SELF-ANCHORING MAGNETIC APPARATUS AND CONTROL UNIT FOR CONTROLLING SAID MAGNETIC APPARATUS'

摘要

The present invention concerns a magnetic apparatus (10A, 10B, 10C, 10D, 10E, 10F) for magnetic clamping of ferrous elements (P1), comprising a support structure (11, 11A) with a plurality of pole pieces (30A) held within its thickness (S), first and second sides (12, 13) being formed in said support structure (11, 11A) at the opposed larger surfaces, the pole pieces of said plurality of pole pieces (30A) comprising at leas.t one first pole piece collector (50), a lateral portion (50A) of each first pole piece collector (50) forming a portion of said first side (12), said pole pieces (30A) generating at least one first magnetic flux (F1) on said first side (12), for magnetically clamping first ferrous elements (P1). The magnetic apparatus (10A; 10B, 10C, 10D, 10E, 10F) is characterized in that, in at least one operating state of said magnetic apparatus, said at least one first magnetic flux (F1) defines a second magnetic clamping surface at said second side (13) for magnetically clamping second ferrous elements (P2), said at least one first magnetic flux (F1) coming out of said second side (13) and reclosing into an adjacent pole piece (30A) with a predetermined field depth (T).
