質を管理する上で重要な要素でありコスト高となる要因
の一つとなっていた。In the conventional technology, although the watch winding stem 1 is functionally required to have a high processing accuracy of a micron unit, the bending strength is very weak because the material dimensions are minute dimensions of 1 mm or less. There has been a problem that there is a high risk of bending, deformation, and breaking due to the cutting resistance of the metal saws 8, 9, and 10. Therefore, in order to reduce this risk, it is necessary to lengthen the cutting time from 15 seconds to 20 seconds in order to reduce the cutting resistance. Moreover, there is a problem that the quality inspection takes time and the cost increases. . Further, due to the abrasion of the blade of the metal saw, cutting burrs and cutting surface roughness occur at the corners of the square-shaped portion 4, and the conventional technique has a problem that a step of removing them by barrel processing is required. However, if the metal saw wears out, it will not be possible to remove them in the barrel processing, so even if an expensive metal saw is used, replacement or regeneration processing of the metal saws 8, 9, 10 is performed every time tens of thousands of winding stems are processed. Is necessary, which is an important factor in controlling the quality of the rectangular portion 4 and is one of the factors that increase the cost.

が出来る。In order to achieve the above-mentioned object, in the manufacturing method of the present invention, four independent pieces having a flat and smooth flat surface corresponding to the corner-shaped portion 4 of the timepiece stem 1 are provided around the piece. The rectangular shaped portion 4 is formed at a high speed by crushing by pushing into the timepiece winding stem material 5 with uniform pressure and operating amount. The timepiece material 5 for a timepiece is deformed in the radial direction and the length direction by the action of crushing. However, by setting the material size in consideration of this amount of deformation in advance, the dimensional accuracy after crushing is guaranteed. In addition, in order to stably apply an even pressure and actuation amount to each of the four pieces, a response system using a cylindrical taper is used, and guides are attached to prevent bending of both end portions of the rectangular portion 4 in the length direction. As a result, it is possible to process the high-quality square-shaped portion 4 within a short time, which is far longer than the cutting time by the conventional metal saws 8, 9 and 10. Moreover, the flat surface for crushing of the four pieces can be remarkably improved by lapping and the like, so that the finished surface of the square-shaped portion 4 can be remarkably improved and burrs are not generated, so that barrel processing after the square-shaped processing is unnecessary. became. Furthermore, the four pieces for crushing are made of materials with high wear resistance and high hardness, such as high-speed tool steel and super hard alloy, to obtain durability that enables processing several million times.

来の焼入れ処理の条件でも曲り・変形の発生が無い。In the above-mentioned manufacturing method, a highly malleable metal material is used for the timepiece winding stem 1, and by applying uniform pressure and actuation amount in a plane from four directions, each of the four sides of the square portion 4 is Since a uniform force and elongation are generated, a highly accurate square shape can be processed. The watch winding stem 1 is then subjected to quenching treatment, but the material has high extensibility and little internal strain stress due to crushing, and the crushing force is even on the four sides, and the distribution of the internal strain stress is also on the four sides. Since they are even, there is no bending or deformation even under the conditions of conventional quenching treatment.

FIG. 1 is a side view with a partial cross section showing the structure of an apparatus for carrying out the manufacturing method of the present invention. An inner cylinder (14) having a cylindrical taper shape (13) is slidably inserted into the inner diameter of an outer cylinder (12) fixed to a frame (11). Furthermore, the inner diameter of this inner cylinder 14 is 90
A quarter split collet chuck 15 is slidably inserted, and four crushing pieces 16 and four screws 17 are fixed to this end face. 4 split collet chuck
A taper shape that matches the cylindrical taper shape 13 of the inner cylinder 14 is machined on the outer periphery of the inner cylinder 14. When the inner cylinder 14 is pushed by the operation of the pressurizing cylinder 18, the taper shape responds to this taper shape and four The crushing piece 16 has a structure in which the crushing piece 16 is tightened toward the center with uniform force and actuation amount. The watch winding stem material 5 is crushed and formed at this portion. In order for the crushing piece 16 to be tightened by the operation of the pressure cylinder 18, the quartet collet chuck 15 must be fixed in the operating direction of the pressure cylinder 18. A cap 19 is attached to the cylinder 12 to receive the end face of the quarter collet chuck 15. A compression coil spring 20 is installed inside the inner cylinder 14 so that the inner cylinder 14 can be operated when the pressure cylinder 18 is inactive.
The purpose of pushing back the crushing piece 16 and opening the crushing piece 16 is to press the quartet collet chuck 15 against the cap 19 at all times.
It serves the purpose of keeping the 16 horizontal positions constant.

込みを長くし、揺動支点を長くすることで近似的に平行
な動きとなるようにした。The movement of the crushing piece 16 is rocking with the interruption end of the quartered collet chuck 15 as a fulcrum, but the opening / closing operation amount of the crushing piece 16 for forming the angular portion 4 of the watch winding stem 1 is small. 0.2 mm
Since the following trace amount is sufficient, the interruption of the quarter split collet chuck 15 is lengthened and the swing fulcrum is lengthened so that the movements are approximately parallel.

た。A guide 21 for preventing the tip of the watch stem material 5 from being crushed is fixed to the inner diameter of the four-piece collet chuck 15, and the outer diameter of the tip of the watch stem material 5 is attached to the end face. A guide hole 22 for receiving is provided. When crushed, the watch winding stem material 5 extends in the lengthwise direction, and when restrained, buckling deformation occurs. Therefore, the guide hole 22 has an inner diameter dimension that allows the outer diameter of the tip end of the watch winding stem material 5 to slide. , I gave a margin to the depth.

力以上の延び力を受けた時に逃げる構造となっている。The watch winding stem material 5 held by the clamp 23, which also serves to guide the rear end portion of the watch winding stem material 5, is squeezed by the movement of the movable table 24 into the crushing piece 16 with a specified dimension. Although it is formed, the clamp 23 is slidably held by the holder 25 in order to prevent the time winding stem material 5 from extending in the lengthwise direction at this time, and the clamp force is equal to or greater than the compression force of the compression coil spring 26. It has a structure that escapes when it receives the extension force of.

の圧潰用角穴28を形成することが出来る。FIG. 2 is a front view of the crushing piece 16 in the apparatus shown in FIG. The characteristic of the crushing piece 16 is that its operation is stopped by the side surfaces 27 of adjacent pieces coming into contact with each other, and the fluctuation of the operating amount of the pressurizing cylinder 18 and the inner cylinder 14 or the quart collet chuck 15 are caused. Even if the cylindrical taper shape (13) is evenly worn, the crushing square hole (28) having a stable size can always be formed.

心が僅か太くなり両端が著しく細くなる変形を示す。FIG. 3 is a diagram showing the distribution of deformation of length and outer diameter when the watch stem material 5 having a uniform circular cross-section is crushed by the apparatus of FIG. Since many plastic deformations due to crushing appear on the space side, the length extends a lot at both ends, and the outer diameter shows a deformation in which the center is slightly thicker and both ends are significantly thinner.

で細く中心へ向うと太くなるような変形の分布を示す。FIG. 4 is a diagram showing the distribution of the deformation of the length and the outer diameter when the watch stem material 5 having the hourglass shape applied in this embodiment is crushed. Due to the drum shape, a space 29 exists when the crushing piece 16 and the watch winding stem material 5 are in contact with each other, and deformation due to crushing also occurs in the direction of eliminating the space 29. Therefore, the deformation of the length is particularly large at both ends of the material, and the outer diameter exhibits a distribution of deformation in which both ends are thin and become thicker toward the center.

で、圧潰後の角形状部分４を従来の形状と同等にした。FIG. 5 is a view comparing the shapes of the square-shaped portions 4 when the above-mentioned two kinds of watch stem materials 5 are crushed and formed, and is shown so as to be compared with the conventional watch stem 1. FIG. 5 (a) shows a winding stem according to the prior art, in which the square-shaped portion 4 has a constant length L and a uniform cross-sectional shape of opposite sides X, diagonal Y, and face width Z.
Made of. FIG. 2B shows a timepiece stem material 5 having a uniform circular cross-sectional shape and a shape when the material is crushed. The crushed angular portion 4 has a longer length than the conventional one, and the cross section of each portion is also non-uniform. In particular, the fact that the surface widths Z 1 and Z 3 are significantly smaller than those of the conventional ones causes problems in terms of reduction in rotation transmission efficiency and durability. FIG. 5 (c) shows a material having a drum shape which is further improved in this embodiment, and a shape when the material is crushed. By shortening the material length and making it more hourglass-shaped, the square-shaped portion 4 after crushing has the same shape as the conventional shape.
一例として本実施例において適用した素材寸法の具体例
を第６図に示す。As an example, FIG. 6 shows a specific example of material dimensions applied in this embodiment.

以上の説明で明らかなように、本発明は下記のような効
果がある。As is clear from the above description, the present invention has the following effects.
従来行っていたメタルソー８、９、10での削成と異な
り、切削抵抗が及す曲り・変形・折れへの影響が無いた
め、加工された精度が向上し品質が安定する。Unlike conventional cutting with metal saws 8, 9 and 10, there is no effect on bending, deformation and bending caused by cutting resistance, so the precision of processing is improved and the quality is stable.
圧潰による加工であるため、従来のような切削バリ及び
削成面荒れがなく加工面が綺麗なため、加工後のバレル
処理が不要となる。Since the processing is performed by crushing, there is no cutting burr and roughening of the surface to be machined as in the conventional case, and the machined surface is beautiful, so that barrel processing after processing is unnecessary.
圧潰が角形状部分４の４方向で同時に且つ瞬時に（例え
ば１〜２秒）行われるために、加工時間を従来の削成方
式より飛躍的に短縮させることが出来、生産性の向上に
つながる。Since the crushing is performed simultaneously and instantaneously (for example, 1 to 2 seconds) in the four directions of the rectangular portion 4, the processing time can be dramatically shortened as compared with the conventional cutting method, which leads to improvement in productivity. .
圧潰用駒16が受ける力が主として面圧力のために、工具
寿命が向上し、巻真単価に占める工具消耗量を大幅に削
減することができる。Since the force received by the crushing piece 16 is mainly the surface pressure, the tool life is improved and the amount of tool wear in the winding stem unit price can be greatly reduced.
上記のような効果により、高精度・高品質・高速、且つ
低コストで時計用巻真１の角形状部分４の加工を行うこ

ことが出来る。Due to the above effects, it is possible to process the square portion 4 of the watch stem 1 with high accuracy, high quality, high speed, and low cost. The timepiece winding stem material 5 having the hourglass shape applied in this embodiment can be easily manufactured by a conventional automatic lathe.
又、従来技術の方法では、角形状部分４を削成する加工

る。Further, in the method of the prior art, since the processing time for cutting the rectangular portion 4 is long, a large-scale processing device different from the automatic lathe for producing the watch winding stem material 5 is used for the purpose of improving productivity. I needed it. However, since the manufacturing method by crushing of the present invention is high-speed and the structure of the device is simple and can be miniaturized, by attaching this to a conventional automatic lathe, the cycle time of the automatic lathe is not significantly lengthened, and The integrated processing of the shape part 4 can be performed only by an automatic lathe.
