Chapter 226: Assembly Line
Before World War II, Japan had to import a large amount of scrap steel from the United States and other European and American countries every year to make steel in its own steelworks, and the quality of the steel was no worse than that of steel made without pig iron.
Xiao Zhenlei kept this matter in mind, and prepared to make the next plan on the facts, he took the new gun and looked at it again, and Robert, the chief engineer of the firearms factory opposite, asked: "Mr. President, this new rifle has no name yet, you better give it a name, otherwise we don't know what to call it!" ”
Xiao Zhenlei thought for a while and said: "Let's call it zh-1909, zh means our Zhenhua company, and it can also mean China, and this rifle was designed and manufactured this year!" ”
Robert shrugged his shoulders in understanding, "OK, it's called zh-1909."
Xiao Zhenlei asked, "After this gun was built, did you find someone to test it?" ”
"Of course, we found more than a dozen soldiers in the escort team, took turns to use the same gun, and fired continuously for two days and two nights without stopping, and a gun will be scrapped = if it fires more than 1,500 times, but its accuracy is very good, and in addition to the dud, there is basically no jam, if it is not limited by the quality of the material, I believe its performance will be better!" Robert describes the actual situation of this gun.
In fact, Xiao Zhenlei also knew that this rifle might work well in this environment. But maybe if you change the environment, there will be some problems with its performance. For example, it is used in the desert, and then it is used in the ice and snow. It is possible to have a bad impact on this rifle, but as long as it can fire normally, it will not be a big problem if it does not occur frequently, if it changes the environment, it will mean that the gun is not good, think about it, if the gun suddenly jams in a very dangerous battle, isn't this a fatal thing? But in reality? There is no rifle in the world that is without flaws, and it will be more or less affected by the environment, so it is said that the standard rifle M-16 of the US military in later generations is often easy to jam when used in the desert. The reason is that sand easily gets into the barrel and affects firing.
"Fifteen hundred? It's a little less fired than other rifles, but it's enough for now! Xiao Zhenlei said, thought for a while and asked, "Like this rifle, how many can the arsenal produce per day?" ”
"Due to the technical proficiency of the workers, I have calculated that we can only produce a maximum of 50 rifles per day on average, because we only have so many skilled workers for the time being, and it takes about three to four days for each skilled worker to produce a rifle, which is an average of 50 per day," Robert said.
Xiao Zhenlei couldn't help frowning when he heard this. "How can the production efficiency be so low when we have such a large arsenal, complete tools and equipment, and sufficient materials?"
Robert spread his hands and shrugged: "No way. The workers are not skilled enough, you think, just remove some iron spikes or iron filings from the rifling of the barrel. It is not easy to make the grooves of the rifling inside the barrel clean, and the part of the butt needs to be painted. The metal parts need to be sanded and polished, which is very time-consuming. There are also rifles that are no more expensive than pistols, and the assembly of rifles is much more troublesome than pistols, and it is time-consuming to polish and polish every part before assembly! ”
Xiao Zhenlei remembered the assembly line, under the condition that the tools and production machines are well equipped, the design of an assembly line production line will undoubtedly improve the production efficiency a lot, as long as the design is good, save unnecessary wasted time, it is very possible to increase the production efficiency several times, and according to the current manufacturing process, almost every worker has taken care of all the processes of manufacturing rifles, no wonder Robert said that it takes three to four days for a worker to make a rifle, how can this work, Not every worker is such an all-powerful master.
After thinking about it for a while, Xiao Zhenlei said: "Mr. Robert, you see if this will work, we design an assembly line production line, we will split all the production steps and processes for the production of a rifle, and then let a few of the workers be responsible for one of the production steps and processes, that is to say, each of them only needs to do one process, and then assemble when all the parts and components are completed, and we can use a power conveyor belt to connect the various production steps and production processes. When a worker completes the process of this part, the part is placed on the conveyor belt, and the conveyor belt will automatically transfer the part to the next process by another worker for the next process, so that each worker only needs to be responsible for one process, he will soon become a skilled worker, which can also greatly save time and improve production efficiency! ”
Robert listened to Xiao Zhenlei's words, the more he thought about it, the brighter his eyes became, and when he felt that this mention was completely feasible and could greatly improve production efficiency, he hugged Xiao Zhenlei and kissed him fiercely, "Oh, dear Xiao, you are so great, this method can be thought of, if I am not miscalculated, according to what you said to design such a production line, our production efficiency will be increased several times, by the way, do you have any suggestions for this aspect?" Since you have come up with this method of assembly line line, I think you must have thought about the characteristics and requirements of it, right? ”
Xiao Zhenlei nodded and thought for a while and said: "The design of the production line involves the calculation of a variety of numbers, and we must strive to be accurate in the calculation, and there is a correlation between these numbers. If the connection is not clear, the rhythm will be chaotic and uncoordinated during the assembly line operation. Therefore, when designing the assembly line, it is necessary to calculate the indicators scientifically and reasonably, and arrange the assembly line reasonably.
First of all, we need to clarify the type of assembly line, according to my understanding, the assembly line can be divided into a single object pipeline and a multi-object pipeline according to the number of production objects. The assembly line of a single object is to produce only one product in a fixed manner, and the variety is single. It is a mass production type. The multi-object assembly line refers to the production of two or more products, which can also be further divided into: variable assembly line. It is a fixed batch production of several products in turn. Mixing pipeline. Several products are produced at the same time for a certain period of time. When changing varieties, there is basically no need to adjust equipment and process equipment.
According to the continuous process of the production process, it is divided into: continuous assembly line. It means that the processing of production and processing objects on the assembly line is carried out continuously, without waiting for stoppage. It is suitable for mass production and is an ideal assembly line form. The intermittent assembly line refers to the phenomenon that the production object will stop and wait and time interruption between the processes due to the unequal or integer times of each process on the assembly line, and the unbalanced production capacity.
According to the mode of product transportation, it can be divided into: no special transportation equipment assembly line. The assembly line operator directly uses ordinary transportation equipment to transfer the product to the next process by hand. There is a special transportation equipment assembly line. Special transport equipment is used to transport products between processes.
In the design, we need to carry out technical design and organizational design, and technical design includes the formulation of process routes and process specifications. Design of special equipment, modification of equipment, design of tooling fixtures, design of transportation and conveying devices, etc. The organizational design includes rhythm, beat, number of assembly line equipment, load factor of equipment, number of people and conveying speed. After the design is completed, we also have to lay out it, plan layout, point and line layout, etc.! ”
When Xiao Zhenlei finished speaking, Robert was holding a small notebook and recording what he just said with a pen, and he smiled: "You don't have to remember, just know it in your heart." In fact, the assembly line is not a new thing, the Ford Motor Company in the United States and our Zhenhua company's automobile manufacturing plants have begun to adopt this assembly line production mode on a large scale, a production unit of the process of thousands of kinds, this has to go through repeated practice and calculation to determine the number of workers required on a production line and the distance between each process."
Although Xiao Zhenlei said so. But Robert still wrote it down patiently with a pen, and when he was done, he patted his chest and promised: "Mr. President, rest assured, I will definitely design and produce the best assembly line for our gun factory!" ”
"Then please. I'll reward you when you've designed it and got the line to work! Xiao Zhenlei patted him on the shoulder. And he said, "By the way, I think you can also design a bullet assembly line." The speed of our production of bullets is too slow, and the warhead of each bullet still needs to be grinded by workers, which is too time-consuming and laborious, and the quality of the bullet cannot be guaranteed. ”
Robert hurriedly agreed: "Okay, okay, I will definitely satisfy you, and when I succeed, you can't be stingy with the reward I deserve!" ”
Xiao Zhenlei smiled: "Of course, my words count!" After speaking, he took the briefcase from Opiyin's hand and took out a stack of drawings and said: "This is a pistol designed by me, which is an automatic pistol like the Mauser military pistol, you can see if it can be produced!" ”
This is Xiao Zhenlei's shooting drawings drawn according to the appearance of the Browning 1911 pistol in his memory, and he remembers the specific performance parameters of this pistol and the size of each part very clearly, so it took no effort to draw it.
Robert took it and looked at it, nodded and said, "Okay, I'll take this seriously!" ”
After leaving the gun production factory, Xiao Zhenlei came to the artillery production factory again, before he had handed over a mortar design drawing to the chief engineer of the artillery factory, the American McConaughey, Robert and McConaughey were both fooled by Fast from the two arsenals in the United States, and Xiao Zhenlei gave them a salary that was not low, at least twice their salary in the United States, and there was a year-end bonus at the end of the year.
Mr. McConaughey was leading a group of Chinese workers and apprentices around a freshly built mortar, made exactly from Xiao Zhenlei's shot, except that the barrel and exterior parts of the mortar had not yet been painted with anti-rust paint.
"How? Let me see! Xiao Zhenlei squeezed over, picked up a few workers, and walked into the crowd.
"Oh, that's beautiful!" Xiao Zhenlei looked at the mortar with a metallic sheen.
When McConaughey heard Xiao Zhenlei's praise, he immediately felt a little proud, and said with a smile: "Of course, the artillery made by me and the apprentices I brought out can definitely be called a work of art, although its steel quality can't fire too many shells, but it is absolutely fine with two or three years, and when you solve the problem of steel quality in the future, these small artillery pieces can also be eliminated!" ”
Xiao Zhenlei asked, "Have you tried it?" ”
"Not yet!" McConaughey shook his head, "It's just been assembled, but according to the shell drawings you provided, we've already produced more than a hundred and twenty shells."
"Then let's go to the convoy's camp training ground and try to shoot a few shots?" Xiao Zhenlei said.
"Of course, I'm more than happy to!" McConaughey immediately agreed, so Xiao Zhenlei called a few skilled workers to carry mortars, and carried a few boxes of guns out of the artillery production plant, Xiao Zhenlei and McConaughey took a car, and several other workers drove in a large truck under the protection of the factory guards in the direction of the escort team's training camp.
This kind of big truck is made by automobile manufacturers, in fact, more than ten or twenty years ago, Germany made trucks, the emergence of trucks is not a new thing, just because the problem of car engine horsepower has not been applied on a large scale.
Soon, Xiao Zhenlei and others drove into the shooting range, the shooting range is backed by a hill, this hill has been dug up in half, the stone is used to build the factory and foundation of Zhenhua Company and the workers' dormitory, the remaining half of the mountain is used as the escort shooting range, when the target will shoot the warhead to the cliff of the mountain, will not hit other irrelevant people, Xiao Zhenlei is ready to use this hill as a mortar site.
Ma Hanlong also rushed over with some guards when he got the news, on the one hand, to guard the surroundings to prevent leaks, and on the other hand, to see if there was anything that needed help.
Xiao Zhenlei beckoned a few guards to come over and let them follow him to learn how to operate this mortar, which was a light mortar of 60 mm caliber.
"You see that this small artillery is very simple to operate, the trajectory is curved, and it can be fired close to the target, and there is almost no dead angle for shooting; After the shell is loaded from the muzzle, it is forced to fire by relying on its own deterioration in mass, so that the shell is fired. Moreover, this kind of artillery is easy to carry, and can provide artillery support for infantry attacks, especially mountain warfare and trench warfare, and cooperate with small infantry units (such as companies, platoons, and squads) to fight, and is the standard fire support weapon for infantry. Ideal for targets behind shelter. Here is to adjust the muzzle elevation angle, this is the gun body, this is the gun carriage, this is the seat plate, this is the sight, this gun is composed of these four parts, come, let's shoot a shot!
