    摘要: The die cushion force setting apparatus according to an aspect of the present invention allows die cushion forces (component forces) acting on plural driving shafts (4a) to be set easily, makes it easy to apply strong or weak die cushion forces to a complex-shaped drawn part in a plane of a cushion pad (2), and provides a smooth die cushion force distribution. An operator manually enters (step S18A) a total die cushion force, axial component force of a left front hydraulic cylinder (4LF), and center-of-force position by operating an input device (A1). Based on the information entered via the input device (A1), the numerical computing device B1 calculates (step S18B) axial component forces of three hydraulic cylinders (4LB, 4RF, 4RB) through numerical computations. The one axial component force thus entered and three axial component forces thus computed numerically are set (step S18C) as the axial component forces of four hydraulic cylinders (4LF, 4LB, 4RF, 4RB).

    摘要: A condition setting calculation device (104) compares an actual performance value of a material characteristic transmitted from a material characteristic data providing device (101) via a network (105) with a standard value, and corrects forming conditions such as a forming speed and a blank-holder pressure in accordance with the compared result. A control device (103) controls a press-forming device (102) to start a press-process of a material to be processed (300) with the corrected forming condition. Accordingly, it becomes possible to reduce occurrences of cracks and wrinkles as much as possible when the material to be processed (300) is press-processed, and to obtain good products of substantially identical shape.

    摘要: The invention relates to a method and an arrangement in a press tool for reducing the relative speed at which a moveable sheet metal holder impacts against a press upper part for transmitting a working force or is separated therefrom on completion of pressing. The invention is characterised in that the force for acceleration of the sheet metal holder is transmitted from the press upper part by way of a mechanical transmission device fitted to the sheet metal holder in such a way that an initial movement is imparted to the holder before the press upper part comes to bear against the sheet metal fabrication and sheet metal holder, and that only then does the press uper part impact against sheet metal fabrication and sheet metal holder and for depression of gas-filled springs arranged adjacent to and supporting the sheet metal holder.

A memory (130, 310, 322) is provided to store machine information relating to the press and necessary to determine optimum values for the operating conditions. Die set information relating to the die set and necessary to determine the optimum values are received through a data input device.
