Abstract

The invention discloses a steel coil uncoiling production line, and belongs to the technical field of unfolding equipment. The steel coil uncoiling production line comprises a pay-off device rotationally installed on a supporting frame. A traction roller pair is arranged on the downstream side of the pay-off device. A transition roller is arranged between the traction roller pair and the pay-off device. The pay-off device comprises a transmission shaft rotationally installed on the supporting frame. A plurality of distraction roller sheets are arranged on the periphery of the transmission shaft in an annular array mode. Each distraction roller sheet is arc-shaped. A first distraction air cylinder and a second distraction air cylinder are arranged between each distraction roller sheet and the transmission shaft. Cylinder bodies of the first distraction air cylinders and the second distraction air cylinders are installed on the transmission shaft in a hinged mode. A distraction gap exists between every two adjacent distraction roller sheets. The steel coil uncoiling production line is good in uncoiling effect, the residual internal stress of a steel strap can be further effectively eliminated after uncoiling, and the steel coil uncoiling production line is compact in structure, is good in use performance and has good application potential and popularization value.

Description

technical field [0001] The invention relates to an uncoiling production line, more particularly to a steel coil uncoiling production line, which belongs to the technical field of flattening equipment. Background technique [0002] Among the current technologies, steel coils are a common production raw material, such as automobile shells in the field of automobile manufacturing, various thin steel pipes, and can be directly processed into various steel plates and steel strips. When using steel coils for further processing, the coils first need to be uncoiled to form flat steel plates and cut to size. An uncoiler is required during the uncoiling process. [0003] However, there is no support in the middle of the steel coil at present, which may easily cause the inner diameter of the steel coil to be out of round. When the steel coil is installed on the roll of the uncoiler, the inner diameter of the steel coil does not match the size of the roll of the uncoiler, causing probl...
