Problems solved by technology

[0002] After the existing slitting unit passes through the slitting device, it is directly sent to the winder through the guide roller for winding operation. At this time, the tension of the steel strip after slitting is insufficient, and the steel strip is easily wound in the winder. In-plane curling and superimposition will result in a decline in the quality of formed steel coils, resulting in re-leveling and slitting, resulting in low production efficiency

Abstract

The invention provides a pre-distributing tension damping device. By using the pre-distributing tension damping device, the tension is enough when steel strips enter a take-up machine, the take-up quality of the steel strips in the take-up machine is ensured, and the production efficiency is improved. The pre-distributing tension damping device comprises a base; and a board structure is arranged above the base. The pre-distributing tension damping device is characterized in that a guiding roll structure is arranged in front of the board structure; the guiding roll structure is fastened in front of the upper portion of the base; two positioning rolls which are arranged transversely are arranged at the rear of the board structure; a pushing roll is arranged between the two positioning rolls; a rotating shaft of the pushing roll is supported to two side walls of a base of the pushing roll; the side walls of the base of the pushing roll have outwards convex structures; outwards convex structures of side walls of the positioning rolls are clamped in perpendicular guiding grooves of the board structure; and a rear hydraulic cylinder is arranged on the rear side of the upper end of the board structure.

Description

technical field [0001] The invention relates to the technical field of winding structures of hot-rolled steel coils, in particular to a pre-dividing tension damping device. Background technique [0002] After the existing slitting unit passes through the slitting device, it is directly sent to the winder through the guide roller for winding operation. At this time, the tension of the steel strip after slitting is insufficient, and the steel strip is easily wound in the winder. When in-plane curling and superimposition occur, the quality of formed steel coils decreases, resulting in re-leveling and slitting, resulting in low production efficiency. Contents of the invention [0003] In view of the above problems, the present invention provides a pre-dividing tension damping device, which ensures sufficient tension before the steel strip enters the winder, ensures the winding quality of the steel coil in the winder, and improves production efficiency. [0004] A pre-divi...
