Description
【０００１】[0001]
本考案は、パンチに関するもので、特に穿孔形状が丸以外のものに関するもの である。 The present invention relates to a punch, and more particularly to a punch having a shape other than a circle.
【０００２】[0002]
従来の抜刃は穿孔形状が丸のものであるため、その抜刃の保持については実開 平２−９７６００に見られるような方法ですることも可能であった。 しかし、抜刃の穿孔形状が長方形で、しかも薄形など、丸以外となると抜刃に 固定軸を貫通させることができず、ネジや割りピンを用いて抜刃を直接可動板に 固定していた。 Since the conventional punching blade has a round punching shape, it was also possible to hold the punching blade by the method found in Japanese Utility Model Laid-Open No. 2-97600. However, if the punching hole has a rectangular hole shape and is thin, such as a thin shape, the fixed shaft cannot penetrate through the punching blade, and the punching blade is directly fixed to the movable plate using screws or split pins. It was
【０００３】 また、抜き刃の生産方法としては、従来穿孔形状が丸以外の抜刃は材料を研磨 して作るか、あるいは鋳造によって生産されていた。Further, as a method of producing a punching blade, conventionally, a punching blade having a hole shape other than a round shape has been produced by polishing a material or by casting.
【０００４】[0004]
前者においては、ハンドルを押圧すると、それに従い作動軸が抜刃の上端を押 し、支点軸を支点として作動軸を抜刃とともに下降し、抜刃と支持穴の間のわず かな隙間でも、その隙間分だけ抜き刃が片寄りとなり、抜き刃の上部は上面板の 支持穴の前側面にあたり、下部の先端は基台の抜け穴の後ろ側板にあたり、抜穴 に挿入されないために作動不良をおこしたり、また、このような作動不良を防止 するため、抜穴を大きくすると、用紙を穿孔した際に、用紙にバリやしわが発生 した。従って抜刃を基台の抜穴に垂直に挿入するには、抜穴を固定する可動板の 寸法、および可動板の上部に架設された作動軸の位置などの寸法精度が要求され ていた。また、従来は抜刃を可動板に直接固定していたため、組みつけの手間が かかり、コスト高の原因になっていた。（図５．６．７参照） In the former case, when the handle is pressed, the operating shaft pushes the upper end of the cutting blade accordingly, and the operating shaft descends together with the cutting blade around the fulcrum shaft as a fulcrum, even if there is a slight gap between the cutting blade and the support hole. The punching blade is offset by the gap, and the top of the punching blade is the front side of the support hole of the top plate, the tip of the bottom is the back side plate of the through hole of the base, and it is not inserted into the punching hole, causing malfunction. In addition, if the punching holes were made large in order to prevent such malfunctions, burrs and wrinkles occurred on the paper when the paper was punched. Therefore, in order to insert the punching blade vertically into the punching hole of the base, dimensional accuracy such as the size of the movable plate that fixes the punching hole and the position of the operating shaft that is installed above the moving plate is required. In addition, conventionally, the extraction blade was fixed directly to the movable plate, which required assembly work, resulting in high cost. (See Figure 5.6.7)
【０００５】 また、後者の穿孔形状が丸以外の抜刃の製造に関して述べると、材料を研磨し て生産する方法においては、時間がかかって能率が悪く、量産には不向きであっ た。次に、鋳造によって生産する方法においては、正確な寸法かで作ることが困 難であるうえ、鋳造後の仕上げの際には大変な手間がかかり、これもまたコスト 高の原因となっていた。[0007] Furthermore, regarding the latter manufacturing of a punching blade having a shape other than a round shape, the method of polishing and producing a material is time-consuming and inefficient, and is not suitable for mass production. Next, in the method of producing by casting, it is difficult to make it with accurate dimensions, and it takes a lot of work at the time of finishing after casting, which also caused a high cost. .
【０００６】 本考案は以上のような問題を解決し、穿孔操作をする際、抜刃が基台の抜穴に 確実に挿入され、スムーズに作動できるようにし、かつ生産工程において抜刃に 、固定軸を容易にしかも正確に組付けることができるとともに、前記抜刃を正確 な寸法で能率よく生産することにより、安価な製品を提供しようとするものであ る。The present invention solves the above problems, and when performing a punching operation, the punching blade is securely inserted into the punching hole of the base so that it can operate smoothly, and the punching blade can be used in the production process. It is an object of the present invention to provide an inexpensive product by easily and accurately assembling the fixed shaft and by efficiently producing the punching blade with accurate dimensions.
