Case-hardened drive pins fastening method, involves attaching counter bores extending shearing blades at side into through-holes by laser cuttings, and fastening drive pins by material flow resulting from associated riveted bolts
The method involves producing through-holes (12, 13) by laser cuttings in shearing blades (2, 3). Counter bores (20, 21) extending the shearing blades at a side are attached into the through-holes by the laser cuttings. Case-hardened drive pins (16, 17) are fastened by a material flow resulting from associated riveted bolts, where laser flame cuttings are utilized as the laser cuttings. Production of the counter bores takes place with a large surface roughness.
