Siheyuan starts from a good life

After checking several times to make sure 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 with Director Liu.

When Jiang Yan saw the pile of sand, he leaned down and took the sand in his hand. The sand was very fine and felt good to the touch, especially it was extremely dry.

These sands are natural quartz sand. Quartz has high fire resistance and hardness, and its excellent process performance can meet various basic requirements of casting production. It can not only be used for traditional clay sand modeling, but also for resin sand and coating. Coated sand and other advanced molding and core-making processes, so quartz sand is widely used in foundry production.

There were two masters and apprentices who made the sand molds. These two masters and apprentices, together with the workers of the auto parts factory, were experienced craftsmen specially invited from other places by Director Liu.

According to Factory Director Liu, the bronzes made by this master can be fake and real, 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 mold is so exquisitely made that those who didn’t know better thought it was a handicraft.

When the sand mold is being formed, the molten iron in the steel-making furnace reaches the appropriate temperature.

This molten iron is not ordinary molten iron, but high-quality gray cast iron containing elements such as nickel, chromium, molybdenum, and phosphorus.

The molten iron was poured into the sand mold, creating a large mist. Now there is only time to wait for them to slowly cool down.

Jiang Yan was afraid that something unexpected would happen, so he asked the workers to make five molds. Ten sand molds for the cylinder were also made, preparing to produce ten cylinders at the same time.

After the workers made the mold, they started making 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 that had been tested were sorted and stored by Jiang Yan, and the final assembly was carried out after the cylinder was completed.

"Xiao Jiang, how is the situation?" Director Zhang asked when Jiang Yan put down the last accessory.

"All the parts are of higher quality, Uncle Liu, the craftsmanship of these workers is really good."

After hearing Jiang Yan's introduction, Director Liu couldn't help but complain in his heart: "Can this be bad? Yishui's mid-level and above workers, these workers are almost the backbone of each factory."

"Xiao Jiang, can these equipment be manufactured with lower-level workers? You also know that this group of workers are almost all the backbones I transferred from various factories. After the trial production is completed, they will return to their respective factories. Let's Auto parts factories don’t have so many mid- to high-level jobs.”

Jiang Yan heard what Director Liu said, pointed at the drawing and said with a smile: "Uncle Liu, look, the most rare and important parts of this car engine are the cylinder, piston and crankshaft. The rest of the parts are basically There is nothing difficult about it, and it can be made by low-level workers.”

"But Uncle Liu, if you ask me, let's just make these key things ourselves. Other parts that are not difficult and easy to make will be given to low-level workers to practice. The rest can be distributed to other factories. From these The factory is responsible for manufacturing, and we are responsible for setting standards and purchasing, so that we can expand production without hiring so many workers and manufacturing so many factories."

"On the one hand, this can save some funds, and on the other hand, it can also help some factories appropriately. After all, the whole country is not a chess game."

Jiang Yan's words made Director Liu fall into deep thought.

As an automobile manufacturing company, manufacturing can only 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 make the decision on this matter, but your idea is good. I need to report these ideas to the relevant leaders. Can these ideas be written into a relevant plan? Give me the book."

"No problem." Jiang Yan agreed readily.

The two people just stood there and chatted for a long time about car manufacturing.

At this time, the secretary of the factory director ran over and said to the two people who were chatting: "Factory director, Worker Jiang, the worker who was responsible for cooling just now came over and told me that it has almost cooled down and the molded parts can be taken out."

After hearing the words of the factory director's secretary, the two of them stopped their conversation and walked together to the place where the cylinder body was molded.

When he came to the place where the cylinder was being shaped, Jiang Yan took out a thermometer to measure the temperature. When he saw that the temperature had cooled to the predetermined temperature, he directed the workers to lift the shaped 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 lifted cylinder was cut out of the excess that appeared on the cylinder during the shaping process, and the sand and gravel attached to the cylinder were blown away with an air gun.

Then Jiang Yan directed the workers to perform a second finishing process on the cylinder body.

After finishing the cylinder block, workers performed a series of operations such as polishing.

Then Jiang Yan began to assemble a series of moving parts such as the crankshaft and connecting rods.

After installing these moving parts, Jiang Yan glued the machine. After these were completed, he assembled the cam. After all these parts were installed, a car engine was basically completed.

After the assembly was basically completed, the engine underwent external final assembly.

Only now has an engine been officially completed.

Then Jiang Yan assembled the other nine engines in the same way.

Ten engines lined up in a row, the scene was quite shocking.

Manufacturing an engine is not a simple matter. Every process determines the quality and performance of the engine. Each step of the process 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 difficulty of the inline 12-cylinder engine has been reduced a lot, but the manufacturing difficulty is still not easy.

This means that there are detailed drawings in Jiang Yan's space, as well as installation techniques that have been thoroughly studied by later generations. Otherwise, this engine would not be researched at all in just a few years.

"This is really made by us," Director Liu muttered to himself as he looked at the engine in front of him with some disbelief.

After hearing Factory Director Liu's words, Jiang Yan raised his head and glanced at the workers who were watching. These workers were just as shocked as Factory Director Liu.

"Uncle Liu, the facts are right in front of you. What's so incredible about it? Don't you still believe your own eyes?" Jiang Yan said with a smile.

Hearing Jiang Yan's words, Director Liu came back to his senses and looked at the row of engines in front of him. He couldn't help but walk forward and gently stroked the engine with his hand while speaking.

"Beautiful, so beautiful. I didn't expect that we could make the engine in such a short time. I said that we can make what others can do. We Chinese people don't make any distinction between others."

Looking at Factory Director Liu's current appearance, Jiang Yan's eyes couldn't help but feel sour.
