Siheyuan starts from a better life

Chapter 134, Mold

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

A complete set of car engine, divided into intake manifold, intake valve, piston, crankshaft, generator, tensioner pulley, crankshaft pulley, timing chain, throttle valve, spark plug, oil pan, connecting rod, exhaust cam Shaft sprockets, exhaust camshafts, exhaust manifolds and intake camshafts, etc., there are thousands of parts to be manufactured.

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

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

When I came here today, Factory Manager Liu told himself that they had transferred a large number of fifth- and sixth-level workers from other factories, and a few eighth-level workers.They followed Jiang Yan's arrangement with all their might.

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

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

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

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

Generally, engine cylinder blocks are made of cast iron, because cast iron parts have good corrosion resistance and rust resistance, as well as good wear resistance, good cylinder block strength, and the advantages of compression resistance and deformation resistance.

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

The engine block mold includes several aspects such as 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 how many workers and materials are needed. Let's meet in the first workshop."

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

Jiang Yan looked at his watch, and there was still an hour before he got off work. If he started processing now, it would be impossible to finish it when he got off work. It seems that he will have to work overtime tonight.

Jiang Yan took Xu Damao with the blueprints he had drawn to the first workshop.

Before the 20s, my country's industrial base was very weak, and most industrial products could not be produced by itself, so there were very few molds needed, and there was no mold industry and mold technology.At that time, only a few enterprises could imitate the few molds that were needed in China, and they mainly relied on mold fitters to manufacture some simple molds with their personal skills.

After the 50s, with the arrival of the climax of national economic construction, the molds required for the production of various industrial products are increasing.At that time, it mainly stayed in processing with reference to foreign mold drawings, and most of them were single-process molds, simple composite molds, progressive dies with few processes, and plastic compression molds for external demoulding.With the development of international economic and technological cooperation and exchanges, foreign mold technology books, mold design manuals, mold manufacturing materials, etc. have gradually been introduced to our country, which has played 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-scale copying milling machines and coordinate boring machines, has laid a certain material foundation for manufacturing large-scale molds.

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

Looking at these eighth-level masters, Jiang Yan was full of respect. These people are the legendary existence of rubbing aircraft carriers with bare hands. In each of their jobs, they are a generation of masters.

After introducing the masters of these eighth-level workers, the factory director introduced several other seven-level and sixth-level masters.

Jiang Yan smiled and greeted these technical masters respectively.

Then Director Liu pointed to Jiang Yan and said: "Masters, this is Jiang Yan, Jiang Gong, don't look at his young age, he is the first batch of SL students to study abroad after the founding of the country. The engineer certificate of the third rolling mill, who is currently the chief engineer of the third rolling mill, was temporarily transferred by the superior to assist us in the public relations of this car manufacturing. The drawings of the entire car engine were drawn by him."

Originally, these people were a little disapproving when they saw Jiang Yan's relatively young age. When they heard some basic information about Jiang Yan from Director Liu, their eyes were full of respect for him.

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

Wait until Director Zhang introduces you to everyone.Jiang Yan spread out the drawings directly, pointed to the drawings and said: "Masters, these are the drawings of the mold. In the next time, Jiang Yan introduced the relevant parameters on his drawings in detail, until all the masters made the drawings. clear."

After figuring out the parameters and requirements on the drawings, the older eighth-level fitter Zhang Yong said to Jiang Yan: "Jiang Gong, there is no problem, just look at it!"

Hearing Zhang Yong's words, Jiang Yan directed Xu Damao to distribute the drawings to the corresponding personnel, while Jiang Yan and Zhang Zhang waited for the parts to be completed.

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

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

This expert knows if there is one as soon as he makes a move. Watching Zhang Yong operate the machine tool to make the blanks of the template, the movements are quite silky, especially when the knife is delivered and received, without the slightest hesitation, he knows everything about it.

After watching Zhang Yong's operation, Jiang Yan went to other people to see how they operated. I have to say that this worker's craftsmanship is really good.In their hands, the parts are lined up one by one, and then they start to polish.

"Jiang Gong, this side is ready." 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 that were made were exactly the same as the parameters of his drawings.

"Excellent quality, qualified size, good workmanship!"

Hearing Jiang Yan's praise, the master fitter was quite happy, scratched his head honestly and said, "Hey! We craftsmen don't rely on craftsmanship for our food, and the craftsmanship of eating can't be sloppy."

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

All these workers are senior workers recruited by Factory Manager Liu. There is no such thing as such craftsmanship. Almost all the parts produced are high-quality goods.

Jiang Yan assembled the manufactured parts according to the drawings. After assembling, Jiang Yan re-measured, and the product was still qualified, with almost no gaps.
