  • Publication number: 20250121423
    Abstract: A press system and a method of manufacturing a hot stamped structural component from a sheet blank within a press system is provided. The press system comprises a controlled atmosphere system and a press tool apparatus. The press tool apparatus comprises a lower body member, an upper body member, an upper die member, a lower die member, and a heating device configured to heat a sheet blank. The upper die member and the lower die member are configured to perform hot blanking with stamping and in-die quenching on the heated sheet blank in the atmosphere controlled by the controlled atmosphere system to form the hot stamped structural component. By controlling the atmosphere during formation of the hot stamped structural component generation of oxides scales are suppressed.

  • Patent number: 12138676
    Abstract: A system (100) for sheet metalworking comprising a punch (1) connectable to a press (P), wherein the punch (1) is configured with a first electrical terminal (2). A die (3) configured with a die surface (DS), to support sheet metal (SM). A support member (4) movably disposed in the die (1), the support member (4) is provided with a second electrical terminal (5). The support member (4) and the punch (1) contacts a working portion (B) of the sheet metal (SM) at an axis (A-A) to supply electric current to a localized region (LR) of the working portion (B) for sheet metalworking.
