The invention relates to a device for the extrusion of round blanks (1), comprising an extrusion sleeve (2) and a die (3), by means of which the round blanks (1) can be pressed in the extrusion sleeve (2), as well as a feeding device (4, 5, 6) by means of which the round blanks (1) can be transported between the die (3) and the extrusion sleeve (2), wherein the feeding device (4, 5, 6) comprises a guide rail (4) in which the round blanks (1) are arranged one behind the other and at the lower end thereof means (5, 6) are arranged for separating the round blanks (1). The invention is characterized in that the separating means (5, 6) comprise a separating cam (5) that is rotatable about a rotating axis (5a) in a direction of rotation (5b), the outer surface of said separating cam comprising at least one convex region (5c), whose distance to the rotating axis (5a) decreases in the rotating direction (5b) of the cam (5), and at least one concave region (5d), whose curvature radius is adapted to the diameter of the round blanks (1). |
