Siheyuan starts from a good life

As soon as he went to work, Jiang Yan started to get busy.

A complete set of automobile engines is divided into intake manifold, intake valve, piston, crankshaft, generator, tensioner pulley, crankshaft pulley, timing chain, throttle valve, spark plug, oil pan, connecting rod, and exhaust cam. There are thousands of parts to be manufactured, including shaft sprockets, exhaust camshafts, exhaust manifolds, and intake camshafts.

These parts, large and small, required Jiang Yan to draw a total of more than 80 drawings. Each drawing must be drawn in detail with specific dimensions and parameters, and some even indicate the manufacturing method and required materials.

For more precise gears, since there is no more precise lathe, only rough blanks can be produced, and the rest must be rolled manually.

When he came here today, Director Liu told himself that they had transferred a large number of fifth- and sixth-level workers from other factories, and several eighth-level workers had also been transferred. They fully obeyed Jiang Yan's arrangements.

If there are no difficulties in the production process, then the manufacturing is quite fast.

Since these drawings have been printed in Jiang Yan's mind, the drawing speed is quite fast, but it also took Jiang Yan almost a day to draw them all.

Looking at the drawings that had been drawn in his room, Jiang Yan stretched and moved his somewhat stiff neck. He directly picked up the phone on the table and called.

"Uncle Liu, I have drawn all the corresponding drawings. My opinion is to mobilize all eighth-level workers to make the mold first."

Generally, engine blocks are made of cast iron, because cast iron parts have good corrosion resistance and anti-rust capabilities, and also have good wear resistance. The cylinder block has good strength and has the advantages of being resistant to pressure and not easily deformed.

It mainly adopts one-time pouring molding, and the mold is particularly important. It is directly related to the success or failure of shaping the cylinder.

The engine block mold includes an upper template, a lower template and a positioning mechanism. These drawings were naturally drawn by Jiang Yan.

"I have no problem here. I will arrange the number of workers and materials needed. Let's meet in the first workshop."

Factory Director Liu hung up the phone immediately after saying this.

Jiang Yan looked at his watch and saw that there was still an hour left before getting off work. If he started processing now, it would obviously not be completed by the time he got off work. It seemed that he would have to work overtime tonight.

Jiang Yan took the drawings he had drawn and walked to the first workshop with Xu Damao.

Before the 20s, my country's industrial foundation was very weak, and most industrial products could not be produced by ourselves. Therefore, there were very few molds required, and there was no mold industry and mold technology. At that time, only a few companies could copy the few molds needed in the country, and they mainly relied on mold fitters to make some simple molds with their personal skills.

After the 50s, with the arrival of the climax of national economic construction, an increasing number of molds were needed for the production of various industrial products. At that time, the main processing was based on foreign mold patterns, and most of them were single-process molds, simple composite molds, progressive molds with few processes, and plastic compression molds that were demoulded outside the machine. With the development of international economic and technological cooperation and exchanges, foreign mold technology books, mold design manuals, mold manufacturing materials, etc. are gradually introduced to our country, playing an important role in guiding and promoting the development of mold technology.

At the same time, the introduction of some special processing equipment for manufacturing molds, such as large copy milling machines, coordinate boring machines and other equipment, has laid a certain material foundation for the manufacturing of large molds.

"Gong Jiang, let me introduce to you. These are the eighth-level workers I hired from other factories. This is Master Zhang Yong, the eighth-level fitter, Master Chen Lei, the eighth-level blacksmith, and Master Li Zhiwei, the eighth-level forger." Grade welder.”

Looking at these eighth-level masters, Jiang Yan was full of respect. These people were legendary for rubbing aircraft carriers with their bare hands. They were the masters of each type of work.

After introducing these eight-level masters, Director Li also introduced several other seventh-level and sixth-level masters.

Jiang Yan smiled and greeted these technical masters respectively.

Then Director Liu pointed at Jiang Yan and said, "Masters, this is Jiang Yan, Gong Jiang. Even though he is young, he is one of the first batch of SL students to study abroad after the founding of the country. He passed the SL exam while studying abroad. He has an engineer certificate and is currently the chief engineer of the third rolling mill. He was temporarily assigned by his superiors to assist us in the public relations of this car manufacturing. The entire car engine drawings were drawn by him."

Originally, these people were a little disapproving when they saw that Jiang Yan was relatively young. When Director Liu told him some basic information about Jiang Yan, their eyes were full of respect for him.

Anyone who is engaged in technology knows that there is still a big gap between the domestic technical level and foreign countries during this period. Therefore, the difficulty of obtaining an engineer certificate in China is much lower than that in foreign countries. Even so, only very few people can obtain an engineer certificate every year. , not to mention the engineer certificate of Big Brother SL.

Wait until Director Zhang introduces you to each other. Jiang Yan directly spread out the drawings, pointed at them and said, "Masters, these are the drawings of the mold. In the following time, Jiang Yan introduced the relevant parameters on his drawings in detail until all the masters had finished clear."

After understanding the parameters and requirements on the drawing, the older eighth-level fitter Zhang Yong said to Jiang Yan: "Jiang Jiang, there is no problem, just take a look!"

After hearing Zhang Yong's words, Jiang Yan directed Xu Damao to distribute the drawings to the corresponding personnel, while Jiang Yan and Director Zhang waited together until the parts were completed.

In order to produce the engine this time, Director Zhang specially vacated the first workshop. According to Jiang Yan's request, he also obtained a lot of equipment for making engines. In order to water the cylinder, he also specially built a small furnace.

The waiting time was extremely boring. Jiang Yan was also curious about the working status of the eighth-level workers, so he went to the lathe.

This expert knew whether it was there as soon as he made a move. Seeing Zhang Yong operating the machine tool to make the blank of the template, his movements were quite smooth, especially when he took out the knife and received it without any hesitation. He had everything in mind.

After watching Zhang Yong's operation, Jiang Yan walked towards the others to see how they operated. I have to say that this worker's craftsmanship is really good. In their hands, the parts were arranged one by one, and then they began to polish.

"Gong Jiang, it's ready over here." Hearing that someone had finished, Jiang Yan walked over with the measuring tool in his hand.

Jiang Yan took the tool and measured it. The parts made were exactly the same as the parameters in his drawings.

“Excellent product, the size is right, and the craftsmanship is good!”

Hearing Jiang Yan's praise, the fitter master was very happy. He scratched his head honestly and said, "Hey! We craftsmen don't rely entirely on our craftsmanship to make a living. This craftsmanship cannot be careless."

Then parts were manufactured one after another by the workers, and the manufactured parts were sent to Jiang Yan for testing.

This group of workers are all senior workers hired by Factory Director Liu. Their craftsmanship is truly unparalleled, and the parts produced are almost all high-quality.

Jiang Yan assembled the manufactured parts according to the drawings. After assembling, Jiang Yan measured it again. The product was still qualified, with almost no gaps.
