Abstract: The invention relates to a method for the forming of a workpiece, in particular a blank, composed of sheet steel, in which method the following steps are performed in succession: providing a workpiece composed of multiple steel layers which have been non-detachably connected to one another by roll-bonding and of which at least two steel layers have a different strength and/or elongation at fracture, heating the workpiece, and subjecting the workpiece to hot forming. To ensure a high strength and at the same time the easiest possible formability, the invention proposes that at least one section of the hot-formed workpiece is hardened, and that the workpiece is subsequently subjected to cold forming in the region in which the hardening has been performed. The invention also relates to a corresponding workpiece.

Abstract: Exemplary illustrations of a method of making a wheel may include stamping a wheel blank, and forming a lip extending about a periphery of an aperture defined by the wheel blank. The aperture may be configured to receive a valve stem. The method may further include refining the lip about the periphery of the aperture. The lip may define an axial thickness greater than a baseline thickness of the wheel blank adjacent the aperture. In some exemplary approaches, a method further includes providing a second wheel blank having a second aperture configured to receive a valve stem. The second aperture may define an axial thickness greater than the baseline thickness of the first wheel blank, while the lip axial thickness of the first wheel blank is substantially equal to axial thickness of the second aperture

Abstract: A method of forming a wheel disc starts with a flat blank. A plurality of windows are formed in the wheel disc, wherein each window has a respective outer edge proximate with a continuous outer band around a periphery of the wheel disc. The windows define a plurality of spokes between adjacent windows, and the angular size of each of the windows along the outer band is preferably greater than the angular size of each of the spokes. The outer band is partially closed toward a cylindrical shape by engaging a cam die against at least a portion of the outer band. The outer band is substantially fully closed into a cylindrical shape by axially wiping the outer band using a cylindrical die. The intermediate camming operation achieves the desired final shape after wiping without introducing stresses that would weaken or distort the wheel disc.
