Chapter 24 Gear Hobbing Machine

Yang Chunshan emphasized "half a son" in front of Lin Zhenhua, and Lin Zhenhua could understand it.He said that he has been working hard, and he is not completely perfunctory.Among other things, just say that now, Lin Zhenhua is racking his brains to design a copycat gear hobbing machine for Yang Xin, so as to free Yang Xin from the heavy work like a mountain.

Ever since Lin Zhenhua taught Yang Xin to use the dividing head, such work as machining gears has been difficult for Yang Xin.But as the old saying goes, good luck comes with misfortune. Yang Xin learned how to process gears, but let himself fall into the dilemma of being able to do more work.

The factory has recently received a batch of orders, and there are more than 1000 kinds of gears alone.There are only a dozen milling workers in the factory, and they also have to undertake the processing of other parts, so there are as many as five or six hundred gear processing tasks assigned to Yang Xin's master, Jiang Tiemei.The child of Jiang Tiemei's family had measles just at this time. Jiang Tiemei saw that Yang Xin could turn gears, so he handed over all these tasks to Yang Xin, and asked for leave to go home to take care of the child.

Yang Xin is an obedient girl, she didn't know how to defend herself when she received the task assigned by her master, she just followed it foolishly, until she was in a state of forgetting to sleep and eat, but she was still far away from completing the task.

"Brother Xiaohua, tell my parents that I'm working overtime and I'm going to be home late for dinner." Yang Xin said to Lin Zhenhua who was about to get off work while sweating profusely while turning the indexing head.The little girl's bangs were soaked with sweat and stuck to her forehead, which made Lin Zhenhua feel distressed after seeing it so well.

"No way, sister, you have been working overtime for four or five days in a row. Why, are you going to compete for this year's production pacesetter?" Lin Zhenhua said with a smile on his face.

"I don't have the heart to think about this. My master's mission is still a long way off." Yang Xin said in a nasal voice, unable to tell whether it was a cold from exhaustion or the desire to cry.

"I see that you have been milling gears these days, why haven't you finished milling?"

"There are more than 500, and now only more than 100 have been completed."

"No way?" Lin Zhenhua said, "Mill more than 500 gears with a universal milling machine? This work should be done with a gear hobbing machine."

"What is a hobbing machine?" Yang Xin asked.

"Gear hobbing machine..." Lin Zhenhua scratched his head, "I can't tell you clearly, anyway, it is a machine specially used for processing gears."

"I've never heard of it." Yang Xin said dejectedly.

In fact, this cannot be blamed on Yang Xin's ignorance. The gear hobbing machine is a special machine for processing gears. It has the advantages of high processing precision and fast speed, and is generally suitable for mass production of gears.At that time, China lacked all kinds of machinery and equipment, and only a few large-scale machinery enterprises had gear hobbing machines. It was impossible for medium-sized enterprises like Hanhua Machinery Factory to use them.In Hanhua Machinery Factory, if it is necessary to process gears, it can only be done by using a universal milling machine combined with an indexing head, as Lin Zhenhua taught Yang Xin to do last time.

Using a universal milling machine with an indexing head to process gears does not matter when the quantity is small, but it is very troublesome to process hundreds of gears at a time.To process each gear, the indexing head must be rotated dozens of times repeatedly, and the tool must be re-set every time it is rotated, and then a tooth can be milled out.Turn it again, then set the tool, and mill another tooth, and the cycle goes on and on, and the workload is very scary.Yang Xin has already turned himself dizzy after turning the indexing head these days.

"Xiaohua, you have the time, can you help me cut a few?" Yang Xin couldn't help but said, seeing Lin Zhenhua's idle look.She knew that Lin Zhenhua's technique was excellent, so she was idle anyway.

"I don't want to do such unskilled things." Lin Zhenhua said very shamelessly.

"Damn Xiaohua, you really won't help me?" Yang Xin raised her brows. The girls in the factory were all a little short-tempered, and she was already considered a gentler kind.

Lin Zhenhua shook his head: "I didn't say I won't help you, I just said that I don't do such unskilled things. How about this, you go home from get off work today, I will think about it and design a copycat version for you The gear hobbing machine can process your 500 gears in one day."

"What is a cottage?"

"Shanzhai, that is... do you know that the countryside surrounds the city? Shanzhai means millet plus rifles." Lin Zhenhua said in a language that people at the time could understand.

"You mean the cheap way, don't you?"

"You can understand it that way."

"You said that 500 gears can be processed in one day?"

"Uh, maybe not that fast, but more than 400, it should be no problem."

"Really? Then I'm off work now, and I'm waiting for your fake machine tomorrow." Yang Xin happily turned off the machine tool, threw the gauze gloves into the toolbox, and followed Lin Zhenhua home.

These days, Yang Xin often heard Yang Chunshan sigh at home, saying that Lin Zhenhua's skills are really unfathomable, not only milling, electric welding, but also other kinds of work, he didn't see any kind of skills Lin Zhenhua can't do it at all.Yang Xin had a blind trust in Lin Zhenhua. Hearing what his father said, he directly raised his opinion of Lin Zhenhua from admiration to superstition.Now Lin Zhenhua said that he could help her design a machine. As for whether it is called a gear hobbing machine or a counterfeit machine, she doesn't care. She only knows that what Brother Xiaohua promised will definitely not fail.Brother Xiaohua's character is like the gears in a gearbox, which are precise and reliable.

Lin Zhenhua agreed to design a counterfeit gear hobbing machine for Yang Xin, not on a whim. He had read relevant literature in the past and knew that a universal milling machine could be transformed into a simple gear hobbing machine.When he got home, he thought over the whole principle several times, deduced it on the diagram for a long time, and finally drew a few blueprints.The next day, he came to the foundry workshop with the blueprint in his hand to find his buddy Zhao Yongqun, and asked him to cast some workpieces for him.

In Hanhua Machinery Factory, it is very common for workers to use the equipment and materials in the factory to do private work.For example, none of the briquette stoves used by every household in the factory was bought from a store, but the workers got some scrap iron sheets, scrap steel bars and other things to weld them out by themselves.The factory leaders will not interfere with workers doing this kind of private work. They rely on mountains to eat mountains, and rely on water to eat water. As a worker in the factory, how can they not take advantage of the factory.In fact, the briquette stove in the factory leader's own home was also made by workers. The upper beam is so straight, so is the lower beam necessary to be so straight?

"Yongqun, there are several such workpieces, can you cast them for me?" Lin Zhenhua took out the drawings and handed them to Zhao Yongqun.

Zhao Yongqun took the drawing and looked at it, simulated the appearance of the workpiece with his hands, and asked doubtfully, "What is this for?"

Lin Zhenhua chuckled: "That's right, brother, the blueprint looks a bit better now."

Zhao Yongqun said: "It's not that you teach well. You don't want to praise yourself, do you?"

Zhao Yongqun is a general worker in the foundry workshop. He usually doesn't need to read the drawings, and there is no master to teach him how to read the drawings.After Lin Zhenhua came back, he, Chu Hongyang, Peng Shaozhe and others got together to form a study group, and taught them mechanical principles and other related knowledge when they had nothing to do.Zhao Yongqun learned mechanical map recognition from Lin Zhenhua, otherwise he would not be able to imagine the appearance of the workpiece from a three-view image.

Lin Zhenhua didn't explain anything to Zhao Yongqun, just asked: "I am useful for this thing, and it is related to my sex...happiness in the second half of my life. Tell me something sweet, can you help me make it."

Zhao Yongqun nodded and said: "These little things don't need much molten iron. I'll see which furnace has a little more molten iron later. Just ask my dad to cast one for you."

Zhao Yongqun's father, Zhao Dawei, was a foundry worker. When casting workpieces, sometimes there would be some surplus molten iron in a furnace.

"Then thank you dad." Lin Zhenhua said, turning around to leave.

"You left like this?" Zhao Yongqun shouted.

Lin Zhenhua said: "Why, brother asks you to work, and you still have to tip you?"

Zhao Yongqun said: "You want to cast a workpiece, where is the wooden mold? My dad is a sand maker, he can only make sand molds, but he doesn't care about making wooden molds."

"Yeah, there's still this link." Lin Zhenhua patted his head.

"You have to go to the wooden model class to find someone to help make wooden models, and then give it to my dad to make sand models. How about you go to Lao Hu, who is good at skills, good people, and easy to talk to." Zhao Yongqun suggested.

"Who is Lao Hu?" Lin Zhenhua asked.

"It's Populus euphratica? Don't you know him?"

"Hu Yang? I have a little impression, where is he?"

"Wooden modeling class, I'll take you there."
