Abstract: A magnetic device (100) for lifting and/or holding ferromagnetic work-pieces comprises a ferromagnetic housing block (10) and a switchable magnet arrangement accommodated within a cavity of the housing block (10). The housing (10) is formed to define two longitudinal sides that are substantially decoupled magnetically from one another. The switchable magnet arrangement comprises a series of interleaved dipolar magnet units (40, 42) arranged along a longitudinal axis of the housing block (10) between the two sides. The magnet units (40, 42) comprise a series of fixed permanent magnets (40) and rotatable permanent magnets (42) that are cylindrical, or more particularly annular in shape, and traversed by an actuation shaft (24) that rotates the rotatable magnets (42) with respect to the fixed magnets (40) about the longitudinal axis of the housing block (10). The magnet units (40, 42) can thus be switched between an ‘off’ position in which respective magnetic fields are opposed and substantially cancel each other, and an ‘on’ position in which respective magnetic fields are aligned and substantially reinforce each other.
Abstract translation: 用于提升和/或保持铁磁性工件的磁性装置（100）包括容纳在壳体块（10）的空腔内的铁磁壳体块（10）和可切换磁体装置。 壳体（10）形成为限定两个彼此基本上磁耦合的纵向侧面。 可切换磁体装置包括沿着两侧之间的壳体块（10）的纵向轴线布置的一系列交错偶极磁体单元（40,42）。 磁体单元（40,42）包括一系列固定永磁体（40）和可旋转的永久磁体（42），它们是圆柱形的，或更特别是环形的，并且由致动轴（24）穿过，所述致动轴使旋转的磁体 （42）围绕所述壳体块（10）的纵向轴线相对于所述固定磁体（40）。 因此，磁体单元（40,42）可以在彼此相对的磁场相对的“关闭”位置和彼此基本抵消的“开”位置之间切换，并且其中相应磁场对准并且基本上彼此加强的“开”位置。
