プを提供することを目的とする。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a method for manufacturing a ballpoint pen tip, and in particular, to a stainless steel ballpoint pen tip that does not involve paper fibers in the tip and has a good writing feel. The purpose is to provide.

In the case of stainless steel tips, the angle of caulking is an obtuse angle (66°
The sharper angle (around 40") gives better writing quality and density of handwriting.It is better in terms of the so-called smudging phenomenon where excess ink lumps stick to the paper surface when writing.
The cutting edge of the caulking part. Because of the elasticity of stainless steel, the wedge-shaped voids often entrap paper fibers when writing on poor quality paper, making writing impossible.

（実施例）
次に本発明によるボールペンチップの製造方法について
の一実施例を説明する。(Means for Solving the Problem) The present invention firstly sets the tip of the ballpoint pen tip at an inclination angle of 3.
After performing an acute crimping process of 5 degrees to 45 degrees, the tip is crimped at an obtuse angle of 60 degrees to 70 degrees, thereby reducing the above-mentioned gap and solving the problems of conventional products. I ended up doing it. (Example) Next, an example of the method for manufacturing a ballpoint pen tip according to the present invention will be described.

端カシメ部６による空隙を小さくしたものである。Reference numeral 1 designates a ballpoint pen tip, which is equipped with a ball seat part 4 having an ink guide hole 2 and an ink guide groove 3, supports a ball 5 on the ball seat part 4, and holds the ball 5 with a tip caulking part 6. In the structure that holds, the caulking roller 7
The tip 8 of the ballpoint pen tip 1 is first tilted at an angle of 3.
The tip is caulked at an angle of 5 degrees to 45 degrees (preferably 40 degrees), and then the tip of the tip 8 is crimped at an angle of 60 to 70 degrees (preferably 40 degrees).
Preferably, the gap caused by the tip crimped portion 6 is reduced by performing crimping at an angle of 66 degrees.

The figure shows the second crimping process. 1...ballpoint pen tip, 7...caulking roller 8
... Tip part (effect of the present invention) As the present invention is as described above, the ballpoint pen tip according to the present invention allows smooth writing without getting paper fibers involved even when writing on somewhat poor quality paper. It is possible to provide a ballpoint pen that can perform the following functions.
