ABSTRACT:
An apparatus in the form of a die assembly for building a laminated core comprising a plurality of core sheets laminated one above another. Each of the core sheets has a plurality of caulking projections formed therein in the equally spaced relation which serve to achieve caulking between the adjacent core sheets. Prior to punching operation the blanking die is turned by a predetermined angle which is determined by a combination of gear ratio of the gearing mechanism and that of the indexing mechanism. A sprocket on the blanking die is operatively connected to a sprocket on the output shaft of the gearing mechanism and a sprocket on the input shaft of the gearing mechanism is operatively connected to a sprocket on the output shaft of the indexing mechanism. The latter includes a roller gear cam adapted to rotate at a constant rotational speed and a roller gear with a plurality of cam followers arranged in the equally relation around the roller cam so that rotation of the roller gear cam is intermittently transmitted to the roller gear. The input shaft on the roller cam gear is operatively connected to the crankshaft on press machine via endless timing belt so that rotation of the crankshaft is transmitted to the roller gear cam in the one to one relation.
