Description

Technical Field

[0001] This utility model relates to the field of sheet metal machinery technology, and in particular to a corrugated board core with a lantern-shaped structure. Background Technology

[0002] Currently, the conventional corrugated core used in light truck cargo boxes is formed by unfolding steel coils and then bending or rolling them multiple times. The corrugations are periodically distributed, and the joints between the corrugations are transitioned by rounded corners with a small radius (R value). This type of corrugated core has a relatively short service life. Therefore, a new type of corrugated core structure is designed to improve its performance and meet practical needs.

[0005] A corrugated core with a lantern-shaped structure includes a core body; the core body is a corrugated structure with multiple sets of base planes and convex surfaces arranged alternately, the convex surface includes an outward convex arc and an inclined surface, and the outward convex arc is connected to the adjacent base plane through the inclined surface.

[0006] Preferably, the convex arc is axially symmetrical with the two adjacent inclined surfaces.

[0007] Preferably, the convex surface further includes a concave arc; the convex arc and the inclined surface are connected by the concave arc.

[0008] Preferably, the two concave arcs on the convex arc are axially symmetrical.

[0009] Preferably, the concave arc, the convex arc, and the inclined surface are connected and transitioned by rounded corners.

[0010] Preferably, the concave arc and the fillet radius are equal.

[0011] Preferably, the core of the board is a roll-formed structure.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This utility model adopts a lantern-shaped corrugated core with a beveled transition at the joint between the corrugations, which improves the fatigue life compared to similar products on the market and meets the current market demand. Attached Figure Description

[0022] like Figure 1-4 As shown: A corrugated core board with a lantern-shaped structure includes a core body 1; the core body 1 is a corrugated structure with multiple sets of base planes 11 and convex surfaces arranged alternately. The convex surfaces include convex arcs 12 and inclined surfaces 14, and the convex arcs 12 are connected to adjacent base planes 11 by the inclined surfaces 14. The joints between the corrugations adopt an inclined transition, resembling a lantern-shaped structure, which improves the fatigue life of the service.

[0023] The convex arc 12 is axially symmetrical with the two adjacent inclined surfaces 14. Preferably, the radius R1 of the convex arc 12 is 85-90 mm.

[0025] The two concave arcs 13 on the convex arc 12 are axially symmetrical.

[0026] The concave arc 13, the convex arc 12, and the inclined surface 14 are connected by rounded corners. Three small rounded transitions are added at the junction of the inclined surface 14 and the convex arc 12, further forming a lantern-shaped structure, improving fatigue life. Compared to similar products on the market, the service life is increased by 150%, and the plate has a better appearance quality, meeting current market demands.

[0027] The concave arc 13 and the fillet radius are equal. That is, the radius R2 of the concave arc 13, the radius R3 of fillet 15, and the radius R4 of fillet 16 are equal, and the arc of fillet 15 and fillet 16 is 60°; in addition, preferably, a circle is drawn with the intersection of the base plane 11 and the inclined plane 14 as the center and the distance from the intersection to the center of the concave arc 13 as the radius, and the radius R5 is 48mm.

[0028] The core body 1 is a roll-formed structure. The base plane 11, the inclined plane 14, the convex arc 12, the concave arc 13, the fillet 15, and the fillet 2 16 are connected in sequence.
