摘要： A rivet guide head that guides a rivet during a rivet machine drive stroke is provided. The rivet guide head includes a rivet guide body having a rivet guide surface defined along a rivet guide bore having a guide bore axis. A first elongated guide pin is disposed in the rivet guide head that extends along a first guide pin axis and has an outer engagement surface. The guide bore axis is substantially parallel to the first guide pin axis. The rivet guide head is configured to guide the rivet along the outer engagement surface of the first elongated guide pin during the drive stroke. According to further aspects, the first elongated pin deflects laterally outwardly during the drive stroke. A first biasing member is disposed in the rivet guide head and is configured to bias the elongated guide pin in a direction toward the guide bore axis.

摘要： A rivet machine is provided. The rivet machine employs a die including a die body that has an inner wall with a pair of retaining ribs or projections extending inwardly therefrom. In use, the rivet pushes a slug from a workpiece within which it is mounted and into an opening of the die. The projections engage and retain the slug within the inner wall. According to further aspects, the pair of retaining ribs are diametrically opposed around the inner wall. Each of the retaining ribs has two converging surfaces that form an angle of between 90 and 150 degrees. In yet another aspect, the projections can be discontinuous such that a first retaining rib is longitudinally offset on the inner wall from a second retaining rib.

摘要： There is disclosed an improved apparatus for joining a plurality of pieces of sheet metal or other sheet material items by first drawing and then laterally extruding portions of the material to be joined into an enlarged shape which will permanently mechanically interlock the sheet material pieces. The apparatus utilizes a novel die construction in which portions thereof are resiliently biased toward one another and pivot and/or slide laterally outwardly in response to lateral extrusion of the joining material, and which is applicable to conventional "lanced" type joints as well as to a novel leakproof joint.

摘要： A new punch anvil is provided for use with an axial punch for use in a fastening system of the kind in which the punch displaces a portion of one sheet member, such as a thin metal sheet, into another sheet to fasten them together, the punch and die cooperating to form a "button" of sideways displaced material that locks the sheets together. The anvil consists of two parts, one of which is of smaller transverse dimension than the other to form a transverse shoulder between them. The anvil end against which the members are clamped to be punched is surrounded by a jaw which is split longitudinally to be in at least two members held assembled by an encircling resilient ring or collar, so that the jaw members can move apart transversely and/or their upper ends in contact with the clamped members can rock apart on the shoulder to release them upon conclusion of the fastening operation. The jaw members are retained on the anvil as the punch withdraws by an annular ridge cooperating with an annular groove or by two radial pins. The longitudinal position of the anvil member may be adjusted to correspond with the punch stroke by means of a screw-threaded member in a correspondingly internally screw-threaded counter-bore.
