Non-swarf-producing device for making hub, forming projecting nose and recess of appropriate height and depth

摘要

The hub-making device produces the hub (6) on a transmission component consisting of a sheet plate (1) in a pressure process using a tool (3) and at least one pressure roller (4). There is a recess (5) in the surface facing the hub being formed, consisting of a projecting nose. The recess is of a height and depth corresponding to those of the hub being formed.
