"The gasoline engine we are using now is the production line of Modu's inventory. This thing is still the technology of the USSR in the fifties, it is too old. ”

"Don't talk about the fifties, if you look at it by American standards, this is their technology in the thirties, completely World War II level. Our materials are not bad now, and we can make a new one. ”

"You young people also want to follow Mr. Zhou to make a new standard? Mr. Zhou doesn't understand, and you don't understand either? Although the technology of this gasoline engine is old, it is durable. ”

"Old comrade, you can't just look at the durability of the leather, but also take into account the economy. Our current gasoline and materials are not bad, and the engine compression ratio can be completely ten, which is much stronger than the current 'five'. ”

"Yes, yes. Although our materials are not as good as those of foreign countries, they are also much stronger than they were a few decades ago. The engine cylinder wall can be made thinner, and the machining accuracy can be fully satisfied. ”

"You're all wrong. This kind of single-cylinder gasoline engine has no potential to be tapped, so I think I should simply copy the Japanese technology. Why bother? ”

In front of a square table, three generations of old, middle-aged and young technicians were around, and seven or eight people were discussing a few drawings.

Lao Zhang, a sand turner, wore a faded overall, frowned and listened to the discussion, and left with a sigh. He walked out of the tin door of the workshop, exhaled a long breath, and felt the relief he had not felt for a long time.

Due to working in the harsh environment of the mold sand turning line all the year round, Lao Zhang has serious lung disease. Coughing constantly every day, every time it can kill him.

When I arrived in Tianyang, I went directly to the hospital to take an X-ray. The doctors shook their heads and said that there was no way to do it, so they could only treat it conservatively. As a result, the logistics of the 'Holy Light' sent a bottle of 'boiled water' for him to drink.

On the day he drank it, Lao Zhang was coughing desperately in the toilet. Unlike his previous painful coughs, this time he was a little lighter with each cough, coughing up a lot of thick phlegm and dirty blood.

drank 'boiled water' for three days in a row, during which Mr. Zhou also came to visit him in person. The two sides shook hands and chatted a few words, and Lao Zhang felt as if he had picked up a life.

Sleeping on weekdays and nights, Lao Zhang coughs most of the time. The whole family is followed by sleep deprivation. slept peacefully for three days in a row in Tianyang, but he was very happy.

Lao Zhang asked himself what kind of miracle medicine he was drinking?

The 'Holy Light' side only replied, "Probably because Tianyang water and soil are more nourishing, and it is easy to get better if there is any disease." ”

The illness is almost cured, and Lao Zhang has to work. The workshop he stayed in was an old factory building built in the 60s of Tianyang Machinery Factory, with a beam structure, 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 only a few of its factories are currently rented 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 ISO standard has clear provisions on the cleanliness of the plant.

It's hard to get the technical things done, but the cleaning things have to be done.

You can't learn how to build an airplane, and the workers wear slippers into the workshop. You can't learn how to build a tank, and the workers directly in the tank hull.

As for Ah San's ability to launch three times and not build an aircraft carrier, Zhou Qingfeng is not worried. This is a national mastery, and you can't learn it if you don't drink enough water from the Ganges.

There were originally dozens of grandfathers' equipment in the old workshop, like an industrial museum.

For example, the large insulated sand box used for sand turning is a Soviet product at first glance, with a huge volume and high energy consumption. As soon as this thing is activated, the light bulbs in the entire workshop have to flash twice.

The quality of the insulation sand box is related to the quality of the casting. In particular, the slower the cooling process of large castings, the better, and it is necessary to keep warm in the sand box for a long time, and then open the box after cooling to 200 degrees.

However, the heat preservation time is long, the equipment turnover is slow, and the efficiency is low. Small local factories will open the box at five or six hundred degrees, so that the high-temperature castings are directly exposed to cold air.

The castings produced by this process seem to be fine, but in fact they are equivalent to integral quenching, and the internal stress is extremely high, and it is difficult to think about the quality of the product.

Many domestic machine tool factories do this, the production of the map to save trouble and reduce costs, do not pay attention to details, the quality is not as good as Japan and Germany, even Taiwan goods are not as good.

After the workshop was rented, the old Soviet antiques were removed, and the overall space was cleaned and renovated.

Zhou Qingfeng re-ordered the goods in the magic capital. For example, the sand box has no technical content, it is a super-large 'hot fast', and the domestic one is also very easy to use.

Slow heating to reduce the pressure of the power grid, slow cooling to ensure the quality of castings, and at the same time do a good job of thermal insulation and heat preservation, reduce energy consumption. That's all it takes for the device.

Many details in production need to be controlled by experienced workers like Lao Zhang. As a result, the scrap rate of cylinder castings for engines with a small displacement of 50 cc has been reduced by half, which has greatly improved the production speed and quality.

This cost naturally goes down.

Just when Lao Zhang felt that he was worthy of the salary and treatment given by Mr. Zhou, a new trouble came.

'Holy Light' wants to carry out technological upgrading, and the factory introduces computer-aided design and manufacturing. Not only machining should be turned to CNC machine tools, but even casting should be carried out with low margins to reduce machining time.

Although it is really a big fuss to carry out CAD transformation of a small 50CC displacement engine, Zhou Qingfeng's meaning is very simple - I will not only produce this kind of small displacement engine forever?

The technical reserves that should be there still need to be on.

CAD technology is actually a combination of many disciplines and processes such as molding, casting, machining, numerical control, computer design, etc. It's not just a matter of moving a few computers, it's about 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 that makes three wheels will become a vehicle that makes more than four wheels.

More than 300 backbone technicians from all over the world are dividing labor and carrying out their own work. It's a learning process from scratch, with a lot of information being handed out and everyone immersed in it.

The quarrel between the old, middle-aged and young engineers was just a small piece of the technical route that was not worth mentioning, and more and deeper exchanges of wisdom were underway.

But this revolutionary progress was painful for Lao Zhang.

He suffered the loss of no culture, and he has always been at the bottom of production, and finally had a time to raise his eyebrows, but found that he seemed to be almost useless.

The computer sounds very advanced, but with it, there is no need for workers like Lao Zhang?

Walking out of the workshop, there was a big transformer standing outside. This is specifically designed to supply power to high-power equipment in the workshop.

A group of electricians are circling around the transformer, as if they want to replace the 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 insulated sand box that has been carried and missing, Lao Zhang feels that he is also like these antique things, which can still be used, but he can't keep up with the times.

"Oh, what are we old workers going to do in the future? It's only been a few days, is it hard to lose your job? ”

Lao Zhang walked back and forth outside the workshop, preoccupied. I heard the sound of trucks on the road outside the workshop, and a young apprentice happily ran in and shouted: "CNC machine tools are coming, imported CNC machine tools!" ”

Alas...... there's another trick on you. And don't let us old guys live?
