Method and device for producing an internally and externally toothed pot-shaped sheet metal part using a forming head

摘要

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.

1. A method for producing an internally and/or externally toothed pot-shaped sheet metal part (9) having teeth extending toward the pot central axis, wherein an un-toothed pot-shaped sheet metal part (9) is inserted into a die (5, 5a) and then, by means of a relative movement between the sheet metal part (9) and associated forming bodies (profile rollers (22)), a profile is rolled onto the pot-shaped sheet metal part (9) by the forming bodies (profile rollers (22)) applied to the sheet metal part (9, 9-1) and alternating internal and external gear teeth are thus applied to the sheet metal part (9), characterized in that the forming bodies (profile rollers (22)) form the sheet metal part (9) oriented radially from the inside toward the outside, in that the forming bodies (profile rollers (22)) roll along the inner circumference of the sheet metal part (9).
