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

Niu Xiaoqiang was no longer verbose, stretched out his hand and pointed to the machine tool to explain: "What you see now is a gun drilling machine tool, this type of machine tool is specially used for deep hole processing, what is called deep hole processing? To put it bluntly, it is drilling, for example, the gun drilling machine of the 311 factory is used to drill the barrel. ”

Niu Xiaoqiang paused slightly when he said this, leaving time for questions, but no one raised his hand, so he continued: "Look here, this is the gun drill of the machine tool, that is, the cutter head that the insiders say, the processing tools of each machine tool are different, which is mainly due to the different nature of their work, the gun drilling machine tool is mainly used for drilling, so its tools are drill bit shapes. ”

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 lot of types of machine tools, such as gun drilling machine tools, milling machines, planers, stamping machine tools, hobbing machine tools, etc., etc., I said too much You may feel confused, let's simply divide it from the main category, machine tools are roughly divided into three categories, namely metal cutting machine tools, forging machine tools and woodworking machine tools, the gun drilling machine tools you see now belong to the category of metal cutting machine tools. ”

Niu Huahua then asked, "Brother Xiaoqiang, what is the difference between these three?"

Niu Xiaoqiang smiled: "From the name, you can see the difference between these three kinds of machine tools, first of all, metal cutting machine tools, the focus is on the word cutting, that is to say, this machine tool is processed by cutting, and the focus of forging machine tools is the two words forging, as the name suggests, this kind of machine tool is processed by forging and strong pressure, as for the final woodworking machine tool, this type of machine tool mainly processes wood materials, and is distinguished by the raw materials processed. ”

Everyone nodded again and again, Niu Xiaoqiang looked around and found that no one raised his hand, so he continued to explain: "This is the drill pipe box of the gun drilling machine tool, as we all know, any machinery and equipment need to be converted into kinetic energy, the drill pipe box is the main component of the gun drilling machine tool to achieve kinetic energy conversion, it is driven by power supply, and then the electricity is converted into mechanical force, and then through the transmission gear to drive the drill bit to run, this part is very critical, and it is easy to have problems, so it usually needs to be maintained and maintained frequently." ”

Niu Xiaodong raised his right hand: "Isn't it just like the engine?"

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

Niu Xiaodong originally wanted to show off, but not only did he fail to show off, but he also lost face, and he closed his mouth a little embarrassed and stopped talking.

In the following time, Niu Xiaoqiang continued to explain various structures:

"This is a chip collector for a gun drilling machine, which is mainly used to collect and preserve metal chips generated during drilling......"

"This is an oil feeder, which is mainly used for cooling......"

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

After 20 minutes of explanation, the three of them roughly figured out the structure and working principle of each part of this gun drilling machine. Niu Huahua couldn't help but sigh: "Brother Xiaoqiang, you are so powerful, you actually know so much." ”

Niu Xiaoyong nodded sympathetically: "Brother Qiang, it's really condescending for you not to be a teacher, I think you speak better than Teacher Li." ”

Niu Xiaodong is not far behind: "Brother Qiang, you have made me fully understand what a cow break!"

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

"Familiar. ”

"Okay, I'm going to do the actual operation demonstration next, do you see the lines drawn on the ground? This is the operation area specially planned by the 311 factory, you must pay attention to keep your distance, don't get too close, understand?"

The three of them were all half-grown children, and they had already been itching, and when they heard this, they all nodded vigorously, urging Niu Xiaoqiang to start the machine quickly.

Niu Xiaoqiang turned on the power switch, and at the same time explained the precautions: "Safety is the top priority when operating the machine tool, once you find a possible danger, you must get out of the operating post and hide in the safety area. It is difficult to prevent these accidents, so before production, we must carefully check the work to minimize the probability of accidents. ”

He said here and pointed to the operation manual posted next to the machine tool, "This is the experience summed up by the workers and masters, especially the precautions, you must keep it in mind." ”

Under the supervision of Niu Xiaoqiang, the three of them memorized all the precautions on the operation manual, and then Niu Xiaoqiang supervised everyone to check according to the process, and only after the inspection was completed did the actual operation demonstration begin.

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

Niu Xiaoqiang was still thinking about helping Fang Dongping do the 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, and then said uncertainly: "Master, the order you received this time should not be to help someone design an engine, right?"

"Well, this time we designed a diesel engine. After Fang Dongping finished speaking, he continued to work on the scratch paper.

Relying on the strength of one person to design a diesel engine sounds a bit fantastical, but this 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 direction was engine technology, and he also participated in the research and development of a certain type of tank engine in China, so his experience in this area is very rich.

Niu Xiaoqiang once saw the scrapped engine cylinder in the scrap warehouse of the arsenal, and asked Fang Dongping about the engine because of curiosity. According to Fang Dongping, the cylinder processed by the 311 factory is mainly used for the Type 59 tank, which is a B2 series V-shaped 12-cylinder water-cooled diesel engine, and its technical parameters are very advanced in China, but if you look at the world, it is only barely equivalent to a third-rate product.
