System for a sheet metalworking and a process thereof

A system (100) for sheet metalworking, 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);
• and
• a support member (4) movably disposed in the die (3), and configured with a base end and a tip end, the tip end proximal to the punch and defining a groove, the support member (4) is provided with a second electrical terminal (5) in the groove;
• and
• an insulation strip (9) provided between the support member (4) and the second electrical terminal (5);
• wherein, the support member (4) and the punch (1) contact a working portion (B) of the sheet metal (SM) at an axis (A-A) to supply electric current in pulses to a localized region (LR) of the working portion (B) for sheet metalworking,
• wherein the localized region (LR) is defined by a contact portion of a tip end (TE) of the punch (1) and a tip end (TE) of the support member (4) on either sides of the sheet metal (SM),
• wherein the electric current passes in the form of pulses from the tip end (TE) of the punch and the tip end (TE) of the support member (4) to the localized region (LR) of the working portion (B) on either sides of the sheet metal (SM).
