Tube expanding machine EXPAN series

Machines for small and medium-sized batches to produce metal bellows from tubes for compensators. Machine series “EXPAN“ Forming of individual corrugations by means of a mechanical expanding technique Sensors to identify bellows edges, motor-controlled re-adjustment of the mounting table height Integrated swivel motion of the basic die to avoid pressure marks Stable welded steel construction for installation in the machine pit (platform also alternatively possible) Profiling of individual corrugations by follow-up profiling on the profiling machine of the PRM type Rapid and easy die change Basic dies can be adapted in a customized manner to the diameter range required; within this range, the easy exchange of forming segments offers great flexibility. Diameter - 100– 500 mm - 350 – 1600 mm - 1400 – 3000 mm Wall thickness - 1×0,3 – 5×1,0 mm - 1×0,5 – 6×1,0 mm - 1×1,0 – 6×1,0 mm Cycle time / corrugation - ca. 30 – 45 s - ca. 30 – 45 s - ca. 45 – 90 s
