Embodiment
Preferably mode of execution of the present invention is described below.
Fig. 3, Fig. 4 are the stereograms that represents the first mode of execution of the present invention.Penetrating type nut of the present invention is also identical with penetrating type nut in the past, has: the periphery circular protrusion 2 in the outstanding lower surface periphery that is arranged on nut main body 1; Interior all circular protrusions 3 of the outstanding lower surface central authorities that are arranged on nut main body 1; And be formed on the riveted joint groove 4 between this periphery circular protrusion 2 and interior all circular protrusions 3.Interior all circular protrusions 3 are side-prominent larger downwards than periphery circular protrusion 2.In addition, the internal surface of interior all circular protrusions 3 is formed with internal thread 7, and it is for carrying out fastening other parts with bolt, and this is self-evident.
The plane of inclination that the inner peripheral surface 8 of periphery circular protrusion 2 is tip side (lower end side) undergauges, the outer circumferential face 9 of interior all circular protrusions 3 is corresponding thereto barrel surface.Therefore the cross section that, is formed on the riveted joint groove 4 between periphery circular protrusion 2 and interior all circular protrusions 3 is narrow, the inboard roomy shape of tip side.In addition, in the present embodiment, the outer circumferential face 10 of periphery circular protrusion 2 is also plane of inclination.
Be formed with at the top end of this periphery circular protrusion 2 translot 11 that multiple oil extractions are used.In the present embodiment, the number of translot 11 is four, and with 90 ° of arranged spaced.As previously mentioned, preferably 2～8 of the numbers of translot 11.
In the present embodiment, translot 11 is that cross section is the groove of V word shape, and the degree of depth of this translot 11 is 0.3～1.0mm.If the degree of depth is shallower than 0.3mm, the discharge effect of oil is insufficient, and on the contrary, if the degree of depth is deeper than 1.0mm, not only the intensity of periphery circular protrusion 2 declines, and manufacture cost increases.This translot 11 is to form by the top end of peripheral ring shape projection 2 is carried out to punching press, thus preferably V word shape of groove shape, even but the groove of U-shaped or slit-shaped is also harmless.
In the present embodiment, be on plane of inclination, to be formed with the sawtooth 12 that spline is used at the inner peripheral surface 8 of peripheral ring shape projection 2.The sawtooth 12 of present embodiment is that cross section is the ridge of V word shape, but the shape of sawtooth 12 is not particularly limited.
The penetrating type nut of the present invention forming is like this identical with conventional art, a kind ofly utilize drift and be driven into the penetrating type nut of the sheet metal 6 being placed on punch die 5, but, have under a large amount of oil conditions in the surface attachment of sheet metal 6, the oil in the inside of riveted joint groove 4 after pressurized can be as shown in Figure 6 sprays to outside from the translot 11 of the top end that is formed at periphery circular protrusion 2.Therefore, can as shown in Figure 2 innage not pressed to the inside that is enclosed in riveted joint groove 4.So, even if penetrating type nut of the present invention is arranged on surface with on the sheet metal 6 of large gauging time, also can make as shown in Figure 6 metal fully flow into the whole inside of riveted joint groove 4, the decline of riveting intensity is extremely small.
And as shown in the embodiment, if be formed with at the inner peripheral surface 8 of peripheral ring shape projection 2 sawtooth 12 that spline is used,, in the inside of riveted joint groove, metal can engage securely with sawtooth 12, can obtain more excellent spline effect.Therefore, the penetrating type nut (being formed with the translot 11 that four degree of depth are 0.5mm) of present embodiment, even if be arranged on surface with on the sheet metal 6 of large gauging time, that lashing force only drops to than drying regime is about 80%, idling torque only drops to about 90%, drop to 30% with lashing force, idling torque drop to 40% without compared with the product in the past of translot, the penetrating type nut of present embodiment has the effect that intensity increases substantially, and this point has obtained confirmation.
In above-described the first mode of execution, be only formed with at the top end of peripheral ring shape projection 2 translot 11 that oil extraction is used, and the second mode of execution is as shown in Figure 7 such, also can be formed with the pod 13 that multiple oil extractions are used at the outer circumferential face of interior all circular protrusions 39.So,, if be also formed with pod 13 at the outer circumferential face 9 of interior all circular protrusions 3, the oil after the inside of riveting groove 4 is pressurized also can be discharged from from these pods 13, can obtain more excellent effect.But the oil extraction effect of bringing due to translot 11 is large, the situation that pod 13 is only set therefore cancel translot 11 is also not preferred.
As mentioned above, even if having advantages of to be arranged on, penetrating type nut of the present invention while being attached with on oily sheet metal 6, also can obtain excellent riveting intensity.Therefore, needn't from sheet metal 6 surfaces, oil be erased in advance, can improve operability.
