"The gasoline engine we are using now is a production line stocked by Modu. This thing is still the Soviet technology in the 1950s, and it is too old."
"Don't talk about the 1950s, if you look at it by American standards, this is their technology in the 1930s, at the level of World War II. Our current materials are not bad, and we can make a new one.
"You young people also want to follow Mr. Zhou to make new standards? Mr. Zhou doesn't understand, neither do you? The technology of this gasoline engine is old, but it's durable."
"Old comrade, you can't just look at the durability of the leather, but also consider the economy. Our current gasoline and materials are not bad, and the engine compression ratio can reach ten, which is much stronger than the current'five'."
"Yes, yes. Although our materials are not as good as abroad, they are also much stronger than decades ago. The cylinder wall of the engine can be made thinner, and the machining accuracy can be fully satisfied."
"You are all wrong. This single-cylinder gasoline engine has no potential to tap. I feel like copying Japanese technology. Why bother?"
In front of a square table surrounded by three generations of technicians, old, middle-aged and young, seven or eight people gathered around a few drawings and discussed in full swing.
Founder Zhang wore a faded overalls, frowned and listened to the discussion before leaving with a sigh. He walked out of the iron door of the workshop, exhaling a long breath, and feeling the relaxation that had been a long time ago.
Because he worked all year round in the harsh environment of mold foundry, Lao Zhang had a serious lung disease. Coughing ceaselessly every day can kill him every time.
When he arrived in Tianyang, he went directly to the hospital for X-rays. The doctors all shook their heads and said they had no choice but to treat conservatively. As a result, the logistics of'Holy Light' sent a bottle of'Boiled Water' for him to drink.
On the day he drank it, Lao Zhang coughed desperately in the toilet. Unlike previous painful coughs, he felt relaxed every time he coughed, coughing up a lot of thick phlegm and dirty blood.
After drinking'Boiled Water' for three days, Mr. Zhou also came to visit him in person. Both parties shook hands and chatted for a few words, and Lao Zhang felt as if he had taken his life back.
When sleeping on weekdays and nights, Lao Zhang coughed most of the time. The whole family suffers from lack of sleep. He slept peacefully for three consecutive days in Tianyang, but he was so happy.
Lao Zhang asked himself what magical medicine he was drinking
The "Holy Light" only replied, "Probably because Tianyang water and soil are more nourishing, it is easy to get better if you have any disease."
The illness is almost healed, so Lao Zhang has to work. The workshop he was staying in was an old workshop built in the 1960s by Tianyang Machinery Factory, with a beam-frame structure of more than 5,000 square meters, which was quite spacious.
'Shengguang Machinery' wants to engage in'snake swallowing elephant', but Tianyang Machinery Factory is too big, and currently only rents a few of its workshops for production.
When I first rented it, the workshop was messy, dirty and dark. Zhou Qingfeng immediately requested that the entire workshop be renovated, and the cleanliness of the workshop is clearly stipulated in the ISO standard.
Technical matters are difficult to handle, and cleaning must be done.
But I can’t learn how to build an airplane. Workers wear slippers to enter the workshop. It is also impossible to learn from Asan to build tanks, and the workers directly shed shit in the tank body.
As for Ah San's ability to build an aircraft carrier after three launches, Zhou Qingfeng was not worried. This is the quintessential knowledge of other people's nationalities, and you can't learn it if you don't drink enough water from the Ganges River.
The old workshop was originally equipped with dozens of old grandfathers' equipment, just like an industrial museum.
For example, the large heat-preserving sand box used for sand finding is a Soviet product, with huge volume and high energy consumption. As soon as this gadget was activated, the light bulbs in the entire workshop had to flash twice.
The quality of the thermal 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 is reduced to two hundred degrees before opening the box.
But the heat preservation time is long, the equipment turnover is slow, and the efficiency is low. Local small factories will open the box at five or six hundred degrees, exposing high-temperature castings directly to cold air.
The casting produced by this process seems to be no problem, but in fact it is equivalent to the overall quenching, the internal stress is extremely large, and the product quality is difficult to think about.
Many domestic machine tool factories do just that. They save trouble and reduce costs in production, and do not pay attention to details. The quality is not as good as that of Japan and Germany, and even Taiwanese products are inferior.
After the workshop was rented, the old Soviet antiques were moved away, and the overall space was cleaned and transformed.
Zhou Qingfeng ordered the goods again in Magic City. For example, the sand box does not have much technical content, it is a super-large "heat up fast", and the domestically produced one is also very easy to use.
Slowly increase the temperature to reduce the pressure on the power grid, and slowly decrease the temperature to ensure the quality of the castings. At the same time, heat insulation is done to reduce energy consumption. The equipment is enough to do this.
Many details in production need to be controlled by experienced workers like Lao Zhang. As a result, the rejection rate of cylinder castings for a 50-cc engine with a small displacement was reduced by half, which greatly improved the production speed and quality.
This cost naturally drops.
Just when Lao Zhang felt that he was worthy of Zhou's salary and treatment, a new trouble came.
'Holy Light' wants to upgrade technology, and the factory introduces computer-aided design and manufacturing. Not only the machining needs to be turned to CNC machine tools, but even the casting has to reduce the margin and reduce the machining time.
Although the CAD transformation of a small 50CC engine is really a fuss, Zhou Qingfeng's meaning is very simple-I won't only produce this small engine forever
The technical reserves that should be available are still to be increased.
CAD technology is actually the cooperation of many disciplines and processes such as mold, casting, machining, numerical control, computer design and so on. This is not just a matter of moving a few computers, but the entire production line.
If it is done, "Shengguang Machinery" will definitely be equipped with a large displacement engine and a high-power transmission. A production line with three wheels will become a vehicle with more than four wheels.
More than 300 backbone technicians from all over the world are dividing the work and doing their own work. This is a process of learning from scratch. A large amount of information is distributed, and everyone is immersed in it.
The quarrel between the old, middle-aged and young engineers was just a trivial piece of determining the technical route, and more and deeper wisdom exchanges are underway.
But this revolutionary progress is very painful for Lao Zhang.
He suffers from the lack of culture and has always been at the bottom of the production. Finally, when he was elated, he found that he seemed to be out of use.
The computer sounds very advanced. Does it eliminate the need for workers like Lao Zhang
Walking 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, seemingly about to replace this old guy who has been working for decades and improve the power supply capacity of the workshop. Because CNC production puts forward higher requirements for power supply.
Thinking about the Soviet-style thermal insulation sand box that has been moved to nowhere, Lao Zhang feels that he is like these antique gadgets. It is obviously still usable, but it can't keep up with the times.
"Oh, what can we veteran workers do in the future? It's just a few days after a good day. Is it possible that we will lose our jobs?"
Lao Zhang walked back and forth outside the workshop, worrying. Hearing the sound of trucks on the road outside the workshop, a young apprentice happily ran in and shouted: "CNC machine tools are here, imported CNC machine tools!"
Alas..., there's another deceptive thing. Would you let us old guys live
