Method for forming double torsion spring |
| abstract |
The present invention relates to a method of forming a double torsion spring. According to this embodiment of the present invention, a supplying step of supplying a circularly wound steel wire in a straight line; a transfer step in which the steel wire is transferred; a forming step in which the steel wire is pushed in a plurality of directions to form a double torsion spring shape; Cutting step in which the molded spring is cut; and a heat treatment step in which the cut spring is heat-treated, wherein in the conveying step, the steel wire is conveyed by a plurality of conveying rollers, and in the forming step, the steel wire is formed in the shape of the double torsion spring by a forming means. |
