Title: Mfg.  rotationally symmetric titanium@ alloy components shaped as tubes pots or cones - comprises cold forming by means of press roll sets
IPC: B21D22/14
Filed: 1992-05-01
Abstract: The method concerns manufacture of a rotationally symmetric tube, pot or cone shaped component made of a titanium alloy. The component is produced from a hollow cylindrical, pot or disc shaped blank (1) by cold forming with the use of a press rolling process involving thinning and axial stretching of the circumferential region (11) of the blank (1). The circumferential region (11) of the blank (1) is thinned and axially stretched by means of several press rolls engaged at the same time. Each roll reduces the original material thickness in the circumferential region (11) of the blank at least by 15%. The rolls are distributed uniformly over the blank circumference and are separated by a small axial distance - which is less than the axial stretch produced by them - from one another. The press rolling process is carried out in a single pass of the rolls moving in unison in the axial direction of the blank. The total reduction in the wall thickness per pass is at least 50%. The rolls are provided with a leading holding-down shoulder, a press shoulder and a following smoothing shoulder. Annealed titanium alloy Ti6Al4V is used as the blank material. USE/ADVANTAGE - For manufacture of rotationally symmetric titanium alloy components. In comparison with known methods (involving welding operations), it is less labour and time intensive.

These chambers are filled with a damping fluid which can flow from one chamber to the other when there is a sufficient pressure difference to force open one of the valves formed by the leaf springs. USE/ADVANTAGE - Anti-vibration mounting which can damp out vibrations of large amplitude.
