  • Patent number: 11358204
    Abstract: A method of forming a vehicle panel includes deforming a sheet metal workpiece between stamping tools to form a first and second edges that converge at a corner of the workpiece's main surface. The first edge is defined by a junction of the main surface and a first flange. The second edge is defined the main surface and a second flange. Forming the first and second edges includes deforming the workpiece so that the second flange has a first region bent to a first angle relative to the main surface and an unwinding region bent to an angle that unwinds from the first region as the second flange approaches the corner. The method includes deforming the workpiece between a second set of stamping tools that deform the first flange and the unwinding region of the second flange until the first and second flanges are bent greater than 90°.

    Abstract: A method and system for flanging a metal part is provided to improve the final dimensions of the part to a desired shape. Residual stresses from flanging operations can distort a final shape of the metal part. This disclosure provides an initial flanging step in which metal gainers are formed into the metal during a first flanging step. The metal gainers provide an increased amount of metal at select regions. Then, during a next flanging step, the metal gainers are smoothened or removed during that flanging step while the metal is additionally bent. The metal gainers help combat the residual stresses and allow the flange to better take the desired shape.

    Abstract: A triangular hemming and stamping apparatus includes a stationary base that mounts a lower die set. Three guide posts are triangularly positioned on the base and extend generally vertically from the base. An upper fixed superstructure is supported by the three guide posts and fixedly spaced from the base. An upper slidable structural member that mounts an upper die set is slidably mounted on the guide posts between the base and the superstructure. An actuator is mounted on the superstructure and connected to the upper slidable structural member within an area within the guide posts. The actuator is not connected to nor associated with the guide posts, and the actuator is operable to move the upper slidable structural member toward and away from the base to perform hemming and stamping on a workpiece.

  • Publication number: 20140331458
    Abstract: The pinching operation is facilitated. A hose clamp (H1) is formed by bending a strip-like plate material (1) into a ring-like configuration, and includes a first end portion (5) having a first pinching operation surface (9), and a second end portion (6) having a second pinching operation surface (15). A through-hole (7) is open near the center in the longitudinal direction of the first pinching operation surface (9). At the time of bending into ring-like configuration, expansion regions (19) arranged at both side portions in the width direction of the second pinching operation surface (15) are folded at folding edges (20) with respect to a proximal region (18), whereby the second pinching operation surface (15) is narrowed in the width direction and can enter the through-hole (7). After bending into ring-like configuration, the expansion regions (19) are unfolded at the folding edges (20) and regain a widened state.

  • Patent number: 8858853
    Abstract: A method and apparatus for manufacturing a tool for creating composite components. A sheet metal material is secured over a forming tool in an incremental sheet metal forming machine. The sheet metal material is incrementally shaped with a stylus to form a shape for the tool. The tool is removed from the incremental sheet metal forming machine when the shape for the tool is complete. Composite materials on the tool are laid up, wherein the shape of the tool provides a desired shape for a composite component.

  • Patent number: 8845438
    Abstract: A yoke is provided in which damage such as bending of a bolt for joining and fastening the base section of the yoke to the end section of a rotating shaft does not easily occur even when that bolt is excessively tightened. In the present invention, a force is applied to both a first flange section and a second flange section in a direction toward each other, and with the inner diameter of the base section elastically reduced, a through hole, screw hole and seating surface section are formed. After that, the force is released and the inner diameter of the base section expands by its own elastic force. Alternatively, with the inner diameter of the base section reduced, the through hole, screw hole and seating surface section are formed, after which the first flange section and second flange section are plastically deformed in the direction away from each other to expand the inner diameter of the base section.
