Description

The present invention relates to a method for manufacturing a barber for barber.

  A barber for barber is for cutting hair so that it is thinned out. Basically, one cutting blade part of two wrinkle members is formed in a comb shape, and a blade is formed at the tip of each comb body. When hair is cut, part of the hair escapes into the gap between the comb bodies, and the hair sandwiched between the comb-shaped blade portion and the opposing blade portion is cut.

  By the way, in the formation of the comb shape of the barbarian scissors, grooving by cutting with a grinding wheel or wire, electric discharge machining, or the like is adopted, and the shape of the comb body by the above processing has a rectangular cross section. In the rectangular cross section as it is, since the hair surface is damaged when the hair abuts against the corner ridgeline of the comb body, it has been proposed to chamfer.

  For example, Japanese Utility Model Laid-Open No. 56-56882 (Patent Document 1) shows that chamfering is performed by a processing means similar to comb-shaped grooving. Japanese Utility Model Laid-Open No. 6-58872 (Patent Document 2) discloses that the comb ridge line is a curved surface, but does not disclose the processing means.

  Further, Japanese Patent Laid-Open No. 10-174788 (Patent Document 3) discloses means for chamfering on the outer peripheral surface of a rotating grindstone, and Japanese Patent Laid-Open No. 10-216373 (Patent Document 4) discloses a rotating grindstone. Means for chamfering on a disk surface is disclosed.

  Moreover, it is also disclosed in Patent Document 4 that buffing is performed from the front and back of the blade portion as deburring after chamfering.

Japanese Utility Model Publication No. 56-56882. Japanese Utility Model Publication No. 6-58872. Japanese Patent Laid-Open No. 10-174788. Japanese Patent Laid-Open No. 10-216373.

  As described above, chamfering the corner ridge line of the comb body and further buffing from the front and back of the blade part, the chamfered part is polished and a smooth finish can be obtained, but the side part of the comb body is buffed. It cannot be applied effectively. Even if electrolytic polishing is employed to polish the entire blade portion, the electrolytic solution may not enter the intercomb space, and complete polishing cannot be performed.

  Due to the uncertainties of these polishing treatments, when the hair comes into contact with the side surface of the comb body, the hair is caught on the side surface of the comb body and the hair is not smoothly pulled out. Accordingly, the present invention proposes a barber-made candy that has been subjected to complete polishing of the side surfaces of the comb body.

The method for manufacturing a barber scissors according to the present invention comprises two scissors members each having a finger hole on one end and a blade on the other side. The two scissors members are crossed and the crossing is pivoted. In a barber scissors with the blade part of one scissor member as the comb blade part and the other as the sword blade part, chamfering the corner ridge lines on the front and back of the comb body with a rectangular cross-section processed into a comb shape, and then buffing In addition, the entire front and back of the comb blade portion, the chamfered surface, the chamfered ridgeline, the side surface portion of the comb body, and the back surface portion of the gap of the comb body are completely polished by code polishing, and the portion is formed on a completely polished surface. is there.

  By adopting the above-mentioned configuration, the corner portion that becomes the chamfered ridge line of the comb body of the cocoon is rounded, and the side surface portion and the back surface portion of the comb body become the polished surface, so that the hair can be smoothly removed during use. It is easy to use and can prevent the hair from being damaged.

  Next, an embodiment of the present invention will be described. The scissors shown in the embodiment is basically the same as the previous one, and two scissors members A are provided with finger holes 1a, 1b on one end side and blades 2a, 2b on the other side. , B, crossing both hook members A, B at the center, and pivoting the crossing part C. The blade part of one hook member A is the comb blade part 2a, and the other hook member B The blade portion is a narrow blade-like blade portion 2b.

  In particular, the present invention is characterized by the means for manufacturing the comb blade portion 2a. As usual, each comb is formed into a comb shape by grooving (formation of a comb body gap) by cutting or electric discharge machining using a grinding wheel or wire. The body 21 is formed in a rectangular cross section (FIG. 2A).

  Next, chamfering is performed on the front and back corner ridgelines (including the inner surface of the comb body gap) 22 of each comb body 21 with a grinding wheel D. However, the shape of the chamfered surface 23 of the corner ridge line 22 of the comb body 21 is not necessarily the same shape on the front and back sides, and may be a shape that can be easily polished corresponding to the polishing means selected in the next polishing step.

  Blade cutting is performed before and after the chamfering, and predetermined quenching is performed after the chamfering and blade cutting.

  The comb blade portion 2a is polished as a finish after the quenching process. The polishing is performed by polishing the side surface portion 24 and the back surface portion 25 of the comb body 21 with the polishing code E, and the entire surface of the comb blade portion 2a with the polishing buff F. It is to be polished (FIG. 2B).

  The side surface portion 24 and the back surface portion 25 are formed into a slight arc-shaped surface by polishing with the polishing code E, and the boundary ridge line (chamfered ridge line) 26 between the chamfered surface 23 and the side surface portion 24 is rounded, and the chamfered surface is formed by the polishing buff F The boundary ridgeline (chamfered ridgeline) 27 between the blade 23 and the front and back surfaces of the blade portion is also rounded. As a whole, the comb body 21 has an elliptical cross section approximate to a rectangle (but not limited to front and back symmetry), and the entire inner peripheral surface of the comb gap 28 becomes a completely polished surface by mechanical polishing.

  Thus, when a hair is prepared by attaching fingers to the finger holes 1a and 1b in the same manner as a general barb for scissors, a part of the hair escapes into the comb body gap 27 to realize the shearing. In particular, even if the hair that has escaped into the comb gap 28 abuts against the side surface 24 and the back surface 25 of the comb body 21 due to relative movement with the wrinkles, the hair is damaged because the portion is a polished surface. There is nothing. At the same time, the hair is not caught at all, so it is easy to use.

1 is an overall view of an embodiment of the present invention. Explanatory drawing of the manufacturing process of the comb blade part.
