Further utilizing the special shapes and structures of the tool set 55, the spring manufacturing machine is able to manufacture various springs with different shapes and styles. As illustrated in figure 9A and figure 9B, by the displacement of the feeding chuck 18 the metal wire is able to change its position relative to the tool set 55. Further accordingly changing the rotational direction of the tool set 55, the spring manufacturing machine is able to perform an upward curving or a downward curving.
  • a wire feeder driving mechanism for a spring manufacturing machine in accordance with the present invention has at least four merits.
  • First, the installation of the axial driving devices enable the feeding chuck of the wire feeder to perform a two-dimensional or three-dimensional approach to the tool set. This unique design exempts a spring manufacturing machine from using a complicated tool seat driving mechanism of a conventional art. The labor hours for adjustment of the tool set is thereby greatly cut down.
  • Second, the movement of the tool set of the present invention is linear. It is easy to quantify the position point of the tool set. The replacement or adjustment of the tool set can be performed by an ordinary operator.
  • Third, the displacement data of the axial driving devices is forward to the computer controller to automatically and precisely control the feeding chuck to perform a desired motion.
  • the feeding chuck of the present invention is able to perform a three-dimensional motion, the usage of a tool set is more efficient than that of the prior art.
  • the present invention therefore remedies the tool seat deficiency problem of the prior art.
