摘要:
A spin forming process and apparatus is disclosed. A workpiece (e.g. sheet metal) is rotated with respect to a forming roller which bears against one of the outer and inner surfaces of the workpiece to deform the workpiece towards a required shape. First and second support rollers bears against the opposite surface of the workpiece. Computer control of the positions of the forming roller and the first and second support rollers allow non-axisymmetric shapes to be manufactured by spin-forming.

The present invention relates to a spinning apparatus for forming a workpiece when the workpiece is arranged in a substantially vertical orientation. The spinning apparatus includes at least one tool capable of altering the shape of the workpiece while spinning. The apparatus also includes a clamp configured to hold the workpiece as the tool works the workpiece. The spinning apparatus includes a spinning arrangement allowing for the vertical arrangement of the workpiece while the tool is working on the workpiece.

A closing machine (1) for closing a work piece (9) by pressing a rotating die (4) against the rotating work piece (9) comprises a die support shaft (41) that supports the die (4), which is disposed coaxially with the work piece (9), rotatably, a power transmission mechanism (401) which transmits the torque of a motor 46 to the die support shaft (41) and a one-way clutch (410) which blocks torque that is input into the power transmission mechanism (401) from the die support shaft (41). During a closing operation, the die (4) is pressed against the work piece (9) so as to contact the work piece (9) slidingly such that the die (4) rotates in accordance with the work piece (9), which rotates at a higher speed than the die (4).

摘要:
The present invention is directed to a method of manufacturing a three piece aluminum wheel assembly comprising the steps of providing a pair of circular blanks made of a heat treatable alloy to be formed into preforms of a general shape. The preforms are subjected to a quenching step in an unconstrained condition to allow for natural thermal deformation during the quenching operation. The as quenched preforms are then subjected to a first forming operation using spin forming to remove the effects of the thermal deformation in the preform, followed by a second forming step using spin forming to shape the component to its desired final shape. The components are then exposed to precipitation heating and finishing to yield the final product.
