Chapter 443: Technological innovation

"The gasoline engine we use now is the production line of Magic Capital. This thing is still the technology of the Soviet Union in the 1950s. It is too old."
"Not to mention the 1950s. If we look at American standards, this is their technology in the 1930s, which is completely World War II. We have good materials now, so we can make a new one."
"You young people also want to follow President Zhou to make new standards blindly? President Zhou doesn't understand, you don't understand? Although the technology of this gasoline engine is old, it is durable and durable."
"Old comrade, you can't just look at the skin and durable, but also take care of the economy. Our gasoline and materials are not bad now, and the engine compression ratio can be reached ten, which is much stronger than the current‘ five ’.

"Yeah, yeah. Although our materials are not as good as foreign ones, they are much stronger than a few decades ago. The engine cylinder wall can be made thinner and the machining accuracy can be fully satisfied."
"You are all wrong. This single-cylinder gasoline engine has little potential to tap. I feel like copying Japanese technology. Why bother?"
A square table is surrounded by three generations of old and young technical staff, and seven or eight people are surrounded by several drawings to discuss it.
The sandmaker Lao Zhang wore a faded tooling, frowned, listened to the discussion, and left with a sigh. He walked out of the iron gate of the workshop, exhaled a long breath, and felt the long-lost ease.
Lao Zhang has severe lung disease due to his long-term work in the mold turning sand line in harsh environments. He coughs every day, and he can kill him every time.
When I arrived in Tianyang, I went straight to the hospital to take x-rays. The doctors shook their heads and said that they had no tricks and could only treat conservatively. As a result, the logistics of "Holy Light" sent him a bottle of "boiling water" and let him drink it.
On the day he drank, Zhang coughed desperately in the toilet. Unlike previous painful coughs, he relaxed one point each time he coughed this time and coughed up a lot of thick sputum and blood.
He drank 'boiling water' for three consecutive days, during which Mr. Zhou also personally visited him once. The two sides shook hands and talked a few words, and Zhang felt as if he had retrieved a life.
Sleeping weekday and night, Lao Zhang coughed most of the time. The whole family followed with insufficient sleep. Sleeping in Tianyang for three days, he was so happy.
Lao Zhang asked himself what medicine he was drinking?
The "Holy Light" only answered one sentence, "It is probably that Tianyang is more supportive of soil and water, and it is easy to heal any disease."
He was almost sick, and Zhang had to work. The workshop he is staying in is an old factory building built in the 1960s by Tianyang Machinery Factory. The beam structure is more than 5,000 square meters, which is quite spacious.
"Shengguang Machinery" wants to engage in "Snake Swallow Elephant". However, Tianyang Machinery Factory is too large. Currently, it has only rented a few of its workshops for production.
When rented, the workshop was messy and dirty. Zhou Qingfeng immediately requested the transformation of the entire workshop. The ISO standard has a clear stipulation on the cleanliness of the workshop.
Technical things are not easy to get done, and cleaning has to be done.
Can't learn how to make a plane in Asan. Workers wear slippers into the workshop. What's more, they can't learn how to build a tank. The workers directly in the tank body.
As for Asan's ability to launch the aircraft three times and not yet build an aircraft carrier, Zhou Qingfeng was not worried. This is an absolute nationality, and you ca n’t learn it if you do n’t drink enough of the Ganges water.
In the old workshop, there were originally dozens of old and grandfather equipment, like an industrial museum.
For example, the large-scale thermal insulation sand box used for sand turning is a Soviet product at a glance. The volume is huge and the energy consumption is also high. As soon as this thing started, the light bulbs in the entire workshop had to flash twice.
The quality of the insulation flask is related to the quality of the casting. In particular, the slower the cooling process of large castings, the better. It needs to be kept in the sand box for a long time, and the temperature should be reduced to two Baidu before opening the box.
However, the holding time is long, the equipment turnover is slow, and the efficiency is low. Small local factories will open the box at fifty or six hundred Baidu to expose high-temperature castings directly to cold air.
The castings produced by this process look okay, but they are equivalent to overall quenching, the internal stress is extremely large, and it is difficult to make good product quality.
Many domestic machine tool factories do just that, the production in the map saves costs and costs, does not pay attention to details, the quality is not as good as Japan and Germany, and even Taiwan goods are not as good.
After the workshop was rented, the old Soviet antiques were removed, and the overall space was cleaned up and transformed.
Zhou Qingfeng re-ordered the goods in Modu. For example, the sandbox has no technical content, it is a very large ‘heats fast’, and the domestic ones are quite easy to use.
Slowly increase the temperature to reduce the pressure on the power grid. Slowly reduce the temperature to ensure the quality of the castings. At the same time, heat insulation is performed to reduce energy consumption. The equipment does just that.
Many details in production need to be controlled by experienced workers like Lao Zhang. As soon as he came, the scrap rate of the cylinder castings of the 50cc small engine was reduced by half, which greatly improved the production speed and quality.
This cost naturally drops.
When the old Zhang Jue felt that he could afford the salary and treatment given by Zhou, a new trouble came.
"Holy Light" is undergoing technological upgrades, and the factory introduces computer-aided design and manufacturing. It is not only the machining that needs to be turned to CNC machine tools, but even the foundry must also have a low margin to reduce machining time.
Although the transformation of a small 50cc engine with cad is really a big deal, Zhou Qingfeng's meaning is very simple-will I never only produce this kind of small displacement engine?
The technical reserves should still be on.
CAD technology is actually the coordination of many disciplines and processes such as mold, casting, machining, numerical control, and computer design. This is not just a matter of moving a few computers, but involves the entire production line.
If it is done, ‘Shengguang Machinery’ will definitely have a large displacement engine and a high-power transmission. A three-wheel production line will become a vehicle with more than four wheels.
More than 300 backbone technicians from all over the world are dividing their labors and carrying out their respective tasks. This is a learning process from the beginning, a lot of materials are released, and everyone is immersed in it.
The quarrel between the old and young engineers was nothing more than a small fragment in determining the technical route, and more and deeper intellectual exchanges are ongoing.
But this revolutionary progress is painful for Zhang.
He suffered from lack of culture and was always at the bottom of production. When he finally had an eyebrow and exhaled, he found that he seemed to be almost useless.
Computers sound very advanced. Doesn't it require workers like Lao Zhang?
Out of the workshop, a large transformer stood outside. This is specifically for powering high-power equipment in the workshop.
A group of electricians are spinning around the transformer, and it seems to replace the old guy who has worked for decades to improve the power supply capacity of the workshop. Because CNC production puts forward higher requirements for power supply.
Think of the Soviet-style thermal insulation sandbox that has been moved without knowing where to go. Lao Zhang feels that he is also like these antique things, obviously it can be used, but it can no longer keep up with the times.
"Oh, what can we veteran workers do in the future? It's only been a few days, so why don't you lose your job?"
Lao Zhang walked back and forth outside the workshop with a lot of thoughts. Listening to the sound of trucks on the road outside the workshop, a young apprentice ran in happily and shouted, "NC machine tools come, imported CNC machine tools!"
Hey ..., here's another pit stuff. Still let us old guys live?
