Chapter 26 Technological Innovation

Hu Yang admired Lin Zhenhua's design very much. He not only helped him make wooden models, but also personally corrected several design defects for him.Lin Zhenhua was a bit arrogant at first, thinking that he, a dignified graduate student of Huaqing University, should be unmatched in Hanhua Machinery Factory, but the few points Hu Yang gave him made him completely convinced.

"Old Hu, what education do you have?" Lin Zhenhua couldn't help asking.

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

"When you were in high school, it must have been in the 50s, right? It's amazing. High school students in the 50s were considered highly educated, even better than college students today."

"Well, I wish I had a lower education level. The more I know, the more reactionary I am. I just suffer from being educated." Hu Yang said with some sentimentality.

"Old Hu, what does your family do? People who were able to go to high school in the 50s should not be ordinary families."

"My family, my family has a relatively high status, so don't mention it, don't mention it." Hu Yang categorically avoided this topic.

Lin Zhenhua knows that although we have entered the era of reform and opening up, everyone still has some scruples in their hearts. When it comes to some sensitive topics, they often adopt an evasive attitude.It is not convenient for him to delve into the life experience of Populus euphratica, but he is certain that Yang Yang is definitely a talent, and he may ask him more in the future.

Zhao Yongqun took the wooden mold made by Populus euphratica to his father Zhao Dawei. Without any delay, Zhao Dawei directly made a sand mold and cast a set of castings for Lin Zhenhua.When Lin Zhenhua returned to the metalworking workshop with the castings, it was already time to get off work, and all the workers in the workshop had left, only Yang Xin was left waiting for him.

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

"Hey, I just came from the foundry workshop and cast several major workpieces." Lin Zhenhua said.

"Then what's next?"

"Look here."

As Lin Zhenhua said, he turned on Yang Xin's milling machine and began to process other parts.When encountering some parts, they have to go to the lathe next to them for processing.The management of the equipment in the workshop is not so strict. People who don't know how to use the equipment will naturally not open the equipment, and those who can use the equipment to do some private work is not a big deal.It's like in the offices of later generations, whoever uses computers, copiers, fax machines, etc. after get off work, even if the unit leaders see it, they won't say much.

The materials used by Lin Zhenhua are all leftovers collected from scrap iron piles, and it does not cost a penny from the factory, so naturally no one interferes.If you have the ability to process a car out of leftover materials, the factory leaders will only praise you for your ability, and will not think of such things as embezzling public property.

After a while, gears, shafts, connecting rods, paddles and other things are 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. A simple gear hobbing machine was born.The principle of this kind of gear hobbing machine is to use the X-axis of the milling machine itself to drive the universal indexing head to rotate automatically, so that the work of rotating the indexing head that should be done by the operator is automatically completed by the machine. In this way, the whole The operation of milling gears has been fully mechanized, and the efficiency has naturally been greatly improved.

"Is this the gear hobbing machine you mentioned?" Yang Xin looked at this weird accessory and asked distrustfully.It's no wonder that the gear hobbing machine made by Lin Zhenhua only considered practicality, not aesthetics at all.Several castings should have been polished and other treatments, but Lin Zhenhua also omitted them, making this counterfeit gear hobbing machine look even more hideous.

"Come on, let me demonstrate to 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 the milling cutter rotating 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 dividing head rotated slowly at the same time, driving the workpiece Rotated by an angle.After the workpiece turns to a suitable angle, the feed movement restarts, and the workpiece goes against the milling cutter again, and another beautiful tooth blooms under the milling cutter.

"It's amazing!" Yang Xinhuan exclaimed, "Brother Xiaohua, how does it know how many angles to turn? How come it's such a coincidence?"

Lin Zhenhua almost wanted to hide his face and walk away: "Yang Xin, you have a little conscience, okay? These angles have to be calculated. Do you know what time I counted last night?"

"With this thing, machining gears is so easy!"

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

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

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

"let me try."

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

"Brother Xiaohua, you go home first, I want to try this new machine." Yang Xin was like a child who got a new toy, and couldn't help but want to use it first.

"Okay, I'll go back first, I'm really hungry." Lin Zhenhua waved to Yang Xin and left.He didn't have to worry about whether it was safe for Yang Xin to leave work too late. There were also night shift workers in other workshops, and there were militias patrolling the factory area, so there was no problem with law and order.

The next morning, as usual, Lin Zhenhua walked into the workshop stepping on the ringing of the work bell, but saw that everyone was looking at him strangely.Subconsciously, he reached out and touched his face, thinking that there was engine oil on his face, or a lipstick mark or something.

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

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

"No?" Lin Zhenhua himself was not sure.

"Early this morning, Director Luo has been looking for you three times in the moving class. 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 was talking about refers to the director of the metalworking workshop Luo Qinsheng is an old lathe worker with more than 20 years of experience.

For some reason, Lin Zhenhua came to the workshop director's office anxiously. As soon as he entered the door, he saw Luo Qinsheng and several other workers studying a gear. Among them was Peng Gang, the milling supervisor, the best milling worker in the entire Hanhua Machinery Factory. , 47 years old, went to junior high school, proficient in the operation of various types of milling machines.

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

"Xiao Lin, come here, that's right, I'm the one looking for you." Luo Qinsheng said, and Lin Zhenhua could tell from his tone that it didn't seem to be a bad thing.

"Director Luo, what's the matter?"

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

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

"That's right!" Luo Qinsheng patted his thigh, "Xiao Lin, do you know how many gears Yang Xin processed last night? A total of 250 gears, which is equivalent to the workload of one of our master craftsmen in a week."

Peng Gang added: "I didn't believe it at first, thinking she was cutting corners, but I took a dozen calipers to measure, and all of them passed, and it was as if they were milled in the same pass, with no difference at all."

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

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

Lin Zhenhua knew that this matter must be hidden from others, so he nodded and said: "That's right, but well, I didn't design this gear hobbing machine alone. Master Hu Yang from the foundry workshop also participated in the design."

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

No way?Lin Zhenhua secretly called Qu, Hu Yang is a genius, and I, Lin Zhenhua, am not a fool. I said that Hu Yang participated in the design, just to be humble. You can't put all my credit on Hu Yang.

"Uh, this hobbing machine is mainly because I saw others doing it when I was in the army, and then I imitated it. Master Hu also gave me some advice." Lin Zhenhua said.

Luo Qinsheng nodded again and again: "I understand, I understand. Xiao Lin, what you did is really great. We are currently very busy with processing tasks, and the gear hobbing machine you designed solved the problem of gear processing at once. We can free up other millers for other tasks. You are our hero."

"This is what I should do." Lin Zhenhua said.

"It's not easy. Xiao Lin, if you take the initiative to innovate technology like you, we plan to report it to the factory department, and the factory department will definitely reward you."

"Is there a reward?" Lin Zhenhua said with a golden light in front of his eyes, "Director Luo, do you mean that there is a reward?"

"Of course!" Luo Qinsheng said, "Now Vice Chairman Ye advocates scientific and technological breakthroughs, and our factory has also set up a technological innovation award. The gear hobbing machine you invented now will definitely win the award. As for the bonus..."

"The first prize is three yuan." Peng Gang said. When he said this, his eyes shone brightly, as if he saw three one-yuan bills floating in front of his eyes.The eldest son of Peng Gang's family is preparing to get married, and the family's financial situation is very tight. Three yuan is very tempting for him.

"Three yuan?" At that moment, Lin Zhenhua just wanted to put the head of the factory manager on the gear hobbing machine and cut a few knives, so that he could open his mind.His design has increased the production efficiency by ten times, which is equivalent to saving dozens of man-days of work, and the bonus is only three yuan!

Luo Qinsheng didn't notice Lin Zhenhua's disappointment. He felt that three yuan was a pretty good sum of money. At the end of each month, the workers would quarrel upside down over the matter of reducing overtime pay by fifty cents. Lin Zhenhua was a small Young worker, aren't you overjoyed to get a bonus of three yuan?He said to Lin Zhenhua: "Xiao Lin, don't worry, I will definitely win you a first prize. However, have you worked hard these two days, and then make us two sets of gear hobbing machines and install them on other milling machines."
