Abstract
The utility model relates to an external bead ring used for packaging steel coil, which is characterized in that the lower side of the radial ring of the external bead ring is bent backward to form a first overlapping part. The utility model has the advantages that due to the overlapping part on the radial ring, the bearing capacity is increased and the cost is reduced; meanwhile; as the same plate is adopted and is bent backward to form the radial ring of the external bead ring, the edge of the radial ring is smooth and has no burr, thereby the installation is convenient due to not stinging hands.
Description
Technical field:
The utility model relates to the outer angle protecting ring that a kind of packed steel coil is used, and relates in particular to a kind of outer angle protecting ring that is made of axial annulus portion and circular radial ring portion.
Background technology:
Outer angle protecting ring is the member that is used for the packed steel coil exterior angle.Outer angle protecting ring of the prior art have the axial annulus portion identical or close with size with the outer cylinder shape of coil of strip and perpendicular to this axial annulus portion and with the circular radial ring portion of an one edge secure bond, and all adopt by a plate through being bent into.Yet because coil of strip is all relative big parts with volume of a kind of quality, and its edge is sharper, so outer angle protecting ring adopts the steel plate with enough rigidity to make usually; Simultaneously, because of outer angle protecting ring is again the parts that bear the strapping application force when tying up coil of strip, particularly when the handling coil of strip, strapping will apply sizable application force to outer angle protecting ring, so, the plate that requires to make outer angle protecting ring has adequate thickness, causes the strapping two side areas to produce corrugated projection or local fracture to avoid outer angle protecting ring under the external force effect of strapping.
From the packing cost aspect, want to improve the quality of above-mentioned outer angle protecting ring, the measure of taking can only be the thickness that increases the plate of making outer angle protecting ring, and the increase of thickness can improve its cost undoubtedly, and outer angle protecting ring 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 this reason, Chinese patent has proposed the technology that a kind of name is called " packaging steel coils plastics outer angle protecting ring " for No. 2488853.Claim that from its disclosed content this corner protector circle includes annulus and forms the casing of one with this annulus, and annulus is provided with a plurality of recesses.Its meaning is to want the plastic production outer angle protecting ring that utilizes cost low, with cost-cutting; Simultaneously, because of the elasticity deficiency of plastics own, so utilize recess to solve or eliminate because of the excessive corner protector circle annulus distortion that causes of the overtension, the sinuousness that are produced that is not complementary of the size between corner protector circle and roll bending.Because plastics matter is crisp, the rigidity deficiency even if its cost is lower, but with regard to the outer angle protecting ring that is used for packed steel coil, adopts plastic production to be difficult to be satisfied with requirements for quality; And the setting of recess not only can not increase the rigidity of corner protector circle, and its rigidity is reduced; Simultaneously, this corner protector circle does not provide the position that limits strapping yet, brings certain difficulty to tying up coil of strip.
Summary of the invention:
The purpose of this utility model provides a kind of outer angle protecting ring that is used for packed steel coil that utilizes the mode that changes self structure to solve the packing cost problem.
The outer angle protecting ring that is used for packed steel coil that the utility model proposed comprise the axial annulus portion identical or close with size with the outer cylinder shape of coil of strip and perpendicular to this axial annulus portion and with the circular radial ring portion of an one edge secure bond, the lower edge of described circular radial ring portion is provided with to back bending rolls over the formed first overlapping portion.
Described first overlapping from the lower edge of circular radial ring portion to the back bending folding and extend to the inside face of axial annulus portion, the circular radial ring portion is 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.
Described axial annulus portion is provided with the annular arrangement fin at the position near folding line, and forms the second overlapping portion at the edge of its other end to the back bending folding.
The circular radial ring portion of the outer angle protecting ring that is used for packed steel coil that the utility model proposed is the force part, be provided with overlapping thereon and can increase its load-carrying capacity, but and cost-cutting, if packaging element adopts the thick steel plate of 0.5mm to make, circular radial ring portion in the outer angle protecting ring is equivalent to the thick plate of 1mm, compare with the outer angle protecting ring of directly making with the thick steel plate of 1mm and will save nearly 1/3rd steel, but both mechanical characteristicss are identical; In addition, because of the circular radial ring portion of outer angle protecting ring 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.

The specific embodiment:
Referring to Fig. 1, this figure provides the overall appearance structure of the embodiment of the outer angle protecting ring that is used for packed steel coil that the utility model proposes.Outer angle protecting ring 1 is the parts that are used for exterior angle, packed steel coil two ends, be to form by the mode of a plate by bending, its profile is right angle or the shape that approaches square, wherein, the face at a square edge place is the identical or akin axial annulus of the external diameter shape with a coil of strip portion 11, and the face at another square edge place is and the corresponding circular radial ring portion 12 of coil of strip end face.When packed steel coil, axial annulus portion 11 is fastened on the outside face of coil of strip, and circular radial ring portion 12 is fastened on the coil of strip end face, with the zone, outer end of packed steel coil.Circular radial ring portion 12 is to be made of double-deck plate, when making circular radial ring portion 12, at first determines its radical length, is that datum line forms first overlapping 14 to the back bending folding with its inside edge 13 then.In the ordinary course of things, first overlapping 14 free edge extends to axial annulus portion 11 parts, to increase the rigidity of this outer angle protecting ring 1.In order to increase the intensity of outer angle protecting ring 1, in radially the be provided with convex-concave portion 15 of circular radial ring portion 12 together with first overlapping 14.
Referring to Fig. 2, this figure provides the overall appearance structure of second embodiment of outer angle protecting ring of the packed steel coil that the utility model proposes.The outer angle protecting ring 1 that the structure of this outer angle protecting ring 2 and embodiment 1 are proposed is basic identical, different is in axial annulus portion 21 and the position of close circular radial ring portion 22 is provided with annular ridge 23, roll over formed second overlapping 24 and be provided with from outer edge to back bending at the end regions of its other end, second overlapping 24 radical length is much smaller than the radical length of axial annulus portion 21, make to form the channel-shaped portion 25 that the inflection limit by annular ridge 23 and second overlapping 24 constitutes on the outside face of axial annulus portion 21, this channel-shaped portion 25 can be used for laying strapping.Annular ridge 23 is to form naturally when rolling outer angle protecting ring 2, also can be specially rolling by specialized equipment.
