The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, a kind of sedan-chair wall, the reinforced rib 2 that comprises wallboard 1, is arranged on wallboard 1 back side and extends along the short transverse of wallboard 1, reinforced rib 2 has two, two reinforced ribs 2 are provided with separately along the Width of wallboard 1, and each reinforced rib 2 extends to top ends from the bottom of wallboard 1.The dual-side of each reinforced rib 2 all by no rivet at wallboard 1 back side, the vertical continuous equally spaced riveting point of a row is set respectively on the dual-side of each reinforced rib 2.Wallboard 1 and reinforced rib 2 fix by riveted joint and are connected, and riveting operation is simple and convenient, and cost is low, and non-environmental-pollution to the panel surfaces zero damage, has been avoided follow-up surface treatment, enhances productivity.
In Fig. 2, the dual-side of reinforced rib 2 all by no rivet at wallboard 1 back side, the centre of reinforced rib 2 with respect to dual-side towards back side bending projection, the centre of reinforced rib 2 and dual-side by the projection the vertical surface transition.
In Fig. 3, utilize the back taper punch, wallboard 1 and reinforced rib 2 are passed through the punch process process by front to the back side, wallboard 1 and reinforced rib 2 are squeezed into corresponding die, under further squeezing action, the reinforced rib 2 of the wallboard 1 Extruding die side of punch side makes its flow deformation in die.Reinforced rib is extruded towards back side projection, projection 4 has the conical internal cavity 3 that enlarges gradually to the back side from the front, wallboard 1 with conical internal cavity 3 corresponding positions on be extruded and form tapered protrusion 6, projection 4 on the reinforced rib is fastened on the tapered protrusion 6 by conical internal cavity 3, and the conical outer surface of tapered protrusion matches with the cone-shaped inner surface of conical internal cavity and pushes against.The head edge of the projection 4 on the reinforced rib 2 axially stretches out along it, forms a circle bulge loop 5, and so promptly having produced one had not only had seamed edge but also carrot-free point of connection, and at the point of connection place, it is unstressed concentrating that material does not have the damage of tearing, so Joint strenght is high.
