Method and apparatus for the production of a cup-shaped product with internal toothing

摘要

To produce a cup-shaped product (w) with internal toothing use is made of a die with a punch (6) having the relevant tooth profile and a counterpunch (5) interacting with the latter. The first-mentioned punch (6) interacts with a flexible device (7) that limits its movement and that ensures that the two punches (6, 5) grip the product (w) to be formed firmly between them at all times. <IMAGE>
