Hu Yang admired Lin Zhenhua's design very much, not only helped him make a wooden model, but also personally corrected several design defects for him. Lin Zhenhua was still a little arrogant, and felt that he was a dignified graduate student of Huaqing University, and he should be unmatched in Hanhua Machinery Factory, but Hu Yang gave him a few points, which made him completely convinced.

"Lao Hu, what is your education?" Lin Zhenhua couldn't help but inquire.

"Well, it's high school." Hu Yang said.

"When you were in high school, you were in the 50s, right? Amazing, high school students in the 50s are also highly educated, and they are even better than current college students. ”

"Well, I'd like to have a lower education. The more knowledge I have, the more reactionary I become, and I just suffer the loss of being educated. Hu Yang said with a little sentimentality.

"Lao Hu, what does your family do, those who can go to high school in the 50s should not be an ordinary family."

"My family, my family is relatively high, don't mention it, don't mention it." Populus flatly avoided the topic.

Lin Zhenhua knows that although it has reached the era of reform and opening up, everyone still has some scruples in their hearts, and when it comes to some sensitive topics, they often adopt an evasive attitude. It is also inconvenient for him to conduct in-depth research on the life experience of Populus euphratica, but he just recognizes one point, this Populus euphratica is definitely a talent, and he may have to ask him more in the future.

Zhao Yongqun took the wooden mold made of poplar to his father Zhao Dawei, and Zhao Dawei did not delay at all, and directly made a sand mold and cast a set of castings for Lin Zhenhua. When Lin Zhenhua returned to the metalworking workshop with the casting, it was already time to get off work, and the workers in the workshop were gone, leaving only Yang Xin waiting for him.

"Brother Xiaohua, what did you say you made for me?" Yang Xin asked.

"Ah, I just came from the sand turning workshop and cast a few major workpieces." Lin Zhenhua said.

"So what's next?"

"Look."

Lin Zhenhua said, opened Yang Xin's milling machine, and began to process other components. When you encounter some parts, you have to run to the lathe next to them to process them. The management of equipment in the workshop is not so strict, and those who don't know how to use the equipment will naturally not open the equipment, and those who can use it will not be a big deal to start the equipment and do some private work. It's like in the office of later generations, whoever uses a computer, photocopier, fax machine, etc., after work, even if the unit leader sees it, he will not say anything.

The materials used by Lin Zhenhua are all leftovers collected from scrap iron piles, and they don't cost a penny in the factory, so naturally no one interferes. If you have the ability to process a car from scraps by yourself, the factory leaders will only praise you for your ability, and will not think of anything like embezzlement of public property.

After a while, gears, shafts, connecting rods, paddles, and the like were all ready. Lin Zhenhua assembled all the parts, one set of gears was connected to the X-axis of the milling machine, and the other set of gears was connected to the universal indexing head, and a simple gear hobbing machine was born. The principle of this gear hobbing machine is actually to use the x-axis of the milling machine itself to drive the universal indexing head to rotate automatically, so that the work of the rotary indexing head that should be completed by the worker is automatically completed by the machine, so that the whole milling gear is fully mechanized, and the efficiency is naturally greatly improved.

"This is what you call a gear hobbing machine?" Yang Xin looked at this weird attachment and asked distrustfully. It is no wonder that the gear hobbing machine made by Lin Zhenhua only considers the practical surname, and cannot take into account the beauty at all. Several castings should have been polished and other treatments, but Lin Zhenhua also omitted them, making this copycat gear hobbing machine look even more hideous.

"Here, I'll show you." Lin Zhenhua said. He picked up a gear blank, stuck it on the universal indexing head, and started the milling machine directly.

I saw that the milling cutter rotated rapidly, cutting out a tooth on the blank, and then, the blank workpiece slowly retreated to the side, leaving the processing area of the milling cutter, and the universal indexing head slowly rotated at the same time, driving the workpiece to rotate at an angle. After the workpiece is turned to the right angle, the feed movement starts again, the workpiece is again facing the milling cutter, and another beautiful tooth blooms under the milling cutter.

"It's amazing!" Yang Xinhuan shouted, "Brother Xiaohua, how does it know how many angles to turn, why is it so coincidental?" ”

Lin Zhenhua almost wanted to hide his face and leave: "Yang Xin, do you have a good conscience, these angles have to be calculated, do you know what time I counted last night?" ”

"With this thing, it's so easy to machine gears!"

"Nonsense, why don't I work so hard to make this gear hobbing machine for you?"

"Thank you, Brother Hua." Yang Xin said sweetly.

"Okay, the test was successful." Lin Zhenhua stopped the milling machine, removed a milled gear from the chuck, and then said to Yang Xin: "Now you can rest assured, you will definitely be able to complete the task ahead of schedule." ”

"I'll give it a try."

"Yang Xin, it's off work now, and it's late." Lin Zhenhua reminded.

"Brother Xiaohua, you go home first, I'm going to try this new machine." Yang Xin is like a child who has got a new toy, and can't help but use it first.

"Okay, I'll go back first, I'm really hungry." Lin Zhenhua waved his hand to Yang Xin and walked away. He doesn't have to worry about whether it is safe for Yang Xin to get off work too late, there are workers who work night shifts in other workshops, and there are militiamen patrolling in the factory area, so there is no problem with public security.

The next morning, Lin Zhenhua, as usual, stepped on the bell to go to work and walked into the workshop, but saw that everyone was looking at him with strange eyes. He subconsciously reached out and touched his face, thinking that it was because of engine oil on his face, or a lipstick mark or something.

"What's the matter, why are people looking at me like this?" Lin Zhenhua got into the small room of the handling squad and asked Xiong Lijun.

"Xiaolin, you didn't do anything illegal, did you?" Xiong Lijun asked.

"Didn't you?" Lin Zhenhua himself is not convinced.

"Early this morning, Director Luo has already gone to the handling class to find you three times, let us inform you that as soon as you arrive at the workshop, you will go to him immediately." Xiong Lijun said, the director Luo he said refers to Luo Qinsheng, the director of the metalworking workshop, who is a veteran lathe worker with more than 20 years of experience.

Lin Zhenhua somehow, nervously came to the workshop director's office, as soon as he entered the door, he saw Luo Qinsheng and several other workers were studying a gear, including Peng Gang, the milling squad leader, this is the best milling worker in the entire Hanhua Machinery Factory, forty-seven or eighteen years old, studied in junior high school, proficient in various types of milling machines.

"Director Luo, are you looking for me?" Lin Zhenhua asked.

"Xiaolin, come on, come on, that's right, it's me looking for you." Luo Qinsheng said, Lin Zhenhua could hear from his tone that it didn't seem to be a bad thing.

"Director Luo, is there something wrong?"

"This gear, do you know what's going on?" Luo Qinsheng showed the gear in his hand to Lin Zhenhua.

Lin Zhenhua glanced at it and recognized that this was the product from the gear hobbing machine he had transformed for Yang Xin, so he nodded and said, "I know, this should be processed by Yang Xin." ”

"That's right!" Luo Qinsheng slapped his thigh, "Xiaolin, do you know how many gears Yang Xin processed last night?" There are 250 of them, which is equivalent to a week's workload for one of our masters. ”

Peng Gang added: "I didn't believe it at first, thinking that she was cutting corners, but I took more than a dozen calipers, all of which were qualified, and it was like the same cutter milling, there was no difference at all." ”

This is normal, Lin Zhenhua thought with disdain in his heart that with the gear hobbing machine, the entire gear processing process is completed automatically by the machine, without manual participation, let alone processing 250, even if 2500 are processed, it is the same quality.

"Xiaolin, Yang Xin said, the reason why she can process so many gears so quickly is because you made her a gear hobbing machine, isn't that so?" Luo Qinsheng continued.

Lin Zhenhua knew that this matter must not be hidden, so he nodded and said: "That's the case, but well, this gear hobbing machine was not designed by me alone, and Master Hu Yang of the sand turning workshop also participated in the design." ”

"Old Hu?" Luo Qinsheng said, "No wonder, he is a genius. ”

No way? Lin Zhenhua secretly exclaimed to himself, Populus Hu is a genius, and I, Lin Zhenhua, am not stupid, I said that Populus Hu participated in the design, just to be modest, you can't give all my credit to Populus Hu.

"Well, this gear hobbing machine, the main thing is that I saw others do this in the past when I was in the army, and then I imitated it. Master Hu also dialed me in some places. Lin Zhenhua said.

Luo Qinsheng nodded again and again: "I understand, I understand." Kobayashi, it's really good that you've done this. We are very nervous about our machining tasks, and the gear hobbing machine you designed will solve the problem of gear machining at once, and we can free up other milling workers to complete other tasks. You're our hero. ”

"That's what I'm supposed to do." Lin Zhenhua said.

"It's not easy. Xiaolin, in a situation like yours that takes the initiative to engage in technological innovation, we plan to report it to the factory department, and the factory department will definitely give you a reward. ”

"Rewarded?" Lin Zhenhua's eyes were full of golden light, "Director Luo, are you saying that there is a bonus to take?" ”

"Absolutely!" Luo Qinsheng said, "Now Vice Chairman Ye advocates scientific and technological research, and our factory has also set up a technological innovation award. A gear hobbing machine like the one you invent now will definitely win awards. As for the bonus......"

"The first prize is three dollars." Peng Gang said, and when he said this, his eyes were shining, and he seemed to see three one-yuan bills floating in front of him. The eldest son of Peng Gang's family is preparing to get married, and the family's economic conditions are very tight, and three yuan is also very tempting for him.

"Three?" At that moment, Lin Zhenhua just wanted to jam the factory director's head on the gear hobbing machine and sharpen it a few times, so that he could open his mind. His design has increased the production efficiency by ten times, which is equivalent to saving the workload of dozens of people, and the bonus is only three yuan!

Luo Qinsheng didn't notice Lin Zhenhua's disappointment, he felt that three yuan was also a good amount of money, at the end of each month, the workers could turn the world upside down in order to reduce the overtime pay of five cents, Lin Zhenhua was a small young worker, and he was not happy to get a bonus of three yuan? He said to Lin Zhenhua: "Xiaolin, don't worry, I will definitely be able to win a first prize for you, but don't you work hard in the past two days, and then make us two sets of gear hobbing machines and install them on other milling machines." ”
