Big Country Intelligent Manufacturing

Xu Zhenming was thinking about things in his heart, and didn't care too much about what the two old classmates thought of him.The heavy-duty workshop was preparing for the installation of machine tools. He was very worried and wanted to go back soon.

The installation of the machine tool is very important and will affect the service life and machining accuracy of the machine tool!

For example, the two original heavy-duty horizontal cars of the Honghe Township Agricultural Machinery Factory, fortunately, have not machined the heavy-duty long shafts. Otherwise, there is a possibility of a production accident of cracking of the machine bed, not to mention affecting the machining accuracy of the workpiece.

Busy people always pass by faster.Not long after, Xu Zhenming had already returned to Yiming Company.At this time, Ma Jimin is leading the workers in the day shift to inspect the poured machine tool foundation.

In fact, Xu Zhenming has checked the foundation of all machine tool installations twice.

The first time it was bricklayer Li Daoben, who used the bricklayer's standing tool level.The accuracy of the spirit level is very low, and the height of the level error of 1-2 mm can not be checked.

The second time is Xu Zhenming himself.He uses a frame spirit level.The accuracy of the frame level is much higher, but the inspection area is relatively small, and it is generally used in small plane calibration.

Xu Zhenming was not relieved, and bought an infrared level and an infrared theodolite to check the flatness of the machine tool foundation.In the early 1990s, the price of an infrared level was very high, costing several thousand yuan per set.Unlike later, any small foreman engaged in engineering has an infrared level.

Seeing Xu Zhenming coming, Ma Jimin, who had just completed the plane inspection of the machine tool foundation, came to report with a smile: "Naruko! The master tiler you hired is not bad. Of all the machine tool foundations, only two machine tool foundation planes have a slope, with an error of 1.5. About millimeters, it should have little effect! At that time, we can use the horn to'level out' it."

"Leveling" is a professional term for mechanical installation, which refers to the use of gaskets to adjust the level of the mechanical installation base.All the installation surfaces of the machine are on a horizontal surface.Whether it is a machine tool or a machine, it is operated like this.

Logically, Xu Zhenming should agree with Ma Jimin's opinion.This is how ordinary factories operate.However, he thinks that after spending such a large price to re-pouring the foundation, it should be perfect.

Moreover, machine tool gaskets and concrete are two media. Although the coefficients of thermal expansion are very close, there are some differences.Once the machine tool gasket is used, errors will occur in the plane of the machine tool in summer and winter, which will affect the machining accuracy.

Thinking of this, Xu Zhenming said euphemistically: "Master! Didn’t I make a leveling machine? That machine was made for leveling the foundation of the machine tool installation. You should arrange for the workers to install the foundation grinding of two machine tools with a slope. level!"

This flattening machine is made by Xu Zhenming imitating the wooden floor flattening machine and is specially used to flatten the foundation of the concrete machine tool.He was well prepared and used mechanical equipment to level, instead of using soil to find the level.

This point comes from his work experience in his previous life, which he learned secretly from German machine tool installation technicians.This machine tool installation concept is ten years ahead of China.It was not until the emergence of a five-axis linkage CNC machine tool in China that everyone paid so much attention to the installation of the machine tool!

Hearing this, Ma Jimin shook his head with a wry smile, still unable to understand why Xu Zhenming was so strict.

"Master! The expansion coefficient of the machine bed iron and concrete is different, which will affect the machining accuracy of the machine tool!"

Seeing Ma Jimin's appearance, Xu Zhenming told him the reason.

"That's the truth! However, these machine tools are old machine tools from the 1950s. Do you need to be so particular about it?" Ma Jimin felt that the error had nothing to do with the overall situation.

Xu Zhenming disagrees with this.If all mechanical engineers think so, the manufacturing level of our country's equipment will never be improved, and Yiming will not be able to buy high-precision domestic machine tools.

Thinking of this, Xu Zhenming still gave Ma Jimin a little bit of face, and said with a smile: "Master! Most of the machine tools in the heavy-duty workshops, I have to transform into CNC machine tools. CNC machine tools naturally require much higher installation foundation!"

Hearing this, Ma Jimin's expression suddenly became more serious.After he heard that Xu Zhenming wanted to turn waste into treasure and transform old-fashioned machine tools into high-tech CNC machine tools, he naturally paid more attention to the opinions of his students!Soon, he called a master to arrange the task of smoothing the foundation of the machine tool.

After arranging production tasks, Ma Jimin accompanied Xu Zhenming to inspect the heavy workshop again.This time, they are going to inspect the anti-seismic ditch of the machine tool foundation.

The anti-vibration ditch of the machine tool foundation has not yet become popular in general machinery factories.Until later, when high-precision five-axis machining centers entered the country, many machinery factories paid attention to this very simple facility.

Yiming's machine tool foundation anti-vibration trench was designed by Xu Zhenming.At the beginning, even Ma Jimin didn't understand.He was very curious and asked: "Naruko! Why is there a deep trench around the foundation of all machine tools without concrete?"

Xu Zhenming explained it for a long time before convincing the old man.

The function of the anti-vibration ditch is to prevent the vibration source near the factory and transmit the vibration energy directly to the machine tool, thereby affecting the accuracy of the machine tool processing workpiece.

Vibration energy is propagated on the ground in the form of waves, such as seismic waves.An anti-vibration trench is set around the foundation of the machine tool to isolate part of the vibration energy, thereby reducing the impact of the vibration energy on the machining accuracy of the machine tool.The medium in the seismic ditch can be plant ash or sand.Xu Zhenming collected materials on the spot, using yellow sand.

At that time, when he got the design drawings, the old-minded Ma Jimin was stunned by discussing with Xu Zhenming for a long time before he understood his disciple's ideas.However, he has now been convinced by his disciple's theory.

The two looked around and found that the earthquake-proof ditch was constructed in accordance with the design drawings, and their mood was much better.If everything is normal, the machine can be installed early tomorrow morning.

At this moment, the electrician Wu came to Xu Zhenming's side with a checklist for machine grounding.He frowned and said, "Boss Xiao Xu! There are a total of four machine tools whose basic grounding does not meet your requirements. The grounding resistance is more than 7 ohms and less than 10 ohms. It shouldn't be a big problem, right?"

"It's not a big problem! Our previous machine tool hasn't been grounded yet, it's not well used!"

Ma Jimin thinks it doesn't matter, and doesn't want to have any extra branches.Complete the preparations for the installation foundation early and put the machine in place early, and Yiming's production can be several days ahead of schedule!

Upon hearing this, Xu Zhenming disagreed.He looked at Ma Jimin with a smile and asked euphemistically: "Master! Did you forget that we are going to transform the machine tool into a CNC machine tool? The microcomputer control system of the CNC machine tool is most afraid of stray magnetic interference. Good grounding can shield the stray magnetic wave! "

These words come from his work experience!

He once renovated a CNC lathe, and the phenomenon of random feed often appeared. The electrical engineer who went to repair it did not find the reason.When it was Xu Zhenming's turn, the boss who bought the CNC machine tool had already issued an ultimatum: If this problem can't be solved anymore, he asked for immediate return and compensation!

Xu Zhenming was still young at the time and had little experience.When replacing the new computer version, he added an anti-interference circuit and re-grounded the CNC machine tool.The chaotic feed of this CNC machine tool is much better, but the problem still cannot be solved completely.

Later, he discovered that there was a substation near the factory, which would have strong electromagnetic effects on the work of CNC machine tools.After finding out the reason, he asked that factory owner to make a metal mesh cover to protect the CNC machine tool, and also ground the mesh cover to eliminate stray electromagnetic.In this way, he completely solved the phenomenon of random feeding of this CNC lathe.

Because of this incident, the boss deliberately gave him a tip of 500 yuan, and Xu Zhenming's boss also gave him a bonus.Through the failure case of this CNC machine tool, Xu Zhenming paid special attention to the technical parameters of machine grounding.

Thinking of this, he said with a serious expression: "Master Wu! The grounding resistance of the machine tool cannot exceed 7 ohms!"

"The foundation of the machine tool has been poured, what should I do!" Old Wu said with a bitter expression.

Seeing that his disciple and grandson attaches so much importance to grounding, Ma Jimin will definitely support him.At this time, it is impossible for him to contradict his apprentice and the boss.Besides, the bosses of private enterprises speak loudly, and they make sense both positive and negative!He raised no objections.However, he had no good solution for the moment!

"Let's do it! Install the hole opener with an electric hammer, re-drill the deep hole on the basis of the machine tool, and pre-bury the long screw as a grounding pole!"

Seeing that Wu, an electrician, had no good way to deal with the grounding of the machine tool, Xu Zhenming could only solve the matter with a local method.

If this is a German machine tool installation technician, he will definitely ask to remove the poured machine tool foundation and start over.In this regard, Xu Zhenming has experienced the rigorous taste of Germans.

Although the pouring of the machine foundation is not perfect this time, it can only be done like this!

The theoretical level and philosophy of Yiming’s technicians have not been cultivated, so they can only take it slowly!

Thinking of this, Xu Zhenming smiled slightly: "Master! I have to trouble you more. After we install the machine this time, it may take many years, so we must strictly require the workers below!"

After hearing the words, Ma Jimin felt a little embarrassed.He immediately arranged for a master and took a few young workers to embed the ground pole again.

Fortunately, in addition to these few unsatisfactory places, the entire machine tool foundation pouring project is not bad.After rectification, the machine will be officially installed in the day shift tomorrow.

Seeing that the situation was pretty good, Xu Zhenming was relieved a lot.With a smile on his face, he came to the junction between the heavy-duty factory and the light-duty factory.

Between the two rows of factory buildings, there is a wide aisle, about 1,000 square meters.Xu Zhenming is going to install a sun shed roof on the aisle and turn the aisle into a factory building.

Director Sun is leading a group of young workers welding the steel frame of the sun shed.Director Sun's name is Sun Ziliang, and is now employed by Xu Zhenming as the deputy director of the Honghe Town Agricultural Machinery Factory.He is leading a few young workers to do electric welding in the west end of the aisle, and there are also a few young workers working on the east end.

At the beginning, Xu Zhenming was in a good mood.When he saw this group of young workers at work, his expression became gloomy.

It turned out that none of these employees were wearing safety helmets, did not tie safety ropes, and were still working with cigarettes in their mouths.

In later construction sites, such scenes abound.Electric welders who weld steel structures like to work with cigarettes in their mouths. Safety helmets and safety ropes may be equipped in a way to fool the supervision of the project site.

However, Xu Zhenming did not want Yiming's employees to do the same!

He has been engaged in factory management for many years and has encountered too many accidents at work!

There are many machine tool workers who have their heads cut off by the machine while they are operating the machine tool; some assembly fitters are smoking while heating the workpiece, causing the fuel tank to catch fire, and many of them are burned...In short, they are doing work. Just concentrate and not be distracted!Otherwise it will cause an accident!

The behavior of a few young workers on the scaffolding at the east end of the aisle is a violation of Yiming's internal production safety management regulations!Thinking of this, Xu Zhenming walked to the scaffolding at the west end of the aisle and shouted: "Director Sun, you stop first! I have something to discuss with you!"

Sun Ziliang was surprised when he heard this.He put down the welding tongs in his hand and took off the protective mask.This old man is a real man, he likes to work without being lazy.He came to Xu Zhenming's side and asked in a low voice, "Boss Xiao Xu, are you looking for me?"

"Director Sun! With so many workers, you and the Director Ma must be off-production, just do a good job in production management!" Xu Zhenming smiled and said, not straightforward to embarrass Sun Tzu.

Sun Ziliang shook his head: "Why don't you work! I'm not embarrassed to take your salary!"

"Director Sun! As long as you implement the internal management regulations that I have formulated, the value created by directly participating in labor is even higher than the value created by directly participating in labor! Look, they are not wearing helmets, working at heights without wearing safety belts, and they are working. I smoke while I live. I can’t afford to pay if someone else falls! If a worker becomes disabled, he will suffer for the rest of his life!"

Xu Zhenming's tone was very gentle, not heavy, but very reasonable.

After Sun Ziliang heard this, his face flushed.He immediately called all the current employees to punish the young employees in public in accordance with factory regulations.

"Why is it fine? I didn't come down to smoke because I was trying to get ahead!"

"This scaffolding is not high, it is not a high-altitude operation, you don't need to wear a seat belt!"

"I put a safety helmet on the scaffolding. Wearing a safety helmet affects work efficiency! I am for the good of the company, so why should I be fined?"

After hearing the fines, the group of young workers quit, and they all yelled.

They are all quibbling, each telling their own reasons.The main purpose is to be unwilling to accept punishment for fear of losing economic benefits!

Seeing this situation, his grandson was so angry that he was ready to swear.

This year, the consciousness of the masters of the employees is still quite high. They have not experienced the baptism of the big industrial era, and the edges and corners have not been smoothed; nor have they experienced the influence of the big entrepreneurial era, and they will go home to start their own businesses.

Therefore, these people are not easy to manage!

Thinking of this, Xu Zhenming comforted Sun Ziliang next to him, and then said with a serious expression: "You should take a closer look at the labor contract! There is an article on it: Yiming has the right to expel employees who have repeatedly violated factory discipline!"

Seeing that my boss came out to speak, the voices of these employees who violated factory regulations were much lower.They all know the labor contract during the probation period.However, they believed that they were once full-time employees, and Yiming did not dare to expel themselves.When Xu Zhenming said this, they were a little flustered.

"Mr. Xu! We work overtime and don't be lazy. It's for the good of the company, and we don't deliberately violate the factory rules!"

They were still whispering sophistry.

"Wrong! You are not earning money for me, but for your own money! According to the regulations, the company will not lose a penny of your overproduction reward! You will also be punished in accordance with the regulations! All fines will be used for For employee benefits, the company will not withhold a penny! It is clearly written in the "Employee Handbook", please go back and take a look!"

Xu Zhenming broke their delusion and told these people to abide by the factory rules.Otherwise, either be punished or expelled!

At present, Yiming's salary level has exceeded that of nearby textile companies.This makes the workers who come to work in the factory reluctant to leave!

Thinking of this, these young workers who violated labor discipline all bowed their heads blushing!It seems that they have regretted it!

"Are you willing to accept punishment? Are you willing to accept the leadership of Director Sun?"

Seeing this situation, Xu Zhenming raised his voice and asked them.

"Yes! Others don't know, I am willing anyway!"

These people were whispering.

Xu Zhenming didn't get rid of the blisters and helped Sun Ziliang make a punishment decision.This will damage Sun Ziliang's prestige!He said hello to Sun Ziliang and left and walked towards the staff dormitory.
