  • Publication number: 20240109400
    Abstract: Present disclosure discloses a reinforcement member (10) for a vehicle. The member includes a first component (1) made of steel and a second component (2) secured to a portion of the first component. The second component is made of a reinforced polymer. The reinforcement member with the combination of the second component and the first component is configured to absorb impact energy. The reinforcement member (10) of the present disclosure is lighter in weight unlike the conventional reinforcement members and is structured to absorb/attenuate significantly impact higher energy than the conventional beams.

  • Patent number: 11821052
    Abstract: The present disclosure discloses a method for improving yield strength of one or more workpieces. The method includes positioning the one or more workpieces in a punch and die assembly and operating the punch and die assembly such that, a plurality of surface protrusions are formed on the one or more workpieces. The plurality of surface protrusions are formed by plastic deformation on the one or more workpieces, to improve yield strength of the one or more workpieces. The present disclosure also provides an apparatus to improve yield strength of the one or more workpieces. The present disclosure is configured to improve yield strength of the one or more workpieces, without altering its mechanical characteristics.

  • Publication number: 20230067089
    Abstract: A system (100) for a sheet metalworking is disclosed. The system (100) 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.

  • Patent number: 11420246
    Abstract: The present disclosure discloses a method for improving fatigue strength of a workpiece (100). The method comprises positioning the workpiece (100) in a punch and die assembly (102). Operating the punch and die assembly (102) one or more times to imprint surface features (2) on a portion of a surface of the workpiece (100), wherein the surface features (2) induces compressive residual stresses at a sub-surface level of the workpiece (100), and improves the fatigue strength of the workpiece (100).
