Big Country Intelligent Manufacturing

Seeing Xu Zhenming's serious look, Ma Jimin smiled bitterly and shook his head.

He can't help it, who calls his disciple the boss!However, he was very careful in doing things. He sent the damaged parts and related parts to the machine repair shop with vehicles so that Xu Zhenming could refer to them when surveying and mapping data.

Surveying and mapping workpieces is a necessary quality for mechanical engineers.

Xu Zhenming is an experienced mechanical man, so he can do this kind of work.In addition, Ma Jimin considered the data more comprehensively and had the data of the supporting parts for reference. It took him a day to map out the data of the damaged gears, transmission shafts and some structural parts.

Of these workpieces, gear mapping is the most difficult.If the mapping is not accurate, the modulus and number of teeth of the gear will certainly not be wrong.However, there may be problems with the engagement of the new gear and the matching gear.When the gear is running at a high speed, the teeth will get fatigued easily, and there will be breakdowns or tooth skipping.

When they got the processing drawings of these workpieces, Li Quan, Director Sun and others were very worried.They asked Xu Zhenming again and again: "Xiao Xu! Should we process it according to this set of drawings?"

Seeing their expressions, Xu Zhenming was speechless.He secretly smiled in his heart: "Master! Master! I'm a senior engineer. If there is any problem with such simple surveying and mapping, how can I still have a mixed meal?"

Thinking of this, he laughed and said: "Just process according to this set of drawings! Even if I make a mistake, I will only lose a little material cost and processing cost, the loss is not big!"

Xu Zhenming is the boss with a big mouth!Li Quan and others had to process machine tool parts according to his requirements.

As a result, the machine tool workers in the machine repair shop are not enough!

Therefore, Xu Zhenming asked Director Liu to come forward and recruit some machine tool workers from those who were not laid off in the machine repair shop.

Li Dayan was not selected.

He went to Xu Zhenming's office in private and begged Xu Zhenming with a wry smile: "Boss Xiao Xu! You can let me go to the machine tool! Otherwise, when can I pay your five hundred yuan?"

In fact, the five hundred yuan Xu Zhenming lent Li Dayan didn't intend to take it back at all, it was just to give Li Dayan a face.Thinking of this, he smiled and said: "The operation of the small universal milling machine in our workshop is the simplest. If you really want to use the machine tool, it is not impossible. But, can you suffer?"

"I can!"

Li Da nodded his head firmly.

As the saying goes, the prodigal son will not change his money.Xu Zhenming is going to give Li Dayan a chance, and maybe it can help him follow the right path, which is also a great thing for Ji De!

Seeing Xu Zhenming's agreement, the corners of Li Dayan's mouth twitched more severely, looking a little hideous and terrifying.Sure enough, he was a man with a temper, and he began to operate a small universal milling machine seriously, running in four shifts and three shifts in accordance with the rules set by Xu Zhenming, shifting shifts non-stop.

However, his recent actions are very weird, and he doesn't want to go home after the shift, and he wanders around the factory.

Xu Zhenming has solved the employment of more than 20 people in the machine repair workshop, which is considered a great deed.When the parts of the first lathe were produced, he personally came to the light workshop of the Honghe Town Agricultural Machinery Factory to prepare to assemble the dismantled small car.

"Naruko! Let me do it!"

Li Quan didn't worry, rolled up his sleeves and prepared to be the main performer.He is an experienced mechanic and fitter, and has a good time with "three knives and one hammer".

The fitter has such words as "three knives" and "a hammer"!

Of the three knives, one is a file, one is a saw, and the other is a scraper.Experienced fitters can file workpieces with an accuracy of 0.01 mm with a file; they can use a saw blade to cut materials that are no worse than a saw; they can use a scraper to repair turbine blades with an accuracy of 0.005 mm.

Another hammer head is a round sledgehammer!The wheel sledgehammer is very particular about assembling the work piece. If you smash the mark on the work piece, you have already failed.

However, these technologies are gradually being lost with the popularization of various machine tools and hydraulic tools.In addition, young fitters are reluctant to practice these manual techniques, which further promotes the loss of these techniques.

Xu Zhenming learned to "three knives and one hammer" under the strict requirements of Li Quan.Before he was reborn, he was well-known in the industry for his three-knife technology. He was once asked by a super large steel company to help. Ten thousand dollars a day without a counter-offer was used to scrape copper bearings for other large motors.

Therefore, he also knew Li Quan's skills, so he was naturally relieved.Thinking of this, he smiled and said: "Master! You are the master, I will give you a hand!"

The first machine tool was an old 6130 general car, and the drive shafts, gears and bearings were worn out.Xu Zhenming surveyed and mapped the data, redesigned the drawings, and produced a new set of accessories.

The bearings used are the products of the domestic brand "Havalo", which are directly purchased from the electromechanical trading company; the main drive shaft is used alloy forgings, which are processed in the machine repair shop; the same is the transmission gear, all in the machine repair shop Produced in accordance with the picture.

The first step is of course to assemble the bearing. The tolerance designed by Xu Zhenming is an interference fit. The outer diameter of the main drive shaft is 20 wires larger than the inner diameter of the bearing.20 silk is a folk term, 0.2 mm in mechanical terms.With such a large margin, cold assembly cannot fit the bearing on the main drive shaft.

Li Dayan was very strange during this time, and he was always close to Xu Zhenming in everything.

He was on the night shift today and rested during the day, but he also came to the Honghe Township Agricultural Machinery Factory to help assemble the first lathe."Boss Xiao Xu! The bearing heating temperature has reached!" At this moment, he wiped the sweat from his forehead and shouted.

The bearing is heated by electric heating in the oil tank.After reaching a certain temperature, the bearing will undergo thermal expansion when heated, before it can be inserted into the main drive shaft.

"Li Weiguo! You can measure the inner diameter of the inner ring of the bearing, the margin must be more than 80 threads before it can be assembled!" Hearing Li Dayan's report, Xu Zhenming asked an employee to wear fire-resistant asbestos gloves to help lift the bearing.

Li Dayan is not proficient in business. After hearing Xu Zhenming's instructions, he asked in surprise, "Boss Xiao Xu, why should I exceed the 80-slice allowance?"

"The greater the clearance for the work piece assembled with interference tolerance, the better! For the work piece with transitional fit and clearance fit, just heat the work piece a little!" Xu Zhenming glanced at Li Dayan and taught him the common sense experience of assembly fitter.

Not long after, Li Dayan told Xu Zhenming that the bearing had been heated, and the balance had exceeded 90 threads.

The most stressful assembly of the main drive shaft is about to begin, and everyone is like a big enemy!Because once the bearing is lifted out of the hot oil tank, it will quickly cool down.Before the bearing cools, it must be assembled to the exact position of the main drive shaft.Otherwise, after the bearing cools down, it will be stuck on the main drive shaft, and must not be up or down.

In this way, this bearing will be scrapped.

Of course, some small factories use hydraulic tools to pull the bearings out and reassemble them.This operation method will affect the accuracy of the machine tool!

"Naruko! Hurry up! Hold the mat and I will turn the sledgehammer!" Li Quan shouted after seeing Xu Zhenming putting the bearing into the main shaft.

Xu Zhenming took the sledgehammer first and said to Li Quan: "Master, you take the mat, I will turn the sledgehammer.'The sledgehammer should shake slightly, and the small hammer should strike continuously.' I understand the truth!"

Xu Zhenming said this little secret is the secret of knocking the workpiece into place during hot assembly.

The sledgehammer is powerful, and hitting the workpiece will damage the workpiece. You must use a tooling made of copper as a cushion; the small hammer is actually made of a copper rod, which is relatively soft and can directly hit the workpiece.

After Li Quan supported the tooling mat, Xu Zhenming rounded the sledgehammer and hit the tooling continuously.His posture is very standard, every stroke hits the center of the tooling.After dozens of consecutive beatings, the bearing has been accurately positioned.

"Naruko! Who did you learn the sledgehammer technique from?" Li Quan asked in surprise when he saw this scene.Looking at Xu Zhenming, his eyes were full of approval.

"Little brother! Unexpectedly, you still have this hand!" At this time, Zhang Gui, the fat man who was debugging the CNC lathe, also raised his thumb to praise Xu Zhenming.

Experts will know if there is any when they reach out.Xu Zhenming's movements are very sophisticated, and the entire assembly process is done in one go, which is not something ordinary people can easily do.

At this time, all the fitter masters involved in the assembly looked at Xu Zhenming with different eyes.

"Master! I learned it based on the movements of you and Master. I have been secretly practicing for a long time!"

Seeing that everyone looked like this, Xu Zhenming gave the credit to Li Quan and Ma Jimin.

After listening to Li Quan, he pointed at the fat Zhang Gui and scolded, "Look at Zhang Gui! Naruko has only been apprentice with me for more than two months, and the sledgehammer wheel is no worse than me! Learning craftsmanship means you are not afraid of hardship! When can you do this?"

"Huh? Master, I'm going to debug the CNC lathe!"

Fatty Zhang Gui blushed and walked away.He is most afraid of Master Li Quan accusing him of not working hard, especially when there are too many people.

Finished the hot assembly of the most difficult interference tolerance fitting workpiece, the following work is much faster.A little more than an hour later, Xu Zhenming, Li Quan and others assembled this small car that had been dismantled.

Xu Zhenming personally debugged, and checked whether the lubricating oil of various transmission parts was in place.Then, he turned on the power and started the old 6130 minivan.

After the first workpiece was cut, he measured the accuracy of the workpiece.I couldn’t help feeling happy: “The machining accuracy of this machine has actually been improved by a notch, from 0.05 mm to 0.01 mm! This time it’s a big profit!"

Ma Jimin, who had always been worried, heard that the first lathe had been repaired, and he had already arrived at the scene."Xiao Xu, how is it?" Seeing Xu Zhenming's mouth with a smile, he asked anxiously.

"Hehe...Master! This machine has an accuracy of 0.01 mm, which is not worse than the accuracy of the ordinary cars produced in the 1980s!"

Seeing Ma Jimin was so anxious, Xu Zhenming didn't sell it off, and directly told him the answer.

"How is it possible? Quanzi, you go and test another workpiece to see!"

Ma Jimin was very surprised and arranged for his apprentice Li Quan to experiment with a few more artifacts to see.

Li Quan didn't believe that this old car can be restored to such an effect!He brought several workpieces and prepared to experiment several times.

When the first workpiece is down, the accuracy reaches 0.01 mm, which is slightly worse than the 0.005 mm accuracy level!

The second work is the same!

The third work piece...the fifth work piece is the same!

"Naruko! Good job!"

Seeing this good result, Li Quan, who has always liked no praise, couldn't help but raise his thumbs to praise his apprentice.

Ma Jimin laughed from ear to ear, and laughed and said: "Naruko! If this continues, the machine tools of the Honghe Town Agricultural Machinery Factory will be repaired again. The value of these machine tools can reach ten million yuan!"

Xu Zhenming also thinks.However, he was afraid that some people would be jealous!So he laughed and said: "Master! The machine tool that is normally repaired can maintain the accuracy of the original machine tool! I am blind to this lathe, and I will not count!"

"That's not easy! After this lathe is repainted, it will cost at least 170,000 yuan!"

"Boss Xiao Xu has good skills and good fitter skills!"

"Our factory can produce machine tools in the future! Haha!"

Seeing this, the employees present all laughed and talked.

Only now did they know that their little boss was very skilled.Whether it is mechanical design, drawing, or fitter assembly, they are much better than ordinary people!

After winning the first 6130 minivan, Xu Zhenming handed over all subsequent repairs to the machine tool to Ma Jimin, and gave the fat Zhang Gui and others a 3,000 yuan bonus for conquering the first CNC lathe on the spot.

The place where the bonus is distributed is in the light industry workshop of the Honghe Township Agricultural Machinery Factory. The bonus amount per person exceeds 300 yuan, which is much higher than the monthly salary of ordinary employees.

"Haha! Boss Xiao Xu is fetal gas!"

The employees who received the reward all smiled and murmured quietly.

The other employees who did not receive the bonus encouraged themselves: "We will definitely refurbish all the machine tools, and strive to raise the accuracy of these machine tools to the next level!"

Because Xu Zhenming announced in public: Yiming Company officially took over the first business of Honghe Town Agricultural Machinery Factory, namely machine tool renovation and transformation and CNC machine tool transformation.All employees who participate in this business will get cash rewards as long as they conquer a machine tool!

His management method comes from his rich factory management experience in his previous life: cash rewards on the spot have the best effect, and workers are the easiest to form a competitive heart!

Xu Zhenming was very happy to see the workers holding back their energy.After all, these people are the main force that can create more wealth for him.

After he arranged the work, he was going to use sawdust mixed with washing powder to clean the oil stains on his hands and face.Because he will go to the Honghe Township Government to sign the official transfer contract of the Honghe Township Agricultural Machinery Factory.

"Naruko! How did you make it like this?" At this moment, Wang Zhuoya in a court uniform walked up with a laugh.

Wang Zhuoya was here with He Lu, and the two big beauties immediately added a scene to the light factory.The young and unmarried workers immediately worked seriously and looked up at the two big beauties, He Lu and Wang Zhuoya.

He Lu is tall, and today she wore a set of white-washed denim clothes with her big long legs eye-catching.Xu Zhenming, who likes girls in jeans, couldn't help but take another look.

"Lawyer He, Sister Zhuo Ya, you two wait a moment, I wash the oil in my hands and come to join you!" After a little dazed, Xu Zhenming greeted with a smile on his face.

After all, it’s really good to be with beautiful women!

Since He Lu became the legal adviser of Yiming Company, she and Xu Zhenming often talked on the phone, and the two knew each other a lot.Neither she nor Wang Zhuoya left the factory, but accompanied Xu Zhenming who was washing his hands.

"Mr. Xu! Do you usually work like this? As a big boss, you have to work on the front line!"

She asked Xu Zhenming curiously.

Xu Zhenming knew what He Lu meant.

Nowadays, nouveau riche in the society dare not flatter the quality of the nouveau riche. I carry my big brother and hold a tea cup all day long.I don't know how much money I have, but I am scary and show off my wealth all day long.

He Xu Zhenming would not do these, nor would he bother to do it!

Thinking of this, he laughed a few times and said half-jokingly: "Lawyer He, I am actually a part-time worker! How can I be separated from the masses when working for a group of workers?"

Seeing Xu Zhenming's sourness, Wang Zhuoya rolled his eyes: "Sister, I specially asked for a leave today to help you work. You are also a part-time worker. Which boss does my sister ask for a salary?"

She loves to laugh, and she is somewhat similar to Sister Han, and she laughs herself as she speaks.
