Claims

[Claims for Utility Model Registration] Each of the rolled surfaces is provided with a plurality of processed teeth, and the workpiece is relatively driven in opposite directions along straight lines parallel to each other with the workpiece sandwiched between the rolled surfaces. A pair of flat dies that form an odd number of peripheral teeth by rolling the outer peripheral surface of the workpiece, the first machining tooth located at the side end of the biting part of the flat die; a leading flat type die mounted on the leading side so that the leading flat die first comes into pressure contact with the workpiece; and a lag installed on the trailing side so that the first machining tooth lags behind the leading flat die and comes into pressure contact with the Loe member on the other side. In a flat die for odd-numbered tooth rolling consisting of a flat die, at a position adjacent to the first machining tooth of the delayed flat die,
A pressure-receiving convex that receives pressure applied from the first machining tooth of the advance flat die to the workpiece by contacting the workpiece at the same time as the first machining tooth of the advance flat die contacts the workpiece. A flat die for rolling odd-numbered teeth, characterized by having a section.
