Abstract

<P>PROBLEM TO BE SOLVED: To keep and elongate the cutting-off ability of a punching blade for cutting off a product from a sheet having a solid portion formed by hot working. <P>SOLUTION: A punching blade 1 is manufactured according to the shape of an object to be cut off, and is arranged on a holding stand 2 for holding the punching blade. A protective wall 3 is provided around the punching blade. The gap between the protective wall and the punching blade depends upon the object to be cut off, but usually is within the range from 2 to 5 mm. By this protective wall, the pressure at the contacting portion of the punching blade and the object to be cut off is dispersed, and the load to the punching blade is reduced, and the service life of the punching blade can be elongated. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、熱成形された立体部分を有するシートから製品を打ち抜く抜刃の切断能力を保持、延長する為の機構である。  The present invention is a mechanism for maintaining and extending the cutting ability of a punching blade for punching a product from a sheet having a thermoformed three-dimensional portion.

合成樹脂板、フィルムなどの熱成形された成形品は、プレスなどで打ち抜きされることが多いが、その際に使用される打ち抜き刃の損耗は少なくない。。  Thermoformed molded products such as synthetic resin plates and films are often punched with a press or the like, but the wear of the punching blade used at that time is not small. .

そのために打ち抜き刃の交換、作業の停止などの無駄も多く、当然必要経費も高騰する。  For this reason, there is a lot of waste such as exchanging the punching blades and stopping the work, and the necessary cost is naturally increased.

合成樹脂の熱成形品は、それぞれ形状が異なり、当然使用する打ち抜き様の抜刃の形状も、その熱成形品に応じて作成するが、本発明はその抜刃が作動する外側に防護壁を作成するものである。  Thermoplastic products of synthetic resin are different in shape, and naturally the shape of the punching blade used is made according to the thermoformed product, but in the present invention, a protective wall is provided outside the punching blade. To create.

この防護壁により、抜刃と打ち抜かれる合成樹脂熱成形品との接触する部分の圧力が分散され、抜刃の負荷が軽減され、抜刃の耐用期間を延長させることが出来る。  This protective wall disperses the pressure at the contact portion between the punching blade and the synthetic resin thermoformed product to be punched, reduces the load on the punching blade, and extends the useful life of the punching blade.

以下、本発明の実施の形態について述べる。
抜刃（１）を打ち抜く対象物の形状に従い作成し、その抜刃（１）を保持する保持台（２）に設置し、その周辺に防護壁（３）を設ける。この防護壁（３）と抜刃（２）との間隔は、打ち抜く対象物により変動するが、通常２ｍｍ乃至５ｍｍ程度で良い。Hereinafter, embodiments of the present invention will be described.
The punching blade (1) is prepared according to the shape of the object to be punched out, placed on a holding stand (2) that holds the punching blade (1), and a protective wall (3) is provided around it. The distance between the protective wall (3) and the extraction blade (2) varies depending on the object to be punched, but is usually about 2 mm to 5 mm.
