Abrasion interval compensation device for floating uncoiling machine

Abstract

The invention relates to an abrasion interval compensation device for a floating uncoiling machine, comprising a base, wherein the base is welded on a device base, an inclined chute is fixed on the base, a working surface at the bottom of the inclined chute is a smooth inclined surface, the shoulder of the inclined chute is used for limiting a regulating wedge in the inclined chute, an inclined surface of the regulating wedge is adhered with an inclined surface of the inclined chute and is an inclined surface with equal gradient, a short oblong hole and a screw hole are machined in an L-shaped lug of the regulating wedge, a lubricating slot is arranged on a friction working surface of the regulating wedge, a positioning screw is screwed down on the base after penetrating through the nut and the short oblong hole of the regulating wedge, a fastening screw is screwed down with the regulating wedge through a thread, and a cylindrical end of the fastening screw is tightly jacked on the end surface of the base, a pre-tightening screw passes through corresponding oblong holes of the base and the inclined chute so that the threaded end is screwed into the screw hole of the regulating wedge, thus the inclined surfaces of the inclined chute and the regulating wedge are ensured to be mutually adhered. According to the total compensation amount of abrasion intervals, the gradients and the lengths of the inclined surfaces of the inclined chute and the regulating wedge are determined; the lengths of various screws and oblong holes are determined according to the travel of the regulating wedge; in addition, the structure is simple and compact and is convenient to be regulated.

Description

technical field [0001] The invention relates to a floating uncoiler in strip rolling, in particular to a wear gap compensation device for the floating uncoiler. Background technique [0002] During the strip rolling production process, the main body of the floating uncoiler slides in the guide rail of the base through the automatic centering device to perform real-time centering to ensure that the center of the strip is always kept at the center of the unit to prevent the strip from deviation. Due to the long-lasting sliding friction between the uncoiler body and the guide rail, there will be a wear gap, which will affect the real-time centering effect and is not conducive to the precision of the rolled product. When the wear is serious, it is usually necessary to replace the guide rail or the alloy slide plate on the uncoiler body, resulting in certain economic losses. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior a...
