In the equipment department, Song Changping took his artillery production team to sit down. Pen "Fun" Pavilion www.biquge.info

After Song Changping became independent, Song Changping only brought the artillery production team that had followed him before.

Standing in front of the blackboard of the equipment division, Xiao Ming drew the structure of the flintlock pistol.

Both types of firearms, whether they are arquebuses or flintlock guns, are smoothbore guns, with the only difference being the way the gunpowder is fired.

The arquebus is very simple, basically the same principle as the artillery, as long as the barrel is obtained, this technology is not a problem for Song Changping and others.

It's just that for Xiao Ming, there is no need to reproduce arquebuses, and arquebuses can't play a good role in dealing with cavalry in the field, and the amount of two shots in three minutes, just like the three-eyed musket of the Guanning Iron Cavalry at the end of the Ming Dynasty, is only two bullets in battle, and the rest is hand-to-hand combat, and once the arquebus is extinguished, it needs to be re-ignited, at this time there is no difference between the arquebus and the burning stick.

The flintlock pistol avoids the situation that the arquebus goes out when firing, and the stability is higher, which is why the flintlock pistol quickly eliminated the arquebus.

"In general, the outside of the bolt of the flintlock pistol is divided into four parts: striking iron, main spring, buckle spring, and gunpowder pool, of which the striking iron is used to fix the flint, the main spring provides power for the striking iron, and the buckle spring is the iron piece hit by the flint, and the powder pool is used to pre-load a small amount of gunpowder to ignite the gunpowder in the barrel."

And there is a trigger in the bolt, the core, the blocking iron and the blocking iron spring, the buckle reed, the inner main spring, in which the trigger is used to fire, the core maintains and releases the power of the main spring, and transmits the power to the striking iron, the blocking iron is when someone pulls the trigger, meshing the core, and then releases it, the buckle reed is fixed and connected to the cover of the buckle spring on the gunpowder pool, so that the flintlock gun can resist the wind and rain, in general, this principle is that when the trigger is pulled to gather a strong force on the main spring, the blocking iron will mesh with the core. When the trigger is pulled, it pushes the stopper iron forward until it can release the core, causing the striker to push the flint forward. ”

On the blackboard, Xiao Ming pointed to the structure of the flintlock pistol and explained it little by little, and Song Changping and other craftsmen memorized it carefully and engraved all the structure of the flintlock pistol in their minds.

At the same time, they noted the dimensions of the various structures of the flintlock pistols on the blackboard.

In Song Changping's view, the forging of the small parts on this shot is a very troublesome thing, whether it is a striking iron, a spring, a movement or a trigger.

After explaining the entire structure of the flintlock pistol, Xiao Ming said, "Now you can raise the difficulty. ”

"Your Highness, it's still a question of this spring, how to make steel elastic?" Song Changping raised the most important question.

In his opinion, if the spring could not be made, the flintlock pistol could not be produced.

At this time, Xiao Ming laughed, and he said, "Originally, it couldn't, but now it's okay." ”

"Oh, why?" Song Changping said strangely.

"Do you know why this king is looking for tungsten ore and has not started to produce flintlock pistols for a long time?" Xiao Ming asked.

Song Changping shook his head.

Xiao Ming said at this time: "The barrel is only one of the problems, you can make the barrel by hand, but at that time you can only produce arquebuses, not flintlock pistols, because there can be no spring steel at that time, because spring steel needs the element of carbon manganese to produce, even if there is a barrel at that time, it is not much use, but will waste a lot of manpower and material resources." ”

After a pause, Xiao Ming said: "So now you know the reason why this king has always been paranoid about tungsten ore, not only for the knife, but also for the material of spring steel." ”

Song Changping nodded slowly, as craftsmen, they naturally knew that the method of using iron rolling could make the barrel, but the handmade barrel also had disadvantages, that is, the barrel created by different craftsmen would have errors and was very time-consuming.

The structure of the flintlock pistol was all explained, and Xiao Ming asked Song Changping to give a task to his team.

Now that there is a lathe, it is necessary to carry out assembly line production, and the precision scale is available, and the standard is formulated for the craftsman to divide the labor to manufacture different parts and finally assemble them, so that the production speed of the flintlock pistol can be increased.

After all, he could not compare with the Western countries, or even the Japanese state, with the old method, because his fief was only 600,000 households, and all his labor came from a limited number of slaves.

In addition to increasing the degree of mechanization, it is simply impossible to compete with its own enemies.

"Your Highness, I'll be in charge of this spring steel." Song Changping took the initiative to provoke the most difficult part.

Xiao Ming showed a look of praise, and he said, "In that case, let's go find Zhang Liu." ”

Let the members of the flintlock pistol research team be responsible for their own accessories, Xiao Ming and Song Changping found Zhang Liu.

Nowadays, the molds of boring machine tools, milling tools and drilling machine tools are prepared, just waiting for tungsten ore to be extracted.

"Prepare some charcoal, put tungsten ore powder and charcoal together and calcine them at the same temperature as ironmaking." In the backyard of the Instrument Division, Xiao Ming found Zhang Liu, who was discussing problems together.

After receiving Xiao Ming's order, Zhang Liu and the craftsmen immediately took action, and they waited to extract tungsten.

Based on the current scientific and technological conditions, Xiao Ming can only use the carbon reduction method to extract tungsten, in the historical data, in 1783, the Spaniard Depurya discovered wolframite, in the same year, he used carbon to reduce tungsten trioxide for the first time to obtain tungsten powder, and named the element.

Therefore, it is feasible for Xiao Ming to use the carbon reduction method, although the purity of this method to extract tungsten is not high, but it is more than enough to use in this era.

It will even make his Qingzhou's lathe technology stand shoulder to shoulder with the West in one fell swoop, or even surpass.

Tungsten ore powder and charcoal were mixed and poured into a blast furnace heated by a regenerative chamber, and Zhang Liu, Xiao Ming and others began to wait.

An hour later, waiting for the blast furnace to cool, Zhang Liu took out the mixed powder through the reserved opening, and some silvery-white particles came out of the black powder.

Although these particles are very small, they have proven that tungsten has been successfully extracted by charcoal reduction.

"Your Highness, are these silvery-white particles tungsten?" Zhang Liu asked, when mixing materials, he had never seen this kind of silvery-white particles, and the only answer was that this kind of thing was tungsten.

Xiao Ming nodded, with joy in his eyes, this is another technological breakthrough in Qingzhou, he said: "That's right, this is tungsten, now we can produce tungsten steel." ”

Zhang Liu and the other craftsmen had a thick smile on their faces, and he immediately said: "You guys go and get a sieve to sieve out the tungsten, and then take some charcoal to continue to extract tungsten." ”
