Abstract
The utility model relates to a self-plugging rivet which comprises a rivet body and a rivet core, wherein the rivet body is tubular; one end of the rivet body is provided with a rivet cap of a radial convex plate, and the outer surface of the other end of the rivet body is tapered; the diameter of the outer end of the rivet body is less than that of the inner end thereof; the diameter of the head of the rivet core is larger than the diameter of the outer end of the rivet body with taper; the lateral surface of the inner end of the head of the rivet core is a plane; when in riveting, the end parts of the rivet body are extruded, deformed and overlapped together to form a convex ring. The ends of the rivet body of the self-plugging rivet do not need to be propped open; the head of the rivet core can not deform and go into the rivet body either, thus avoiding the deformation of a riveting hole. The self-plugging rivet greatly improves the tensile property and shearing resistance, and can be used in occasions requiring higher riveting strength.
Description
(1) technical field
The utility model relates to a kind of rivet, particularly relates to a kind of self-plugging rivet.
(2) background technique
Rivet is in riveted joint, utilizes self deformation or interference to connect by the part of riveting parts.Commonly used have cup head, tack, sunk head rivet, self-plugging rivet, a tubular-shank rivet, and these normally utilize self deformation to connect by riveting parts.Common self-plugging rivet is made up of nail body and nail core, and nail body one end is provided with the nail lid, and nail core one end is provided with semicircle plush copper, and its other end does not have nail lid end from the nail body and inserts, and makes the nail body not have nail lid end and struts, thereby strut end and nail covers and will be clamped together by riveter spare by this.The nail body does not have nail Gai Yiduan in the process of strutting, its expansion might be created in the riveted holes of workpiece, makes riveted holes that deformation also take place, and makes the tension of this rivet, shearing strength reduce, then this rivet can not use in the place of having relatively high expectations, and using scope is restricted.
As the day for announcing be on June 21st, 2006 patent No. be 200520070744.7 Chinese utility model patent Stainless Steel Cup-shape Rivet, it comprises nail body and nail core, nail body one end circumferentially has the radially outer lug boss as the nail lid, one section diameter of nail core head is greater than other section, nail core afterbody does not have radially from the nail body, and outer lug boss one end penetrates in the nail body, be characterized in following closely core head and be the hollow core structures of cup shape for, the external diameter that this head is a section is respectively greater than other section diameter of nail core and the internal diameter of nail body.This Stainless Steel Cup-shape Rivet, though improved shearing resistance, tensility, but during riveted joint, still be make the nail core cup shape leading edge deformation and enter the nail body in, make and follow closely volumetric expansion, this mode still unavoidably makes the riveted holes distortion, thereby influences workpiece, still might come off under the vibration situation.
(3) summary of the invention
In order to overcome existing rivet when riveting, the nail volumetric expansion influences the riveted holes shape, and then reduces the deficiency of technology such as riveting intensity, and the utility model provides a kind of riveting intensity higher, and using scope is (a kind of) self-plugging rivet widely.
The technical scheme in the invention for solving the technical problem is:
A kind of self-plugging rivet, comprise nail body and nail core, the nail body is a tubulose, the one end is provided with the nail lid, nail lid is outer lug boss radially, and described nail body the other end outer surface is provided with tapering, and the diameter of its outer end is less than the diameter of the inner, the diameter of described nail core head is provided with the outer end diameter of tapering end greater than the nail body, and the interior end side surface of nail core head is the plane.
Nail core tail end does not have nail lid end from the nail body and inserts, and after the insertion, nail core head and nail core afterbody expose at nail external.During riveted joint, under the tension of nail core, because the diameter of nail core head is provided with the outer end diameter of tapering end greater than the nail body, and the interior end side surface of nail core head is the plane, the nail end of body is not to strut, and the nail core head also can't be out of shape and enters in the nail body, but the nail body is provided with the distortion that is squeezed of tapering end, overlaping becomes bulge loop, and workpiece promptly is clamped between bulge loop and the nail lid.Riveted holes after the riveted joint is also indeformable, and bulge loop is stronger than general its tension of distortion, shear behavior.Because some stays nail body inside riveted joint back nail core, its shear behavior also strengthens greatly.
Nail body endoporus is columniform step hole, and nail core middle part is provided with step, and the step at nail core middle part is suitable with the step hole of nail body.Establish step in the nail body, the corresponding step of establishing of nail core outer surface behind rivet, because the barrier effect of step can avoid rivet to come off, increases riveting intensity.
The nail core head is that cylindrical body and Rotary-table combine, and head the inner is a cylindrical body.
Nail core tail end is provided with anti-skidding silking, is provided with fracture port between the step at anti-skidding silking and nail core middle part.Anti-skidding silking can increase pulling force, prevents to skid, and after the riveted joint, disconnects at fracture port at the nail core.
The beneficial effects of the utility model are: the diameter of the utility model nail core head is greater than nail end of body diameter, and the interior end side surface of nail core head is the plane, the nail end of body distortion that is squeezed when then riveting, and overlaping becomes bulge loop.The utility model need not the nail end of body is strutted, and the nail core head also can't be out of shape to enter to be followed closely in the body, has then avoided riveted holes generation deformation.The utility model has improved tension and shear behavior greatly, can be used for the occasion that riveting intensity is had relatively high expectations.

Fig. 2 is the structural representation of the utility model nail core;
Fig. 3 is the structural representation after the nail core inserts the nail body;
Fig. 4 is the structural representation after the utility model riveted joint.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of self-plugging rivet comprises nail body 1 and nail core 2, and as shown in Figure 1, nail body is a tubulose, and an end is provided with nail and cover 3, is outer lug boss radially, and the nail body the other end is provided with tapering, and the diameter of outer end is cylindrical body less than the diameter of the inner in the middle part of the nail body, and following closely body endoporus 4 is step hole.As shown in Figure 2, nail core head 5 is made up of cylindrical body and Rotary-table, and Rotary-table is arranged on the outer end, and the diameter of Rotary-table bottom surface is identical with cylindrical diameter, and cylindrical diameter does not have the diameter of nail lid end greater than the nail body.Nail core middle part 6 is provided with step, and it is suitable with nail body step hole.Nail core afterbody is provided with anti-skidding silking 8, is provided with fracture port 7 between anti-skidding silking 8 and the step.Nail core tail end does not have cap end from the nail body and inserts, and as shown in Figure 3, after the insertion, nail core head and afterbody expose outside.During riveted joint, because the tension of nail core, cylinder diameter is greater than nail end of body diameter, and nail core end face is the plane, the extrusion of nail end of body, and the overlapping bulge loop that becomes, and workpiece just has been clamped between bulge loop and the nail lid firmly.The step of the step hole of nail body and nail core matches, and has increased riveting intensity, makes its difficult drop-off.
