US Patent No: 5833777
Base plate for suspension assembly in a hard disk drive with a hardened flange and soft hub
Abstract
A base plate for a suspension assembly in a hard disk drive wherein the base plate has a hardened flange and soft hub. The base plate is stamped in a progressive die in a sequence of forging and coining operations. The base plate is subsequently fully annealed to allow the material to yield at a low stress level so that the hub will create a press fit against the inner wall of an actuator arm boss hole. The base plate is passed through a secondary coining operation following the annealing step to work-harden the flange portion only. The result is a base plate with a flange portion that is hardened and a hub portion that is softer than the flange portion. The advantage is that the hardened flange is more resistant to deformation of a load beam welded thereto and the hub is more disposed to plastically deform and harden during swaging which is desirable for maintaining a press fit.
