Screw-type extrusion machine having tie rods loaded by a pre-stressed spring system |
摘要 |
In a screw-type extrusion machine comprising a composite casing which comprises casing sections fitted together in a longitudinal direction, the casing sections being tightly tautened relative to each other by a plurality of tie rods which extend parallel to each other in the longitudinal direction of the casing on the outside thereof, it is provided with a view to avoiding any over-stressing of the tie rods in the hot condition and to avoiding any leakage between the casing sections in the case of low temperatures and non-uniform temperature distribution, that the tie rods are loaded in the longitudinal direction by a pre-stressed spring system.
