Workpiece produced from an elongated blank or intermediate product and method for the production thereof

摘要

A method for producing a workpiece from an elongated blank or intermediate product. The workpiece geometry is formed in a first method step, for example by forging the blank or intermediate product, a centering region for subsequent machining of the workpiece between centers being introduced in two oppositely situated sides of the workpiece with reference to the longitudinal axis thereof, and at least one of the centering regions having a desired deformation face. The workpiece is calibrated in a second method step, the desired deformation face being adapted in such a manner that the distance between the contact faces of the centering regions for the machining between centers being adjusted to a predetermined desired measurement. The invention also includes a corresponding workpiece with centering regions, at least one of which has at least one desired deformation face.

1. A method for producing a workpiece from an elongated blank or intermediate product, said method comprising the following steps:
forming a workpiece geometry, wherein a centering region for a subsequent machining of the workpiece between centers is introduced in each of two oppositely situated sides of the workpiece with reference to a longitudinal axis thereof, and wherein at least one of the centering regions has a desired deformation face, and calibrating the workpiece by forging only the desired deformation face to reduce a distance between contact faces of the centering regions for the machining between centers to a predetermined desired measurement.
