  • Publication number: 20140130567
    Abstract: Devices, systems and methods are disclosed which relate to a wire bending apparatus capable of both on and off-plane nose and mandrel bends. Exemplary embodiments of the present invention incorporate a center turret cluster with a plurality of radii possible, a nose-bending mandrel, and a mandrel-bending mandrel. This apparatus forms a bending head that is attached to a CNC wire bending machine. This combination allows increased flexibility in forming complex wire forms and cuts down secondary operations, such as operations from robot arms, sometimes associated with CNC wire bending. In addition, the turret cluster position in the center allows for bending support with mandrel bends or nose bending on the back side of the bending head, usually 180 degrees away from the normal bending area. This allows the manufacturing of double end-loop forms without the addition of external clamps or robotic manipulation.

Flanging and trimming members are retracted and a coil member positions EMF hemming coils opposite the flange. The hemming coils are then activated and apply EMF force to bend the flange of the outer panel to a 180 degree angle, overlaying the edge of the inner panel and forming a panel assembly having a hemmed edge. Optionally, if needed, the flanging member is then lowered against the flange to assure flatness of the hem.

  • Patent number: 5819578
    Abstract: There is disclosed a process and apparatus for producing reinforcement profiles on sheet metal panels wherein the profiles are obtained with the same metal sheet which constitutes the body of the finished shelf. The profiles are obtained by performing a drawing action so as to create a channel of inverted "C" shape and then performing a successive bending action capable of causing the reciprocal approach of the ends of its two parallel sides, obtaining, at the end of the operation, a shape in the form of an inverted isosceles triangle which constitutes the reinforcement profile.

  • Patent number: 5593708
    Abstract: A bending process including both preliminary and following steps takes place in one apparatus. A plastic pipe (6) is heated to a temperature in which it can be plastically deformed. The heated pipe is thereafter shoved into a pipe-shaped bending channel (27) of a bending tool, with the bending tool comprising two dies (9,10), each respectively defining a groove (14,13) which together form the bending channel. Finally, a cooling agent is allowed to flow through the bent pipe which is still in the bending tool. The thusly cooled pipe is removed from the bending tool after the dies are separated from one another. The apparatus to bend the plastic pipe comprises heating, bending, and cooling stations (1,2,3). The heating station comprises two heating fixtures, and the cooling station comprises a supply line (21,22) with a coupling joint (20) which can be coupled to an end of the pipe.

  • Patent number: 5487296
    Abstract: A universal cam unit for use in a power press comprising a driver assembly, a slide block to which the working tool is mounted, and a mounting bracket for coupling the slide block to the ram for movement therewith. The slide block is slidably mounted to move between a retracted and an extended position. The slide block and the driver assembly include parallel inclined bearing surfaces which abut when the pressure pad and the ram are lowered. As the ram motion continues, the inclined bearing surfaces slide against each other thereby causing the slide block to move from the retracted to the extended position. The movement of the slide block brings the tool into engagement with a workpiece disposed between the pressure pad unit and the lower die to perform a desired operation. The components of the universal cam unit may be disassembled and selectively replaced, so that the unit may be quickly and easily adapted for use in a desired application.

  • Patent number: 5253502
    Abstract: An apparatus for bending and forming sheet metal into U-shaped channel members is comprised of a support block for supporting a blank of sheet metal in a centered position, a pair of rollers that engage in rolling contact against opposite ends of the sheet metal, and an anvil around which the sheet metal blank is formed into the U-shaped channel member. The sheet metal blank is formed over opposite sides of the anvil by the rollers engaging in rolling contact against the opposite ends of the sheet metal blank. As the rollers roll over the opposite ends of the sheet metal blank, they bend and form the sheet metal ends into channel bends having acute interior angles. When the rollers are removed from the sheet metal ends, the resiliency of the sheet metal causes the channel bends to spring back from their acute angle configurations to right angle configurations.
