Device and method of coil-less electromagnetic pulse incremental forming for metal sheet

A device of coil-less electromagnetic pulse incremental forming for a metal sheet, comprising:

• a lathe (3), wherein a worktable (6) is disposed on a top of the lathe (3);
• a three-axis moving frame (7), wherein the three-axis moving frame (7) is disposed on a top of the worktable (6), and an induction block (10) is disposed on the three-axis moving frame (7);
• a sheet clamping table (18), wherein the sheet clamping table (18) is disposed on the top of the worktable (6) and is located below the three-axis moving frame (7), a sheet to be formed (2) is clamped on the sheet clamping table (18), and the sheet to be formed (2) is correspondingly arranged with the induction block (10);
• a mold (1), wherein the mold (1) is mounted on a top surface of the worktable (6);
• the mold (1) is located below the sheet to be formed (2) and correspondingly arranged with the induction block (10);
• a discharging component, wherein the discharging component comprises first discharging contactors (111) and second discharging contactors (112), the first discharging contactors (111) are disposed on the three-axis moving frame (7), and the second discharging contactors (112) are disposed on the sheet clamping table (18);
• the first discharging contactors (111) and the second discharging contactors (112) are correspondingly arranged with the sheet to be formed (2);
• a power supply system (5), wherein the power supply system (5) is electrically connected to the first discharging contactors (111) or the second discharging contactors (112);
• a control cabinet (4), wherein the control cabinet (4) is signal-connected to both the three-axis moving frame (7) and the power supply system (5), and the control cabinet (4) is electrically connected to an input module;
• wherein the first discharging contactors (111) or the second discharging contactors (112) are connected to the power supply system (5) through conductors (12), and a circuit breaker (13) is disposed on the conductor (12) between each second discharging contactor (112) and the power supply system (5).
