Manufacturing Empire in the Valley

Chapter 83 Diesel Engines

Niu Xiaodong nodded again and again: "Brother Qiang, don't worry, we will definitely bring up what you don't understand."

Niu Xiaoqiang stopped talking, and pointed to the machine tool to explain: "What you are seeing now is a gun drilling machine tool. This type of machine tool is specially used for deep hole processing. What is deep hole processing? To put it bluntly. The only thing to do is to drill holes, for example, the gun drilling machines in Factory 311 are used to drill gun barrels."

Niu Xiaoqiang paused for a moment when he said this, leaving time for questions, but no one raised his hand, so he continued: "Look here, everyone, this is a gun drill for a machine tool, which is what people in the industry call a cutter head. The processing tools of each machine tool are different, which is mainly due to the different nature of their work. The gun drilling machine is mainly used for drilling, so its tools are in the shape of drill bits.”

Niu Xiaoqiang paused again when he said this, and this time Niu Huahua raised his right hand: "Brother Xiaoqiang, can you tell us about the types of machine tools, so that we can have a general impression."

Niu Xiaoqiang nodded: "Of course there is no problem with this. There are quite a few types of machine tools, such as gun drilling machines, milling machines, planers, stamping machines, gear hobbing machines, etc. If I say too much, you may feel confused. Let’s just divide it into categories. Machine tools are roughly divided into three categories, namely metal cutting machine tools, forging press machines and woodworking machine tools. The gun drilling machines you see now belong to the category of metal cutting machine tools.”

Niu Huahua then asked, "Brother Xiaoqiang, what's the difference between the three?"

Niu Xiaoqiang smiled: "The difference between these three machine tools can be seen from the names. The first is the metal cutting machine tool, and the focus is on the word cutting, which means that this machine tool is processed by cutting. The focus of forging machine tools lies in the word forging. As the name suggests, this type of machine tool is processed by forging and pressing. As for the final woodworking machine tool, this type of machine tool mainly processes wooden materials, which are distinguished by the raw materials processed. .”

Everyone nodded, and Niu Xiaoqiang looked around and found that no one raised his hand, so he continued to explain: "This is the drill box of the gun drilling machine. As we all know, any machine equipment needs kinetic energy conversion, and the drill box is the gun drill. The main part of the machine tool to realize the conversion of kinetic energy is driven by the power supply, and then converts the power into mechanical force, and then drives the drill bit to run through the transmission gear. This part is very critical and prone to problems, so it needs frequent maintenance and maintenance .”

Niu Xiaodong raised his right hand: "Is it just like an engine?"

Niu Xiaoqiang shook his head: "This metaphor is not accurate. It should be said that it is very similar to a gearbox. As for the metaphor of an engine, I think it is more like a servo motor on a machine tool."

Niu Xiaodong originally wanted to show off, but not only failed to show off, but also lost face, he closed his mouth in embarrassment and did not speak again.

In the following time, Niu Xiaoqiang continued to explain various structures:
"This is the chip collector of the gun drilling machine. It is mainly used to collect and save the metal chips generated during drilling..."

"This is the oiler, it's mainly used for cooling..."

"This is a vise, which is used to fix the workpiece..."

After 10 minutes of explanation, the three of them roughly understood the structure and working principle of each part of the gun drilling machine.Niu Huahua couldn't help sighing: "Brother Xiaoqiang, you are really amazing, you know so much."

Niu Xiaoyong nodded sympathetically: "Brother Qiang, it's a shame that you don't become a teacher. I think your speech is better than Teacher Li."

Niu Xiaodong was not far behind: "Brother Qiang, you made me fully realize what a bullshit is!"

Niu Xiaoqiang smiled and waved his hands: "Are you familiar with the structure of this machine tool?"

"Familiar."

"Okay, then I will conduct an actual operation demonstration. Do you see the lines drawn on the ground? This is the work area specially planned by Factory 311. You must pay attention to keeping a distance and don't get too close ,Understand?"

The three of them were half-grown children, and their hearts were itchy for a long time. They nodded vigorously when they heard this, and urged Niu Xiaoqiang to turn on the machine quickly.

Niu Xiaoqiang turned on the power switch, and at the same time explained to everyone the precautions: "Safety is the top priority when operating a machine tool. Once a possible danger is discovered, you must leave the operating post and hide in a safe area. Of course, in general There will be no major problems, but sometimes there may be some relatively rare accidents, such as vise breakage, knife head flying off, etc. These accidents are difficult to prevent, so before production, we It is necessary to do a good job in the inspection work carefully to minimize the probability of accidents."

When he said this, he pointed to the operation manual posted next to the machine tool, "This is the experience summed up by the master workers, especially the precautions, you must keep it in mind."

Under Niu Xiaoqiang's urging, the three of them memorized all the precautions in the operation manual, and then Niu Xiaoqiang supervised everyone to check according to the process. After the inspection, the actual operation demonstration began.

The actual operation demonstration is relatively simple, as long as you are not a fool, you can understand it at a glance.But if you want to learn superb processing technology, you need to accumulate experience, and you can't understand it just by looking at it.

Niu Xiaoqiang was still thinking about helping Fang Dongping with calculations. He felt that the time was almost up, so he turned off the equipment and walked into the workshop office with his three friends.

Fang Dongping was sitting at his desk drawing pictures, Niu Xiaoqiang walked up to him and took a look, then he said unsurely: "Master, the order you received this time should not be to help someone design an engine, right?"

"Well, this time the design is a diesel engine." After Fang Dongping finished speaking, he continued to work on the draft paper.

Designing a diesel engine by one person's strength sounds a bit far-fetched, but it is not the case here in Fang Dongping.

In his early years, he went to the Soviet Union to study for further study, and his main focus was engine technology. He also participated in the research and development of a certain type of tank engine in China, so he has very rich experience in this area.

Niu Xiaoqiang once saw a scrapped engine cylinder in the scrap warehouse of the arsenal. At that time, out of curiosity, he asked Fang Dongping about the engine.According to Fang Dongping, the cylinders processed by Factory 311 are mainly used for Type 59 tanks. This is a B2 series V-shaped 12-cylinder water-cooled diesel engine. Barely equivalent to third-rate products.
