摘要：

The paper presents the numerical and experimental results of a new method for producing flanges on hollow parts. With this new method, the flange is extruded by a movable sleeve. This innovative technique is modelled numerically by the finite element method. The effect of workpiece and finished product geometries on the forming process is investigated and failure modes are identfied. The numerical reults are then verified in experiments. The tests are conducted using a three-slide forging press equipped with a special device. The numerical and experimental results show a good agreement, which proves that the developed method is correct.
