A method of assembling a part having radially outwardly directed spindles 4 into an encircling part 2 comprises forming a circular recess 9 in the end of each spindle, stamping in the enclosing part wall a number of studs 7, each stud being surrounded by an annular groove 8 deforming the part 2 to a polygonal shape 13, inserting the part 4 with the recesses 9 fitted over the studs 7 and restoring the part 2 to a circular section of slightly smaller diameter than before deformation. Apparatus for carrying out the foregoing method comprises a stamping tool comprising three elements each having a central bore surrounded by an annular rib, optionally surrounded by a flat shoulder, which elements produce respectively the stud 7, the groove 8 and a flat peripheral zone 15, and a die (10) having a conical throat followed by a cylindrical portion, the diameter of which is equal to the outside diameter of the finished part 2, Fig. 9 (not shown). |
