また、上記穿孔機１では、穿孔ユニット４を交換することで、穿孔刃の取付数や穿孔刃のサイズを適宜変更することができ、多様な種類の穿孔を１台の穿孔機で行うことができる。 Moreover, in the said punching machine 1, by replacing | exchanging the punching unit 4, the attachment number of a punching blade and the size of a drilling blade can be changed suitably, and various types of drilling can be performed with one punching machine. it can.

また、上記穿孔機１では、穿孔操作部３を、基台２に回動軸23,24を回動自在に配設し、回動軸23,24に操作ハンドル26を連動連結するとともに、回動軸23,24に昇降軸25を偏芯させた状態で接続し、昇降軸25に各穿孔ユニット４に対応した２個の押圧リング28を回動自在かつ左右に摺動自在に配設して構成し、また、穿孔ユニット４を、穿孔刃36,37を接続した昇降体30を台座29に付勢スプリング31,32を介して昇降可能に配設するとともに、昇降体30に穿孔操作部３の押圧リング28を滑動可能に係止するための係止溝47を形成して構成している。 In the punching machine 1, the punching operation unit 3 is provided with the pivot shafts 23 and 24 rotatably disposed on the base 2, the operation handle 26 is linked to the pivot shafts 23 and 24, and The lift shaft 25 is eccentrically connected to the moving shafts 23 and 24, and the two push rings 28 corresponding to the perforating units 4 are arranged on the lift shaft 25 so as to be rotatable and slidable to the left and right. Further, the drilling unit 4 is provided with a lifting body 30 connected to the drilling blades 36 and 37 on the base 29 so as to be lifted and lowered via the biasing springs 31 and 32, and the lifting body 30 has a punching operation unit. A locking groove 47 is formed to lock the three pressing rings 28 so as to be slidable.

そのため、上記穿孔機１では、穿孔操作部３の押圧リング28を穿孔ユニット４の昇降体30に形成した係止溝47で滑動可能に係止することができ、押圧リング28と係止溝47との係止によっても穿孔ユニット４を正規の取付状態に保持することができるので、穿孔操作部３からの力の作用で穿孔ユニット４が正規の取付状態から傾斜した状態に変位してしまうのを防止することができ、これにより、正しい位置に穿孔することができるとともに、穿孔ユニット４に無理な力が作用して穿孔ユニット４が破損してしまうのを未然に防止することができる。 Therefore, in the punching machine 1, the pressing ring 28 of the punching operation unit 3 can be slidably locked by the locking groove 47 formed in the lifting body 30 of the punching unit 4, and the pressing ring 28 and the locking groove 47 can be slid. Since the perforation unit 4 can be held in the regular mounting state even by the locking, the perforation unit 4 is displaced from the normal mounting state to the inclined state by the action of the force from the perforation operation unit 3. As a result, it is possible to prevent a perforation unit 4 from being damaged due to an excessive force acting on the perforation unit 4.

また、上記穿孔機１では、穿孔ユニット４の台座29に２個のガイド孔41,42を形成し、各ガイド孔41,42に挿通するガイドピン43,44を昇降体30に接続し、各ガイドピン43,44に穿孔刃36,37を着脱自在に配設している。 In the punching machine 1, two guide holes 41, 42 are formed in the base 29 of the punching unit 4, and guide pins 43, 44 inserted through the guide holes 41, 42 are connected to the lifting body 30. Perforating blades 36 and 37 are detachably disposed on the guide pins 43 and 44.

そのため、上記穿孔機１では、昇降体30の昇降をガイドするためのガイドピン43,44を穿孔刃36,37の取付部材として兼用することができるので、ガイドピン43,44と取付部材とを別個に設ける必要がなくなり、穿孔ユニット４を小型化・軽量化することができ、また、２個のガイドピン43,44に設けた穿孔刃36,37を着脱することで、穿孔刃36,37の取付数（１個又は２個）や穿孔刃36,37のサイズを適宜変更することができ、多様な種類の穿孔を１台の穿孔機１で行うことができる。 Therefore, in the drilling machine 1, the guide pins 43 and 44 for guiding the lifting and lowering of the lifting body 30 can be used as mounting members for the drilling blades 36 and 37. Therefore, the guide pins 43 and 44 and the mounting member are used. The drilling unit 4 can be reduced in size and weight, and the drilling blades 36 and 37 provided on the two guide pins 43 and 44 can be attached and detached to detach the drilling blades 36 and 37. The number of attachments (one or two) and the size of the drilling blades 36 and 37 can be changed as appropriate, and various types of drilling can be performed with one punching machine 1.

また、上記穿孔機１では、穿孔ユニット４の付勢スプリング31,32の中空部にストッパー51を配設している。 In the punching machine 1, the stopper 51 is disposed in the hollow portion of the urging springs 31 and 32 of the punching unit 4.

そのため、上記穿孔機１では、ストッパー51を付勢スプリング31,32の取付部材或いは位置決め部材として兼用することができるので、ストッパー51と取付部材或いは位置決め部材とを別個に設ける必要がなくなり、穿孔ユニット４を小型化・軽量化することができる。 Therefore, in the punching machine 1, since the stopper 51 can be used as an attachment member or a positioning member for the urging springs 31 and 32, it is not necessary to separately provide the stopper 51 and the attachment member or the positioning member. 4 can be reduced in size and weight.

さらに、上記穿孔機１では、台座29に昇降体30を交換可能に設けるとともに、台座29と昇降体30との間に連結具56を配設している。 Further, in the punching machine 1, the elevating body 30 is provided on the pedestal 29 so as to be replaceable, and the connection tool 56 is disposed between the pedestal 29 and the elevating body 30.

そのため、上記穿孔機１では、台座29と昇降体30とを連結具56で連結しておけば、台座29から昇降体30が離脱してしまうのを防止でき、穿孔ユニット４の取扱いが容易なものとなり、また、昇降体30の落下によって穿孔刃36,37が破損してしまうのを未然に防止することができる。 Therefore, in the punching machine 1, if the base 29 and the lifting body 30 are connected by the connecting tool 56, the lifting body 30 can be prevented from being detached from the base 29, and the handling of the punching unit 4 is easy. In addition, it is possible to prevent the drilling blades 36 and 37 from being damaged by the falling of the elevating body 30 in advance.
