   "Master Hua, I have something to trouble you. I have a blueprint for a new product later, and you have to help me. I'm afraid I can't do it alone." Zhao Guoyang said to Hua Guosheng sincerely.

   "This is no problem. I can still draw general tooling drawings. However, if it is too complicated..." Hua Guosheng rubbed his hands and said a little awkwardly.

   "Don't worry, Master Hua, I will draw the complicated ones myself!" Zhao Guoyang quickly 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 the Hongta Mountain where Zhao Guoyang was scattered, everyone naturally congratulated and chatted lively for a while, and then everyone went to their own business.

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

   "Ah, is there no real thing?" Hua Guosheng was a little surprised after receiving these pictures.

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

  When Hua Guosheng heard the words, a look of embarrassment appeared on his face.

  Indeed, in this era, it is not so difficult to design tooling drawings without real objects.

  Because it is difficult for ordinary technicians to imagine the specific appearance of a part from a two-dimensional drawing. Only with the help of real objects and two-dimensional drawings can we know what a part looks like after it is formed.

  Of course, some simple parts can still be seen through the two-dimensional diagram.

   In comparison, Zhao Guoyang is extremely different.

  Although computers are not yet popular in this era, and there is no 3D software such as PRO-E and UG, but he only needs to look at the 2D drawing of the part, basically, the 3D image has already been displayed in his mind.

  Such ability can only be possessed by top engineers who have drawn thousands of parts drawings and have been in contact with various types of mechanical parts.

  Undoubtedly, in his previous life, as a senior engineer who enjoyed special allowances from the State Council, Zhao Guoyang must have such abilities.

"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 will draw a rough outline of these parts for you. With this, you should Then you can draw the tooling diagram." Zhao Guoyang said in relief.

   "Okay, if Guoyang, you can really draw the general appearance of the parts, I promise to complete the task!" Hua Guosheng picked up the drawing, nodded vigorously and said.

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

  After the new frame is designed, he must communicate with the production with a 3D drawing that has a good effect, otherwise, the workers in the workshop will not be able to make it according to the 2D drawing.

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

   On the general drawing, there is nothing special about it. After just a few glances, Zhao Guoyang knew how to dissect the frame.

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

  The main reason why the curved beam frame is difficult to manufacture is its spine.

  General motorcycles, such as straddle type or pedal type, the frame is basically composed of large and small steel pipes, bent and merged.

  The curved beam frame is somewhat different. The main part of the frame is made of steel pipes and steel plates. Therefore, this kind 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 them together, the strength becomes a very important issue.

  In addition, on the frame of the curved beam car, the bending degree of the steel pipe is much larger than that of the general frame.

  If you want to form steel pipes, you need a better pipe bender. With the existing pipe bending machine level of Hongda Machinery Factory, it is really difficult to make the main beam of the bent beam frame. .

   After looking at the parts diagram for a while, Zhao Guoyang discovered a bend pipe at the backbone of the frame, and the connection between the bend pipe and the steel plate below, which is a difficult point of the whole frame.

"Well, this problem seems to be really troublesome for a while. It can be solved if the bent pipe is too big. If it doesn't work, you can use square pipes to splice it. But the welding strength between the bent pipe and the flat plate is It's a big problem." Zhao Guoyang thought to himself.

  The backbone of the frame of the curved beam vehicle 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. Zhao Guoyang knows this well.

  In this day and age, laser welding is far from popular, and Zhao Guoyang is also a clever woman who can hardly cook without rice. If there is a laser welding machine, the problem will be solved much better.

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

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

   "What? The fuel tank is leaking?" 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 factory has been relatively stable. Although it is not large, it has never been interrupted.

  Basically, there are twenty or thirty fuel tanks per month.

  A few days ago, Minco Tractor Factory suddenly received a big order. Some middlemen in 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 not a small deal for Hongda Machinery Factory.

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

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

  After a few days of busy work, most of these fuel tanks have been completed, and it should be finished today. Who knew that there was an oil spill suddenly, and it was understandable that Hua Guosheng was extremely nervous.

   While Zhao Guoyang was in a daze, Hua Guosheng had already stood up and hurried to the door. While running, he asked Xu Dongfeng: "Xiao Xu, how many fuel tanks are leaking? How many are there?"

   "I checked ten just now, and only three are good." Xu Dongfeng replied.

  Xu Dongfeng's words were like a thunderbolt, almost knocking Hua Guosheng down. .
