Device and method for cutting an extruded pipe to length

A device for an extrusion line, the device for cutting an extruded plastic pipe to length, the device comprising a separating unit that comprises:

• a rotating receiver that is configured to be rotated about an extrusion axis of the extruded pipe, the rotating receiver being rotatably mounted in the separating unit;
• a first linear electromechanical drive arranged on a first surface of the rotating receiver;
• a first carrier operatively coupled to the linear electromechanical drive and moveably arranged on the first surface of the rotating receiver;
• a tool comprising a roller combination or a chamfering tool operatively coupled to the first carrier using a spring element, the tool being configured to smooth a bead that is formed during chipless separation, prevent sagging, or chamfer a profile of the extruded pipe;
• a second linear electromechanical drive arranged on the first surface of the rotating receiver;
• a second carrier operatively coupled to the second linear electromechanical drive and moveably arranged on the first surface of the rotating receiver;
• and
• a cutting tool comprising a cutting blade operatively coupled to the second carrier,
• wherein the first linear electromechanical drive is configured to controllably move the first carrier in order to move the tool towards and away from the extrusion axis in a manner perpendicular to the extrusion axis,
• wherein the spring element is configured to develop a spring action that is configured to yield to a force counter to a separating force by sliding resiliently away from an occurring load, away from an extrusion axis, radially with respect to the extrusion axis, wherein the separating force occurs between the tool and the extruded plastic pipe during the cutting, upon the force counter to the separating force being greater than a required separating force for cutting the extruded pipe, and
• wherein the second linear electromechanical drive is configured to controllably move the second carrier in order to move the rotating cutting blade towards and away from the extrusion axis in the manner perpendicular to the extrusion axis.
