Super manufacturing empire

"After children go to school, they must also go home at night and live in school. For them, it is not a good thing!" Children who have not cultivated independence since childhood, as soon as they enter the city, let them live in school. Not a good thing.

The current school is not very strict in the management of this aspect. Once these children become prematurely in love or something, then there will be a problem, and there will be no place to cry.

Especially, two of the three children in the family are girls, or pretty little girls...

"Then you have to live with us. Now I can't control them more and more..." Yun Su said quietly. It is fine for his daughter, but for Hu Zhen and Hu Bao, she The aunt shouldn’t be too strict, otherwise she would not be able to tell the two bear children to run away from home.

"Wait for a few days before talking. In the past two days, I will find someone to find a way to get the school done for them. I will talk about it when the time comes. When the equipment in my factory arrives, I don’t think there will be much time to come back then! You guys, if No matter how naughty and disobedient, I will send you back!" Yun Kai threatened several bear children.

These bear children are about to enter a rebellious period, and they cannot be suppressed forcefully.

Yun Kai originally planned to take them out for dinner, but Yun Su stopped him. No matter how few people were to eat outside, he would have to spend more than 100. At home, buying some meat and some vegetables was only 30 or 40 yuan.

When several children were in full growth, it was rare to see meat for a month in their hometown before. Here, with the uncle, I don’t worry about having the same kind of hard life.

When Yun Kai was there, the bear kids didn’t dare to make trouble anymore. Before leaving, they threatened to send them back to whoever was disobedient. Yun Kai rode his second-hand master bicycle towards him. The leased plant in the Zhongda Mould Industrial Park rushed.

This afternoon and evening, not only had to consider the layout of the plant, but also had to design the tooling in the evening, buy the materials tomorrow, and find some outsourcing factories to start processing.

time is tight.

These things must be done before the equipment comes back, and at the same time you have to go back to the hometown to bring the gold from home and sell it.

Otherwise, the money in his hands will not be able to purchase equipment at all.

It takes a long time for the imported equipment to be in place, and now he has not even asked the price. It is impossible to buy these imported equipment from the beginning.

The value of the gold is more than enough to pay for the price of domestic equipment.

As for business, Yiyunkai has been in this industry for so many years, will it be short of business?It would be better if the Longguang factory collapsed. They took over all of their business by themselves, and there would be no sense of guilt.

If Long Guang still belonged to Wu Feng and took away his business, it would be impossible to say that there was no guilt.

"Why did you come back so early today?" When Yun Kai returned to his nest, Hu Xiaolong's product seemed to have just woke up and was carrying a box of instant noodles.

"Come back to draw pictures! Go to the whole beer to get some wine and food. Tonight I have to stay up late to work..." Yun Kai threw Hu Xiaolong two hundred yuan and entered his house.

Hu Xiaolong was stunned, shook his head, got up and went downstairs again.

The tooling design of the car benchmark is relatively simple. Just make the parts have more stress points to avoid too few stress points so that the entire workpiece will concentrate all the weight and the generated torque to one point during the rotation processing process, which will cause the parts to suffer damage.

Yunkai has designed a lot of the same type of tooling before, so there is no need to calculate various parameters at all, just change the original four support points in a row to four rows of sixteen support points evenly distributed on the circumference .

When clamping, use a rubber pad with a large friction coefficient, which makes flexible contact between the tooling and the workpiece, avoiding the fact that there is too much force on a certain point and there is no adhesive just relying on high temperature and high pressure The thin-walled pure tungsten parts sintered together are shattered from excessive force during the cutting process.

The only thing to note is that the sixteen support columns must be linked.

However, for Yunkai, this is not a difficult task at all. A tapered steel sleeve is used in the middle of the tooling base, and a screw is used to connect the large section of the steel sleeve. In this way, the screw can be clamped. When tightening, the support column supported on the inner wall of the workpiece can be lifted up at the same time.

Of course, this adjustable range is only the final fine-tuning, the purpose is to make the sixteen support columns apply force to the part at the same time to ensure the uniformity of the force.

It was this kind of thing that caused Yun Kai to get it from after three o'clock in the afternoon until 12 o'clock in the evening, and he even hung up Huang Kui's call.

After serving as a three-dimensional model, they made a bowl of instant noodles with Hu Xiaolong, and then drank wine with the braised chicken feet and peanuts that Hu Xiaolong bought for a while, and continued to fight.

It is slightly simpler than this to clamp the outer circle. It is just that a high-strength reinforcing rib is welded on the single-action jaw of the four-jaw chuck, and then an inner hole is welded underneath that is about the same size as the outer circle of the part blank. , The steel sleeve is evenly divided into four parts to ensure that the contact area between the steel sleeve and the outer circle of the workpiece exceeds 60%.

The biggest difficulty is not the design, but in the final finishing, it is necessary to ensure that the claw has a small angle. During the clamping process, the longer the claw is, the less force it receives. This As a result, the closer to the chuck, the greater the force when the workpiece is clamped, and the angle is calculated based on the mechanical properties of the material used for the claw.

In this way, after the jaws are tightened, the force on the parts is evenly distributed.

At this point, if you are not very experienced, you can only learn some theoretical design knowledge from books, and you cannot effectively control it at all.

It was busy until after 8 o'clock in the morning that Yunkai completed the design of the two sets of tooling, and finally produced a two-dimensional cad mechanical drawing in the form of parts.

"Eat breakfast first, you didn't sleep all night last night?" Zhao Ling, who received Yun Kai's call, asked with heartache when seeing Yun Kai's bloodshot eyes.

When Yun Kai called her, she was eating breakfast, and knew that Yun Kai hadn't eaten yet, so she brought Yun Kai a copy.

"It’s okay, I used to be like this. These drawings are our batch of working tooling drawings. You have given the materials first, what materials and specifications are there. I have to go home today and tomorrow. Just come back..." Yun Kai rubbed his eyes, and said while handing the paper with the brand name and specifications to Zhao Ling.

"You'd better sleep for a while. I don't understand the grades of these materials. Today, I have to continue to find the relevant departments to fill in the materials and purchase the office supplies. After you sleep for a while, I will send you back at night. Come back tomorrow morning to save time..." Zhao Ling didn't understand these material grades, which were all code names.

Because even the same material will have different specifications and different qualities, a layman like her simply can't figure out the doorway.

Otherwise, in military production, the consequences of substitute materials will not be so serious.

Yun Kai thought for a while and felt that the materials were not worth much. If the materials were bought wrong and the progress was delayed, then he would lose money.

Go back by yourself, but go to the house and sell the gold that the old man gave you. Whether you take a bus or a train, you will be found after going through the security check. It will be troublesome.

Zhao Ling drove herself back home!

After Yun Kai nodded, he split up with Zhao Ling.

There are a lot of phone numbers from small material suppliers who sell various materials in his mobile phone, and he knows many people.After all, in the past, Logan Factory used to open accounts and make advance payments, and Logan Factory purchases materials.

Purchasing materials is also a very technical matter. This is mainly for the increase in the amount of materials (reserved processing allowance). For small factories like Logan, if they do not do such a job well, they will spend a year on materials. It will cost hundreds of thousands more!

"Brother, you finally answered my phone. Why did you hang up my phone last night?" Yunkai just ordered the materials needed for the tooling, and was about to call the small outsourcing factories he was familiar with with better technology. Huang Kui called over the processing price of his own tooling.

"Are you busy, things are done?" Yun Fei shook his head, trying to drive away the increasingly intense randomness.

"It's done, because the paint is not dry, I won't be able to load the car until Wednesday night. I will arrive in Rongcheng on Friday morning. But I have to add 10,000 yuan. This bed was grabbed from a buddy..." Huang Kui replied embarrassedly.

"If you add 10,000, you can add 10,000, Huang Kui. Whether the domestic machining centers and CNC cars are in stock, I also hope to get them as soon as possible. Imported ones will not matter if they are delayed..." Since you don't have to go to Longguang to work now , Just do your best.

After the equipment is ordered back, it has to be installed and debugged, and various accessories and tools are configured. It also takes constant time. Before that, I just contacted my original customers.

"Numerical control cars are available in stock, but the processing center will take one month to arrive at the earliest..." Huang Kui looked embarrassed.

"I have the full payment!" Yunkai knew that for the purchase of equipment, the full payment and the mortgage, the delivery speed is much worse.

His original plan was to purchase imported equipment first, and then mortgage the domestically-made equipment according to his own funds. Now that he thinks about it, there is no need for this.

Even if you order, it will take more than five months for the machining centers and CNC cars imported from abroad to be in place.

The past few months have been the busiest time for the machining industry.
