Abstract (en)
[origin: WO2018146262A1] The invention relates to a method and to a device (300) for producing a round solid or hollow profile (110) made of metal, which is formed on the outer circumference and/or inner circumference having a helical toothing (120). According to the invention, the profile (110) is produced by means of pulling or pressing through a die (320) having a toothing contour, wherein the toothing contour has a twist, and the die (320) or the profile (110) executes a rotational movement (D). The invention further relates to a method based thereon for producing helically toothed gearwheels.
