Chen Zijian: "This matter is handed over to you and your brother-in-law, I can lend you 50,000 silver in the early stage, how to start it, I will give you a charter, whether you can make money in the future depends on your ability." ”

The teahouse was opened, Chen Zijian put the teahouse in the ranks of private enterprises, and anyone could open it if the restrictions were relaxed, Li Jiajun was just a pioneer, like this kind of private enterprise, so that private enterprises are more flexible than state-owned enterprises, if the teahouse is placed in a state-owned enterprise, there are some small materials that are used, Chen Zijian really has no effort to take care of it.

It is more reasonable for a private enterprise like this to be handed over to private management, and the experience of later generations of Huaxia has proved that there is no need for Chen Zijian to test it again.

Li Jiajun left with excitement, attracted by the scene described by Chen Zijian, and this was something that Chen Zijian personally explained, and the 10,000 taels of silver he gave as an upfront expense, it was difficult for the business of the teahouse to be poor.

Leaving the Dongfang Community, followed by six guards, as the head of the Volunteer Army, isn't it normal to have a few guards. Someone below reacted to the situation before, and no one in Zhangjia Village could solve this situation, and then it was handed over to Chen Zijian to deal with, there are quite a lot of things, and there are a few things to be dealt with first.

First, the transportation capacity of the transport team has reached a bottleneck, and the use of a wheelbarrow is easier than carrying it on both shoulders, but now the transportation task of the volunteers is getting heavier and heavier, and it is difficult to improve the transportation capacity without increasing the number of manpower, why not increase the manpower, now the number of the transport team has been very bloated, and then the management of manpower is more cumbersome, Chen Zijian wants to solve the problem of improving the transportation capacity of a single person, from the original weight of 100 catties per transport to 150 to 200 catties.

As for the use of ox carts or horse-drawn carts, this is not easy to solve for the time being, there are a lot of cattle and horses in the territory of the volunteers, at present, the volunteers control a total of about 5,000 cattle and horses, and other places also need to use animal-powered carts, it is impossible to use all of them for the transport team, such as the volunteer army to go out to clean up the operation, it is necessary to use fast horses to transmit information, if there is no fast horse, with two legs to transmit information, the consequences are unpredictable.

Improving transportation capacity has become a problem that Chen Zijian wants to solve, to solve this matter, Chen Zijian thought of rolling bearings, before Chen Zijian asked the carpenter to make a trolley with a diameter of three centimeters as the support of the wheel, the weight of transporting one hundred to one hundred and fifty catties is OK, after increasing to two hundred catties, it will be very difficult for individuals to use the trolley, if you add a plurality of rolling bearings in the iron rod, so that even if the weight of three hundred catties is transported, it can be easily transported, which is the benefit of bearings.

There is also Zhangsha railway is being built, after a period of time can be completed, the railway transport vehicle has not yet been built, a vehicle after transporting goods may weigh more than a few tons, if there is no bearing to reduce friction, then with horsepower can pull the vehicle is a big problem, bearing problem is urgent.

Riding a horse to the industrial zone, the steel plant is built here, ten miles away from Zhangjia Village, to avoid the steel plant polluting Zhangjia Village, this is a small-scale steel plant do not need to worry, and so on in the future expansion of the steel plant, it must be far away from the residential area. Small-scale steel mills are unwarranted. If it is a personal blacksmith shop, it will be fine directly in Zhangjia Village, and the pollution depends on the scale.

As the best leader of Zhangjia Village, if you want to do half of the things easily, after coming to the high-speed rail factory, let the steward find a blacksmith with good skills, and then sit there drinking tea and waiting.

Steward Zhang quickly called the blacksmith who met the chief's requirements, and he didn't need to know why the chief was looking for someone.

Chen Zijian looked at the blacksmiths and said leisurely: "What I want to make is called a bearing!" I'm going to make eight balls out of fine steel, and I'm going to polish and round them. Then two steel rings will be cast, one large and one small, and the steel rings will leave a track of two steel balls, one inside and one outside. The eight steel balls are then allowed to rotate on the orbit of the steel ring. Finally, make two iron cages and fix these steel balls inside the steel rings so that they do not collide head-to-head. ”

Hearing Chen Zijian's words, the ten blacksmiths were a little confused. They have never seen rolling bearings, and they don't know what Li Zhi is talking about when they listen to Li Zhi's words, there is a feeling of talking about chickens and ducks, there is no real thing, just Chen Zijian said an object, the blacksmith has no concept in his mind, this situation Chen Zijian already knew, and picked up a bearing from the side. This is, of course, purchased by the space-time trading center.

Let Chen Zijian solve the tens of thousands of bearings of the transport vehicle, or more than 100,000 bearings, Chen Zijian will not be such a loser if he has gold, if he buys a few as samples, then there will be no problem, buy a sample and let the blacksmith copycat, the bearing performance of the cottage is not to be purchased by the space-time trading center, but it is used to deal with Chen Zijian's requirement of 300 catties of transportation weight easily.

There is no physical blacksmith confused, after seeing the bearing that the chief said, Boss Zhou took it and turned the steel ring in the middle according to the chief's requirements, and then the steel ring turned fast, as if he couldn't stop, and waited for more than ten breaths, the bearing stopped rotating, and the blacksmiths around him looked curious.

Don't look at them for half their lives, they don't understand what this thing is used for.

"Ahem!"

Attracting the blacksmith over, Chen Zijian said, "This is used for vehicle transportation, and the original iron rod is modified with this bearing." ”

After listening to Chen Zijian's explanation, thinking about the way the steel ring had just turned, everyone suddenly realized.

Next, the bearing production is divided into five processes. The first process is to make two steel rings, one large and one small. The second process is to cut the steel rods in small sections as raw materials for making balls. The third step is to heat the ball raw material, and then beat a small section of steel rod into a ball by placing the high-temperature and soft ball raw material on a steel mold. The fourth step is to polish the balls with a good porcelain clay grinding wheel and a stainless steel grinding disc to eliminate burrs and polish the steel balls. The last process is to make two cages out of iron sheets, clamp the balls on both sides, and fix the steel balls to the predetermined position of the track.

Li Zhi guided the blacksmiths from beginning to end to build bearings.

The first is to cast the steel ring, which is very simple, and the molten steel is formed by casting the molten steel with a mold made of sand. However, in order to reduce the porosity honeycomb on the steel, the blacksmiths used the cast steel rings to make iron molds in turn, and then used the iron molds to cast the steel rings.

Then a round steel rod is burned red and soft, and a small section of steel is cut out on a simple cut-off device as the raw material for the ball.

Put the raw materials of the balls in a furnace and heat them until they are red-hot, take out the raw materials one by one, put them on a steel block with a semi-circular hole, use a steel stick with a semi-circular hole on the ball raw materials, hammer the steel rod with a hammer, and squeeze the raw materials into a spherical shape.

Once the rough balls are obtained, the balls are screened with multiple ball sieves to remove balls that are too large or too small. The balls are then deburred and polished with a grinding wheel and grinding disc. After obtaining the smooth ball, the ball is tempered and heated, and finally poured into the hot oil to quench to improve the hardness of the ball.

After the balls are done, the balls are arranged in a row into the outer ring of the bearing, and after the inner ring of the bearing is installed, the balls are slid to different positions, and the balls and the inner and outer rings are connected into one and will not fall off.

Finally, the cage is made of iron sheet, fixed with steel nails, and the balls are wrapped from both sides, so that the eight balls are evenly distributed in the steel ring and will not collide and rub.

Because of the physical reference, the blacksmith made the bearing of the cottage in half a day. Because of the first build, plus there is no special tool, the efficiency is a little slower, and so on the future large-scale production, the special abrasives to get out, the production of a bearing for a few minutes, Chen Zijian with some residual temperature of the cottage bearing, the first feeling is rough, the surface of the ball is not too smooth, the cottage bearing does not rotate as smooth as the genuine product, the cottage bearing can only move by hand, let go and stop immediately, this thing will be put in the future, and only those who pick up garbage will pick it up and sell it on the road.

However, since the bearing is built, the rest is to be transformed, such as immediately creating a passing bearing is impossible, now Chen Zijian needs the quality of the bearing is not high, now this is acceptable.

Chen Zijian said, "Okay, come here, and give you a reward now." ”

Hearing that there was a reward, the eyes of the ten blacksmiths lit up, who didn't know that the chief's reward was huge!

"I won't meddle in the bearing matter, I just want the finished product."

Everyone looked at each other and didn't understand what Chen Zijian meant.

Chen Zijian said, "The bearing thing belongs to the private enterprise, now I want 50,000 bearings, one or two silver to buy one, I don't care how you build it, anyway, if you want to make money, you find your own way." Whether it's an individual build, or a partnership, in short, I just want the finished product. ”

Chen Zijian does not plan to keep the bearing thing secret, this thing blacksmith knows the principle at a glance, there is just no demand before, I can't think of it, the bearing is a branch of the primary industrial system, ten blacksmiths are the seeds planted by Chen Zijian, maybe private enterprises can breed a few bearing kings in the future.

This is somewhat similar to the previous fishing, Chen Zijian only needs fish, he doesn't care how you catch fish, anyway, you can catch fish Chen Zijian left the silver, and the same is true for the current bearings, let these ten blacksmiths figure out their own way, as long as they can create the bearings, Chen Zijian will buy them.

As for how to improve the quality and quantity of production, it depends on their ability, and the seeds are planted to see their future operations.

Blacksmiths want to make money, and they don't want to try to improve the quantity and quality of bearings, this doesn't need Chen Zijian to blow, the motivation to earn silver will spur them.

Chen Zijian looked at the blacksmith who was still a little confused, so he had to say in detail, "I mean, you go back and build your own factory, uh!" workshop, and then find a way to build the bearings yourself, and then buy the bearings to me, I want 10,000 bearings in the early stage, and then there are 50,000 orders, you want to make a lot of money just work hard! ”

After saying that, he left with his hands behind his back, and he was considered to have completed one thing, and asked the carpenter factory to stop producing the trolley, and at the same time took the five bearings that had just been produced together, and asked the carpenter to find a way to transform the new trolley.

Received Chen Zijian's order, see the use of bearings, the wood factory will understand the truth, bearings can greatly reduce the strength of the transport team, increase the weight of goods, how to transform the new car wood factory can be solved, no need Chen Zijian to meddle in things, an hour later, the director of the wood factory personally sent the new trolley, compared with the previous trolley, increased a bearing.

Chen Zijian: "Okay, in the future, it will be produced in this way, the front one does not need to be produced, and the bearing is not redundant now, but you can produce other components first, and then the bearing can be installed directly." ”

Chow Tai Fook repeatedly said that he would do things according to the chief's arrangement, and he was an ordinary carpenter, but Chen Zijian arranged to manage hundreds of carpenters, which can be described as infinite.
