Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Public Expenditure of the Invention] The present invention relates to a shear Δ, and more particularly to a rotary type shaper that shears by rolling a helical blade connected to an outer blade across the field.

[Technical background of 11C] Conventional four-tary method
Structure O shown in the figure is known.

1 in the figure is a main body case, and an outer cutter 2 having a curved semicircular cross section is attached to one side of the case 1. An inner cutter body S having a drum-like overall shape is rotatably attached along the outer cutter 2. A beard debris storage chamber 4 is formed at one end of the inner blade body 3, and the armpit storage chamber 4 communicates with an exhaust hole 6 formed in the main body case 1 via a filter 5. Further, a battery 1 and a motor 1 are arranged in series in parallel with the inner blade body 3, and a belt 1- is connected between the nine goosees 9 provided on the motor 1 and the nine goosees 9a provided on the inner blade body 3. It is well-connected.

However, the inner blade S is as described above! - It has a shaft 11 for holding the truck a, and a drum 12 serving as a support is fixed to the shaft 11. A spiral groove IJ is formed on the outer peripheral surface of this P ram 110, and a holding groove 1j is formed in the protrusion 14 located between the grooves 13. A spiral blade 16 is fitted into and held in this holding groove 15.

This spiral blade 16 is positioned in the holding groove IJ, and one or both ends of the spiral blade 16 are attached to the dot 12 by caulking or other means.
is fixed.

Further, at a position on the opposite side of the outer cutter 2 of the inner cutter body J, an f-blade 11 is connected between the spiral cutter 1 and removes hair debris.
is provided.

In such a configuration, when the motor 8 is started, the inner cutter body 1 rotates, and the spiral blade 1g is connected to the outer cutter 2 with a predetermined pressure and rotated, thereby shearing is performed. The shaved beard debris falls into the groove 13 and is sent to the beard skin storage capacitor 4 by the feeding action of the spiral blade 15. At this time, the inner blade body 1 is rounded and the outer blade 1 has a function of 01m as an axial flow fan, and the outer blade 1 also sucks in outside air and exhausts it through the exhaust hole gi%6 through the filter I. Due to this) Hige Ao is stored in Hige R 114Kil mourning.

However, in the above-mentioned shear Δ of the Kuda-Tashi method, the spiral blade 1811 outer blade 111C'lll has an elasticity of 70%.
It applies pressure to the shape of the fruit, and has a sweet, jujube-like sharpness throughout. In addition, the rotary load is small, and the driving efficiency is good due to the round and cage #, and even with low output, sufficient behavior is achieved.

Furthermore, the resistance in the direction of locking! IL also has full rotation angle fKI #1
0@
have a long length.

[Background technique IIO hidden point]

However, as mentioned above, the nine conventional □a-Tari method O-sha I
4, there were problems with rounding, which made it difficult to manufacture the inner cutter body J, and the point of consolidation. In other words, Jh@turning blade IC, which is a constituent material of the inner cutter body 1, is usually manufactured by machining tool steel for cutlery.
There are problems with 5, such as not being able to accurately perform Yoai, and 9.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a rotary type shaper that has excellent round performance, is easy to manufacture, and is inexpensive.

[Summary of the incident]

The present invention integrates the spiral blade and the support that constitute the inner cutter body, and forms the cutting edge portion from a material that has been polished with a thermally sprayed coating layer made of a material that has high hardness and wear resistance. The body can be manufactured easily and inexpensively,
! The main points of this project are to enable the practical application of -Tari-type sheathing.

[Embodiments of the invention]

Examples of the present invention are shown in FIGS. 5 to 7 (Hata) below.

This will be explained with reference to (b). Incidentally, parts similar to those of the shaper shown in FIGS. 1 to 4 described above are designated by reference numbers and their explanations are omitted.

The inner cutter body 3' of the Two-1 type shaper is constituted by an integrated screwdriver 12' made of a high-strength At alloy hollow body and a helical blade 1#'. For example, I
OWC-50NICrAAY f A cutting edge portion 11 is formed by polishing a urethane resin-impregnated coating layer as the main material.

Note that the cutting edge body 3' is manufactured, for example, by the following method. The high-strength At alloy hollow body (in the figure, the spiral blade 1-'
) to make 9, to slip on? -6 Process.

Subsequently, this hollow body was subjected to surface degreasing, alumina dal, and sand blast treatment with P, and then thermal spraying distance of 9
SOWC-5 under the conditions of 0 ■, current value 750 A, arc gas r1 thermal spray powder speed 200 to 300 m7's・C
G N1CrAAYO gold powder was sprayed onto the cutting edge forming portion of the hollow body to form a 50 WC-50N bird C with a thickness of 150 μm.
Form an rAAY coating layer.

Subsequently, the hollow body is cooled to a temperature below the aging treatment temperature, and a urethane resin is vacuum impregnated into the coating layer to form a resin-impregnated coating layer (FIG. 7(a)). Next, this coating layer 1#
A part of the hollow body (helical blade 16') is cut, and the surface of the coating layer 19 is polished to form a sharp cutting edge portion II, thereby producing an inner blade in which the drum and the spiral blade are integrated.

The operation of the rotary type shaper of the present invention is the same as described above, but the inner blade body 3' is made of a light alloy and the cutting edge part 18 is made of resin-impregnated 50WC.
-! The coating layer of $0 set Cv Muzy is processed and polished to form a unique round shape.Like conventional products, it has excellent sharpness and low noise, as well as wear resistance, durability, and low power consumption. have sex. If the blade edge part 18 is formed using a urethane resin-impregnated coating layer beforehand, the strength of the blade edge part 1# will be high and will not be easily damaged, and the texture during shearing will be improved due to the action of the slippery impregnated resin. can. Furthermore, in manufacturing the inner cutter body 3' of a single shaper, unlike the conventional assembly process, the assembly process is not necessary, and the rounding and manufacturing costs can be significantly reduced by integral processing of mold casting, thermal spraying, and polishing.

Note that the base material of the inner blade body is not limited to the M-L alloy as in the above embodiments, but also Mt, Mg, Ti, M-L alloy, T
i Gold alloy, any lightweight metal, or thin-walled iron alloy, or
Polymer resins, phenolic resins, other resins, resins, etc. may also be used.

WC-N1C is a material with high hardness and wear resistance that is thermally sprayed.
rAtYK @zu, Mut201t TlO2, etc., etc. may be used.

In the above example, the cutting edge is formed by polishing the resin-impregnated coating layer, but even if the cutting edge is formed by using a coating layer that is not impregnated with resin, the sharpness, abrasion resistance, etc. do not substantially change, and the cutting edge is not sufficiently usable. Endure.

〔Effect of the invention〕

As detailed above, according to the present invention, sharpness, low noise,
We provide fully practical scissors that have excellent performance such as wear resistance, are easy to manufacture, and can achieve lower power consumption by using light metal as the base material for the inner blade. can.
