  • Method and device for producing an internally and externally toothed pot-shaped sheet metal part using a forming head
    Patent number: 9981296
    Abstract: A method for producing an internally and/or externally toothed pot-shaped sheet metal part having teeth extending toward the pot center axis, wherein an un-toothed pot-shaped sheet metal part is inserted into a die and then, by means of a relative movement between the sheet metal part and associated profile rollers, a profile is rolled onto the pot-shaped sheet metal part by the profile rollers applied to the sheet metal part and thus alternating internal and external gear teeth are applied to the sheet metal part, wherein the profile rollers form the sheet metal part oriented radially from the inside toward the outside, in that the profile rollers roll along the inner circumference of the sheet metal part.
