Description

Technical Field

[0001] The utility model relates to the technical field of roll boxes of multi-roll straightening machines, and specifically relates to a roll box for a multi-roll straightening machine with a high-load-bearing structure. Background Technique

[0002] Multi-roll straightening machines are divided into types such as 5-roll, 9-roll, 11-roll, 13-roll, 17-roll, 19-roll, 21-roll, 23-roll, 25-roll, etc. Different numbers of roll straightening machines are selected according to the thickness and material of the strip. For example, a 5-roll straightening machine is generally used as a straightening head machine, 9-roll and 11-roll straightening machines are generally used for straightening hot-rolled thick steel plates, 11-roll and 13-roll straightening machines are generally used for straightening hot-rolled thin plates, 17-roll, 19-roll and 21-roll straightening machines are mostly used for straightening thick aluminum plates and titanium plates, and 23-roll straightening machines are mostly used for straightening thin aluminum plates, titanium plates and stainless steel plates.

[0003] For example, the patent document with the publication number CN 219378496 U discloses a roll box for a multi-roll straightening machine with high load-bearing performance, including a roll box main body. A number of roll shaft mounting holes are provided on the roll box main body. It also includes a roll bearing frame, and the roll bearing frame is fixedly embedded in the vertical plate of the roll box main body directly below the roll shaft mounting hole through a U-shaped frame. In the roll box of the device of this application, a roll bearing frame is provided. Using the principle of triangular stability, the roll bearing frame is arranged directly below the roll shaft mounting hole to directly bear the weight of the roll shaft, so as to improve the load-bearing capacity of the roll box, reduce the material standard during the production of the roll box, rationally configure the quality of the roll box, and facilitate the installation of the roll box.

[0004] However, in the actual process of this structure, it is often only possible to fixedly install the roll box of the multi-roll straightening machine to ensure the high load-bearing effect of all roll boxes. However, subsequent multi-roll straightening machines cannot perform rapid disassembly and maintenance operations on the roll box alone. At the same time, due to the limitations of the roll box's own structure, the pressure roller cannot be stably damped and limited in the box. During subsequent use, the load-bearing capacity of the roll box cannot be effectively enhanced, and it cannot meet the daily use requirements. Therefore, it is urgent to design a roll box for a multi-roll straightening machine with a high-load-bearing structure to solve the above problems. Content of the Utility Model
