【考案の詳細な説明】 〔産業上の利用分野〕 本考案は穴明機に関するものであり、更に詳しくは、例
えば自動車の車体を構成する金属製シート材に部品の装
着穴等を明ける目的で使用される穴明機に関するもので
ある。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hole punching machine, and more specifically, for the purpose of making holes for mounting parts in a metal sheet material constituting a vehicle body of an automobile, for example. It relates to the drilling machine used.
例えば自動車の車体を構成する金属製シート材には、部
品を取付けるための装着穴や作業穴等が多数設けられて
いる。For example, a metal sheet material that constitutes a vehicle body of an automobile is provided with a large number of mounting holes and work holes for mounting parts.
上記装着穴や作業穴の穿設は、通常ダイとパンチを用
い、前記パンチを油圧シリンダで金属製シートの上方か
ら一定圧力で降下させて、行っている。The mounting hole and the working hole are usually formed by using a die and a punch, and the punch is lowered by a hydraulic cylinder from above the metal sheet at a constant pressure.
車体を構成する金属製シート材を薄くても非常に剛性の
高い材質のものが使用されるために、パンチを動作させ
る油圧シリンダは比較的大型のものが用いられている。Since a metal sheet material forming the vehicle body is made of a material having a very high rigidity even if it is thin, a relatively large hydraulic cylinder is used for operating the punch.
一方金属製シート材には多数の装着穴が形成され、各装
着穴の間隔が広い場合は、パンチと油圧シリンダとから
なる穴明け機を複数並べて設置し、各作業穴を同時に穿
設させることができる。しかし、隣接する装着穴の間隔
が狭い場合には、穴明け機を隣接させて設置することが
できず、同時穿穴が不可能で、個々の装着穴を順番に一
個ずつ穿設しており、作業性が悪かった。On the other hand, when a large number of mounting holes are formed in the metal sheet material and the intervals between the mounting holes are wide, a plurality of punching machines consisting of punches and hydraulic cylinders should be installed side by side and each working hole should be drilled at the same time. You can However, if the space between adjacent mounting holes is narrow, it is not possible to install the drilling machines adjacent to each other, and simultaneous drilling is not possible.Each mounting hole is drilled one by one. , Workability was poor.
上記問題点を解決する手段として、パンチを併設し、両
パンチ連結して一本の油圧シリンダで動作させるように
すればよい。しかし、この手段では、同じ大きさの装着
穴を穿設する場合はよいが、大きさの異なる装着穴を形
成する場合は、各々の装着穴の穴明けに要する力が異な
るため、各パンチにバランスよく力を作用させることが
できず、同時加工ができなかった。As a means for solving the above-mentioned problems, a punch may be provided side by side, and both punches may be connected to operate with one hydraulic cylinder. However, with this means, it is good to drill mounting holes of the same size, but when forming mounting holes of different sizes, the force required to drill each mounting hole is different, so It was not possible to apply force in a balanced manner, and simultaneous processing was not possible.
この考案は、狭いところでも隣接するパンチ類と干渉す
ることなく、側方からパンチを降下させて穴明けを行え
るようにした穴明け装置を提供しようとするものであ
る。This invention intends to provide a punching device capable of punching by punching the punch downward from the side without interfering with adjacent punches even in a narrow space.

を押圧し、穴明けを行う。In the hole punching machine having the above structure, the punch pressing portion provided at the tip of the first lever is arranged above the punch arranged above the hole forming position. In this state, the fluid pressure cylinder device is expanded and contracted to push and pull the other end of the second lever,
The movement of the lever is transmitted to the first lever via the third lever, and the punch is pressed by the pressing portion provided on the first lever to punch the hole.
このようにパンチを側方から操作させるようにしたの
で、穴明け部材の上方にパンチのみを配置させるので、
穴明け部材上での占有空間を少なくできる。またパンチ
を他のパンチと近接させることができ、狭い範囲内で複
数の穴明けを同時に行える。In this way, since the punch is operated from the side, only the punch is arranged above the punching member.
The space occupied on the perforated member can be reduced. Further, the punch can be brought close to other punches, and a plurality of holes can be simultaneously drilled within a narrow range.
