施例である。 The present invention is characterized in that the small ring and the guard rod are integrally formed simultaneously by punching from a single metal plate. The embodiment will be described below with reference to FIGS. 4 to 7. In the first step of the present invention, as shown in FIG. 4A, zigzag-shaped notches 7 are punched out, leaving strips 6a with some width on both sides of the rectangular metal plate 6 in the longitudinal direction, and comb teeth 6b are formed. Form. Accordingly, the metal plate 6 is divided into two guard blank plates each having a band edge 6a and a comb tooth 6b by this punching. FIG. 4B shows another embodiment of the present invention in which a slit 8 is punched out instead of the notch 7 and cut along the XY line.

A small ring 9 is formed by bending the vertically bent band side 6a into a circular shape as shown by arrow a to form a small ring 9 as shown in FIG. Through this step, the comb teeth 6b are expanded radially to form the guard rod 10.

ドをうることができる。 The third step of the present invention is to bend the radially expanded guard rod 10 into a substantially L shape as shown in FIG. be. When the two half-guard large rings 11 thus obtained are joined together, the main guard is formed. The diameter of the small ring 9 of the electric fan guard of the present invention is determined by the length l of the metal plate 6, and the length of the guard rod 10 is determined by the width m of the metal plate 6.
Since the width and density of the guard rod 10 are determined by the width n of the cut 7 or the slit 8, these l,
By setting m and n, a fan guard of a predetermined size can be obtained.

べた本発明の目的を達成する効果を有する。 As described above, the electric fan guard of the present invention is
A guard blank plate having a band side 6a and comb teeth 6b is formed by punching a rectangular metal plate 6, and the band side 6a is bent at a right angle and then bent into a circle to form a small ring 9. The comb teeth 6b are expanded radially to form guard rods 10, and the plurality of guard rods 1
0 into a roughly L shape and connect the tips of these to the large ring 1.
1, the manufacturing process is simplified and streamlined, and productivity is significantly improved compared to the conventional method shown in FIG. 3, in which the small ring 1 and the guard rod 3 are manufactured and assembled separately. . In addition, the uniformity of the product is higher than that of the conventional method, which has the effect of achieving the object of the present invention stated at the beginning.
