Description of the Invention: [Technical Field] The present invention relates to a method for manufacturing a comb body for thinning shearing and an improvement of a thinning shear, and more particularly to a sintering method for sintering a shaped body The method of manufacturing the comb body and the thinning shear. [Prior Art] Although the moxibustion and hairdressing scissors are made up of two blades, the thinning scissors of this kind of scissors are shown in Figure 1Θ, which is the comb body 3G1 and the bar of the knife body. The body 3〇2 is assembled. The comb body 3〇ι, system, 軚刀# 3〇3 is set up by the comb knife #3〇4, whereby the hair can be thinned. There is also a thinning shear that does not use a bar body 3〇2, and two comb bodies are assembled to each other. The king examines the hurricane, the lipstick, and the valley scissors. As shown in Fig. 17, the semi-finished knives 401 and the shank 4〇2 are generally fabricated separately, and the two are welded to form the cutter body. 1 Depending on the hard stainless steel material suitable for the tool, the handle 401 does not require hardness. Therefore, unlike the knife portion, it is preferable to use half of the rust resistance. ,'material. The knives are obtained from a stainless steel sheet, forged by a knife portion and a finger ring 40, or by stamping only with a die. Further, the shank portion 4〇2 is formed by the shank 405. However, if the shape of the finger ring 4〇6 is relatively simple, the shape of the finger ring 4〇6 is made by casting. The knives 4〇1 obtained by the semi-finished product are welded to the shank portion 402 to complete the machining of the body of one of the knives from the knives of the knives as shown in Fig. 16. The semi-finished product, the cutting comb slot 3〇4 forms a comb knife #3〇3, and is formed as a comb body 30 〇. • As for the cutting method, if the comb teeth are linear as shown in the illustrated comb teeth 303, the comb grooves are cut one by one using a disc-shaped grinding machine. In addition, as shown in Fig. 18, the thinning shear 500 is also a case where the comb teeth 5〇3 are arc-shaped. In the case of such an arc shape, since it cannot be cut by a disc-shaped grinding machine, the lure-line type is used. The electric discharge machining cuts the comb knives 5〇4 & _, thereby forming the comb teeth 503. Recently, the thinning shears, such as the ones in which the comb teeth are arc-shaped, are the mainstream. However, it takes a long time to process, and it takes about 3 hours to cut all the comb squeegees of the ram comb body. Therefore, it is necessary to operate the fully automatic production line for 24 hours. As described above, the process of making the semi-finished product of the comb body and the process of cutting the comb and the back of the semi-finished product are also one of the important processes. In other words, in general, the blade portion of the hairdressing and beauty scissors has a cross-sectional shape φ as shown in Fig. 19, and is ground in an arc shape at the edge of the blade 3〇〇B, and is ground in the blade back 300°. The shape of the back gap 31 5 (micro recess) is formed. The backlash 3 j 5 is used to make the edges of the blades in contact with each other, that is, if there is no such backlash 31 5 , the blades are in contact with each other to cause a gap between the edges, so that the hair cannot be cut, but if there is such a back gap, As shown in Fig. 20, the blades are not in contact with each other, and the blades are sure to be in contact with each other. In addition, if the plate is cut by a grinding machine or a wire electric discharge machining, the circumference of the cut comb groove is formed at a right angle, so that the comb teeth have a square shape with a corner angle of four corners. However, if the peripheral edge of the comb sipe is angled, 1276518, when the hair entering the comb sipe is detached from the comb sipe, the hair is rubbed over the peripheral corner portion, thereby causing defects in which the hair is not easily detached. λ also has defects in hair that are rubbed through the corners and damaged. Therefore, it has been proposed to thin the corners of the corners (see Patent Document 1). (Patent Document 1) Japanese Laid-Open Patent Publication No. 2003-290572 (the content of the invention) Some methods to grind the surface are quite troublesome. In particular, if the comb teeth are arc-shaped, the chamfering of the comb teeth is more troublesome. Further, by the method of forging or the like, the shape of the blade is formed by stamping with a die, and the edge or the backing process is added, and the period from the 35 process to the finished product is as short as possible. In particular, thinning shears are expected to shorten the forming process of the comb pockets. In view of the above problems, the present invention provides that the thinning of the thinning shear can be shortened, and the periphery of the comb sipe is a rounded arc. Even if the back of the knife is ground, the backlash does not eliminate the thinning comb of the slit. The method of making a body and its thinning shears. In order to solve the above problems, the first invention of the present invention is a method of manufacturing a comb body for thinning shears. In addition, the comb system is replaced by a comb tooth and a comb slot. The manufacturing method is characterized in that first, a molded body corresponding to a comb body blade portion is formed, the molding system having a remaining portion in which the tooth tips constituting the comb tooth portion are connected to each other, and the remaining portion is other than A molded body having a shape substantially the same as that of the comb body is formed in part. The shaped body is then sintered to form a sintered body, and the remaining portion 1276518 is removed from the sintered body to form the front end of the comb tooth. In the method forming system, "the portion other than the remaining portion is formed into substantially the same shape as the comb body". Here, since the shape of the comb tooth (the 锁, or the ejector pin for releasing the mold from the mold) is left in the molded body, the shape of the comb tooth is not the same as the shape of the comb tooth. "Shape" is indicated. By this, it is known that the comb body manufactured by many steps can be manufactured in a relatively small number of processes. Specifically, for example, if it is a forging manufacturing method, it is necessary to pass through many processes such as die-cutting from die-cutting, blade-back grinding, comb-tooth cutting, and the like, but it is sufficient in accordance with the present invention to reduce the number of processes. In particular, since the comb groove is formed at the same time as the forming, the conventional cutting operation can be reduced, so that the cutting operation can be reduced (the most time-consuming in the manufacturing time of the comb body, for example, it takes 3 hours for the boring body 1). Reduce manufacturing time. Further, the sintered body can be formed into a finished product by applying only a slight surface treatment, which also shortens the manufacturing time. Since the same shape can be mass-produced, the specifications of the mass-produced product can be easily and correctly maintained. Also in this manufacturing method, the shape of the front end of the comb tooth can be formed by selecting the shape of the remaining portion to be removed. Thereby, it is possible to easily change the front end of the comb tooth to a different type of comb body from the sintered body of the crucible type. Further, in this manufacturing method, the molded body may be formed into a shape in which the peripheral edge of the comb groove is deviated. By forming, once the mold is prepared, it is easy to make the circumference of the comb groove 1276518 into a shape of a chamfer. If it is conventionally known, it is necessary to cut and remove the corners of the comb groove, but the forming is not This kind of work is required, and even if the correct angle is formed, even if the circumference of the comb groove is formed into such a shape, the two ports are formed into a completed shape, and only the grinding of the degree of m is applied. Maintain the shape of the peripheral chamfer of the comb slot. In other words, if the shape of the formed blade needs to be further polished, the tooth is removed by grinding, so that the surface formed by the forming (ie, the angle) is eliminated. However, since the surface formed by molding and sintering is very close to the finished product, surface processing such as polishing is not required at the time of production, whereby the shape of the formed chamfer can be maintained as it is. Further, in the manufacturing method, the formed body may be formed in a strip-shaped concave portion extending from the base end of the molded body toward the distal end in the center of the back width of the molded body as (4) 'step-step non-recessed portion on the back of the blade Both sides of the width are used to ejector with the ejector pin. Thereby, the conventional process of forming a back gap grinding or the like can be omitted. Moreover, it is only necessary to perform the work of removing the pin marks of the ejector pin of the blade back, but if it is polished with a flat abrasive material, the person who grinds is only on both sides of the width of the not-recessed blade back (peak edge and knife edge) Side), the recess will not be ground. That is, the comb teeth that are chamfered and have a circular arc shape will not be ground. Therefore, the shape of the chamfer can be maintained. That is, if the comb teeth need to be polished, the shape of the chamfer obtained by the forming is also formed into an angular shape by grinding, but the concave portion of the back is not only the backlash 'i but also has the state of maintaining the comb teeth so chamfered. Two functions. In the second invention of the present invention, a thin shear is disclosed. The thinning shear is made by using the comb body obtained by the above manufacturing method 1276518. Thereby, the mold shape can be transferred to mass-produce the same shape, and the shape accuracy can be obtained. Therefore, in the case of conventional forging, the surface shape of the knife edge or the back of the blade needs to be precisely ground, but the present invention, by forming and sintering, is conventionally obtained from the beginning of the final process, and is sintered at the beginning. At that time, you can get it. In particular, in the molded article of the present invention, since the comb teeth are connected by the remaining portion, it is possible to suppress deformation of the elongated comb teeth by sintering, and the sintered molded body originally has high precision, and otherwise Plus, you can get higher precision. For example, Ding thin shears, comb teeth between each other, formed into a population of hair into the comb sipe, if the comb teeth are slightly _ curved, then the person D in the comb sipe will produce uneven size Difference, but this thinning shear will not

Here, the thinning shears are preferably made into a shape in which the molded body is formed into a peripheral corner of the comb groove. Therefore, the 瓸 Μ ^ will not get stuck in the comb squeegee, so that the comb from the comb; "smoothly detached. Sintered into the surface of the sintered body due to the fineness: two bodies, even if no processing is applied to the comb squeegee, comb The tooth is affected: the face is still, so the point will not be stuck, so the hair will not be thinned here. In order to maintain the scissors' at the stage of the forming body, the concave-like grinding as the backlash is set. The back of the knife, but in this case, the backlash 1276518 disappears. Therefore, it is necessary to re-grind the back of the knife to re-form the backlash. However, the thinning shear of the present invention is formed by preliminarily forming the back gap as a concave portion, even if the grinding knife is old. This kind of depth can be avoided by a certain depth of the concave portion. Even if the back of the blade is polished, the surface of the comb groove is not reduced by the concave portion, and the thinning is performed as described above. The manufacturing method of the comb body for cutting can shorten the manufacturing process of the comb body, and as a result, the process of thinning shear can be shortened, and the comb body of the circular arc of the comb groove can be easily realized and used. Thinning shears. Moreover, the precision is high due to thinning shears. The comb sipe can also obtain a thinning shear that removes the good hair from the surface. If the knives do not cause the backlash to disappear, the surface of the comb squeegee will not disappear. [Embodiment] Next, an embodiment of the present invention will be described. Further, the manufacturing method of the comb body is performed together with the description of the thinning shear using the comb body. The thinning shear 1 of this embodiment is as shown in Fig. 1. As shown, the comb body 100 is assembled with the bar body 200. The comb body 1 has a blade portion 1〇1 and a handle portion 1〇2, and the blade portion 101 is separated by a comb knife as shown in FIG. The comb 104 is provided with comb teeth 1〇3. The comb body 100 is similar to the figure 7 shown in the description of the prior art, and the semi-finished products of the blade portion 1〇1 and the handle portion 1〇2 are respectively formed. The welder is welded and joined to make a semi-finished product of the comb body, and thereafter the comb body is completed by various processes, thereby combing the cutter body 100 and the bar cutter body 200 to obtain a thinning shear. The comb body of the comb body 1 0 0丨0丨, the sintered body corresponding to the blade portion is formed by MIM molding. 11 1276518 First, a mold (not shown) is prepared, and it is formed as shown in FIG. The molded body 1 10, as shown in FIG. 4, is obtained by kneading (S1) and granulating a stainless steel metal powder as a scissor material and granulating to obtain a composite, thereby melting the composite. The post-molding is formed in the mold (S2). The mold is composed of a knife-side mold and a back-side mold of the comb body, and the page output pin is disposed on the knife side cooker. The pin of the ejector pin remains on the back of the knife. The shape of the y-body 11 is formed to have substantially the same shape as the blade portion 101 of the final comb body 100, and the screw hole 112 is formed. However, the knife edge side thereof will become the portion 236 of the comb tooth. The remaining portion 1U of the tooth tip extension is formed such that the shape of the comb teeth 113 is connected to each other (see FIG. 5 and the remainder of the remaining portion (1), and is formed to be substantially the same shape as the comb body when completed. body. Therefore, the shape of the remaining portion (1) is provided, which is different from the comb body 1〇〇 of the finished product, and the remaining portions ^ are joined along the knife edge line, thereby forming a state in which the adjacent combs #113 are supported by each other. Further, as shown in Figs. 6 and 7, the blade back 11A of the molded body 110 is formed in a strip shape extending from the base end X of the molded body 11 toward the front end Y in the center of the width of the blade back 110A of the molded body 11 The recess J丨5 serves as a backlash. The back of the non-recessed portion 115 is the Ml6a, U6b (ie, the peak side and the knife edge side) as the ejector pin. Further, in the molded body 110, as shown in Fig. 8, the peripheral edge of the comb sipe 114 is chamfered so that the comb teeth 113 are formed such that the knife edge side i 丨〇 B and the blade back side 丨 1 均 both have a circular arc shape. The molded body 110 thus formed is sintered by a predetermined method (S 12 of No. 12 1276518, FIG. 4), and then the sintered body is demolded, whereby a sintered body as shown in FIGS. 3 and 6 can be obtained, and the sintered body and the comb are provided. The blade portion 1〇1 of the body 1 has almost the same shape and differs only in the blade portion having the remaining portion 111. Since the sintered body has a small shrinkage rate upon sintering, it has the same shape as the molded body before sintering. Further, the sintered body is also almost in the same shape as the comb body of the final product, and the surface of the knife edge is formed to be close to the beautiful state of the finished product. Further, since the comb teeth are elongated, they are easily deformed during sintering, and if they are deformed, a width difference is generated at the entrance of the comb groove, and defects are likely to occur. However, since the comb teeth are largely connected by the remaining portions, the comb teeth are supported by each other, whereby the effect of preventing deformation of the comb teeth during sintering can be obtained, and comb teeth having high dimensional accuracy without deformation can be obtained. Further, in the back of the sintered body, the concave portion is still formed in the same shape as the finished product and the surface is also close to completion. However, at the places 116a, 116b, etc. outside the recess of the blade, the pin 117 of the ejector pin is retained, which is different from the finished product. Further, on the peak side, there is a nozzle mark 118 when it is emitted. In this state, the separately prepared shank (not shown) is welded to the sintered body to temporarily complete the semi-finished product of the comb body (symbol S4 of Fig. 4). Then, the nozzle mark 118 is removed from the blade portion by grinding, and the blade back 110A is again ground with a plane grinding material to remove the pin mark 117. Even in this case, the back side 11 〇 a of the comb tooth 113 or the comb groove 114 is not brought into contact with the abrasive material by the recess 115, so that the arc of the circumference of the comb groove 114 is not polished. Further, as shown in Fig. 9, from the sintered body 12 of the sintered blade portion, the remaining portion 121 is removed to form the front end 123a of the comb tooth 123. By wire sawing electrical discharge machining, the broken line of Fig. 9 is used as the cutting line for cutting, whereby the comb tooth (1) 13 1276518 1 Ο 0 comb tooth 1 〇 3 is formed in the shape of the front end of Fig. 1 . Then, the surface is formed next to this state, and the comb body 1 is substantially completed. The soft abrasive cloth for polishing is finished as the surface of the blade portion 101 or the handle is finished, and the comb body 1 is finished. Thereafter, it is assembled with another bar body, and the kneading state is adjusted. Finally, the blade body is ground to complete the blade. Further, the above processes may be replaced as needed, and are not limited to the above order. Further, the shape of the comb teeth or the shape of the tip end thereof can be freely changed. Alternatively, the two comb bodies can be assembled to form a thinning shear without using a rod body. Further, even if the same sintered body is used, by selecting the shape of the remaining portion, it is possible to form the front end shape u of various comb teeth, and to provide two concave portions 123b at the front end of the comb body 123, and to cut off the remaining portion by electric discharge machining. At 121 o'clock, the wire saw can be cut along the shape of the knife edge. Further, in Fig. 12, the remaining portion 121 is located between the comb teeth 123 and the comb teeth 123 to connect the comb teeth 123, but the connecting portion is cut to form a straight knife. And set in the center of the straight knife! A narrow recess 123c. Further, even if the thinning shear of the same molded body is used, when the remaining portion is to be cut, as shown in Figs. 13 to 15, the width of the mouth portion 125 of the comb groove 124 is still selectable.
