  • Shield assembly for computer enclosure and pressing machine for making it
    Patent number: 6566597
    Abstract: A pressing machine (10) for combining metal members (16) and plastic members (14) of shield assembles (12) includes a workbench (60), a cylinder (54), a guide device (100), and a pressing device (200). The workbench defines channels (70) for receiving the corresponding plastic members thereon. The pressing device includes two pressing blocks (220) defining cross indentions (228) for receiving protrusions formed in the plastic members to allow the metal members to be downwardly pressed thereby causing the cross cuts defined in the metal member to engage with the cross protrusions of the plastic member, and a pressing bar (222) forming pressing feet (232) for downwardly pressing inclined plates (40) formed in the metal members to allow apertures (42) defined in the inclined plates to engage with projections (24) formed in the tabs (22) of the plastic members.
