Abstract: A projection coined onto a metal sheet (52), preferably an aluminum sheet, for projection welding the sheet to an adjacent metal sheet. The projection has a thickness greater than the thickness of the sheet on which it is formed. The wall (55) of the projection surrounds a first recess (1) and a second recess (63) is formed in a side of the sheet opposite the projection from which the metal cold flows to form the projection. A welding gun assembly having an improved low interia, fast response to the collapse of the projection welding the sheet having the projection to the adjacent sheet.

Abstract: Seam welding apparatus (50) with a bearing support arrangement for a transversely movable upper welding wheel (51). The upper wheel is non-rotatably secured adjacent one end of an elongate electrically conductive shaft (66), the other shaft end being rotatably supported within an electrically conductive bearing assembly (67) which transmits electricity thereto from an external source (63). A non-rotatable bearing housing (68) is pivotally supported relative to a machine frame (61) by a pivot (74) which extends adjacent the housing perpendicularly to the shaft, the pivot being disposed remote from the wheel. A pressure cylinder (81) and ram (82) are mounted on the frame, the ram being movably supported and acting downwardly onto a spring unit (83) and electrical insulator (84). The spring and insulator are rotatably supportingly engaged with the shaft adjacent the wheel. The housing and shaft are mounted on a movable slide (73) to which the ram is preferably coupled. The spring unit is coupled between the slide and shaft.

Abstract: A seam welding apparatus (50) having an improved bearing support arrangement for the transversely movable upper weld wheel (51). This upper weld wheel is nonrotatably secured adjacent one end of an elongate electrically conductive shaft (66), which shaft adjacent its other end is supported within a conventional electrically conductive bearing assembly (67) which rotatably supports the shaft and transmits electrical energy thereto from an external source such as a transformer (63). The nonrotatable housing (67) associated with the bearing assembly is pivotally supported on the machine frame by a pivot (74) which extends adjacent the housing in perpendicular relation to the shaft axis (53), with this pivot axis being disposed remote (D) from the weld wheel. A welding force generating assembly such as a pressure cylinder (81) and ram (82) are mounted on the machine frame, with the ram being movably supported and acting downwardly onto a spring unit (83) which has an electrical insulator (84) associated therewith. This spring unit (83) and its electrical insulator (84) in turn are rotatably supportingly engaged with the shaft (66) closely axially adjacent the weld wheel (51).

Abstract: An apparatus for accurate axial aligning of a hollow workpiece. An expandable mandrel is loosely receivable within the workpiece and capable of expansion into firm fixed contact therewith for supporting and locating same. Positioning means are disposed adjacent to and outside of the workpiece substantially in radial opposition to the mandrel, the positioning means including shoes for contacting the exterior wall of the workpiece at first and second circumferentially spaced points thereon. The shoes are supported on the positioning means for limited movement with respect thereto substantially axially of the mandrel. Means are provided for supporting the positioning means for linear and universally pivotal movement and for urging same toward the workpiece and mandrel for causing the shoes to engage the workpiece, forcible engagement of the workpiece by the positioning means prior to expansion of the mandrel causing the workpiece to contact and become precisely axially aligned with the mandrel, the contact and alignment being maintained as the mandrel expands into gripping relation with the workpiece.

Abstract: A multiple station workpiece positioning device for positioning a workpiece at different stations relative to welding apparatus for permitting the performance of a plurality of welding operations thereon. The workpiece is mounted on a worktable and is guided for movement in a predetermined pattern by guide means. The guide means comprises a template having guide groove means therein receiving and guiding a follower member secured to the worktable. The guide groove means has a plurality of obstruction means therein to prevent a continued movement of the follower member and to accurately position the worktable at a plurality of stations relative to the welding apparatus. The obstruction means are bypassable by a movement of the worktable so that the follower member moves away from and around the obstruction means to permit a continued movement of the follower member and the worktable in the pattern defined by the guide groove means to the next obstruction means. At each location of the obstruction means, the worktable is accurately positioned relative to the welding apparatus so that appropriate energization of the welding apparatus will accurately place a weld onto a workpiece.

Abstract: A strip end welding machine having a base on which is slideably mounted a horizontally reciprocating, annular frame. The strips whose ends are to be welded pass axially through the frame transversely of its direction of reciprocation. The frame carries a shear for trimming the ends of the strips to be welded and welding and planishing rolls energizable for joining the overlap strip ends. The machine includes base-mounted clamps on either side of the frame for gripping the strip ends to be joined. The clamps are spaced from the welding zone and include a clamp bed of magnetic material and a magnet disposed opposite the clamp bed to clamp a strip therebetween. Each of the clamp bed and magnet are provided with a nose made of nonmagnetic material, which noses project away therefrom towards the welding zone. Each of the noses has a guiding surface thereon, each of said guiding surfaces being offset back from the adjacent clamping surface of the clamp bed and magnet a distance such that the distance between said guiding surface is greater than the thickness of the strip but close enough to prevent a buckling of the portion of the strip extending from the clamp bed and magnet to the welding zone.

Abstract: A power pack assembly, usable for example in welding, having a transformer, includes at least a pair of rectifier units coupled to secondary conductors thereof. The rectifier units each includes a spaced pair of substantially parallel mounting plates having a plurality of diode stacks sandwiched therebetween. One of the mounting plates is segmented between each pair of diode stacks to permit flexing of the resulting segments thereof axially of the diode stacks. Means are provided for clamping the mounting plates fixedly with respect to each stack of diodes, whereby the flexibility of the segments of the segmented plate allows same to accommodate to varying axial dimensions of the several diode stacks.
