Description

この発明はパンチ刃に関し、特に、例えば紙などのシート状物に穿孔用刃に対応する複数の孔を一度にあけることができる手動型穿孔装置に用いられるパンチ刃に関する。   The present invention relates to a punch blade, and more particularly to a punch blade used in a manual punching device that can make a plurality of holes corresponding to the punching blade at a time on a sheet-like material such as paper.

この発明の背景となる従来の穴あけ装置の一例が、例えば特表平８−５０１０２５号公報（特許文献１参照）に開示されている。特許文献１に開示されている穴あけ装置は、複数のパンチ部材を有するものであって、複数のパンチ部材に対応する複数の孔をシート状物にあけようとするものである。   An example of a conventional drilling device that is the background of the present invention is disclosed in, for example, Japanese Patent Publication No. 8-501025 (see Patent Document 1). The punching device disclosed in Patent Document 1 has a plurality of punch members, and attempts to open a plurality of holes corresponding to the plurality of punch members in a sheet-like object.

ところが、特許文献１に開示されている穴あけ装置では、パンチ部材が穴抜きされる穴の厚さに相当する厚さを有する材料で形成されているので、パンチ部材をプレス加工により製作するときに刃先にだれを生じ易く、先鋭な刃先を製作しにくい。それゆえに、該パンチ部材によって穿孔された穴はきれいな形状にならない。しかもパンチ部材の加工に手間や時間がかかってしまい、製造コストを上げる。   However, in the punching device disclosed in Patent Document 1, since the punch member is formed of a material having a thickness corresponding to the thickness of the hole to be punched, when the punch member is manufactured by press working It is difficult to produce a sharp edge on the blade edge. Therefore, the hole drilled by the punch member does not have a clean shape. In addition, it takes time and effort to process the punch member, which increases the manufacturing cost.

それゆえに、この発明の主たる目的は、先鋭な刃先を手間をかけることなく製造することができるパンチ刃を提供することである。   Therefore, a main object of the present invention is to provide a punch blade capable of manufacturing a sharp blade edge without taking time and effort.
