摘要： Improved method and apparatus for interlocking hemmed together edges of inner and outer vehicle body panels with an improved interlock joint. The inner panel blank is draw stamped and provided with PLP holes in a stamping press. A plurality of conventional hardware components are then welded to the inner panel. Then interlock holes are formed by a piercing tool moving through the inner panel border from its outboard to its inboard side while the inner panel is held by clamps and PLP pins. The hole piercing punch thus leaves cold worked upset material slightly raised inboard, rather than outboard, around the pierced interlock hole margin. Then the inner panel subassembly is married to the outer panel and transferred to a hemming station and again precisely clamped and positioned by PLP pins, whereupon hemming press gates are operable for hemming the flange lip of the outer panel over the inner panel border. The final hemming steel of each gate carries staking punches that individually strike a precision registered portion of such hemmed lip to deform it into locking engagement with the associated interlock hole. The upset material is thus flattened and accurately worked into embedment into the interior surface of the hemmed flange lip, rather than into the interior surface of the outer panel, thereby avoiding creating read through problems on the outer panel.
摘要翻译： 改进的方法和装置，用于通过改进的互锁接头将内外车身板的边缘相互缠绕在一起。 内板坯件被冲压并在冲压机中设置有PLP孔。 然后将多个常规硬件部件焊接到内板。 然后，穿孔工具通过内侧边框从外侧移动到内侧而形成互锁孔，而内侧板由夹具和PLP销夹持。 因此，穿孔冲孔使得冷加工的材料在内侧略微凸起，而不是外侧，在穿孔的互锁孔边缘周围。 然后将内部面板组件与外部面板结合，并转移到折边站，并再次由PLP销钉精确夹紧和定位，然后折边加压门可操作用于将外板的法兰唇缘折叠在内板边框上。 每个门的最终折边钢带有打桩冲头，其单独地冲击这种卷边唇的精确登记部分，以使其变形成与相关联的互锁孔锁定接合。 因此，镦粗材料被压扁并精确地加工成嵌入到卷边法兰唇缘的内表面中，而不是进入外板的内表面，从而避免在外板上产生读出问题。

摘要： A press with both prehemming and final hemming tools or steels each driven by the same prime mover. Each steel is mounted on a separate carrier driven through separate toggle joints to advance and retract the steels for prehemming and final hemming of an upturned flange along an edge of a steel panel. To facilitate synchronizing the operation of at least two presses, the prime mover may be a screw and servo motor drive assembly.

摘要： A device for prehemming at least a portion of an upstanding flange of a sheet metal panel which has a tapered roller which is moved into engagement with the flange while moving the roller along the flange with its axis of rotation disposed in a path which is substantially parallel to the fold line of the flange along the periphery of the panel. The roller is journalled for rotation on an arm pivotally carried by a slide which is moved by a drive cylinder along a lineal path generally parallel to the fold line of the portion of the flange to be prehemmed. As the slide moves linearly the arm is pivoted to move the roller transversely by a follower carried by the arm and received in an elongate cam track having a portion contoured to impart pivotal movement of the arm to cause the roller to follow the desired path of travel substantially parallel to the fold line of the flange for prehemming the flange by bending it to an acute included angle relative to an adjoining portion of the panel.

摘要： A woodworking router has an electric motor driven router head (12) surrounded by a dust collection collar (20). Pneumatic means (26) control the height of the collar relative to the router head between (a) a raised position exposing the router head for tool changing; (b) a lowered safety position in which the collar provides a safety guard around the router head; and (c) an even lower scavenge position for cleaning the worktable without routing. A factory dust collection duct is connected to a dust extraction duct mounting the collar for establishing an air flow over the electric motor (10) for motor cooling.

摘要： A die post assembly that supports a metal panel in a position to allow an implement such as a roller or die steel to flange, pre-hem or hem an edge of the panel. A die post support surface is disposed on a panel support element and an edge member of the assembly. The die post support surface is shaped to support the panel and includes a bearing surface that supports an overlying portion of the panel against deformation as the marginal edge portion of the panel is bent in a flanging or hemming operation. The edge member includes the bearing surface and is supported on the panel support element. The edge member comprises a material more durable than the material of the panel support element. This material is sufficiently durable to allow the edge member to support a series of metal panels over a large number of hemming or flanging cycles without flowing or otherwise deforming due to heat and pressures typically generated in such operations.

摘要： An apparatus constructed to be received within an interior opening of a sheet metal panels to form a pre-hem and a complete hem about the periphery of the opening with a plurality of generally radially outwardly movable hemming plates or steels which are driven by an actuator to move from a retracted position within the opening to an extended position overlying a portion of the periphery of the opening to pre-hem a flange about the periphery of the opening. With the hem steels in their extended position, a second actuator displaces the steels towards the sheet metal panels to complete the folding or final hemming of the flange about the periphery of the opening. After forming the hem flange, the second actuator is reversed to move the hem steels away from the sheet metal panels and then the first actuator is reversed to move the hemming steels to their retracted position within and spaced from the periphery of the opening of the hemmed sheet metal panels so that the hemmed panels can be removed from the apparatus.
