Description
【発明の詳細な説明】 本発明は時計用表示車及びその製造方法に関する。[Detailed description of the invention] The present invention relates to a watch display wheel and a method for manufacturing the same.
本発明は時分秒以外の表示を行う表示車を合成樹脂シー
ト材を原料として印刷及び時には絞り加工を行うことに
より、供給できる様にしたものである。The present invention is capable of supplying a display wheel for displaying other than hours, minutes, and seconds by printing and sometimes drawing processing using a synthetic resin sheet material as a raw material.
従来は第３図に示すように合成樹脂を原料とした射出成
形機による成形加工を行った表示車が一般的であった。Conventionally, as shown in FIG. 3, display wheels were generally manufactured using injection molding machines using synthetic resin as raw material.
しかしながら、上記の様に成形加工を行った表示車では
、第３図に示すように型の合わせ部にハリ１ａが発生し
たり印刷面１ｂの肉が引けてしまったりして品質上及び
印刷性、外観不良等の課題を有していた。そこで本発明
の目的は、ハリが無い高品質で且つ印刷面に引けのない
印刷性が高く外観の良い時計用表示車を供給するように
したものである。However, in display wheels that have been molded as described above, as shown in FIG. , and had problems such as poor appearance. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a clock display wheel that is of high quality, has no firmness, has excellent printability, and has a good appearance.
上記課題を解決するために、本発明においては原料に合

工の為の案内穴抜きを行い、段差を有する表示車には、
後に熱間もしくは冷間絞り加工を型により行い、次加工
で印刷及び外形抜きをして完成体と成る加工方法により
時計用表示車を得た。In order to solve the above problems, in the present invention, a hoop sheet material made of synthetic resin is used as a raw material, and a guide hole is first punched for hoop processing.
A clock display wheel was then obtained by hot or cold drawing using a mold, followed by printing and outline cutting to produce a completed product.
上記のように構成された本発明の表示車は、時計体に組
み込まれれば、輪列を介して回転して表示内容を表示す
ることができる。When the display wheel of the present invention configured as described above is incorporated into a watch body, it can rotate through the wheel train to display display contents.
また、フープシート材より案内穴ぬき、必要に応して絞
り加工、印刷、外形抜きという工程を経て表示車が製造
できる。In addition, display wheels can be manufactured by punching guide holes from the hoop sheet material, drawing if necessary, printing, and cutting out the outline.

る。Embodiments of the present invention will be described below based on the drawings. 1st
The figure is a sectional view showing the processing method of the present invention, in which processing guide holes are formed in a rolled sheet material 2, which is a raw material, by hot or cold drawing using an upper die 3a and a lower die 3b. Pressure drawing is performed to process the step shape, and in a later process, printing and outline cutting are performed to complete the product. FIG. 2 is a plan view on which the display wheel of the present invention is mounted, and the display wheel 1 manufactured by the processing method of the present invention.
This is an example of a movement with a calendar function.
この発明によれば、従来例で課題となっていた表示車の
端部のパリが発生しない為にこれを取付けて高品質の日
付等表示機能付時計を提供できると共に、完成後の表面
状態が美しく、印刷性が優れている為に外観が非常に美
しい日付等表示機能付時計を提供することができる。According to this invention, it is possible to provide a high-quality watch with a date display function by attaching this to avoid the occurrence of cracks at the edges of the display wheel, which was a problem in the conventional example, and the surface condition after completion is It is possible to provide a watch with a date display function that is beautiful and has a very beautiful appearance due to its excellent printing properties.
