초록 ▼

A method for forming a hard disk drive base plate with an extended height is described. The method may include forming an initial hard disk drive base plate, forming a filler shim, and forming a shroud. The method may also include joining the initial hard disk drive base plate, the filler shim, and the shroud to extend a height of walls of the formed initial hard disk drive base plate, and to form the hard disk drive base plate with the extended height.

대표청구항 ▼

1. A production system for forming a hard disk drive base plate with an extended height, comprising: a first stage of the production system to advance a blank cut from an extruded sheet through multiple stations of a transfer die assembly to forge and form an initial hard disk drive base plate;a second stage of the production system to punch a filler shim from a sheet of metal;a third stage of the production system to form a shroud, wherein the third stage of the production system further comprises a metal extruder to form a hollow bar with a cross-sectional shape that corresponds to a shape of a marrying surface of walls of the initial hard disk drive base plate, and a saw to cut a section from the hollow bar to form the shroud; anda fourth stage of the production system to join the initial hard disk drive base plate, the filler shim, and the shroud to extend a height of walls of the formed initial hard disk drive base plate and to form the hard disk drive base plate with the extended height. 2. The production system of claim 1, wherein the third stage of the production system performs a sequence of forgings on an initial blank to form the shroud. 3. The production system of claim 1, wherein the fourth stage is a welding stage further comprising: the welding stage to join the initial hard disk drive base plate, the filler shim, and the shroud, the welding stage to align a marrying surface of the initial hard disk drive base plate with a first marrying surface of the filler shim,align a marrying surface of the shroud with a second marrying surface of the filler shim, andweld along an interior path and an exterior path of the aligned initial hard disk drive base plate, filler shim, and shroud. 4. The production system of claim 1, further comprising: a first cleaning stage to clean the formed hard disk drive base plate with the extended height,a surface treatment stage to apply a surface treatment to the cleaned hard disk drive base plate with the extended height, wherein the applied surface treatment is one of an Electroless Nickel plating, Electro-coating, or Bimetal Black Electroless Nickel plating,a machining stage to perform one or more machining operations on the surface treated and cleaned hard disk drive base plate with the extended height to refine one or more parts of the surface treated and cleaned hard disk drive base plate with the extended height, anda second cleaning stage to clean the machined hard disk drive base plate with the extended height to produce a finished hard disk drive base plate with an extended height.
