System and method for forming a hairpin for motors

A method for forming a hairpin, the method comprising:

• unwinding a material coil wound around a bobbin by an unwinder unit;
• flattening the material coil supplied from the unwinder unit by flattening rollers;
• cutting the material coil supplied from the flattening rollers to a preset length by a feeding unit;
• and
• forming a hairpin having a head portion and a leg portion by
• press-molding the material coil of the preset length supplied from the feeding unit by a plurality of forming blocks,
• positioning a mold device of a forming unit corresponding to the hairpin to be formed to a home position,
• loading the material coil by a plurality of clampers of the mold device,
• primarily forming the head portion between an upper forming surface of a first forming block of the forming unit and a lower forming surface of a second forming block of the forming unit by lowering the first forming block while the material coil is disposed between the first forming block and the second forming block,
• forming the leg portion between a pair of forming roller units of the forming unit and slant surfaces of the second forming block, and
• secondarily forming the head portion between a forming groove formed in the first forming block and a forming protrusion formed in a third forming block of the forming unit after raising the first forming block by a preset distance.
