摘要： A device produces plastic pipes by extrusion, involving an extruder, a pipe head connecting to the extruder in production direction, having a base material, mandrel, and sheath. A melt channel, formed between the mandrel and sheath in production direction, promotes flow at least at the mandrel and sheath end, the mandrel and sheath being adjustable forwards and backwards relative to one another, and the outer mandrel surface and/or the inner sheath surface at least partially having a material with greater sliding capacity than the base material. Mandrel diameter at the end conically widens or narrows, and/or the mandrel end is curved so the diameter widens, narrows, or remains constant, and the inner sheath diameter at the end conically widens, narrows, or remains constant, and/or the sheath end is curved so the diameter widens or narrows, or two further surface sections, parallel and cylindrical, extend at the mandrel and sheath end.

摘要： A calibration and cooling tank of an extrusion line, which connects to an extrusion tool, wherein a vacuum can be applied to the calibration and cooling tank for calibrating the plastic melt emerging from the extrusion tool, wherein the calibration and cooling tank extends along an extrusion axis. The calibration and cooling tank is modularly structured, wherein at least one module forms a calibration and cooling section and the module has a connection region on both sides to which an additional module can be attached. The connection region includes a flange that extends from the base element of the calibration and cooling tank to the outside.

摘要： A method cuts an extruded pipe to length using a separating device. The separating device includes a separator rotating about an extrusion axis of the extruded pipe, the separator being rotatably mounted in the separating device, and cutting tools being arranged on the separator. The cutting tools are configured to carry out the separation. The method includes transferring energy to move the cutting tools. The energy is transferred from a stationary outer region of the separating device to a movable inner region of the separating device. The energy is transferred continuously or cyclically and the transferred energy is buffered in an energy storage device. The energy is transferred inductively or capacitively. A discharge time of the energy storage device is between 2% and 25% of a total separation cycle.

摘要： In an embodiment, the present invention provides a method for increasing the cooling performance of an extrusion line and for extruding a plastics profile, in particular a plastics tube, in an energy efficient manner, the method including the steps of: melting plastics material in an extruder; shaping a plastics strand and feeding the plastics strand to a die; shaping a plastics profile using the die; and calibrating and curing by cooling the profile in a cooling and/or calibration device, a gaseous medium being drawn through one or more cooling tanks in order to cool the outside of the profile. A temperature and a saturation of the gaseous medium is increased between an inlet region and an outlet region for the gaseous medium. A liquid medium is added between the inlet region and the outlet region using spray nozzles.
