    • A sheet of material (111) having a plurality of bend-inducing structures (113) configured and positioned to produce bending along a bend line (115). The bend-inducing structures (113) have arcuate return portions (122) extending from opposite ends (121) back along the bend-inducing structures (113) toward the other return portion (122) and each return portion (122) has a length dimension and a radius of curvature reducing stress concentrations. Preferably, the length dimension of the arcuate return portion (122) is in excess of twice the thickness. The lateral distance, LD, to which the bend-inducing structures (113) is formed in the sheet away from the bend line (115) is preferably minimized by small radius arcs (125) which connect the return portions (122) to the remainder of the bend-inducing structures (113). A method of forming a structure (131) from a sheet of material (111) to resist cyclical loading is also disclosed, as is a method to increase the fatigue resistance of a structure (131) formed by bending a sheet of material (111) along a bend line (115) having a plurality of bend-inducing structures (113).

    • A stamping tool and a method for deforming a part with the stamping tool are disclosed. The stamping tool may include an array of striking members (e.g., pins), each striking member capable of being actuated independently with respect to the other striking members. In some embodiments, the stamping tool is part of a system having a vision system and a computing device. The vision system is capable of scanning the part to determine a location or location in which the array of striking members will engage the part. The deforming operation can include a rework operation subsequent to another process, or alternatively, the deforming operation can include deforming the part such that the part includes a three-dimensional shape. Also, the part can be a two-dimensional or three-dimensional part made from metal (e.g., aluminum, steel) or plastic.
    • 公开了一种冲压工具以及用冲压工具使部件变形的方法。 冲压工具可以包括击打构件(例如,销)的阵列,每个击打构件能够相对于其他击打构件独立地致动。 在一些实施例中,冲压工具是具有视觉系统和计算装置的系统的一部分。 视觉系统能够扫描部件以确定撞击部件阵列将啮合部件的位置或位置。 变形操作可以包括在另一过程之后的返工操作,或者替代地,变形操作可以包括使部件变形,使得部件包括三维形状。 此外,该部件可以是由金属(例如铝,钢)或塑料制成的二维或三维部件。
