If you think that the book can still be seen, please save the reward money and subscribe to support.

It’s definitely going to happen.The original plan was to put more than 100,000 characters on the shelves, but it seems that there is not much possibility at present, because of some things, the deposit of Hulu has been abandoned.Of course, the time is still relatively early, how many and how to explode, has not been decided yet.Brothers who have ideas can suggest!

···············

Liu Yijiu really did not expect that there would be so many technicians in the three districts.And they are all over 30 years old, the young ones never saw it!

Xie Heping and the others are really okay. They obviously have so many people, and they don’t know how to give themselves three!It's too much.If you really have to design and experiment from start to finish like other gun research institutes in China, even if you give him dozens of technicians, you may not be able to design it in three years!

"The craftsmanship is not a problem. It's just that according to the current situation, the total weight of the sniper rifle, including the magazine, bullets, and sniper scope, will greatly exceed the total weight. The service life of the barrel is longer than the design. It will be much lower..." Yu Jianguo shook his head and introduced the situation to Liu Yijiu.

For trial production, in order to save costs, mechanical processing is used to obtain parts.

No matter how polished the parts produced by mechanical processing, there is no way to achieve the surface processing quality of medium-voltage parts.The gun cartridge does not matter, but the service life of other parts will not be as high as stamping parts.

"That's for sure. But the processing weight shouldn't be too heavy, right?" Liu Yijiu frowned and asked.

"When you design the parts of this gun, most of the structural parts are prepared to use stamping structure, right?" Seeing Liu Yijiu nodded, Yu Jianguo further said, "Stamping parts are made of high surface roughness. Cold-drawn sheet metal stamping and forming, the processing stress is relatively small, the processing deformation is smaller. However, during the cutting process, stress is constantly generated..."

"How much will it weigh?" Liu Yijiu asked, frowning.

Type 77 12.7mm anti-material sniper rifle, Liu Yijiu modified some sniper rifles based on the US Army's Bartley m107 that are more in line with the ** use habits.The muzzle brake adopts the cylindrical design of m107a1, which not only effectively reduces the recoil of the design, but also reduces the sound of the gun and the muzzle fireworks when the bullet is ejected.

The full gun length is 1326mm, the barrel length is 680mm, the designed effective range is 2000m, the full gun weight is 11.85kg, the ammunition capacity is 10 rounds, there is no mechanical sight, and the scope has not yet seen samples, but Liu Yijiu requires the weight not to exceed 1.5kg.In other words, the theoretical design weight after installing the scope is no more than 13.35kg!This is not too heavy for the 30 kilograms of each special soldier.

After all, the bullet was carried by the sniper and the observers around him separately, and other weapons and equipment would not exceed the range of 30 kilograms.

"It's about one kilogram, didn't we give you the design drawings for signature after the original revision?" Yu Jianguo said silently.

When they were processing it, they found that if they followed Liu Yijiu's requirements, the processing would be difficult to achieve. During the machining process, it would be difficult to keep the parts from deforming.Especially in the current case of ordinary machining equipment.

Liu Yijiu was busy getting other drawings of the firearms, and he didn't inquire in detail. It was because the design change form that Jianguo had brought was signed.

But did not expect such consequences.

"Moreover, this is only the weight currently in order to achieve strength. When stamping parts are used, the weight will still drop." Yu Jianguo comforted Liu Yijiu.

"Master Yu, this is not the case. The gun case and other parts are much thicker. When we do various compression experiments and other experiments, the parameters obtained are basically of little use..." Liu Yi Nine is speechless.

For this thing, if the parts change slightly, the real data cannot be tested.

There is no problem with the experiment now, and it is definitely not possible to replace it with a thinner stamping part.Then I have to re-experiment...

"Then what shall we do now? Just use this as a blueprint, and stamping parts with this thickness will also be used in mass production later? Or shall we reprocess it now?" Yu Jianguo was speechless.

I knew it a long time ago that I should have had a good talk with Liu Yijiu at the beginning. It seems that the final assembly is about to happen. No one can help if such a problem arises.

"Using a thicker gun case is unnecessary, and it will also increase the production cost. Not only will the material weight be higher, but also the mold will be more demanding, and the mold opening cost will increase accordingly..." Liu Yijiu I shook my head, since it was wrong, I can only reprocess it.

"But if we reprocessed, although we only processed five samples, the cost was less than 10,000 yuan, but the time would have to be a lot at night..." Yu Jianguo knew that what Liu Yijiu needs most now is time.

"There is no period. We must be more cautious in the design of firearms. If the weight of one kilogram is replaced with other equipment, we can carry more ammunition and individual rations, which will allow our snipers to improve their battlefield survivability. Even if the mission fails, one kilogram of weight can be reduced during the retreat, and the soldiers can run faster and farther..." Liu Yijiu said firmly.

If this situation occurs, it absolutely cannot go on like this.

These heavy sniper rifles were originally prepared for special forces and reconnaissance forces. Ordinary combat forces generally do not issue such weapons.

"Now, since we all have to bear the consequences..." Upon hearing Liu Yijiu's words, Yu Jianguo said with a wry smile.

"Fortunately, we only produced five of them this time, and they were only our own projects. We did not report them. The cost is our own. The loss is not big. Otherwise, I really don’t know how to explain it. I will negotiate with the production side immediately. , Put these gun cartridges into processing again..." Liu Yijiu had no room for discussion on this matter.

I really don't know how Yang Shan and the others stared at this.

Liu Yijiu himself is also responsible for this, and he can't blame them. He originally planned to invite Yu Jianguo to drink in the evening, but he could only give up.People in the technical department immediately held a meeting to discuss the processing plan, and he also called Yang Shan together to hold a review meeting.

"This incident has sounded a wake-up call for us. Under any circumstances, if you have not done theoretical analysis and experimentation, you cannot modify the design at will. This is my fault. But the three of you are tracking the production and the technical process. When the Ministry and the production department communicated, why didn’t anyone realize this problem? We produce guns. Do you know what the heavier kilogram means to soldiers?” Liu Yijiu first made a review by himself. Then he said seriously to the three apprentices below.

"Xiao Liu, this matter was discovered early. You are usually busy. Anyway, it didn't cause much impact. Besides, the bullets have not come out now. Just reprocess these gun cartridges. The loss is less than 500 yuan. Just remember the lesson in the future..." Xie Heping and Wang Shunyi were both called over.

Other parts are processed according to the design, and there is no problem after the gun case is modified.The five gun cartridges lost are mainly the cost of materials, tool consumption for machining, labor, and equipment wear can be ignored. One is the cost of heat treatment...

"Director, this is not just a matter of a few hundred dollars. I request that I be punished..." Liu Yijiu wanted to make Yang Shan realize that all the links in weapon design and processing must not be careless. This is not The production of the previous few years will almost pass.

Even Xie Heping is the same kind of habitual thinking.

With this kind of thinking, Liu Yijiu can’t say anything now. The country will only begin to pay attention to it until the firearms quality problem has been reflected in the army on a large scale during the border self-defense counterattack the following year, causing huge losses to the army thing.

Even so, there will be such thoughts in the next few decades.

It is impossible to influence the country now, but he can influence the people around him.

"What's the punishment? As a gun designer, it's not your design problem. Besides, weren't you busy at the beginning?" Zheng Hao didn't know what the trouble was with this kid, it was obviously to find himself awkward.

Also offend a lot of people.

"Director, when we are engaged in weapon design, we absolutely cannot relax in the slightest. If we still have the original attitude that is almost the same, it will eventually cause some irreparable consequences. None of us can bear this responsibility! "Liu Yijiu shook his head resolutely, not using Zheng Hao's steps to get down.

Wang Shunyi understood Liu Yijiu's meaning and nodded approvingly, with his father's legacy!

"Well, we are all responsible for this matter. When I was in charge of the review, I was careless, and I was also responsible. Xiao Liu signed the design revisions and was also responsible. Yang Shan and several people did not supervise well, and each of them deducted half a year of bonuses. Make up for this loss. In addition, it is enough to report criticism internally. Do not expand this matter. After the use of the seven-special agreement, the quality problems have been reduced a lot..." Wang Shunyi also knows that this matter continues to do no good.

If major losses are caused now, it will not be so easy to smooth out.

The problem is mainly in their project team, which has nothing to do with the technical department and production department, so there is no need to entangle these things.

"Everyone doesn't have any opinions?" Zheng Hao glanced around, and when he saw that Yang Shan was dissatisfied, he asked them.

"No opinion!" Even if Yang Shan had opinions in their hearts, they knew that problems with the weapon design were not a joke.The three of them should bear greater responsibility here, but Liu Yijiu took the responsibility to them.

This modification plan is the result of the three of them discussed.

Not strong?Increase the thickness of the part.Thin-walled parts are easy to process and deformation is difficult to control?It's thicker too!
