Chapter 175 The factory director’s little plan (fourth update)

"How long is this one?" The factory manager looked at the woven steel wire mesh sleeve and asked.

"The current design is 200 meters." Liu Hai has no choice. It is technically difficult to build a one-time molding production line. This is the production model of Batie's small workshop.

The high-pressure explosion-proof pipe is covered with several layers of mesh sleeves, and several sets of mesh sleeves of different specifications are installed on the equipment. For example, to produce 200 meters of explosion-proof pipes at a time, how many raw materials are added at one time to produce 200 meters, and then prepare for the second production.

This kind of small-scale production is suitable for today's big environment. The integrated automatic production line has high demand for electricity, raw material security, etc. If the voltage is accidentally unstable, the mold temperature may not be reached and it will be scrapped. .

This production is 200 meters at a time, even if there is a power outage or machine damage this time, there is not much material wasted.

Of course in total comparison.This kind of material wastes a lot of money. If it is produced in an integrated manner, as long as the production is stable, there will be no problem.

"Tsk tsk, good, good." Sun Aiguo was very satisfied. Now the motorcycle factory is ready to hand over all the production of motorcycle parts to other factories, but the other factories are not ready yet.

"Don't be too tired, don't worry." Sun Aiguo looked at Liu Hai again, and the more he looked, the more satisfied he became.

"Director, let's take a rest together when this is finished." Liu Hai planned to work overtime and finish this, then go back to the village to tell the village about the cabbage and take a look at his home.

"Just tell me if you need anything." Sun Aiguo patted Liu Hai's shoulder again.

The factory manager left, and was going to find trouble with the construction department, and hurriedly build the factory building, no matter what, seeing that the technology of this high-pressure explosion-proof pipe should be fast, don't wait until the technology is available, there will be no room.

After the research and development of the mesh sleeve machine, the next step is the production of high-pressure pipes, mainly the temperature of the nozzle mold, which already has rubber test data.

This design is simple, mainly for the subsequent debugging work. The process is probably that the feed port enters the nozzle mold at a certain temperature to form a pipe with a certain thickness.

When the first nozzle comes out, the first layer of net cover is immediately covered, and then a layer of rubber is covered immediately, and then the second layer of net cover is covered. The gap of this net cover should not be too dense, if it is too dense, the rubber cannot be combined.

The key is the temperature and the speed at which the nozzle mold comes out, so that several layers of coating can be fused with the rubber tube.

Several layers of netting must be completed on the nozzle mold of Jimi Factory. It takes less than ten seconds from the feed port to the discharge port. The nozzle temperature is related to the discharge speed.

If the material is discharged quickly, the temperature will definitely be low. If the material is discharged slowly, the temperature will be high and it will be easily deformed. Just like a hot melt pipe, it is necessary to ensure that the outer layer melts and the inner layer does not deform...  

The net sleeve production equipment can adjust the diameter of the net sleeve to adapt to high-pressure explosion-proof pipes of different diameters.

Liu Hai was tired of drawing in the office, so he came out to look at his sweet potatoes, potatoes, I don’t know if it’s the wasteland or the seeds, maybe it’s the burnt soil, each of the soil bags started to crack, this is the following There are sweet potatoes.

Liu Hai has been plowing sweet potato vines recently, and even drying sweet potato stalks when he has nothing to do. This stuff is delicious, modern export peninsula, small book.

After drying Liu Hai and others, they didn't take it home. After all, the land is collectively owned, so it's left here and handed over later.

"Section Chief, these sweet potatoes are growing a lot. If you look at the cracked mud, you can see the sweet potatoes." Li Dali and others also learned to farm, pointing to the cracked soil and said.

"Well, maybe it's because of this wasteland?" Liu Hai wasn't sure. Crops must have stable traits. This thing is only in its second year. Who knows whether it will be stable or unstable in the future.

Li Dali just said that. Li Dali didn't know anything about agriculture.

Liu Hai will wait until harvest time to talk about it. The teacher has a classmate who is engaged in agriculture. He asked his classmate to come and take a look. If it really doesn't work, he will promote it in the village next year.

In the next three years, natural causes accounted for part of the factors, and some people...

However, Hong Kong Island has opened up a new source of income, so maybe it won't be so embarrassing.

He was so busy that Liu Hai didn't even return to the courtyard once. Seeing that the equipment was gradually being completed, when Liu Hai went to Teacher Zhu's class on Sunday, he said hello to Sun Desheng and said that he would buy some meat or something in a few days.

Wang Hongmei was at home, and Liu Hai couldn't give her anything else, but she could still bring some meat when she went back. After all, the baby was hers, and she didn't lack this.

The 250 motorcycle was still known by Petrov and others, so Liu Hai just let them ride it.

In the laboratory building, the high-pressure pipe equipment has been manufactured and is being debugged.

"Li Dali, slow down." Inside the workshop, there was a pungent smell. Liu Hai was wearing a dust mask, mainly because it was inconvenient to wear a gas mask.

Li Dali and the others were also wearing dust masks, while Sun Aiguo and the others seemed to be fine and looked closely instead.

Li Dali reduced the speed of the nozzle by a gear, and Liu Hai watched the rubber particles being continuously conveyed in, and the rubber tube came out from the nozzle, and the speed of the rubber tube at the nozzle automatically took away the first layer of net sleeve, and made a Pressure facility to prevent the net from shrinking into a ball.

Originally, 200 meters of pipe were produced at a time, but after debugging the machine, the production was only [-] centimeters.

Sun Aiguo and others looked at the finished product, the four layers of steel mesh in the middle of the rubber tube, and the explosion-proof high-pressure tube. The main technical difficulty lies in the rubber tube, and the accessories at both ends are not technically difficult.

"That's it."

"Well, every time we produce, some materials are wasted." Liu Hai nodded.

Li Dali and the others shut down the machine, cleaned the nozzle, and then replaced the mesh cover to prepare for the second production. Of course, some waste materials can be recycled.

This kind of workshop-like equipment is not good at all. Of course, with this equipment, it can be handed over to other experts to optimize the combination and form an integrated production line.

An hour later, the second 200-meter high-pressure explosion-proof pipe from the factory was 180 meters qualified, and then the length of the explosion-proof hose needed was cut off and the metal fittings were installed.

"With this, can our [-]-ton hydraulic press be mass-produced?" Sun Aiguo looked at the pipe and asked.

"It is possible, but some parts must be forged or die-cast, otherwise the service life will be reduced."

"What's the matter, even if it only has one-third of the service life of imported products, how expensive are imported products."

"There must be more than that."

"Ah."

"You guys have to work harder here to produce different types of high-pressure explosion-proof pipes, and then I'll go to the ministry to check and accept them." Sun Aiguo can't wait to report. If your big brother doesn't sell it to us, then we have it too.

"Success." Liu Hai nodded, but in the later production, Liu Hai moved his mouth, because the factory manager transferred more than a dozen people from other workshops to learn technology.

In Sun Aiguo's report this time, he is going to ask the leaders for talents, lesbians with some culture, preferably young ones. Although Comrade Liu Hai is under the age of marriage, he should first arrange to work together and get acquainted with each other. Isn't that good? ?
