发明名称 Apparatus for manufacturing a head suspension
摘要 A base material has a vibration damper provided detachably on a liner through an attaching surface. An apparatus is used when punching the vibration damper piece from the base material. The punched vibration damper piece is attached on an objective portion of a semi-finished head suspension. The apparatus includes a hollow punch and a punch drive mechanism. The hollow punch has a tooth portion at a distal end and a hollow internal surface that has a holding force larger than an attaching force of the vibration damper to the liner. The hollow punch punches the vibration damper piece out from the base material to hold the vibration damper piece on the hollow internal surface. The punch drive mechanism drives the hollow punch backward and forward in a punching direction, so that the vibration damper piece is punched with the tooth portion without punching out the liner.

主权项 1. An apparatus for manufacturing a head suspension used when punching a vibration damper piece out from a base material having a vibration damper provided detachably on a liner through an attaching surface and attaching the punched vibration damper piece on an objective portion of a semi-finished head suspension, comprising: a hollow punch having a tooth portion at a distal end thereof and a hollow internal surface that has a holding force larger than an attaching force of the vibration damper to the liner, the hollow punch punching the vibration damper piece out from the base material to hold the punched vibration damper piece on the hollow internal surface; and a punch drive mechanism driving the hollow punch backward and forward in a punching direction of the hollow punch so that the hollow punch punches the vibration damper piece with the tooth portion out from the base material without punching out the liner to hold the punched vibration damper piece on the hollow internal surface and then the hollow punch holding the punched vibration damper piece moves away from the liner to detach the vibration damper piece from the liner.
