The trance berth for the push belt for the non-stage transmission (intersection) the blanking of the element (driving out) prevention of the Bali formation in processing

摘要

It regards the method in order to form the intersection element which is designed as portion of the push belt for the non-stage transmission. The intersection element has two main substance surfaces and the around surface. The intersection element during blanking operating is driven out from the base material. It accepts between the other parts and the territory (46) the type which it possesses (45) is provided. During blanking operating, when the intersection element accepts and the territory (46) enters, the around surface of the intersection element moves type (45) around bevelling the end (48) paralleling. Type (45) the around end (48) it possesses the chamfer whose part is small at least relatively, the around end (48) the other part has the relatively large chamfer. The around end of former (48) at part, the Bali formation which is in the midst of blanking operating is prevented, can obtain the quality where on the one hand, the latter around end (48) at part, the around surface of the intersection element is high relatively.
