Chapter 135, Engine
After checking several times in a row, after confirming that there was no problem with the mold, Jiang Yan took the manufactured mold and went to the place where the sand mold was made together with Director Liu.
When Jiang Yan saw the pile of sand, he bent down and took the sand in his hand. The sand was very fine and felt good to the touch, especially when it was very dry.
These sands are natural quartz sand. Quartz has high refractoriness and hardness, and its excellent process performance can meet various basic requirements of foundry production. It can not only be used for traditional clay sand molding, but also resin sand and coating Membrane sand and other advanced molding and core-making processes, so quartz sand is widely used in foundry production.
The sand molds were made by two masters and apprentices, and these two masters and apprentices were workers from the auto parts factory, old craftsmen specially invited by Director Liu from other places.
According to Director Liu, the bronze wares molded by this master craftsman can be faked, and his adhesive also has this unique formula.
Under the skillful hands of the two masters, the sand mold of the cylinder of the automobile engine was quickly formed.
This sand model is so delicate that those who don't know it think it's a handicraft.
When the sand mold was formed, the molten iron in the steelmaking furnace also reached the appropriate temperature.
This molten iron is not ordinary molten iron but high-quality gray cast iron containing nickel, chromium, molybdenum, phosphorus and other elements.
The molten iron was poured into the sand mold, generating a large amount of mist.Now there is only waiting time left, and they need to wait for them to cool down slowly.
Jiang Yan was afraid of unexpected situations, so the workers made five molds in this series, and ten sand molds for this cylinder, and planned to produce ten cylinders at the same time.
After the workers made the molds, they began to make other parts of the engine according to the drawings.
The manufactured parts were also sent to Jiang Yan one after another.Jiang Yan conducted the final test.
The parts after the test were sorted and stored by Jiang Yan, and the final assembly was carried out after the cylinder was completed.
"Xiao Jiang, how's the situation?" Seeing Jiang Yan put down the last accessory, Director Zhang asked.
"All the parts are above good quality, Uncle Liu, the craftsmanship of this group of workers is really good."
Hearing Jiang Yan's introduction, Director Liu couldn't help complaining in his heart: "Can this be bad? Yishui's middle-level and above workers are almost the backbone of various factories."
"Xiao Jiang, can these equipment be manufactured with relatively low-level workers? You also know that this group of workers is almost the backbone I transferred from various factories. After the trial production is over, they will return to their respective factories. Let's Auto parts factories don’t have so many intermediate and high-level jobs.”
Hearing what Director Liu said, Jiang Yan pointed to the drawing and said with a smile: "Uncle Liu, you see, the most rare and important parts of this car engine are the cylinder, the piston and the crankshaft. The rest of the parts are basically There is no difficulty on the surface, and it can be made by low-level workers."
"But Uncle Liu, if you want me to say, let's just use these key things to manufacture by ourselves, and other not difficult and easy-to-manufacture parts are not only for low-level workers to practice. The rest will be distributed to other factories. Factories do the manufacturing, we do the standards and the procurement so we can scale up without having to hire as many workers and build as many factories."
"On the one hand, it can save some funds, and it can also help some factories appropriately. After all, the whole country is not a game of chess."
Jiang Yan's words made Director Liu fall into deep thought.
As an automobile manufacturing company, it is enough for manufacturing to grasp the key points.There is no need to pursue comprehensiveness.
In Jiang Yan's plan, the production of one car is enough to build a complete enterprise chain.
After pondering, Director Liu raised his head and said to Jiang Yan: "I can't decide this matter, but your idea is good. I need to report these ideas to the relevant leaders. Can these ideas be written into a related plan? Give me the book."
"No problem." Jiang Yan agreed quite readily.
The two stood there, chatting for a long time about car manufacturing.
At this time, the factory manager's secretary ran over and said to the two people who were chatting: "The factory manager, Jiang Gong, the worker in charge of cooling came over and told me that the cooling is almost done, and the molded parts can be taken out."
Hearing what the factory director's secretary said, the two stopped their conversation just now and walked together to the place where the cylinder was molded.
When he came to the place where the cylinder was molded, Jiang Yan took out a thermometer to measure the temperature. Seeing that the temperature had cooled to the predetermined temperature, he ordered the workers to lift the molded cylinder out of the sand mold.
Since there is no gantry crane, these shaped cylinders can only be lifted out manually.
Under the command of Jiang Yan, the cylinder that was lifted out cut out the redundant things that appeared on the cylinder during the shaping process, and used an air gun to blow away the sand and stones attached to the cylinder.
Then Jiang Yan directed the workers to carry out a second finishing process on the cylinder,
After finishing the cylinder block, the workers performed a series of operations such as polishing on them.
Then Jiang Yan began to assemble a series of moving parts such as crankshafts and connecting rods.
After these moving parts are installed, Jiang Yan is gluing the machine again. After these are completed, the cam is assembled. After these parts are installed, the engine of a car is basically completed.
After the basic assembly is completed, the engine has undergone external final assembly.
Only now has an engine been officially completed.
Then Jiang Yan assembled the other nine engines in the same way.
The scene of ten engines lined up was quite shocking.
Manufacturing an engine is not a simple matter. Any process determines the quality and performance of the engine. The process of each step is of high standards and strict requirements, and these processes are theoretically supported by thousands of scientific experiments.
Compared with the later V4, V6, and W8 cylinder engines, the inline 12-cylinder engine is much less difficult, but the manufacturing difficulty is still not easy.
This means that there are detailed drawings in Jiang Yan's space, and there are other installation techniques that have been thoroughly researched by later generations. Otherwise, this engine will not be researched in a few years.
"This is really made by us," Director Liu murmured to himself looking at the engine in front of him in disbelief.
Hearing Director Liu's words, Jiang Yan raised his head and glanced at the workers who were watching. These workers were as shocked as Director Liu.
"Uncle Liu, the facts are right in front of you, what's so unbelievable, don't you believe that your eyes are not." Jiang Yan said with a smile.
Hearing Jiang Yan's words, Director Liu came back to look at the row of engines in front of him, couldn't help but walked forward, gently stroked the engine with his hand, but said in his mouth.
"It's beautiful, it's so beautiful. I didn't expect us to make the engine in such a short time. I said that we can make what others can do. We Chinese don't discriminate against others."
Seeing Director Liu's current appearance, Jiang Yan's eyes couldn't help but ache.
