Abstract
A method and a plant for the production of a rim for a wheel of a vehicle. At first and by means of an additive manufacturing process, a temporary rim is manufactured, which is provided with a central hub, with a raw ring arranged around the central hub and with a series of spokes, which are radially arranged and connect the raw ring to the central hub; subsequently, the temporary rim is subjected to a flow-forming process, which deforms the raw ring determining an axial lengthening thereof, which transforms the raw ring into a channel having the desired final shape.
Claims6
A method for the production of a rim for a wheel of a vehicle comprising:
- additively manufacturing a temporary rim provided with a central hub, with a raw ring arranged around the central hub and with a series of spokes radially arranged to connect the raw ring to the central hub, wherein the raw ring is a temporary shape and the central hub and the series of spokes are in a final shape;
- and
- subjecting the temporary rim to a flow-forming process, which deforms only the raw ring, which transforms the raw ring from the temporary shape into a channel having a desired final shape, wherein the desired final shape of the raw ring is axially lengthened and thinned relative to the temporary shape of the raw ring, wherein dimensions of the central hub and the series of spokes remain unchanged during the flow-forming process, wherein each one in the series of spokes has at least one lattice structure arranged in an intermediate area between the central hub and the raw ring, and wherein each lattice structure is on an inside and is covered by a continuous skin.
