Method for forming a crowning on a sintered component

A method for forming a crowning on at least one surface of a sintered component made from a sintering powder, the sintered component comprising a toothing with the crowning formed on the teeth of the toothing of the sintered component, the method comprising:

• calibrating the sintered component, wherein the sintered component is introduced into a recess of a calibration tool which comprises a forming chamber defined by at least one forming wall,
• wherein in the forming wall a crowning is formed which is inverse to the crowning of the sintered component to be formed by molding in the forming chamber, and
• thereafter removing the sintered component having the crowning formed on the teeth of the toothing from the calibration tool through ejection by a punch,
• wherein the size of the forming chamber of the calibration tool remains unchanged at least for the time period beginning with the insertion of the sintered component into the calibration tool and ending after the removal of the sintered component from the calibration tool through ejection by the punch,
• wherein the crowing of said calibration tool being inverse to the crowning to be formed on the sintered component is asymmetrical in an axial direction and wherein a radius of curvature of the inverse crowning becomes greater in the direction from a first end face to a second end face of the calibration tool, and wherein said calibration tool is made from a one-piece rigid metallic material.
