MAGNETIC IMPACT ENGRAVING HEAD Russian patent published in 2016 - IPC B44B3/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and is intended for solid flat surface processing, mostly during painting or decorative works. Magnetic impact engraving head comprises body, core with engraving needle, electromagnetic coil, permanent magnet, alternating current source, wherein electromagnetic coil is wound on magnetic conductor, which is equipped with poles, in gap between poles of magnetic conductor is core from non-magnetic composite material, along which permanent magnets are located, wherein poles of constant magnets are oriented so that if one of two magnetic poles of any permanent magnet in row is directed into certain direction, then homonymous magnetic pole of following next in row permanent magnet is directed to opposite side, core with engraving needle is attached to housing of engraving head using mechanical resonator and load-carrying rod, wherein core makes reciprocal movements at interaction of alternating magnetic fields formed around poles of magnetic conductor with alternating current flows through winding coil and magnetic fields of permanent magnets.

EFFECT: technical result is faster operation of engraving head.
