Embodiment
For the benefit of to the understanding of structure of the present utility model, be described below in conjunction with drawings and Examples.
With reference to Fig. 1, it is the view before not riveting in the utility model cover plate riveting structure.With reference to Fig. 2, it is the side-looking structural representation of riveted joint bolt in Fig. 1.With reference to Fig. 3, for riveting the plan structure schematic diagram of seat in Fig. 1.
Shown in composition graphs 1 to Fig. 3, the utility model provides a kind of cover plate riveting structure, comprising: the cover plate plate 1 of bending, comprises multiple riveted holes; Special riveted joint bolt 2, comprise screw rod 20 and spiral shell head 22, screw rod 20 is provided with bulge loop 24; Riveted joint seat 3, comprise jack 30 and flange 32, flange 32 coaxial rings is located at around the aperture of jack 30, the internal diameter of flange 32 is greater than the external diameter of bulge loop 24, to ensure that screw rod 20 can insert in jack 30 completely, cover plate plate 1 is placed on riveted joint seat 3, and the screw rod 20 of riveted joint bolt 2 is arranged in riveted holes and punching press is downwards inserted in jack 30, and mating flange 32 reaction force upwards causes the inner edge extrusion-deformation of riveted holes and then tight riveting between bulge loop 24 and the spiral shell head 22 of riveted joint bolt 2.
As Fig. 1, particularly, the surrounding of riveting seat 3 is installed with guide pillar 34, one pressing base 4 is movably set on guide pillar 34, pressing base 4 comprises downward pressing surface and is positioned at the guide pillar hole of surrounding, and guide pillar 34 is arranged in guide pillar hole, and pressing surface top is pressed on the spiral shell head 22 of riveted joint bolt 2.
As Fig. 2, particularly, the screw rod 20 of riveted joint bolt 2 has thread section, bulge loop 24 ring is established and is fixed between thread section and spiral shell head 22, and then forms groove 26 between bulge loop 24 and spiral shell head 22.Comparatively preferably, spiral shell head 22 is provided with multiple anti-skidding salient point 28 towards the surface uniform of thread section, to produce anti-skidding effect to spiral shell head 22 when squeezed riveting.
After having said structure feature, shown in composition graphs 1 to Fig. 5, the utility model can by following implementation Process:
A. as Fig. 1, provide a set of matching die with above-mentioned riveted joint seat 3 and pressing base 4, wherein, riveted joint seat 3 is as counterdie, and pressing base 4 is as patrix.Be arranged on the riveted holes of cover plate plate 1 by above-mentioned special riveted joint bolt 2, then be placed on by cover plate plate 1 on riveted joint seat 3, wherein, screw rod 20 correspondence of riveted joint bolt 2 is arranged in the jack 30 of riveted joint seat 3;
B. as Fig. 4, seat 3 and pressing base 4 matched moulds will be riveted, by matched moulds punching press, coordinate flange 32 on riveted joint seat 3 directly by riveted joint bolt 2 squeezed riveting in the riveted holes of cover plate plate 1;
