Chapter 67 The right time to develop a product
When the car passed by Kangka, He Tao also proposed to go to the construction site of the new city. As he wished, Guan Fei drove onto the crossroad between the two mountains to the new city.
The tourist bus behind also followed and did not go directly to the military sub-district along the main road.
When he arrived at the construction site of the new city, He Tao looked straight at it. Tens of thousands of people started construction at the same time on the same construction site. Such a huge construction scale has rarely been seen in China in the past two years. The speed of the construction of the new city also amazed him.
From the report, he knew that the first project in the university town was not completed except for the main project of the teaching building of the University of Science and Technology, and the student dormitory, laboratory building, gymnasium, etc. had been completed.
But the words are always dry. When he saw a large campus covering thousands of acres on his own, the transplanted grasslands, flower beds, artificial lakes, rockery, pavilions, tennis courts, circular sports fields, as well as the standing student dormitories, libraries, and large indoor gymnasiums that can accommodate thousands of people, still exuded a shocking expression.
When he looked up at the teaching building that had been built to the eleventh floor and had another floor to be topped off, his expression was particularly serious.
It can be said that this is a school that will be opened soon.
The scale of two thousand acres is limited by the urban terrain, which is much smaller than many universities in China that often cost tens of thousands of acres. However, many universities in China are comprehensive universities, and one university includes two comprehensive disciplines in liberal arts and science, and there are many departments below.
Guan Fei designed the planning drawings, each university targets a clear specific discipline. It does not count as the School of Economics and Management or the School of Medicine, all universities are pure science and engineering!
After leaving the school, they went to see the construction of residential areas and commercial areas.
He was even more moved when he looked at the small high-rise buildings with twelve floors in the entire community, and each building had more than two elevators.
This is a high-end residential area. Even provincial and municipal cadres in China still live in government courtyards. The room area may be larger and the living environment is better, but no one can live in an elevator apartment!
When he heard that this was only the first batch of ordinary apartment buildings, and a high-end villa group would be built on the banks of the river in the future, he was speechless.
If such conditions are really completed, it will be no worse than those of developed countries abroad.
When they passed by a sewer pipe construction site under construction, He Taoxing also went in and watched it.
He found that this was not a sewer, but an underground tunnel.
The sewer, which is three meters wide and two meters high, is buried deep underground, and the top of the tunnel is fifteen meters away from the ground. In the entire tunnel, various pipes of different thicknesses are fixed in an orderly manner. There are sewage pipes up to half a meter thick, and there are also tap water pipes of twenty or thirty centimeters. There are wire pipes on the left wall and telephone lines on the right wall. Every ten meters, a support column will be set up in the center of the tunnel.
All lines are concentrated in this passage, which is convenient for staff to patrol and inspect at any time. If there is any problem, repair and replace it is also very convenient.
They walked and stopped, got out of the car from time to time to take a closer look, and did not arrive at the location of the military sub-district until the afternoon.
This time, He Tao did not have the chance to express his feelings for Guan Fei and the others' simplicity.
The Military Sub-district, Brigade Department, and each company have moved into new barracks. In the valley about one square kilometer, it is divided into a regular chessboard pattern by brand new buildings. Dozens of three-story military barracks are stacked, and each barracks have their own separate courtyard for gathering troops and teaching.
The barracks are not only a place for soldiers to rest, but also a place for learning and entertainment.
In each barracks, a large conference room and a small conference room were set up. There was also an activity room of about 200 square meters, which was marked with a badminton court and an indoor sports field for volleyball and basketball. There was also an open space next to it, and a table tennis table made by the military district wood factory was placed.
In the large conference room, he also saw a rolled-up large curtain and projector - it can also serve as a small cinema!
Such comfortable conditions have nothing to do with simplicity. It is simply great. Compared with the best military barracks in China, it is not bad at all, and it is still a bit better!
The soldiers I saw along the way were all full of energy, and from time to time I heard bursts of laughter from the soldiers.
From this laughter, it can be seen that the soldiers are very satisfied with the current conditions. Good living and living conditions in turn promote the soldiers' sense of belonging to this combat collective. The various development momentum of the military division has made these soldiers full of confidence in the future development of the military division and are willing to obey the arrangements of superiors. Retirement skills training, distribution and other preferential policies for military division soldiers further tie the soldiers their future together with the military division, and both fighting courage and will and determination have been greatly enhanced.
If the last time people came to the capital and saw the possibility of the future development of the military sub-district, then He Tao now, through his observation, this may have been transformed into a real thing.
It's enough to know this.
This time, they, especially the two old professors Zhao Wenliang and Fan Zhe, wanted to know the most about the current technical strength of the Military Sub-district.
Originally, they thought that they would not see much before the factories were officially opened. Who knew that they had made new discoveries before they arrived at the technical school.
At that time, the car was about to pass through a small valley when he heard a huge knock sound coming from inside, constantly.
"Where is this place? Why does it seem so noisy?"
Seeing that the tour bus stopped behind him, Guan Fei got off the back jeep and was pulled by Mr. Fan asked.
It happened that a Jiefang truck drove in. Through the open rear panel of the car, you could see several steel workpieces placed on it. Some parts of the surface of the workpiece looked a little black, as if they had been burned by fire.
"Is this just heat-treated?" Fan Zhe's eyes were very poisonous, and he could tell at a glance that this was a workpiece that had just been heat-treated.
"Yes! This is where we perform stress removal. After roughly processed workpieces are sent to heat treatment, they will be placed here, and then beat them for a long time through a vibration stress hammer to eliminate the internal stress of the workpiece." There is nothing to hide, Guan Fei said openly.
"Use a vibrating hammer to eliminate internal stress!" Fan Zhe's eyes lit up suddenly.
Stress is the internal deformation caused by the object after being hit or burned, due to the inability to move.
It is like when a person is hit, it may shrink into a ball. Various materials such as steel and wood will also change internally after being impacted by external shocks. The stronger the blow, the greater the change. These deformations will gradually stop after a long time, which is called stress elimination.
In ancient times, people knew that the wood that had just been cut could not be used directly because the firewood shrinks and drys out, it will be distorted and deformed. Therefore, the ancients had to leave the wood that had been cut for a year or two, so that the moisture inside it had been completely eliminated and the deformation was over before it was processed and made into shipboards, furniture, etc.
The same is true for steel.
When the accuracy requirements in the early stages are not high, generally there are only lathe production and other links, and the steel needs to be stress-removed. When the stress-removed equipment is not made, some spare parts of the equipment may be deformed, causing the machine to work efficiency, increase wear and consumption, seriously reduce the machine's service life, and even completely scrapped.
In order to eliminate stress, the traditional practice is timely and accurate, that is, just like dealing with wood, it is placed on the open space, exposed to sun and rain, and let it stand for a long time to release its internal stress.
This method is effective, but it takes too much time.
For example, if a machine tool factory wants to make a machine tool, it must smel the required steel and alloy castings several years ago, and then stand to remove stress. After the stress is eliminated, in the initial processing step, due to the violent collision of the tool on the material, new stress will be generated, so it will be put into place again.
Each time you sit, the shortest ones take several months and the longest ones take several years.
Therefore, if the machine tool factory receives an order and does not purchase its finished product, but wants to redesign the production and do not have the appropriate parts that have been removed from stress, it may take five or six years from receiving the order to final production completion, which can be said to be quite long!
In case of emergencies, such long stress treatment cannot meet the needs of the market at all.
The development of human science and technology is progressing with demand.
People need to quickly eliminate internal stresses of solid materials to meet flexible production needs, so they began to study this aspect.
This research began in the 1960s. Due to the slow progress and limited research methods, the waiting time to verify the results was too long. After more than ten years, we found a relatively reliable method to quickly eliminate stress, that is, the vibration method.
Isn’t stress generated by impact? Then, we apply a certain force to impact it at the corresponding position to help it release stress quickly. This is the research idea of the vibration method.
There is research on this aspect abroad, so the country naturally follows up quickly.
However, due to the impact of the unrest, limited investment and low automation level, domestic research progress is very slow. Foreign countries have basically summarized the laws of vibration method and started to be promoted in some industries, while domestically, they are still hovering at a low level and cannot be practical.
The main ones used in China are time-saving and heat treatment methods. The time-saving and heat treatment method takes a long time, and it goes without saying that the heat treatment method is to put the workpiece into the kiln and burn it at an appropriate temperature. It is also a method of using poison to fight poison.
However, the heat treatment method is difficult to eliminate stress in certain special locations. Moreover, after heat treatment, the workpiece is deformed greatly and processing is still required. This processing may generate new stress, so it is a helpless choice with a large investment, high energy consumption, and unsatisfactory effect.
Fan Zhe is a senior engineer at the Mechanical Design Institute and is naturally familiar with the vibration method. When he heard Guan Fei say that he was using the vibration method to eliminate stress, his eyes immediately lit up.
"Can you go in and take a look?" He asked excitedly.
"Of course!" Guan Fei smiled and led the way. Fan Zhe followed behind impatiently. Zhao Wenliang and others knew nothing about what vibration method they were, but they just followed him to watch the fun.
Zhao Zhonghua was responsible for civil affairs. After the construction of the new city was completed, he played the same role as mayor, so he came to the technical school more often. He knew about the workpieces after heat treatment in this valley, and he had also seen it. He had also seen the noisy thing, and he also heard others briefly explain what it was for.
It was because of his habit and in order to avoid the noisy voice, he rarely came here again since then.
But at this moment, he saw Fan Zhe's expression as if he was a pervert and saw a beautiful woman, and he wondered in his heart: Could that noisy thing be a good thing?
He Tao didn't understand this either, but he could observe his expression and look at Fan Zhe's excited expression, and he knew that Guan Fei had something good in his hand.
"That..., what is stress elimination?" He was very good at learning, followed Professor Van Zhe and asked without shame.
After Fan Zhe danced and passionately explained, he understood.
Not only did he understand, but everyone else understood. He Tao's face was flushed, and he felt the blood on his body was surging upwards.
Relieve stress!
This technology is too important, too critical!
If this technology is available, then the country can completely manufacture high-precision lathes, equipment, tank engines, fighter jets, warships as needed...
"This vibration...vibration stress elimination method is your own technique?" He immediately let Fan Zhe go, grabbed Guan Fei and asked.
“…it’s intelligence…”
"Go to your intelligence dealer!" Before Guan Fei finished speaking, he was blocked back in anger by He Tao. "I don't care if you bought it with an intelligence dealer. Do you have this technology? Are there any? How long does it take to eliminate the internal stress of a component?"
OK, next time I said I'll pick it up on the road!
Guan Fei regretted that a good excuse disappeared, shook his head and explained to him: "Your question is unscientific! The time required to eliminate internal stress of a component is related to its size, structure, and processing method. It takes a long time to eliminate stress in large equipment parts. At the same time, the processing methods are different, and the size of internal stress in the material is also different. If you ask this, I can't answer. I can only roughly tell you that it takes several days to eliminate stress on a lathe bed..."
"I want this technique!" He Tao stopped the railway without waiting for him to finish speaking.
Just kidding, this time is nothing compared to the time when it comes to emulation for several years.
Don’t be fools if you have such good skills!
"I can sell it to domestically made sub-vibrators, which cost only 6,000 yuan each! I will give you as much as you want!"
Guan Fei was not vague and immediately intervened.
Nonsense, even if Fan Zhe didn't find this thing, he would take the initiative to show them. The circuit structure of this sub-vibrator is very simple, and the processing of the vibration hammer is not very difficult. The price of 6,000 yuan is only 2,000 yuan!
This thing costs tens of thousands of dollars in foreign countries. The key to its value lies in the setting of vibration frequency waves, which is high technology!
In order to find suitable vibration frequency waves, foreign countries took more than 20 years to improve and correct them. It was not until the 1980s that they were finally finalized and promoted on a large scale. By the 1990s, except for a few high-precision manufacturing requirements, basically all factories used sub-vibrators to eliminate internal stress of the workpiece.
It was not until the 1990s that the country began to learn this technology gradually. But at that time, better stress removal technology was already available, and this thing seemed useless. It was sold online and there were very few buyers.
But in this era, that is truly a big killer!
