Countercurrent 1982

Chapter 16
"You are..." After Han Zhong took the blueprint handed over by Duan Yun, he glanced at the dim light at the door of the workshop, and then said, "...Do you want to modify our lathe!?"

"Master Han, you are really amazing, you can see that." Duan Yun was surprised when he heard this.

Duan Yun never thought that his master, Han Zhong, could see the content of the drawing he drew at a glance. You must know that when Duan Yun drew this drawing, he did not have any drawing tools such as a compass ruler. The sketch of Zhang's conception is just the specifications and dimensions of some parts on it.

From this, it can be seen that this old guy is indeed a master of retirement and re-employment, and there is indeed a lot of things in his stomach.

"...modulus m=3mm, number of teeth Z1=21, Z2=66, pressure angle 20°, isn't this the standard spur gear below the headstock of our lathe?" Han Zhong held his reading glasses with his hand. , continued to look at it for a while, and asked, "I haven't seen the slip gear you painted on it. It doesn't seem to be the model of our lathe, right?"

"This slip gear is actually a modification point that I want to add to the gearbox." Duan Yun pointed at the drawing and continued: "I added timing pulleys, timing belts, and L-shapes to the original console. Motor base and low-power motor... The L-shaped motor base is installed on the workbench, and the low-power motor is connected to the motor base through a nut. The connection and transmission between the low-power motor shaft and the rotating shaft of the indexing plate are realized by synchronous pulleys and synchronous belts …”

Duan Yun said his general thoughts in one breath, and Han Zhong's face became more and more surprised at this time.

"Where did you see this technique, kid?" Han Zhong finally couldn't help but ask.

Although Han Zhong is very familiar with the structural principles and operation of lathes, he still cannot fully understand the entire structure of Duan Yun's modified machine tools with his mind and experience, but in any case, someone who can make such mechanical improvements is definitely a master!

"I'm in a science and technology newspaper, the "Machinist" monthly!" Duan Yun raised his brows and said.

Duan Yun can show some skills, but he can't be too evil. Moreover, even if Duan Yun said that it was a technical improvement plan that he had thought of, Han Zhong would definitely not believe it, so he simply prevaricates.

"I've ordered "Mechanical Worker" for seven or eight years. I haven't seen any technical articles on the modification of our lathes?" Han Zhong was even more puzzled after hearing this.

"Anyway, I saw it in a magazine, and I forgot which book it was." Duan Yun didn't want to tangle with Han Zhong about this, and immediately changed the subject: "Master Han, I want to find someone to process this picture. A few parts, but I'm not familiar with those old masters..."

"Duan Yun, I'm going to tell you the ugly thing in front of you. This equipment transformation is not something that can be done in a hurry. The machine is an important state-owned asset, even if it is an old machine that is about to be scrapped! If it is accidentally damaged For machines, the lighter ones will be punished by the factory, and the more severe ones will be sentenced!" Han Zhong said with a frown, he obviously didn't have much confidence in Duan Yun's technical reform plan, he just pondered and said, "Either That's good, I'll tell the workshop director Wang when I take over in the morning..."

"Master, if we wait for the approval of the factory leaders, then we will have to wait until the year of the monkey and the month of the horse." Duan Yun pouted and continued: "Master, don't worry, my technical transformation plan is very safe, and the modification part can be done. If it is disassembled from the lathe at any time, it is unsuccessful. At most, a few cutter heads and raw materials are scrapped, and they can be restored to their original state at any time. If the factory needs to lose money, I will pay for it myself!"

Duan Yun had worked in a state-owned factory in his previous life, and he was well aware of the urgency of these state-owned enterprise leaders.

At the beginning, he proposed a technical transformation plan and reported it to the factory leaders, but in the end, it was nowhere to be found, so he did not believe that the master's technical transformation proposal could be passed.

After all, approving the technical transformation plan is a risk for any factory leader. Once the technical transformation fails, the machine is damaged, and the first responsible person is the leader in charge of approval. Besides, Duan Yun is only an apprentice now, and even the technician No, what leader would dare to approve a technical transformation plan submitted by an apprentice?
"Are you really sure?" Hearing Duan Yun's words, Han Zhong hesitated.

After all, he still felt that it was a bit outrageous for a young apprentice like Duan Yun to engage in technical transformation. After all, he, an old worker who had worked as a lathe for a lifetime, still did not have such attainments and abilities.

"Master, I made a rough calculation. If the technical transformation is successful, our work efficiency will be at least five or six times higher than it is now!" Duan Yun paused, and then said: "Isn't the factory paying bonuses on a piece basis? The teacher and the apprentice share the bonus equally, so that's not a small amount of money."

Duan Yun knew that if he couldn't win the support of his master Han Zhong, it would be very difficult for him to make technical changes. After all, Duan Yun had just arrived at this factory and had no connections, and he was even qualified to operate a lathe by himself. No, so trying to bypass Han Zhong to do this is obviously unrealistic.

For grassroots workers, it is nonsense to talk about ideals and love the factory and patriotism and contribute to the country these days, and people of Han Zhong's age have long understood that only wages and bonuses are what they care about most, so Duan Yun also simply proposed the bait of dividing the bonus equally, in order to win over Han Zhong.

"Are you making cakes for me, kid?" Han Zhong smiled when he heard the words, but frowned quickly and said, "I'm worried in case..."

"Master, you can help me with guidance. Let's debug one component at a time. As long as we are careful, we won't be able to get out of the big basket." Duan Yun tried his best to dispel the master's doubts.

"How much cigarettes do you have in your pocket?" After thinking for a while, Han Zhong suddenly asked.

"This box of phoenix belongs to you, Master Xiaojing." Duan Yun heard the words and quickly took out the box of phoenix cigarettes he had just unpacked from his pocket, stuffed it into Han Zhong's tool pocket with a smile on his face, and patted his trousers pocket again. , said: "Master, I still have a box of big front doors here..."

"Hahaha!" Han Zhong laughed when he heard this, patted Duan Yun's shoulder a moment later and said, "Everyone in the factory says you're a fool, but I think you're a genius! Come with me, I'll lead you To get to know a few old masters in the factory."

"Hey!" Duan Yun's eyes lit up when he heard the words, knowing that today's event had come to pass.

Throwing away the cigarette butts in the book, Han Zhong led Duan Yun back into the workshop.

The master's outing is really extraordinary.

Han Zhong, as an old master who has worked in the factory for decades, is quite respected up and down the factory.

The old man's popularity is good. Basically, the older workers in the factory are not familiar with him.

Han Zhong first led Duan Yun to the mold class.

Car tongs riveted and forged electric die.

The mold team mainly uses wood to make models of pouring parts, and the mold team of Hongxing Gear Factory is basically all wood molders.

Molders are still very popular these days. Whenever there are workers in the factory who make furniture, they will ask molders to help. Because the factory wood molds require high precision, the craftsmanship of some molders is beyond the reach of many old carpenters.

Of course, even if it is a factory, it will cost money to find a molder to help make furniture, but the price is cheaper than that of ordinary woodworkers.

Seeing Han Zhong appear, Jing Dajiang, the monitor of the mold class, immediately greeted him with a smile.

"This is my apprentice Duan Yun, I will take care of it later..." Han Zhong introduced.

"Hello, Master Jing." Seeing Han Zhong winking at himself, Duan Yun immediately took out a large front door from his trouser pocket and handed it over with a smile on his face.

"You apprentice is quite sensible..." After taking the cigarette, Jing Dajiang looked at Duan Yun.

"Xiaojing, my apprentice wants to make a few parts today, please do me a favor." Han Zhong said to Jing Dajiang with a smile.

"It's easy to talk!" After Jing Dajiang glanced down at the cigarette brand that Duan Yun handed over, a smile appeared on his face.

Seeing this, Duan Yun immediately took out a match and lit a cigarette for Jing Dajiang, and at the same time handed over the drawings of his parts.

"Xiao Zhang, make these pieces according to the blueprint, urgently needed!" Jing Dajiang turned around and handed the blueprint to several of his apprentices.

A few young apprentices were obviously in awe of Jing Dajiang, so they took out their carving knives and started work without saying a word.

After chatting with Jing Dajiang for a while, Han Zhong left the moulding class and led him to the foundry workshop.

Before the mold was made, Han Zhong led Duan Yun here to say hello to acquaintances in advance, and by the way, let Duan Yun and the masters of these workshops get to know each other well, so as to facilitate future work.

After leaving the foundry workshop, Han Zhong led Duan Yun to several other workshops.

In the end, there were only two big front doors left in the box, but Duan Yun's heart was full of joy.

Taking advantage of the master's face, Duan Yun is considered to have taken the first step in the human relationship in the factory, which is very important to Duan Yun's future plans.

No one can do everything without asking for help, even if Duan Yun has a belly full of knowledge, he can't do everything alone.

The sky was getting brighter, and the two masters and apprentices returned to their workstations.

"It will take two days to make things. If there is such a thing in the future, you can directly find those masters in my name." Han Zhong started the lathe and planned to make a few more workpieces before leaving get off work.

"Thanks to the master today..." Duan Yun said gratefully.

"I'm your master anyway, and it's only right and proper for you to help you." Han Zhong disagreed, and continued, "But you need to master your turning skills as soon as possible. I may be leaving after a while."

"Huh?" Duan Yun was stunned when he heard the words, and then asked, "Master, what do you mean by that?"

"It doesn't make any sense, as long as you can get on top, I won't join this class."

"But……"

"I have enough money for retirement and enough sleep. When I agreed to re-employment, it was also to give Secretary Zhao a face, in order to allow him to arrange a job for my daughter-in-law in a large group." Han Zhong paused, then continued: " If I can nurture you, my friendship will be over..."
