Abstract
The basic invention relates, in particular, to a forging hammer, comprising an electric linear drive, having a linear rotor and a ram that is coupled to the latter for the purpose of executing forging motions, wherein the linear rotor and the ram are connected to each other through an interposed flexurally elastic decoupling structure that acts between the linear rotor and the ram, and the decoupling structure is realized and arranged to decouple the linear rotor, at least partly, from relative motions of the ram relative to the linear rotor that occur during a forging motion.

A forging hammer, comprising:
- an electric linear drive, having a linear rotor and a ram that is coupled to the latter for the purpose of executing forging motions;
- wherein:
- the linear rotor and the ram are connected to each other through an interposed decoupling structure that acts between the linear rotor and the ram;
- and
- the decoupling structure is realized and arranged to decouple the linear rotor, at least partly, from relative motions of the ram relative to the linear rotor that occur during a forging motion.
A forging hammer, comprising:
- an electric drive having a linear rotor, wherein:
- the linear rotor comprises a magnetic portion, extending in the axial direction, that is composed of a plurality of permanent magnets disposed in succession in the axial direction, wherein, preferably, the permanent magnets are realized as magnetic annular disks, and are fixed, in particular clamped, preferably by fastening elements placed on both sides of the magnetic portion, on a piston rod that goes through the magnetic annular disk;
