    摘要： A sheet metal component such as a car door is disclosed. The component includes an outer metal sheet having a groove formed therein, and an inner metal sheet having an edge forming a flange received into the groove. A filling material layer is inserted into the groove between the outer metal sheet and the flange. The outer metal sheet and the flange are welded to one another in holes of the filling material layer.

    摘要： A method for interlocking the hemmed together flanges of the inner and outer panels comprises the steps of forming a plurality of raised beads at spaced intervals along the length of the edge of the inner panel; placing the inner panel inside the outer panel with the raised beads facing away from the outer panel; and hemming the edge of the outer panel over the edge of the inner panel by a hemming punch having a plurality of slots therein located to register with the raised beads of the inner panel so that the outer panel is coined into interlocking engagement with the raised beads to thereby interlock the inner and outer panels together against relative movement. The raised beads preferably have a height generally equal to the thickness of the inner panel, and are preferably elongated in shape with the elongation extending in the direction either parallel or perpendicular to the edge of the panel. The slots in the hemming die preferably have a length longer than the mating raised bead of the inner panel to allow at least one millimeter of clearance between the panels at each end of the beads.

    摘要翻译： 一种用于联锁内外板的卷边在一起的凸缘的方法包括以下步骤：沿着内板的边缘的长度以间隔的间隔形成多个凸起的凸起; 将所述内板放置在所述外板的内部，其中所述凸起的珠子背离所述外板; 并且通过折边冲头将外板的边缘折叠在内板的边缘上，该折边冲头具有位于其中的多个槽，以与内板的凸起凸起对准，使得外板与凸起的凸起互锁接合 从而将内板和外板互锁在一起抵抗相对运动。 凸起的凸起优选地具有大致等于内部面板的厚度的高度，并且优选地是细长的形状，其伸长方向平行于或垂直于面板的边缘。 折边模具中的槽优选地具有比内板的配合的凸起长度更长的长度，以允许在珠的每个端部处的板之间至少一毫米的间隙。

    摘要： Method is disclosed for manufacturing a panel assembly comprised of an inner panel and an outer panel which are welded together at the peripheral portions thereof. The method comprises steps of forming a plurality of raised portions having projections in the inner panel along at least one peripheral portion thereof so that the raised portions project in a direction opposite to the outer panel, folding a peripheral portion of the outer panel over the peripheral portion of the inner panel so that the peripheral portion of the outer panel covers the raised portions in the inner panel, applying anvils to the outer panel at portions corresponding to the raised portions and applying welding electrodes to the peripheral portion of the outer panel which is folded over the raised portions of the inner panel so as to depress the peripheral portion of the outer panel to the raised portion simultaneously applying a welding current in series through at least two of the welding electrodes for welding the peripheral portion of the outer panel to the raised portion of the inner panel. The process is effective to prevent thermal deformations and depression marks on the outer panel.

    摘要： A machine designed to continuously progress a pair of elongated flat sheets of metal longitudinally through a plurality of cooperative dies which progressively in sequential steps gradually shape the two sheets into a duct having a rectangular cross-sectional configuration. The machine utilizes cooperative rotary dies to shape and form the duct in a continuous operation to a length equal to that of the sheets so that rectangular ducts of any desired length can be produced in an automatic operation by merely inserting into the machine a preprepared roll comprised of a pair of sheets of metal of the desired length, the sheets entering the machine at one end and leaving the same at the other end in the form of a continuous rectangular duct.

    摘要： A roller hemming device includes a backing metal, a guide roller, a bending roller, a pressing unit, and a swinging unit. The backing metal includes an abutment surface and a guide surface. The abutment surface is brought into abutment against a first panel member. The guide roller is moved in an extending direction of the guide surface with abutting against the guide surface. With being moved synchronously with the guide roller, the bending roller presses a bent peripheral edge portion of the first panel member via the backing metal such that the bent peripheral edge portion of the first panel member is pinched between the bending roller and the guide roller, and folds the bent peripheral edge portion of the first panel member back to a periphery edge portion of a second panel member. The pressing unit presses the bending roller toward the backing metal.

    摘要： A panel assembly includes an outer member and an inner member, which overlap each other and jointly have an edge that includes a distal end portion of the outer member and a distal end portion projecting from an end of the inner member. The distal end portions are fastened together by sheet metal seaming. Boundary regions of the inner member between the distal end portion, which is seamed, and the end, which is not seamed, have respective clearances defined in the end, and which are spaced away from a seaming range in which the distal end portions are seamed.
