The invention relates to an apparatus for working, in particular for working without machining, for example for separating and/or forming, a web of material, having a plurality of individual tools for different manners of working the web of material with designated workpieces temporarily held therein, and having a machine direction along which the web of material with the designated workpieces and the plurality of individual tools can be moved incrementally relative to one another in such a way that the web of material can be worked multiple times within one work cycle by means of the plurality of individual tools, wherein the individual tools are designed as individual modules which can be fixed to one another to form an individual module cluster, but can be detached as well.

A press die includes: a die base; a plurality of die members arranged on the die base so as to produce a forming surface; a plurality of shims each of which is interposed between the die base and each of the plurality of die members; and a frame that surrounds the die base, the plurality of die members, and the plurality of shims. Each of the plurality of shims has a hardness higher than the plurality of die members. A regulating means that carries out a regulation so that an amount of displacement of each of the plurality of die members caused by pressure applied during press forming becomes smaller in proportion to proximity of the die member to the frame is provided between the die base and the plurality of die members or provided on the die base.

A hot-forming press (100) comprises a lower press assembly (102) and an upper press assembly (108). The lower press assembly (102) is movable along a vertical axis and comprises a lower die (106), and a lower hot-box portion (104), configured to receive the lower die (106). The upper press assembly (108) is movable along the vertical axis above the lower press assembly (102) and comprises an upper die (112), and an upper hot-box portion (110). The upper hot-box portion (110) is configured to receive the upper die (112) so that the upper die (112) is positioned opposite the lower die (106). The lower die (106) and the upper die (112) are configured to apply a forming pressure to a workpiece (114) that is received between the lower die (106) and the upper die (112). The lower hot-box portion (104) and the upper hot-box portion (110) are configured to heat the workpiece (114).

A stretch forming device includes a die and gripping portions gripping both end portions of an elongate material. The cross-sectional shape of the die has a curved shape bulging a central side of a forming surface; the length in a longitudinal direction of the elongate material is less than that of the forming surface; a second die having a second forming surface along the forming surface is installed removably on a central portion of the forming surface; and the stretch forming device has a first mode wherein, when the second die is installed on the forming surface, only the second die is pressed against the elongate material while a tensile force is applied to the elongate material, and a second mode wherein, when the second die is removed from the forming surface, the die is pressed against the elongate material while a tensile force is applied to the elongate material.

A reconfigurable stretch forming apparatus includes an array of pins adapted to be individually adjustable in height to define a reconfigurable forming surface, a pair of counter-rotating workpiece gripping devices being provided on opposite sides of the array of pins, each gripping device having an arcuate support surface for supporting a workpiece and a clamp member for clamping a work piece against the arcuate support surface, a driver being provided for rotating the counter-rotating gripping devices in opposing directions to stretch the work piece over the forming surface.

The present invention provides a die capable of achieving rapid forming and quenching therein. The die includes an upper die, a blank holder and a lower die, where the upper die is composed of an internal solid die core and a thin-walled skin. Grooves in communication with each other are disposed between the internal solid die core and the thin-walled skin. In a forming stage, the grooves are not filled or filled with a heat insulating material such as a gas; and in a quenching stage, a low-temperature medium is introduced into the grooves. The die can be used to achieve rapid forming and quenching of metal materials of different types and thicknesses.
