Abstract
PURPOSE: To disperse the deviation of thickness of sheet, and to laminate the sheet into straight form, by piercing the specified number of grooves longitudinally in the outer circumference of the iron core placing an interval, and by lining up the iron core sheet taking the grooves as the reference at laminating work.
CONSTITUTION: A groove for every one iron core sheet is pierced in the longitudinal direction of the iron core material in the outer circumference of the iron core; the number of grooves is determined as a number divisible by the least common multiple of numbers of the clamp grooves or the weld grooves, and the grooves are located placing an interval uniformly from one to another. That is, if the iron core material is sent in, the shaft 10 rotates as the rotational speed equal to that of the crank shaft of the press, and the Maltese cam 10f turns the Geneva gear 7f. When the press slide goes down to the blanking position, the cam 8a of the cam shaft 8 pushes up the backing plate 6a, and the grooving punch 2a pierces the groove. Next, when the crank shaft makes one turn and the press slide goes up and down, the shaft 10 and the Maltese cam 10f also make one turn, the cam shaft 7 and the Geneva gear 7f make a quarter turn, and only the grooving punch 2b, being pushed up by the cam 7b, pierces the groove.
