Abstract
A kind of bullet-shaped nib.Mainly solve existing bullet-shaped written processing technology complicated, waste material, the problem that manufacturing cost is high.It is characterized in that: processed combined by metal hollow pipe, cylinder metal rod, ball.Its advantage is that nib is combined by metal hollow pipe, cylinder metal rod, compared with the original technique directly using metal solid hopkinson bar to process, not only simplify technique, improves production efficiency; Can waste of material be reduced simultaneously, reduce production and processing cost.
Description
Technical field
The utility model relates to a kind of gel ink pen, is specifically related to a kind of bullet-shaped nib.
Background technology
Bullet-shaped nib, its traditional production method is processed to form through multiprogramming with a solid stainless steel material.Specifically, be by solid material after bottom chamfer, drill centers from it is inner, after Jing 11 road high-speed cutting boring, completes oil ink passage, and cylindrical after cutting.Forming 30 ° through front end high-speed cutting, cutting pearl bore on 30 ° of tops and bore aperture, getting through the oil ink passage of rear end, finally ball is embedded ball seat hole.
In addition, Chinese invention patent application (application publication number: CN 104097034 A, Shen Qing Publication day: 2014.10.15) also disclose a kind of method for processing pen point, by multiple working procedures such as radial cold-heading process, boring, punching presses, cylinder metal bar is processed into nib.
Above-mentioned processing technology is all that a solid cylinder metallic rod is processed into nib, and not only processing technology is complicated, inefficiency, and easily causes waste of material, and production cost is high.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of bullet-shaped nib, solves existing bullet-shaped written processing technology complicated, waste material, the problem that manufacturing cost is high.
The technical scheme that the utility model adopts: a kind of bullet-shaped nib, comprises metal hollow pipe, described metal hollow pipe top is tapered top tip part; Described top tip part center is provided with solid bar, and described solid bar top exceeds top tip part and is certain bevel angle; Described solid bar center is provided with ink hole and ball seat hole, is provided with some ink outlet troughs between described ball seat hole and ink hole; Ball is provided with in described ball seat hole.
Described top tip part is consistent with the bevel angle at solid bar top, and is 30 ° of angles.
Certain inclination angle is processed between described ball seat hole and ink hole.
Described ink outlet trough is provided with 5, and is uniformly distributed along ink hole circle week, in five-pointed star shape.
Metal hollow pipe bottom chamfer is arranged.
The material of described metal hollow pipe is stainless steel material, and the material of described solid bar is stainless steel material.
The beneficial effects of the utility model are: adopt above scheme, and nib is combined by metal hollow pipe, cylinder metal rod, relative to original directly with the processing of metal solid hopkinson bar, simplify technique, improve production efficiency; Can waste of material be reduced simultaneously, reduce production and processing cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in the figure, a kind of bullet-shaped nib, comprises metal hollow pipe 1, and described metal hollow pipe 1 top is tapered top tip part 11; Described top tip part 11 center is provided with solid bar 2, and described solid bar 2 top exceeds top tip part 11 and is certain bevel angle; Described solid bar 2 center is provided with ink hole 21 and ball seat hole 22, is provided with some ink outlet troughs 23 between described ball seat hole 22 and ink hole 21; Ball 3 is provided with in described ball seat hole 22, wherein, described top tip part 11 is consistent with the bevel angle at solid bar 2 top, and be 30 ° of angles, nib is combined by metal hollow pipe, cylinder metal rod, compared with the original technique directly using metal solid hopkinson bar to process, not only simplify technique, improve production efficiency; Can waste of material be reduced simultaneously, reduce production and processing cost.
In addition, be processed into certain inclination angle between described ball seat hole 22 and ink hole 21, therefore ball 3 is arranged on after in ball seat hole 22, and rolling effect is better.
Described ink outlet trough is provided with 5, and along the distribution of ink hole 21 even circumferential, in five-pointed star shape, can realize good effect out of ink, certainly, ink outlet trough also can be 3, and 4 are not etc.
Metal hollow pipe 1 bottom chamfer is arranged, more enough convenient installations.
The material of described metal hollow pipe 1 and described solid bar 2 is stainless steel material, and stainless steel material is more easily processed.
Embodiment should not be considered as the restriction to utility model, but any improvement done based on spirit of the present utility model, all should within protection domain of the present utility model.
