Countercurrent 1982

Chapter 19 Break the record
"Thank you so much, Master." Duan Yun said gratefully.

In fact, I am secretly glad in my heart. After all, it is indeed a crazy thing for an apprentice who has been working in the factory not long to make technical changes. It has to be said that it is a kind of luck, or that this Han Zhong is the first 'noble person' Duan Yun met after his rebirth.

"There's no need to say such words. There are still more than two hours before get off work. Let's test the effect of the modification first." Han Zhong glanced at his watch and said,
"Well." Duan Yun replied, and the two returned to the workshop.

Although Duan Yun has been thinking about this technical renovation plan over and over for the past two days and scrutinized all the details, it should be said that he is still a little confident, but when he really wants to start the test, he still has some indescribable nervousness in his heart. .

"Duan Yun, please check again to see if there is any installation error on the line." Han Zhong was obviously a little worried at this time. Although he said he was ready to take responsibility, he still remained cautious and cautious.

In fact, in Han Zhong's view, this kind of technical improvement is basically difficult to succeed at one time. According to him, even some professional engineers try to improve this kind of technical improvement, and they are all testing and improving, and it is repeated over and over again. It takes a long time to complete the complex, and it is rarely successful in one go.

"There should be no problem." Duan Yun checked the modified parts and wiring again, and said to Han Zhong: "Master, you can start the machine, you should stand farther away."

"Wait!" Han Zhong suddenly shouted.

"What's the matter, master?"

"Give me another cigarette." Han Zhong stretched out his hand and said. .

Han Zhong usually rarely smokes in the workshop, but this time he was obviously a little excited.

Duan Yun said nothing, took out a cigarette and handed it to Han Zhong and lit it with a match.

Then, after Duan Yun was ready, he started the lathe.

"Buzz!"

The moment the power is turned on, the spindle starts to rotate rapidly.

When the main shaft rotates, it drives the polished rod next to it through the bridge gear, the worm on the polished rod drives the worm gear and connects with the longitudinal cam on the worm wheel,...Using the limit switch and electromagnet, the semi-finished column head element placed on the angle iron is quickly pushed against The spring chuck in front of the spindle is fixed, and then the longitudinal tool is fed to the specified position.

The principles and actions of the modification sound a bit complicated, but in fact, this series of actions all happen in one breath.

"prick!"

The sharp metal cutting sound sounded, and the dark blue iron filings rolled down in circles, and the stigma of a rough car was quickly cut.

"Click!"

The lever pushes the transverse turning tool forward, the processed column head part is cut off, the spring clip is released, and the waste material also rolls into the iron box located under the spring clip.

Seeing this scene, Duan Yun and Han Zhong's heart skipped a beat.

The lathe was still in automatic operation, and it was not until the five raw materials on the feeding rack were processed that the expressions of the master and the apprentice began to relax a little.

"Take it over and measure the accuracy." Han Zhong said to Duan Yunan, but immediately reminded: "Use an iron clip, be careful to burn your hands!"

Duan Yun heard the words, took out all the finished products from the iron shell placed under the chuck, and put them on the toolbox next to them.

Han Zhong took out the vernier card from the box. This kind of rough car does not need a micrometer.

After carefully measuring one by one, Han Zhong took two puffs of cigarettes, and a smile appeared on his face.

"No problem, they are all qualified products!"

"Then our remodel is a success, right?" Duan Yun asked with a smile.

"Quality shouldn't be a big problem, we'll have to see how efficient it is." Han Zhong was also excited at this time, glanced at his watch and said, "There are still two hours before get off work. All the materials are placed on the angle iron shelf, let me see how much can be processed in this hour!"

"Yeah." Duan Yun heard the words, and immediately walked to the stocking box at the station, took out the blanks inside, and gently placed them on the angle iron rack for feeding.

Then, the machine starts up again and starts a new round of automatic processing procedures.

One, two, three... The stigma completed with the chips was continuously cut and rolled down from the connection of the chuck head. The speed was so fast that Han Zhong, who had been a turner all his life, couldn't help but sigh.

Generally speaking, even for rough machining of a chuck, an experienced master is required to repeatedly clamp the raw material with the chuck, adjust the coaxiality, and continuously correct the feed rate and the amount of cutting tools during processing, and then pass the color of the iron filings. It is time-consuming and laborious to judge whether the cutting force and cutting temperature are in the normal range, etc.

The automation improvement of Duanyun this time has set everything in advance, saving many tedious steps in manual operation, which undoubtedly greatly improves the processing efficiency of the lathe.

37, 38, 39...

Han Zhong has been silently thinking about the proficiency of the finished product, and when he looked down at the watch on his wrist, less than 10 minutes had passed, he already felt a huge shock in his heart.

Nearly forty parts were processed in 10 minutes, which definitely broke the factory's fastest record!
You know, in the past, Han Zhong used this machine tool to process 91 parts during the normal working time of eight hours at most. At that time, it can be said that he did not stop for a moment.

As for normal times, Han Zhong only processes forty or fifty finished products a day.

But now, this automatic lathe has almost completed his previous workload of nearly a day in less than half an hour. The efficiency is far beyond Han Zhong's imagination!
But at this time, Duan Yun was still a little dissatisfied with this automatic modification.

In his opinion, this automatic lathe still has a lot of room for improvement. If it is changed again, Duan Yun is confident that the efficiency can be at least doubled!

In fact, if it weren't for the fact that this former Soviet lathe was too old and the spindle speed was slow, Duan Yun would have even more room to play!
For the next hour or so, the master and the apprentice quietly observed the operation of the machine.

Time passed quickly, the lathe was always running normally, and the shift time was getting closer and closer. Through the window, you could even see the workers coming to work outside.

132, 133, 134...

Han Zhong's eyes staring at the lathe are already obsessed.

"hiss!"

Feeling a sharp pain in his fingers, Han Zhong flung the cigarette fart in his hand that was about to burn out, and then took his eyes back from the lathe.

"Master, are you alright?" Duan Yun, who was beside him, quickly asked.

"It's okay." Hearing this, Han Zhong shook his head, then turned to pat Duan Yun's shoulder, and said with a smile, "Duan Yun, with this machine, you will be the model worker representative of our factory this year... "
