摘要:
The present invention relates to a magnetic apparatus for magnetically anchoring ferrous elements (P1), comprising a support structure (11) in which thickness (S) a plurality "N" of polar units (30A) is housed, said support structure (11) identifies a first and a second side (12, 13) at the opposite surfaces with the greatest extension, each of said plurality "N" of polar units (30A) comprising a coil (30) having a support (31) of predetermined profile and an electric conductive element (32) wound on said support, a first magnetic core (40) with a first coercive value, generating a first magnetic flow oriented in a first magnetic direction, a plurality of second magnetic cores (90A, 90B) having each its own coercive value, different from said first coercive value. A characteristic of the apparatus is that a first part (90A) of the plurality of second magnetic cores (90A, 90B) generates a second magnetic flow oriented in a second magnetic direction and a second part (90B) of the plurality of second magnetic cores (90A, 90B) generates a third magnetic flow oriented in a third magnetic direction, said third magnetic direction being parallel to said first magnetic direction and of different direction with respect to said second magnetic direction.

A magnetic device for gripping and clamping a workpiece in a machining unit or on a machining line comprises a magnetic plate (2) of the type including a distribution of high-energypermanent-magnet modules (3), which can be electrically activated. The device further comprises an auxiliary workpiece-holder plate made of ferromagnetic material, which rests on a main surface of the magnetic plate and has a top surface (10) shaped in a way complementary to a surface of the workpiece (P) that rests thereon. The workpiece (P) rests on the top surface (10) of the auxiliary workpiece-holder plate (8) only in points corresponding to some supporting pads (13), whilst the facing surfaces of the workpiece (P) and auxiliary workpiece-holder plate (8) are kept slightly set apart from one another for most of their extension. Precise referencing in the plane of the main surface (6) of the magnetic plate (2) between the workpiece (P) and the auxiliary workpiece-holder plate (8) is obtained by means of two locating pins (14) projecting from the auxiliary plate (8) and received within respective seats (15) of the workpiece (P). There may be provided a protective shroud (16) above the magnetic plate (2), having an opening (16b) from which the aforesaid auxiliary workpiece-holder plate (8) projects.

摘要:
The present invention relates to an Electro Permanent Magnetic work holding system having additional solenoid(s) positioned within the main pole(s) of the working face. Conventional double magnet EPM work holding systems for ferromagnetic work pieces suffer from unsatisfactory control of flux affecting working operations and incidence of residual magnetism in work pieces. The present invention aims at overcoming these difficulties and provides an Electro Permanent work holding system characterized in that the said system comprises a work holding face (1), a base plate (2), a set of reversible magnets (5), solenoid(s) for controlling reversible magnets (3), main pole(s) (4) positioned above the reversible magnets, a set of non-reversible permanent magnets (6), set of additional solenoid(s) (7) within the main poles of the working surface and magnetic insulator (8). These set of additional solenoids positioned within the main poles of the working facilitates better control of flux for proper holding and also demagnetization of the work piece as and when needled.
