Abstract

PURPOSE: To compactly form a sleeve and to facilitate a work by forming plural recessed parts on the outer periphery, inserting into a sleeve the core formed with a gap part at the core part and pressfitting the die forming plural projecting parts to the outer periphery of the sleeve.
CONSTITUTION: The cylindrical core 1 on which outer peripheral face an annular recessed part 2 is plurally formed at specified intervals is fitted into a sleeve 5. The truncated conical gap part continuing in the longitudinal direction is formed at the core part of the core 1. After fitting the core 1 into the sleeve 5 the core is expanded by driving a wedge 4 in the gap part and fixed inside the sleeve 5. The dies 6, 6 formed with plural projecting parts 7 at the same intervals as those of the recessed part of the core 1 are press-fitted from the right and left parts to the outer periphery of the sleeve 5 and a compression force is exerted thereon to form an unevenness on the sleeve 5. The core 1 is finally removed from the sleeve 5. The sleeve is thus formed compacter at low production cost.
