At noon, Yang Jun drove out of the factory.

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

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

In the past few days, he has to avoid Ding Qiunan, so as not to see her resentful eyes.

The above appointment has been issued, and the two vice presidents will be selected by someone else, who will take up their posts in a few days.

He didn't go to Yi Qiushui's place to eat these days, and when the dust settled, Ding Qiunan lost his mind, and then he went over.

Of course, when he went back, he didn't forget to go to the security department by the way to scold Wang Erwa.

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

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

This is a matter of his political achievements, and it must be treated with caution.

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

They were all smiling and seemed to have tested the machine.

"How? Will it work?"

Yang Jun raised his hand to stop those who wanted to greet him, and asked directly.

"Yes, we've been running for ten minutes."

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

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

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

These gears are all temporarily made by the eighth-level workers in the factory, and they are beautiful in appearance, the right size, and the bite between the parts is very good.

Next, Yang Jun looked at another improvement part, which is to add two low-power motors on both sides of the front and rear of the lathe worker.

Although, Yang Jun doesn't know what the motor is for, it must be related to the efficiency of operation.

"Factory director, this is a servo motor."

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

"Servo motors?"

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

He remembers that the earliest servo motor technology only appeared in the eighties, and he didn't expect it to exist now.

"Yes, it was imported from abroad before, but it was too expensive, and then we started to develop it ourselves, and this motor was researched by the Third Research Institute." Han Shengli explained.

"Is this motor expensive?" Yang Jun asked.

Han Shengli was stunned for a moment, his face was a little ugly,

"It's not just expensive, it's just expensive, a motor costs more than 300 yuan."

"More than 300 yuan?"

When Yang Jun heard this, he was immediately startled.

A 300 yuan motor can be bought in the future, and the price of more than 300 yuan in the current era is no different from grabbing.

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

However, Yang thought about it, if this transformation and upgrading can be successful, it is still worth spending this little money.

"Alright, leave the motor alone, get ready to turn it on."

Yang Jun waved his hand and motioned for them to start testing.

"Okay, Director." ….

Han Shengli answered, and then looked back at the fifty-year-old worker next to him and said,

"Master Zhao, you come and turn it on."

Professional things are left to professional people.

Don't look at Han Shengli as an engineer, but when it comes to lathe technology, any third-level worker in the factory is better than him.

This Master Zhao in front of him is the only eighth-level lathe worker in the factory, Yang Jun knows him, his name is Zhao Wencheng, when he went to the arsenal to inspect before, it was this Zhao Wencheng who made qualified pipe fittings.

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

I rolled up my sleeves and put it in the palm of my hand

He spat and rubbed his hands together a few times before starting to operate the machine.

Everyone withdrew from the distance, staring at Zhao Wencheng with their eyes.

Zhao Wencheng touched the power switch and pressed it suddenly.

"Hum!"

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

The spindle rotates to the colleague, and I have seen the bridge gear, which drives the smooth rod next to it, and the worm on the smooth rod drives the turbine and the longitudinal cam on the two turbines,...... By means of a linear switch and an electromagnet, the semi-finished stigma element placed on the angle iron is quickly fixed by a spring chuck in front of the spindle, and then the longitudinal knife is fed to the specified position.

The modified yard and the movement path sound a bit complicated, but the actual operation is completed in an instant.

"Z!"

A sharp metal cutting sound sounded.

The dark blue iron filings peeled off in circles, and a rough pig's head was quickly cut.

"Click!"

The lever pushes the transverse turning tool forward, the machined column head is cut off, the spring chuck is released, and the scrap is rolled down in the iron box located at the spring chuck.

"Hum!"

After a bang, 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,

"Han Gong, measure the accuracy."

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

Then take out the vernier caliper, this kind of rough workpiece does not need a micrometer.

After carefully measuring it, a smile appeared on Han Shengli's face.

turned back to Yang Jun and said, "Factory director, the size is qualified."

"That...... That's a success." Yang Jun asked.

"It worked, it was very successful."

Han Shengli looked affirmative, and then said: "In the past, it took at least three minutes for a workpiece like a car, but now it only takes tens of seconds to complete, which is not a half-star improvement in efficiency."

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 fine, but let's see how efficient it is."

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

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

The speed is up, but it comes with a series of problems.

In the production of workpieces, it is not only about efficiency, but also about quality.

If the quality rate of the workpiece produced is very low, it is useless to be fast.

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

After looking at his watch, he said, "Factory director, there is still half an hour before the end of work, why don't you use this time to see how much can be processed?" ….

"Hmm."

Yang Jun waved his hand and said, "Just do as you say."

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

Subsequently, several employees helped to put all the materials on the angle iron shelf for feeding.

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

"Master Zhao, come on."

Everyone was excited, and more than anyone else wanted the machine to be a success, because it was the result of a day's work.

Subsequently, the machine starts again and a new round of processing procedures begins.

One......

Two......

Three......

……

Ten......

As the processed parts are cut off and rolled off from the chuck connection one by one, the speed is so fast that the masters who have been lathe workers all their lives can't help but smack their tongues.

Generally speaking, even if it is rough processing of a chuck, it is necessary for an experienced master to repeatedly use the chuck to load raw materials, adjust the coaxiality, and constantly rest the feed rate and the amount of back eating when processing, and then judge the cutting force and whether the cutting temperature is in the normal range through the eyes of the iron filings, which is time-consuming

Needless to say, force.

This time, Huang Zhiqiang's automation improvement drawings were used to set everything in advance, saving a lot of manual operation and cumbersome steps, which greatly improved the processing efficiency.

40，41，42……

As Zhao Wencheng kept processing, everyone also silently counted the processed workpieces in the iron box.

At the same time, Han Shengli was also constantly watching the time.

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

More than 40 parts were processed in 20 minutes, which is definitely the fastest record in a rolling mill.

In fact, it was Zhao Wencheng who was most shocked.

He is a decades-old turner, and he knows better than anyone how long it takes to machine properly.

Parts that used to take two or three minutes to complete can now be completed in only a few tens of seconds, which is unprecedented in efficiency.

If we can continue to produce at this rate, the efficiency will be more than six times that of the original.

"Director, how efficient do you think this is?"

Han Shengli asked.

"Make do with it."

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

These guys can't boast, they have to be tapped a few times in a while.

Just made some achievements, and the tail is so high, if you praise them a few more words, you won't be able to go to heaven.

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

He slandered in his heart, you call this improvised, I haven't seen you dislike that kind of speed before.

Of course, he didn't dare to say it openly, the leaders all had this face, and they would say high-profile things, but they didn't do practical things.

"Thirty minutes coming."

As Han Shengli greeted, Zhao Wencheng also stopped processing.

When the machine stopped, a crowd rushed over.

I poured the machined parts from the tin box onto the toolbox and began to count how many were machined.

"Sixty-eight."

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

Sixty-eight is their usual machining number, but they didn't expect that after the machine upgrade, it would only take half an hour to do it. ….

This has greatly refreshed their cognition.

"Congratulations, Huang Gong."

Everyone congratulated Huang Zhiqiang.

Don't look at the upgrading plan presided over by Chief Engineer Han Shengli, but everyone understands in their hearts that this plan was proposed by Huang Zhiqiang.

Huang Zhiqiang looked at everyone with a smile on his face, and kept saying, "Don't dare, don't dare, it's all everyone's credit, I just put forward an idea, it's not worth mentioning."

After Yang Jun's order, Huang Zhiqiang's attitude was 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, he patted Huang Zhiqiang's shoulder and said earnestly,

"Huang Gong, don't be modest, your credit is obvious to all, don't worry, it should be yours and he can't run."

Han Shengli said to Yang Jun: "Factory director, Huang Gong has made such a great contribution, do you see if this year's model worker is ...... Hey, hey."

Yang Jun said with a smile: "It's too early to say this, after the machine confirms that there is no problem, I will suggest to several other leaders that the quota of model workers be given to Huang Gong."

"Yes, yes, what the factory director said is that it's too early to talk about this, and it's not too late to talk about it when it's confirmed that the machine is fine."

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

"Is the pass rate out?"

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

While measuring the accuracy, a master turned around and said, "The first parts are all qualified, even if the latter ones are unexpected, it will not affect the pass rate."

Yang Jun didn't speak, and waited patiently.

Sun Monkey

The son learns from the scriptures, and he has experienced ninety-nine eighty-one difficulties, and it is not bad for a while.

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

"Factory director, the pass rate is 100%, I have worked for a lifetime, and I have never won such a high pass rate, today I saw that this life is worth it."

As soon as the words fell, everyone immediately cheered.

This pass rate was unexpected.

With such a fast speed and such a high pass rate, no one thought of it.

Even Yang Jun was excited, this is a real achievement, and when he goes to the ministry for a meeting in the future, he can slap the table with the big leader to ask for an order.

"Chief Engineer Han, inform the comrades on the night shift and let him continue to test, and we must ensure the success of this upgrade." Yang Jundao.

"Factory director, don't worry, I have arranged two experienced masters to conduct a special test in the evening, so as to ensure that there will be no mistakes." Han Shengli said.

Yang Jun glanced at the crowd around him, then pulled him aside and whispered,

"Also, the upgrade of the machine tool is to be kept secret for the time being, and in addition, the drawings must be handed over to the Security Section for safekeeping, just in case."

"Got it, factory director, I'll do 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 a reform of great historical significance, and has a major milestone role in the reform of machine tools in the country, and he naturally does not dare to take it lightly.

The machine tool upgrade drawings are related to the national economy and people's livelihood, and once there is a mistake, he will not be redeemed.
