Everyone was looking forward to watching, especially Zhang Zhuxun's eyes widened, and his shy and delicate face was full of nervousness. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

He drilled the firearms of his brothers, and his two brothers were more helpers, and the problem of misalignment of the gun pipe had been bothering him for a long time.

Yang Xianggong once said that this problem lies in the drill bit, and it is very simple to solve it, he smiled and was silent at the time, and now he finally said it.

He watched nervously, and his heart went up and down.

He watched as Yang Xianggong painted on the wooden board, slowly taking shape, and finally drew the shape of a drill bit.

This is......

Zhang Chuxun's eyes froze.

Li Tiannan's eyes widened.

He thinks that his skills in building firecrackers are also ranked first in Foshan, but the disadvantages of drilling have always troubled him.

Drill and drill often, and the whole gun will be wasted.

And he doesn't have a Suzhou steel drill bit, a fallen steel made of low-carbon steel, and the progress is slow, and he works slowly, making a bird gun a month.

Even many craftsmen are inferior to him, and the drill is drilled halfway, turned over and then drilled the other half.

I heard that there is a drill bit style that has been drilling, and I don't have to worry about drilling deviation, so I naturally look at it with my eyes wide open.

At this time, he stared at the shape of the drill drawn by Yang Xianggong and muttered, "This won't be drilled?" ”

Yang He carried a pencil and said with a smile: "Yes, with this single-sided drill bit, you can solve the problem of the deviation of the gun pipe!" ”

Seeing that Zhang Chuxun and Li Tiannan showed very excited expressions on their faces, he smiled, these two young people can be cultivated well.

After all, they are young, malleable, and their skills are also very good.

To solve the problem of the deviation of the barrel drilling, it is indeed very simple, changing the diamond structure to a single-sided drill bit structure, a simple physical principle.

Of course, no matter how simple the principle is, if this window paper is not illuminated, it may be hundreds of years or thousands of years, and no one will think of it.

In fact, at the end of the Qing Dynasty, craftsmen in many places still used diamond-shaped drill bits, and the Indians had thousands of years of history, and they had already had sculptural toys for wheels, but they couldn't think of inventing wheels for carts.

After discussing the structure of this single-sided drill bit for a long time, Yang He instructed Zhang Chuxun to first use ordinary falling steel to build a pair of such drill bits, and after the trial, if feasible, then use Suzhou steel to make them, and the drill bits will also be single-sided structures of this standard in the future.

Zhang Chuxun excitedly agreed, he couldn't wait to try it.

Zhang Zhugong watched from the sidelines, and he was just as excited, Xiang Gong taught him such top-secret skills, and he had to work hard.

Yang He decided to make six pairs of single-sided drill bits first, temporarily use one each for Zhang Chuxun and Li Tiannan, and spare and replace the remaining pairs.

Drilling is a technical job, but ordinary blacksmiths can't, but they can make pipes and other spare parts.

If the gun pipe is directly made with more refined iron, that is, within a day, Yu Blacksmith and others can also participate in the making.

It is not difficult to directly roll the barrel of wrought iron plate, the technical content is not so high, and the making of many iron tools is more difficult than the barrel, after all, the blacksmith Yu and others are old blacksmiths with decades of skills, even if they have not made the barrel, Zhang Chuxun and others will take it for a period of time, and it will be good after being familiar.

In this way, a few blacksmiths made pipes and parts according to the standard, polished copper bolts, and Zhang Chuxun and Li Tiannan drilled the bore, and it was very easy to shoot 100 new guns a month.

Yang He also designed a lathe to bring together various tools and make it more convenient to polish the drill chamber.

According to Yang He's estimate, it can basically drill a bore in half a day.

In this way, Zhang Chuxun and Li Tiannan can drill four pipes a day.

……

"What is this?"

Everyone looked at the pattern of the instrument that Yang Xianggong had drawn on another wooden board.

Looking at the instrument diagram above, it is quite similar to a bed-type structure, and then there is a bed frame, a drill bit, a moving table, a fixed groove, and a variety of accessories processing tables.

Everyone was staring at it, Zhang Chugong and Zhang Chuxun paid special attention to the drill bit above, but it was replaced with a crank handle, which was quite different from the drill bit they used in the past, and the drill bit on it seemed to be fixed.

After all, Yang He's sketching skills are still very deep, and the pattern parts are drawn very accurately, and you can see this situation at a glance.

Look at the opposite side of the drill bit, there is also a fixed groove, on which there is a pattern of a pipe-like pipe, and there is a dotted line head on the edge of the pattern, which means that when the pipe is drilled, the pipe moves to this side, not the drill bit.

This one......

Not only Zhang Zhuxun, but also Li Tiannan were shocked and pondered, and they were keenly aware of the sharpness of this drilling machine.

The special pipe is fixed and clamped, and the whole is pushed over, and the drill pipe will be unimaginably smooth.

Is......

The two young people were amazed, how did Yang Xianggong come up with it?

There are so many craftsmen in Daming, and no one thought of this.

At least Li Tiannan lives in Foshan, where it is known as the "Iron Town", where there are many craftsmen and many masters, but they are just good at craftsmanship, and they have never heard of such sharp instruments.

Look at this instrument, there are all kinds of processing and fixing tables, grinding and cutting of intermediate pipes and spare parts, etc., which can be completed on this lathe.

It's so wonderful, everyone is amazed.

Blacksmith Li looked at the pattern, and was also fascinated, for to their craftsmen, this instrument diagram was so beautiful that it was unexpectedly depicted from the hands of a Xiucai.

There was even a look of awe on his face, thinking: "Is Yang Xianggong the reincarnation of a craftsman god?" ”

He didn't understand, how did Yang Xianggong, as a scholar, know about these craftsman's things?

He has been in Pizhou City for many years, and he also knows what kind of virtue the secretaries and ambassadors of the military bureau are.

Blacksmith Yu also approached and looked carefully, and he was fascinated, and he couldn't imagine that he was old and could still see this kind of peerless weapon.

This Xin'anzhuang is really the right one.

If you stay for a long time, you will have to produce a few masters in the future.

Yang He looked at everyone's expressions and smiled slightly, this is the confluence of simple drilling machines, milling machines, boring machines, and planing machines that he created and painted in combination with this era.

The overall parts of these lathes are not complicated, and the technical content is not high, and these craftsmen can make them in front of them.

And if this simple lathe can make a few, at least Zhang Chuxun and Li Tiannan will have no problem drilling four pipes a day.

Other craftsmen can also cut and polish at the side of the lathe.

He looked at the pattern on the board, the machine was still very simple.

But while it's simple, it represents power.

The rough conversion of this power in front of him is equal to the strength of a few blacksmiths in his Xin'anzhuang district, which is more than the strength of more than a hundred blacksmiths in other big workshops.

And the products produced here will be faster and better.

It can only be imitated, not surpassed.

In fact, many revolutionary machines start out simple, but soon take on incredible energy.

……

In the making of lathes, as well as on the firecracker, there is actually a part that is indispensable, connected, fastened, and needed everywhere.

This little thing is called "standard parts" in industry, which is a very common screw bolt.

At this time, the processing of this thing is not simple, often cut out slowly, a round bar material is clamped, slowly cut off one by one, and each time the knife must be carefully cut, so as not to cut the wrong cut, and finally cut out a small bolt.

Not to mention the low processing efficiency, the manufacturing cost is also very uneconomical, the waste of materials is too large, and the requirements for workers are also high, and teachers are often needed.

So Yang He plans to use a mold-type thing to make bolts in batches, and there is also a tool for machining internal threads.

And the system of these two things is simple and simple, and difficult to say.

It's not technology, the technology of this era can't be underestimated, and many craftsmen have made handicrafts that have amazed future generations, and it is not easy to imitate.

It's the material, like the hammer spring of a flintlock pistol, which needs good steel to catch fire.

These two things have very high requirements for materials, after all, they are molds, and the use of high-carbon steel is inevitable.

Fortunately, Yanghe has 200 catties of Suzhou steel, and the material problem is basically solved.

In the midst of everyone's expectant gaze, he slowly drew the pattern of the two things on another wooden board.

With these two things, you can make standard parts such as bolts in batches.

Or the internal thread is processed. (To be continued.) )
