How difficult is it to manufacture ballpoint nibs Ren Zhifang

The nib and ink are the key to the ballpoint pen, where the nib is divided into a ball on the nib and a ball body. At present, tungsten carbide balls are the most widely used at home and abroad, and China has a good foundation, which can not only meet the needs of domestic production, but also supply a large number of exports. But the production of spheroids, both equipment and raw materials, has long been in the hands of Switzerland, Japan and other countries.

It takes more than 20 processes to produce a small ballpoint nib, and the traditional process needs to be processed separately. In order to meet the demand for exports, domestic pen manufacturers began to adopt a large number of integrated production equipment of Swiss Mikron Company to improve quality and production efficiency.

Foreign production equipment has relatively higher requirements for raw materials, and domestic stainless steel wire rod cannot be applied, so it must rely on free-cutting stainless steel wire rod imported from Japan. At the same time, the matching ink also has to be imported from Germany, Japan and other countries. As a result, China's current ballpoint pen production is the first, but the core materials and equipment rely on a large number of imports of "embarrassing" situation.

Moreover, compared to the steel industry, pen making is a small industry. The output of a steel mill in one day may be enough for the pen industry to digest for a year. For steel mills, this profit is insignificant, it has no incentive to engage in R&D and production, and pen companies do not have enough strength, so they rely on imports.

The state supports and encourages scientific and technological innovation, and patent examiners, on the contrary, find out how to set up obstacles to affect patent approval.

Numerous Examiners Fabricate Facts: Comparative Document 1 (US 2018 0199243

a1) the unachievable outer diameter of the spring is equal to the specific embodiment.

Why do the examiners always go against scientific common sense, insist on erroneous rejections, and do not change their motives so far?

Patent application No. 2016103139119 After five years of substantive examination, reexamination, and litigation, the examiner deliberately fabricated the so-called specific embodiments that did not exist in comparison document 1 out of nothing. Because, assuming that the outer diameter of the densely wound spring 23 is equal to 0 25mm, and the inner diameter of the densely wound spring wound by the top filament diameter of 0 1mm is only 0 05mm, it is obvious that the fine hole of the densely wound spring that is smaller than the diameter of the hair cannot ensure that the neutral ink with higher thixotropic viscosity flows smoothly in the densely wound spring hole, and the ink flow rate of this special large-diameter ballball pen tip that is larger than becomes less, and the stitch becomes faint and broken when the pen nib is written, and the opposite teaching that the invention cannot be realized is directly given.

Comparison file 1 adopts a jackscrew structure with a reserved length greater than the radius of the ball seat. The technical scheme of the extremely shortened (ultra-short) jacking wire stable anti-polarization structure (i.e., the length of the jacking wire of the present application is less than the radius of the ball seat) is not disclosed; Comparison document 1 can not solve the same technical problem as the needle tube spring nib of the present application, "to prevent the tip end of the top wire from squeezing between the ball and the gap between the ball and the ball seat"; Comparison document 1 cannot achieve the same technical effect as the present application: "simple structure, reliable performance, convenient for pen nib matching and assembly, short and accurate positioning of the top wire in the tube hole, smooth ball rotation and ink circulation".

The elastic full needle tube ballpoint pen nib is based on the urgent needs of the key core technology of the international leading and independent innovation scientific and technological research in the field. Chenguang Stationery's invention patent CN102848793B background technology describes: "Since the needle tube type nib is so popular, why has the needle tube spring pen nib not been invented after the advent of the ordinary spring pen nib".

Because the present invention technology is mature, practical and reliable, many ballpoint pen manufacturers hope to adopt the product upgrade by leaps and bounds after the confirmation of rights, and improve the scientific and technological level of China's ballpoint pen manufacturing country to become a creative power.

How difficult is it to make a ballpoint pen tip? There are very few countries in the world that can afford to make it!

China can make ballpoint pen with a small ballball. In the ballpoint pen nib, there are also five grooves to guide the ink and the processing accuracy reaches the order of 1 mm, so it is difficult to develop.

China can now manufacture ballpoint pens, but the quality needs to be improved, the process used in ballpoint pens is relatively fine, so this technology is more difficult to master, so many people now use ballpoint pens are the technology of other countries.

Yes, because the ballpoint pen is small in size and requires extremely high operating skills, it is more difficult, and the surface of the ballpoint pen is smooth and difficult to polish.

The ballpoint pen is not only a tool for students to learn, but also has long become a necessity in people's daily life, precisely because the ballpoint pen has become a daily necessities that we are accustomed to in life, and everyone ignores itTo produce a ballpoint pen, you need to go through layers of processes. It can be said that it is from the outside to the inside, fine to the tip of the nose, in order to form a smooth and easy-to-write ballpoint pen.

In the process of making a ballpoint pen, the tip of the ballpoint pen is the most important part. First of all, the beads of the ballpoint pen nib must be very wear-resistant, so to use tungsten carbide, which is second only to diamond, as the material, tungsten carbide needs to be made into small particles with a slightly larger standard size. They are then spread out on a grooved plate and these small particles are routed into a circular groove, exposing only the top of it.

Secondly, a heavy, flat top plate is placed on top of these small particles, and grinding oil is injected between the two discs so that these small particles are soaked in a slippery mixture containing powdered diamonds. Then rotate the lower plate, so that these small tungsten carbide particles in the circular groove continue to churn and roll, with the groove wall, top plate and each other continuous contact, diamond powder constantly grind off the corners of these small particles, so that they gradually become round and bright.

Finally, the ball is put to the last test, because it is too smooth to stick to the ink and cannot write. So,During the grinding process, these small balls are taken out and tested several times a day until they are produced with a moderate smoothness that meets the standardsIn this way, it takes about dozens of hours of intermittent grinding to produce a small ballpoint pen bead of tungsten carbide. You can see how fine the ballpoint pen is.

How is the ballpoint nib made? After reading it, I realized why China has not been able to manufacture it for many years.

That's right, it's really precise, at present, only one company in Japan makes a ballpoint pen nib is the best, which has a high technical content, there are a lot of high-tech in this world that you haven't seen, it looks simple, in fact, it's all technology.

The production of ballpoint pen nibs is a high-precision technology, and only three countries in the world can make it.

This is very precise, and only one Japanese company does it best.

In fact, it is normal for science and technology to be able to do such a pen now, and aircraft cannons can be made, isn't this kind of thing very simple?

With such a powerful science and technology, making a ballpoint pen is a very simple thing, don't be surprised, don't say unimaginable, if you say this to others, others will laugh at you, you know?

The society of love has been studied to the age of the garden, is there anything smaller than an atom? A ballpoint pen nib is just a few millimeters, atoms, it's a few microns and microns, you have to think about how many nanometers.

Why don't you ask how the computer and mobile phone are done, there are so many things you don't know, not only you, I don't know why you don't ask how the computer and mobile phone are done, there are so many things you don't know, not only you, I don't know.

Although the tip of a ballpoint pen looks very simple, with only a small metal bead, it is not so simple to make the bead rotate smoothly and let the ink flow out during useThe manufacturing process is very delicate and requires a high level of skill and skill, just like carving a pattern on the hair, and the production process is very difficult.

In addition, it is necessary to choose the right material and weight of the metal, so that it can be polished and used as a metal bead in the ballpoint pen, to ensure that the volume of the bead is not too large or too small, so as to ensure that the water can be smoothly produced when writing, and will not overflow the ink, which is convenient for everyone to write.

In fact, although such a technology sounds very sophisticated and complex, it is naturally not a problem for some countries to learn if they really want to learn, why are only 3 countries in the world doing it? This is because the profit margin of the ballpoint pen itself is very small, and the process of making it is particularly troublesome, so,Most countries in the world are very disgusted with this cumbersome and unprofitable process, so they often prefer to import ballpoint pens from other countries rather than choose to make them themselves.

Even the world's famous Switzerland, which pays attention to fine craftsmanship, has not mastered how to make a ballpoint pen nib, which shows how difficult this humble ballpoint pen nib is, so some people say that "the production tool of a ballpoint pen nib is more complicated than building an aircraft carrier". This is an exaggeration, but it is not unreasonableChina is one of the three countries in the world that has mastered this technology, which is enough to show that our people are careful and have a high level of mastery of fine craftsmanship, which is really very proud.

Because the nib is relatively small, it requires a very delicate process to manufacture, a technique that few countries can achieve.

Because ballpoint pen nibs are high-precision products, they are very difficult to produce, and other countries have not yet mastered this technology.

Because the ballpoint pen nib is small, it is a delicate job that requires a high level of craftsmanship, which is not available in other countries.

Because one country cannot be completely manufactured, it needs parts from other countries.

Recently, "China can't make a small ballpoint pen bead" has become a hot topic among netizens. With an annual output of more than 40 billion ballpoint pens, China is already a well-deserved pen-making country, but a large number of ballpoint pen nibs need to be imported. The production of the nib ball body, both equipment and raw materials, has long been in the hands of Switzerland, Japan and other countries.

Relevant experts said that every small deviation will affect the fluency and service life of the pen nib, the opening thickness of the nib is less than millimeters, but also take into account the writing angle and pressure, the ball and the nib, the ink groove must be matched "seamlessly", and the processing error can not exceed the millimeter. <>

A ballpoint pen, or ballpoint pen, is a writing instrument that uses dry-thick ink and is brought out and transcribed onto paper by means of a freely rotating steel ball on the tip of the pen. Ballpoint pens have the advantages of simple structure, easy to carry, smooth writing, and suitable for copying, so people from all walks of life from school students to office building clerical staff are happy to use it.

A ballpoint pen is a pen that uses tiny, rotating balls made of brass, steel, or tungsten carbide to release ink onto the paper as you write. The ballpoint pen is very different from its predecessors – reed pens, quill pens, metal nib pens and fountain pens.

The writing principle of the ballpoint pen is mainly to use the ball ball to produce friction in direct contact with the paper surface when writing, so that the ball rolls in the ball seat and brings out the ink or ink in the refill, so as to achieve the purpose of writing.

A ballpoint pen is a pen that uses ink and different pigments to write. The tip of the pen is a small steel ball, which is embedded in a small cylindrical copper bowl, and then connected to a plastic tube filled with ink, and the ink flows down from all sides with the rotation of the steel ball.

The pigment of ballpoint pen ink is a dye. There are three main ink colors: blue, red and black, among which blue ink is the most used. In the past, the pigment components in blue ink were salt-based blue and salt-based blue lotus, and the solvents were oxidized castor oil and ricinoleic acid.

Because salt-based dyes are not lightfast (lightfastness is only grade 1-2), heat-resistant, acid-alkali resistant, so the durability is poor, and it has been eliminated. The "424" blue ballpoint pen and the "322" black ballpoint pen sold on the market have good durability in handwriting.

It is not uncommon to report that scented ballpoint pens are toxic, and the volatile organic compounds contained in inferior scented stationery are toxic and have certain damage to the human body; However, there have been no incidents of poisoning due to the normal use of oil-based ballpoint pens that are not adulterated with volatile organic compounds. <>

In the past, it was all imported. It seems that you can do it yourself now. However, the quality is still not good.

Nonsense, laughing at me. 30 years ago, small rural factories in Yiwu could make ballpoint pen nibs.

I hope that we can make a very good ballpoint pen in China, I don't know what the current situation is. It's still a big problem to build it but it doesn't work very well.

I didn't bother to make these things in Yiwu, and I made a line, and then this line was stopped a year earlier.
