Abstract
A method for producing a component which has a toothing profile includes, in a first step, inserting a component blank into a mounting of a tool device configured to receive a pressing force during a movement of a pressing part of the tool device in a vertical movement direction, and, in a second step, pressing the toothing profile into the component blank using a rotational body which is coupled to the pressing part via a joint rod, when the pressing part is moved in the movement direction, the rotational body is pressed in a direction of the component blank and rolls along the component blank such that the toothing profile is formed.
Claims20
A method for production of a component having a toothing profile, comprising
- In a first step, inserting a component blank into a mounting of a tool device configured to receive a pressing force in response to a pressing part of the tool device being inserted in a vertical movement direction,
- in a second step, pressing the toothing profile into the component blank using a rotational body coupled to the pressing part via a joint rod, wherein when the pressing part is moved in the vertical movement direction, the rotational body is pressed in a direction of the component blank and roll along the component blank so that the toothing profile is formed.
The method according to claim 20, wherein the negative molds corresponding to each cold-forming stage differ in terms of at least one of a toothing diameter and a toothing depth.
A tool device for producing a component having a toothing profile, comprising:
- a vertically movable pressing part,
- a mounting configured to receive a component blank, and
- a rotational body and a joint rod which couples the rotational body with the pressing part, the joint rod connecting the rotational body to the pressing part in such a way that, when the pressing part is moved vertically to form the toothing profile, the rotational body is pressed in a direction of the component blank and rolls along the component blank.
