    摘要: The invention relates to a press-hardening tool (100) for producing hardened shaped sheet metal parts from a sheet steel material (400), comprising at least two tool parts which are movable in relation to each other in a working direction (D) and between which, under application of a pressure force (F) acting in the working direction (D), a heated sheet steel material (400) can be shaped and cooled and in the process hardened. It is provided that at least one of the tool parts (220) is formed in a segmented manner and has at least a first segment (221) having a shaped section extending transversely to the working direction (D) and at least a second segment (223) having a shaped section extending steeply with respect to the working direction (D), wherein the first segment (221) is arranged in a movable manner on the relevant tool part (220) and, when a particular pressure force (F) is exceeded, can yield (A) counter to the pressure force (F) applied, in order as a result to allow continued moving together of the tool parts and associated intensified pressing (B, C) of the second segment (223) against the sheet steel material (400).

    摘要: A curved surface forming device for an adjustable segmented mold board with square rams, consisting of an upper group and a lower group of adjustable molds (4) whose height can be adjusted, and a loading mechanism. The adjustable molds (4) are arranged in the loading mechanism and at least one group of adjustable molds (4) can move up and down under the drive of the loading mechanism. The upper group and the lower group of the adjustable molds (4) are respectively provided with M×N and (M - 1)×(N- 1) square rams (1) capable of swinging. The upper and the lower square rams (1) are arranged in an interlaced manner in both transverse and longitudinal directions. The square rams (1) are composed of a square plate (a) and the sphere (b) with the pressure imposition surface being a plane or a curved surface. The curved surface forming device can eliminate the crumpling and deformation generated in the board punching, reduce dents and improve processing quality.

    摘要: The invention relates to a method and a tool for producing structural parts from sheet metal which have a vault-structured reinforcement zone (4) and adjacent, flat connecting zones (8, 9). Starting material for producing said structural parts are vault-structured blanks (1) that are smoothed during shaping in the area of the connecting zones (8, 9) while the vault-structured structure remains unchanged in the area of the reinforcement zone (4). According to the invention, the structural parts are produced using an embossing die (14) that comprises a matrix (16) and a two-part die (15) which consists of a fixing die (26) and a shaping die (27). The blank is first fixed in the area of the vault-structured reinforcement zone (4) vis-à-vis the fixing die (26) by a fixing element (18) that advances the matrix (16). The connecting zones (8, 9) are then drawn between the matrix (16) and the shaping die (27).
