Embodiment Construction

[0021] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] A steel coil core anti-loosening buckle, refer to Figure 1-2 , including a clamping body 1, the clamping body 1 is a strip-shaped steel plate, the clamping body 1 can be made of steel such as spring steel or EXT800, and the clamping body 1 is made of spring steel here.

[0023] The middle part of the clamping body 1 is bent in a "U" shape along the direction perpendicular to its length to form a bent part 11 . When it is necessary to roll up the steel coil with a loose core, insert and clamp multiple buckles on the 2-3 layers inside the steel coil. Here, two buckles are used to clamp and fix the coil core of the steel coil, one of which is clamped and fixed at a distance of 50 cm from the end of the steel coil coil core, and the other is clamped and fixed on the opposite side of the buckle, reducing the The end of th...

Abstract

The invention provides an anti-loose buckle for a roll core of a steel roll, and relates to the technical field of inner coil clamping tools. The anti-loose buckle comprises a clamping body which is a long-strip-shaped steel plate, wherein the clamping body is bent in a U shape in the direction perpendicular to the length direction of the clamping body to form a bent part, and a deformation joint facilitating deformation of the clamping body is formed in the middle of the clamping body. The anti-loose buckle has the advantage of conveniently clamping the steel coil with the loose coil core so as to reduce the influence of the reduction of the inner diameter of the coil core on the subsequent processing of the steel coil.

Description

technical field [0001] The invention relates to the technical field of inward coil clamping tools, in particular to an anti-loose buckle for steel coil cores. Background technique [0002] The raw material of the continuous hot-dip galvanizing / continuous annealing production line is cold-rolled steel coil. With the development of steel technology, the thickness specification of cold-rolled steel strip is getting thinner and thinner, and the thinnest can reach 0.1mm. Thin-gauge products will cause the coil core to loosen during unloading, hoisting, and transportation. If the final inner diameter is smaller than the minimum shrinkage diameter of the uncoiler mandrel at the entrance of the hot-dip galvanizing / continuous annealing unit, it will loosen during the coiling process. As a result, the mandrel of the uncoiler is in contact with the winding core, and a core pulling problem occurs. In serious cases, the material needs to be returned, and even the unit is stopped, which a...
