Preferably, the described conical surface rushing Insert Nut joint is provided with multiple plane.
Preferably, the mounting hole diameter on described metal substrate is identical with the stub end diameter rushing Insert Nut joint.
Preferably, described projection of rushing in the nut head of Insert Nut is provided with 6 ~ 10.
As mentioned above, a kind of nut of the utility model rushes riveting knot structure, has following beneficial effect:
Working principle of the present utility model is that the Insert Nut that liquidates applies an external force, is punched in metal substrate, make metal substrate produce distortion and with rush Insert Nut and to combine together formation assembly.Join strength of the present utility model is high, good rigidly, precision are high.Do not need other additional materials, be conducive to alleviating overall weight, its join strength is greater than Maximum Torque when dimension bolt screws, and efficiently solves the some shortcomings in tratitional technology, for automotive light weight technology technology has made contribution.

Embodiment
The structure that Figure of description illustrates, ratio, size etc., content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop in scope that technology contents that the utility model discloses can contain.Simultaneously, quote in this specification as " on ", D score, "front", "rear", the term such as " centre ", also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1-Figure 3, a kind of nut of the utility model rushes riveting knot structure, and comprise metal substrate 1 and rush Insert Nut 2, described metal substrate 1 has mounting hole 11, and the described Insert Nut 2 that rushes comprises nut head 21 and joint 22.As shown in Figures 2 and 3, the described Insert Nut 2 that rushes has the tapped hole 23 running through nut head 21 and joint 22, described joint 22 is the truncated cone shape comprising little head end 221 and stub end 222, described little head end 221 is fixedly connected with nut head 21 bottom surface, described nut head 21 bottom surface is circumferentially provided with multiple projection 211 spaced apart, described protruding 211 radially raise from inside to outside gradually, and namely the described bottom surface of protruding 211 is inclined-planes, protrude higher near nut head 21 marginal position.The mounting hole 11 of the described joint 22 and metal substrate 1 that rush Insert Nut 2 matches, and then realizes rushing being fixedly connected with of Insert Nut 2 and metal substrate 1.
Processing method of the present utility model is: located by the counterdie that metal substrate 1 puts into stamping press, to Insert Nut 2 joint 22 be rushed put into the mounting hole 11 of metal substrate 1 down, counterdie is connected with the table top of stamping press, patrix is connected with the top of stamping press.Open stamping press, the top of stamping press is poured rushing Insert Nut 2 in metal substrate 1 with patrix.Rush that Insert Nut 2 is easier to be poured in metal substrate 1 to allow, mounting hole 11 diameter on described metal substrate 1 is identical with stub end 222 diameter rushing Insert Nut 2 joint 22.Along with the carrying out of punching press, projection 211 in described nut head 21 can be embedded in metal substrate 1 because of pressure effect, projection 211 in the utility model is the structures radially raised gradually from inside to outside, so be embedded into after in metal substrate 1 protruding 211, metal substrate 1 can be out of shape because of the pressure effect of protruding 211 bottom surfaces, namely a part for metal substrate 1 can be compressed by protruding 211 to the inside, can be abutted in by the part compressed on the conical surface rushing Insert Nut 2 joint 22, namely rush Insert Nut 2 to be embedded in metal substrate 1 and to combine together with metal substrate 1, and then realize rushing Insert Nut 2 and axial motion can not occurring opposing metallic substrate 1.In addition, because multiple protruding 211 all can be embedded in metal substrate 1 because of pressure effect, rush Insert Nut 2 rotate in mounting hole 11 so can limit, realize stable being connected to form an assembly, when this assembly and other Assembly of the parts, bolt rushes Insert Nut 2 when rushing the tapped hole 23 of Insert Nut 2 when screwing in along with screws, and then can not ensure reliable and stable service behaviour.
In the present embodiment, relatively rotate with metal substrate 1 to prevent rushing Insert Nut 2 further, the described conical surface rushing Insert Nut 2 joint 22 is provided with multiple plane 223, when metal substrate 1 is out of shape, part metal substrate 1 can be pressed against in each plane 223, and then raising stability, prevent rushing Insert Nut 2 and rotate.
In the present embodiment, described projection 211 of rushing in the nut head 21 of Insert Nut 2 is provided with 6 ~ 10, wherein preferably 8.
Metal substrate described in the utility model can be aluminum-magnesium alloy plate or other metallic material such as alloy sheets, steel plate.
In sum, a kind of nut of the utility model rushes riveting knot structure, can solve metal substrate and the problem of rushing Insert Nut and be connected instability.So the utility model effectively overcomes practical problems more of the prior art thus has very high value and use meaning.
Above-mentioned mode of execution is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.The utility model also has many aspects can improve under the prerequisite of overall thought, all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or change for person skilled in the art scholar.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
