"What are you ......" After Han Zhong took the drawing handed by Duan Yun, he glanced at it under the faint light at the door of the workshop, and then said, "...... Do you want to modify our lathe!?"

"Master Han, you are really powerful, you can see this. Duan Yun looked surprised when he heard this.

Duan Yun definitely didn't expect that his master Han Zhong would be able to see the content of this drawing he drew at a glance, you must know that when Duan Yun painted this drawing, there were no drawing tools such as a compass ruler, this was at best a sketch of an idea, but there were some more specifications and sizes of parts on it.

It can be seen that this old guy is worthy of being a master of retirement and rehiring, and he does have 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 under the headstock of our lathe?" Han Zhong held his reading glasses with his hand, continued to look at them for a while, and asked: "Why haven't I seen the slip gear you drew on it, it doesn't seem to be the model of our lathe?"

"This skid gear is actually a modification point that I want to add to the gearbox. Duan Yun pointed at the drawing with his finger and continued: "On the basis of the original operating table, I have added synchronous pulleys, synchronous belts, L-shaped motor seats and servo motors...... The L-shaped motor base is installed on the workbench, and the servo motor is connected to the motor base by a nut. The servo motor shaft and the indexing plate rotating shaft are connected and driven 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 kid get this technique?" Han Zhong finally couldn't help but ask.

Although Han Zhong is very familiar with the construction principle and operation of the lathe, he still can't fully understand the entire structure of Duan Yun's modified machine tool with his mind and experience, but in any case, the person who can make such mechanical improvements is definitely a master!

"I'm in a science and technology newspaper, it's the monthly magazine "Mechanical Worker"!" Duan Yun said with a raised eyebrow.

Duan Yun can show some skills, but he can't show too demonic, and even if Duan Yun said that it was the technical transformation plan he thought of, Han Zhong would definitely not believe it, so he simply prevaricated.

"I've been ordering "Mechanical Worker" for seven or eight years, and I haven't seen any technical articles on it about our lathe modification?" Han Zhong was even more puzzled when he heard this.

"I just saw it in a magazine anyway, and I forgot about the book. Duan Yun didn't want to dwell on this issue with Han Zhong, so he immediately changed the topic: "Master Han, I want to find someone to process a few parts on this picture, but I am not familiar with those masters......

"Duan Yun, I want to talk to you about the ugly things in the front, this equipment transformation is not something that can be done with a hot mind, the machine is an important state-owned asset, even if this is an old machine that is about to be scrapped! If you accidentally damage the machine, you will be punished by the factory, and you will be sentenced to prison!" Han Zhong frowned and said, he obviously didn't have much confidence in Duan Yun's technical transformation plan, so he only heard him groan and said: "Either this is good, and I will say ...... to Director Wang of the workshop when I take over in the morning."

"Master, if you wait for the approval of the factory leaders, then I don't know if you have to wait until the Year of the Monkey. Duan Yun pursed his lips, and then said: "Master, don't worry, my technical transformation plan is very safe, the modified part can be disassembled from the lathe at any time, but it is unsuccessful, at most a few cutter heads and raw materials can be scrapped, and they can be restored to their original state at any time, if the factory needs to lose money, I will pay out of my own pocket!"

Duan Yun had been mixed in state-owned factories in his previous life, and he knew the urine nature of these state-owned enterprise leaders.

At the beginning, he had proposed a technical transformation plan and reported it to the factory leaders, but in the end it was all lost, so he didn't believe that the master's technical transformation proposal could be passed.

After all, the approval of the technical transformation plan for any factory leader, that is to bear the risk, once the technical transformation fails and the machine is damaged, the first responsible person is the leader responsible for approval, and Duan Yun is now just an apprentice, not even a technician, which leader dares to approve the technical transformation plan submitted by an apprentice?

"Are you really sure?" Hearing Duan Yun's words, Han Zhong hesitated.

In the final analysis, he still felt that it was a bit outrageous for a small apprentice like Duan Yun to engage in technical transformation, after all, he, an old worker who had worked as a lathe worker all his life, still did not have this attainment and ability.

"Master, I roughly calculated, if the technical transformation is successful, our work efficiency will be at least five or six times higher than now!" Duan Yun paused, and then said: "Isn't the factory giving bonuses on a piecework basis now, and when the time comes, our master and apprentice will share the bonus equally, which is 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, after all, Duan Yun had just arrived in this factory, it didn't matter if he didn't have connections, and he didn't even have the qualifications to operate the lathe himself, so it was obviously unrealistic to want to bypass Han Zhong to do this.

As for grassroots workers, it is nonsense to talk about ideals and patriotic contributions to the factory in these years, and people of Han Zhong's age have long understood that only wages and bonuses are the things they are most concerned about, so Duan Yun simply proposed the bait of equal sharing of bonuses, in order to win over Han Zhong.

"You kid are painting cakes for me?" Han Zhong smiled when he heard this, but quickly frowned and said, "I'm worried about what happens ......"

"Master, you can help me guide me at that time, let's debug one component at a time, as long as you are cautious, you can't get out of the big basket." Duan Yun tried his best to dispel his master's doubts.

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

"This box of phoenixes is a filial honor to you, master. When Duan Yun heard this, he hurriedly took out the box of phoenix cigarettes that he had just unpacked from his pocket, stuffed them into Han Zhong's overalls pocket with a smile on his face, patted his trouser pocket again, and said, "Master, I still have a box of big front door ...... here."

"Hahaha!" Han Zhong laughed when he heard this, and patted Duan Yun on the shoulder after a moment and said: "Everyone in the factory says that you kid is a fool, I think you are simply a good person! ”

"Hey!" Duan Yun's eyes lit up when he heard this, knowing that today's matter was done.

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

The old master is really extraordinary.

As a master who has worked in the factory for decades, Han Zhong is still relatively respected up and down in this factory.

The old man's popularity is good, and basically there are no older workers in the factory who are not familiar with him.

Han Zhong led Duan Yun to the mold class first.

Pliers riveted forging electric molds.

The mold team is mainly made of wood to make the model of the pouring parts, and the mold team of the Red Star Gear Factory is basically all wood mold workers.

The mold workers in this year are still quite popular, but where there are factory workers to make furniture, will ask the mold workers to help, because the factory wood mold requires high precision, so some of the mold master skills are beyond the reach of many old carpenters.

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

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

"This is my apprentice Duan Yun, take care of it more in the future......" Han Zhong introduced.

"Master Jing is good. Seeing Han Zhong give him a look, Duan Yun immediately took out a large front door from his trouser pocket and handed it over with a smile on his face.

"Your apprentice is quite sensible......" Taking the cigarette, Jing Dajiang looked at Duan Yun.

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

"It's easy to say!" Jing Dajiang looked down at the cigarette brand that Duan Yun handed over, and a smile suddenly 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 drawings, use them urgently!" Jing Dajiang turned his head and handed over the drawings to a few of his apprentices.

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

After chatting with Jing Dajiang, Han Zhong left the mold class and led him to the casting workshop again.

Before the mold was made, Han Zhong led Duan Yun here to say hello to his acquaintances in advance, and by the way, let Duan Yun be familiar with the masters in these workshops, so that it would be convenient for him to do things in the future.

Out of the casting workshop, Han Zhong led Duan Yun to several other workshops for a turn.

In the end, there were only two big front doors left in his pocket, but Duan Yun's heart blossomed.

With the face of the master, Duan Yun can be regarded as taking the first step in the relationship in the factory, which is very important for Duan Yun's future plans.

No one can do everything without asking for help, even if Duan Yun has a full stomach of knowledge, it is impossible to do everything alone.

As the sky grew brighter, the master and apprentice returned to their workstations.

"It's going to take two days to make things, and if there is such a thing in the future, you can just find those masters in my name." Han Zhong started the lathe and planned to make a few more workpieces before getting off work.

"Thanks to the master today...... Duan Yun said with a grateful face.

"I'm your master, and it's only natural to help you. Han Zhong was a little disapproving, and then said: "But you have to master this lathe skill as soon as possible, I may have to leave after a while." ”

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

"It's not interesting, it's just that as long as you can get on top, I won't be in this class. ”

"But ......"

"I retired with enough money to spend and sleep enough, and I agreed to re-hire at the beginning, which was also to give Secretary Zhao a face, in order for him to arrange a job for my daughter-in-law in the big collective. Han Zhong paused, and then said, "If I can cultivate you, my favor will be over......
