Abstract
Description
【発明の詳細な説明】 本発明は時計側の製造方法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing a timepiece.
時計側は一般には、第1図、第2図、第3図開示す様に
、胴1に上胴2、側バイブロ、バイト接続足4、装飾用
かざり5、バンド先駆6等の外装部品が接続される構造
が取られる。As shown in FIGS. 1, 2, and 3, the watch generally includes exterior parts such as a body 1, an upper body 2, a side vibro, a bite connection foot 4, a decorative ornament 5, and a band tip 6. A connected structure is taken.
時計側を構成する前記外装部品を接合する方法としては
、従来有機接着剤を用いる方法、喰い付きを利用する方
法、ロウ付けする方法等が採用されている。有機接着剤
を用いる方法では接着作業に熟練度と加工時間を多く要
する欠点があるばかりで無く、経時変化による劣化を免
かれることが難しく満足できる接合方法とは言い難い。Conventional methods for joining the exterior parts that make up the watch side include a method using an organic adhesive, a method using bite, a method using brazing, and the like. Methods using organic adhesives not only have the disadvantage that the bonding work requires a high degree of skill and processing time, but also cannot be said to be a satisfactory bonding method because it is difficult to avoid deterioration due to changes over time.
喰い付きを利用する方法は、喰い付きのための部品相互
の寸法精度、形状管理が厳しく、部品製作上回難度が大
きい。又、合成樹脂より成る部品を介して喰い付ける方
法では、該部品を入れるスペースも必要であり、時計側
の細線化、薄型化に対してデザインが制約される欠点が
ある。The method of using biting requires strict dimensional accuracy and shape control between parts for biting, and is highly difficult to manufacture parts. In addition, the method of attaching the watch through parts made of synthetic resin requires a space to accommodate the parts, and has the disadvantage that the design is restricted when the watch side is made thinner and thinner.
他の方法としてのロウ付は方法は、ロウ材を使用し、高

面品質の劣化が起こることから時計側のデザインが制約
されたり、修正工程が避けられない欠点がある。Another method, brazing, uses brazing metal and is complicated to braze in a high-temperature furnace, which not only causes high costs, but also exposes the watch side to high temperatures. Recrystallization or brazing of metals causes oxidation due to the atmosphere in the furnace, and furthermore, the solder metal flows out, resulting in deterioration of the quality of the finished surface, which limits the design of the watch and has the disadvantage that correction processes are unavoidable. .
本発明の目的は胴に時計側を構成する外装部品を接合す
るに際し、′従来の欠点を解消することである。An object of the present invention is to eliminate the conventional drawbacks when joining exterior parts constituting the watch side to the case.
本発明は時計側を構成する金属製の外装部品のうち少l
、【くとも一つに突起部を設け、抵抗溶接により、上記
部品を接合することを特徴とするものであり、該外装部
品は少なくとも一つが時効硬化合金であることによって
、さらに大きな効果が得らハ、ろ時計側の製造方法であ
る。The present invention focuses on a small portion of the metal exterior parts constituting the watch side.
[It is characterized by providing a protrusion on at least one of the parts and joining the above parts by resistance welding, and when at least one of the exterior parts is made of an age hardening alloy, an even greater effect can be obtained. This is the manufacturing method of the watch.
本発明てよる抵抗溶接は、接着剤、ロウ材等の介在物は
全く用いず作業は単純化されるため作業刊、良い。Resistance welding according to the present invention does not require any inclusions such as adhesives or brazing metals, and the work is simple, so it is very convenient.
さらに被接合物は、全体が高温にさらされろことなく、
突起部及びその極めて周辺のみ高温に加熱されろため、
従来例で述べたロウ伺は時の欠点は皆無である。Furthermore, the objects to be joined are not exposed to high temperatures as a whole.
Because only the protrusion and its surroundings are heated to a high temperature,
The rowing method described in the conventional example has no disadvantages at all.
さらて、時効硬化合金型の金属材料からなる時計外装部
品を用いれば、接合に対して特に有利となり面l傷外力
優れた時計側を得ることができる。Furthermore, if a watch exterior part made of an age-hardening alloy type metal material is used, it is particularly advantageous for joining, and a watch side with excellent surface scratch resistance can be obtained.
すなわち、時効硬化し、た時計外装部品が軟化しない温

おり、軟化する部分Qま極めて限られた溶接点のみてあ
り、接合は容易である。In other words, it is difficult to establish a method for soldering at a temperature that does not soften age-hardened watch exterior parts, but in the resistance welding of the present invention, the parts are heated to high temperatures. The parts are extremely limited.
Also, as a watch exterior part, it maintains the hardness of 1-year hardness, and there are only very limited welding points including the softened part Q, making it easy to join.

明の製造方法を採用することて゛硬さを低下することな
く接合が可能なブこめ、より有効な製造方法であること
が明ら力・て・ある。In recent years, in order to maintain the appearance of excellent initial polishing quality over a long period of time, hard materials with excellent scratch resistance have been increasingly used for watches. The method of joining these hard materials requires the expansion of the tesine and the functionality, but by adopting the manufacturing method of the present invention, it is possible to join without reducing the hardness. It is clear that this is an effective manufacturing method.
次に本発明を実施例に依って説明する。Next, the present invention will be explained based on examples.

At point P inside the upper shell, which is 0.10 ma away from the joint surface in the cross section of the weld between shell 7 and upper shell 8, the HV decreased to 580, and the structure had changed, but at a point 0.13 rua or more away from the joint surface. teeth,
There was no change in structure or decrease in hardness, and there was no effect on the watch side.
〈実施例2〉

When resistance welding was performed through the protrusion 10a with a pressure of 15 kgf, uniform welding was achieved over the entire circumference of the end face of the side pipe, and a waterproof seal was maintained. The fixing strength is also 45 to 9 with tensile force.
It was sufficient as the fixing strength of the dovetail side pipe.
実施例2に示す胴と側パイプの接合を従来の圧入、接着

ため高圧防水信頼性を長期てわたり保証することはでき
ず不利な点が多い。If the shell and side pipes are joined using the conventional method of press-fitting and using an adhesive as shown in Example 2, the following problems arise. In other words, it is necessary to strictly control the body dimensions for press-fitting and the outer diameter dimensions of the side pipes, and not only does adhesive bonding require skill, but the organic adhesive deteriorates over time, making it difficult to rely on high-pressure waterproofing. There are many disadvantages as it cannot guarantee long-term sex.
