"Master Hua, I have something to bother you. Looking back, there is a drawing of a new product, you have to help me. I am alone, I am afraid I can't do it." Zhao Guoyang said sincerely to Hua Guosheng.

"This is fine. I can still draw ordinary workwear drawings. However, if it is too complicated..." Hua Guosheng rubbed his hands and said crampedly.

"Don't worry, Master Hua, I'll draw it myself if it's too complicated!" Zhao Guoyang quickly gave Hua Guosheng a reassurance.

After the morning meeting, Zhao Guoyang and a group of people from the technical department returned to the office.

After taking the Hongta Mountain scattered in Zhao Guoyang, everyone naturally congratulated for a while. After chatting for a while, everyone went to their own business.

Seeing that only Hua Guosheng was left in the office, Zhao Guoyang picked a few from a stack of drawings and walked to his seat and said, "Master Hua, you can take a look at these parts drawings first. If there is no problem, please help me draw the workwear drawings."

"Ah, are there no real objects?" Hua Guosheng was a little surprised after taking these pictures.

Hearing this, Zhao Guoyang shook his head and smiled: "There is no physical object. This frame is a new product of Siyang Group. Another machinery factory Shunxin has only produced one trial frame for them. It is definitely impossible to disassemble it and bring it back to me... So, we can only rely on ourselves."

Upon hearing this, Hua Guosheng looked embarrassed on his face.

Indeed, in this era, if there is no physical object to design workwear drawings, it is not very difficult.

Because it is difficult for ordinary technicians to imagine the specific appearance of a part from a two-dimensional diagram. Only by using the real objects and combining with the two-dimensional diagram can they know what a part will look like after it is formed.

Of course, some clues can be seen through two-dimensional diagrams for some simple parts.

In contrast, Zhao Guoyang seems extremely alternative.

Although computers have not yet been popular in this era, and there are no three-dimensional software such as PRO-E and UG, as long as he takes a look at the two-dimensional diagram of the parts, basically, the three-dimensional image is already displayed in his mind.

Only top engineers who have drawn thousands of parts drawings and contacted with various types of mechanical parts can have such skills.

There is no doubt that Zhao Guoyang must have such ability as a senior engineer who enjoyed special allowances from the State Council in his previous life.

"It's okay, Master Hua. You can look at the two-dimensional picture first. If you can't figure it out, put it there first. If I have time, I will draw a rough look for these parts. With this, you should be able to draw a workwear picture." Zhao Guoyang comforted.

"Okay, if you can really draw the parts in Guoyang, I guarantee that you can complete the task!" Hua Guosheng picked up the drawings and nodded vigorously.

With Hua Guosheng's promise, Zhao Guoyang finally breathed a sigh of relief. In fact, drawing a simple three-dimensional picture was a necessary link for him.

After the new frame is designed, he will definitely use three-dimensional drawings with good results to communicate with production. Otherwise, the workers in the workshop will not be able to make it according to the two-dimensional drawings.

After explaining a few words to Hua Guosheng, Zhao Guoyang began to study the frame diagram given to him by Siyang Group one by one.

There was nothing special about the overall picture. After just a few glances, Zhao Guoyang knew how to dissect the frame.

After reading the general picture, it is the part picture.

The reason why the curved beam frame is difficult to manufacture is mainly because of its backbone.

For general motorcycles, such as straddle or pedal type, their frames are basically composed of large and small steel pipes, bent and combined.

The frame of the curved beam is somewhat different. The main part of the frame is made of steel pipe and steel plate splicing. Therefore, this type of frame is also called steel pipe and steel plate hybrid spine frame abroad.

As we all know in the industry, the gap between the steel pipe and the steel plate is very large. If you want to splice it together, strength will become a very important issue.

In addition, the bend of the steel pipe on the frame of the bend beam car is much larger than that of the ordinary frame.

If you want to form steel pipes, you need a better pipe bending machine. With the current level of pipe bending machine in Hongda Machinery Factory, it is indeed quite difficult to make the main beam of the bent beam frame of the car.

After looking at the parts diagram for a while, Zhao Guoyang discovered a bent pipe at the backbone of the frame, and the connection between the bent pipe and the steel plate below, which is a difficulty in the entire frame.

"Well, this problem seems to be a bit troublesome for a while. The bent pipe is too large and can be solved. If it is really not possible to splice it with a square pipe. However, the welding strength between the bent pipe and the flat plate is a big problem." Zhao Guoyang thought secretly.

The backbone of the bent beam frame is the driver's seat, so the force it bears is relatively large.

If the welding is not firm enough, it is easy to cause safety problems. Zhao Guoyang knows this very well.

In this era, laser welding is far from popular, and Zhao Guoyang is also a clever man who can cook without rice. If there is a laser welding machine, the problem will be much easier to solve.

Just as Zhao Guoyang passed the drawings one by one, Xu Dongfeng's voice suddenly came from outside.

"Lao Hua, Lao Hua, something happened. The inspection station found out that the iron oil tank manufactured by our factory for the Mingke Tractor Factory leaked oil." Xu Dongfeng came in panting and shouted.

"What? Oil leaks in the fuel tank?" Hua Guosheng was shocked when he heard this.

Mingke Tractor Factory is an old customer of Hongda Machinery Factory. The production volume of this factory has always been relatively stable. Although it is not large, it has never stopped.

Basically, it looks like twenty or thirty fuel tanks per month.

A few days ago, a large order came from the Mingke Tractor Factory. A middleman from the western provinces asked them to order 120 tractors at once.

One hundred and twenty tractors means one hundred and twenty fuel tanks. This is a big deal for Hongda Machinery Factory.

So Wang Youchang immediately assigned a task to the technical department, asking Hua Guosheng, an old technician, to be responsible for the production tasks of this batch of fuel tanks.

Zhao Guoyang heard Xu Dongfeng talk about this yesterday. He is Hua Guosheng's apprentice, so he naturally has to follow Hua Guosheng to fight.

After several days of busy life, most of the fuel tanks have been completed, and today it should be over. Who knew that there was a sudden oil leakage and that Hua Guosheng was particularly nervous, so it was understandable.

Just when Zhao Guoyang was stunned, Hua Guosheng had already stood up and hurried to the door. While running, he asked Xu Dongfeng: "Xiao Xu, are there many oil tanks that leak oil? How many are there in total?"

"I just checked ten, only three of them are good." Xu Dongfeng replied.
