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.

Abstract: An automatic riveting apparatus includes a base (10), a feeding device (30), and a riveting device (50). The base has a U-shaped support frame (12). Two photoelectric relays (18) extend upwardly from the base. The feeding device includes two parallel sliding rails (32), a lower die plate (36) for supporting a workpiece (80), and a feed cylinder (34) driving the lower die plate to slide along the rails. The riveting device has an upper cylinder (52) and a riveting head (58). In operation, the feed cylinder is started up to drive the lower die plate together with the workpiece to a riveting position. The lower die plate touches a photoelectric point (48) to actuate the upper cylinder. A piston rod (60) of the upper cylinder drives the riveting head downwardly to rivet the workpiece. The piston rod moves back up, and the lower die plate returns to its original position.
