Description
【発明の詳細な説明】
この発明は、頭にすりわりを有するねじ（いわゆるマイ
ナスねし）に使用するねじ回し、およびねじ回しの先端
を鍛造するための金型の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a screwdriver used for a screw having a slot in the head (a so-called slotted screw), and to improvements in a mold for forging the tip of the screwdriver.
前述のねじ回しは、ＪＩＳ−Ｂ１２Ｏ３に規格されてい
る。しかしながらねし径の犬なる程ねじ回し先端の入る
ねじ頭のすりわりの幅および長さも犬となり、このすり
わりに嵌入させるねじ回しの先端も、幅や厚みの種々の
ものを用意せねばならず、ねじ回しは犬は小を兼ねるわ
けには行かない。The above-mentioned screwdriver is standardized to JIS-B12O3. However, as the thread diameter increases, the width and length of the slot in the screw head into which the tip of the screwdriver fits also increases, and the tips of the screwdriver that fit into this slot must also be prepared in a variety of widths and thicknesses. , A dog cannot serve as a small screwdriver.
また、ねじ回しの先端をつぶして平たくするのに、鍛造
用の金型を使用するが、この金型の耐久性に問題点があ
り、この耐久性を向上させることが要望されている。Furthermore, a forging die is used to crush and flatten the tip of a screwdriver, but there is a problem with the durability of this die, and it is desired to improve this durability.
この発明においては、ねじ回しの先端を、中央部を端部
より薄くすることにより、大小のねし頭に対応しうるよ
うにし、さらにこのねじ回しの先端を鍛造する金型を、
截頭円錐形状として、前述問題点を解決することを目的
とする。In this invention, the tip of the screwdriver is made thinner at the center than at the ends so that it can accommodate large and small screw heads, and the mold for forging the tip of the screwdriver is
The purpose of the truncated conical shape is to solve the above-mentioned problems.
以下図面を参照しつつこの発明実施例を詳述する。Embodiments of this invention will be described in detail below with reference to the drawings.
第１図のねじ回しにおいて、１は本体、２は握り部であ
る。そして本体１の先端１ａは、その厚さを、中央部を
端部より薄くする。In the screwdriver shown in FIG. 1, 1 is a main body, and 2 is a grip. The thickness of the tip 1a of the main body 1 is made thinner at the center than at the ends.
このようにすることにより、大きいねし頭ｍｌ。By doing this, you can make a large ml.
のすりわりＳ、にこの先端１ａが丁度嵌入し、先端１ａ
が幅の広いすりわりＳ！の（ｌ］ｔｌ壁に当接し、ねじ
を回すのに支障ない。また小さいねし頭１−１ 。The tip 1a fits exactly into the slot S, and the tip 1a
It's a wide slit S! (l)tl It comes into contact with the wall and there is no problem in turning the screw.Also, the small screw head 1-1.
に対しても、そのせまいすりわりＳ２にも、先端１ａの
中央部の薄い個所が丁度嵌入し、ねじを回すのに支障な
い。The thin part at the center of the tip 1a just fits into the narrow slot S2, and there is no problem in turning the screw.
そしてこのような先端１ａを加工するだめの鍛造用金型
１（としては、第３図図示のような、円錐の途中を底面
と平行な平面で切・た形（この明細書において截頭円錐
形状と称する）のものとする。A forging die 1 for processing such a tip 1a (in this specification, a truncated cone shaped like the one shown in FIG. shape).
これを第３図図示のように截頭部分を対面させてこの間
にねじ回しの本体１の材ａ（、ｒＩｓ規格で表示すれば
Ｊ Ｉ ５−Ｇ３５０６硬鋼線材のｓｗＲＨ６２Ａ）を
はさんで鍛造すれば、第２図図示のような、先端１ａが
形成されるものである。This is then forged with the truncated parts facing each other as shown in Figure 3, with the material a of the main body 1 of the screwdriver (swRH62A of JI 5-G3506 hard steel wire according to the rIs standard) sandwiched between them. Then, a tip 1a as shown in FIG. 2 is formed.
そして、金型Ｉ（は回転体でもあるため、１個所が変形
すれば、金型Ｋを回転体の回転軸のまわりにそ
若干回して使用すれば、金型１（の全周を使用でき金型
Ｉ（の寿命も延びるものである。Since mold I is also a rotating body, if one part is deformed, the entire circumference of mold 1 can be used by rotating mold K slightly around the rotation axis of the rotating body. The life of the mold I is also extended.
この発明は前述のとおり、ねじ回しの先端の厚さを中央
部を端部より薄くしたから、この発明のねじ回しによる
ときは、ねじの大小、すなわちねじ頭のすりわりの寸法
の大小に対して、適応しうるものである。またこの発明
のねじ回しを鍛造する型は、截頭円錐形状としたから、
その周囲を作動面とすることができ、その耐久性を延す
ことかできる。As described above, in this invention, the thickness of the tip of the screwdriver is made thinner at the center than at the ends, so when using the screwdriver of this invention, the size of the screw, that is, the size of the slot in the screw head, can be adjusted. It is something that can be adapted. Also, since the mold for forging the screwdriver of this invention has a truncated conical shape,
The surrounding area can be used as a working surface, and its durability can be extended.
