"After the children go to school, they have to go home at night and live in the school, which is not a good thing for them!" It is not a good thing for children who have not been cultivated to be independent since childhood, and as soon as they enter the city, let them go to school to live in school. (Please search for the fastest novel website!)

The current school is not very strict in the management of this aspect, once these children have early love or something, when there is a problem, they can't find a place to cry.

In particular, two of the three children in the family are girls, and they are still beautiful little girls......

"Then you have to live with us even more, now I can't control them more and more......" Yun Su said quietly, it's okay for her daughter, but for Hu Zhen and Hu Bao, the two brothers and sisters, she can't be too strict as an aunt, otherwise she can't explain if she lets these two bear children run away from home.

"Let's wait a few days, I'll find someone to find a way to get the school done for them in the next two days, and then let's talk about it, when the equipment in my factory arrives, it is estimated that there will not be much time to come back at that time!" If you guys are naughty and disobedient again, I'll send you back! Yun Kai threatened a few bear children.

These bear children are about to enter a rebellious period, and they can't be suppressed by force.

Yun Kai was going to take them out to eat, but was stopped by Yun Su, eating out, no matter how economical a few people are, they have to spend more than a hundred, at home, buy some meat, buy some vegetables, it is only thirty or forty yuan.

Several children are growing up, in the past, in the hometown, it is rare to see meat for a while, here, with an uncle, I don't worry about living the hard life before.

When Yun Kai was there, a few bear children didn't dare to make any more tricks, and when they left, they threatened to send anyone back if they were disobedient, and then Yun Kai rode his second-hand old bicycle to the factory he rented in Zhongda Mold Industrial Park.

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

Time is tight.

This had to be done before the equipment came back, and at the same time had to go back to the hometown and bring the gold from home to sell.

Otherwise, the money in his hands would not have been able to purchase equipment at all.

It takes a long time for imported equipment to be in place, and now he hasn't even asked about the price, so it's impossible to buy these imported equipment in the first place.

With the value of that gold, it is more than enough to pay for the price of domestic equipment.

As for the business, Yi Yunkai has been in this industry for so many years, will there be a shortage of business? It would be better if the Longguang factory collapsed, and they would take over all their business by themselves, and they would not have the slightest sense of guilt.

If Long Guang still belonged to Wu Feng and robbed him of his business, it would be impossible to say that there was no sense of guilt.

"Why did you come back so early today?" When Yun Kai returned to his nest, Hu Xiaolong's goods seemed to have just gotten up, and he had just come back with a box of instant noodles.

"Come back and draw! Let's go and get some snacks and snacks on the whole day, and I have to stay up late tonight to catch up with work......" Yun Kai entered his house after throwing two hundred yuan to Hu Xiaolong.

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

The tooling design of the car reference is relatively simple, as long as the force point of the part is more, so as to avoid the force point is too small and the whole workpiece concentrates all the weight and torque generated in the rotation process to one point, so as to cause damage to the part.

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

When clamping, on the rubber pad with a large coefficient of friction, this makes the soft contact between the tooling and the workpiece, so as to avoid the pure tungsten thin-walled parts that are sintered together by high temperature and high pressure without any adhesive because of too much force at a certain point.

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

However, this is not a difficult thing for Yunkai at all, the middle of the tooling matrix uses a conical steel sleeve, which is connected to a large section of the steel sleeve with a screw, so that the screw can be tightened during clamping to support the support column on the inner wall of the workpiece at the same time.

Of course, this adjustable amplitude is only the final fine-tuning, and the purpose is to allow the sixteen support columns to apply force to the parts at the same time to ensure the uniformity of the force.

Just such a thing, Yun Kai was allowed to do it from after three o'clock in the afternoon to twelve o'clock in the evening, and even Huang Kui's call was hung up by him.

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

The clamping outer circle tooling is slightly simpler than this, just weld a stiffener with high strength on the single-action jaw of the four-jaw chuck, and then weld an inner hole that is about the same size as the outer circle of the part blank, evenly divided into four parts of the steel sleeve, to ensure that the contact area between the steel sleeve and the outer circle of the workpiece is more than 60%.

The biggest difficulty is not the design, but in the final finishing, it is necessary to ensure that the jaw has a small angle, the longer the jaw in the clamping process, the longer the force will be received, which causes the force to be greater when clamping the workpiece, the closer to the chuck, and the angle is calculated according to the mechanical properties of the material of the jaw.

In this way, the force on the part is evenly distributed after the jaw is tightened.

If you are not very experienced, you will not be able to effectively control this point if you learn some theoretical design knowledge from books.

It was not until after eight o'clock in the morning that Yunkai completed the design of these two sets of tooling, and finally made a two-dimensional netbsp in the form of parts; "Eat breakfast first, you didn't sleep all night last night?" Zhao Ling, who received Yun Kai's call, saw Yun Kai's bloodshot eyes and asked bitterly.

When Yun Kai called her, she was eating breakfast, and knowing that Yun Kai hadn't eaten yet, she brought one for Yun Kai.

"It's okay, I used to boil like this a lot. These drawings are our batch of live tooling drawings, you give the materials first, what materials, what specifications, these drawings are all on it, I have to go home today, and I'll be back tomorrow......" Yun Kai rubbed his eyes, and said while handing the paper with the brand number and specifications to Zhao Ling.

"You better sleep for a while, I don't understand the grades of these materials, I have to continue to find those relevant departments to fill in the information and purchase those office supplies today, I will send you back at night after you sleep for a while, and then come back tomorrow morning, so as to save time......" Zhao Ling didn't understand these all code-named material grades.

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

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

Yun Kai thought about it and felt that it was also, these materials were not worth much, if the progress was delayed because the materials were bought wrongly, it would be a loss at that time.

If you go back by yourself, you can go home and sell the gold given by those old men, whether you take a bus or a train, you will be seen after the security check, and it will be a troublesome thing at that time.

Zhao Ling drove herself back!

Yun Kai nodded, and then acted separately with Zhao Ling.

His mobile phone contains the phone numbers of many small material suppliers who have opened zero for various materials, and he knows many people. After all, many of the previous businesses of the Longguang factory were to open an account and make advance payments, and the Longguang factory purchased materials.

The purchase of materials is also a very technical thing, this is mainly in the amount of materials (reserved processing allowance) on the top, such a small factory like Longguang, if you do not do such a good job, a year on the material will spend hundreds of thousands!

"Brother, you finally answered my phone, why did you hang up on me last night?" Yun Kai had just set the materials needed for those toolings, and was about to call the small outsourcing factories with better technology that he was familiar with to ask about the processing price of his tooling, and Huang Kui called.

"Busy, it's done?" Yun Fei shook his head, trying to drive away the increasingly intense randomness.

"It's done, because the paint is not dry, it won't be loaded until Wednesday night, and it will probably arrive in Rongcheng on Friday morning. But I have to add 10,000 yuan, I snatched this bed from a buddy......" Huang Kui replied embarrassedly on the phone.

"Add 10,000 to add 10,000, Huang Kui, those domestic machining centers and CNC lathes, whether they are in stock, I also hope that I can do it, imported, it doesn't matter if it's late......" Since you don't have to go to Longguang to work now, you can simply do your best.

After the equipment is ordered, it is necessary to install and debug, configure various accessories and tools, and it also takes a lot of time.

"CNC lathes are in stock, but the machining center will take a month to arrive at the earliest......" Huang Kui looked embarrassed.

"I'll pay in full!" Yunkai knows that when buying equipment, the full payment is much worse than the mortgage.

His original plan was to buy imported equipment first, and then mortgage the domestic equipment according to the funds in his hands, but now that he thinks about it, there is no need for this at all.

Even if ordered, it will take more than five months for the machining center and CNC lathe imported from abroad to be in place.

These are the busiest months in the machining industry.
