"Tell us what you think. The entire project was stalled because we were unable to provide sufficient strength of hydraulic pipes, which was a matter of life and death for the entire base. Don't be afraid to think too whimsically, just solve the problem. ”

In the pipe processing workshop of Hongqi Machinery Factory, Fu Xinmin, the workshop director with bloodshot eyes, held a cigarette that was about to burn his fingers, looked at the entire workshop in front of him, looked tired, and kept dozing dozens of men, women and children, and said with a tired face.

This meeting was held directly in the workshop.

Hydraulic pipes belong to the production scope of their workshop, which was originally a matching, and has not started for more than half a year.

Now when the first task is received, there is nothing the workshop can do.

Fu Xinmin has not closed his eyes for two days and two nights, and most of the people in the workshop have not rested for more than 24 hours.

"Director Fu, in the past few days, I have experimented with various methods, and even produced dozens of samples, but I can't meet the requirements. The maximum working pressure must exceed 60MPa in various environments, which is too demanding...... The same type of domestic excavator requires only 40MPa......" someone put forward an opinion.

Obviously, it was a dissatisfaction with the excavator development team.

It's just too much to ask.

"Director Fu, our hydraulic pipe can already withstand 60MPa, but the strength is not enough in various environmental changes, and the ultimate working pressure is also 55MPa, which is enough for excavators. ”

"The methods that we can think of in the whole workshop in the past few days have been verified, where are there any new ideas!"

Most people in the workshop can't bear it anymore.

It's not that everyone doesn't work hard, it's that the project team is too demanding.

The technical standards they can now achieve are among the top in the country, and the project team is still not satisfied.

"If you really can't do it, let's find a way to import it. Lao Fu, comrades have done their best these days. Tao Qinghong, the chief engineer of the workshop, was also bloodshot. "Our technical strength can reach the current level, which is already at a super level. ”

"Director Fu, we cleaners can't give any opinion on this matter, so let's go home! A small middle-aged woman in her forties said with two dark circles under her eyes and a dry voice.

What does technology development have to do with cleaners?

"Yes, it's useless for us to stay up here with logistics. "Not only the cleaners, but all the people in the entire workshop, one counts as one, and all of them are asked to use their brains and make suggestions.

In this case, more than a dozen feasible solutions have been verified by production, which is much higher than the technical standards they originally met, and still cannot meet the requirements of the project team.

The main thing is that it cannot be reached in terms of the ultimate working pressure resistance.

"If we can import, we won't be under so much pressure. The project team only gave us a month, from foreign imports, from negotiation to transportation, how can we get it in half a year?" Fu Xinmin shook his head.

Looking at the people in the entire workshop, they looked tired and their eyes were bloodshot, and Fu Xinmin also knew that it would not work like this.

Finally opened his mouth, "That's it, the production and technical staff stay, and the others go home and rest first." After everyone goes back, think of more ways to mobilize their families to help think together. ”

Even when he put the logistics staff back, he still asked them to mobilize their families to help figure it out.

Even if he knew it wouldn't work.

Better than nothing?

"Still in a meeting?" When the cleaners and warehouse management and other logistics staff just left, Xie Jianguo quickly stepped into the workshop, "Lao Fu, immediately organize technicians and staff to use thin stainless steel wire to tilt 45° braided hose, except for the inner rubber layer, the others are directly coated on the steel wire hose, and first make six layers of steel wire hoses......"

He didn't introduce too much, and directly asked Fu Xinmin to organize technical personnel and production personnel to conduct trial production.

Not even a technical argument.

"How thick is the stainless steel wire?" Tao Qinghong asked directly.

"0.1, 0.15, 0.15, 0.2 each trial production one, all six layers, you calculate the thickness of the glue. Xie Jianguo said.

"Mr. Xie, can this really work?" a technician in his thirties asked, "Don't let us work again in vain." ”

"That's right, I've been experimenting for the past few days, but none of them meet the requirements. ”

"Mr. Xie, even if it was almost before, there were very few cases of working in the extreme environment, right? ”

For the new plan proposed by Xie Jianguo, the technicians did not buy it.

"Don't say it's a lot, even if it's just a little bit, it's not good!" Xie Jianguo said solemnly. "In the world of technology, you can't settle for anything, it's pretty much enough. Every time it is almost the same, it will eventually cause a lot of difference! If the time is longer, this is the gap between generations! If every part is a little worse, how much worse will the assembly be? We have to compete with international competitors with rich experience. ”

It's not that everyone is unaware of the gap with foreign countries, and Xie Jianguo also knows that they have lost confidence.

"Whether it works or not, let's give it a try, there is no other way now, and the whole project can't continue until the hydraulic hose problem is solved." Xie Jianguo said, "I know everyone is very tired, hold on a little longer, work hard, the whole project is waiting." ”

During this time, the most stressful is this workshop.

No one would have thought that a small hydraulic hose would cause such a big obstacle to the whole project.

"The mold group, immediately check to see if there are these specifications of the mold, the rolling group raises the temperature of the furnace and prepares to supply the material, the wire drawing group is ready to produce steel wire, and the hose synthesis group is trying to find a way to solve the steel wire braiding plan...... Get started immediately!" Fu Xinmin didn't care whether the technology was feasible or not, and directly gave the order.

The whole workshop was accustomed to his style, and even when everyone was exhausted, the various teams moved quickly under his assignment.

In the early hours of the morning, the base should have fallen into silence, and most of the huge base fell into darkness, but there were still many workshops revealing a little light.

In the pipe shop, the rolling mill from the Czech Republic began to heat up, ready to roll the block of stainless steel ingots into long thick wires, and the die group began to grind the steel needles that met the specifications with the help of a microscope, and the electronic scales that can be accurate to 0.01g were also carefully brought out.

The diamond mold, with an inner hole of only 0.1 mm, cannot be measured, and the tolerance can only be controlled by the method of electronic weighing......

Workshop, sleepless all night.

It was getting dark outside, and the people in the workshop couldn't feel it at all.

At this time, all the preparations have just been completed.

Every process is started, whether it is a production worker or a technician, they are all walking and staggering, but no one complains, and the back process is waiting for the front material.

Xie Jianguo and Fu Xinmin have been calculating and deriving theoretical data with several technicians.

Without computer assistance, theoretical calculations are complex and enormous.

"Mr. Xie, according to the calculation results, the working pressure of 0.15 is the largest, and it can reach 64MPa under the ultimate working pressure, and it can even reach 72MPa under non-limit conditions!"

"It's just theoretical data, and it has to be produced and verified. Xie Jianguo was also excited, "If the experimental conditions can be met, our problem will be effectively solved." ”

He was even thinking about whether to rely on Xie Kai's reward of fifty yuan.

There is not much money left for the money I shared before.

When the first hydraulic pipe was manufactured, it was already two o'clock in the afternoon, and the workers in the previous process had already put back to rest, most of them were reluctant to leave, they waited in the workshop, wanting to determine whether they met the requirements as soon as possible.

Technicians are still fighting, and they have to carry out various tests on the hydraulic pipes produced.

If the test is qualified, the hydraulic pipe can meet the requirements.

If they meet the requirements, their stress will disappear.

"80 degrees Celsius, 68MPa working pressure...... The hose length is extended by 3%, which meets the requirements of use. ”

"-40 degrees Celsius, 70MPa working pressure...... The hose length is reduced by 4%, which meets the requirements of use. ”

"The maximum pulse pressure is 108MPa, the pipeline is ruptured, the hydraulic leakage is ......"

"At 2HZ pulse frequency, the temperature is 70 degrees Celsius, the working pressure is 85.4MPa, and the pipe rupture is ......"

The experimental data of one item after another were continuously reported to Tao Qinghong over time.

Every time he heard the results of an experiment, the smile on his haggard face increased.

Xie Jianguo was even more happy.

"Mr. Xie, it's a solution! Thanks to your plan. Fu Xinmin said to Xie Jianguo.

If it weren't for the plan provided by Xie Jianguo, they really didn't know how to solve it.

"We have to keep experimenting, and that's not enough. Especially in terms of service life, the working environment of the excavator is harsh, and the life and strength of the hydraulic pipe are not high, which will affect the work efficiency. What we provide is military products, and the quality must be guaranteed. Xie Jianguo said.

There was a hint of excitement in his words, but his heart was distressed.

The plan is effective, I said to Xie Kai last night that if it is feasible, reward him with 50 yuan, where do I get this 50 yuan reward for Xie Kai?

During this time, both projects worked overtime intensely, many times overnight, and almost all of his money was turned into cigarettes and alcohol and distributed to technicians who stayed up late.

I also hoped to borrow some more from Xie Kai, but I was quick to talk for a while......

"Mr. Xie, this has been successful, why are you unhappy?" Seeing that Xie Jianguo's face was not good-looking, Fu Xinmin asked on the side. "Is there still a problem?"

It's all already out, why is this new chief engineer so bad-faced?

The problem with the hydraulic hose was solved, and the follow-up experiments could be carried out.

"No problem. Hard work comrades!" Before the change, Xie Jianguo said without hesitation, comrades have worked hard, and I personally paid for everyone to drink or something.

Now, he didn't dare to say it.

If he has no money, he has no confidence, and even, he is worried about how to face his son, fifty yuan, which is not a small pressure.

You can buy 10 cigarettes!
