Description
【発明の詳細な説明】 ［産業上の利用分野１ 本発明はプレス部品の加工方法に関する。[Detailed description of the invention] [Industrial application field 1 The present invention relates to a method for processing press parts.
［従来の技術］
従来のプレス加工方法としては、第２図に示すように、
製品の一方を抜き加工した後製品部のみをストリッパー
で押さえて他方の抜き加工をしている。[Prior art] As shown in Fig. 2, the conventional press working method is as follows.
After punching one side of the product, only the product part is held down with a stripper and the other part is punched.
［発明が解決しようとする課題］
しかし、前述の従来技術では、ストリッパーで押さえる
製品の面積が少ないと材料の拘束力が弱くなってしまい
、製品部材料は抜き加工時にパンチに引き込まれ、他方
は逃げる状態となるため、第２図１６のように低面が平
らでなくなってしまい製品断面はきれいな長方形或いは
正方形にならない。そこで本発明は、このような問題点
を解決するちので、その目的とするところは、材料を変
形させずに打ち抜くプレス加工方法を提供するところに
ある。[Problem to be solved by the invention] However, in the above-mentioned conventional technology, if the area of the product to be pressed by the stripper is small, the binding force of the material becomes weak, and the material of the product part is drawn into the punch during punching, and the other part is Because of this, the lower surface is no longer flat as shown in FIG. 2, and the cross section of the product is not a neat rectangle or square. In order to solve these problems, the present invention aims to provide a press working method that punches out a material without deforming it.
〔課題を解決するための手段１
本発明のプレス加工方法は、第１の打抜き加工が施され
、製品となる一方の形状が形成された抜きカスを元に戻
し、前記抜きカスから前記製品の他方の形状を形成する
第２の抜き加工を有することを特徴とする。[Means for Solving the Problems 1] The press working method of the present invention involves returning the punched scraps that have been subjected to the first punching process and in which one shape of the product has been formed, and extracting the product from the punched scraps. It is characterized by having a second punching process for forming the other shape.
［作 用］
本発明の上記の方法によれば、板状の材料を打ち抜いた
部分をノックアウトにより元に押し戻してやり、目的と
する製品部と戻された部分をストリッパーで押さえ、製
品部を横方向と縦方向から拘束した状態で打ち抜くこと
ができる。[Function] According to the above method of the present invention, the part punched out of the plate-shaped material is pushed back to its original position by knockout, the target product part and the returned part are held down with a stripper, and the product part is horizontally pressed. It is possible to punch out while constraining both the direction and the length.
［実 施 例］
本発明の実施例を時計部品のバネ部加工行程の例を図面
を用いて説明をする。[Example] An example of a process for machining a spring part of a timepiece component will be explained using the drawings.

断面が変形しないで得られることから精度の高い製品が
得られる。FIGS. 1(a) to 1(d) are machining process diagrams for the spring part of the timepiece part, and 17 and 18 are the parts to be punched out. First, as shown in FIG. 1(a), a punching process is performed by sandwiching the material between the punch 11 and the knockout 14, which pushes the material upward with a spring. When the punch 11 rises, the knockout l4 pushes the punched waste 17 back to its original position, as shown in FIG. 1(b). In this state, the material sent to the next stage is removed by simultaneously sandwiching the scraps 17 and the product part 16 between the stripper 22 and the gouer 23, as shown in FIG. 1(C).
The product part 16 is restrained from the vertical and horizontal directions, and the punch 2
3, punching is performed leaving the product part l6. Furthermore, as shown in FIG. 1(d), in the next stage, the punched waste 17 is dropped, thereby minimizing the rotational force acting on the product part 6 and molding the shape of the product part. This allows the cross section of the product to be obtained without deformation, resulting in a highly accurate product.
尚、本発明の実施例を用いれば、時計部品のみならず極
細形状を有する板状プレス部品において同様の効果が得
られることは言うまでもない。It goes without saying that by using the embodiments of the present invention, similar effects can be obtained not only in timepiece parts but also in plate-shaped pressed parts having an extremely thin shape.

有する。[Effect of the invention 1 As described above, according to the present invention, the punched scraps that have been subjected to the first punching process and in which one shape of the product has been formed are returned to their original shape, and the other shape of the product is extracted from the punched scraps. Since the structure includes a second punching process to form a part, one side wall is held by the cutting scraps from the first punching process, and the upper part Since the lower surfaces are held by the mold, deformation of the cross-sectional shape that occurs during punching can be eliminated, and the product can be molded with high precision.
