Chapter 47 Fuze
Wanshan factory in accordance with Lu Jiadong's plan, quickly drafted the approval documents, reported to the provincial Department of science, technology and industry for national defense, as Lu Jiadong expected, the Department of science, technology and industry for national defense saw that it was the 78 type assault rifle supporting tactical accessories, without saying a word on the sign and approved, not only that, but also allocated 40,000 yuan of research and development funds to Wanshan factory by the way, when Chen Zhen received the approval of the provincial department, he summoned Lu Jiadong, Wu Tianming, Qiao Junfeng, Yang Limin, Li Deshun, Chen Zihao and other members of the Type 78 assault rifle development team changed their names to the gun-mounted grenade launcher development group.
However, unlike the previous firearms development team, Chen Zhen, as the director of the factory, did not serve as the team leader, but quoted the name of the chief designer, of course, this name finally fell on Lu Jiadong's head without any suspense, in order to facilitate the work of Lu Jiadong, the chief designer, the factory party committee decided to transfer the work of Lu Jiadong and Qiao Junfeng, with Qiao Junfeng as the workshop director and Lu Jiadong as the technical section chief.
In this way, after some personnel transfers and preliminary preparations, the gun-mounted grenade launcher development team led by Lu Jiadong was officially put into operation, and the gun-mounted grenade launcher did not have much advanced technology, and the basic structure was similar to that of a shotgun, using a single shot and a single shot, so it had a trigger, firing pin, insurance and other mechanisms, but there was no bolt and bolt.
If you want to say that it is complicated, it is only the ammunition fixing mechanism proposed by Lu Jiadong, because Lu Jiadong proposed to use an integrated grenade, so that after the grenade is fired, the action of rejecting the shell is omitted, although the action of retracting the shell is short, but it is extremely valuable in the ever-changing battlefield, because the soldier who is exempted from this action can raise the gun to shoot at the first time, and can also quickly load the next grenade for fire support.
Because of this, the grenade is only the best choice to fill from the boring port, but the boring filling involves the problem of fixing the ammunition in the launcher, otherwise the ammunition will slide out of the boring at any time, although this problem is very complicated, but Lu Jiadong cleverly solved it, he set up a fixed spring in the grenade launcher, and installed a fixed pin pressure plate outside, when the ammunition is loaded and the fixed pin pressure plate is moved, the ammunition is fixed in the chamber, on the contrary, push the fixed pin pressure plate, and the ammunition can be safely debored!
As for the production process, it is not a problem, most of the gun-mounted grenade launchers are made of high-strength aluminum alloy, which can be completed by the labor service company of the Wanshan factory, not to mention the military workshop, the maximum diameter of the barrel boring drilling rig in the factory is 40mm, and the gun-mounted grenade launcher designed by Lu Jiadong is only 40mm, so there is no technical obstacle to the most important body barrel processing.
As for the process problems such as heat treatment, rifling, firing pin processing, and sight calibration, there are no difficulties in the Wanshan factory, because after the successful development and production of the Type 78 assault rifle, the Wanshan factory has made great improvements in technology research and development, product design, and processing and manufacturing.
But Lu Jiadong was not happy because of the fast progress of development, because they encountered a problem that they had never thought about before -- there was no matching ammunition.
Originally, Lu Jiadong didn't think that ammunition was a big problem, after all, Wanshan Factory had produced ** before, and he had some experience in ammunition production, so he handed over the development task of the 40mm grenade matching the gun-mounted grenade launcher to Qiao Junfeng, and he concentrated on solving the problem of the launcher itself.
But this afternoon, Qiao Junfeng hurriedly came to the location of the research and development team, the technical department of the factory, and said straight to the point as soon as he entered the door that the factory could not produce 40mm ammunition that matched it.
It just so happened that Chen Zhen was also here, and he couldn't help frowning after listening to Qiao Junfeng's words: "Old Qiao, I remember that our factory has experience in producing ammunition, how is it possible?"
"Fuse!" Before Chen Zhen finished speaking, Qiao Junfeng couldn't wait to answer, and then he picked up the teacup on the table and drank two sips of water, and then wiped his mouth with his sleeve:
"Our factory has produced **, and has also made simple bump fuses, but that was how many years ago, the accumulated technology has been tossed away after a special period of turmoil, and the machinery and equipment are also aging, and they have long lost their production capacity!"
Yang Limin put down the pen in his hand, picked up the teacup and poured a glass of water, and handed it to Qiao Junfeng: "Didn't our factory pull back a few precision machine tools last year?
Qiao Junfeng took the water, nodded slightly to express his gratitude, and then continued: "We also looked at those precision machine tools, all the tools were damaged, the scale of the indexer was blurred, and we could only barely process ordinary parts, and the precision parts in the fuse could not be processed at all!"
"Director Qiao is right!" Lu Jiadong, who had not spoken, also stopped what he was doing at this time and stood up: "When the firearms were produced, Master Li and I checked all the equipment pulled from the factory, and those precision machine tools were indeed not accurate enough, so they could only be put in the workshop for rough machining!"
As soon as Lu Jiadong's words fell, Wu Tianming frowned and said, "In this case, wouldn't our gun-mounted grenade launcher become a pile of scrap metal with guns and bullets?"
Wu Tianming's words made the people in the room not know how to answer, they all chose silence, and I don't know how long this silence lasted, Lu Jiadong, who was sitting in the corner, rotated the teacup in his hand, and said something that seemed to be nothing:
"Why don't we go to the old factory director and try it!"
"Old factory director?" Qiao Junfeng repeated, and then slapped his thigh: "That's right, isn't our old factory director just the director of the ammunition factory, won't this matter be solved by him!"
The old factory director in the mouths of Lu Jiadong and Qiao Junfeng is none other than Zheng Yongbo, the former director of the Wanshan Factory, who is now transferred to the ammunition factory as the director, which belongs to the provincial key military factory, mainly producing various types of ammunition, supporting fuses and some precision instruments, so this factory is different from the ordinary military factory only called XX Machinery Factory to the outside world, but the word precision is crowned in front of the machine, so the full name is Guinan Precision Machinery Factory.
Because of this, after Lu Jiadong finished talking to the old factory director to try, Qiao Junfeng was so excited, not only Qiao Junfeng, but everyone else in the room also showed a happy smile, for a provincial key ammunition factory, the production of 40mm grenades is simply a piece of cake, not to mention that the factory director is Zheng Yongbo, who was born in Wanshan, if he is found, not like a family, this problem will be solved in minutes.
So when Qiao Junfeng finished saying this, whether it was Chen Zhen or Wu Tianming, and even Yang Limin, who was not good at words, felt that the dark clouds that were lingering on everyone's heads had dispersed, and Wu Tianming stood up and was about to send a telegram to the old factory director Zheng Yongbo, but before Wu Tianming could open his legs, he was stopped by Lu Jiadong, who was very puzzled by Lu Jiadong's actions:
"Jiadong, what are you?"
Lu Jiadong just stopped Wu Tianming, but did not answer his question, but looked at Chen Zhen and knocked on Qiao Junfeng again: "Director Chen, Director Qiao, do you think we should entrust them to produce well, or master the technology, and we can make it ourselves?"
"Of course, it is best to produce by yourself, so as not to be affected by others, Xiaolu, what do you mean?" Qiao Junfeng replied without hesitation after Lu Jiadong finished asking, but he felt that something was wrong as he spoke, so he stopped and asked Lu Jiadong.
After listening to Qiao Junfeng's question, a calm smile appeared on Lu Jiadong's face: "My meaning is very simple, instead of entrusting them to produce, it is better to import machinery from them and come back, and we will build it ourselves!"
"Make it yourself?" Chen Zhen repeated.
"That's right!" Lu Jiadong's tone was very firm, and his words were not muddy: "Our factory can now produce Type 78 assault rifles and gun-mounted grenade launchers, which proves that we do not have technical problems in small-caliber body-controlled weapons, but there are shortcomings in ammunition."
However, from the point of view of ammunition machining technology, there are no defects in the processing of the most difficult cartridge belt, but in terms of fuze manufacturing, our factory is lagging behind a lot, and I want to take this opportunity to make up for the shortcomings of our factory, so that our factory can be regarded as a veritable comprehensive military factory!"
"Comprehensive military factory!" Chen Zhen nodded: "Very good, Xiao Lu's proposal is really good!** once said to be self-reliant, although the current conditions are better than before, but the spirit of self-reliance still cannot be lost, Xiao Lu is right, instead of letting them produce, it is better for us to learn to make our own products, this time we will take the opportunity to develop a gun and a grenade launcher to make up for the shortcomings of our factory!"
"The factory director is right!" As soon as Chen Zhen's voice fell, Qiao Junfeng took over with a smile: "Let's learn things and make our own, so as not to be controlled by others in the future!"
"That's right!" At this time, Wu Tianming also reacted: "Let's go to Director Zheng to introduce their machinery and equipment, learn their technology, don't let Director Zheng give us small fish, if you want to give us big fish!"
After Wu Tianming finished saying this, everyone present stared at each other, what a big fish and a small fish, they didn't understand what he meant by saying it, at this time, Yang Limin pushed the black frame eyes, looked at Wu Tianming, and asked tentatively:
"Representative Wu, do you want to say that it is better to give them fish than to teach them to fish!"
"Yes, yes!" Wu Tianming scratched his head awkwardly as he spoke: "Lao Yang is still educated, but it is better to give him a fish than to give him a fish!"
"You, you really should read more!" Chen Zhen, who understood the meaning, couldn't help but point at Wu Tianming and said with a smile, and then, bursts of laughter rang out in the room
