Abstract

PURPOSE: To make possible the even and sure staking of laminate pieces to themselves by disposing a fluid cylinder for supporting the laminated iron core cradle in the dies as well as the circuit and check valve which maintain the above-mentioned fluid pressure at the specified pressure as specified then pressing the laminate under even pressure.
CONSTITUTION: In the device of blanking laminated iron core pieces 7 from a strip 6 provided with protrusions in the specified positions, subsequently feeding the same into dies and staking the laminated iron core pieces to themselves by the pressure of a punch 5, a fluid pressure cylinder 9 which supports the cradle 8 of the laminated iron cores 7 is provided and the circuits consisting of a check valve which makes possible the flow from the lower port 9b of the cylinder 9 toward the upper port 9a and prevents its reverse flow and which is not illustrated, the specified fluid circuit which maintains the fluid pressure at the specified pressure and the relief valve which actuates on the specified pressure are disposed so that the laminates 7 are staked always under even pressure by the pressure of the punch 5 and the above-mentioned receiving pressure and the high-quality laminated iron core is thus obtained.
