本考案はポンチを構成するブロックを摺動自在に組合せ
ることで無段階にポンチの対辺距離を変えることができ
る角穴用自在ポンチに関するものである。[Detailed Description of the Invention] The present invention relates to a flexible punch for square holes in which the distance across opposite sides of the punch can be changed steplessly by slidably combining the blocks that constitute the punch.
従来、角穴用ダイスには４個の摺動可能な分割ダイスを
用いることでダイス対辺距離を無段階調節できうるもの
であるが、ポンチには前記ダイスのように目的に応じて
適宜対辺距離を変えることのできるものがなく、一般に
は、それぞれの目的に応じた各種大きさのポンチを製作
しておくかまたは断面形状を正方形や長方形に形成した
小ブロックをその都度所要数組み合わせることで目的に
応じたポンチを得るしかないのが現状である。Conventionally, dies for square holes use four slidable split dies, allowing stepless adjustment of the distance across the sides of the die, but punches, like the dies mentioned above, can adjust the distance across the sides as appropriate depending on the purpose. There is nothing that can be changed, and in general, the purpose is to manufacture punches of various sizes depending on the purpose, or to combine the required number of small blocks with square or rectangular cross-sections each time. The current situation is that we have no choice but to obtain a punch that matches the situation.
このため、所要各サイズのポンチを揃えたい場合は、ダ
イスの製作に比べてポンチの製作には多額な費用を要す
る他、上述の如き手段での組立てに多大な労力を費やし
、しかも不安定なポンチによる穴開けについての作業コ
ストの増大を招いていた。For this reason, if you want to prepare punches of each required size, manufacturing punches requires a large amount of money compared to manufacturing dies, requires a great deal of effort to assemble using the methods described above, and is unstable. This resulted in an increase in the work cost for making holes with a punch.
そこで最近特にポンチ自体の対辺距離をダイスと同様に
無段階調節できうるようなポンチが要望されているが適
当なものがないのが実状である。Therefore, there has recently been a demand for a punch that allows stepless adjustment of the distance between opposite sides of the punch itself, similar to a die, but the reality is that there is no suitable punch.
本考案は、上記要望に応えるべく考えだされたものがあ
り、４個のブロックを摺動自在に組合わせることにより
ポンチの対辺距離を無段階調節できるようにしたもので
ある。The present invention was devised in response to the above-mentioned needs, and the distance between opposite sides of the punch can be adjusted steplessly by combining four blocks in a slidable manner.
以下、その実施例を示す図面に基づき説明する。Hereinafter, an explanation will be given based on drawings showing examples thereof.

小ブロックをその都度組合わす手間もかからないため、
製作費や労力を大幅に軽減できるものである。Therefore, there is no need to manufacture a large number of punches of each required size, as in the past, and there is no need to combine small blocks of square or rectangular shapes each time.
This can significantly reduce production costs and labor.
