Abstract

The utility model relates to an uncoiling perching knife of a hot rolling box and is a component arranged on the uncoiling arm of the hot rolling box. The utility model comprises a swing frame which is provided with a compression roller and a jointing roller, and is characterized in that a separated waste head is arranged on the swing frame, and an uncoiling roller is arranged at the separated waste head parts. The outer diameter of the uncoiling roller is 140 mm, the outer diameter of the compression roller is 353 mm and the outer diameter of the jointing roller is 203 mm. The utility model is arranged on the uncoiling arm of the hot rolling box. When uncoiling, the jointing roller joints the outer circle of the steel coil, and the uncoiling roller rolls downward along the outer circle of the steel coil to reach the uncoiling aim. The utility model is tested in the hot tandem rolling factory of the tisco stainless steel stock limited company in Shanxi for six months. The uncoiling effect is good without the phenomenon that steel coil surface is scuffed or splicing matter is brought into the steel coil.

Description

A kind of Coil Box uncoiling perching knife

Technical field:

The utility model is the parts that are installed on the Coil Box uncoiling arm.

Background technology:

Existing uncoiling perching knife in operating process since the uncoiling perching knife along the coil of strip outer ring to lower slider, the phenomenon that perching knife scratches the coil of strip surface often takes place, cause the coil of strip quality to reduce, cause the certain economic loss to enterprise.

Summary of the invention:

The utility model aims to provide a kind of a kind of Coil Box uncoiling perching knife that does not scratch the coil of strip surface.

The realization the technical solution of the utility model is: comprise swing frame, pressure roller is installed on the swing frame, is pressed close to roller, it is characterized in that swing frame is provided with the branch crop, the branch crop place of swing frame is equipped with pay-off roll, the external diameter of this pay-off roll is 140 millimeters, and the external diameter of pressure roller is 353 millimeters, and the external diameter of pressing close to roller is 203 millimeters.

The utility model is installed on the Coil Box uncoiling arm, and after pressing close to roller during uncoiling and pressing close to the coil of strip outer ring, pay-off roll is rolled downwards along the coil of strip outer ring, reaches the purpose of uncoiling.The utility model was hot continuous rolling factory of Shanxi Taigang Stainless Steel Co., Ltd test six months, uncoiling is respond well, the phenomenon on coil of strip surface does not take place to scratch, do not occur sticky object yet and bring the interior phenomenon of coil of strip into, improved product quality, saved maintenance time, improved production efficiency, the phenomenon that the quality of having avoided invar volume surface tear to cause reduces.
