Centering and guiding device for steel strip processing

Abstract

The invention discloses a centering and guiding device for steel strip processing and belongs to the field of steel rolling equipment. The centering and guiding device comprises a base, an adjusting mechanism, a guiding mechanism and a centering mechanism, wherein the guiding mechanism comprises an upper horizontal roller and a lower horizontal roller, and two ends of the upper horizontal roller and two ends of the lower horizontal roller are fixed on supports on two sides of the base separately; the adjusting mechanism comprises a control hand wheel, an adjusting screw rod, nuts, flat keys and nut sleeves, two sections of threads are formed on the adjusting screw rod, each section of threads is matched with the corresponding nut, and the nut sleeves are arranged on the outer side surfaces of the nuts and fixedly connected with the flat keys on the nuts; the centering mechanism comprises sliding blocks and vertical rollers, the sliding blocks are fixedly connected above the nut sleeves, the vertical rollers are symmetrically arranged at two ends of each sliding block, and the vertical rollers are distributed on two sides of one end of the upper horizontal roller. According to the centering and guiding device for the steel strip processing, the position can be adjusted automatically according to the width of a steel strip, the vertical rollers are clamped on two sides of the steel strip all along, so that leftward and rightward offset of the steel strip is avoided, and the problems that the steel strip gets stuck, is flanged and is warped are also solved.

Description

technical field

[0001] The invention relates to the technical field of steel rolling equipment, and more specifically, relates to a centering and guiding device applied in a steel strip pickling line. Background technique

[0002] In the prior art, during subsequent processing of hot-rolled steel coils, in order to remove the oxide scale attached to the surface of the steel strip, the steel strip must first be pickled. Generally, the guide roller is used to introduce the steel strip into the pickling tank. The length of the washing tank is long. When the steel strip is slightly offset from the side, the collision between the steel strip and the pickling tank is easy to occur. To avoid this phenomenon, it is often necessary to set a centering guide device in the pickling line to make the steel strip Keep your position stable while traveling.

[0003] At present, most enterprises use the vertical roller guide device to maintain the stability of the steel belt in the process o...
