The Grandmother in the Siheyuan

Chapter 100 Meeting

Looking at Liu Hua's expression, Li Huaide knew what he wanted to say, and he had no way to refute it. After all, his deeds were even worse than Liu Hua's.

He could only talk about something else and change the subject: "Recently, our superiors have given us a big task. You, the equipment department, must keep up with it. You must not fall behind."

"Don't worry about that. The equipment department is now strong and the technical secondary school students are also on the right track." Liu Hua said jokingly: "Our Chief Ma now only regrets that he has all the skills to slay dragons, but has no place to use them."

It was not until the next day when Liu Hua went to work that he found out what kind of big order it was. The large order for gears left Liu Hua confused.

He found Li Huaide and said, "These gears should not be produced by our factory. We have no experience in producing gears before."

Li Huaide nodded: "Time is tight and the task is heavy. All factories near the capital that have technical strength and can produce gears have been assigned this order."

Liu Hua shook his head: "It is simply wishful thinking to want to mass-produce gears with our current machine tools. Even experienced workers can't produce many gears in a day. This equipment is not professional."

Li Huaide said with a bitter face: "I know that, but this is a mission, a mission that cannot be refused, unless we don't want to think about it."

He patted Liu Hua on the shoulder and said, "Can't you make a machine specifically for producing gears? Gears are a small thing with a wide range of applications. The engineers in the department told me that there will be a lot of such tasks in the future."

Of course there are machines for producing gears, aren't they gear hobbing machines? Fully automatic gear hobbing machines produce gears very efficiently, so this task can be easily accomplished.

But if a fully automatic gear hobbing machine could become a fully automatic CNC machine tool, Liu Hua would probably get some kind of medal.

Moreover, China's technology in electrical automation is weak, semiconductors are inherently weak, and coupled with poor economic conditions and a shortage of talent, even if there are CNC lathes, there are not enough people to operate them.

So the idea of CNC gear hobbing machine can be ignored. Even if Liu Hua wants to make it, it is not something he can do casually. You should know that in 1958, the Beijing No. 1 Machine Tool Factory and Wudaokou jointly developed a three-coordinate machine, but it was just a development and there was no follow-up.

This is a systematic project and cannot be achieved overnight.

Liu Hua was strolling around the workshop. The workers around him were racing against time to produce gears. Using semi-automatic machine tools to produce gears was a very tedious task that required constant measurements. The production speed could not be increased and the gears were often scrapped.

Liu Hua was watching a senior worker working beside the machine tool when Zhang Lijuan walked in from outside the workshop. "Go back to the office. Your master is going to hold a meeting to discuss how to produce this gear in order to improve production efficiency."

A senior worker nearby also complained: "It's time to think of a solution. With the way we produce, it will take us a long time to complete the task. I have been busy with gear tasks all month."

The office was already filled with smoke. The last time Liu Hua saw so many auspicious clouds was in the Transportation Department. At that time, they couldn't solve the brake problem, and there was really no way to relieve their worries except smoke.

Unfortunately, Liu Hua is not Gargamel and doesn’t like the feeling of being shrouded in smoke.

Sister Zhang quickly opened the windows and doors to ventilate the room: "You men smoke when you are upset, and if you smoke again, you will set the house on fire."

Liu Hua made himself a cup of tea and sat opposite Ma Yushan. Ma Yushan nodded and said, "Go ahead, speak freely. What do you think about this mission?" Several technicians talked about the difficulties of producing gears. Ma Yushan frowned and said, "I know the difficulties. Now I need a solution. Even if you don't have a solution, tell me a direction for the solution. As long as it may be effective, we will work hard in this direction."

Liu Hua had just looked at it in the workshop. The first thing to do is to determine the angle of the gear, which is the most important thing.

There was no way. When he started to come into contact with machine tools, most of them were already CNC machine tools, so Liu Hua had never come into contact with some very practical tools on semi-automatic machine tools.

Liu Hua searched his knowledge base for useful information. A word he hadn't seen for a long time suddenly came to his mind. Liu Hua blurted out: "Dividing head."

Ma Yushan was lighting a cigarette when he suddenly froze and asked, "Hua Zi, what did you just say? What is a dividing head? What does it do? Tell me in detail."

Liu Hua frowned and began to search for the definition of this unfamiliar word in his mind: "A machine tool accessory that can be used to clamp workpieces to position and rotate them at equal angles."

This was the definition of the graduation diagram in the book when Liu Hua was studying. Ma Yushan understood what it meant as soon as he heard it.

"Bang." Ma Yushan said excitedly: "This can be used in gear production. The rotation of the angle is divided into equal parts. After the angle is determined, the gear can be cut boldly. The biggest difficulty in our current production is that we cannot determine the gear angle."

Ma Yushan was so happy. Although he was not the one who solved the problem, this disciple was his and he felt proud of it.

"Okay, do you have any idea about the design of this dividing head?"

Liu Hua thought for a moment and said, "I need to think about this carefully."

It's not Liu Hua's fault. He has never come into contact with the dividing head used in semi-automatic machine tools. He has only seen it in books. Although his memory is very good now, he cannot realize the specific functions based on pictures alone.

No matter what others said, Liu Hua returned to his desk, picked up a piece of white paper and drawing tools, and drew the dividing head from his memory.

Of course, you need to have specific functions in advance, and just a picture is not enough, but you can slowly work your way up.

With Liu Hua's current drawing skills, it is very easy for him to draw an appearance drawing of a dividing head. After he finished drawing it, all the technicians gathered around the drawing and started discussing.

Before, everyone just had no concept of the dividing head. Now that they had a rough diagram and Liu Hua’s definition, after a lively discussion, they actually analyzed the usage of the dividing head in detail.

Liu Hua drew the picture while the others gathered around to discuss and make revisions. Before leaving get off work, a fresh dividing head drawing was almost ready.

Ma Yushan clapped his hands in satisfaction and said, "Not bad, not bad. Today's Zhuge meeting was quite successful. Tomorrow, unless it affects production, we will put aside all the things on hand and go all out to produce this dividing head and show the strength of our technical department."
