Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kind of spring forming machine, and more particularly, to a machine having a tool positioning device and an omnidirectional tool set, which is capable of processing a steel wire into a spring of various modes.

2. Description of the Related Art At present, springs are widely used in a large amount in industry, and there are many kinds and styles of springs, which are designed to have different shapes depending on the characteristics of the springs used, and machines for manufacturing them. Also changes with it. Today, with the diversification of spring styles, this is uneconomical, and there are some drawbacks when making traditional springs on the machine: The conventional spring making machine can only produce a single type and type of spring, and cannot effectively produce diversified springs. Conventional spring manufacturing machines on the market cannot manufacture springs having an irregular shape that bends at a specific angle, so when manufacturing such springs, secondary molding or tertiary molding is required. The need for molding has resulted in manufacturing time, expense and impracticality. Although the conventional spring making machine is provided with a multi-directional annular cutting tool, its working angle is fixed, and it is not possible to perform small-angle rotation working on the steel wire. A traditional spring forming machine performs a rotational movement in the axial direction by pinching a steel wire, but its structure is very large, and it was difficult to perform positioning due to inertia after rotation. In the conventional spring forming machine, when performing the retreat operation, the steel wire is easily bent between the wire feeding device and the directing device, and thus defective products are likely to occur. In view of the fact that the conventional spring forming machine described above cannot form a variety of springs, the inventor of the present invention bends or folds the steel wire at different angles in one device to obtain a desired shape. Research and development have been conducted to provide a spring forming machine that can manufacture springs.
