Chapter 207: Armor-Piercing Cone

Zhang Shu looked at the army, and joined the army: "Changshi, in fact, you can apply for the transfer department, can the class affairs of 100,000 arrows be offset by 20,000 arrows?" That's a lot better than that! ”

Zhang Shu was noncommittal, turned around and asked, "Shi Lao, this is ...... Armor-piercing cone, how much is it worth? ”

Shi Fu smiled and said, "This...... If it is true that as he said in the army, 100,000 becomes 20,000, and the business will not be done. ”

Except for Su You, everyone was puzzled: "But why?" ”

Shi Fu said with a smile: "To make this kind of arrow, you need to produce a large number of tools, molds, and abrasives, which is called early investment; The iron material, coal material, bamboo lacquer silk feather behind the back, called the later input. The profit of the business is mainly generated by the later input, if the amount of production is too small to offset the early investment, then we will lose money. ”

Zhang Shu suddenly said: "It makes sense, then do you have a response charter?" ”

Shi Fu said: "We calculated that if we produce 100,000 armor-piercing cones at one time, we can control the price at 200 yuan a piece, and if there is an order for 200,000 pieces, we can press it to 150 yuan a piece; If it is more than 300,000 yuan, we can accept it for 130 yuan! ”

Joining the army thought that this kind of arrow would cost at least three or four hundred wen, but when he heard that it was so cheap, he couldn't help but stand up from his seat: "Is this true?!" ”

Zhang Shu beckoned to join the army: "Sit down first, in this way, it is no longer a county matter, this matter must be handed over to the Transit Division, and it is up to them to decide." ”

Joined the army and said: "Long history, this is a military feat!" Give me the arrows, I'll set off now, and I'll borrow the family's water-skimming boat to Chengdu! The results will be known tomorrow. ”

Zhang Shu turned to Shi Fu and said, "Shi Gong, how long will it take to build this arrow?" ”

Shi Fu said with a smile: "If it is 300,000, the Su and Shi families can be delivered within three months." ”

Zhang Shu couldn't sit still at this time: "In this case, please join the army and go to Chengdu for a business trip, wait, wait for me to repair another book, and you go directly to see my father." ”

The next day, the news of joining the army came back, and the transfer department agreed, 500,000 armor-piercing cones, and the price was 150 wen each!

A large order of 75,000 times!

Shi Fu and Su You looked at each other, didn't they say that they could control it within one hundred and thirty Wen?

Zhang Shu pulled Shi Fu into the inner room, the two muttered for a long time, and after coming out, Shi Fu smiled all over his face: "It's still Zhou Xiang that Bachelor Zhang is worried about, and he almost lost his mind this time." ”

Zhang Shu arched his hand: "It's hard work, but the quality must be able to withstand the random inspection sent by my father." ”

Shi Fu smiled: "That's nature. ”

Coming out of the county office, Su You asked, "What's the matter?" Mr. Zhang is a notoriously understanding person, how did he become so confused? ”

Shi Fu shook his head with his hands behind his back and exclaimed: "So people can be bachelors, this arrow must be set at this price, and the surrounding bow and arrow workshops will have a way to live, this is one of them; If the price is too low, if Bianjing feels that there is a head, then there will be no arrow left in Sichuan, which is the second; The focus of the Great Song Dynasty's defense was the north and the northwest, and this was the purpose of Mr. Zhang's transfer division to replace the arsenal, not to add glory to the Huahua troops in the DPRK and China who could only proofread. ”

Su You understood, sure enough, he was born in a plan, and he was accustomed to using economic means to solve political problems, and by raising prices, he left the arrow in Sichuan, and then radiated to the northwest, and finally considered Bianjing.

It's very reasonable, but in the eyes of many Great Song Masters, I am afraid that I will be accused of having no father, so I can only do it but not say it.

As for the extra fraction, hello, hello, hello everyone, it's a little bit of money.

Shi Fu turned around and said to Su You: "My Shi family was born in martial arts, and I have been in it for generations, where can I really get rid of it with the Great Song Dynasty?" Disciples of the Shi family, not only have to fight with a knife on the battlefield, but also suffer from taboo side eyes, and never get ahead, in your words, it is called high risk and low return. ”

"Now that I have this opportunity and transferred to the production of weapons, the lives of my Shi family disciples have really been saved. Mingrun, such a great grace, should be courtesy from the old man. ”

Su You hurriedly jumped to the side: "Don't be, why don't you talk more and more?" Can things still have anything to do with this? ”

Shi Fu smiled: "Say you're smart, that's really smart, but sometimes why can't you turn a corner?" If you are an official family, can you let a family that not only has a foundation in the army, but also controls the production of powerful weapons? From now on, as long as my Shi family continues to make good weapons, the disciples of the Shi family will get out of the battlefield step by step. ”

"Although the impact of this on the army is separated by a layer, the master-slave relationship has changed! From the past, the Shi family begged the military to take care of Erlang, to the military begged the Shi family to provide high-quality products, hahahaha...... Let's go, go back to drinking! The old man is going to get drunk today! ”

Su You followed behind in a daze, and Lao Tzu said why the Shi family was so attentive to me, it turned out that he had already figured it out!

Demons! It's all demons! None of them are fuel-efficient lamps!

……

The manufacture of new arrows is no longer difficult for the technical reserves of Kelongli.

The arrow shaft is the waste left over from the wells used to build the derrick and the hoistway.

The bamboo tube is cut into bamboo strips, and then the skin and core are removed with a grinder, leaving only the bamboo flesh.

Turning bamboo strips into round bamboo sticks is a craft that has matured as early as the Land Temple, and the bamboo nails used to build houses and make bamboo furniture are pulled out on a stool with a blade.

Now that the specifications have been uniformly adjusted, the tools have been handed over to all households in Kelongli, and the farming season is just right for work, and men, women and children can do it.

Fifty households, each of them paid a hundred arrows every day, which is five thousand. Occupy the farm for three months, and do not delay anything.

After the arrow shaft embryo is made, it is bundled into bundles, steamed in a pot, and then sent to a drying room with hot exhaust gas from the furnace to bake, and the arrow shaft embryo can be automatically straightened.

The next step is to cut on the sawing machine to get a uniform size shaft.

Spray tung oil with lacquer and send it to a paint chamber that maintains humidity for complexization and drying, forming a paint film that is convenient for moisture prevention in the future.

Compared with the shaft, the arrow shaft is simpler, first rolling an iron wire rod with a round groove, then gradually rolling into a thin iron bar, and then cutting into a small iron cylinder with a grinding wheel saw blade.

The babies placed the soft iron cylinders one by one in the mold pit of the high-manganese steel stamping die. It is fed under the forging machine and forged with a die.

After a hammer forging, the abrasive tool is closed, taken out and opened again, and it is a plate full of unified standard arrows with tails.

Use pliers to clamp the iron sheet around the overflow, grind it coarsely on the belt grinder, and send it to the carburizing box for carburizing, and one box can process thousands of arrowheads.

Today's good arrows, the arrow feathers are eagles, followed by swans, then bustards, and geese are the second.

Su You was too lazy to work hard, so he used the goose feathers and duck feathers in the dragon, and changed the arrow feathers from double feathers to three feathers, which easily solved the problem of insufficient material strength and size, and the stability was much better.

However, with the help of a small machine, a small rocker that can divide the circumference into three parts, with an indicator line, makes it easy to determine where the arrow feathers are pasted.

Then wrap the high-strength silk thread of the Sujia weaving workshop to fix, insert the arrow, install the string card, and an arrow is completed.

After the arrow is carburized, it is necessary to rotate and polish on the pedal workbench to remove surface impurities and polish smoothly.

The small crank can also come in handy here, where arrows can be clamped and the three-edged arrow tips can be pushed out with a belt grinder on the workbench.

In fact, Su You felt that this step was optional, and later generations had not heard of a three-edged bullet.

However, this baby was misled by the slow motion of later generations, the arrow does rotate, but it is caused by the inabsolute uniformity of the tail feathers, and the high-speed rotation of the bullet is two principles.

However, fortunately, he was more cautious, and there was no large number of experimental data to prove it, and the current process was also reserved for the habit of taking care of the Song people.

The important thing is that the process flow is simplified, and the introduction of a large number of high-precision processing tools makes the operation simple, and it only takes two days to train the manual operation of the fixed process.

The division of labor and cooperation of the assembly line made the efficiency extremely high, and Kelongli soon became a large workshop with a daily output of 6,000 armor-breaking cones.
