  • Patent number: 4908928
    Abstract: A method and apparatus for riveting two workpieces (10, 12) together by simultaneously upsetting both ends of a slug rivet (R) while maintaining the outer surface (16) of one of the workpieces (10) in a substantially constant fixed work plane (20) during riveting. The workpieces are held between two clamps (18, 28), one of the clamps (18) establishing the fixed work plane. After drilling, a slug rivet is placed within the drilled hole, and then a first riveting ram (42) is moved to establish a desired die cavity. A second riveting ram (58) is then moved until it just contacts the rivet. The rams (42, 58) are then simultaneously moved towards each other at equal rates to simultaneously form upset heads on both ends of the rivet.

  • Patent number: 4898319
    Abstract: A brazing oven includes an arrangement employing a gas curtain or barrier to cover the port or opening of the oven whenever the door is opened. The curtain or barrier is formed by a region of flowing conditioned air directed across the opening. The flowing air curtain or barrier prevents gas from exiting the oven interior when the door is opened, and it also serves to replace or replenish any conditioned air which happens to escape from the oven interior. The air curtain or barrier is generated by a ported manifold and supply located either on the oven housing exterior adjacent the opening or inside the oven housing adjacent the opening.

  • Patent number: 4864713
    Abstract: A method and apparatus for positioning tooling and riveting the apparatus including a frame provided with opposed riveting rams (96, 86) and clamps (34, 36). The first clamp (34) is extended above the work plane established by the outer surface of one workpiece (10) with the lower ram retracted. Next, the frame (26) is moved downwardly until the first clamp touches the workpiece. An encoder (140) measured the amount of first clamp collapse during overtravel of the frame after the first touch is sensed. The frame is now backed off this distance to establish a work line coextensive with the work plane. The lower clamp (36) is then raised to clamp the workpieces (10, 12) and drill carried by a sub-frame (66) will now drill aligned apertures through the workpieces. The subframe is indexed to another position to place rams (96, 86) is alignment with the apertures. The upper riveting ram (96) is then advanced to its full down position to set an upper cavity and is locked under high pressure.

  • Patent number: 4858289
    Abstract: Dimpling and riveting a workpiece wherein the workpiece is clamped, the dimpling, drilling and riveting occur sequentially while the workpiece is clamped, and the workpiece is heated prior to dimpling. During clamping a pressure foot force is applied to one side of the workpiece, and during dimpling a force is applied to the opposite side causing slight movement of the workpiece against the pressure foot force. The dimpled recess in the workpiece is about the shape of a truncated cone and a rivet-receiving hole is drilled through the workpiece in the recess. To provide a fluid-tight seal, the minor diameter of the truncated cone is made slightly greater than the diameter of the rivet-receiving hole thereby providing an annular step between the hole and the outwardly diverging wall of the dimpled recess. During upsetting of the rivet the workpiece material is compressed radially around the annular step to provide a fluid-tight seal between rivet and workpiece.
