Chapter 283 Xinghai Group Has Another World Number One

Chapter 283 Xinghai Group has another world number one

"Equipment works fine!"

"Okay, start loading!"

Following the order of the production supervisor, in the No. 1 production area of ​​Xinghai Group's aluminum alloy production workshop, workers operated the handling equipment according to the operation requirements on the display screen, and put a certain number of standard aluminum ingots into the material box.

Aluminum ingots are automatically screened and dropped into the conveyor belt.

When the aluminum ingot passes through the scanning area of ​​the visual handling robot, the conveyor belt will stop, the camera will shoot, and the image will be analyzed. The robot will automatically grab the aluminum ingot and put it on another conveyor belt. At the same time, the program will automatically record the number of grabs.

When the program determines that the quantity meets the process requirements, it will execute the next step - weighing!

Because the weight of each aluminum ingot is still somewhat different, automatic weighing and recording data will generally be within a certain error.

Similarly, aluminum ingots of different weights will automatically grab other elements.

After other elements meet the conditions, aluminum ingots and other elements will be automatically put into the melting furnace, step by step according to the program.

This automatic program, including heat treatment temperature and time, heating rate and cooling rate, has strict requirements.

The aluminum alloy factory of Xinghai Group only needs workers to carry the aluminum ingots, and the rest is handed over to the equipment.

A maximum of 20 tons can be smelted in one furnace. Just input the value for how many tons of aluminum alloy needs to be smelted.

Only when the conditions are met will the next step be executed.

For example, if the quantity of a certain element is not enough, it will have a voice prompt:

"Magnesium is underweight, 5 kg short!"

At the same time, there is a road map of the total operation on the big screen, where the operation will be displayed in green, and if there is an abnormality, a red dot will appear at a certain point, and the engineer will know immediately which link has a problem.

Advanced evolution has reached this level!

Aluminum alloy factories at home and abroad do not have such advanced automated production lines!

It looks like a black technology and has reached intelligence.

In fact, it is not black technology. Experts in automation design know that it is still possible to do this, but it requires a deep understanding of automation knowledge and experience, proficiency in use, and supporting equipment. money.

For example, visual automatic grabbing robots are very common in automated production companies.

A robot + vision system + auxiliary equipment that can grab 50KG can be realized for hundreds of thousands of yuan.

A production line will have several vision automatic grabbing robots and other types of robots, while the general factory directly uses manual handling.

The robot will not grab more workpieces. Every time it grabs an aluminum ingot (suction cup), it is equivalent to executing a grabbing and handling procedure. How many times the handling procedure is executed is equivalent to how many aluminum ingots it grabs.

Another example is the blanking automatic screening equipment for aluminum ingots, which is actually a set of tooling that is widely used in factories by using the gravity of the workpiece.

Of course, in order to realize the automation of Xinghai Group's aluminum alloy smelting, a lot of automation equipment is needed, and these automation equipment are connected in series.

Maybe if you have money, you can buy these automation equipment.

However, the most difficult part of the Xinghai Group's automation equipment is the overall logic design and the logic program of the specific process.

This is the core of automation equipment!

An abnormality occurs in one link, and all other links are finished.

There are engineers on site watching, that is, when abnormalities occur, they will be dealt with in time.

The most important thing is production safety. When the robot is running, it will not automatically stop due to a worker's safety accident.

It is not difficult to achieve this step. It is to add safety gratings. When a safety grating is encountered, a certain robot or production line will stop running. After leaving, it will automatically run again. However, it is impossible to install safety gratings everywhere. Production brings trouble. If it is not necessary, try not to install it.

In addition, it is human-computer interaction, which is currently the most difficult to solve. The production line of Xinghai Group only has a little taste.

Although the workers have been trained, they don't know how to maintain the equipment, and engineers need to be responsible.

A few hours later, the first furnace of aluminum alloy 6009 for automobiles was produced.

The specifications of aluminum alloy sheets for automobiles are based on the industry standards issued by the industry and information departments, and Xinghai Group makes adjustments according to the conditions of various automobile OEMs.

For example, 6009 boards are supplied with a thickness of 2mm, the mainstream widths are 1000mm, 1500mm, and 1800mm, and the mainstream lengths are 4000mm and 5500mm.

The first furnace of aluminum alloy plate 6009 in front of us is 1500mm wide and 5.5m long.

After the aluminum alloy plate is cooled, the engineer asks to pick up the vernier caliper to measure the thickness error of the plate.

The allowable tolerances for different plate thicknesses are different. According to industry standards, for a plate thickness of 2mm, the allowable tolerance is ±0.13mm, which is about 6.5% of the plus or minus plate thickness.

However, Xinghai Group requires a tolerance of ±0.10mm, that is, plus or minus 10 wires, which must be controlled within 5% of the plus or minus plate thickness.

5%, in fact, is the supply standard for the plate thickness standard of many materials.

For example, if the plate thickness is 20 mm, the thinnest part should not be lower than 19 mm! If the plate is severely corroded and thin, it can only be downgraded.

Generally speaking, steel mills and aluminum mills can meet this industry standard, but if the control is not good, it will be too thin or too thick.

Although the purchase price is calculated according to the weight, the plate thickness error, especially for the sheet metal bending process, has a great impact.

For example, this furnace of 6009 aluminum alloy plate of Xinghai Group can be numbered XXXXX20110421001 furnace number (hereinafter referred to as furnace No. 1), and the thickness of the plate is very uniform, if it is 2.02 mm.

The 6009 aluminum alloy plate in the next furnace will be a different furnace number, and the plate thickness may be 1.98mm.

Although both 2.02mm and 1.98mm are in line with the tolerance, they will bring troubles to sheet metal bending production.

Different plate thicknesses have different bending force requirements, and the angle of the final folded sheet metal shape will definitely have deviations!

This makes it difficult to bend!

Moreover, even if the plate thickness is the same, the hardness difference is too large, and the bending strength is also different!

It's over, Barbie Q is over!

Therefore, if you want to achieve mass production, the difficulty is here!

Not stable!

Those who are engaged in sheet metal bending are most afraid of encountering materials with different furnace numbers and batch numbers. The thickness of the plate is different, and the hardness of the material is also different. It is annoying to always adjust the process parameters.

Sheet metal engineers, the most annoying thing is to encounter this situation.

A factory engaged in sheet metal production will definitely require a stable plate thickness.

In particular, automobile OEMs have a high degree of automation and require stable sheet metal, otherwise it will be difficult to achieve automated production.

At this point, the quality engineer has already measured the measurement quantity.

"Every 200mm, I measured 12 points, all 2.01mm! Great!"

The minimum reading of the vernier caliper is 0.01 mm (50 scales on the sub-reading scale, 0.5mm/50=0.01mm)

If you want to measure more accurately, you need other more accurate thickness measuring instruments, but it is not necessary.

"The roughness is qualified! It's very bright, within 0.4."

Quality engineers judge with the naked eye, and can judge through reflective surfaces and hands. It is very troublesome to use instruments to measure.

In addition, it is necessary to measure the levelness, that is, the error of unevenness within a few meters.

After the measurement, measure the hardness again.

Because the aluminum alloy 6009 is relatively soft, a portable Vickers measuring instrument was used to measure the hardness.

After about half an hour, the measurement of main indicators such as thickness, roughness, levelness, and hardness was completed, and the quality engineer completed the measurement.

After measuring the furnace number, the thickness of the 6009 plate in the No. 2 production area was also cooled.

The quality engineer then conducts measurements, and the difference between different furnace numbers mainly depends on the difference in thick plates.

Furnace No. 2, thickness 2.02 mm!

very good!

The quality engineer is most afraid that the No. 1 furnace is 2.10 mm, and the No. 2 furnace is 1.90 mm. Although they are all within the tolerance range and meet the requirements for thick plates, the actual tolerance has reached 0.2 mm. This tolerance is very large!

The plate thickness of different furnace numbers is unstable, and the sheet metal engineers of the automobile factory will be scolded.

"I quit!"

"It is necessary to purchase aluminum alloy plates with stable thickness, otherwise mass production will not be possible, and the adjustment process will be deadly!"

Generally speaking, from the perspective of material size and hardness measurement, the two furnaces of aluminum alloy plates produced by Xinghai Group are excellent.

Domestic aluminum alloy factories are incomparable, but if compared internationally, it must be the top aluminum alloy plate.

The next job is not the quality engineer's job.

The R&D engineer asked the workers to cut and sample the sample, and then took it to the machining factory to process the sample for mechanical performance testing.

After cutting at four o'clock in the afternoon, the driver took the goods to the machining workshop of the headquarters base for processing samples.

At eleven o'clock the next morning, the mechanical performance results came out.

For each heat plate, three samples are taken for each tensile and impact test. Since the plate is thin and the bending is positive bending, 4 samples are required.

In Furnace No. 1, three samples were stretched. The yield strengths were 255.66MPa, 251.23MPa, and 258.42MPa, and the tensile strengths were 315.63MPa, 311.43MPa, and 318.55MPa.

The data of No. 2 furnace is not much different from that of No. 1 furnace, and it is relatively stable.

This strength is about 10% better than imported ones.

For automobile factories, perhaps this is not important, mainly plasticity, that is, elongation.

Because it is necessary to consider the cold deformation to manufacture the door of complex structure.

These 6 tensile samples of Xinghai Group were measured.

The elongation rate is between 25% and 28%!

A minimum of 20% is required to meet the requirements.

In engineering, materials with elongation δ≥5% are often called plastic materials, such as low-carbon steel, aluminum, copper, etc. under static load at room temperature;

The materials with elongation δ≤5% are called brittle materials, such as cast iron, glass, ceramics, etc. under normal temperature and static load.

In fact, if you want to cold-deform a door with a complex structure, if the elongation is lower than 15%, if the deformation is relatively large, cracks will easily appear.

Elongation and strength are contradictory. The higher the strength of the metal material, the lower the elongation. This is the law of all metal materials, and Mu Yang cannot change it.

At four o'clock in the afternoon on April 21, Mu Yang received the experimental data report from the aluminum alloy factory.

It worked!

The material is superior.

Moreover, the production is very stable and mass production has been achieved.

In this way, Xinghai Group has another world first: aluminum alloy automotive panels!

In two days, the executives of Zheli Automobile in the same city will come to inspect.

Mu Yang attached great importance to this inspection, and he wanted to accompany him personally. If the mass production did not go well, he would be embarrassed.

Zheli Group is headquartered in H City, and has established automobile and powertrain manufacturing bases in Ningcheng, Xiangtan, Rongcheng, Baoji, Jinzhong and other places in Jiangnan Province.

Shangqi Volkswagen, Yiqi Volkswagen, and Shangqi General Motors (gas=steam) are still firmly in the top three in domestic automobile production, and Zheli Automobile is in the top ten. By 2018, it has climbed to fourth place.

The Volkswagen brand has always been in a dominant position in the field of cars, and cars such as Lavida, Jetta, Sagitar, Bora, and Passat have long been among the top 20 in the sales rankings.

North-South Volkswagen has sold more than 4 million vehicles, accounting for 18% of the passenger car market in Huaguo. It is equivalent to the sum of the five Japanese brand car companies of Dongfeng Nissan, Honda and Toyota, two joint venture car companies.

Shangqi Volkswagen, you can tell it is a joint venture just by hearing the name, that is, domestic Shangqi + foreign brand Volkswagen, in addition, such as Dongfeng Nissan, BJ Hyundai, Guangqi Honda, Yiqi Toyota, Dongfeng Honda, Guangqi Toyota, Guangdong City Toyota et al.

The internal financial relationship in the auto industry is relatively complicated. Groups such as Yiqi and Dongfeng have many production bases across the country. Of course, the interpersonal relationships of these large state-owned enterprises are also complicated.

Zheli Automobile was founded by Li Shufu from scratch, and the internal interpersonal relationship is not as complicated as that of a state-owned enterprise. This is Muyang's breakthrough into the automotive aluminum alloy plate industry.

There are several models of Zheli Automobile that are very popular, such as Emgrand.

A few years later, sales of leading models such as Vision, King Kong, Emgrand GL, Borui, Boyue, Emgrand GS, and Vision SUV are all good.

With a down payment of about 40,000, you can take a new car home. For most young people with limited funds, it is easier to accept.

It is these relatively cheap but good-looking cars that make rural cars more and more popular.

April 23, ten o'clock in the morning.

Li Shufu, chairman of Zheli Automobile, and his team visited Xinghai Group's aluminum alloy factory, and were received by Mu Yang and Zhang Xiaofeng in person.

Zheli Automobile has been listed. According to its annual report last year, the revenue was 20.099 billion yuan and the pre-tax profit was 1.9 billion yuan.

Xinghai Group’s revenue last year was several billion yuan lower than that of Zheli Automobile, but its pre-tax profit was more than four times that of Zheli Group.

This year, Li Shufu is 47 years old, and his personal wealth and social influence are indeed not as good as Mu Yang, who is now on fire.

But he is the richest man in the domestic auto industry, and of course he has great influence.

The chubby Li Shufu saw Mu Yang, his eyes lit up, and he went up to shake hands with Mu Yang and said happily, "Mr. Mu, you are really a young man."

The two senior executives who came with Li Shufu were indeed surprised when they saw Mu Yang: This young man is really handsome!

Li Shufu has a son who is 26 years old this year and has long hair. The second generation of Che is really incomparable with Mu Yang before him. This is the current impression of the executives of Zheli Automobile. With Mu Yang in front of him as a comparison, there is no way to compare.

"Mr. Li, I have admired your name for a long time." Mu Yang politely shook hands with all the visitors from Zheli Automobile.

After exchanging pleasantries between the two parties, Li Shufu said enviously, "Mr. Mu, when will your company's Xinghai Building move in? Go and have a look at it then."

The 518-meter Xinghai Building of Xinghai Group has already been reported in the news, especially in City H, it has been reported on local TV stations many times, and some citizens even went to watch it.

"Hurry up, it will be the end of next year, and Mr. Li is welcome to drink tea at any time." Mu Yang said with a smile, "Your Emgrand is really popular. In my hometown town, there are many cars like this on the street."

Mu Yang didn't praise him either. In his hometown, there are indeed a lot of Emgrand cars.

"Haha, to put it nicely, the sales are very good, but to put it bluntly, we can only hang out in the countryside. We still have a long way to go, unlike your Xinghai Group, which has many world-leading technologies and products that occupy a leading position in the market. , As for your second-warranty welding machine, we are using it, I heard that it is not easy to buy, and the money made by a welding machine is more than we can sell a car."

The two exchanged business ideas, chatting while walking.

"Mr. Mu, you gave out year-end bonuses during the Chinese New Year, but did it hurt us so much?"

"No, that's such an exaggeration."

Li Shufu put on a wry smile: "Our employees, let's talk about the Xinghai Group next door, how do they give out year-end bonuses, ordinary employees have year-end bonuses for five or six months, and those engineers all give out hundreds of thousands to millions of year-end bonuses .I heard employees discussing this, and I can’t tell you how hard it is.”

Mu Yang said modestly: "If Zheli Automobile is poor, then no car manufacturer is rich. Last year, you bought 100% of Volvo's shares at a price of 1.8 billion US dollars, which shocked me."

Mu Yang brought Zheli Automobile and other high-level executives to the factory office, and sat on both sides of the long round table facing each other.

Zhang Xiaofeng opened the PPT and briefly introduced the history and honor of Xinghai Group.

Xinghai Group has many world firsts, such as handheld laser welding equipment, fiber laser, secondary welding machine, argon tungsten arc welding, titanium alloy, etc. Now, there is another world first, aluminum alloy automotive plates.

The specific parameters of aluminum alloy 6009 and 6010 are listed on the screen. Before Li Shufu came, he had already read Xinghai Group's aluminum alloy promotional materials.

When they saw it for the first time, they couldn't believe it.

There is no aluminum factory in China that can produce excellent aluminum alloy automotive plates, which are basically imported and expensive.

Zheli Automobile did not plan to use aluminum alloy in low-end cars, but they acquired Volvo, and mid-to-high-end brands used aluminum alloy automotive plates, all of which were imported.

If Xinghai Group can really produce excellent aluminum alloy automotive panels with stable quality and cheaper prices than imported ones, they will certainly be willing to purchase them.

If you can get a discount of 4,000 yuan per ton, then you can save about 200 yuan per car. The production of mid-to-high-end cars of Zheli Automobile is estimated to be about 100,000 vehicles this year. Over the course of a year, you can save 20 million yuan. not a problem.

Their pre-tax profit last year was only 1.9 billion yuan, an increase of 20 million yuan per year

At the same time, the local supply is very convenient, and the production capacity will not be affected by the shortage of raw materials. The benefits of output are difficult to estimate, but they are definitely not low.

Therefore, they decided to inspect Xinghai Group's aluminum alloy factory.

Now, it depends on the actual production capacity of Xinghai Group's aluminum alloy automotive panels and whether the quality is stable. After a while, they will go to the aluminum alloy workshop to see the actual situation, but they can't just rely on what the other party says. After they buy the goods, they will definitely have to inspect the goods.

If there is no problem, it depends on the price. This is what Li Shufu is more concerned about.

In recent months, the price of 6009 aluminum alloy sheets imported by Zheli Automobile is about 35,500 yuan/ton, and the price of 6010 is about 38,000 yuan/ton.

I also don't know what the specific pricing of Xinghai Group is.

It’s still an update, hey, I was in a bad mood yesterday and was affected
