Abstract
The invention discloses a riveting connecting piece, which comprises a connecting part and a riveting part, wherein a through threaded hole or a blind threaded hole is formed in the riveting connecting piece preferentially, and the inside diameter of the hole is smaller than that of the riveting part; naturally, the hole can be a through hole or a blind hole arranged in the riveting connecting piece so as to adopt other connecting modes; the connecting part is used for connecting other components, and the riveting part is used for riveting and tightening with a sheet material to be riveted; the riveting part is hollow inside and comprises a base part and a deformed riveting column; the deformed riveting column is of a short pipe shape, the bottom thereof is provided with annularly-distributed pointed teeth towards the outside to prevent rotation, one end face of the base part contacts with the sheet material to be riveted, the other end of the base part is connected with the connecting part, and the outside diameter of the pointed teeth is smaller than that of the base part; the material of the riveting connecting piece is a plastic deformation material of which the strength is higher than that of the sheet material to be riveted, and the material is preferably stainless steel, or other metallic materials or nonmetal materials. The riveting connecting piece not only has stronger axial bearing capacity, but also has stronger radial twisting resistance, thus the riveting is firmer.
Description
Technical field
The present invention relates to a kind of fastening connection piece, be specifically related to a kind of riveting connector.
Background technique
At present; Riveted fastening connection piece commonly used is mostly basically to be the structure that presses, and like circular self-clinching nut, self-clinching nut is put in advance the metal blank (sheet thickness is slightly larger than the self-clinching nut shoulder height) towards good circular hole (Circularhole diameter and self-clinching nut diameter are Spielpassung); Because of the intensity of self-clinching nut greater than metal blank; Through the extruding of upper die and lower die, metal blank receives the extruding of pointed tooth, and material is pressed into the position, taper space of nut; Thereby nut and plate are riveted together, and the pointed tooth of nut can prevent that nut from rotating; This structure radially twisting strength is higher, but axially stretching resistance a little less than, easily nut is ejected when therefore playing screw and comes off.
Summary of the invention
Technical problem to be solved by this invention provides a kind of stretching resistance simple in structure, axial and reaches the radially all higher riveting connector of twisting strength.
The technological scheme that the present invention adopted is: riveting connector, comprise joint and riveting part, and preferably be provided with logical tapped hole or blind tapped hole in it; And internal diameter is less than the riveting part internal diameter, can certainly be to be provided with through hole or blind hole in it to adopt other Placements, and said joint is used for being connected with miscellaneous part; Said riveting part is used for and treats that the riveted panel clinching is fastening, its interior hollow of said riveting part, and said riveting part comprises base portion and distortion riveting column; Said distortion riveting column is the short tube shape, and the bottom outwards is provided with the annular distribution pointed tooth in order to anti-rotation, and said base portion one end face contacts with treating riveted sheet material; The other end is connected with joint; The pointed tooth external diameter is less than the base portion external diameter, and said riveting connector material is the material of plastically deformable, and intensity is higher than and treats riveted sheet material; Material is preferably stainless steel or free-cutting steel, also can be other metallic material or nonmetallic material.
Logical tapped hole of establishing in the said joint or blind tapped hole, or through hole or blind hole, and be the conical surface transition between the endoporus of riveting part, or the step surface transition
In the such scheme, said base portion external frame is preferably circle or regular polygon, can certainly be other shapes, and said joint external diameter is less than or equal to the base portion external diameter.
In the such scheme; Said distortion riveting column preferred heights is greater than treating the riveted sheet metal thickness; Patrix can adopt the dull and stereotyped riveting column that directly will be out of shape to exceed the part of treating the riveted sheet metal thickness and clamp-on counterbore and outside spreading like this; Certainly distortion riveting column height also can be less than or equal to and treats the riveted sheet metal thickness, and then patrix need be made a protrusion frustum and will be out of shape the riveting column spreading this moment.
The invention has the beneficial effects as follows: the present invention adopts and not only to press but also the structure of the riveting of rising, before the riveted with plate bottom outlet elder generation counterbore, through the extruding of upper die and lower die; Pointed tooth is pressed in the plate, and the distortion riveting column outwards is squeezed in the counterbore spreading (material is cancelled because of even distribution to enterolithic radial stress), and the riveting and pressing of rising is accomplished in once-through operation; Can the advantage of two kinds of structures be integrated in one; Both obtained bigger axial bearing capacity, obtained bigger radially twisting resistance again, and made riveted joint more firm.
