| 摘要 |
The invention relates to a retaining device (26), in particular on an extruder (2), for several die plates (27) which can be arranged immediately one after the other in the extrusion direction (6) to form an extrusion die (28) with an inlet region (29) and an outlet region (30). At least two tension elements (37) are provided spaced at a distance apart from one another perpendicular to the extrusion direction (6), which can co-operate with the die plates (27) respectively in the region of opposing first side ends (34) which they span. At least one holding element (40) projects, in an end region (39) of the tension element (37) which may be directed towards the outlet region (30), into the cross-sectional surface bounded by the side ends (34) of the die plates (27) disposed one after the other and engages round these side ends (34). A clamping mechanism (44) is provided between the two spaced apart end regions (39, 42) of the tension elements (37) and/or between the tension elements (37) and the die plates (27) of the extrusion die (28) co-operating therewith. The invention further relates to a shaping system (3) with a retaining device (26) and a method of retaining an extrusion die (28). |
