Method of designing fold lines in sheet material

A method of designing fold lines in sheet material includes the steps defining the desired fold line in a parent plane on a drawing system, and populating the fold line with a fold geometry including a series of cut zones that define a series of connected zones configured and positioned relative to the fold line whereby upon folding the material along the fold line produces edge-to-face engagement of the material on opposite sides of the cut zones. Alternatively, the method may include the steps storing a plurality of cut zone configurations and connected zone configurations having differing dimensions and/or shapes, defining a desired fold line in a parent plane on a drawing system, selecting a preferred cut zone and/or a preferred connected zone which have a desired shape and scale, locating a preferred fold geometry along the fold line, the preferred fold geometry including the selected cut zone and the selected connected zone, and relocating, resealing and/or reshaping the preferred fold geometry to displace, add and/or subtract at least one of the connected zones, whereby upon folding the material along the fold line produces edge-to-face engagement of the material on opposite sides of the cut zones. A computer program product and a system configured for implementing the method of designing fold lines in sheet material is also disclosed.

Process of forming bend-controlling structures in a sheet of material, the resulting sheet and die sets therefor

A process of forming bend-controlling structures, such as slits, grooves or displacements (22), in a sheet of material (21, 121, 221, 321, 421, 521, 621,721). The bend-controlling structures (22) have central portions (26) extending substantially parallel to a desired bend line (23) on the sheet and end portions (27) which diverge away from the bend line (23). In one embodiment the process includes the step of forming the bending straps (24) between pairs of slit end portions (27) at a desired spaced apart distances along the bend line (23) with the straps (24) having a desired configuration, and the step of forming central portions (26) which connect the end portions (27) to complete the slits (22) using a separate die set. A plurality of end portion dies (51/54) can be used to produce end portions (27) of various shapes and straps (24) of various widths, and a single set of central portion forming dies (71/74) are used to connect the end portions (27). In other embodiments die sets producing a single end portion (27) or mirror image impressions (A,B) are used and preferably overlapped to produce the complete bend-controlling structure (22). A modular die assembly (500) also is disclosed in which the bend-controlling structures can be produced by modular die inserts (511-514, 611-614). Finally, a selection of die sets (722a, 722b, 722c) of differing length from a group of die sets can be made to position the bending straps (24) at desired locations along the bend line.

Punched plate material carrying-out system

A slider of the punch carry out unit is moved in the X-axis direction adjacent a punching section of the punch press machine before or after a plate material is punched into a punched product by a punch press machine. At the same time, a gravity center and a shape of the punched product are calculated and recognized on the basis of the manufacturing data. On the basis of the obtained gravity center and the shape of the punched product, the gravity center of the punched product is moved under the lift arm by the X- and Y-axis locating mechanism. Vacuum pads located just over the punched product are selected or discriminated. Then, the lift arm is lowered and the punched product is held by actuating only the discriminated vacuum pads. During this lift motion, it is preferable to bend one end of the punched product slightly upward to easily separate the punched product from the remaining flat plate material. After the punched product has been lifted, the punched product is moved horizontally away from the punch press, and is then lowered on the punched product supporting unit by releasing only the actuated vacuum pads. Since only the vicinity of the gravity center of the punched product is held by a minimum possible number of the vacuum pads, irrespective of the size and shape of the punched products, the number of the vacuum pads can be reduced.
