Abstract (en)
[origin: WO2007018499A1] An apparatus and method are provided for forming a shaped part from a tube (14) having an end and at least one bend, the shaped part having an enlarger portion between the bend and the end. The shaped part is formed by applying pressure fluid within the tube (14) while maintaining pressure on the end of the tube to cause expansion of the tube between the bend and the end. The shaped part is formed on a hydraulic press (10) having upper (18) and lower dies (16). The apparatus (10) includes at least one side assembly (22) pivotally mounted to the lower die (16) with a cylinder (28) for applying pressure to at least one end of the tube (14). The apparatus further includes seals (34) for sealing ends of the tube (14) and a fluid control device (36) for pressurizing the fluid within the tube.
