Abstract

A pressure pin of a press, in particular a forming press, for transferring a force to a tool component of the press includes a pin body, a sensor element arranged in the pin body for measuring a force which can be transferred via the pressure pin, and an actuator unit arranged in the pin body which has a functional body made of an adaptive material. The adaptive material is designed such that the rheological properties thereof and/or the length thereof and/or the volume thereof can be selectively modified as a function of an electrical and/or magnetic field.
