Description

本考案は、ドリル構造に関するものであって、特に、刃部とシャンク部が圧合され、且つ、刃部とシャンク部の間に、円錐形状頸部又は多段で形成される頸部を有する圧入式ドリル構造に関するものである。   The present invention relates to a drill structure, and in particular, press-fitting having a blade-shaped portion and a shank portion pressed together, and a conical neck portion or a multi-stage neck portion between the blade portion and the shank portion. The present invention relates to an expression drill structure.

一般に、プリント基板に使用するドリル構造は、刃部とシャンク部を含む。刃部は、プリント基板にドリル加工を実施し、刃部表面は、螺旋排列された切屑排出槽を設置し、シャンク部は、機具が固定挟持する。現在、プリント基板の高密度電子線路に対応するため、多くが、超小直径のドリルビットを使用してドリル加工を実行している。
又、作業効率を向上させるため、作業時、複数の重複したプリント基板を使用するので、ドリル加工には、長い刃部を使用しなければならない。タングステンカーバイドは、剛性と硬度がよく、マイクロ構造のドリルビットに適するので、業界では、主に、タングステンカーバイドをドリルビットの材料とし、一般には、タングステンカーバイド棒材を一体加工して、刃部とシャンク部に成型している。
ドリルビットは消耗材であり、長時間の使用において、刃部の磨損や斷裂が生じる。一般に、刃部の磨損後、ドリルビット全部が廃品となる。タングステンカーバイドの材料コストは非常に高く、ドリルビットの再利用ができなければ、材料コストが高くなり、経済的でない。 Generally, the drill structure used for a printed circuit board includes a blade portion and a shank portion. The blade part drills the printed circuit board, the blade part surface has a spirally arranged chip discharge tank, and the shank part is fixedly held by the tool. Currently, many drills are performed using ultra-small diameter drill bits to accommodate high-density electronic lines on printed circuit boards.
Also, in order to improve the work efficiency, a plurality of overlapping printed boards are used at the time of work, so a long blade must be used for drilling. Tungsten carbide has good rigidity and hardness and is suitable for micro drill bits. In the industry, tungsten carbide is mainly used as a drill bit material. Molded on the shank.
The drill bit is a consumable material, and the blade portion is worn or cracked when used for a long time. Generally, after the blade portion has been worn away, the entire drill bit is discarded. The material cost of tungsten carbide is very high, and if the drill bit cannot be reused, the material cost becomes high and it is not economical.

上述の問題を解決するため、本考案は、圧入式ドリル構造を提供し、その刃部とステンレス製のシャンク部は、圧合で結合し、且つ、刃部とシャンク部の間は、円錐形状頸部又は多段で形成される頸部を有する接続構造であって、材料コストを節約し、ドリル品質を良くすることを目的とする。 In order to solve the above-described problems, the present invention provides a press-fitting drill structure, the blade portion and the stainless steel shank portion are joined by press fitting, and the conical shape is formed between the blade portion and the shank portion. It is a connection structure having a neck or a neck formed in multiple stages, and aims to save material costs and improve drill quality.

上述の目的を達成するため、本考案の好ましい態様による圧入式ドリル構造は、第一棒体と第二棒体を含む。第一棒体の前端はシャンク穴を設置し、且つ、第一棒体は、第一接続部分とシャンク部分を形成する。第二棒体は、順に、切刃部分、第二接続部分および挿入部分を形成し、挿入部分の末端は面取り構造を形成し、挿入部分はシャンク穴内に挿入され、且つ、第一接続部分と第二接続部分は連接して、接続構造を形成する。 To achieve the above object, a press-fitting drill structure according to a preferred embodiment of the present invention includes a first rod body and a second rod body. The front end of the first rod body is provided with a shank hole, and the first rod body forms a first connection portion and a shank portion. The second rod body in turn forms a cutting edge portion, a second connection portion and an insertion portion, the distal end of the insertion portion forms a chamfered structure, the insertion portion is inserted into the shank hole, and the first connection portion and The second connection portions are connected to form a connection structure.

本考案は、価格が高いタングステンカーバイドに代わって、安価なステンレス材料をシャンク部とし、コストを節約することができる。また、面取り構造の設計により、第一棒体と第二棒体の結合が確実に、且つ、同芯度が高くなり、ドリルパフォーマンスが向上する。   In the present invention, instead of the expensive tungsten carbide, an inexpensive stainless steel material can be used as the shank portion to save the cost. In addition, the design of the chamfered structure ensures the connection between the first rod and the second rod, increases the concentricity, and improves the drill performance.
