Description
【発明の詳細な説明】 本発明は時計用指針の製造方法に関する。[Detailed description of the invention] The present invention relates to a method of manufacturing a watch hand.
従来の時、分針はハカマ穴と外形状を板材から
プレス抜きし、このプレス抜きされた針体を一本
づつ治具に取り付けてダイヤカツトし、その後、
ダイヤカツトされた針体にメツキ、塗装を施し
時、分針を完成させている。 Conventionally, the minute hand was made by pressing out the hole and outer shape from a plate material, attaching the pressed needle bodies one by one to a jig and cutting them into diamonds.
The hour and minute hands are completed by plating and painting the diamond-cut needle bodies.
このため、プレス抜きされた針体をダイヤカツ

た。 For this reason, it is troublesome to attach the pressed needle body to the diamond cutting jig, and furthermore, since the attachment condition tends to be uneven, deformation and scratches of the needle are likely to occur after surface processing such as diamond cutting. It was difficult to create a stable guideline.
他方、最近、指針を含めた表示機構を薄くしよ
うとする動きがでてきており、風防ガラスと秒針
との間隔、各指針間の間隔、各指針の厚み、時針

短縮することが重要な課題となつている。 On the other hand, recently there has been a movement to make the display mechanism, including the hands, thinner, and the distance between the windshield and the second hand, the distance between each hand, the thickness of each hand, the distance between the hour hand and the dial, and even more. Reducing the thickness of the dial as much as possible has become an important issue.
このような状況の中で、本発明は完成されたも
ので、帯材にハカマ穴のプレス打ち加工を施し、
その後、表面にダイヤカツト、ホーニング等の表
面仕上を施すと共にマスキングを施し、その後指

する。 Under these circumstances, the present invention was completed, and the band material is press-finished with holes.
Thereafter, the surface is subjected to surface finishing such as diamond cutting and honing, and masking is applied, and then press processing is performed to cut out the outline of the pointer.
以下、本発明の実施例を説明する。図は本発明
を工程順に示している。 Examples of the present invention will be described below. The figure shows the invention step by step.

げられている。 First, a brass or copper strip 1 is continuously pressed to form a hole 2 and a pilot hole 3. (Fig. 1) The hole 2 fits into the pointer shaft of the movement, and the accuracy of the hole 2 is the same as that of the conventional one. The pilot hole 3 is used for positioning during post-processing, and is used in conventional continuous press processing. Figure 2 is - of Figure 1.
A line cross section is shown, and the hole 2 is bent downward.
次に、ハカマ穴２を含む帯材１の表面部分にダ
イヤカツト、ホーニング等の表面仕上４を施す。
（第３図）ダイヤカツトは帯材上に行なうので、
帯材が薄くてもビビレが生じなく、加工上の負荷
が軽減される。 Next, a surface finish 4 such as diamond cutting or honing is applied to the surface portion of the strip material 1 including the hole 2.
(Figure 3) Diamond cutting is done on the strip material, so
Even if the strip material is thin, no vibration occurs and the processing load is reduced.

ープ、粘着紙等で行なうことも可能である。 Next, masking is applied to the surface of the strip material 1 that has been subjected to the surface finishing 4. Masking is performed using a clear lacquer (not shown). This masking prevents scratches, dust, etc. from adhering to the finished surface, and prevents dents from being made to the finished surface during the step of cutting out the outer shape of the pointer, which will be described later. Therefore, masking can also be performed with adhesive tape, adhesive paper, etc. in addition to lacquer.

る。 Next, the strip material 1 including the hole 2 is pressed and the outer shape of the needle is cut out. (Figures 4 and 5) Finally, the lacquer on the surface of the pointer is removed with a solvent such as thinner or acetone, and the surface is then coated with a coating such as plating or painting. (6th
Figure) Figure 7 is a cross-sectional view of the completed pointer 5, in which a surface finish 4 is provided on the upper surface of the brass metal material 6.
A coating finish surface 8 is provided on their outer peripheries.

ことができる。 As described above, since the present invention has the above configuration, the pointer can be manufactured stably and easily. Furthermore, since the step of cutting out the outer shape of the pointer is not performed before the surface finishing step, the thickness of the pointer can be made thinner, and the cut surface does not vibrate or become distorted as in the conventional case. In addition, since masking treatment is performed after the surface finishing step, scratches, dust, etc. do not adhere to the finished surface during the process, especially during the outline cutting step using a press, so that the appearance quality and yield can be improved.
