Description

本発明はニードル型ボールペンチップ用縮管ツールに関するものであって、より詳しくは、ボールペンチップの製造に使用されるパイプの先端部の直径を簡便に縮小させられるように構成したニードル型ボールペンチップ用縮管ツールに関するものである。   The present invention relates to a needle-type ball-point pen tip reduction tool, and more specifically, to a needle-type ball-point pen tip configured so that the diameter of the tip of a pipe used for ball-point tip production can be easily reduced. It relates to a tube contraction tool.

一般的に、ニードル型ボールペンチップは図１に示すように、インク保存管からインクが貯流して先端まで流れることができる直径の小さいパイプ形状のチップ部材２と、チップ部材２の先端部に装着されて、紙面との摩擦によって回転する際に貯流したインクがくっ付いて出ることができるようにするボール６とで構成される。   In general, as shown in FIG. 1, a needle-type ball-point pen tip is attached to a tip member 2 of a small diameter pipe-shaped tip member 2 that can store ink from an ink storage tube and flow to the tip, and a tip part of the tip member 2 And a ball 6 that allows the accumulated ink to stick out when rotating due to friction with the paper surface.

チップ部材２の先端部には、ボール６が位置するボールハウス３が形成され、ボールハウス３の裏側には安着突起４が形成される。   A ball house 3 where the ball 6 is located is formed at the tip of the chip member 2, and a seating protrusion 4 is formed on the back side of the ball house 3.

チップ部材２は、図２に示すように、従来には、比較的に内径が小さくて厚いパイプを使用しており、ボールハウス３の内径（ｄ１）は全体的に加工して安着突起４の裏側部分の内径（ｄ２）より大きく形成し、この場合、ボールハウス３の内径を全体的に切削加工することによって粗い部分（burr）が発生してインクの流れが低下し、加工量の増加によって工具の寿命が短くなるという短所があった。   As shown in FIG. 2, the tip member 2 has conventionally used a pipe having a relatively small inner diameter and a thicker pipe. The inner diameter (d1) of the ball house 3 is entirely processed to form a seating protrusion 4. In this case, when the entire inner diameter of the ball house 3 is cut, a rough portion (burr) is generated, the ink flow is reduced, and the amount of processing is increased. As a result, the tool life is shortened.

したがって、従来のチップ部材２ａは、図３に示すように、内径が大きくて薄いパイプを使用し、ボールハウス３ａに対応する部分をすぼめて、ボール６ａが位置するボールハウス３ａの内径（ｄ３）を安着突起４ａの裏側の内径（ｄ４）より小さく形成することによって、インクの流れが円滑になり、切削加工面積の減少によって粗い部分が減少し、工具の寿命も延長する効果を持つようになった。   Therefore, as shown in FIG. 3, the conventional tip member 2a uses a pipe having a large inner diameter and a thin pipe, and a portion corresponding to the ball house 3a is squeezed so that the inner diameter (d3) of the ball house 3a where the ball 6a is located. Is made smaller than the inner diameter (d4) on the back side of the seating protrusion 4a, so that the flow of ink is smooth, the rough portion is reduced by reducing the cutting area, and the tool life is extended. became.

このような従来のニードル型ボールペンチップは、製造時に、チップ部材２ａとして使用するパイプ１の先端部の直径を縮小させるために縮管装置が幅広く使用される。   In such a conventional needle-type ballpoint pen tip, a tube contraction device is widely used to reduce the diameter of the tip of the pipe 1 used as the tip member 2a at the time of manufacture.

縮管装置１０は、図４に示すように、スピンドル１１に連動構造を有して偏心状態に軸設される内側ツール１４と外側ツール１６を備え、内側ツール１４と外側ツール１６の一端部分に形成される傾斜面１５、１７の間へパイプ１の先端部を圧入させることによって縮管が行われる。   As shown in FIG. 4, the contraction device 10 includes an inner tool 14 and an outer tool 16 that have an interlocking structure with the spindle 11 and are axially arranged in an eccentric state, and at one end portion of the inner tool 14 and the outer tool 16. The tube is contracted by press-fitting the tip of the pipe 1 between the inclined surfaces 15 and 17 to be formed.

上記のように構成される従来の縮管装置は、部品数が多く、セッティング時間も長くかかるため、生産性や作業性を低下させる要因を提供する。   Since the conventional tube contraction apparatus configured as described above has a large number of parts and takes a long setting time, it provides a factor for reducing productivity and workability.

また、構造が複雑であり、精密性が要求されるため、価格が高くなってボールペンチップの生産原価を上昇させる要因となる。   In addition, since the structure is complicated and precision is required, the price is increased, which increases the production cost of the ballpoint pen tip.

本発明の目的は、このような問題点を解決するためのものであって、チップ部材製造用パイプの一端部分を成型孔に圧入させることによって簡便に縮管が行われるように構成されることにより、構造が簡単であり、作業が簡便であるため、作業性および生産性を向上させ、製品生産原価を低くすることが可能であるニードル型ボールペンチップ用縮管ツールを提供することにある。   An object of the present invention is to solve such a problem, and is configured so that a contraction can be easily performed by press-fitting one end portion of a pipe for manufacturing a chip member into a molding hole. Accordingly, an object of the present invention is to provide a needle-type ballpoint pen tip reduction tube tool that is simple in structure and simple in operation, and that can improve workability and productivity, and can reduce the product production cost.

本発明の実施形態にかかるニードル型ボールペンチップ用縮管ツールは、棒状からなる本体と、本体の一側の部分に中心軸線上に沿って形成され、一端部分にチップ部材製造用パイプの一端部分が圧入されることによって直径が縮小されるように縮管が行われる成型孔とを含んで構成される。   A needle-type ballpoint pen tip reduction tube tool according to an embodiment of the present invention includes a rod-shaped main body, a portion on one side of the main body formed along a central axis, and one end portion of a pipe for manufacturing a chip member at one end portion. And a molding hole in which the contraction is performed so that the diameter is reduced by being press-fitted.

成型孔の内径は、成型孔の一端部分から他端部分に行くほど徐々に大きくなるように形成される。   The inner diameter of the molding hole is formed so as to gradually increase from one end portion of the molding hole to the other end portion.

上記において、本体には、内径が成型孔より大きくて成型孔と連通する延長孔を中心軸線上に沿って形成し、成型孔と延長孔の間には、成型孔側から延長孔側に行くほど内径が徐々に増加する連結孔を形成することも可能である。   In the above, the main body is formed with an extension hole along the central axis that has an inner diameter larger than that of the molding hole and communicates with the molding hole, and between the molding hole and the extension hole goes from the molding hole side to the extension hole side. It is also possible to form a connecting hole whose inner diameter gradually increases.

本発明の実施形態によるニードル型ボールペンチップ用縮管ツールによれば、チップ部材製造用パイプを成型孔に圧入させることによって簡便に先端部の直径が縮小し、縮管が行われるように構成されるため、構造が簡単であり、製造作業が簡便になる。   According to the needle-type ballpoint pen tip reduction tube tool according to the embodiment of the present invention, the tip member diameter is easily reduced by press-fitting the tip member manufacturing pipe into the molding hole, and the tube reduction is performed. Therefore, the structure is simple and the manufacturing operation is simplified.

したがって、チップ部材の縮管時に作業性および生産性を向上させることが可能であり、ボールペンチップ製造時に生産原価を節減することが可能である。   Therefore, it is possible to improve workability and productivity when the tip member is contracted, and it is possible to reduce the production cost when manufacturing the ballpoint pen tip.

成型孔３０は、一端部分へチップ部材製造用パイプ１の一端部分が圧入されることによってパイプ１の縮管が行われる。   In the molding hole 30, the pipe 1 is contracted by press-fitting one end of the chip member manufacturing pipe 1 into one end.

成型孔３０の内径は、一側（図５で左側）端部から他側（図５で右側）端部へ行くほど徐々に大きくなるように形成する。   The inner diameter of the molding hole 30 is formed so as to gradually increase from one end (left side in FIG. 5) to the other end (right side in FIG. 5).
