Description

  The present invention relates to a hair clipper razor structure, and more particularly, to a hair clipper razor structure having high hair cutting efficiency and capable of cutting the hair cleanly.

  The clipper blade is generally composed of a fixed blade fixed and a movable blade stacked on the fixed blade, and cuts the hair by reciprocating the movable blade left and right and crossing the fixed blade.

In order to obtain a good cutting effect of the clipper blade and maintain durability stability, in the conventional technology, a thick and solid metal plate material is selected, and a comb tooth is formed at an acute angle by cutting with a grinder, Its thickness and structural strength were maintained.
FIG. 1A is a schematic view showing a state when cutting is performed by a conventional grinder to form a blade edge 111a, and a plan view of a cutting edge portion 111 formed after cutting is shown in FIG. 1B. A cross-sectional view is shown in FIG. 1C. FIG. 2A shows a razor tool completed by cutting the above-described conventional thick and solid metal plate material with the grinder 7. However, when cutting a thick and solid metal plate material with a grinder, there were the following defects (a) to (e).

(A) As shown in FIG. 2A, since the V-shaped alveoli 12 are formed between the blades 11, the movable blade 1 and the fixed blade 2 are overlapped with each other as shown in FIGS. 2B and 3A. 3A, since the bottom end of the V-shaped alveolar 12 becomes narrow as shown in FIG. 3A, the hair 5 entering the bottom of the V-shaped alveolar 12 is pressed when cutting the hair. Pushed back. For this reason, even after the hair 6 has been trimmed, the length may not be uniform and may become uneven.
(B) Since the bottom end of the V-shaped alveolar 12 is narrow as shown in FIG. 3B, the hair 5 entering the bottom of the V-shaped alveolar 12 is pressed and bundled as described above. The force applied when cutting the hair has to be increased, and the cutting efficiency may be reduced.
(C) Since the friction area at the bottom end is large, there is a possibility that the temperature of the blade rises and becomes high when used.
(D) Since the friction area is large, power consumption is high.
(E) The above-described processing method may increase the processing amount of the grinder, shorten the life of the grinder, and increase the processing cost.

As can be seen from the above description, a razor tool that cuts a thick and solid metal plate material with a grinder has the above-described drawbacks.
In order to remedy these disadvantages, a thick and solid metal plate material is pressed before cutting, the bottom edge between the two blades is bent inward, and the tank hole is arcuate The tank hole has a hair cutting function, the trimmed hair is neatly arranged, the hair cutting efficiency is improved, the blade friction area is reduced, the blade temperature is lowered, the power consumption and the grinder processing There was a need to reduce the amount.

  The purpose of the present invention is to first perform a cutting process after pressing a thick and solid metal plate material, thereby reducing the working time and work amount for cutting the grinder, and the consumption amount of the grinder. It is an object to provide a hair clipper razor structure that can reduce hair, and can cleanly align the hair with a razor tool, and increase the hair cutting efficiency to prevent the blade temperature from rising.

  In order to solve the above-described problem, according to the first aspect of the present invention, a razor tool structure of a clipper including a plurality of blade units, the both side surfaces of the front end of the plurality of blade units includes a cutter portion. Between the one side bottom end of one of the tooth units and the bottom end of the other tooth unit adjacent to the tooth unit A clipper razor structure characterized by having a hole is provided.

  The cutter part preferably has an acute angle part.

  It is preferable that the said tank hole has a taper and the bottom part of the said tank hole has an acute angle part which cut | disconnects hair.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

Reference is made to FIGS. FIG. 4 is a perspective view showing a raw blade structure of a hair clipper razor structure according to an embodiment of the present invention. FIG. 5 is a perspective view showing a partially processed blade structure of a clipper razor structure according to an embodiment of the present invention. FIG. 6 is a perspective view showing a processed blade structure of a clipper razor structure according to an embodiment of the present invention.
As shown in FIGS. 4 to 6, the clipper razor structure according to an embodiment of the present invention uses a movable blade as an example, but the structure of the razor tool of the present invention fixes the blade, Then, the movable blade 4 having a plurality of circular through holes 411 is press-molded by a press molding apparatus (not shown). The circular through-hole 411 is located on the flat surface 41 formed at the front end of the movable blade 4, and the movable blade 4 press-molded at this time is a half-processed blade.

  Please refer to FIG. 5 and FIG. As shown in FIG.5 and FIG.6, after that, the front end part 42 of the movable blade 4 in which the blade was half-processed was cut by the grinder (not shown) toward the circular through-hole 411 and arranged. A plurality of blade units 44 are formed. The cutter portion 441 on the side surface of the blade unit 44 is formed by cutting with a grinder, and the grinder cuts toward the circular through hole 411. Therefore, a tank hole 45 is provided between the two cutter portions 441 corresponding to each other. Is formed.

Further, the top surface of the front end portion of the movable blade 4 main body of the half processing blade has a front end portion 42. Since the bottom surface of the front end portion 42 has the flat surface portion 43, the top surface of the front end of the blade unit 44 after being cut by the grinder in the reworking process is formed on the inclined surface portion 442, and the bottom surface of the front end is formed on the flat surface portion 443. Has been. Therefore, when the cutting is completed, an acute angle portion 4411 is naturally formed in the cutter portion 441. Therefore, in the manufacturing process of the present invention, only two processes, that is, a press molding process and a cutting process using a grinder, are used.
In addition, the tank hole 45 has a taper (not shown), and the movable blade 4 and the fixed blade 2 intersect each other regardless of whether it is the acute angle part 4411 of the cutter part 441 or the taper of the tank hole 45. When is closed, the hair is cut. The taper of the tank hole 45 forms the bottom of the tank hole 45 at an acute angle having a cutting function.

  Please refer to FIG. As shown in FIG. 7, the manufacturing method of the movable blade of this embodiment includes the following steps (1) and (2).

(1) First, a half processing blade having a plurality of circular through holes 411 is formed by a press molding apparatus (step 801).
(2) The front end portion of the circular perforation hole of the half-processed blade is cut toward the circular through hole 411 by a grinder, and the two cutter portions corresponding to each other are cut, and between the two cutter portions corresponding to each other The tank hole bent inward is formed in an arc shape (step 802).

  As apparent from the manufacturing process described above, the razor tool structure of the clipper of the present invention is different from the manufacturing process of the conventional V-shaped tooth tub because the tank hole 45 is first formed at the bottom of the sword unit 44. When production processing is performed, a machining path for cutting and molding necessary for forming the blade unit 44 is shortened. Therefore, the machining amount of cutting molding is reduced, the machining efficiency is increased, and the consumption amount of the grinder can be reduced.

Reference is made to FIGS. 8A, 8B, 9A and 9B.
As shown in FIG. 8A, FIG. 8B, FIG. 9A and FIG. 9B, according to the present invention, the movable blade 4 and the fixed blade 2 are attached to the clipper 3 in an overlapping manner, and are shown in FIG. 8A, FIG. 8B, FIG. As described above, when the hair clipper razor structure of the present invention cuts the hair, the following advantages (1) to (3) are obtained.

(1) The state in which the pushed-in hairs 5 are pressed against each other can be reduced by the tank hole 45, and the hair 5 put in the alveoli can be prevented from being pushed back and pushed out when cutting the hair. Therefore, it is possible to prevent the hair 6 from being trimmed neatly and becoming uneven in length.
(2) The hair 5 entering the tub hole 45 is maintained in the original unbundled state, the bottom end of the conventional V-shaped dentate is narrowed, the hair is strongly bound, and the hair is cut only by applying a light force. Therefore, the hair cutting efficiency can be increased.
(3) As can be seen from a comparison between FIG. 8B of the present invention and FIG. 2C of the prior art, the contact surface 444 overlapping the fixed blade 2 of the present invention is formed by the serrated blade 11 and the fixed blade 2 of the prior art. When compared with the contact surface 113 which overlaps, the V-shaped alveoli 12 are formed between the sawtooth blades 11 of the prior art. The blade unit 44 of the present invention has a tank hole 45. Since the tank bottom of the tank hole 45 has an arc-shaped concave opening, the tank hole 45 of the present invention has a small contact area of the blade as compared with the conventional V-shaped tooth tank 12, so that the frictional resistance generated when operating is low. The amount of electricity consumed can be reduced, and the heat generated by friction can be reduced to prevent the blade from becoming hot.

Unlike the prior art, the hair clipper razor structure of the present invention has the following advantages (1) and (2).
(1) In the present invention, first, a thick metal plate material is pressed and then cut, and since a tank hole is formed at the bottom of the blade unit, The tank hole prevents the hairs to be pushed in from being pressed against each other, and when the hair is cut, the hair in the alveoli can be prevented from being pushed back and pushed back. Therefore, since the trimmed hairs are neatly aligned, it is possible to prevent the lengths from becoming non-uniform and not uniform. In addition, since the hair entering the tub hole is maintained in the original disjointed state, the bottom end of the conventional V-shaped tooth tub is narrowed and a hair bundle is formed, so that the hair is cut only by applying a small force. This can increase the hair cutting efficiency.
(2) The present invention reduces the contact area of the blade by the tank hole, reduces the frictional resistance generated when operating, reduces the power consumption, reduces the heat generated by the friction, and the blade becomes hot. Can be prevented.

  The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims of the present invention should be construed broadly including such changes and modifications.
