Description

[0001] APPARATUS AND METHOD FOR MAKING FILAMENT [0002]

The present invention relates to an apparatus and a method for manufacturing filaments, and more particularly, to a filament manufacturing apparatus and method for winding a filament wire material into a coil-shaped filament and thermally treating the filament wire to remove inertia.

Generally, a filament is used as a light source material of an illumination device such as an incandescent lamp, a halogen lamp, etc., and is formed by winding a wire material made of tungsten (W, Tungsten) and forming it into a coil shape and heat-treating it.

1 is a flow chart showing a conventional filament manufacturing method.

As shown in FIG. 1, the conventional filament manufacturing method comprises a filament forming step (S101), a moving (feeding) step (S102), and a heat treatment step (S103). The wire material is wound using a winder to form a coil-shaped filament (S101, filament forming step). Thereafter, the molded filament is moved to a separately provided hydrogen electric furnace (S102, moving step). Then, heat treatment is performed by heating the filament in a hydrogen electric furnace to remove the inertia of the filament generated during coiling (S103, heat treatment step).

However, in the conventional filament manufacturing method, since a device for winding a wire material to form a coil-shaped filament and a heat treatment device for removing the inertia of the filament must be separately provided, the manufacturing cost is increased and the working time is delayed The productivity is not good, and the space occupied by the equipment is large.

In addition, in the conventional filament manufacturing method, there is a problem that the angle of the leg portion, which is the terminal of both sides of the filament, is not maintained and deformation occurs in the heat treatment process of the filament made in the coil shape, thereby increasing the defect rate of the product.
