本発明は、時計用板物部品のピン成形方法に関し、特に
被加工材の肉を、部分的に押し出すピン出し成形方法の
改良に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for forming pins for plate parts for watches, and in particular to an improvement in a method for forming pins in which the flesh of a workpiece is partially extruded. be.
従来のピン成形方法は、第３図に示すように、金型の構

加工材Ｃ全体をつぶし、被加工材を穴に充満させ、ピン
出しを行なっている。ａはイジェクタ−ピンである。In the conventional pin forming method, as shown in Fig. 3, the entire workpiece C is crushed using a punch d, which is a component of the mold, and a die b, which has a hole, and the hole is filled with the workpiece. , is performing pinning. a is an ejector pin.

の摩耗が多く、金型寿命が短かくなってしまう。又被加
工材全体をつぶさなくてはいけない為、非常に大きな加
工荷重が必要になるという問題点があった。However, with the above-mentioned conventional technology, the entire workpiece is crushed, causing work hardening of the workpiece, resulting in wear of the punch and die of the mold during press punching in the subsequent process. In most cases, the life of the mold will be shortened. Furthermore, since the entire workpiece must be crushed, there is a problem in that a very large processing load is required.
本発明は、この様な問題点を解決するもので、その目的
とするところは、被加工材全体に加工硬化を起こさせず
、又加工荷重も少なくてすむピン成形方法を提供すると
ころにある。The present invention is intended to solve these problems, and its purpose is to provide a pin forming method that does not cause work hardening of the entire workpiece and requires less processing load. .
本発明の時計用板物部品のピン成形方法は、パンチと、
穴を存するダイを待った金型によって、穴に被加工材の
肉を充満させることを特徴とする。The pin forming method for a plate part for a watch according to the present invention includes a punch,
It is characterized by filling the hole with the meat of the workpiece using a die that has a hole in it.
本発明の作用を述べれば、被加工材の必要部分のみをつ
ぶすだけで良い為、被加工材全体のほとんどが、加工硬
化を起こさない。To describe the effect of the present invention, since it is only necessary to crush the necessary portion of the workpiece, most of the entire workpiece does not undergo work hardening.

れて形成されるものである。Part 2 (a) is a plan view of Mandarin Duck, which is a plate part for a watch made according to the present invention, and Part 2 (b) is a side view thereof. The first part shows the pin forming method of the present invention, where C is a workpiece that is a plate part for a watch as shown in Fig. 2, d is a punch, b is a goo, and 1 is inserted into a hole on the goo side. This is the ejector pin. The workpiece is a plastically deformable metal such as steel or brass, and when the punch d protrudes from the bottom of the housing corresponding to the pin p and the die b descends from above the workpiece, it reaches the ejector pin/a of the die b. It is formed by pushing up the pin p.
パンチｄは、上昇するものでも固定されるものでもよい
。The punch d may be raised or fixed.
なお、被加工材はそのものが上下より押しつぶされるも
のではなくピンｐの部分だけにパンチ力が働くようにす
るものである。Note that the workpiece is not crushed from above and below, but the punching force is applied only to the pin p.
この場合、ピンｐの形成のためにはある程度の力で被加
工材が挟持されなければならないことは言うまでもない
。In this case, it goes without saying that the workpiece must be held with a certain degree of force in order to form the pin p.
本発明は、以上説明したように、被加工材全体をつぶす
のではなく、必要部分をつぶすことにより、加工硬化を
ほとんどなくすことができる為、後工程のプレス抜き型
の寿命を、飛躍的に延ばし、又加工荷重が少な（てすむ
為、従来２工程のプレス工程が、１工ｉで完了できる効
果がある。As explained above, the present invention can almost eliminate work hardening by crushing the necessary parts rather than crushing the entire workpiece, dramatically extending the life of the press cutting die in the subsequent process. Because it requires less stretching and processing load, the conventional two-step pressing process can be completed in one process.
