摘要:
The present invention relates to a movable pole extension (4) for a magnetic clamping apparatus (1) for holding a ferromagnetic workpiece (P), comprising a fixed pole member (5) extending in a predetermined longitudinal direction (X-X) and at least two pole members (6, 7) attached to said fixed pole member (5), said at least two pole members (6, 7) being movable relative to said fixed pole member (5). The movable pole extension is characterized in that it has holder means (8) operably coupled to said fixed pole member (5), wherein said holder means (8) are movable in said predetermined longitudinal direction (X-X) between a first operating position (Pl) and a second operating position (P2) and operate on said at least two movable pole members (6, 7) to hold them in coupled contact with said fixed pole member (5).

A magnetic holding apparatus comprising a base plate (1), lateral walls (5), a plurality of pole pieces (4) disposed in parallel rows to define a work-holding surface (8) and magnetizable and demagnetizable magnet core members (3) between the pole pieces (4) and the base plate (1); the pole pieces (4) are spaced apart by a gap equal to or less than half the axial length of the magnetic core members (3) which are encircled by magnetizing and demagnetizing electric coils (6).
摘要:
The present invention concerns a monolithic and self-anchoring magnetic apparatus (10A, 10B, 10C, 10D, 10E, 10F) for magnetic clamping of ferrous elements (P1, P2), comprising a support structure (11, 11A) having predetermined width (L), length (1) and thickness (S) with a plurality of pole pieces (30A), first and second sides (12, 13) being formed in said support structure (11, 11A) at the larger opposite surfaces, said plurality of pole pieces (30A) comprising at least one first pole piece collector (50) and generating in said first side (12) at least first magnetic flux (F1) so as to define a first magnetic clamping surface for magnetically clamping first ferrous elements (P1). Characteristic of the monolithic and self-anchoring magnetic apparatus is that plurality of pole pieces (30A) are held within the thickness (S) of said support structure (11, 11A), a lateral portion (50A) of each first pole piece collector (50) forming a portion of said first side (12) and each first pole piece collector (50) is formed of one piece with said support structure (11) to create a monolithic magnetic apparatus (10A), the plurality of pole pieces (30A) comprise a second pole piece collector (60), a lateral portion (60A) of said second pole piece collector (60) forming a portion of said second side (13) so as 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).
摘要:
The present invention relates to magnetic anchorage equipment (1) comprising a frame (2) able to contain a plurality of polar units, each of the plurality of polar units having a ferromagnetic polar element which identifies an anchorage surface (3) and a self-testing unit (4) for checking the magnetic equipment (1). The magnetic anchorage equipment (1) is characterized in that the self-testing unit (4) for checking the magnetic equipment (1) is at least partly integrated in the frame (2).
