An interchangeable die comprises a die head, on which a die feature is formed, and a die shank extending in an axial direction from the die head. The die shank includes a first axial shank section, which is adjacent to the die head, and a second axial shank section, which is arranged on the opposite axial side of the first axial shank section from the die head. The first axial shank section has a first diameter and the second axial shank section has a second diameter smaller than the first diameter. The die shank is introducible into a shank receptacle of a die receiving section of a joining tool. A fastening contour for fastening the interchangeable die to the joining tool is formed on the interchangeable die. The fastening contour is configured such that a plug-and-turn connection is establishable between the interchangeable die and the joining tool.

A die for use with a cold-formed joint tool such as a clinching tool or clinch punch or self-piercing rivet punch. A split die made of a plurality of partial cup-shaped segments is disposed within a collar that defines a recess. The recess includes a forming area in which the cold-formed joint is formed and a relieved area in which the partial cup-shaped segments are shifted radially outwardly after forming to permit removal of the cold-formed joint tool from the cold-formed joint.

A system and method for rivet setting comprising an anvil having an anvil face and a plunger having a sensor coupled to a control system that measures the distance between the anvil face and the work surface during the rivet setting process and stops the rivet driver when the driven rivet head achieves a desired head height above the work surface. In preferred embodiments, the control system also communicates the stage of the rivet driving cycle to the operators to expedite the rivet driving process.

The invention relates to a method of attaching a functional element to a sheet metal part. The functional element has a head part having a ring-shaped support surface and a tubular rivet section that is designed as self-piercing and that extends at the side of the support surface of the head part and away from said head part.

Provided is a riveting device that deforms a rivet inserted into a through-hole formed in a plurality of plate-shaped members disposed in a superimposed state and secures the plurality of plate-shaped members, the riveting device including: an upper anvil that is disposed in a state in which the upper anvil faces an end surface of a head of the rivet; a lower anvil that is disposed in a state in which the lower anvil faces an end surface of a shaft portion 210 of the rivet; and a pressurizing mechanism that generates a pressurizing force of causing a distance between the upper anvil and the lower anvil along an axial line to decrease and plastically deforms the rivet, in which the pressurizing surface of the lower anvil is formed into a flat shape that perpendicularly intersects the axial line, and a surface roughening treatment is performed on the pressurizing surface.

Provided is a swaging device including: an upper anvil that is disposed in a state in which the upper anvil faces an end surface of a head of a rivet; a lower anvil that is disposed in a state in which the lower anvil faces an end surface of a shaft portion of the rivet; and a pressurizing mechanism that generates a pressurizing force of causing a distance between the upper anvil and the lower anvil along an axial line to decrease and plastically deforms the rivet, in which an end surface of the upper anvil includes a bottom surface that perpendicularly intersects the axial line X and a support surface that has a projecting length in a direction of the axial line with respect to the bottom surface gradually increasing from an inner circumferential side toward an outer circumferential side in the radial direction formed therein, and an inclination angle of the support surface is smaller than an inclination angle of the inclined surface of the rivet by a predetermined angle.

An end effector may be configured to be modular in nature such that the weight of the end effector may be adjusted for specific applications. The end effector may further be configured to accept interchangeable dollies, wherein a dolly may be configured with a jacket on a contact end of the dolly, which contact end is configured to engage a distal end of a rivet during use.
