Chapter 223, Disassembly

Since there were two engineers helping Jiang Yan, the disassembly was quite fast.

For a moment, tools such as vise, screwdriver, and hammer were flying in Jiang Yan's legs, and parts such as cover plates, bearings, spindles, tie rods, etc. were being dismantled from the machine one by one.

Jiang Yan made a rough assessment of the parts that were disassembled from Donglai. Depending on the degree of wear of the parts, those parts were numbered and carefully put aside.

With the technical background from his previous life, Jiang Yan also basically knew the general function of those wrong parts. After all, he had dismantled so many machines in his previous life.

Regarding the convenience of work, Jiang Yan specifically asked Guo Jianjun to find a recorder. The recorder clearly marked which parts and gears were redundant, which lines were incorrect, and other basic information about the disassembled parts.

It wasn't until the entire bed was dismantled into an iron shell that Jiang Yan stopped working on his legs.

"Gong Jiang, Gong Wang, and Gong Zhang will eat first. After dinner, we will work together."

Hearing Guo Jianjun's words, Jiang Yan raised his leg and wrist in confusion and looked at his wrist watch. The time had already reached 1:30.

At that time, my stomach also started growling.

He took the lunch box from Guo Jianjun's lap and opened it. Several people found a random work station and walked there to open the lunch box.

"The food we have there is very good." Jiang Yan said as he looked at the meat and vegetables in his lunch box, including pork stewed vermicelli, fried potatoes and rice.

"That's great! They are a military factory there, and supply prices are relatively high. Plus, they are in the northeast and have abundant products."

Seeing Guo Jianjun's somewhat proud words, Jiang Yan added a piece of pork belly and ate it in his mouth before speaking leisurely.

"Then it's wrong to beat the roe deer with a stick and scoop up the fish and pheasant into the rice pot!"

"Wrong, that's how I described it. Although it's not very accurate, it's almost the same as in Bu Nao. That sentence mainly describes the Great Northern Wilderness. Bu Nao has a lot of game in the wild. Get some for me when you have time."

"Thank you very much." Jiang Yan ate a mouthful of rice and said thank you.

Wang and Zhang, two very technical people, were discussing some issues with Jiang Yan during the meal.

Jiang Yan was helpless and answered while eating.

After finishing his meal, Jiang Yan rested for a while and then brought two engineers from Wei Dai back to the fine segment machine.

During the disassembly at noon, Jiang Yan had already discovered the damaged area of ​​the machine.

It is very simple to explain clearly. Is it possible that the balls inside the ball shaft are damaged or missing? If it runs like this, it will cause the machine to overheat and the screw to lock up, causing the teeth to slip.

If such a situation occurs, the accuracy of the machine will decrease, which will indirectly cause the machine to be scrapped.

By then, the damage to other machine parts was not that serious, it was just a matter of lack of maintenance.

Fortunately, the damage to the motor was not that serious, which can be considered a blessing among misfortunes.

What Jiang Yanqiu wants to do now is to restore the drawings of various parts.

With those three-dimensional drawings, parts can be mass-produced on a large scale, and there is no need to worry about damaging the machine and running out of parts.

With those three-dimensional drawings of machine parts, reverse engineering is not a big problem.

If the amount of work in Bu Nao is not small, I can concentrate on the drawings. At this time, there are two engineers and Jiang Yan outside the workshop. The other workers have been arranged by Jianjun to other workshops.

With him following him, he could listen to Jiang Yan and the others' arrangements at any time.

After dinner, under Jiang Yan's command, the three of them started to get busy.

Measuring, drawing, and calibrating, it was a great time for three people.

The three people were completely immersed in their work physically and mentally, completely forgetting what was going on around them.

When the three of them were leaving for Lu, Director Zhao and the factory leaders came to the workshop where Jiang Yan and the others were located.

Director Zhao, who had just entered the workshop, saw parts covering almost the entire floor of the workshop. Next to each part was a piece of paper with some Arabic numerals written on it. He didn't know what those numbers meant.

Originally, Factory Director Zhao and other leaders from outside the factory came there tomorrow to formally announce that Jiang Yan would be the leader of the plant's machinery maintenance team. By the way, he introduced Jiang Yan to the leaders, but he saw what he saw in front of him.

One scene.

Guo Jianjun had already noticed the factory leader who came in. When he saw that the factory director was about to speak, he quickly walked forward and made a silencing leg gesture to the factory director.

Does he know that what Jiang Yan and the others are doing now is very important and must not be disturbed. Otherwise, he will not dare to shut up the factory director even if he is beaten to death.

The factory director was stunned when he saw Guo Jianjun's leg posture, and his mouth that had just opened closed again.

When Guo Jianjun saw that the factory director refused to shut up, he pulled the factory director and the others outside the workshop.

"Xiao Guo, what are they doing?" Director Zhao asked Guo Jianjun after leaving the workshop.

"Director, Gong Jiang, Gong Wang and Gong Zhang have dismantled the fine segmenting machine and are now repairing the parts on the wrong machine for drawing. You really can't disturb them now, I'm really sorry."

After hearing Guo Jianjun's words, Director Zhao looked very depressed.

As the owner of a factory, there is never a place where I am not allowed to shut up.

"Why did he play the piano randomly? He didn't report it to the factory leaders, so he dismantled the machine privately. Is that really unorganized and undisciplined? No, it's up to him to stop them."

A man about forty years old with glasses who was following Director Zhao scolded him and wanted to enter.

However, he was grabbed by Zhao Chang.

The man wearing glasses is named Zhou Fou, the deputy director of management technology at Liuliusan Factory.

At that time, the deputy director Zhou was very worried. I didn’t know what happened to the machines in the factory at that time. Various situations occurred. Most of his engineers were sent east, and they were working hard to repair them.

machine.

There are only two fine-segmenting machines maintained by Jiang Yan and others in the entire factory. Can they be used to manufacture the main machine for gun barrels? Although the accuracy of that machine is somewhat degraded, it is basically usable if it is just one machine. I wonder if that machine is missing.

, just relying on the left one, it is estimated that the tasks outside the factory may not be completed next year.

The manufacturing of gun barrels is divided into cold forging technology and traditional deep hole processing technology.

The gun barrel manufactured by the fine section machine belongs to the cold section process.

The so-called "cold forging" probably follows the process flow: first, punch a hole in the center of a blank that has been initially forged, heat treated, and surface finished, and use a steel outer core with the same pattern as the rifling to pass through it.

Then one end is stuck in the chuck of the cold forging machine, and four hammer heads made of brass rotate slowly in the chuck of the cold forging machine to evenly beat the blank to make it elongate and finally turn into a piece of qualified size.

barrel.

Outside the factory, except for the two fine section machines that can use the cold section process to manufacture pipes.

The rest all use traditional deep hole processing technology.

To put it simply, deep hole processing rifling: use a boring machine and a long rifling broach to cut out the yin and yang rifling outside the barrel blank bit by bit.

The general process flow also requires a finished gun barrel blank (the size has been determined). One end of the blank is stuck on the chuck of the boring machine, and a hole needs to be drilled in the center, and then the broach is inserted to process the rifling.

The process of processing fine and deep holes like gun barrels is relatively difficult, because the rifling is done on the outside and the external conditions cannot be seen from the outside. It is possible to rely on the experience of senior technicians to complete the processing.

They can make gun barrels faster than bananas, and the barrels can be folded slowly and finely.

The barrels made by those two precision segmenting machines account for half of the entire factory's barrel manufacturing.

If that situation arises, why don't you, as the deputy director in charge of technology, be in a hurry?
