Siheyuan starts from a good life

"Leaders, I'm sorry I'm late." Jiang Yan first apologized to everyone after entering and sitting down.

"It's not too late. It's not time yet. Come to work and smoke." After the team leader, Director Xu, said this, he took out a pack of cigarettes from his pocket and threw it directly to Jiang Yan.

Jiang Yan picked up the cigarette thrown by Director Xu and took a look.

Let me go, "Big Production Cigarettes" are great stuff!

Dazhuang cigarettes are a cigarette produced by Shengjing Cigarette Factory. This cigarette was born with the founding of my heart, and with the growth and development of the People's Republic of China. In the 50s, demand for large-scale cigarettes was in short supply. Even leaders could only have one pack a month. Moreover, large-scale cigarettes were sent to the front lines as condolences. It can be said that they were welcomed by many soldiers.

After taking a look at the cigarette, Jiang Yan looked up and saw Director Xu's meaningful smile. After thinking about it, he put the box of cigarettes directly into his pocket.

I randomly picked up the "National Defense Brand" cigarette on the table and took a puff.

People coming to the meeting came one after another, and soon the conference room was filled with people.

"Mr. Jiang, how is the construction of the automobile production line going? Please introduce it to everyone."

Factory Manager Liu, who was sitting above, asked without any nonsense and went straight to the point.

After hearing what Director Liu said, Jiang Yan opened his notebook and took a look, and then said: "This automobile production line was designed and produced by me and a group of professors from Tsinghua University by referring to foreign automobile production lines and combining it with our country's conditions. production line."

"Due to the lack of relevant equipment, there is a certain gap between this production line and similar foreign production lines. At full capacity, the annual output of this production line can only produce more than 10,000 cars."

Similar foreign production lines consist of four parts: stamping, welding, painting and powertrain!

Our country's stamping equipment is limited, and most of the parts are produced by various factories, so the stamping is removed, and only the three parts of welding, painting and powertrain are retained. At present, the entire production line has been fully debugged and can be used at any time. put into production use.

"The parts allocated to major factories are now in place, and all parts have been inspected and are fully qualified."

"How many cars can be assembled from the parts that are delivered."

Factory Director Liu then asked.

"A total of ten cars and ten jeeps can be produced."

"Okay, Worker Jiang did a good job." After hearing Jiang Yan's report, Director Liu happily praised him.

"How is the situation of the workers arranged?" After praising Jiang Yan, Director Liu asked Deputy Director Feng who was sitting under him.

"All workers are already in place. These workers have received assault training and are fully qualified."

"Okay," after Director Liu said this, he turned to Director Xu, who was leading the military team, and said, "Director Xu, do you have any problems here?"

Director Xu nodded after listening to Factory Director Liu's words, and then said: "Is there any difference between the production line of this car and the jeep production line we requested? Can you produce a separate production line for us?"

"no problem."

Jiang Yan had considered this issue when he originally designed this production line. A little modification will do the trick.

Moreover, the difference between military jeeps and civilian versions of jeeps is huge.

For a military jeep, you only need to consider that the vehicle has reliable performance, a simple structure, is common with the main components of the vehicle, is easy to maintain, and is resistant to grass.

As for the comfort type, ignore it completely.

The military jeep designed by Jiang Yan is almost completely based on the design concept of the Willys Jeep of Citigroup during World War II.

Compared with Citi's Willys Jeep, the Jeep designed by Jiang Yan is more powerful and larger.

The first consideration for civilian jeeps is comfort, and Jiang Yan also incorporated the concept of later generations of SUVs into it.

This was the shortest meeting Jiang Yan had ever held in the conference room, and it ended in less than twenty minutes.

After the meeting, everyone walked together to the workshop where the car production line was installed. Getting ready to start producing cars.

When everyone arrived at the workshop, the workers were already waiting there, just waiting for Jiang Yan's order to start production.

After Jiang Yan signaled to the two leaders, he shouted loudly,

"Start"

As soon as Jiang Yan finished speaking, the workers pushed a series of parts on the side and roof of the previously produced car to the welding station.

At this time, several welding masters took welding torches and began to weld these parts.

Common welding methods include fusion welding, pressure welding and brazing. In order to improve efficiency, the production line only uses fusion welding.

The main welded assemblies of the entire car include: engine compartment assembly, floor assembly, side panel assembly, door cover assembly and other parts. After all these are welded, the rough prototype of a car appears in front of everyone.

The welded car body will be inspected by experienced master craftsmen, and if there are any omissions, they will be re-welded again.

After the inspection, there is no problem, and then the car body enters the next process.

At this time, Jiang Yan led a group of leaders to visit the workshop. While visiting Jiang Yan, he also explained it.

“This shop is a welding shop, where all the car bodies are done.”

The visitors nodded when they heard Jiang Yan's words, and some leaders were curious to observe the workers' welding work at close range.

After about half an hour, the body of a car, the body of a civilian jeep and the body of a military jeep have been welded.

Jiang Yan led the leaders to the three completed welded bodies and introduced: "Military jeep must consider bulletproof, its body is thicker than civilian body."

After Jiang Yan said this, he made way for the leader to visit.

After the leaders finished their visit, Jiang Yan directed the workers to push the three car bodies together to the next workshop.

"This workshop is a painting workshop. The painting workshop mainly goes through three processes: electrophoresis, intermediate paint, and topcoat. Before electrophoresis, impurity cleaning, oil stain cleaning, phosphating treatment, etc. need to be carried out. The main function of electrophoresis is to prevent corrosion of the body in white. , after electrophoresis, it is dried and entered into the next process."

Jiang Yan said as he led the man inside.

At this time, the workers in the workshop were ready. After seeing the three frames coming in, they started to get busy according to the previous drill.

After being cleaned again, the car body emits a silver-white metallic light.

Workers pushed the cleaned frame into a pool of white paint.

At this time, Jiang Yan pointed at the pool and introduced: "This pool is filled with prepared white paint. Its function is to provide anti-corrosion treatment for the car body."

While Jiang Yan was talking, the car body that had been soaked in anti-corrosion paint was fished out of the pool by workers and placed in a room similar to a container.

"This is a drying machine. The frame coated with anti-corrosion paint is dried here."

Jiang Yan didn't say anything after the introduction, but quietly waited for the three car frames to dry.

This process does not take long, only about ten minutes. After opening the drying box, the workers use hooks to pull out the dried frame for the next step of the painting process.

A car needs to be painted three times. After three times of painting, a black frame and two military green frames appeared in front of everyone.
