Abstract
A thin walled body is deformed in a process in which the body is gripped securely in a holding station and, whilst gripped in the holding station, tooling engages to deform the peripheral wall of the body at a predetermined wall zone. The tooling is provided at a tooling station which is adjacent the holding station during deformation. The predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station.
Claims13
A method of deforming a thin walled body comprising:
- (i) holding the body gripped securely in a holding station;
- and
- (ii) whilst gripped in the holding station engaging tooling to deform the peripheral wall of the body at a predetermined wall zone, the tooling comprising internal and external tooling and being provided at a tooling station which is adjacent the holding station during deformation;
- wherein the predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station and wherein the tooling station is provided with a cam formation arranged such that relative movement of the tooling with respect to the cam formation in the axial direction of the body causes the tooling to move to engage the peripheral wall of the body.

Apparatus for deforming a thin walled body comprising:
- i) a holding station for holding the body gripped securely;
- ii) a tooling station including tooling comprising internal and external tooling arranged to engage with and to deform the body at a predetermined wall zone on the peripheral wall whilst the body is gripped securely in the holding station, the tooling station being positioned at a location adjacent the holding station and advanced relative to the tooling station for deformation of the body;
- iii) a cam formation provided at the tooling station arranged to urge the tooling to move to engage the peripheral wall of the body upon relative movement of the tooling with respect to the cam formation in the axial direction of the body;
- iv) determination means for determining the orientation of the cylindrical body relative to a reference datum situation;
- and
- v) means for co-ordinated movement to reconfigure the body about an axis of the body to accord with the datum situation prior to the body being gripped at the holding station in a fixed orientation for deforming of the wall of the body.
