"Hey, I said, it's still Western, it's golden...... If I were a great monk, I would tell you that you are in the southern sea, belonging to the water, and drown you bastard. It seems that this may really be a high-ranking monk, and ordinary cultivation will definitely not be able to endure it. What should I do now, Wang Anshi is also blind, why did he choose you? ”

Humbled! Hong Tao felt that no words were enough to describe Zhu Bajin's overall style. He's not stupid, he's not bad, he's not grumpy, he's muddy.

There is no cure for this problem, you can hide if you can, and you can only endure it if you can't hide it. He couldn't change it if he killed him, because he didn't realize that he was different from others, and he thought it was normal.

A muddy man is gone, the front heel and the back foot are kung fu, and a strange man is here again.

At that time, Hong Tao was pouting his ass and squatting in the Jinhuo workshop with Wang Datou and other craftsmen to teach new technologies, and he didn't notice that anyone was standing quietly outside the window, seeing and hearing every word and deed and every move in the house.

It stands to reason that Weiqiao Town has only one official road and two waterways connecting to the outside, and they have all been blocked by the Water Tiger Wing Forbidden Army, and they can't enter without the Arabic numeric identity card of Wujin Xing. Even with an identity tag, each process is led by a technician, and new faces need to be checked for identity, which is difficult to blend in.

The path is even more impossible, Hong Tao came here, the construction site has not started, so the craftsmen and the forbidden army cut down all the nearby woods, all the grass burned, and dug a two-meter-deep, two-meter-wide canal along the scope of Huangzhuang, which is introduced from Bashui and released by the Wei River, which is not only a moat, but also the source of domestic sewage inside the base.

There is a 15-meter-high watchtower every 300 meters on the inside of the canal, on which the soldiers of the Forbidden Army look out day and night, and it is not absolutely impossible to cross the ditch, climb over the wooden fence, avoid the lookout post, and evade the patrol with the hounds to infiltrate the base, but it is also even more difficult.

If you can get in, you have to be able to get out, the entry and exit system of Weiqiao Town is as strict, and what comes in does not mean that you can go out. Why did you come in with so much effort and at the risk of being shot?

But there is a situation that can come in, and Hong Tao will not be notified in time, that is, the imperial court sent someone to come, and the person who came is still an acquaintance, at least the forbidden army of Shui Huyi knows it, or Gao Cuifeng, who is in charge of the actual management of the base.

This person came in this way, and immediately took over the control of the Water Tiger Wing with the holy decree, and no one was allowed to notify the horse, and then took Miao Kui and Gao Cuifeng around the base for a while, and finally came to the golden fire where the horse was, just in time for the horse to pout inside and fill the expert.

What is the flood blowing? It's really not a boast, he pushed the metal processing technology of the Song Dynasty forward for at least six or seven hundred years.

At this time, he was holding a small iron ring and a string of round and shiny steel balls in his hand, and then ordered the king to use a wooden hammer to chisel an iron ring with a smaller diameter directly into the middle of the big iron ring and a circle of steel balls.

"Well, yes, this set of flower shelves is good, and the beads are neatly polished. See, this is called a ball bearing, put it on the car, the car is inserted in the middle, and you don't need to pull it on the track at all, you can run far with a kick. Now don't wonder how to make our ore cart run faster, hurry up and figure out how to slow down, otherwise it can take a string of ore carts directly into the Wei River! ”

There were a few things that looked similar to each other, and it seemed that this was not the first time that this experiment had been done, and none of them would satisfy the colt.

Bearing? Can you make bearings in ancient times? Why didn't you say it, if steel could be smelted in ancient times, you could make a simple hydraulic or animal power stamping machine, or a punch.

With punches, modern high-speed ball bearings can't be made, but cast iron ball bearings that are much lighter than wood biting wood are really not too difficult.

The shape is easy to make, can it really be used? Hong Tao can be responsible to say that with his own two-knife metal heat treatment college student, he must be able to use it, and it is very easy to use.

This thing is an important practical experiment in the third year, and the college students who are trained by Shougang are slightly different from ordinary college students in terms of curriculum, and pay more attention to practical hands-on ability, but not too much in theory.

If Hong Tao had taken sick leave if he had nothing to do, he would have spent less than half of his time in different factories in four years, from coking to metal processing, and every process would have to be seen and touched.

To put it bluntly, the company does not plan to make a group of nerds, and immediately after graduation, they have to go to work, while working as an intern technician, while continuing to learn technology with the master.

As for the things in the books, they have to throw away all the things that should be thrown away, and 80% of them are not used. Only when you climb to the level of assistant engineer will you find that the books you read when you go to school are so important, and if you want to continue to climb up, you can't get a job title without theoretical knowledge!

The words are far away, the ball bearings made by Hong Tao in the fifties and sixties will be done in many small factories, at that time the production capacity of large factories can not keep up, and the masses have to produce and live, and they can't even have a bearing.

So the big factory sent technicians to the following to guide the production of small factories, and in some places there was not even an earthen blast furnace, so it was cast with scrap molten iron, and then bought ready-made round steel to make steel balls by hand.

What? Lathe, my God, if there can be a lathe in remote villages, why do people bother with this effort. There is no electricity in the local area, and having a flashlight is considered high-tech.

This kind of cast iron steel ball bearing was forced out by relying on the wisdom of the vast number of working people in the general environment where there were conditions to do it and no conditions to create conditions.

Its inner and outer rings are cast with white iron, steel molds and sand molds, and the same as the casting pig iron furnace, the details are even simpler, no need to find any old craftsmen, Zhu Bajin's apprentices will get it.

The steel ball must not be cast, it has to be put on the hand-cranked cutting machine with a steel bar of appropriate thickness to cut into a small steel block one by one, and then put it into the tempering furnace for tempering to reduce the hardness and increase the machining performance. To put it bluntly, it is to make the small steel blocks of this section soften, otherwise the next step will not be easy to form.

Find a steel ingot and use a harder steel chisel to make a semi-circular depression on it, and then find a smaller steel ingot to make such a depression as well. The small pieces of steel ingots are loaded onto the hydraulic forging hammer and aligned up and down through the rail, which must be very accurate.

At this time, take out the small steel block that has been tempered, put it in the groove of the large steel ingot, and drop the hammer...... Bang Dang...... A semi-finished spherical ball came out, clamped it away with iron tongs, and put another ...... Bang Dang...... Another semi-finished product came out.

If you want to speed up your production, don't take up a lot of hammers, it's too wasteful. It is only necessary to make a few more semicircular grooves on the large ingot, and then fix a few more small ingots with the same grooves on the forging hammer. Every time it clicks, N semi-finished steel balls will be rushed out.

Remember, it's a half-finished product, and it's not too round and has burrs. The next step is to grind the stone, but replace the upper part of the grinding disc with wood, then paste the cowhide, put the semi-finished ball and the sand of the same thickness together, and press the weight to start grinding.

When to grind the punch marks and burrs on the ball, it is not enough to finish the work, anyway, the waterwheel is not tired, and it turns 24 hours a day, and it is idle to be idle.

In fact, it really doesn't take that long, sometimes it looks very hard, but it can't resist the relatively soft friction, the key is the number of times.

Is this rounded? No, it has to be replaced with a smaller grinder, finer sand, and a lighter heavy object to rotate, similar to a ball mill.

This time it's a finished product, right? No, no, no, it's still far away, and you have to use a wood grinding disc to paste the cowhide polishing, and the shining tile shines out of the figure, and it's embarrassing to call it a ball!

The polishing step is also over, and it should be considered a finished product. Wait, it's not enough, because these balls are not necessarily the same size, almost not at all, just like that.

Now it's a small plank with the same drill bit to drill out a large pile of dense holes, and then smooth the burrs around the holes by hand. It's the standard for the size of the balls, and any ball that can pass through these small holes is considered qualified.
