The present invention relates to a method for manufacturing a wire feed gear for manufacturing a zipper, and more particularly, to a method for manufacturing a wire feed gear for manufacturing a zipper used to intermittently upwardly feed an element-molded wire having a Y-shaped cross section.

Generally, a zipper attaches a piece of metal or plastic, such as a tooth, to a cloth tape. Next, two rows of cloth tapes with interlocking teeth were pushed and pulled by the handles attached to the hooks. These zippers are widely used in wallets, jumpers, bags, etc., and are widely used because they have a wide range of uses in real life.

In manufacturing such a zipper, the wire feed intermittently feeds up an element (zip of tooth) formed wire rod having a Y-shaped cross section by a predetermined amount. And the transfer ram attached to the top of the carter cuts the element by sliding in the horizontal direction.

As described above, in the manufacture of such a wire feed, the alloy steel is easily worn and subjected to heat treatment, and this heat treatment causes a warp phenomenon in which the gear part in which the roller gear and the guide gear close to each other are turned back. In addition, the conventional gear twisted due to heat treatment has a wire feed guide roller and a feed roller, so it is difficult to grind the gear when the gear is hit by grinding.

As a result, the wire feed gear causes an error in supplying the element-molded wire upward at a desired interval, thereby preventing the opening and closing of the produced zippers from being smooth.
