Definitions

  • ABSTRACT OF THE DISCLOSURE A self-staking insert having a polygonal shank wherein the sides are planar and adjacent sides of the polygon are joined by arcuately curved surfaces so as to provide a continuous peripheral surface which approaches circularity, a bulge portion at the leading end of the shank which is wider than the receiving hole if prepunched and which tapers to a circular end face.
  • the present invention relates to a metal insert for sheet or plate members and more particularly to a self-staking type of insert.
  • a portion of the insert is received in an opening the plate or sheet member and another part of the insert indents the sheet or plate member to cause material to flow around the first part to securely hold the insert against both removal and rotation.
  • Certain structures of the prior art have utilized inserts with sharp edged grooves or knurls which bite into the material of the sheet or plate member for holding the insert against removal and rotation relative to the member. Such sharp edged structures cause stress concentrations in the sheet or plate which cause early propagation of fatique cracks when the plate or sheet member is dynamically loaded.
  • the structures have not been adapted for use as punches and have not provided an noncircular body configuration where metal is flowed into substantially full circumferential contact with the body.
  • An object of the present invention is to provide a new and improved insert such as an internally threaded fastener of the self-staking type which may be used with a prepunched hole or to punch its own receiving opening in a plate or sheet member and which, when inserted, is held against rotation in the sheet or plate member, the insert being so constructed and arranged that stress concentrations in the plate or sheet member are kept to a minimum thus providing a strong assembly having a high fatigue life capability.
  • a new and improved insert such as an internally threaded fastener of the self-staking type which may be used with a prepunched hole or to punch its own receiving opening in a plate or sheet member and which, when inserted, is held against rotation in the sheet or plate member, the insert being so constructed and arranged that stress concentrations in the plate or sheet member are kept to a minimum thus providing a strong assembly having a high fatigue life capability.
  • a further object of the present invention is to provide a new and improved metal insert, such as an internally threaded fastener, of the self-staking type for assembly into a sheet or plate member, the insert having a central projecting portion of polygonal configuration and a head portion for flowing the metal of the sheet or plate member into contact, preferably full circumferential contact, with the polygonal central portion as the insert is assembled to the member with the insert being such that it is securely held against rotation and stress concentrations in the sheet or plate member are minimized thus providing a strong assembly having a high fatigue life capability.
  • a new and improved metal insert such as an internally threaded fastener
  • a further object of the present invention is to provide a new and improved insert having a projecting central portion adapted to be inserted into a prepunched hole in a sheet or plate member for receiving the insert or to punch a receiving opening in the sheet or plate member in cooperation with a conventional die with the insert being so constructed and arranged that maximum strength for punching purposes is obtainable in the projecting portion and the insert is securely held against rotation while 3,399,705 Patented Sept. 3, 1968 the stress concentrations in the final assembly are held to a minimum.
  • a further object of the present invention is to provide a new and improved insert of the self-staking type in which a central projecting portion has a polygonal shape with the shape approaching that of a circle to provide maximum punching strength and to avoid setting up unnecessary stress concentrations and yet having sufiicient angularity between the sides to securely hold the insert against rotation in a plate or sheet member.
  • a further object of the present invention is to provide a new and improved self-stacking insert, such as an internally threaded fastener, which has a projecting portion adapted to be received in a prepunched hole of a nominal diameter in a parent member to which it is to be assembled or to be used as a punch for punching a receiving opening in cooperation with a standard circular die, the insert being so constructed and arranged that the projecting portion will hold the insert against rotation when inserted into a sheet or plate member with or without a prepunched hole and so that maximum strength can be obtained in the projecting portion.

  • the insert shown therein is a self-staking nut 10 having a head portion 12 and a central projection 13 adapted to be received in a prepunched opening or in a self-punched opening in a sheet or plate member into which the nut is to be attached.
  • the head portion 12 extends laterally outwardly of the projection 13 at one end of the nut and a tapped opening 14 extends axially through the head portion 12 and the central pro jection 13.
  • the outer side of the head portion 12 of the nut is considered the top of the nut.
  • the central projection 13 of the nut has a shank portion 13a which joins the head portion 12.
  • the shank portion 130 in cross section, has a polygonal configuration providing a continuous peripheral surface which is adapted to hold the nut against rotation when the nut is inserted into a plate or sheet member.
  • the polygonal configuration is that of a regular polygon having included angles between adjacent sides which are obtuse.
  • the regular polygon is such that a circle inscribing the polygon has a diameter no smaller than of the diameter of the circle circumscribing the polygon and the diameter is no greater than that which will provide a three-thousandths inch clearance as a minimum between a side of the polygon and the circle circumscribing the polygon.
  • the included angle between adjacent sides of the polygon may be as small as about 100 but preferably the shank portion 13a is at least hexagonal so that the included angle between adjacent sides is 120. It will be noted that in the type of regular polygon described, the sides of the polygon form chords of the circle circumscribing the polygon.
  • the sides of the polygonal shank portion are planar, adjacent sides are joined by arcuately curved surfaces which provide the aforementioned continuous peripheral surface.
  • the self-staking nut could be constructed, for example, by providing a continuous peripheral surface on the body thereof which is configured to provide a sinusoidal periphery.
  • the peripheral surface is termed continuous, since the shank portion is constructed so that there is no point on the periphery formed by the intersection of planar surfaces, that is, there are no portions of the periphery formed by a line.
  • the lower end of the polygonal shank portion 13a flares out outwardly and blends with a bluge portion 18 on the central projection.
  • the polygonal sides of the shank portion 13a preferably extend along the bulge portion 18 to a point at which the diametrical extent of the bulge is maximum.
  • the bulge 18 therefore has the same general cross-sectional configuration as the shank portion 13a.
  • the central projection tapers from the bulge portion 18 to the outer end face 20 of the projection.
  • the outer end face of the projection 13 is preferably more circular than the polygonal part of the projection and in the preferred and illustrated embodiment the portion of the projection immediately adjacent the outer end is generally frustoconical in configuration and tapers outwardly to the maximum transverse dimension of the projection at the bulge 18.
  • the taper of the frusto-conical portion preferably extends at a maximum angle of about with respect to the axis of the tapped opening. It will be noted that the tapered portion extends higher at the corners of the polygon than at the flats.
  • the underside of the head portion 12 includes a planar circumferentially continuous surface engageable with the plate or sheet member as the nut is inserted therein to effect flowing of the material of the plate or sheet into engagement with the periphery of the projection 13.
  • the underside of the head portion 12 is provided with an annular recess 22 immediately adjacent the central projection 13 which defines an indenting flange 23 having an annular surface 23a immediately outwardly of the recess 22.
  • the recess 22 opens downwardly and the bottom thereof curves upwardly away from the annular surface 23a and then downwardly to blend with the central projection.
  • the radius of curvature of the bottom of the curved recess is smaller immediately adjacent the projection and becomes progressively larger to provide a side surface 24 on the indenting flange which extends inwardly from the annular surface 23a and which is inclined to face toward the central projection 13.
  • the central projection 13 is designed so that the maximum transverse dimension of the polygonal shank portion 13 is approximately the same or even somewhat larger than the maximum transverse dimension of the outer end face 20.
  • the outer end face is, as mentioned above, dimensioned such that it will fit into a prepunched hole with which the nut is designed to be used and is preferably substantially circular.
  • the frusto-conical portion 21 will cause the material of the parent member to compress to allow the bulge 18 to pass through the material and the indenting flange 23 of the head portion will engage and indent the material of the sheet or plate member M to cause the material to flow around the polygonal shank portion of the nut.
  • the recess 22 causes the indenting forces to be concentrated at the annular bearing surface 23a on the in denting flange and this surface is designed to have an area such that the normal punching pressure will overcome the yield resistance of the material to permit the indenting flange 23 to indent itself into the material and to flow the material laterally to flow around and engage the polygonal projection 13 for substantially the entire circumferential extent thereof.
  • the inclined surface 24 of the indenting flange 23 will aid in directing the flow of material inwardly against the polygonal portion.
  • annular surface 23a is, in the preferred embodiment, a continuous surface and therefore when the indenting flange is indented into the sheet or plate member, it not only causes .a flow into engagement with the projection for substantially the entire circumferential extent of the projection but it does not tend to set up undesirable stress concentrations in the receiving member.
  • the nature of the polygonal central projection 13 is such that the adjacent sides do not define sharp corners which tend to set up stress concentrations.
  • the included angles between the sides of the central projection 13 are obtuse angles which tend to minimize stress concentrations. While the central projection preferably approaches circularity, the angle between adjacent sides is such that the projection will securely hold the nut against rotation in the sheet or plate member.
  • the length of the projection 13 is such that the end face 20 is preferably flush with or within the sheet or plate member when the nut is inserted into the member as is shown in FIG. 3. During insertion, the nut is backed by an anvil 26 or die member.
  • a self-staking nut embodying the present invention may be modified for use with the parent member having a counter-sunk receiving opening.
  • a modified nut is illustrated in FIG. 8.
  • the nut 10 comprises a head portion having an indenting flange 23' which is formed to permit the nut, in its assembled condition, to be flush with the surface of a sheet or plate member having a prepunched counter-sunk receiving opening.
  • the indenting flange 23' includes a continuous annular bearing surface 23a' extending between the projection 13' and an upwardly diverging frusto-conical surface 23b which is formed to correspond with the frusto-conical countersunk receiving opening in the parent member.
  • the bearing surface 23a provides a controlled indenting area such that as the nut is advanced into the receiving opening the bearing surface will engage and indent the frusto-conical wall of the counter-sunk opening to flow the material of the parent member into engagement with the periphery of the projection 13'.
  • the projection 13' of the nut 10' is of the same construction as the projection 13 of the nut 10, previously described.
  • Conventional dies and punches are commonly used to pre-punch openings in sheet metal or plate members for receiving the nuts.
  • the nut itself may be used with the conventional punch die to punch the receiving opening for the nut as is illustrated in FIG. 4.
  • the punch die will have a nominal opening approximately the same as the nominal opening of the opening to be punched and the outer end face 20 of the polygonal projection 13 is designed to cooperate as :a punch with the punch die.
  • the outer end portion of the central projection is preferably more circular than the polygonal shank portion and the circularity is such that the clearance between the outer end of the projection and circular die is preferably not more than 10% of the thickness of the sheet material to assure clean punching. It will be understood that the projection 13 is not actually received in the die during punching since it does not project outwardly of the plate or sheet member. The clearance specified however is lateral clearance which would be present if the outer end of projection were disposed at the outer end of the opening in the punch die.
  • the nut is preferably a cold forged nut.
  • One of the problems confronting the industry in forming a cold forged nut as described is the problem of providing both the head portion and the bulge 18.
  • the nut may be formed by first cold forging a metal slug in a die cavity to form a blank 29 with the general exterior configuration of the nut without the bulge 18 but with an axially extending skirt 32 which is polygonal in configuration to correspond to the shank portion.
  • a die cavity 30 which has a configuration for forming, in cooperation with a punch 31, a blank 32 having the exterior configuration of the nut without the bulge 18.
  • the die cavity has a polygonal recess 33 in the bottom of the die cavity and forming an extension of the sides of the cavity for forming the axially extending polygonal skirt 32a about the periphery of the outer end of the central projection of the nut blank which is to be upset to form the bulge 18.
  • the punch member in cooperation with a projection in the die cavity also forms the central opening through the blank except for a web portion 35.
  • the blank formed in the die cavity 30 is removed from the die cavity 30 by moving the blank axially out of the cavity and the web portion may then be removed by a suitable punching operation.
  • the skirt is upset with an upsetting member 36 which is moved against the end of the blank while the sides of the blank are substantially unrestrained.
  • the upsetting member is illustrated in FIG. 6 and has a flanged portion defining the 15 taper to control the flow of the material in the skirt to form the bulge.
