Abstract

PURPOSE:To heighten productivity employing a progressive working by changing the position of a stocker according to the position of a die used with selective use of several dies provided for punching keyways. CONSTITUTION:While a core material is being delivered sequentially in the direction of the arrow, a shaft hole 4 and a slip 5 are punched therethrough in the first process, a keyway 1a punched in the second process. Then, the material is cut up properly in the third process. Here, a plurality of dies for punching keyways 1a are so arranged on a concentric circle at a pace of 45 deg., for example, that the dies used are changed each time a proper number of cores are punched. The stocker of the cores is turned according to the position of the die used to align the position of the keyways thereon. This enables the employment of a progressive working regardless of variations in the thickness of the core material.
