use the cutting guide to tear the hole open to form a one-point multi-form; the deformation stage is to roll and regularize the material through the K2 and K1 passes, and finally form a rebar that meets the process requirements.

[0003] In the process of bar cutting, steel deformation is an important link. Steel deformation is mainly affected by the yield criterion and stress-strain relationship. The yield criterion describes the conditions under which the material begins to enter plastic deformation, while the stress-strain relationship describes the deformation law of the material after being subjected to force. Based on these relationships, the deformation behavior of steel during the cutting process can be better controlled to improve product quality.

[0004] The bar cutting guide system is the key to ensure the smooth cutting process. The factors that need to be considered in the design of the guide system include the guide form, material and heat treatment process. The guide forms mainly include sliding, rolling and floating types. When choosing a suitable guide form, factors such as the diameter, length, surface quality of the bar, and friction and deformation during the cutting process need to be considered. The selection of guide materials depends on the use environment and the wear resistance, fatigue resistance and strength of the material. The heat treatment process also has a great influence on the service life and performance of the guide, which needs to be determined according to the type of material and the use requirements of the guide.

[0005] In the actual production process, guide installation is an important operation process for the finishing rolling adjuster. The traditional adjustment method is that the adjuster uses the material bar rolled out in the previous pass as a sample bar, and adjusts the guide centering at the guide installation position of the actual production line, and then waits for the shutdown or shift change period to install the online guide. The sample bar and the naked eye are often used to judge whether the guide installation is aligned with the rolling groove. This method has many disadvantages. It is difficult to install the guide in one go and achieve precise centering due to factors such as space, field of view, and perspective. It is very easy to produce trial rolling scraps. It often takes 2-3 steel bars to adjust the guide installation position properly. Basically, every shift change will produce trial rolling scraps. Utility Model Content
