This hydraulic system does not respond sensitively. It must be an oil leak in the hydraulic system, which has nothing to do with the electronic control system!
Thinking of this, Xu Zhenming asked Sun Chao to change the hydraulic system to manual adjustment, and asked Wang Qiang, Zhang Gui and others to wipe off the oil on the hydraulic lines.
In this way, if there is an oil leak, everyone will be able to see clearly the first time.
"Papa! Papa..." Following Sun Chao's movements, the hydraulic cylinder began to work. It stretched out for a while and retracted again.I didn't operate it a few times either, and a lot of light yellow hydraulic oil had leaked out of the cylinder body.
By now, there is no need for Xu Zhenming to speak, everyone already knows what went wrong!
"Does domestic famous brand hydraulic cylinders have this kind of glitch?"
"Damn! This glitch has wasted many hours of me!"
"Why does the hydraulic cylinder leak oil?"
The young technicians were very angry at this time, whispering quietly.
They don’t understand why the brand-name products they just bought might leak oil?
Although Xu Zhenming is an old machine, he is not an expert in hydraulic systems.
Hydraulics is a more exquisite professional, which requires experience and theoretical accumulation.However, through his many years of experience, he initially judged that the seal of the hydraulic cylinder should be faulty.
Thinking of this, he told Sun Chao: "Sun Gong! First release the pressure in the hydraulic system, and then prepare to open the hydraulic cylinder to see. It should be a problem with the seal of the hydraulic cylinder."
Xu Zhenming made a lot of sense.When overhauling high-pressure pipelines, be sure to release the pressure in the pipelines first, otherwise accidents may occur.He once heard a story:
In one factory, the workers in charge of overhauling high-pressure pipelines did not pay attention and did not release the pressure in the pipeline.When removing a pipe plug, the plug flew out like a bullet, piercing the steel plate three meters away.
"Mr. Xu! Do we want to replace a hydraulic cylinder?" At this time, Sun Chao, who was in charge of the overhaul, asked Xu Zhenming.
Although he knew that there was a problem with the cylinder, he did not believe Xu Zhenming's judgment: How could there be problems with the newly purchased hydraulic cylinder and the newly installed seals?
Other workers are not as experienced as Sun Chao, and some have not seen the process of repairing hydraulic cylinders.All of them are dubious, working with Sun Chao and others.
At this time, Xu Zhenming shouted to Ma Jimin who was walking: "Director Ma! The seal of this hydraulic cylinder is broken, please reinstall one!"
He knew that the details of the employees in his factory, such as the maintenance of hydraulic cylinders, were still entrusted to the old fitter Ma Jimin.
"okay!"
Hearing this, Ma Jimin put on labor protection gloves and began to work.
Soon, this high-precision hydraulic cylinder was disassembled, and the seals inside looked normal, and there was no major problem.
Everyone was wondering when they saw this scene.
"It's a domestic seal! There is a problem with elasticity!" At this time, Ma Jimin frowned.He removed the seal of the hydraulic cylinder and handed it to Liu Yangde, who was standing by.
Liu Yangde’s task is very important. He will take the seals of this hydraulic cylinder as a sample and go to the electromechanical market in Suning City to purchase imported hydraulic cylinder seals.
"Yes! The dimensional accuracy of the cylinder seal is no problem. It should be because the raw material does not meet the requirements!"
After seeing this situation, Xu Zhenming sighed involuntarily.
There is no way. The development of domestic materials cannot keep up, and the defective rate is relatively high. Naturally, the quality of the cylinder seals is not guaranteed.
Many years later, there are companies producing hydraulic cylinders in almost every city.However, the seals of their hydraulic cylinders are all imported.Therefore, these companies also express to their customers: We use imported seals!
This is the frustrating thing, bragging is useless!
After stabilizing his mood a bit, Xu Zhenming put aside his work on the hydraulic system and ordered the workers to start the renovation and installation of the lubrication system, circuit system, tool system, hoisting system, etc. according to the renovation schedule.
The other systems are fine, even the lubrication system is a bit troublesome.Because, the lubrication pipelines arranged on the heavy-duty CNC large sleeper are all thin copper pipes, and copper welding is required.
Welding of copper parts is also a technical activity, and there are several methods such as gas welding, electric welding, argon arc welding and carbon arc welding.Without certain welding experience, ordinary welders cannot do such delicate work.Fortunately, Yiming has many experienced riveting welders, and this kind of work can be done with older gas welding processes.
In order to keep up with the progress, Xu Zhenming expanded the scope of receiving awards for technical research, so that all old workers who joined later have the opportunity to receive awards.As a result, everyone's enthusiasm was even greater, and they spontaneously arranged three shifts to rotate, striving to take down the transformation of this heavy-duty CNC sleeping car within two days.
Sun Chao, Wang Qiang and others were unwilling to go home, so they went to the office on the third floor of the office building when they were tired, and rested for a few hours.
Their office was officially moved from the machine repair workshop of the Nan'an Towel Factory to the office building of Yiming Company.Office conditions are pretty good, with air conditioning, chairs, and a computer terminal for each person.
For a few days, Xu Zhenming also had no day or night. Sometimes he went to the machine repair shop for inspections. Most of the time he spent time in Yiming's heavy-duty factory building and accompanied the workers to work overtime to catch up.
One day later, Liu Yangde bought the imported seals for the hydraulic cylinder, and Ma Jimin repaired the hydraulic cylinder by himself.Sun Chao and others worked together to restore the hydraulic system to its original state.
"Sun Gong! First operate manually, and then use electronic control!" Seeing this, Xu Zhenming yawned and commanded.
Sun Chao and others had red eyes, but their expressions were extremely excited.With their operations, the hydraulic cylinders moved very sensitively, no matter how they tried, no problems were found.
At this time, these people believed in Xu Zhenming's judgment.
"Ha ha…"
Looking at the expressions of these people, Ma Jimin yawned and laughed.
He is an experienced veteran mechanic. When he took out the hydraulic cylinder seal, he already knew the result today.
In the afternoon of the second day, this heavy-duty CNC sleeping car has been transformed.All the employees who participated in this project were very happy.They are both nervous and excited, with rich expressions.
The appearance of this heavy-duty CNC sleeping car has become taller than before.
The shell of the main body of the machine tool is still green machine enamel, equipped with a retractable protective cover.When the machine tool is working, the protective cover will automatically cover the workpiece inside.
The main console of the CNC lathe is blue and white which Xu Zhenming prefers!
The man-machine interface is a 15-inch LCD screen, and the keyboard is a 32-key touch button keyboard.This console can be retractable: when not in use, it can be stowed and placed in the electric control cabinet, and when it is used, it can be pulled out like a small computer embedded in the electric control cabinet.This main control console alone is more than ten years more advanced than similar products at home and abroad!
"Wow! This is similar to the equipment seen in the mold country science fiction film, very advanced!"
"The products we make by Yiming are definitely better than those of the Chinese people!"
The workers at the scene were all talking in whispers.
They all have red eyes and are quite excited.In fact, they still don't know the accuracy parameters of this heavy-duty CNC sleeping car, but they were shocked by the hard-line design.
Xu Zhenming knows the foundation of his own heavy-duty sleeper: no matter how it is modified, the accuracy of this heavy-duty CNC sleeper is only 0.01 mm at the highest!
However, after this CNC transformation, this machine can easily process heavy and long shafts of various shapes.Whether it is a long shaft with a tapered surface or a long shaft with a circular arc surface, this machine tool can be easily handled, and no experienced old lathe technician is required to operate the machine tool.
"Mr. Xu! You can start the trial run!"
While Xu Zhenming was in a daze, Sun Chao, who was in charge of the general commissioning, came to report on the work.
Hearing this, Xu Zhenming glanced at the heavy-duty CNC sleeping car with the protective cover closed, and ordered loudly, "Start!"
After hearing this command, the fat man Zhang Gui hit the run key of the machining program.
"Buzz..." There was a roar, and the first heavy-duty CNC sleeping car with independent intellectual property rights began to work.
On the fixture, a 350 mm thick carbon wafer bar is installed.
This bar is fifteen meters long and weighs more than ten tons. It is a blank that Liu Yangde specially bought for testing.This blank used for the test is worth more than 40,000 yuan!
Xu Zhenming is willing to spend money to develop new products.
Of course, once this heavy-duty CNC large sleeping car is successfully debugged, the shift fee for the refined car is also very amazing.Without 3,000 yuan for a shift fee, you shouldn’t want Yiming to turn on the power of this heavy-duty CNC sleeping car for you.
"Squeak..." With the automatic feed of the turning tool, a burst of noise came from the machine guard.Through the plexiglass window, everyone can see how the machine cuts the workpiece.
"Yay!"
Seeing this scene, all the young workers involved in this research task clapped excitedly.
Ma Jimin, Sun Ziliang, Liu Yangde, Sister Han and Li Quan who had just arrived after hearing the news, all grinned excitedly at this time.
The current market price of this heavy-duty CNC large sleeper produced by Yiming Company is about three million yuan, and it can only be bought with foreign exchange.
This shows how amazing the value Xu Zhenming and others have created these days!
"Mr. Xu! Is our company celebrating the successful development of such an important equipment?" At this time, Li Lan and Wu Yan, who came to take pictures of the machine tool, both approached Xu Zhenming and jokingly asked.
The two of them are going to take photos of Yiming's equipment, factories, and office locations, and then make colorful promotional materials.Li Lan can use promotional materials to run loans, and Wu Yan can use promotional materials to run business.
Seeing the two beauties of Yiming's company leaning near Xu Zhenming's side, the fat man Zhang Gui who smirked not far away was very depressed, and his smile froze.He knew that his little brother had no feeling for these two big beauties, and said in his heart: "Little brother, if you don't feel it, you can give me a beautiful woman!"
"Minister Wu and Minister Li's proposal is very good! I am going to invite everyone to dinner tonight!" At this time, Xu Zhenming was talking with a smile on his face.
"Where? Hongsheng Fisherman House?"
Everyone asked him with a smile.
"Yiming's small restaurant is just about to open. I invite everyone to taste the cooking skills of the cafeteria chefs!"
Seeing everyone's hopeful eyes, Xu Zhenming gave an unexpected answer.
"what?"
Everyone shook their heads pretending to be disappointed.
Everyone has tasted the craftsmanship of several masters in Yiming's cafeteria, and they are indeed not bad.
A few days ago, the Yiming canteen opened for business. Xu Zhenming has arranged for all the employees of the factory to have a dinner together. Only then did everyone know that the craftsmanship of the cafeteria chefs is no worse than that of the chefs in the restaurant!
Today, the little boss Xu Zhenming, because of the proposal of the two big beauties of the company, is going to invite everyone to dinner again.The workers present were actually very happy.They all made such expressions deliberately, they were just spitting out their little boss!
Xu Zhenming adheres to the principle of saving if you can save, and spend a small amount of money to do big things. Please have a good time for the employees who have been fighting on the front line for several days.
Half an hour later, this heavy-duty CNC large sleeping car completed the processing instructions.
Li Quan, Zhang Gui, and Sun Chao all took turns to measure the chip surface of the first cut.They concluded that the accuracy of this heavy-duty CNC sleeping car has not changed, and the accuracy of the machine tool is still 0.01 mm.
"Okay! Let's all go to the cafeteria and drink celebration wine!"
After seeing this, all the employees left with a smile.
First, they are to applaud the bonus they are going to get; second, they are proud to build the most advanced heavy equipment.
When Sister Han led everyone away, Li Quan, Ma Jimin, Sun Ziliang and Liu Yangde did not leave.They all gathered around Xu Zhenming and asked with a smile, "When will our company move and when will it open?"
"In three days, I will start to transfer Suning High Gear's business to production! I am going to hold the opening ceremony of Yiming Company on December 1. At that time, the relevant leaders of Honghe Township will definitely come to participate in the opening ceremony. Plan!"
Xu Zhenming and several masters who cared about him walked toward the staff canteen while telling his plan.
What he said is true.
Since he accepted the Honghe Township Agricultural Machinery Factory, he has paid a lot of national and land taxes.The leaders of Honghe Township Taxation Office attached great importance to Yiming Company and came to Yiming Company to guide the work in two days.Chief Jiang Xiang, who is in charge of industry, often invites relevant superiors to inspect the company.
Although these entertainment tasks were handled by Sister Han alone, Xu Zhenming as the boss still knows the reason for everything!
After listening to Xu Zhenming's explanation, Li Quan and others nodded with different expressions.
They all know Xu Zhenming's difficulties, and they can only help in the specific production business!
This hydraulic system does not respond sensitively. It must be an oil leak in the hydraulic system, which has nothing to do with the electronic control system!
Thinking of this, Xu Zhenming asked Sun Chao to change the hydraulic system to manual adjustment, and asked Wang Qiang, Zhang Gui and others to wipe off the oil on the hydraulic lines.
