Thanks to the wind and the big two 588 coins for the generous reward, thanks to the book friend 150721153254100 for the generous reward of 588 coins, and thank the ice mark for the generous reward. The editor has determined that this book will be on the shelves on the first of next month, and if you think that this book can still be seen, keep the money for the reward and subscribe to support it when the time comes.

On the shelves, this is definitely there. Originally, it was planned to explode more than 100,000 words on the shelves, but it seems that there is not much possibility at present, because of some things, the manuscript of the gourd has been abolished. Of course, it's still relatively early, and it has not yet been decided how much and how to explode. Brothers who have ideas can suggest ah!

··············

Liu Yijiu really didn't expect that there would be so many technicians in the third district. And they are all over thirty years old, and the young ones don't see it at all!

Xie Heping and they are really okay, obviously there are so many people, and they actually give themselves three who don't know anything! It's just too much. If you really have to design and experiment in everything from beginning to end like other firearms research institutes in China, even if you give him dozens of technicians, you may not be able to design it in three years!

"There's no problem with the process. It's just that according to the current situation, when this sniper rifle is assembled, plus the magazine and bullets, the weight of the sniper scope will be greatly exceeded. And the service life of the barrel will be much lower than the design......" Yu Jianguo shook his head and introduced the situation to Liu Yijiu.

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

No matter how polished the parts produced by machining, there is no way to achieve the surface processing quality of medium-pressure parts. The magazine doesn't matter, but the rest of the parts don't last as long as the stamped parts.

"That's for sure. However, the processing weight should not be too heavy, right? Liu Yijiu asked with a frown.

"When you designed the parts of this gun, most of the structural parts were going to be stamped, right?" Seeing Liu Yijiu nodding, Yu Jianguo further said, "The stamping parts are all stamped and formed by cold-drawn plates with high surface roughness, and the processing stress is relatively small, and the processing deformation is smaller. However, during the cutting process, stress ...... constantly occurs."

"How much will it weigh?" Liu Yijiu asked with a frown.

Type 77 12.7mm anti-materiel sniper rifle, Liu Yijiu is based on the U.S. Army Bartley M107 modified some sniper rifles 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 during design, but also reduces the gunfire and muzzle fireworks when the bullet is discharged.

The length of the gun is 1326mm, the length of the barrel is 680mm, the effective range is designed to be 2000m, the weight of the whole gun is 11.85kg, the ammunition capacity is 10 rounds, there is no mechanical sight, and the scope has not seen the sample yet, but Liu Yijiu requires that the weight cannot exceed 1.5kg. That is, the theoretical weight of the design after the addition of the scope does not exceed 13.35kg! This is not too heavy for a weight of thirty kilograms per special soldier.

After all, the bullets are carried by the sniper and the observer around him, and with other weapons and equipment, they will not exceed the range of 30 kilograms.

"About a kilogram, didn't we hand over the design drawings to you to sign after the original revision?" Yu Jianguo said speechlessly.

When they were processing, they found that if according to Liu Yijiu's requirements, it was difficult to achieve the processing, and it was difficult to make the parts not deformed during the machining process. Especially in the case of the current ordinary machining equipment.

Liu Yijiu was busy making other firearm drawings, and he didn't ask in detail, but directly signed the design change sheet that Jianguo took.

But I didn't expect such a consequence.

"Moreover, this is only the weight to achieve strength at present, and the weight will still be reduced when using stamped parts." Yu Jianguo comforted Liu Yijiu.

"Master Yu, this is not the case, the gun magazine and other parts are a lot thicker, and when we do various compression experiments and other experiments, the parameters obtained are basically of little use......" Liu Yijiu was speechless.

In this case, if the parts are changed slightly, the real data cannot be tested.

Now there is no problem with the experiment, and it will definitely not work if you change to a thinner stamping part. Then we had to do it again......

"So what do we do now? Based on this, the stamping parts will also be made of sheet metal of this thickness when mass production is carried out later? Or can we reprocess it now? Yu Jianguo was also speechless.

I knew that I should have had a good talk with Liu Yijiu at the beginning, but now it looks like the final assembly, and no one can do anything about such a problem at this time.

"The use of thickened magazines is not necessary, and it will also raise the cost of production. Not only will the weight of the material be more, but also the requirements for the mold will be higher, and the cost of opening the mold will increase accordingly......" Liu Yijiu shook his head, since he was wrong, he could only reprocess.

"But if it is reprocessed, although we only processed five samples, the cost is less than 10,000 yuan, but the time will be much later......" Yu Jianguo knew that what Liu Yijiu needed most now was time.

"There is no period. More care must be taken in the design of firearms. A kilogram of weight, if you change to other equipment, you can carry more ammunition and individual rations, which will allow our snipers to improve their battlefield survivability. Even if the mission fails, the ability to lighten the weight of one kilogram during the retreat will also allow the soldiers to run faster and farther...... "Liu Yijiu said firmly.

When this happens, we can't just go on like this.

These heavy sniper rifles were originally intended for special forces and reconnaissance units, and ordinary combat units generally do not issue such weapons.

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

"Fortunately, we only produced five guns this time, and it was only our own project, and we didn't report it, and the funding was also our own, so the loss was not big, otherwise, I really don't know how to explain it, so I immediately negotiated with the production side to re-feed and process these gun magazines...... "Liu Yijiu has no room for negotiation about 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, so he originally planned to invite Yu Jianguo to drink in the evening, but he can only give up. The people in the technical department immediately held a meeting to discuss the processing plan, and he also called Yang Shan and several people together to hold a special review meeting.

"This incident is a wake-up call for us, under any circumstances, if we do not do theoretical analysis experiments, we cannot modify the design at will. I'm at fault for this. But the three of you, when you are tracking the production and communicating with the technical process department and the production department, why is no one aware of this problem? We produce guns, do you know what this weight of one kilogram means to a soldier? Liu Yijiu first made a review by himself, and then said very seriously to the three apprentices below.

"Xiao Liu, this matter was discovered early, you are usually busy, anyway, it didn't cause much impact, plus the bullets haven't come out now, just reprocess these gun magazines, the loss is less than five hundred yuan, just remember the lesson in the future......" Xie Heping and Wang Shunyi were both called over.

The other parts were machined according to the design, and there were no problems with the magazine after the modification. The loss of five magazines is mainly the cost of materials, the consumption of tools for machining, labor, and equipment wear are negligible, and one is the cost of heat treatment......

"Director, it's not just a matter of a few hundred dollars. I ask that I be punished...... "Liu Yijiu made Yang Shan and the others realize that all aspects of weapon design and processing must not be careless in the slightest, this is not the production of previous years, and it will almost pass.

Even, even Xie Heping and others are the kind of inertial thinking in front.

Liu Yijiu can't say anything about this kind of thinking now, and the state will not begin to pay attention to this matter until the border self-defense counterattack that occurred the year after next because of the large-scale reaction of the quality of firearms in the troops, causing huge losses to the troops.

Even then, there will be that kind of thinking for decades to come.

It's impossible to influence the whole country now, but he can influence the people around him.

"What kind of punishment? As a firearms designer, it's not your design. Besides, weren't you busy at the beginning? Zheng Hao doesn't know what this kid is doing, this is obviously making trouble for himself.

I have to offend a lot of people.

"Director, we are engaged in weapon design, and we definitely can't relax in the slightest. If we still have the same attitude as before, it will eventually cause some irreparable consequences, and none of us can afford to take this responsibility! Liu Yijiu shook his head resolutely, and did not take advantage of Zheng Hao's steps to come down.

Wang Shunyi understood what Liu Yijiu meant, and nodded approvingly, there is a legacy of his father!

"That's it, we are all responsible for this matter, I was careless when I was in charge of the review, and I am also responsible. Xiao Liu signed the design modification opinion, and he was also responsible, and Yang Shan and several people were not well supervised, and each person was fined half a year's bonus to make up for this loss. In addition, it is enough to report criticism internally, and do not expand the matter. After the use of the seven-special agreement, there are a lot fewer quality problems...... "Wang Shunyi also knows that there is no benefit to this matter if it goes on like this."

If there is a major damage now, it will not be so easy to erase.

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

"Everyone's okay, right?" Zheng Hao's eyes swept around, and he saw that Yang Shan and several people were dissatisfied, and asked them.

"No comments!" Even if Yang Shan and the others have opinions in their hearts, they also know that problems with weapon design are not a joke. The three of them should bear greater responsibility, but Liu Yijiu took the responsibility for them.

This revision plan is the result of the discussion between the three of them.

Strength doesn't work? Increase the thickness of the part. Thin-walled parts are easy to process and deformation is difficult to control? It's also thicker!
