Chapter 252 The solution to the marriage problem of Comrade Hancheng
For important transportation lines, the bombing intensity of the national army is quite strong, especially the transportation arteries. On the contrary, this small place in Hancheng did not attract enough attention, which gave Hancheng a time to organize forces to attack Japan.
The time for the joint public relations imitation of the Type 4 75mm anti-aircraft gun. For the poor Eighth Route Army, this was an anti-aircraft gun that could directly threaten aircraft. It was also the first domestically produced anti-aircraft gun.
The most important point and the biggest advantage is that it can directly attack the Allied heavy tanks head-on. Especially for some bridges and bunkers that are difficult to capture, continuous attacks can directly destroy them. More importantly, this
The anti-aircraft gun is not as mature as other artillery guns and has been officially put into production, because it has not been produced in Northeast China for a long time, so many technical parameters are not as complete as other artillery guns, but this one is still very complete.
"Now, we have to get the two most important things done first. One is the supporting frame and the table. The Japanese numbers are very detailed. Here, they used three different specifications.
Gears, what we have to do here is to make these three types of gears and ensure sufficient hardness!"
For these technicians, Han Cheng still has a headache to explain. If you tell them to make it according to the size, they can make it, but if you ask them what kind of strength and hardness you want to make, they have no concept in their minds. But
It is actually quite difficult for Hancheng to implant industrial ideas into these people's minds. The simple thing is to make them harder and more wear-resistant.
As for the gun barrel, it’s actually not too difficult. Mainly because Han Cheng is watching, because the material formulas are all available. The only thing missing is experience. These people don’t know how to read the furnace temperature. Different furnace temperatures are used to load materials.
The order cannot be wrong, and the temperature cannot be wrong. Today's steel plants either look at the temperature from the sensor, or old workers use color cards to judge the furnace temperature. Now this cannot be compared with later generations. There is no such thing, but there are people who don't work.
.
"Then what should be done?"
When the people below asked about this matter, Han Cheng's head hurt. Ordinary workers gave him instructions on how to process it, and basically there would be no mistakes. But gears are still very technical, and there is no good method now.
, the only way is that Hancheng modified a small forging hammer, installed a special tool on it, and processed it directly. It can be regarded as a semi-automatic gear shaping machine.
"We first need to forge a steel blank of suitable size, just use our small forging hammer. Different gears require different tools. Among them, different gears use different ingredients. You must pay attention to the production.
Things should be marked well. If one is mistaken, the tool will be damaged at least, and people will be in danger at worst."
Han Cheng had to explain every step of the process completely, but Han Cheng finally realized how difficult it was for scientists in the early days of the founding of the People's Republic of China. If he had the right talents, he wouldn't have such a headache. There is also a transmission shaft that has not yet been made.
Well, this technology is really cutting-edge, and we still need to think of a good way to solve it.
Industrial production is like this, there is no way. Donkey carts are used for transportation in the workshops. Now there are no trolleys or anything like that. It can’t be moved by people alone. So when the entire factory was built, the aisles were designed
It is very wide, and the purpose is to facilitate transportation by donkey carts. However, it is also a bit inconvenient, that is, the distance for people to carry it is large, but there is no other way.
"Okay, you guys go down here and get familiar with it first. Don't start yet. Wait until I finish the test one by one and you will get started. It will be harmful to you to get started now."
Building a cannon is not an easy task, especially after all the explanations for this circle are completed, Han Cheng can take a rest. The people from the security office are also asked to watch the machine, and no one can get close to touch the machine, especially this one
What should we do if something goes wrong? There are two sources for the steel that has been produced at the factory, namely the production of the newly built steel plant and the blast furnace. The next step will be to stop the output of the blast furnace.
Converting to the output of steel mills, because the corresponding sand molds are already fully available, steel materials of any size can be transported to different types of forging machines through different roads, guaranteed to be the first time.
There is a human-powered crane next to the large forging machine, which is used to transport large steel blanks. All processes in the factory cannot guarantee complete automation, and human transportation and handling are still the mainstream. Hancheng has also rushed to make a crane for this purpose.
There were gloves made of linen and helmets made of wicker. However, due to material difficulties, two people could not get a pair of gloves. It looked like these gloves would last a long time.
"Master Han, look at this!"
After returning to the armory, Han Cheng saw Na Ye waving to him with a mysterious look on his face.
"Is this an enamel jar?"
"Yes, my hands are itchy and burning today. Don't tell me, this thing is much easier than burning porcelain! I can basically figure out what you want to burn, and what color you want, I can basically get it.
."
I have to say that having an old man in a family is like having a treasure. I took an enamel jar and polished it for a few days to solve the problem. Of course, the enamel jar cannot be saved, and destroying it is definitely a necessary method.
"Oh, you are really good at this. How long did it take you to finish all the enamels sold by foreigners?"
"We broke it open and saw that it was just a layer of ceramics on the outside. I knew it was a layer of ceramics wrapped on the outside and burned on the inside. The more troublesome thing is how to make the ceramics stick to the iron and the thickness should be consistent. But this
Why is it so hard to defeat us? This can be solved easily!"
If nothing else, the old man is really good. At least the master and apprentice are in trouble now. The old man has also started to find a wife for his three fools, and by the way, he has also started to talk to Han Cheng. The three fools are okay.
, find a free time to meet with your younger wife and older daughter-in-law, and if you meet someone you get along with, just see them often. Once the relationship becomes deeper, it will become a matter of course.
Things are not going so smoothly in Hancheng. It's not that I don't introduce him to Hancheng, but I can't find time to meet. Now Hancheng is very busy and can't spare time to meet.
But I feel that for some things, just meeting once is enough. Once the decision is made, just wait for the date to get married.
"Okay, let's bake out the first batch of finished products first. The inside should be white and the outside should be dark green enamel cups. I will send a batch to the brigade commander then."
"Don't be in a hurry to give me anything. You haven't seen the girl I told you about last time? How long has it been? If they didn't think you could do it, they would have found someone to get married to. Don't you think so?"
The pressure from the master was quite tight. Han Cheng couldn't bear the warm reception, but you couldn't think of any good way to refuse. Although Han Cheng didn't know whether it was appropriate or not, he really couldn't spare the time.
Go and see it. Besides, what can you do if you see it?
"How can I get married if I don't have anything?"
"Oh, what are you talking about that won't make you rich? Just wait and wait until I find that girl and you two can meet."
