Abstract

The drawing shows in section an improved press for ferrite cores. A circular table 2 is rotated about a central vertical stationary shaft 3. Table 2 carries twelve peripherally arranged core forming units 4. Units 4 are commercially available and each includes eight circularly arranged die cavities, not shown, formed in its upper surface 5. Within each die cavity is positioned a stationary die rod which forms the core aperture, and a punch which is lowered for filling the die cavity, raised for pressing a core and for ejecting a pressed core. As table 2 turns, a rod 7 rides on a stationary circular cam track 6 to raise the punch at a pressing station and an ejection station, and to lower the punch at a station for filling the die with ferrite powder.

Rotary Core Press

The drawing shows in section an improved press for ferrite cores. A circular table 2 is rotated about a central vertical stationary shaft 3. Table 2 carries twelve peripherally arranged core forming units 4. Units 4 are commercially available and each includes eight circularly arranged die cavities, not shown, formed in its upper surface 5. Within each die cavity is positioned a stationary die rod which forms the core aperture, and a punch which is lowered for filling the die cavity, raised for pressing a core and for ejecting a pressed core. As table 2 turns, a rod 7 rides on a stationary circular cam track 6 to raise the punch at a pressing station and an ejection station, and to lower the punch at a station for filling the die with ferrite powder.

Each unit 4 has a slide 8 that is moved radially inward at the fill station and the core ejecting station, to clear the cavity for filling it with ferrite and for ejecting a punched core. At a punch station the slide 8 covers the die for punching. A guide 9 supports slide 8 for radial movement. A cam 10 is fixed to shaft 3 to extend and retract the slide as the table turns. The leftmost unit 4 is shown in the punch position and the rightmost unit 4 is shown in the fill position. Several punch and fill stations are provided.
