The present invention relates to a magnetic apparatus for clamping ferromagnetic workpieces, comprising a first magnetic clamping plate with a first magnetic circuit therein for generating a first magnetic flux when said first magnetic circuit is on, to define a magnetically active portion of said first magnetic plate, acting as a magnetic clamping surface. The present invention is characterized in that the apparatus further comprises a spacer extending in a predetermined direction of extension (Y-Y), a second magnetic clamping plate with a second magnetic circuit therein for generating a second magnetic flux when said second magnetic circuit is on, to define a magnetically active portion of said second magnetic plate, acting as a magnetic clamping surface, said spacer being interposed between said first magnetic plate and said second magnetic plate, said spacer, said first magnetic plate and said second magnetic plate being rigidly and integrally connected together, wherein the first magnetic flux generated by said first circuit is higher than the second magnetic flux generated by said second magnetic circuit, with the clamping surfaces defined in said first magnetic plate and said second magnetic plate (4) having the same area.

Abstract
The present invention relates to a magnetic apparatus for clamping ferromagnetic workpieces, comprising a first magnetic clamping plate with a first magnetic circuit therein for generating a first magnetic flux when said first magnetic circuit is on, to define a magnetically active portion of said first magnetic plate, acting as a magnetic clamping surface. The present invention is characterized in that the apparatus further comprises a spacer extending in a predetermined direction of extension (Y-Y), a second magnetic clamping plate with a second magnetic circuit therein for generating a second magnetic flux when said second magnetic circuit is on, to define a magnetically active portion of said second magnetic plate, acting as a magnetic clamping surface, said spacer being interposed between said first magnetic plate and said second magnetic plate, said spacer, said first magnetic plate and said second magnetic plate being rigidly and integrally connected together, wherein the first magnetic flux generated by said first circuit is higher than the second magnetic flux generated by said second magnetic circuit, with the clamping surfaces defined in said first magnetic plate and said second magnetic plate (4) having the same area.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
