摘要： A method is provided for the formation of high precision metal slugs by cold forming. A metal column starting material is subjected to a preforming step in which the starting material is cold forged with a pair of upper and lower metal dies provided with concave recesses to produce a primary product having a barrel shape having a high degree of parallelism on the ends. The resultant primary product is subjected to an upsetting step in which the barrel shape is crushed while maintaining parallelism to obtain a secondary product. The resultant secondary product is then subjected to an ironing step in which the outer diameter of the secondary product is reduced to obtain a high precision slug having an outer diameter which is substantially the same as the outer diameter of the desired final product for which the slug will be utilized.

摘要： A joining structure comprises a shaft made of metal and a disc of metal more reducible than the shaft. The shaft has arcuate walls defined by a basic circle, and a plurality of projections each projecting from the basic circle and extending along the axis of the basic circle. The projections are spaced from each other so that the arcuate walls are disposed all between the projections. The disc has a hole of the same diameter as the basic circle. The shaft is forcedly inserted into the hole of the disc so that the projections cut into the disc to be rigidly joined to the disc with high concentricity between the shaft and the hole.

摘要： A method and apparatus for coupling two metallic members such as a shaft and a disc. The method includes forming an annular groove on a joint face or outer circumference of the metallic member having greater deformation resistance of the two members, for example, forming uneven portions on the bottom of the groove by knurling or the like. Working the other metallic member, for example, the disc; having smaller deformation resistance near its joint face so that the joint face opposing that of the other causes plastic deformation. Causing a part of the disc to fluidize and flow into the groove, thereby coupling both metallic members together.
