Forming Machine, in Particular a Forging Hammer

A forming machine, in particular a forging hammer, for forming workpieces, said forming machine comprising:

• an electromagnetic linear motor designed for driving a die, in particular hammer heads;
• wherein the linear motor comprises multiple coil units, which are arranged one behind another along a movement axis (L) of a linear mover, define a mover space and comprise in each case a predetermined coil pole pitch (S) in the direction of the movement axis (L);
• wherein the linear mover includes, in an alternating arrangement along the longitudinal axis (L) thereof:
• first permanent magnets which are magnetized transversely to the longitudinal axis (L) with a predetermined first magnetic pitch (T1), and
• second permanent magnets which are magnetized in the direction of the longitudinal axis (L) with a predetermined second magnetic pitch (T2);
• wherein a ratio of coil pole pitch (S) to first magnetic pitch (T1) is 3:1, and wherein a ratio of first magnetic pitch (T1) to second magnetic pitch (T2) is 2:1.

The forming machine in the form of a forging hammer, the forging hammer comprising:

• the electric linear motor;
• and
• the linear mover, wherein the linear mover includes along the longitudinal axis (L) thereof:
• first permanent magnets with a predetermined first magnetic pitch (T1) and preferably a magnetization which extends transversely relative to the longitudinal axis (L), and
• in an alternating arrangement with the first permanent magnets additionally second permanent magnets with a predetermined second magnetic pitch (T2) and preferably magnetization which extends parallel to the longitudinal axis
• wherein:
• the first and second permanent magnets are realized as ring magnets, and are fixed, in particular clamped, on a piston rod which reaches through the ring magnets:
• a hammer head, to which a forming tool is attached, is fastened on an axial end of the piston rod of the linear mover.
