The present invention relates to a sheath storage type gum which can be carried with permission from the government, and more particularly, to the original texture generated when forging quenching on the leaf of the gum. The present invention relates to a gum gum and a method of manufacturing the same, which form a texture on a foliate to minimize the corrosion and scratches while forming it as it is.

In the conventional medical examination, as shown in Figs. 1A to 4, the tip 20b, the blade 20c, the blade 20d, and the blade 20e are formed on the sword 20a, and the sword 20a. At one end of the sack portion 24, the sack portion 26 is fitted, and the sack portion 24 and the sack portion 26 are supported by the nails 28 crossing the central side of the sack portion 26. It is fixed to prevent mutual flow and departure.

At this time, the hosin 20a is polished with a surface such that the knife width W and the knife thickness T gradually become narrower from the central axis portion L1 to the lattice portion L2. By the processing (칼 布 紙 加工), the center of gravity of the knife is produced differently.

That is, the blade tip portion 20b, the blade portion 20c, the blade portion 20d, and the leaf portion 20e of the dosin 20a have a central shaft portion L1 during rolling or extrusion processing of metal. ) And the knife width (W) and the knife thickness (T) as the knife width (W) and the knife thickness (T) of the lattice part (L2) are all the same from the central axis part (L1) to the lattice part (L2) during polishing paper processing. The center of gravity is prepared differently so that is gradually narrowed.

In addition, since these gum swords are expensive and can be collected by kendo lovers, they must be fully utilized to take full advantage of the physical properties (strength, toughness, elastic modulus, etc.) of the gum sword. Is given value.

However, the conventional gum gum configured as described above is rolled to prepare the knife width W and the knife thickness T gradually tapering from the central axis portion L1 of the rolled or extruded cut 20a to the lattice portion L2. Since the polishing surface is polished after polishing the surface of (20a), the original texture formed on the surface of the leaf portion 20e during rolling or extrusion cannot be maintained as it is, and thus the physical material of the real gum material Not only can the properties (strength, toughness, elastic modulus, etc.) not be fully utilized, but there is a problem in that corrosion and scratches are generated to deteriorate the value as a medical examination.

Therefore, the present invention has been made to solve the above problems, the object of the present invention is to make full use of the physical properties (strength, toughness, elastic modulus, etc.) of the gum gum by keeping the original texture of the carbon steel in the leaf fan as it is To minimize the corrosion and scratches to increase the value as a real gum to provide a real gum formed texture and a method of manufacturing the same.

In order to achieve the above object, the gum sword formed with the texture of the present invention has a blade tip, a blade portion, a blade portion, a blade portion, and a blade portion having a blade portion, wherein the blade portion corresponds to a blade tip portion, a blade portion, a knife back portion, and the like. When polishing a portion, a portion corresponding to the leaf portion is characterized in that the original textured surface is not polished as it is.

In addition, the leaf member is characterized in that the original textured surface was formed by the process of processing so that the knife width and knife thickness gradually narrowed toward the lattice portion from the central axis of the drawing when the forging is quenched by rolling or extrusion.

In addition, the original textured surface of the leaf portion is characterized in that it is formed in an irregular embossed shape by the physical force to apply several hits when forged quenching.

In addition, the method of manufacturing a gum gum texture formed in the foliar of the present invention comprises the steps of rolling or extruding carbon steel in a predetermined length, width and thickness, and forging and quenching the rolled or extruded carbon steel in the central shaft portion Step to process the knife width and knife thickness gradually narrowed toward the lattice part, and the first polished only by the rest of the knife end, the blade, the back of the blade while leaving the original textured surface formed in the leaf portion during the forging quenching And secondary polishing the first polished knife edge, the blade portion, and the knife back portion by abrasive stones, and the second polished knife edge, the blade portion, and the knife portion are a mixture of oil and pure water or pure water. Any one selected from among the steps of heat treatment at a high temperature for several seconds, and the heat-treated knife tip, blade, knife back only the micro sharpener or yarn Polishing with any one selected from the fabric, characterized in that consisting of the step of assembling the bag on the umbe of the dosin.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 5 and 6, the gum gum having a texture formed on the foliar according to the present invention has a blade tip portion 40a, a blade portion 40b, and a blade back portion with respect to the rolled or extruded metal rope 40. When polishing the portion corresponding to 40c), the portion corresponding to the leaf portion 40d is configured to form the original textured surface 40e which is not polished as it is.

That is, the blade portion 40d is processed so that the knife width (W) and the knife thickness (T) gradually become narrower from the central shaft portion (L1) to the lattice portion (L2) of the dosin 40 when rolled or extruded and quenched. By the process of the original texture surface 40e is formed.

In addition, the original textured surface 40e of the leaf portion 40d is formed in an irregular embossed shape by a physical force that strikes several times when forged quenching.

At this time, the material of the dosin 40 is preferably used, for example, carbon steel.

As a result of the present invention configured as described above, the gum gum having a textured texture was forged to be quenched so that the knife width W and the knife thickness T gradually became narrower from the central axis portion L1 of the dosin 40 to the lattice portion L2. When the original textured surface 40e is formed in the leaf portion 40d, and the leaf portion 40d is polished after the forging quenching, the blade end portion 40a, the blade portion 40b, and the back portion 40c are polished. Since the original textured surface 40e can be maintained as it is, it is possible to maintain the original textured surface 40e as it is, so that the edge of the blade portion 40d that is not polished from the blade end portion 40a, the blade portion 40b, and the dorsal portion 40c polished by the sword 40 The physical properties (strength, toughness, elastic modulus, etc.) can be increased, and the leaf portion 40d can minimize corrosion and scratch by the original textured surface 40e.

Next, in the method of manufacturing a gum gum having a texture formed on the foliar according to the present invention, as shown in FIG. 7, carbon steel is constantly rolled or extruded (S1) in a predetermined length, width, and thickness, and rolled in step 1. Alternatively, the extruded carbon steel is forged and quenched so that the knife width W and the knife thickness T gradually become narrower from the central shaft portion L1 to the lattice portion L2 of the insulator 40, and then in step 2, When forging quenching, the original textured surface 40e formed on the leaf portion 40d in the insulator 40 is left as it is, and only the remaining knife end portion 40a, the blade portion 40b, and the dorsal portion 40c are first polished by polishing paper processing. Polishing (S3).

Then, in step 3, the first cutting edge 40a, the cutting edge 40b, and the back 40b of the cutting edge 40 are polished by abrasive stones (S4), and then the cutting edge 2 is polished secondary in step 4 40a, the blade portion 40b, the blade portion 40c are heat-treated (S5) for a few seconds at a high temperature with any one selected from a mixture of oil and pure water or pure water.

Further, only the cutting edge portion 40a, the cutting edge portion 40b, and the cutting edge portion 40c heat-treated in step 5 are finely polished by any one selected from micro grindstone or sandpaper, and then polished (S6). The examination is completed by assembling the bag (S7) on the umbebu (not shown).

At this time, since the blade portion 40d of the tuft 40 is not polished, heat treated, and polished when the steps 3 to 6 are processed, the original textured surface 40e formed during the forging quenching in step 2 is maintained as it is. In this way, the physical properties (strength, toughness, elastic modulus, etc.) of the material (carbon steel) of the gum can be sufficiently saved, and the corrosion and scratches can be minimized to increase the value as the gum.

As described above, the gum gum and the manufacturing method of forming a texture on the foliar according to the present invention forged quenched rolled or extruded material (metal) to gradually narrow the knife width and knife thickness from the central axis to the grid portion, While the original texture is preserved on the surface corresponding to the foliar, only the surface corresponding to the tip of the blade, the blade, and the knife is polished, so that the physical properties (strength, toughness, elastic modulus, etc.) of the real gum can be fully utilized. And minimize the scratch has the effect of increasing the value as a medical examination.
