Method and apparatus for the manufacture of gearwheels

摘要

In the new method, the stamp (4, 5) acts from both sides on the blank for the gearwheel (2), which is mounted on the dividing apparatus (11). By means of the indexing mechanism (3), the gearwheel is turned by one tooth after each stroke. Hammering is performed in a rapid sequence and the depth of the stroke is increased continuously by means of the adjusting devices (8). The stamps (4, 5) are matched to the shape of the tooth and hammer in the tooth gap, while the displaced material rises and forms the tooth. In particular, there are limit stops on the stamp which ensure that the material does not escape at the side. In this way, it is possible to manufacture high-quality gearwheels without cutting. <IMAGE>
