Apparatus for forming continuous winding coil and method of controlling the same

A method of controlling an apparatus for forming a continuous winding coil, the method comprising:

• securing a coil to a transfer unit;
• performing an initial bending by forming a leg portion and a crown portion in the coil using an upper mold tool of an upper mold unit and a lower mold tool of a lower mold unit;
• performing an upper-mold-side bending, after the initial bending, by moving the upper mold unit while maintaining the lower mold tool stationary, and forming a leg portion continuously following the crown portion using the upper mold tool;
• performing a lower-mold-side bending, after the upper-mold-side bending, by moving the lower mold unit while maintaining the upper mold tool stationary, and forming a crown portion continuously following the leg portion using the lower mold tool;
• and
• a returning operation of transferring the coil by a set distance by the transfer unit, and transferring the upper mold unit and the lower mold unit to initial positions thereof.

An apparatus for forming a continuous winding coil, comprising:

• a transfer unit configured to secure and transfer a coil in a longitudinal direction thereof;
• an upper mold unit including an upper mold tool supply component configured to selectively provide one of a plurality of upper mold tools for forming a leg portion of the coil, and an upper-mold-side bending component configured to engage with the selected upper mold tool to bend the coil;
• a lower mold unit including a lower mold tool supply component configured to selectively provide one of a plurality of lower mold tools for forming a crown portion of the coil, and a lower-mold-side bending component configured to engage with the selected lower mold tool to bend the coil;
• and
• a control unit configured to independently control the upper mold unit and the lower mold unit to sequentially form alternating leg portions and crown portions in the coil.
