Abstract

A press for making torroidal ferrite cores comprises machine frame 2, support 4 for die 6 fixedly mounted on frame 2, and upper and lower punches 8 and 10 cooperable to press a ferrite core in die 6. Upper punch 8 is supported by a pair of beams 12-12 whose ends are fixedly supported in frame 2 and which are coupled together between their ends by spacer 14. Punch 8 is mounted on lower beam 12 at the midpoint of such beam. Beams 12-12 flex slightly as upper punch 8 is urged downwards into die 6 during a core pressing operation by cam 16 operating through push rod 18. A second cam 19 retracts punch 8 from die 6 by bell crank lever 20 to permit ejection of the pressed core from the die. Lower punch 10 is supported by a pair of beams 22-22, similar to beams 12-12, coupled together by spacer 24.

Press for Ferrite Cores

A press for making torroidal ferrite cores comprises machine frame 2, support 4 for die 6 fixedly mounted on frame 2, and upper and lower punches 8 and 10 cooperable to press a ferrite core in die 6. Upper punch 8 is supported by a pair of beams 12-12 whose ends are fixedly supported in frame 2 and which are coupled together between their ends by spacer 14. Punch 8 is mounted on lower beam 12 at the midpoint of such beam. Beams 12-12 flex slightly as upper punch 8 is urged downwards into die 6 during a core pressing operation by cam 16 operating through push rod 18. A second cam 19 retracts punch 8 from die 6 by bell crank lever 20 to permit ejection of the pressed core from the die. Lower punch 10 is supported by a pair of beams 22-22, similar to beams 12-12, coupled together by spacer 24. Beams 22-22 flex slightly as lower punch 10 is urged upwards in die 6 by cam 26 acting through push rod 28 to eject a finished core from die 6. Cam 26 also acts through linkage 30 to retract punch 10 downwards to its normal operative position within die 6. When upper Punch 8 is pressing a core in die 6 lower punch 10 forms the bottom of the die cavity. Stop 32 carried by lower beam 22 engages spring-biased annular member 34 mounted on machine frame 2 in the operative position of lower punch 10 to provide a predetermined spring force opposing the force applied by the upper punch 8. Ferrite power is delivered to die 6 by a feed mechanism shown generally a...
