Abstract
The invention relates to a package element for protecting steel roll angle region, which includes a ring-type angle protection element with orthogonal or near orthogonal vertical section, and a overlap part bent inward along inner edge equipped at ring-shape face opposite to the ring-type angle protection element and steel roll end face. The package element includes outer angle protecting element and inner angle protecting element, can saves one third steel compared to package element using same thickness steel plate and has same mechanism capability, moreover, edge of the package element is smooth and is convenient for installing and operating.
Description
Technical field:
The present invention relates to a kind of packaging element that is used to cover, protect steel folding corner region, especially relating to a kind of is the packaging element that L shaped annular arrangement corner protector constitutes by section.
Background technology:
Existing coil of strip is a hollow cylinder, and volume is big because coil of strip has, quality heavily reaches characteristics such as sharp edges, so, in storage or transportation, need carry out protective package to coil of strip.The known package element comprises the cylinder backplate of protecting the coil of strip outer cylinder by sheet steel or plasticity composite panel being used to of constituting and is arranged on two end faces of coil of strip and the end face backplate identical with its shape, and with identical or akin inside and outside these the three kinds of elements of Corner protecting board of the folding corner region shape of two end faces of coil of strip.In these three kinds of packaging elements, cylinder backplate and end face backplate just play package action to coil of strip, to prevent coil of strip by the erosion of wet gas and water, can prevent also that simultaneously the coil of strip surface from being scratched by the rigidity object or wound; And interior exterior angle backplate is except that steel folding corner region is had the defencive function; also need to bear its powerful application force that applies of strapping; particularly when handling; the coil of strip overall weight acts on the interior exterior angle backplate by steel rope; under the effect of this application force, very easily cause the packaging element of steel rope two side areas to produce corrugated projection; even make the force part fracture, so should having predetermined rigidity, the particularly inside and outside corner protector of above-mentioned packaging element could guarantee its packing effect.
Outer corner protector of the prior art all is to adopt and identical or akin cylindricality ring of the external diameter shape of coil of strip and the L shaped structure that interior annulus constituted that radially bends inwards and extend along an end of this cylindricality ring, and inner protective corner spare has one with the hollow identical or akin interior cylindrical ring of internal diameter shape of coil of strip with along an outer toroid that the end extends radially outwardly of this interior cylindrical ring.Want to improve the rigidity of this inside and outside corner protector, unique solutions is the thickness that increases inside and outside corner protector, and the increase meeting of its thickness directly improves cost of manufacture, and this packaging element is disposable and the very large parts of consumption, its thickness integrates the cost that can increase up to ten million units as increasing by 1 millimeter.
For the outer corner protector that packed steel coil is used, the position that can be subjected to application force that steel rope applies is interior annulus, and the cylindricality ring mainly is to play the effect that limits interior annulus position; For inner protective corner spare, the position that can be subjected to the application force that steel rope applies is an outer toroid, and the main effect of interior cylindrical ring also is to play the effect that limits the outer toroid position, so, the quality of outer corner protector depends on interior annulus, and the quality of inner protective corner spare depends on outer toroid.
Summary of the invention:
The purpose of this invention is to provide a kind of packaging element that utilizes the mode that changes structure to solve the protection coil of strip end regions of packing cost problem.
The packaging element of protection coil of strip end regions proposed by the invention comprises that profile is right angle or the annular arrangement corner protector that approaches square, and the ring surface that described annular arrangement corner protector is relative with the coil of strip end face is provided with from the inside edge to the overlapping portion of back bending folding.The annular arrangement corner protector comprises outer corner protector and/or inner protective corner spare, outer corner protector or inner protective corner spare all have and the contacted ring surface of coil of strip end face, and ring surface is the force part of packaging element, what overlapping portion was set thereon can increase its load-carrying capacity, and position-limiting action is just played at other position of circular corner protector, when the handling coil of strip, also can not apply how many application forces to these positions, so, even if the very thin quality that also can not influence packaging element in other position except that ring surface.
Described annular arrangement corner protector comprises outer corner protector, the internal spherical surface that should outer corner protector has the formation that radially bends inwards with the shape of coil of strip external diameter and the identical or akin exterior cylindrical ring of size with along an end of this exterior cylindrical ring, internal spherical surface is provided with from the inside edge the first overlapping portion to the back bending folding, at internal spherical surface together with the convex-concave portion that radially is provided with of the first overlapping portion or be provided with the rib rib that at least one circle protrudes from this plane, annulus place.
The exterior cylindrical ring of described outer corner protector is being provided with annular ridge near the position of internal spherical surface, rolls over the formed second overlapping portion and be provided with from outer edge at the end regions of its other end to back bending.
Described annular arrangement corner protector comprises inner protective corner spare, this inner protective corner spare has an interior cylindrical ring identical or close with size with the shape of the hollow internal diameter of coil of strip and along an outer annular surface that the end extends radially outwardly of this interior cylindrical ring, the outer annular surface setting is from the three overlapping portion of outer edge to the back bending folding.The described the 3rd overlapping covers whole outer annular surface or extends to an interior cylindrical ring part.
The packaging element of protection coil of strip end regions proposed by the invention comprises outer corner protector and/or inner protective corner spare, if packaging element adopts the thick steel plate of 0.5mm to make, the internal spherical surface of outer corner protector and the outer annular surface of inner protective corner spare are equivalent to the thick plate of 1mm, compare with the packaging element of directly making with the thick steel plate of 1mm and will save 1/3rd steel at least, but both mechanical characteristicss are identical, by statistics, the annual 700000 tons of steel plates of consumption that need of this type of packaging element of the whole nation, if can save 1/3rd packing, its value will be above 10,000,000,000 yuan; Simultaneously, because of the outer annular surface of the internal spherical surface of outer corner protector and inner protective corner spare is to adopt same block of plate and form by the mode to the back bending folding, do not have a burr so its edge is smooth, not needle-holding hand when mounted brings convenience to fitting operation; In addition, the convex-concave portion that is provided with on the outer corner protector internal spherical surface is equivalent to increase many rib ribs thereon, not only can increase the rigidity of outer corner protector, and the recess of its formation is suitable for limiting the position of strapping, and then can prevent effectively that strapping from coming off.
