Claims

[Scope of utility model registration request]

(1) It has a die for punching a laminated core piece from a strip in which cut and raised protrusions with a predetermined protrusion amount are provided at predetermined positions,
For manufacturing a laminated core, the laminated core pieces that are successively drawn into the die are caulked through the cut and raised protrusions using the pressurizing force of a punch when being drawn into the die to obtain a product laminated core. In the progressive mold device, there is provided a cradle for receiving from below the laminated core pieces drawn into the gou and stacked one on top of the other, a fluid pressure cylinder for supporting the cradle, and a fluid pressure cylinder at the bottom of the gou that communicates with the inner space of the gou in the lateral direction. and a product ejecting actuator provided on the opposite side of the passage across the inner space of the gouge and arranged to be able to expand and contract in the direction of the passage. retracting the cylinder to lower the pedestal to a predetermined lower limit position corresponding to the passageway, then extending the actuator to push the product on the pedestal into the passageway, and then retracting the actuator;
and a sequence control device that then extends the cylinder and raises the pedestal.

(2) The sequence control device includes a first sensor that detects that the cradle has been lowered to the lower limit position, and a first sensor that detects that the cradle has lowered to the lower limit position, and a sensor that detects that the cradle has lowered to the lower limit position. a second sensor that detects that the actuator has been raised; a third sensor that detects that the laminated core piece has come into contact with the cradle; a fourth sensor that detects the extension limit position of the actuator; Utility model registration claim No. 1, which includes a fifth sensor that detects the retraction limit position of the actuator, and a sequence control circuit that controls the cylinder and the actuator according to a predetermined procedure according to the signals of the respective sensors. ) The product removal device described in section 2.
