Description
【発明の詳細な説明】 Ｃ産業上の利用分野〕 本発明は、５＃計用ケースの製造方法に関する。[Detailed description of the invention] C Industrial application field] The present invention relates to a method of manufacturing a 5# measuring case.
従来時計用ケースは、主に熱間・冷間鍛造か、ダイキャ
ストのいずれかの方法で製造されている。Conventionally, watch cases are mainly manufactured using either hot/cold forging or die casting.
時計用ケースは、デザインの多様化及び防水性能等の機

場合でも同様であり、ケースは時計の構成部品の中で一
部コストの高い部品となっており、時計のタイプにより
ては全製造コストの半分以上を占める場合もある。Watch cases are required to have complex shapes with strict dimensional accuracy due to the diversification of designs and functions such as waterproof performance. Therefore, for example, hot/cold 111]j&)
In the case of construction,! The manufacturing process alone requires a careful process, and then machining such as cutting is performed to achieve dimensional accuracy.Even simple shapes require more than 20 processes to complete, while complex shapes require a sword process. There are some that exceed. The same is true for die-casting; the case is one of the most expensive components of a watch, and depending on the type of watch, it can account for more than half of the total manufacturing cost.
本発明は上記欠点全除去する為、従来とはまったく異な
る新ｆＡ造方法により製造工程を簡素化し、ケースの製
造コストの低減化を目的としたものである。In order to eliminate all of the above-mentioned drawbacks, the present invention aims to simplify the manufacturing process by using a new fA manufacturing method that is completely different from the conventional method, and to reduce the manufacturing cost of the case.
上記問題点を解決するために、本発明は超塑性材料特有
の優れた圧接性を利用して、超星性合金粉末を温間圧縮
成形する事によって、複雑形状をした時計用ケースを１
工程で製造出来るよう圧した。In order to solve the above-mentioned problems, the present invention takes advantage of the excellent pressure welding properties unique to superplastic materials and warm compression molds superstellar alloy powder, thereby creating a watch case with a complicated shape.
Pressure was applied so that it could be manufactured in a process.
はぼ同じ程度の二相・等軸組縁の微細結粒を持り九Ｚ
ｎ −２２Ａ Ａ合金は温度２８０℃〜２９０℃の範囲
で超塑性現象を起こし、固体拡散が生じやすくなる為、
非常に圧接性に優れた状態になる。It has the same degree of two-phase, equiaxed fine grains and 9Z.
n-22A A alloy causes a superplastic phenomenon in the temperature range of 280°C to 290°C, and solid diffusion tends to occur.
It becomes a state with very excellent pressure welding properties.
そこで、複雑形状をしたケースの粉末成形金型に、上記
答金粉末を充填し、金型を上記温度範囲に加熱した状態
で加圧成形する事により、合金粉末間に固体拡散接合が
生じ、ケースの粉末成形体を得る事が出来る。合金粉末
ＩＣＦｉ、３００℃〜３８０℃加熱後微細化処理を施し

な場合には、と九に重量比にて、０．５％以下のＣＵ、
０．０２％以下のＭｇの添加が有効である。しかし上
限を越えると材料にぜい性が現われ逆効果となる。Therefore, by filling a powder molding mold for a case with a complex shape with the above-mentioned ingot powder, and pressing the mold while heating it to the above-mentioned temperature range, solid diffusion bonding occurs between the alloy powders. A powder compact of the case can be obtained. An alloy powder ICFi that has been heated to 300° C. to 380° C. and then subjected to a refinement treatment is used. Due to manufacturing constraints, part of the case was made using the method according to the present invention, and the remaining part was made using the conventional method.
Of course, that is also possible. If a material with high strength is required, CU with a weight ratio of 0.5% or less,
Addition of Mg of 0.02% or less is effective. However, if the upper limit is exceeded, the material becomes brittle and has the opposite effect.
