Chapter 281: Bringing warmth to the corn? (Second update)

Work is easier when there are more people. In just over a day, this horizontal deep hole boring machine was installed.

The test material is a metal cylinder more than two meters long, which has been processed and fixed on the fixture.

Then I started testing. While testing, Liu Hai kept stopping the machine to get tools to measure and inspect, and then debugged.

Liu Hai didn't know if there was such equipment at Benxi Iron and Steel Co., Ltd. Logically speaking, there should be.

However, I generally don’t ask other colleagues if they have bangs, only if I have them do I really have them.

After half a day of debugging, the equipment was almost ready, but unfortunately there was no five-meter-long material.

What Liu Hai doesn't know is that my country's first boring machine was actually produced in 56. Of course, that one can't be compared with this one. That one was the T68 model.

Of course, even if the processing accuracy and hole diameter of the same equipment are the same, there are differences.

Liu Hai believes that the boring machine he built should be relatively advanced in the country. The main reason is that when doing the self-tightening technology of the body tube later, the diameter of the inner hole needs to be constantly tested and adjusted.

Instead of the trouble of pulling a gun barrel back and forth, it is better to build a machine yourself and use it whenever you want.

In addition, subsequent large excavators also require hydraulic cylinders that are long enough.

The type of shield machine that will be built in the next two years will also require large hydraulic columns.

Putting this equipment here is definitely not simple. It is used to make gun barrels.

"Section Chief, do you want to conduct more experiments?" Li Dali asked.

"Tomorrow I'll go to the factory director and ask him to apply for two materials and we'll do it again. We don't have any ready-made materials here." This kind of material is not generally available, and the equipment department may not be able to make the decision, so The bangs didn't go there.

Moreover, this deep hole boring machine is made of cast iron, and the stress is removed by heating. It does not take as long as leaving it outside to naturally remove stress, so it needs to be recalibrated and maintained after two years of use.

This is impossible because the domestic steel industry itself started late and there is not so much idle steel to put there to remove stress.

Sun Aiguo has not been in his office for the past two days and has gone to other places. Even when he goes to work, he drives in from the maintenance department and goes around it.

"Factory director?" Liu Hai went to the factory office for a walk in the morning. He didn't see the factory director coming back until he saw the factory director coming out of the maintenance department.

"Forget it, all those acquaintances from the west, south and north of the city came to block the door. Aren't we going to need to replace equipment in the factory? These guys are well-informed. If they want to deny it, they will look up and look down. If they give it, there is nothing they can do. Give me so much." Sun Aiguo shook his head and said with a wry smile.

"Director, I have something to do with you. I want to apply for some materials for experiments." Of course Liu Hai knew that there must be a shortage of domestic processing equipment. A factory has seven or eight processing equipment, and it can produce any industrial product. of.

If it's not feasible, it would be a good idea to get two hydraulic presses to stamp lunch boxes.

"If you need any materials, just go to the Equipment Department." Sun Aiguo waved his hand and said.

"The material this time is a bit special. I would like to apply for two five-meter-long, unprocessed gun barrel rough blanks." Liu Hai saw the factory director about to leave and quickly stopped him.

When Sun Aiguo heard this, he asked doubtfully: "Wu Mi, I remember that our factory has materials for producing hydraulic cylinders?"

"The materials are different, the longest one is only two meters." Liu Hai said.

"Aren't I planning to produce assault guns? When upgrading the equipment this time, I made a horizontal deep-hole boring machine."

"We are also preparing for the production of larger excavators in the future. As the excavators get bigger, the hydraulic arms need to be thicker," Liu Hai explained.

When Sun Aiguo heard this, he knew that it was not simple. Don't listen to Comrade Liu Hai's casual words. His casual words were not simple.

"Let's go and have a look!" Sun Aiguo became interested at this moment and didn't care about other anxious things in the factory.

Arriving at the workshop of the Maintenance Department, Sun Aiguo was a little stunned when he looked at this big guy.

Although I expected that Liu Hai would have to process five meters of material.

But this big guy, nearly 16 meters long and three meters wide, is the largest bedroom boring machine Sun Aiguo has ever seen.

"Comrade Xiao Liu, is this something you made by the way?" Sun Aiguo looked at this big piece of equipment and asked while stroking it.

"I'm just planning ahead. I'll use it in many places later." Liu Hai said with a smile.

"I'm afraid this is a rare piece of equipment in the country. Except for some confidential military factories, it probably doesn't exist anywhere else, right?" Sun Aiguo walked from here to there, looked around carefully, and then said.

Then he saw what was being processed on the test car next to him. Does Sun Aiguo know how difficult the technology of a deep hole boring machine is?

There are too many problems involved, which is why when processing five-meter-long parts, the entire equipment is close to 16 meters. The reason is that it is long because it needs to be stable.

"I just thought that no matter what experiments we do in the future, it will be more convenient, and we will use it more in the future. If we apply for a machine from above and have the time, we can do it ourselves." Liu Hai heard this and explained.

When Sun Aiguo heard Liu Hai's words, he naturally nodded. If he wanted equipment from another factory, he would have to go to his superiors because he couldn't produce it himself.

"In addition, a crane is also needed. There is also a hydraulic column inside the crane's big arm."

"Okay, are two sticks enough? How about a few more?" Sun Aiguo heard this and asked again.

"Of course it's no problem, let's get a few more." Liu Hai thought to himself, anyway, he will have to do the barrel test in the future.

Sun Aiguo lowered his hat, wore factory work clothes, and came to the temporary office. He directly took the phone to report to his superiors.

When the leader heard Sun Aiguo's request, he immediately agreed and asked curiously.

After all, the five-meter-long barrel is not made of ordinary material, and it also has a relatively large diameter.

The leader hung up the phone and touched his chin. Of course he knew what it meant to be able to process a five-meter-long deep hole boring machine.
Moreover, the leaders believe that the products coming from the motorcycle factory are definitely not ordinary goods.

Nowadays, domestic shopping units all know that the quality of original products produced by motorcycle factories is much better than those produced by other subsidiary factories.

Because the motorcycle factory has always been taking into account the export business, any unqualified products will be re-smelted into materials and then reprocessed, and no unqualified products will be allowed to leave the factory.

This is not the case with other factories. Everything that can be used must be shipped out of the factory. This does not mean that standards are not strictly enforced, but that the demand is too great now.

The industrial environment at that time can be seen when the director of Haier Refrigerator smashed the refrigerator. This was still a later era, not the 70s and [-]s.

Therefore, products from motorcycle factories are more popular, but now almost all motorcycle factories are exported, and there are basically very few products from motorcycle factories available in China.

Excavators are also exported. A bunch of poor brothers from the Mainland in the world. Not to mention the excavators from the [-]s, even the steam excavators left over from the former colonies are all high-tech.

Therefore, excavators from the Mainland are very popular among the poor brothers. After all, the Mainland offers half-buy and half-free, so just charge the cost price.The mainland has a very good reputation internationally. Historically, after beating Third Brother, third world countries started to have opinions on us. But now there are few people in the third world who can speak for Third Brother.

After all, your third brother didn’t sell me an excavator or a tractor cheaply, and he didn’t even give me a motorcycle. Why should I talk to you?
In fact, it’s not that the third brother didn’t want to sell things, but that after this incident, many rich people ran away. It is said that all the rich people in the entire city ran away with their families, and even the poor ran away. , the city was even more chaotic, and many shops and factories were robbed.

It is said that even the military personnel in the city ran away at that time, running faster than the residents.

Many leaders of third world countries ride in ZTE brand luxury off-road vehicles.

Historically, there have not been so many flagship products from the Mainland that have been welcomed by third world countries.

The most depressing one is Big Brother. I originally thought that there would be no solution if the experts were withdrawn to the mainland for development. Who would have thought that others would be prosperous and the products they exported would be better than ours.

A week later, a six-meter-two truck drove into the motorcycle factory.

The samples I asked for were brought over. There were as many as 20 bangs, all of which had been roughly processed.

The truck drove directly to the maintenance department. The people in the maintenance department first further processed the roughly machined barrel, turned it, and ground it to sufficient accuracy, and then put it on the boring machine.

The deputy director of the motorcycle factory in charge of military products, Sun Aiguo and others watched as a five-meter-long, processed gun barrel was placed on top of the equipment.

Liu Hai led Li Dali and others to do some debugging and calibration before starting the machine.

Not only does it have a machine, but it also requires processing technology. The speed during processing is crucial. If the processing is too fast, it will not only waste equipment, but also cause some effects due to excessive temperature.

It doesn't matter if you process slower, but it will waste time, so you must have a suitable speed.

After the processing was completed, Liu Hai took Li Dali and others to test it.

"How is it?" Sun Aiguo asked anxiously when he saw Liu Hai and others completing the test.

"There is still a little problem." Liu Hai shook his head.

Of course, Liu Hai is not making a gun barrel, but testing equipment.

The manufacturing process of the gun barrel is very complicated. The manufacturing process of the smoothbore gun barrel: primary tube drilling-heat treatment-alignment-turning-flaw detection-deep boring-shaft furnace annealing-hydraulic self-tightening machine.

The bangs are just a test of the performance of the equipment. Of course, there is no final process in this era because that kind of machine has not yet been manufactured.

"What's the problem?" When Sun Aiguo heard this, he asked nervously, is this big guy useless?

"Our technology is not good enough. The processed inner wall is not smooth enough and there are some small flaws." Liu Hai shook his head and said.

To make the inner wall of the barrel look like a mirror, it requires the superb experience of skilled workers. The skills of Liu Hai and others are not very good, so the processed products have some minor flaws.

"Is there something wrong with the equipment?" Sun Aiguo breathed a sigh of relief when he heard this and asked quickly.

"There is nothing wrong with the equipment, and the hole diameters processed are all in compliance with the standards." Liu Hai took the data recorded in the notebook.

Sun Aiguo breathed a sigh of relief when he heard this, and the deputy director in charge of military industry in the factory also breathed a sigh of relief.

"Can this kind of equipment be productive?" Sun Aiguo asked again.

"Mass production is not a big problem, but the output of this kind of equipment is relatively low, and the requirements for workers are relatively high." Liu Hai said.

This kind of processing technology relies entirely on the workers to look at the shape of the cut to judge whether there is a problem with the tool feed.

If a novice does this, he or she will probably fail.

"We don't have much demand for this, so we can only train workers slowly." The deputy director of the military industry spoke at this time.

"As long as there is a need, we can produce it." Having said that, Liu Hai certainly had no objection.

"Well done, Xiao Liu. Our military industry has a lot of demand for this kind of equipment, especially this model." The deputy director in charge of military industry was not from the factory, but from the ministry.

As for which ministry it was in, of course it was in charge of military industry.

As for how long it would take to produce this equipment, and how much it would produce, there was no plan on the spot.

What equipment are you going to produce now?It doesn't mean placing an order on the spot, because materials and other things need to be planned.

Even if we talk about production now, we have to wait until the materials are in place.

That is to say, the motorcycle factory has a lot of material plans. It can first take out some of the materials to produce equipment, and then return the misappropriated materials when the planning materials from the follow-up department arrive.

If you change to other ordinary factories, they will give you as many plans as they want this year.

Because it is very troublesome to change the plan. If one or two factories simply change the plan, then the department has a flexible material plan.

If there are too many companies that change their plans, the work of superiors will be disrupted, because from upstream companies to downstream companies, they all made plans last year. How do you want to change them now?
Then Liu Hai discovered that the back of the boring machine no longer belonged to him, he just said that it was still on his own territory.

"Xiao Liu, they are just here to use this machine temporarily to see its performance." The deputy director of the military industry also greeted him in advance.

When these people came, they brought a lot of various materials for the gun barrel, and then started processing them in the workshop over there.

"Xiao Liu, is there anything better than high-pressure sodium lamps?" Sun Aiguo came to the maintenance department and asked while watching Liu Hai drawing.

"Director, why are you asking this? We don't produce it?" Liu Hai asked curiously. High-pressure sodium lamps have long been produced by other factories.

"My superiors asked me to ask, Big Brother has imported many high-pressure sodium lamps from us over the years, but they all complain that they consume more electricity." Sun Aiguo explained.

When Liu Hai heard this, he asked in confusion: "Big Brother has been importing these years, but they don't produce it themselves?"

"I'm not sure about this. Anyway, there are a lot of imports every year. The factory that made high-pressure sodium lamps used to have only 200 people. Now it is said that there are 800 people. The workload is still very large."

"Big brother, how many plant factories have you built?" Liu Hai felt something was wrong when he heard this.

"It is said that there are dozens of crops grown, and there are even tropical fruit trees. It is said that they use greenhouses to raise pigs and cattle with good results."

"And Big Brother is said to be able to provide a lot of fresh vegetables and fruits every winter. The leaders of Big Brother have a very good reputation in their country." Sun Aiguo's words surprised Liu Hai. Isn't the corn about to turn yellow?

But then I thought about LED lights. These lights are expensive to make in the mainland, but Big Brother can definitely do it.

"I have an idea here." Liu Hai touched his chin and said. In fact, the relationship between Corn and us is good now. It would be worse if we change to the next one. It's okay to help Corn.
