Description

Technical Field

[0001] The utility model relates to the field of flat steel rolling mills, and more specifically, to a novel side rolling mill for flat steel deformation. Background Art

[0002] In the flat steel production line, it is necessary to level the flat steel bars after longitudinal shearing and stripping, and the product quality control requirement is that the straightness of the strips after leveling is 1mm / m.

[0003] However, due to problems with the production process of carbon steel hot coils, the edge material thickness and metal microstructure are unstable, resulting in poor straightness after slitting and a large number of defective products. It is necessary to cooperate with the side rolling mill for leveling operations. However, in the existing side rolling mill structure, there is a lack of adjustable and limiting support rollers and swing support plates on both sides, resulting in poor stability in the feeding and discharging of flat steel, which is prone to interference and needs to be improved.

[0026] A counterweight rod 24 is fixedly connected to the lower surface of the swing shaft 22, and a limit block 25 is threadedly installed on the bottom of the counterweight rod 24. A counterweight ring 26 is sleeved on one end of the counterweight rod 24, and the counterweight ring 26 is stacked on one side of the limit block 25. The support roller 21 and the swing support plate 23 are distributed on one side of the bracket 2 at intervals. The limit block and the counterweight ring are connected by the counterweight rod, and can be installed and positioned in combination for easy adjustment and use. The flat steel is supported by the support roller 21 to facilitate its transportation to the space between the upper roller 13 and the lower roller 12 for rolling. At this time, the swing support plate 23 is tightened by the counterweight ring 26 at the bottom to maintain a horizontal position to avoid interference. When the end of the flat steel contacts one side of the swing support plate 23, it causes an imbalance on both sides and flips around the swing shaft 22 to move at an angle, so that one side can be higher than the surface of the support roller 21, which can limit the entry of subsequent flat steel, thereby avoiding mutual interference and facilitating adjustment and use.
