At work the next day, Li Guocheng very scoundrelly threw the information of Yan Jiefang and Zhang Meihua to Wu Liankui.

"Director, you are tired, help to do it together."

Wu Liankui reluctantly picked up the information and scolded with a smile: "I really owe you, am I the director, or are you the director?" ”

"Can you work more! A meal from the east to the east, you see if it's okay", Li Guocheng took the opportunity to treat and contact his feelings.

"Okay, I don't have time this weekend, next Sunday, we just get together together, don't you have a partner, we will all bring it out to get to know each other when we arrive", Wu Liankui also had this intention.

"Try your best, my object often travels on business, the time is not easy to set, I will give you news at 6 next week", Li Guocheng is also helpless, since he has chosen, he can only understand and support.

"Okay, we'll find out next week."

"By the way, the drawings of my semi-automatic lathe have been completed, and Zhou Xiaojuan is responsible for the follow-up work, just to exercise her work coordination ability. Now Wang Gong is completely obsessed with the thermal stress relief process, and Master Yi is staring at the click group again, and the experienced manpower is still insufficient", Li Guocheng said the purpose of cultivating Zhou Xiaojuan.

"Aren't you afraid that the little girl will be angry and cry by the rough old men in the workshop?" , Wu Liankui urged the narrow road.

"If you want to do things, you have to face these things, and slowly adapt to them", Li Guocheng feels that it doesn't matter, this is what growth must face.

"Those guys are not bad, they just love to play tricks on newcomers, but there are also some wilting things, you have to take precautions in advance", Wu Liankui still felt that a little girl was a little difficult to face the rough old men in the workshop, and she had to take insurance.

"Don't worry, don't dare to give face to the laboratory, and see how I clean them up then", Li Guocheng came out of the workshop, he has seen a lot of dirty things, and he knows how to deal with them.

After Li Guocheng said hello, he came to Zhou Xiaojuan's workstation.

"Xiao Zhou, after the drawings are approved, the technical department will decompose the task, and then the factory office will be assigned to the relevant workshops, and the production of all parts will be coordinated by you and the workshop, including the technical system, tracking progress, tracking inspection and checking data, do you have the confidence to win?"

After listening to this, Zhou Xiaojuan was excited and worried, after all, Wang Gong was not responsible for the previous work, or Master Yi was in charge, and she was the first time in her life that the eldest girl got on the sedan chair. Thinking of coming to "get on the sedan chair", his face suddenly turned red, and he secretly glanced at Li Guocheng.

"Director, if you think I can do it, I'll do it," Zhou Xiaojuan assured.

"That's okay, learn more from Wang Gong and Master Yi, if you encounter any problems, you can't solve them yourself, remember to find me."

When Zhou Xiaojuan heard this, she began to feel sorry again. Li Guocheng saw that she didn't respond, so he pushed her, "Hey, wake up."

"Hey, I know", Zhou Xiaojuan blushed and immediately responded.

Li Guocheng looked at Zhou Xiaojuan's current performance, and he was helpless, he didn't listen to her, and he always felt that he was lying to him.

Li Guocheng came to the processing workshop of the laboratory, picked up the parts that were not finished yesterday and walked to the only Dawn 1966 machine tool, and began to process the core components of the semi-automatic machine tool, that is, the dial of the setting of the feed depth and the automatic parking module, because there is no microprocessor, these works must be completed by the mechanical structure.

In the previous stage, the now only Dawn 1966 machine was moved to the laboratory machine shop for precision machining and experimentation.

The dial imitates the principle of spiral micrometer design, composed of three layers of dials, from low to high are large plates, middle plates and small plates, the minimum scale of the large plate is 10mm, the minimum scale of the middle plate is 0.1mm, the minimum scale of the small plate is 0.005mm, the theory of the overall fit can reach 0.005mm, the actual should be able to reach 0.01mm, which is already the highest precision of the current domestic machine tool.

The internal imitation of the watch hairspring principle, coupled with the precision gear set, is like a timer, after setting the walking distance, slowly reduce the set value, after returning to zero, trigger the parking module, get out of the lead screw, and play the purpose of parking.

A manual switch is set on the walking trailer, and longitudinal and transverse driving can be selected. The switching is done by the gear set inside the hanging box, like the gear knob of a car, and because the switching is done at a standstill, there is no need for a clutch.

The steel processed now is the experimental product of Wang Gong's high-temperature stress relief, which happened to be snatched by Li Guocheng to refine this part of the part. When you rebuild the Dawning 1966 machine, you spent most of your time waiting for the stress to be relieved.

Li Guocheng is responsible for the machining volume to be completed in half a month at most, and the next key is the selection of the hairspring, which is limited by the material and only has drawings. Through Aunt Liu's help to find the relevant departments, but basically did not meet the requirements, instead of waiting, it is better to find a way to experiment, do not forget that this is a rolling mill, which has special steel production capacity.

By searching for information, the technical requirements of the hairspring are:

1. It has a given elastic characteristic;

2. Less elastic hysteresis;

3. Small temperature coefficient (thermoelastic coefficient);

4. Good anti-magnetic performance and corrosion resistance;

5. The pitch is equal;

6. The center of gravity of the wire should be consistent with the geometric center as much as possible.

Most of the above properties are related to materials, and processing is the easiest for Li Guocheng. Through the data, it is known that the Archimedes spiral coil spring formed by cold rolling, winding and shaping of the metal filament for the hairspring is an elastic element that can produce reaction moments.

This task can be entrusted to Master Yi, and he needs to consider how to achieve the synchronization relationship between the hairspring and the lead screw.

Two days later, Master Yi was found to communicate the realizability of a professional hairspring.

"Xiao Li, I have found the engineer who is best at material research in the technical department to help design and experiment, the first five are easy to implement, but the last one has no professional tools, and there is no way to achieve the design requirements of 'the center of gravity of the silk should be as consistent as possible with the geometric center'", Master Yi has been obviously haggard a lot these days.

After thinking about his original design, the synchronization has not been completely done now, and now the hairspring is more difficult to do, so there is no need to continue the original design, after nailing the idea, Li Guocheng said: "Uncle Yi, it is very good to be able to meet the first 5, you help produce 10 samples according to the drawings, I will modify the design, the existing hairspring should be enough."

Hearing that the requirements could be met, Uncle Yi was obviously relieved.

Li Guocheng sketched on the drawings, and finally gave up the synchronous linkage, added a set of gears, drove the hairspring to rotate, and the hairspring only completed the length measurement work, removing the previous active function.

After figuring it out, I started to revise the drawings, and finally completed it before leaving work, so that the manufacturing problems of the semi-automatic lathe were all solved, and the next step was to wait for the processing of other parts.

At that time, Li Guocheng will complete the finishing by himself, with the first high-precision machine tool, then the follow-up mass production machine tool is like a chicken laying eggs, eggs and chickens, as long as the funds are enough, the overall improvement of the country's basic processing capacity will be completed soon. This is the power of the industrial machine, and it is completely positive.

Think about the future generations, due to the blockade of technology, the big brother also has bad intentions, and the talent has not grown up, resulting in the loss of the ability of domestic machine tools to lose their ability to innovate, only pay attention to the quantity and do not pay attention to scientific research, the quality of the production of machine tools does not rise but falls, the maintenance cost of machine tools increases, the use of such machine tools to produce products defective rate increased sharply, resulting in a great waste of resources.

After the change, the production enterprises are resistant to domestic machine tools, have applied to buy foreign products, even if foreign machine tools have been eliminated than the domestic too advanced, that is behind the least two generations of technology, foreign machine tool manufacturers to see this good thing, a large number of dumping, further compressed the domestic machine tool progress space, until the new century has improved.
