"That's no problem, I can still draw general tooling drawings.
However, it's too complicated," Hua Guosheng rubbed his hands and said a little crampedly.
"Don't worry, Master Hua, it's too complicated, I'll draw it myself" Zhao Guoyang hurriedly gave Hua Guosheng a reassurance.
After the morning meeting, Zhao Guoyang returned to the office with a group of people from the technical department.
After taking over Zhao Guoyang's scattered Hongta Mountain, everyone was naturally lively and happy for a while, chatting for a while, and everyone went to their own places.
Seeing that only Hua Guosheng was left in the office, Zhao Guoyang picked a few from a stack of drawings, walked to his seat and said, "Master Hua, you can take a look at these parts drawings first."
If there are no problems, help me draw the tooling drawing. ” "Ah, don't you have a physical object" After taking these pictures, Hua Guosheng was a little surprised.
Hearing this, Zhao Guoyang shook his head and said with a smile: "There is no physical object, this frame is a new product of Siyang Group, and another machinery factory, Shunxin, has only produced a trial frame for them, and it is definitely impossible to disassemble it and bring it back to me, so we can only rely on ourselves." ” When Hua Guosheng heard this, his face showed a touch of embarrassment.
Indeed, in this era, if you don't want to design tooling drawings in kind, the difficulty is not ordinary.
Because it is difficult for the average technician to imagine the specific appearance of a part from a two-dimensional drawing.
Only with the help of the real thing, with the two-dimensional drawing, can we know what a part looks like after molding.
Of course, some simple parts can still be seen through two-dimensional diagrams.
In contrast, Zhao Guoyang is extremely unusual.
Although computers were not yet widespread in this era, and there were no three-dimensional software such as ROE and UG, he only needed to look at the two-dimensional diagram of the part, and basically, the three-dimensional image was already displayed in his mind.
This kind of ability can only be possessed by top engineers who have drawn thousands of parts and worked with various types of mechanical parts.
There is no doubt that in his previous life, as a senior engineer who enjoyed the special allowance of the State Council, Zhao Guoyang must have such ability.
"It's okay, Master Hua.
You look at the two-dimensional diagram first, and if you can't figure it out, put it there first.
If I have time, I'll give you a rough picture of the parts.
With that, you should be able to draw your tooling.
Zhao Guoyang said with relief.
"Okay, if Guoyang you can really draw the general appearance of the parts, 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 simple three-dimensional drawings is a necessary part for him.
After the new frame is designed, he must take the three-dimensional drawing with the good effect to communicate with the production, otherwise, the workers in the workshop will not be able to make it at all according to the two-dimensional drawing.
After explaining a few words to Hua Guosheng, Zhao Guoyang began to study the frame diagram handed over to him by Siyang Group one by one.
On the general map, there is nothing special, only a few glances, Zhao Guoyang knows how to dissect this frame.
After reading the general drawing, it is the parts drawing.
The reason why the frame of the curved beam car is difficult to manufacture is mainly its backbone.
The frame of a general motorcycle, such as a straddle or pedal type, is basically composed of large and small steel tubes, bent and combined.
The frame of the bent beam car is a little different, and the main part of the frame is spliced by steel pipes and steel plates.
Therefore, this kind of frame is also called steel pipe and steel plate hybrid spine frame in foreign countries.
As we all know in the industry, the gap between the steel pipe and the steel plate is very large, and if you want to splice them together, strength has become a very important problem.
In addition, the bending degree of the steel pipe on the frame of the bending beam car is much larger than that of the general frame.
If you want to form steel pipes, you need better pipe benders.
At present, the existing pipe bender level of Hongda Machinery Factory, it is indeed difficult to make the main beam of the frame of the bending beam car.
After looking at the parts diagram for a while, Zhao Guoyang found that a bend at the spine of the frame, and the connection between this bend and the steel plate below, is a difficult point for the entire frame.
"Well, it seems like it's a bit of a hassle for a while.
The bending of the elbow can be solved if it is too large, but it is not possible to use square pipe splicing.
However, the strength of the weld between the elbow and the flat plate is a big problem.
Zhao Guoyang thought secretly.
The spine of the frame of the bending beam car is relatively large because it is the position where the driver sits.
If the welding is not strong enough, it is easy to cause safety problems, which Zhao Guoyang knows.
In this era, laser welding is far from popular, and Zhao Guoyang is also a clever woman who has no rice.

If there is a laser welding machine, the problem is much easier to solve.
Just when Zhao Guoyang went through 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 was leaking.
Xu Dongfeng came in panting and shouted.
"What kind of fuel tank leaks" Hearing this, Hua Guosheng was shocked.
Mingke Tractor Factory is an old customer of Hongda Machinery Factory.
For a long time, the production volume of this plant has been relatively stable, although it is not large, but it has never been interrupted.
Basically, it's like 20 or 30 fuel tanks a month.
A few days ago, a large order suddenly came to the Minke Tractor Factory.
There were middlemen from the western provinces who asked them to order one hundred and twenty 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 tasks to the technical department, and asked Hua Guosheng, an old technician, to be responsible for the production of this batch of fuel tanks.
Zhao Guoyang heard Xu Dongfeng talk about this matter yesterday.
He is Hua Guosheng's apprentice, so he naturally wants to follow Hua Guosheng.
Originally, after a few days of busyness, most of this batch of fuel tanks has been completed, and it should be swept up today.
Who knew that there was a sudden oil leak, and Hua Guosheng was extremely nervous, which is understandable.
Just when Zhao Guoyang was stunned, Hua Guosheng had already stood up and hurriedly ran to the door.
While running, he asked Xu Dongfeng: "Xiao Xu, is there a large number of oil leaking fuel tanks, how many are there in total?"
"Just checked ten of them, and only three are good."
Xu Dongfeng replied.
Xu Dongfeng's words were like a thunderbolt, and he almost didn't shake Hua Guosheng down
