Chapter Ninety-Six: Stamping

Su You couldn't help but have a black line in his head: "Brother, don't make trouble!" It's called artificial incubation! ”

Shi Tong pouted: "Spending so much firewood, and deliberately building a house, just to hatch dozens of eggs, it's really ...... The egg hurts. ”

Su You didn't say anything yet, Shi Wei was first dissatisfied: "Do you want to say that Brother Xiaoyou did something wrong?" ”

"I ......" Shi Tong really wanted to say, but the number of times he was slapped in the face was a bit much, so he was just embarrassed.

Shi Fu smiled: "Don't say so much, let's put the kiln on the wall first." ”

There are two kilns, both of which are not large, and belong to experimental-grade equipment, one is a steamed bread kiln, which can fire porcelain and pottery, and the other is a graphite crucible kiln, which can smelt metals and other substances that require high temperatures.

This design is very reasonable, the flue is arranged with pipes, and the remaining heat energy can be used to pre-heat the inlet air, and this measure alone can increase the furnace temperature a lot.

The asbestos has also arrived, the fiber is of high quality, and it should have been treated, which was quickly sent by Ah Hoard.

There are also hundreds of liquor income, but the Erlin Department has no currency, and directly uses bronze to offset the account.

General Huaiyuan is wealthy, and one pound of bronze is worth eight hundred yuan, plus some of the proceeds are also distributed to Su You, a total of three hundred and fifty pounds of copper.

In addition, countless skins were attached, which can be regarded as a return gift from the general to thank the treasure knife, which is a human exchange.

It seems that this transaction, the second forest department is making a lot of money.

There are also various minerals collected by Ah Homi, which is also the requirement of Su You.

The two small kilns are not far from the canal, and the water power should be fully utilized.

The friction of the ceramic roller bearing is extremely small, and under the same water flow and dynamic conditions, the efficiency of this waterwheel is not comparable to that of other mills in the Great Song Dynasty.

The children are very familiar with the drawing, and they command the workers to paste a thick layer of asbestos on the inner layer of the two small kilns, and Su You and Shi Fushi are studying another equipment - punch.

It sounds lofty, but in fact, the main component is a long iron shank, with a cast iron gear on the head, the gear shaft is fixed on the left side of the U-shaped iron frame, and the long iron handle is also on the right side of the iron frame.

Another gear rod engages with it, and the other end is on the right side of the U-shaped iron frame, pressing down on the handle, and the gear on the handle head carries the driven gear rod to produce downward displacement.

At the end of the gear rod, on the inside of the U-shaped iron frame, there is a stamping rod sleeved in a sliding round hole, and the gear rod will exert pressure on it.

This is a terrifying force because it is equivalent to two levers, the power arm is the long handle and the gear bar, and the resistance arm is the radius of the driving gear and the length of the rivet to the stamping rod connection, in the ratio of ten to one and eight to one.

Therefore, theoretically speaking, the pressure on the head of the long iron shank is magnified eighty times!

Fifty pounds of pressure, after the exercise, it becomes the power of four thousand pounds on the punch!

The punch was replaced with a punch and a seat, and Shi Tong turned the lead screw handle to adjust the height of the base.

Su You instructed Shi Fu to install the power transmission mechanism, which was actually a simple cam that turned the rotation of the water wheel into a straight up and down movement of a long iron rod.

Both the base and punch are detachable, with a bayonet on the top that can be used to place various stamping dies.

Let's start with the simplest, with a dozen hemispherical pits on the seat, including on the punch plate.

Shi Tong put a small piece of iron rod in each pit and shouted to Su You, "Master, try it!" ”

Su You asked Shi Fu to move the wrench, and the cam was driven by the gears on the shaft of the waterwheel and began to rotate.

Then the connecting rod was driven by the cam again, and the punch was lifted first, Shi Fu inserted the mold bed into the groove, and the punch soon fell again, completely ignoring the small iron in the pit, and easily pasted it with the mold bed.

When the punch rises again, the small pieces of iron on the mold bed have all turned into shiny beads, and there is a thin circle of redundant material on the side, like small Jupiter.

Shi Fu raised the clutch, stopped the movement of the machine, and rushed to Shi Tong with the agility that the elderly would never have: "Is it done?" ”

Shi Tong was speechless: "It's too powerful, the iron ball is like cement." ”

Shi Fule couldn't do it: "Oil baby, with this thing, can you get the ball bearings you said?" ”

Su You counted his belongings with his fingers: "Now that we have stamping technology, heat treatment technology, lathe cutting technology, ball bearings should be no problem." ”

Shi Fu looked at the sky and pondered: "It's only used to make balls, it seems a bit of a waste?" ”

Su You laughed and said: "This thing is tailor-made for your Shi family, put a piece of copper in it, boom!" When it comes out, it's a copper plate! ”

Shi Fu was stupid, and according to the speed of the rise and fall of the punch just now, he made the action of sending copper sheets: "Bang! One...... Boom! Two...... Boom! Three...... My god...... That's a few hundred dollars......"

Su You was too lazy to manage the Shi family's father and son drooling and became stupid, and took the iron ball to check the error between the upper and lower hemispheres, and the accuracy of the micrometer was 0.1 millimeter, which was still a little larger.

However, this is only the beginning, and the next step is to use pliers to remove the excess cutting edge, and then throw it into the ball mill, so that countless iron balls roll and rub against each other, and finally the perfect ball can be obtained.

However, the error between the beads may still be a little large, which is also a matter of no way at present.

Putting aside these thoughts, Su You looked at the ditch flowing down from the mountain: "There are still more waterwheels needed......

Shi Fu was already stimulated by the great prospect of stamping to make bronze objects: "How much?" Oil baby, just open your mouth! ”

Su You said with a smile: "Forget it, let's take it step by step, just follow the principle of this punch, first make a few manual stamping machines, and change the punch to a steel blade, which is a cutting machine, which can be used by the bookstore over there." ”

Shi Fu shook his hand: "Don't don't, you can design a forging machine for me first, you can make iron, this thing saves labor!" ”

This requirement seems simple, but in fact, the mechanical principles involved are quite different.

Later forging machines are impossible, and only spring hammers can be realized at present, and they are the most primitive leaf spring hammers.

A cantilever is made of spring steel plates, and connecting rods are hung at both ends, and a square hammer is suspended from the two connecting rods.

The top of the spring steel plate is driven by an eccentric wheel, which is responsible for the lifting of the hammer head.

The spring itself is responsible for cushioning the drag of the forging, while also producing a short-range repetitive action up and down, simulating a continuous hammer blow.

The production of spring steel plates is no longer difficult, in fact, it is a very simple steel tempering treatment problem.

After drawing the drawings of the forging machine, Shi Tong Shifu took it and ran, this design was explained by Su You while drawing, and the father and son boasted that it was wonderful.

Looking at the back of an old man and a young man who were far away, Su You touched his nose: "Wonderful fart, oil hammer is king......"

However, before there was no rubber, it was still quite difficult to design a steam hammer and a hydraulic hammer by only relying on brass leather ring sealing.

The next few days is to improve this watermill room, Su You led everyone to learn and use it at the same time, and transform the power clutch to be more perfect.

Soon the first group left, and Li Lianzhu came with the second group.

At the same time, iron sand, coke, graphite crucibles and sawing machines were also brought.

Equipped with an air pre-heating system, a strong blast system and an asbestos insulation inner wall, the smelting effect immediately increased by an order of magnitude, and Su Oil estimated that there was no problem with 1,500 degrees.

The heating chamber and the reduction chamber are separated and strong oxygen can be fed, while the reduction reaction is carried out separately by the carbon and iron ore powder in the crucible.

Now it's a pure carbon black, this oil is ready to be cleaned after carbonization with pine smoke and sulfuric acid, and now, replace it with black coal ash adsorbed on the chimney.

Then this matter must be mobilized by the children in the village, so the villagers made a fuss again, and they are getting more and more crazy! Xiaoyou is now leading the babies to the beam!

The effect of soot is certainly not as good as pure carbon, but it is also much better than the previous toner, mainly because it contains almost no sulfur, so the resulting manganese steel has excellent properties.

Su You's positioning for himself, in the future, this will be a research base, an experimental base.

As for the problems of mass production and quasi-industrialization, it is left to the nerves of several major families to make their own laboratory-grade products, which are worthy of their offerings and dividends.

The sawing machine is connected to the waterwheel, and the efficiency is great, wooden squares, wooden strips, wooden planks...... Soon piled up next to the watermill house.

Every day, many folks come to see the strangeness, and those who are curious have to try it out.

It happened to enter the winter leisure, and now Suyou is not bad for money, so simply recruit the villagers, let's start work and renovate the canal!

First of all, the mountain pond was built at the inlet of the canal to store water, and the diversion of the previous stream water was redistributed, and most of it was diverted into the canal to increase the power of the waterwheel.

At the same time, it is necessary to build sediment sedimentation tanks and reservoirs in different sections of the canal, plus the addition of watermill houses and sidewalks along the way, and the amount of work is also quite large.

After seeing the power of the waterwheel sawing machine, Bagong heard that Su You would transform the waterwheel house into a mill and an oil mill in the future, and immediately took the initiative to become Party B.

The men who can make each family pick the fifty, Xiaoyou, you have 100 yuan per person per day plus two meals, this work does not need to be cheap outsiders, we have it for you!
