Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、高精度を有するピンセットを機械加工によ
り量産し、それだけ低コストで提供出来る金属製ピンセ
ットの製造法に関するものである。Description: TECHNICAL FIELD The present invention relates to a method of manufacturing metal tweezers, which can mass-produce tweezers having high accuracy by machining and provide the tweezers at such a low cost.
ピンセットは、時計、弱電産業のみならず医療分野と
いろいろな方向に使用されている。Tweezers are used not only in the watch and light electric industries but also in the medical field in various directions.
従来のピンセットは第１図に示すように２枚の挾着板
１の接続端部２をスポット、ろうづけ等の溶接若しくは
かしめ等で止着して作る製造法と，図面は省略するが一
枚の帯状板をＵ字状に折り曲げて作る製造法がある。As shown in FIG. 1, the conventional tweezers has a manufacturing method in which connecting ends 2 of two clasping plates 1 are fixed by welding such as spotting, brazing or caulking, and a drawing is omitted. There is a manufacturing method in which a band-shaped plate is bent into a U shape.
前者は溶接する時にどうしても挾着板がずれてしまう
からバラツキが生じて先端の挾着部３が合わなくなり、
精度の高いピンセットを作ることが難しかった。In the former case, when the welding is performed, the holding plate is inevitably displaced, so that there is variation and the holding portion 3 at the tip does not fit,
It was difficult to make tweezers with high precision.
このため、従来では溶接後、一本一本を手加工により
挾着部の精度を出しているが、この手加工も熟練者であ
っても大変な仕事であり、このため量産出来ず、それだ
けコスト高にしている。For this reason, in the past, after welding, the accuracy of the clasped part was obtained by hand-processing each piece, but this hand-working is also a difficult task even for a skilled worker, and therefore mass production is not possible. The cost is high.
また、溶接跡をきれいに仕上処理をしなくてはならな
いから一層手間のかかる製造法であった。Further, since the welding trace must be cleanly finished, the manufacturing method was more troublesome.
後者は、一枚の帯状板をＵ字状に折り曲げるだけであ
るから簡単な反面、前者よりも一層のバラツキが生じて
精密用のピンセットとしては不向きであった。The latter is simple because it bends one strip-shaped plate into a U-shape, but is more unsuitable than the former and is not suitable as precision tweezers.
本発明は、かかる欠点を解決したもので、機械加工に
より精度の高いピンセットを容易に量産し、それだけ低
コストに提供することが出来る金属製ピンセットの製造
法を提供することが技術的な課題である。The present invention has solved the above drawbacks, and it is a technical problem to provide a method for manufacturing metal tweezers that can easily mass-produce high-precision tweezers by machining and provide it at such a low cost. is there.
挾着板10 2枚分の厚みに相当する厚みの板素材ａの中
心を挾着部11に相当する部分から接合端部12に相当する
部分の手前までスリット状に割り込みして２枚の挾着板
10を形成し、この挾着板10を左右に開いてピンセット体
ｂを形成する。Clamping plate 10 The center of a plate material a having a thickness corresponding to the thickness of two sheets is interrupted in a slit shape from the portion corresponding to the clamping portion 11 to the front of the portion corresponding to the joining end portion 12, and the two clamping plates are sandwiched. Plate
10 is formed, and the attachment plate 10 is opened to the left and right to form the tweezers body b.

加工（減少）を施した上、外形研摩加工（面取り加工、
外面部研摩等）を施す。This plate material a is made of a material such as iron, stainless steel, aluminum and titanium having a plate thickness of 3.5 to 4 mm. The plate material a is preliminarily blank-processed (roughing) into a shape close to the finished product, and the joint end is After performing plate thickness processing (reduction) on the part corresponding to 12, outline polishing processing (chamfering processing,
External surface polishing, etc.).

出来上がり製品とする。The clasped portion 11 is subjected to rough polishing, and interruption processing is performed by a wire cut, a cutting grinder or the like. (13 is an interruption groove) After that, bending is performed to open the holding plate 10 at a desired angle, and then finishing processing is performed on the inner surfaces of the holding plate 10 and the holding portion 11 to obtain a finished product.
尚、ピンセットには用途に応じて品種があるからその
形状を限定するものではない。The tweezers are not limited in shape because there are different types depending on the application.
本発明は、上述の様に構成したから次の様な特長を有
するものである。Since the present invention is configured as described above, it has the following features.
１ 板素材ａは一枚の板状のものであるから外形の形状
加工が機械加工により容易に而かも均一に行うことが出
来る。(1) Since the plate material a is a single plate, the outer shape can be easily and evenly machined by machining.
２ この板素材ａの中心に機械加工により割り込みを入
れた上、挾着板１を左右に開くだけでピンセット体ａを
作り上げることが出来るから技術的に難しい溶接や折り
曲げ加工が全くないから加工精度の高いピンセットを量
産することが出来る。2 The tweezers a can be made by simply inserting an interruption in the center of this plate material a by machining and then opening the clasping plate 1 to the left and right, so there is no technically difficult welding or bending process, so there is no processing precision. It is possible to mass-produce high-quality tweezers.
従って、機械加工により量産し、それだけ製品を安価
に提供することになる。Therefore, mass production is performed by machining, and the product can be provided at a low price.
