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.
Claims20
A forging hammer, comprising:
- an electric linear drive, having a linear rotor with an extension, the extension comprising a piston rod;
- a ram coupled to the linear rotor, wherein the ram is configured to execute forging motions via movement of the linear rotor, wherein execution of the forging motions generates relative motions secondary to the movement of the linear rotor;
- a fastening structure for fastening the ram to the extension of the linear rotor;
- and
- a decoupling structure interposed between the linear rotor and the ram, the decoupling structure comprising a flexurally elastic decoupling element disposed between the extension of the linear rotor and the fastening structure, the decoupling element having a flexural elasticity that is greater than that of the extension and the fastening structure, such that the decoupling element decouples the linear rotor from the relative motions generated by the forging motions of the ram.
A forging hammer, comprising:
- an electric linear drive having a linear rotor, the linear rotor comprising a piston rod;
- and
- a ram coupled to the linear rotor;
- wherein:
- the linear rotor comprises a magnetic portion, extending in an axial direction (L), the magnetic portion comprising a plurality of permanent magnets disposed in succession in the axial direction;
- the permanent magnets are comprised of magnetic annular disks;
- and
- the permanent magnets are fixed by fastening elements placed on opposing sides of the magnetic portion and attached to the piston rod of the linear rotor that passes through the magnetic annular disks.
