TV series "Boiled Life"
This is a scene from the TV series "Boiled Life": in the workshop of the Huaqi Factory, the old master Liu with a Shaanbei accent started the lathe with trembling hands. The machining accuracy is very demanding. Harsh bolts. The college students on the side couldn't help but say: "Isn't it a joke that the hands are shaking like this for such precise work?"
Old Master Liu said to his open hands: "Old man, fight for your breath". Afterwards, the clenched hands of old master Liu stopped shaking. He sharpened the knife, applied the knife, stuck the knife, and fed the knife... After turning the bolts out of the thread, he slowed down the speed and used a file on the thread. Refined.
Mr. Liu went to battle
The file was in the process of working
Mr. Liu handed over the processed parts
After finishing the processing, Mr. Liu held the bolt and spit out a word: "measure". Another older master replied, "Brother, I'll come". Later, he reported the measurement results: "The major diameter is 15.868, which is qualified."
Everyone is more concerned about the size of the middle diameter - just because the accuracy of this bolt is not enough, the Huaqi Factory changed from five tons to seven. There was a problem with the suspension of the ton military heavy truck during the test run, which caused the vibration to be difficult to control, and also affected the chassis system and power system.
bolt processing became a difficult problem, the eighth-level worker "Liu Yi file" came out
According to the drawing requirements of the seven-ton truck, these bolts with a diameter of 16 mm must have a major diameter of 15.73 Between 2 and 15.968, the diameter is controlled between 14.854 and 14.994. For this precision, the thread rolling machine tools of Huaqi Factory in the 1950s and 1960s could not meet it, and only the imported German thread rolling machine tools could achieve it.
However, the German thread rolling machine imported by Huaqi Factory failed a few years ago. It was this old master Liu who burned out the circuit during maintenance. The German side cost $50,000 to replace it. The imported thread rolling machine is lying there. The
five-ton truck was changed to a seven-ton truck. The military gave the Huaqi factory only six months, and the time to solve the bolt problem was only three days. How to do? The leaders and employees of the Huaqi Factory brainstormed and decided to walk on two legs. On the one hand, we organized a group of masters and retired masters in the factory to use old machine tools to overcome bolt processing. On the other hand, college students from the factory formed a maintenance team to try to repair the German thread rolling machine.
imported German machine tools were disassembled
The masters took turns taking turns
Production section chief Ai Shaanbei himself did not pass the processing
took three days to repair an imported machine tool, which was obviously not enough time. Everyone first pinned their hopes on the tough battle of bolt processing, but the masters were unfavorable. The large diameter of the processed bolts could meet the requirements, but the middle diameters were not qualified. Ai Shaanbei, the production section chief of
, went into battle in person, and the processed parts were also unqualified. At this time, everyone mentioned the master of the factory director Ge Baozhong and the production section director Ai Shanbei, the old master Liu who is nicknamed "Liu Yibao".
"Liu Yifile" can be said to be a big man in the history of Huaqi Factory. He is proficient in fitters and lathes. With a single file, the parts are more accurate than machine tools. He has represented Huaqi in the National Technical Competition for many times. He is known as the eighth-level worker among the eighth-level workers. He is a major contributor to the development of five-ton heavy trucks by Huaqi.
Everyone talks about "Liu Yi file"
But a few years ago, Mr. Liu was criticized by his apprentice Director Ge for repairing the German thread rolling machine, so he retired early and went home in a fit of rage. Ai Changan, the son of Section Chief Ai and a test driver, volunteered to invite Master Liu and spent two days in front of Master Liu's house.
Mr. Liu finally agreed to come out, on the condition that his apprentices, Factory Manager Ge and Section Chief Ai, apologize to him in the rain tomorrow. On the third day, when Director Ge and Chief Ai stood in front of the old master Liu's house and got wet in the rain, the old master Liu came to the Huaqi Factory and began to stage the scene of processing bolts.
Measuring the pitch diameter of the bolt
Ai Changan shouted "qualified"
College student Xu Chi praised the incredible success
In everyone's attention, the three-needle measurement method to measure the pitch diameter of the bolt began. The inspector wrote down the inspection data with his notes while watching, and took off his mirror to look carefully.Look, then pick up the bolt and announce: "Pitch diameter, 14.925."
Apparently this number is between 14.854 and 14.994, and someone mumbles "It seems to be ", Ai Changan shouted: "Qualified!" Everyone cheered, applauded, and hugged, and the scene was boiling. College student Xu Chi praised: "It was a one-time success, and it fully met the accuracy requirements, it's incredible!". The
master craftsmen have left behind classic works, and they have left with glory.
has shown the extraordinary skills of the master craftsmen more than once in industrial TV dramas. Previously in " Lushan Song ", Lushan Heavy Industry and the world construction machinery manufacturing giant Hipio filed an infringement lawsuit. Matthew, the representative of Hyperion, asserted that Lushan Heavy Industry did not have CNC boring and milling machines ten years ago, and it was impossible to process the ball sockets of precision parts, because the surface roughness of the ball sockets seemed to be lower than 0.01 microns, reaching or even exceeding the mirror surface technology level.
In this regard, Fang Ruizhou, chairman of Lushan Heavy Industry, said: It was processed by our workers through traditional machine tools. This worker is called Song Chunxia.
The TV series "Song of Lushan"
is similar to Liu Yibao in "Boiled Life". Song Chunxia is a national model worker and a machinist, and is now the director of the experimental workshop of Lushan Heavy Industry. In order to prove that the ball socket was processed by a traditional machine tool, Song Chunxia, who was already dazed and trembling, accepted the challenge and went into battle again to process the ball socket.

Hypio's representative Matthew supervised the scene, and turned on the lights and broadcast live with several cameras. Under the heavy interference and pressure, Song Chunxia remained calm in the face of danger, and processed a mirror-level ball socket with a surface roughness of less than or equal to 0.01 microns. There were cheers and applause inside and outside the scene. Song Chunxia won the battle of ball socket processing, allowing Lushan Heavy Industry to take the initiative.
also has Song Chunxia's wife, Ma Daqing, a senior welder in the experimental workshop. His grandfather, father and he are three generations of model workers and master craftsmen of Lushan Heavy Industry. His apprentice, Jin Yanzi, the head of the section of the welding workshop of the sanitation company, brought an urgent letter and asked him to weld. Song Chunxia, who was present at
, said it was too difficult and quit. But Ma Daqing insisted on doing it, although he had never done such a job formally, only practiced in private. As a result, Ma Daqing completed the welding beautifully.
Welder Dana Ma Daqing
showed the superb skills of the master craftsmen in large-scale in TV series such as "Song of the Foothills" and "Boiled Life", and fully praised the craftsman spirit of . At the same time, with the development of the times, with the modernization of enterprises and the upgrading of automation technology, numerical control equipment gradually replaces manual operation, and the master craftsmen can also shift work with peace of mind.
In "Boiled Life", the college students repaired the German thread rolling machine and produced qualified bolts in batches. Master Liu sincerely praised the college students and asked to leave a bolt as a souvenir. He said: "I came for the bolts, and I took the bolts away, and it was complete."
Mr. Liu said that he was successful
In "Song of Lushan", the experimental workshop and the i5 smart workshop merged, a new generation of knowledge workers took over, Song Chunxia and Ma Daqing both retired. Song Chunxia took away the cutter head developed when machining the ball socket and said to Ma Daqing, "No one will use this milling cutter in the future." Ma Daqing took the old face mask his father left him and said to Song Chunxia, "They have their beauty, we have our glory, and our generation of workers has not lived in vain."
