Embodiment
Below will clearly demonstrate this novel spirit with accompanying drawing and detailed description, have in the technical field under any and know that usually the knowledgeable is after understanding this novel preferred embodiment, when can be by the technology of the utility model institute teaching, change and modification, it does not break away from spirit of the present utility model and scope.
With reference to Fig. 3 A to Fig. 3 C, it illustrates plane type sealing riveting structure one embodiment of the present utility model respectively in the difference sectional view in assembling stage.Among Fig. 3 A, plane type sealing riveting structure 200 includes first sheet material 210 and second sheet material 220, wherein has on first sheet material 210 on perforation 212, the second sheet materials 220 and has boss 222.Has chamfering 214 on the plate edge around the perforation 212.The outside diameter d 1 of boss 222 is roughly the same with the inner diameter d 2 of perforation 212.The height h1 of boss 222 then is the height h2 greater than perforation 212.Boss 222 is hollow boss, and boss 222 has cavity 224.
Among Fig. 3 B, the boss 222 on second sheet material 220 passes the perforation 212 on first sheet material 210, and this moment, boss 222 had one little section surface that protrudes in first sheet material 210, can have gap g between chamfering 214 and the boss 222.Lower die head 300 stretches in the cavity 224 of boss 222, and to locate first sheet material 210 and second sheet material 220, lower die head 300 also provides support power.310 of last die heads be with respect to lower die head 300 fast and the powerful underground row of compressing into press, by the external force that last die head 310 impacts downwards, the part that makes boss 222 protrude in first sheet material 210 produces deformation.
Boss 222 among Fig. 3 B is deformed into boss 222a shown in Fig. 3 C because of being subjected to external impacts.Boss 222a can fill up the other gap g (seeing Fig. 3 B) of the perforation 212 of first sheet material 210 and chamfering 214 after punching press, make the wedge-shaped bead 216 that is formed with coupling chamfering 214 on the boss 222a.Boss 222a has wedge-shaped bead 216, and wherein boss 222a is embedded in perforation 212, and wedge-shaped bead 216 chimeric chamferings 214 realize the sealed type riveted joint.Wedge-shaped bead 216 compactings first sheet material 210 is to limit the displacement of first sheet material 210.
Owing to have chamfering 214 around the perforation 212 on first sheet material 210, boss 222a is provided the required space of material of distortion, fill up chamfering 214 other gap g behind the boss 222a riveting and formed wedge-shaped bead 216, make sheet material 210 surfaces of winning to be similar to smooth, the outward appearance of product is comparatively smooth attractive in appearance, and is difficult for and other assemblies interfere.And the interlock of passing through between wedge-shaped bead 216 and the chamfering 214 promotes the pulling force and the soundness of riveting.
With reference to Fig. 3 A to Fig. 3 C.Boss 222 can be integrally formed on second sheet material 220 by the anti-mode of second sheet material 220 of drawing, and the outside diameter d 1 of boss 222 is decided by to bore a hole 212, adjusts the boss 222 that pulling force comes moulding different heights h1 according to the product specification demand.Make boss 222 produce deformation by the preparation process that presses in addition, make wedge-shaped bead 216 be integrally formed on the boss 222a.This plane type sealing riveting structure 200 has realized no riveted joint, directly utilizes corresponding structural riveting on first sheet material 210 and second sheet material 220, can save cost of material effectively.
The inwall corner of boss 222 has fillet 228 (R angle), and fillet 228 can form when drawing second sheet material 220 to form boss 222 in the lump counter.Fillet 228 and wedge-shaped bead 216 lay respectively at the relative both sides of boss 222a.Fillet 228 can be difficult for rupturing because of stressed so that the molding effect of boss 222a is better.
Boss 222 is the face of pressing 230 towards first sheet material 210 in order to the one side that contacts with last die head 310, last die head 310 preferably can have the slightly surface of projection, force wedge-shaped bead 216 and chamfering 214 to closely cooperate, this moment is pairing, and the face 230 that presses is the cambered surface of indent slightly.Can have more salient point 312 on the last die head 310, on the face of pressing 230, forming indenture 232, the buffering that indenture 232 can be when stressed.The face that presses 230 and the impression 232 of indent can increase the riveted joint dynamics of plane type sealing riveting structure 200 and promote its riveting intensity.
By above-mentioned the utility model preferred embodiment as can be known, application the utlity model has following advantage.Plane type sealing riveting shaping structures is simple, riveting intensity is good, the cost of material is low, have good sealing property, and the face that presses can not protrude from sheet material, makes that outward appearance is more attractive in appearance and can avoid interfering with other assemblies.
