ABSTRACT:
A coil spring shaper includes a table, a winding shaft unit, a material feeding unit, a cutter, and a material hanger. The winding shaft unit is fixed on an upper surface of the table, receiving linear material from the material feeding unit movable a rail on the upper surface of the table, and winding the material pinched by an automatic pincher on its winding shaft rotated by a motor into a half-finished coil spring, and cut material with a cutter located opposite to the winding shaft. The material hanger is located near the material feeding unit, dispensing the material to the material feeding unit.
