Show the sword, start from the guerrillas

Chapter 471 Chapter 470 Although the output is not high, the confidence is high

If you think of it, just do it. Li Yuexuan took out some yellowed books which contained ancient waterwheel manufacturing technology. It was unclear where the comrades got it from.

"These are some technical books we can find on waterwheel manufacturing. There are also many ancient technologies in them, which we need to refer to. You are all experienced fitters, and some of you are also skilled carpenters. I think this waterwheel problem will not be difficult for you!"

"What we need to consider now is to connect the rifling cutting machine to the waterwheel, and then use the waterwheel to drive the transmission shaft to produce rifling. Comrade Huang Xin should be able to do this, so let's leave it to Comrade Huang Xin. What I'm going to talk about next is the focus of this meeting."

"These are some of the data I have recorded recently on the production of bullet shells, including molds and other data! Now I want to put forward my request, which is to use this data to design a machine that can repeatedly forge with the help of hydraulic power. I also want the force of this machine to be just enough to produce bullet shells."

"Have you seen the one that uses a water wheel to pound rice? It uses that principle, and then the punch for pounding rice becomes the hammer head, and the rice mortar below becomes our mold, allowing the machine to pound repeatedly."

"I have two ideas. The more complicated one is to add a transmission device to the mold below, which can continuously transmit in one direction as the hammer hits, so that each hammer can hammer the shell on the mold once, and the final hammer will finalize the shape, and the finished product will come out. Of course, this will be very complicated, but a set of machines can complete the production of shells, saving labor."

Li Yuexuan came up with this first idea by referring to the shell forging process of bullet production machines. He proposed it to see if his comrades could solve it. Of course, he did not expect to see results in the short term, so he then proposed the second idea: "The second idea is much simpler, that is, it does not require transmission, and each group of hammers is only responsible for one process."

"What you need to design is how many hammers are needed to complete this process after the copper plate and the mold are placed, and then stop the equipment and send it to the next process."

"In this way, you need to design as many sets of hammering waterwheels as there are processes for a shell. Workers also need to stop the machine frequently in the middle to put the forged shells into the next set of hammering equipment while adding new materials to the first set of hammering equipment. The advantage of this is that the equipment can be made quickly, but the disadvantage is that it takes up a lot of manpower!"

"But no matter how we do it, it can free the workers from the repeated hammering, and the fixed hammering force and frequency can also achieve greater precision!"

"So, the design plan has been given to you, and the realization of this plan depends on your ability! The meeting ends here. Except for Comrade Huang Xin who will lead the carpenters to produce water wheels and rifling machines, the rest of the comrades will be responsible for figuring out the forging process of the shells! By the way, to facilitate your research, I have drawn some of the parts about shell production in the drawings of the bullet production machine that I remember, and you can refer to them."

Li Yuexuan gave some drawings to the technicians and left. The rest was up to the technicians. Now no one asked where Li Yuexuan got his technology from, and there was no need for him to hide it. Anyway, Li Yuexuan's performance was there. The bullets had been made, and it was normal to have seen the bullet production machine before. That's right, although the efficiency of shell production was very low, at the end of the day, there were more than 1000 scrap shells than finished shells, but there were qualified products after all!
The current number of bullets produced may sound embarrassing, but Minister Zhang is not disgusted at all, and even seems very happy. More than 150 people work hard all day and can only produce more than 500 qualified bullets. This efficiency is really not good.

But Minister Zhang was happy that the Eighth Route Army finally didn't have to rely solely on captured ammunition! He also calculated for Li Yuexuan that if he calculated 500 rounds a day, 15000 rounds of ammunition would be available in a month, enough to be allocated to a basic regiment for combat! According to the size of the basic regiment of 750 people, this means that each comrade can be allocated 20 rounds of ammunition!
In one month, a basic regiment was armed. Minister Zhang felt that he could wake up laughing even in his dreams! Moreover, the basic weapons of this basic regiment were 600 Type 20 rifles, 12 semi-automatic rifles, 6 Qi-pulling light machine guns, 3 grenade launchers, 2 heavy machine guns, and 82 Type mortars. The combat effectiveness was not weak.

That's right, Minister Zhang has intentionally or unintentionally increased the number of semi-automatic and assault rifles held by the main force and the basic regiment. The basic regiment did not score any points for assault rifles, but it did have a quota for the Qi Lali light machine gun.

Strictly speaking, the production efficiency of the headquarters arsenal is more than enough to equip a basic regiment per month, and can also provide the main regiment with more than 100 assault rifles and light machine guns. Other heavy mortars and 82 mortars can also meet the needs of several main regiments.

This production efficiency cannot be compared with that of the Russian family, but Minister Zhang and the Chief of Staff who comes to check every now and then are all extremely satisfied!
Moreover, Minister Zhang and the workers in the arsenal are all full of confidence, thinking that these production capacities are temporary and will get better and better in the future! This confidence comes from the continuous production of guns and ammunition, the full storage of raw materials in the warehouse, the continuous delivery of food and supplies from various troops, and Li Yuexuan himself, who usually does nothing but wanders around.

Invisibly, Li Yuexuan's identity has changed from a pillar of support on the battlefield to a source of confidence for the arsenal. It seems that with him here, there is no problem that cannot be solved.

July ends and it’s August, August ends and it’s September, and in the blink of an eye another two months have passed.

At this time, solid fortifications had been built on the arsenal's "One Line Sky" position. The bunkers were built with thick bluestone and mortar, and it was said that cement captured from the Japanese was also added.

Inside the Yixiantian, there are also some fortifications made of reinforced concrete, which are connected to the positions outside the Yixiantian through the traffic trench that was dug hard on the top of the Yixiantian mountain.

These two communication trenches took a lot of effort from the engineers! They dug up the half-meter-thick soil layer attached to the upper part of the cliff, then burned fire and poured water on the rocks, and continued to dig down, and they dug a trench three meters deep and one meter wide on the cliff, with a bend in the middle.
