ABSTRACT:
A method of producing a flanged bush comprising the steps of: preparing a die having a through bore of a configuration conforming with the outer configuration of the flanged bush to be produced, and a flange-forming punch having a large-diameter portion of a diameter equal to the outside diameter of the flanged bush and a small-diameter portion of a diameter equal to the inside diameter of the bore in the flanged bush to be produced; inserting, by a coining punch, a cylindrical stock axially into the bore in the die from one axial end of the latter; and driving the flange-forming punch into the bore in the die from the other axial end of the latter so as to press the inner end of the stock, thereby to form the flange.
