PROBLEM TO BE SOLVED: To improve a method and apparatus for producing a pot-shaped sheet metal part having inner teeth and outer teeth so that a sheet metal part having an outwardly oriented flange can also be formed with less required space and lower production cost of a forming head.SOLUTION: In a method for producing a pot-shaped sheet metal part having inner teeth and/or outer teeth extending toward a pot central axis, a pot-shaped sheet metal part 9 having no teeth formed is inserted into a die 5. Then, by means of relative movement between the pot-shaped sheet metal part and profile rollers 22 associated therewith, a profile is rotated on the pot-shaped sheet metal part by the profile rollers applied to the pot-shaped sheet metal part. Thus, inner gear teeth and outer gear teeth alternately arranged are applied to the pot-shaped sheet metal part. The profile rollers form the pot-shaped sheet metal part from an inside toward an outside in a radial direction. The profile rollers rotate along the inner circumference of the pot-shaped sheet metal part. |
