Abstract
An apparatus for fabricating holes in a thin film has an elongated holding block for holding a column of electromagnetic driving coils. The holding block acts as a single unit, and is magnetically attached to a punch diebar. The magnetic attraction between the holding block and diebar provides easy assembly and disassembly of the parts.
Claims6
An apparatus for fabricating holes in a circuit board member, comprising at least one hole fabricating punch including an electromagnetic die head comprising a magnetic coiled solenoid that holds said hole fabricating punch, a holding bar having means defining at least one first aperture disposed therein for receiving said electromagnetic die head, and means defining at least one second aperture containing magnetic means for magnetically attracting and attaching a diebar to said holding bar, said at least one first aperature being positioned above said diebar a given height.
An apparatus for fabrication holes in a sheet member, comprising a plurality of hole fabricating tools, a holding bar having means defining a first row of apertures disposed therein for receiving said plurality of hole fabricating punches, and means defining at least one second row of apertures containing magnetic means for magnetically attracting and attaching a diebar to said holding bar, said plurality of hole fabricating punches being disposed in said first row of apertures and located a given distance above said diebar.
An apparatus for fabricating holes in a sheet member, comprising a plurality of hole fabricating punches, an elongated holding bar having means defining a row of first apertures disposed therein for receiving said plurality of hole fabricating punches, and means defining a pair of rows of second apertures each containing a permanent magnetic for magnetically attracting and attaching a diebar to said holding bar, said plurality of hole fabricating punches being disposed in said first row of apertures and located a given distance above said diebar.
