"How come I don't know?" Qin Zhongnian said in surprise.

This question is really a bit difficult to answer, it is true that you are the chief engineer, but you have just arrived at Linyi for a few days, how can you know about Linyiji? But Han Weichang can't scold Qin Zhongnian like this, there is no other reason, people are leaders, can you say that leaders are ignorant?

Fortunately, Qin Zhongnian also reacted quickly, and said with a self-deprecating smile: "I'm confused, the matter of Linyi must be better known to Lao Han." Lao Han, let's talk about it, when did we have a forging machine tool. ”

Han Weichang said modestly: "Where is it, Chief Engineer Qin has been in the Mechanical Design Institute for so many years, and he must know the situation in the industry very well. However, the matter of Linyi Machine's forging machine tool was also vigorous back then, and then it was a little bit out of business, so Chief Engineer Qin didn't know, and it was normal. ”

Qin Zhongnian pointed to the sofa with his finger and said, "Old Han, sit down and tell me about this matter." ...... By the way, Don Jr., you can sit down and listen to what's going on. ”

Han Weichang sat down and began to introduce the past to the two. It turned out that this was still a matter of the early 60s, when the country engaged in economic adjustment, many subordinate enterprises were changed from central jurisdiction to local jurisdiction, and Linyi Machine was also delegated to Dongye Province and became an enterprise under the Dongye Provincial Machinery Department. At that time, the Jiangnan Shipyard built China's first 10,000-ton hydraulic press, which caused a sensation throughout the country, and the leaders of Dongye Province instructed the mechanical system of Dongye Province to also build hydraulic presses in order to rub the hot spot. As the strongest machinery enterprise in Dongye Province, Linyi Machine undertook this glorious and absurd task.

"What happened later?" Tang Zifeng asked with interest.

"I've heard from the old engineers, too. At that time, the technical department worked day and night for more than three months, broke through many technical difficulties, and finally designed a 2,000-ton hydraulic press. As for the 8,000-ton hydraulic press required by the provincial leaders, we can't get it anyway. Han Weichang said.

Qin Zhongnian said: "It's not bad to be able to make 2,000 tons." The greater the pressure of the hydraulic press, the higher the requirements for materials and structures, and ordinary materials simply cannot withstand such great pressure. The Jiangnan factory was built by concentrating the strength of the whole country, and it was really powerless to rely on the strength of its own factory to do it. ”

"The baler that Jin Yao wants over there is also a forging machine, what is its pressure requirement?" Tang Zifeng asked.

Qin Zhongnian said: "I just saw that the pressure they asked for was 100 tons. ”

"We've even done 2,000 tons, isn't it easy to do 100 tons?" Tang Zifeng blurted out.

Qin Zhongnian was stunned for a moment and said: "In terms of pressure alone, the device with a pressure of 100 tons is not very difficult, even if we haven't done it in the past, it is not difficult to start from scratch, the technology is ready-made." The key is that we are engaged in cutting machine tools, and it is a bit unprofessional to engage in forging equipment. ”

Tang Zifeng looked at Qin Zhongnian and asked, "Chief Engineer Qin, I didn't understand. Are you saying we can't build this kind of equipment, or are you saying we shouldn't be able to build this kind of equipment?"

"The main thing is that it shouldn't be made. Qin Zhongnian said, "As for the manufacturing capacity, we haven't built a baler in the past, but I looked at the requirements, the structure of this thing is not complicated, with the manufacturing capacity of our factory, it is absolutely no problem to build a few units." ”

"I'm down!" Tang Zifeng almost burst into foul language. This lack of understanding technology is really his own shortcoming, and he almost let Lao Qin be blinded. I still think why the forging equipment has a high technical threshold, and I can't reach it on tiptoe. It's absolutely no problem to co-author a few units, but Lao Qin is not willing to do it.

"Chief Engineer Qin, when has this been. Our factory is almost so poor that you are going to ask for food, and you are still picky. These 4 machine tools, my junior sister can say, the gold waste is planned to be introduced from abroad at a price of 50,000 US dollars, we suffer a little loss, according to 400,000 yuan a set of next, it is also an output value of 1.6 million, you talk about it, is there a gross profit of 400,000 yuan?" Tang Zifeng asked Qin Zhongnian, Jin Yao Waste Materials Recycling Company, which was directly referred to as gold waste by him, and I don't know if Mao Yaguang will be mad when he hears it.

"The gross profit of 400,000 yuan, that is, 100,000 yuan per unit, and the remaining 300,000 manufacturing costs, I think it is more than enough. Qin Zhongnian said. This guy is the master of the mechanical design institute, all kinds of machinery have been done, and the forging machine tool is no stranger to him. Just now, he has figured out the principle and structure of the metal baler, roughly calculated, the manufacturing cost of 300,000 units is completely fine, if it can really be sold for 400,000 units, 100,000 gross profit is completely guaranteed.

"4 pieces of equipment, 400,000 gross profits, don't you want it?" asked Tang Zifeng.

Qin Zhongnian was a little embarrassed. He is also preconceived, always feel that Linyi machine is to do cutting machine tools, should not be to do forging machine tools, which is also a habit developed in the work of ministries. Now that Tang Zifeng said it, he remembered that his current role was the chief engineer of Linyi Machine. In these few factory meetings, Zhou Heng spent most of his time talking about business issues. A business with an output value of 1.6 million yuan is definitely not dispensable for today's Linyi machine. If you can take it, why not do it?

"I'm an old brain!" Qin Zhongnian was a frank person, he knew that he was wrong, so he immediately admitted it, and he said: "Xiao Tang, I was wrong. In fact, the technology of metal baler is relatively mature, our country has developed it in the 70s, and the main technology is engaged in our mechanical design institute. The technology of the baler has improved over the years, but the basic principle remains the same.

"To be honest, the manufacturing difficulty of the baler is much lower than the lathes and milling machines we make every day. It requires more than two levels of machining accuracy for parts and components than machine tools, and if we are willing to build a baler, it is definitely much better than that of several professional factories in China. ”

Han Weichang also nodded again and again, and said: "That's right, our Linyi machine is to build precision machine tools, and the processing accuracy requirements of each component are very high." Isn't this metal baler just to make a box out of iron sheets, stuff those scrap iron into it, and then use a hydraulic rod to pestle it inside, and pestle the scrap iron into a lump, how high can the accuracy be required?"

"Han Gong, what you said is too rough, isn't it? Although the baler is not a difficult product, it is not as simple as you say. ”

Qin Zhongnian was speechless. When the domestic independent development of metal balers, he had just come to work in the mechanical design institute and helped the technical masters, so he still had a good understanding of this situation. Han Weichang said that the principle was right, but after he described it, it seemed to be like beating adobe in the countryside, which was really insulting.

In fact, this kind of equipment also has its technical difficulties, such as...... , or ......

Uh, it's still not like that, Qin Zhongnian thought about it for a while, but he didn't come up with any technical difficulties worth bragging about. At the time of development, it was mainly subject to defects in materials and processes, and we spent a lot of energy to solve these problems. After so many years, the level of domestic materials and craftsmanship is no longer the same as in the past, and now it is ridiculous and generous to talk about the technical difficulty.

In fact, the structure of a lid-closing double-head pressurized metal baler is very simple. The whole machine is divided into two parts, namely the main engine and the power system. The main engine includes a body, that is, the "iron box" mentioned by Han Weichang, of course, it is actually made of very thick cast iron, because it has to withstand a lot of pressure; two hydraulic presses perpendicular to each other are used to tighten the scrap iron "pestle", in addition to the cover, locking mechanism, etc.

The power system is the system that operates two hydraulic presses, including oil tank, oil pump, motor, control valve, pipeline system, electrical system and so on.

Linyi machine has not done metal baler, but the cutting machine tool also needs to use cast iron to make the body, use hydraulic devices to control the take-off and landing of the worktable, and also have a large number of control systems. It can be said that the technology involved in the manufacture of metal balers has been mastered by Linyi machine, and only drawings need to be drawn to be able to manufacture the equipment.

This is the ability of a large machinery manufacturing enterprise, as long as there are drawings, almost anything can be made. In the era when Western countries imposed a total embargo on China, China often took a foreign piece of equipment and dismantled eight pieces, drew the parts one by one, and then was able to copy the same equipment itself. Of course, due to the limitations of materials, processes, processing equipment, etc., China's imitation equipment often has its form but not its spirit, and its feasibility, accuracy and other aspects are slightly inferior to imported equipment.

When it comes to the four metal balers required for the "golden waste", there are basically no of the above concerns. Because the metal baler is really not a precision equipment, it is used to extrude some loose scrap metal into "lumps", and it is a stupid black and coarse job.

"Don Jr., you can go and tell the other party that we are fully capable of providing them with this batch of metal balers. You go to arrange a salesman, and it is best to bring another engineer to Jinyao to go to Jinyao and discuss with them in detail the specific product requirements and the corresponding price. After getting the other party's requirements, I was sure that I could complete the design within half a month, and half a month for the manufacturing process was enough. That is, we can deliver to them within a month. Qin Zhongnian said with confidence.

Tang Zifeng said: "That's great, so let's do it, don't arrange any salesman, since it's the business that my junior sister contacted, I'll go on a trip myself." As for the engineers, it's not ...... Hey, old Han, what are you running!"
