Title:
ROLLING TOOL, AND ROLLING METHOD
Document Type and Number:
Japanese Patent JP2007307567
Kind Code:
A
Abstract:
To provide a rolling tool and a rolling method, by which rolling tool and rolling method, even teeth having a hard-to-roll tooth shape can be accurately rolled.
The rolling tool 1 is composed of a pair of cylindrical dies (a first die 1a, a second die 1b), and rolling teeth 3 have a leading part 3a. Therefore, a conventional process becomes unnecessary which narrows the distance between both cylindrical dies by advancing one of the cylindrical dies by a hydraulic means, etc. in order to make the cylindrical dies cut into the outer peripheral surface of a workpiece to be rolled. As a result, the rolling accuracy can be improved by suppressing the dispersion in making the dies cut into the workpiece.
