Embodiment Construction

[0017] figure 1 A typical extrusion line is shown, as it is used today for extruding profiles, whether for producing window profiles or pipes. It shows an extruder 1 in which plastic is melted and fed continuously for molding into an extrusion die 2 . This is followed by a sizing and cooling station 3, depending on the profile, other cooling stations can be used. A puller 4 follows the cooling station. In order to cut the continuous profile 6 to the desired length, a cutting device 5 is then provided.

[0018] figure 2 shows a schematic diagram of the segmentation device according to the invention and corresponds to the figure 1 Position 5 of the view in . Arranged around the extrusion axis 9 is a sleeve 14 with a straight guide 22 , which is in operative connection with a ring element 29 . Separating tools 7 are arranged on the receiving disk 15 and are adjusted via toothed racks 11 and 12 .

[0019] The ring element 29 is thus moved axially along the extrusion axis 9...

Abstract

The invention relates to a device for cutting a preferably thick-walled, extruded pipe (6) to length, said device having at least one cutting tool (7) and a receiving unit (8) for the cutting tool (7). The cutting tool (7) is radially movable in relation to the extrusion axis (9) and is rotatable via further means about the pipe (6) to be cut to length, in order to cut the pipe to length. According to the invention, the receiving unit is connected by means of a receiving disc (15) to a sleeve (14) via a ring element (29), wherein linear guiding elements (22) are arranged on said sleeve (14) parallel to the extrusion axis (9), and wherein at least four linear guiding elements (22) are evenly distributed around the circumference of the sleeve (14).

Description

technical field [0001] The invention relates to a device for cutting extruded tubes to length, preferably thick-walled, said device comprising at least one dividing tool and a receiving unit for the dividing tool, wherein the dividing tool can be positioned relative to The extrusion axis moves radially and can be rotated about the tube to be cut to length via other mechanisms in order to cut the tube to length. Background technique [0002] For cutting extruded tubes to length a so-called flying saw is usually used, in which a circular saw blade is guided from below (bottom saw), from above (submerged saw) or from the side (cross saw) towards the tube to be sawed, Dive into the cross-section of the tube and cut the wall thickness in the first step. Guide the saw blade around the pipe in the second step to cut the pipe completely to length. Here, the tube to be cut to length is clamped during the sawing process; the saw slide or saw slide is then moved at extrusion speed sy...
