The pressure in the tube (30) is adjusted bending by bending for the plural bending processes.
The aim of the invention is to provide a device and a method for bending pipes with which the pipe can be bent in different bending directions.
The bending tool (4) comprises adapters (25, 26), in which the bending punch (5) or the bending die (6) is retained in a positioned manner.
A bending processing system is provided with: a first bending processing device; a second bending processing device; and a control means.
The bending die is turned on its axis to perform the bending.
The bend die assembly includes a base (120) and a bend die (32).
The gauge section (2) has a bend-angle gauge and a bend-plane level.
Each bend head has at least one pair of opposing bend and clamp dies defining a die cavity.
The optical fiber has a bending diameter (R) which is not smaller than the bending limit diameter (Re).
If required the material is forwarded through the bending head to a heating unit (114) and retracted to the bending unit to aid in bending.
After one bending process is finished, the pressure in the tube (30), which pressure is adjusted to a pressure suitable for the one bending process, is adjusted from the pressure to a pressure suitable for the next bending.
