属細線用のカッターに関するものである。DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention is mainly used for thread cutting of cotton, nylon, polyester and the like for textile machines such as yarn winding machines and looms, or gold, silver, aluminum, copper and the like. The present invention relates to a relatively soft metal wire cutter.

It cannot be cut off after a life of 0,000 times. In the case of a metal cutter, it is necessary to lubricate the sliding parts to prevent seizure. Since it is necessary to refuel, the environment of use becomes dirty and the work piece becomes unusable, which may deteriorate the quality. Furthermore, in the case of a metal cutter, chemical fibers are used in the manufacturing process for chemical fibers and the like, so that rust and corrosion easily occur.

And are made of zirconia. Reference numeral 3 is a fulcrum, and 4 is a cutting edge. In this cutter, as shown in FIG. 2B, the blade member has a warp ΔL in the longitudinal direction. As for the warp direction, convex warp or concave warp can be considered, and the combination thereof affects the sharpness and the life. As shown in FIG. 3 and FIG. 4, a convex shape on the cutting edge 4 side is displayed as (+) warp and a concave cutting edge 4 side is displayed as (−) warp, and the number of cuts per hour is 100 times. / Min cut,
(1) is a fixed cutter, (2) is a moving cutter, the upper side of the table is an example of a zirconia cutter, and the lower side is an example of a metal cutter. The experimental results of the relationship between warp and sharpness are shown in FIG. FIG. 6 shows the relationship between sharpness and life. From the results of Fig. 5 and Fig. 6, the zirconia cutter is + in the longitudinal direction.
It was confirmed that a long life was obtained by giving a warp of 0.2 to −0.2 mm.

発生がない。[Advantages of the Invention] The present invention is a cutter that combines two blade members made of zirconia ceramic and cuts an object with a shearing force as described above, and at least one of the blade members is +
The cutter has a longitudinal warpage of 0.2 to -0.2 mm and the sum of the warp widths of both blade members is -0.01 mm or less.The conventional metal cutter has a life of 1.4 to 1.5 million times. On the other hand, the cutter of the present invention has a long life of 10 million times or more. Further, in the case of a metal cutter, it is necessary to lubricate the sliding portion to prevent seizure, but in the case of the zirconia cutter of the present invention, it is possible to do without lubrication and it is not necessary to lubricate, so the operating environment Does not get dirty, and the work piece is beautiful and the quality is improved. Further, regarding chemical fibers and the like, rust and corrosion occur in the case of a metal cutter due to the manufacturing process and the use of chemicals, but the cutter of the present invention does not.
