When will I have a long tassel?

"Lin Yiji has made a forging machine tool? Why didn't I know?" Qin Zhongnian said in surprise.

This question is really difficult to answer. It is true that you are the chief engineer, but you have just arrived at Linyi Machinery a few days ago. How can you possibly know everything about Linyiji Machinery? But Han Weichang couldn't attack Qin Zhongnian like this, for no other reason than he was a leader. Can you say that a leader is ignorant?

Fortunately, Qin Zhongnian also reacted quickly and said with a self-deprecating smile: "I'm confused. Old Han must know better about Lin Yiji. Old Han, tell me, when did we do something about Lin Yiji?" Forging machine tool."

Han Weichang said modestly: "Where is it? Chief Engineer Qin has been in the Mechanical Design Institute for so many years, so he must have a very good understanding of the situation in the industry. However, Lin Yiji's development of forging machine tools was also a big deal at the time, but later it became a bit unresolved. That’s all, so it’s normal that Chief Engineer Qin doesn’t know.”

Qin Zhongnian pointed to the sofa with his finger and said: "Old Han, sit down and introduce this matter to me. ...By the way, Xiao Tang, please sit down too and listen to what's going on."

Han Weichang sat down and began to introduce this past event to the two of them. It turns out that this happened in the early 1960s. At that time, the country was undergoing economic adjustment, and many ministry-affiliated enterprises were changed from central jurisdiction to local jurisdiction. Linyi Machinery was also decentralized to Dongye Province and became an enterprise under the Dongye Provincial Machinery Department. At that time, Jiangnan Shipyard built China's first 10,000-ton hydraulic press, which caused a sensation across the country. In order to gain popularity, the leaders of Dongye Province instructed Dongye Province's mechanical system to also build a hydraulic press. They said that if they could not build a 10,000-ton hydraulic press, they would build seven or eight. Thousand tons is also fine. Linyi Machinery, as the strongest machinery company in Dongye Province, has undertaken this glorious and absurd task.

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

"I also heard it from old engineers. The technical department at that time worked day and night for more than three months, overcoming 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 It can't be done no matter what," Han Weichang said.

Qin Zhongnian said: "It's not bad to be able to produce 2,000 tons. The greater the pressure of the hydraulic press, the higher the requirements for materials and structures. Ordinary materials simply cannot withstand such heavy pressure. The Jiangnan factory has concentrated the strength of the whole country. Linyiji wanted to do it with the strength of its own factory, but it was really beyond its capabilities."

"The baler Jin Yao wants is also a forging machine. What is its pressure requirement?" Tang Zifeng asked.

Qin Zhongnian said: "I just saw it. The pressure they require is 100 tons."

"We have even done 2,000-ton projects. Isn't this 100-ton project easy?" Tang Zifeng blurted out.

Qin Zhongnian was stunned for a moment and said: "In terms of pressure alone, a 100-ton pressure device is not that difficult. Even if we have never done it before, it is not difficult to start from scratch. The technology is all ready. The key is that we are doing it. For those who work on cutting machine tools, it would be a bit unprofessional to change their profession to engage in forging equipment.”

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

"The main reason is that it shouldn't be built." Qin Zhongnian said, "As for manufacturing capabilities, we have never built balers in the past, but I looked at the requirements and found that the structure of this thing is not complicated. With our factory's manufacturing capabilities, we can It’s absolutely no problem for a few to come out.”

"I'll do it!" Tang Zifeng almost cursed. This lack of understanding of technology was really my shortcoming, and it almost fooled Lao Qin. I thought the forging equipment had such a high technical threshold that I couldn't even reach it on tiptoe. There is absolutely no problem in building a few co-authors, but Lao Qin is not willing to do it.

"Chief Engineer Qin, when did this happen? Our factory is almost so poor that we have to beg for food, and you are still picky and picky. My junior sister can tell you that these four machine tools are planned to be sold for 50,000 US dollars each. The price is imported from abroad, so we suffer a little loss. According to 400,000 yuan per unit, the output value is also 1.6 million. Tell me, is there a gross profit of 400,000 yuan?" Tang Zifeng asked Qin Zhongnian, Jin Yao scrapped The material recycling company was simply referred to as Golden Scrap by him, and he didn't know if Mao Yaguang would be mad when he heard it.

"The gross profit of 400,000 yuan, which is 100,000 yuan per unit, and the remaining 300,000 yuan manufacturing cost, I think is more than enough." Qin Zhongnian said. This man is the head of the Mechanical Design Institute. He has experience in all kinds of machinery, and forging machine tools are no stranger to him.

In just a short while, he had already figured out the principle and structure of the metal baling machine. After a rough calculation, the manufacturing cost of 300,000 units was absolutely no problem. If 400,000 units could be sold, 10 A profit of RMB 10,000 is completely guaranteed.

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

Qin Zhongnian was a little embarrassed. He also had preconceptions. He always felt that Linyi Machinery was a cutting machine tool, so it should not be a forging machine tool. This was also a habit he developed while working in ministries and commissions. Now that Tang Zifeng mentioned it, he remembered that his current role was the chief engineer of Linyiji. During the past few factory affairs meetings held in the factory, Zhou Heng spent most of the time discussing business issues. A business with an output value of 1.6 million is definitely not dispensable for today's Linyi machine. Since you can get it, why not do it?

"I'm an old man!" Qin Zhongnian was an open-minded person. He knew he was wrong and immediately admitted it. He said, "Xiao Tang, I was wrong. In fact, the technology of metal balers is relatively mature. Our country had already developed it in the 1970s, and the main technology was developed by our Machinery Design Institute. The technology of balers has improved over the years, but the basic principles remain unchanged.

"To be honest, the difficulty of manufacturing a baler is much lower than that of the lathes and milling machines we build every day. Its requirements for processing precision of parts are more than two levels lower than that of machine tools. If we are willing to build a baler , definitely much better than those made by several domestic professional factories.”

Han Weichang also nodded repeatedly and said: "Yes, our Linyi Machinery makes precision machine tools, and the processing accuracy of each component is very high. This metal baler just makes a box out of iron sheets, and packs those The scrap iron is stuffed in, and then a hydraulic rod is used to punch it in, and the scrap iron is punched into lumps. How high the accuracy can 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 said."

Qin Zhongnian was speechless. When the country was independently developing metal balers, he had just started working at the Mechanical Design Institute and helped the technical experts, so he was quite familiar with the situation. The principle that Han Weichang said is correct, but when he described it, it looked like someone making adobe in the countryside, which was really degrading to politeness.

In fact, this kind of equipment also has its own technical difficulties, for example..., and for example...

Well, it's better not to mention it. Qin Zhongnian thought about it for a while, but he couldn't think of any technical difficulty worth bragging about. When it was developed, it was mainly limited by defects in materials, workmanship, etc., and everyone spent a lot of effort to solve these problems. After so many years, the level of domestic materials and craftsmanship is no longer the same as in the past. It is completely ridiculous to talk about the technical difficulty now.

In fact, the structure of a closed-cover 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 machine includes a machine body, which is what Han Weichang calls an "iron box". 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 remove waste. The iron "pestle" is tight, and there are also machine covers, locking mechanisms, etc.

The power system is the system that controls two hydraulic machines, including oil tanks, oil pumps, motors, control valves, piping systems, electrical systems, etc.

Linyi Machinery has never made a metal baling machine, but the cutting machine tool also needs to be made of cast iron to make the body, use hydraulic devices to control the lifting and landing of the workbench, and also have a large number of control systems. It can be said that Linyiji has mastered all the technologies involved in manufacturing metal balers. It only needs to draw drawings to manufacture the equipment.

This is the ability of a large machinery manufacturing company. As long as it has drawings, it can build almost anything. In the era when Western countries imposed a comprehensive embargo on China, China often took a foreign equipment and dissected it into pieces, drew the parts one by one, and then was able to imitate the same equipment itself. Of course, due to limitations in materials, technology, processing equipment, etc., the equipment imitated by China often has its own shape but not its spirit, and is slightly inferior to imported equipment in terms of feasibility and accuracy.

Specific to the four metal balers required for "gold scrap", the above concerns basically do not exist. Because the metal baling machine is not really a precision equipment. It is used to squeeze some loose scrap metal into "lumps". It does a stupid and rough job. Linyi machine can make precision With the level of craftsmanship of the grinder, it is really easy to build a few metal balers.

"Xiao Tang, you can tell the other party that we are fully capable of providing them with these metal balers. You can arrange for a salesperson, preferably an engineer, to go to Jinyao and discuss it with them in detail. Let’s talk about the specific product requirements and corresponding prices. After getting the requirements from the other party, I am confident that the design can be completed within half a month, and the manufacturing process can take half a month. In other words, we can complete the product within a month. We can deliver to them." Qin Zhongnian said with confidence.

Tang Zifeng said: "That's great, let's do this. Don't arrange any salesmen. Since it is the business that my junior sister contacted, I will go there myself. As for the engineer, isn't this... Hey, Old Han, Why are you running!"
