A die for deforming a workpiece material in a joining tool comprises a head with a top side partially defining a cavity in which the workpiece material is to be deformed, a bottom side opposite the top side, a lateral side arranged between the top side and the bottom side, and a stem which extends along a longitudinal axis from the bottom side of the head. The die further comprises an identification tag, preferably an RFID tag, having an antenna for receiving and/or transmitting a signal, and a storing element for storing information, and the antenna is wrapped circumferentially around the head, such that the antenna entirely surrounds the head. The head may also include a groove extending around the head on the lateral side with the antenna arranged in the groove. Additionally, the die may include a recess with the storing element located in the recess.

Die for deforming material in a joining tool, joining tool and method for identifying and/or detecting the condition of a die

Die for deforming material in a joining tool, joining tool and method for identifying and/or decetcting the condition of a die

A method and apparatus in which a workpiece is supported on one arm of a C-shaped counterforce structure and is operated upon by a mechanism supported on the other arm of the counterforce structure. The operation causes deformation of the counterforce structure, which is measured, and the operation is adjusted responsive to the measured deformation.

Method for riveting or piercing and a device for carrying out the method

The method according to the invention for riveting, or self-piercing, by means of a riveting or self-piercing device (), having a male die () guided by a pick-up device (), both of which in each case can be moved towards a female die () and/or a workpiece (), wherein the female die () and riveting or self-piercing device () will be connected to one another via a counterforce structure (). The relative movement between the pick-up device () and the counterforce structure () is measured by a first sensor (), and the relative movement between counterforce structure () and male die () is measured by a second sensor (). The depth of the riveting or piercing is adjusted with the aid of the two measured values. The associated device allows fast, accurate detection of the thickness of a workpiece () and precise piercing or riveting with constant predetermined depth irrespective of variations in the quality of the material or other parameters, which can result in deformations of the counterforce structure () during the piercing process.
