Siheyuan: Domineering life

Chapter 412 Technical transformation successful

At noon, Yang Jun drove out of the factory.

When he came back, there was an extra jar on the car.

He drove the car directly to the downstairs of the hospital next door, and then called someone to deliver the jar to Yi Qiushui's office.

In the past few days, he had to avoid Ding Qiunan to avoid seeing her resentful eyes.

The transfer order from above has been issued, and there are other candidates for the two vice-presidents, who will take office in a few days.

He won't go to Yi Qiushui's place to eat in the past few days. He will go there after the dust has settled and Ding Qiunan has lost his thoughts.

Of course, when he went back, he didn't forget to stop by the security department and scold Wang Erwa like crazy.

When he was about to get off work in the afternoon, Han Shengli sent someone to call him and told him that the lathe had been modified and asked him to come and take a look.

When Yang Jun heard this, he immediately put down all the work in his hands and went to the workshop.

This is a matter related to his political performance and must be treated with caution.

When I came to the workshop, I saw a group of people surrounding the machine tool.

They all had smiles on their faces and seemed to have tested the machine.

"How? Can it be used?"

Yang Jun raised his hand to stop those who wanted to say hello to him and asked directly.

"It works, we've been running it for 10 minutes."

Han Shengli looked excited, patted the modified machine tool and said, "We tested it just now, and it was much faster, much better than originally expected."

Yang Jun looked at the modified part with his hands behind his back.

Between the lathe gearbox and the feed box, there are some extra gears.

These gears are temporarily made by eighth-level workers in the factory. They have beautiful appearance, suitable size, and the fit between the various parts is very good.

Next, Yang Jun looked at another improvement, which was the addition of two low-power motors on both sides of the lathe.

Although, Yang Jun didn't know what the motor was used for, it must be related to its operating efficiency.

"Director, this is a servo motor."

Han Shengli saw that Yang Jun kept staring at the two motors, so he explained.

"servo motor?"

Yang Jun was startled when he heard this and asked, "Do we have such a thing in our factory?"

He remembered that the earliest servo motor technology only appeared in the 80s, but he did not expect that such a thing would be available now.

"Yes, it was imported from abroad before, but it was too expensive. Later we started to develop it ourselves. This motor was developed by the Third Research Institute." Han Shengli explained.

"Is this motor expensive?" Yang Jun asked.

Han Shengli was startled for a moment and his face looked a little ugly.

"Not only is it expensive, it's extremely expensive. One motor costs more than 300 yuan."

"More than 300 yuan?"

When Yang Jun heard this, he was immediately startled.

Even in later generations, you could buy a good motor for 300 yuan, but in this era, asking for more than [-] yuan is no different from robbing it.

However, it’s no wonder that the asking price is so high. The new product has not yet been mass-produced, so the price must be high.

However, Yang Jun then thought, if this transformation and upgrade can be successful, it will be worth spending this small amount of money.

"Okay, don't worry about the motor for now, get ready to start it up."

Yang Jun waved his hand and signaled them to start testing.

"Okay, director."

Han Shengli responded, then looked back at the 50-year-old employee next to him and said,

"Master Zhao, come and turn on the phone."

Professional things are left to professional people.

Although Han Shengli is an engineer, when it comes to lathe skills, any third-level worker in the factory is better than him.

The Master Zhao in front of him is the only eighth-level lathe in the factory. Yang Jun knows him. His name is Zhao Wencheng. When he went to the arsenal for inspection before, it was this Zhao Wencheng who produced qualified pipe fittings.

When Zhao Wencheng heard this, he didn't say anything and just nodded.

He rolled up his sleeves, spit in his palms, rubbed his hands together a few times, and then started to operate the machine tool.

Everyone retreated far away, staring at Zhao Wencheng.

Zhao Wencheng touched the power switch and pressed it hard.

"Buzz!"

The moment the power is turned on, the spindle begins to rotate at high speed.

Colleagues who rotate the main shaft have seen the bridge gear driving the polished rod next to it. The worm on the polished rod drives the turbine and the longitudinal cams on the two turbines... Using line switches and electromagnets, the semi-finished column head components placed on the angle iron are quickly The spring chuck in front of the spindle is fixed, and then the longitudinal knife is fed to the specified position.

The modified courtyard and action path may sound a bit complicated, but the actual operation is completed in an instant.

"Z!"

There was a sharp sound of metal cutting.

Dark blue iron filings peeled off in circles, and a rough-turned pig's head was quickly finished cutting.

"Click!"

The lever pushes the transverse turning tool forward, the processed column head part is cut off, the spring chuck is released, and the waste material also rolls down into the iron box located in the spring chuck.

"Buzz!"

After a sound, the lathe stopped.

Zhao Wencheng turned off the power, picked up the workpiece in the iron box with pliers and handed it to Han Shengli and said,

"Han Gong, please measure the accuracy."

Han Shengli took the pliers and placed them on the toolbox next to him.

Then take out the vernier caliper. A micrometer is not needed for this kind of rough turning workpiece.

After careful measurement, Han Shengli showed a smile on his face.

He turned back to Yang Jun and said, "Director, the size is qualified."

"Then...this is considered a success." Yang Jun asked.

"It worked, very successfully."

Han Shengli looked sure, and then said: "It used to take at least 3 minutes to complete a workpiece like a car, but now it only takes tens of seconds to complete. This efficiency improvement is not even a little bit."

When Yang Jun heard this, he was shocked.

Trying to control the joy in his heart, he then said with his hands behind his back: "The quality is okay, but we still have to see how the efficiency is."

"Buy a few more cars and see what the pass rate is."

Although Yang Jun doesn't understand technology, he still understands the most basic things.

The speed has increased, but a series of problems will also arise.

In the production of workpieces, we must not only pursue efficiency, but also pursue quality.

If the pass rate of the workpieces produced is very low, it is useless no matter how fast the speed is.

Seeing that Yang Jun affirmed his work, the excitement on Han Shengli's face never dissipated.

After looking at his watch, he said: "Director, there's still half an hour before get off work ends. Why not use this time to see how much can be processed?"

"Yes." Yang Jun waved his hand and said, "I will do as you say."

After receiving the instruction, Han Shengli signaled Zhao Wencheng to continue the test.

Later, several employees helped put all the materials on the angle iron rack for feeding materials.

Several employees patted Zhao Wencheng on the shoulder and said: "Old Zhao, come on, it's up to you."

"Master Zhao, come on."

Everyone is very excited. They hope that the machine tool can be successfully modified more than anyone else. After all, this is the result of their whole day's work.

Then, the machine starts up again and starts a new round of processing procedures.

One……

two...

three...

……

ten...

As the processed parts were cut off from the chuck connection one by one, the speed was so fast that the master craftsmen who had been lathes all their lives couldn't help but gasp.

Generally speaking, even rough machining of a chuck requires an experienced master to repeatedly load the chuck with raw materials, adjust the coaxiality, and constantly adjust the feed rate and back cutting amount during processing, and then pass the iron Needless to say, it is time-consuming and labor-intensive to judge the cutting force and whether the cutting temperature is within the normal range by looking at the chips.

This time, Huang Zhiqiang's automated improvement drawings were used to set everything in advance, eliminating a lot of tedious manual steps. This processing efficiency greatly increased the workload.

40, 41, 42...

As Zhao Wencheng continued to process, everyone also silently counted the processed workpieces in the iron box.

At the same time, Han Shengli kept looking at the time.

It had only been twenty minutes, and he was already feeling a huge shock in his heart.

More than 10 parts can be processed in 40 minutes. This is definitely the fastest record in the steel rolling mill.

In fact, the one who was most shocked was Zhao Wencheng.

He has been a lathe for decades, and he knows better than anyone the time required for normal machining.

Parts that used to take two to three minutes to process can now be completed in just tens of seconds. This kind of efficiency can be said to be unprecedented.

If production can continue at this rate, the work efficiency will be more than six times the original.

"Director, what do you think of this efficiency?"

Han Shengli asked.

"just OK."

Yang Jun has never seen anything like this. In later generations, there are many machine tools that are much faster than this.

These guys can't boast, they have to knock a few times from time to time.

They had just made some achievements, and their tails were raised so high. If they were to praise them a few more words, they would not be able to go to heaven.

When Han Shengli heard this, his face twitched a few times, and the smile on his face suddenly disappeared.

He cursed in his heart, you call this just okay, I have never seen you dislike that kind of speed before.

Of course, he didn't dare to say it openly. Leaders always have this kind of face. They say high-profile things but don't do practical things.

"Three ten minutes."

Following Han Shengli's greeting, Zhao Wencheng also stopped processing.

After the machine stopped, a group of people rushed over.

Pour the parts processed in the iron box onto the tool box and start counting how many are processed.

"68."

As soon as this number came out, everyone cheered immediately.

68 is the number they usually process. Unexpectedly, after the machine tool was upgraded, it only took half an hour to do it.

This greatly refreshed their understanding.

"Congratulations, Huang Gong."

Everyone expressed their congratulations to Huang Zhiqiang.

Even though the upgrade plan was hosted by chief engineer Han Shengli, everyone knew that this plan was proposed by Huang Zhiqiang.

Huang Zhiqiang looked at everyone with a smile on his face and kept saying: "I don't dare, I don't dare. This is all thanks to everyone. I just came up with an idea. It's not worth mentioning."

After Yang Jun's advice, Huang Zhiqiang's attitude became much more modest.

He also realized that Yang Jun was right, this kind of credit belongs to the collective and no one can monopolize it.

On the other hand, Han Shengli, instead of being angry, patted Huang Zhiqiang on the shoulder and said sincerely,

"Huang Gong, please stop being modest. Your contribution is obvious to all. Don't worry, he is yours and can't escape."

Han Shengli said to Yang Jun: "Director, Huang Gong has made such a great contribution, do you think this year's model workers are...hehe."

Yang Jun smiled and said: "It's too early to say this now. After the machine is confirmed to be ok, I will suggest to several other leaders that the model worker quota be given to Huang Gong."

"That's right, what the factory director said is that it's too early to talk about this now. It won't be too late to wait until it's confirmed that there is no problem with the machine."

Yang Jun turned around and said to the masters who were measuring the accuracy of the workpiece,

"Has the passing rate come out?"

"There are only a few left, and the results will be out soon."

While measuring the accuracy, a master looked back and said: "These first parts are all qualified. Even if the following parts are not tested, it will not affect the pass rate."

Yang Jun didn't say anything and waited patiently.

Monkey Sun learned from the scriptures and experienced ninety-nine and eighty-one hardships, including this moment.

Soon, the remaining parts were measured, and the master just now said excitedly,

"Factory director, the pass rate is 100%. I have been working for a lifetime and have never had such a high pass rate. Today I saw that my life is worth it."

As soon as he finished speaking, everyone immediately cheered.

This passing rate was beyond everyone’s expectation.

No one expected that such a fast speed could maintain such a high pass rate.

Even Yang Jun was excited. This was a real achievement. From now on, when he goes to meetings in the department, he can definitely slap the table with the senior leaders and ask for orders.

"General Engineer Han, inform the comrades on the night shift to continue testing and ensure the success of this upgrade," Yang Jun said.

"Director, don't worry. I have arranged for two experienced masters to conduct tests tonight to ensure that there will be no problems." Han Shengli said.

Yang Jun glanced at the crowd around him, then pulled him aside and whispered,
"Also, the upgrading of the machine tools must be kept secret for the time being. In addition, just in case, the drawings must be handed over to the security department for safekeeping."

"I understand, factory director, I'll take care of this."

Han Shengli is an old man in the technical department, so he naturally knows the power of this.

This reform can be said to be of great historical significance and has a major milestone role in the reform of machine tools across the country. Naturally, he does not dare to take it lightly.

The machine tool upgrade drawings are related to the national economy and people's livelihood. If there are any mistakes, he will never redeem them.

　Today is the editor-in-chief’s recommendation.

　　Please give me some support, thank you.
