Yang Jingde： Hua Tuo, the ＂Imperial Doctor＂ who devoted his life to the aerospace industry.

CCTV News:Speaking of Hua Tuo, everyone must be familiar with it. It is said that this imperial doctor in the Three Kingdoms period has a wonderful hand to rejuvenate the disease. In the Capital Aerospace Machinery Company under the China Academy of Launch Vehicle Technology, there is also a "doctor Hua Tuo". However, this doctor is not a doctor, but an old technician who repairs machine tools. He is Yang Jingde.

Yang Jingde, born in 1937, is a national senior technician, graduated from Shanghai Aviation Industry School (formerly "East China 250 Technical School"), and is one of the earliest military industry technicians trained in New China. At the age of 18, he was assigned to Nanyuan Aviation Repair Factory, today’s Capital Aerospace Machinery Company, and began to deal with cold machine tools.

Now, Nanyuan Aviation Repair Factory has developed into a base for the batch production and development of missiles and rockets in China. From green to old, Yang Jingde never left. He used his life’s wisdom and years to interpret his persistence in the space dream.

Another kind of "magic doctor": "looking, hearing and asking" to repair machine tools

In the 1950s, China’s space industry was still in its infancy, and the conditions were very difficult. Nanyuan aviation repair shop has only a total of hundreds of equipment, all of which are hand-operated machine tools. Yang Jingde doesn’t even have a desk in her dormitory.

However, Yang Jingde was never afraid of hardships, and especially loved to study hard, seizing every opportunity and time to learn advanced technology. Because of his outstanding performance, he was also sent to learn the maintenance of precision machine tools from Soviet experts. For this reason, he made every effort to cherish this hard-won learning opportunity.

At that time, Yang Jingde, who was very young, was already quite famous in the factory. Years of study and research and tempering on the production line have enabled him to practice a stunt: "looking, smelling, asking and cutting" the equipment like an old Chinese doctor.

The oil on the equipment guide rail is more or less, clear or turbid. Yang Jingde can tell the cause of the fault with his eyes.

He can also "listen" to the fault. A few years ago, a British imported equipment was abnormal. Yang Jingde went to the front of the machine tool, leaned down, listened to the noise of the equipment, and then felt the temperature and rotation frequency of the equipment with his hands. The roar in the workshop was extremely noisy, but it did not affect his judgment at all, and he found the "lesion" in a few times.

What’s more, there is another trick, "sound detection from a distance", which makes everyone have to admire the superb skills of this old technician.

One year, Yang Jingde had just finished gallstone surgery, and one of the equipment in the unit was broken. In order not to affect the production, he walked out of the hospital and went back to the workshop for a day. Until he found the cause of the equipment failure and solved the problem, the young comrades of the rest of the equipment could do it by themselves, and he dragged his tired body home. Who knows that at 9 o’clock in the evening, my colleague called and said that the machine that had just been repaired had broken down again. In desperation, he can only instruct the on-site personnel by telephone remote control: "You put your mobile phone next to the machine and I will listen." He vaguely heard the irregular noise in the roar of the machine.

"You put ‘ Lead screw ’ Clean it and see if there is anything extra. " Yang Jingde said.

After the maintenance master took down the "lead screw", he found that there was indeed something superfluous in it. It was aluminium scrap who wore the ball of the "lead screw", which caused the equipment to malfunction. Clean it and reinstall it. Problem solved!

Lay the foundation for your dream with your aerospace peers.

"On October 1, 1997, I began to enter the stage of re-employment, and the specific work was as follows … …” It can be seen from a yellowed Production Task Record Book that this old technician can retire 19 years ago. At that time, Yang Jingde was famous for his stunts, and many units wanted to hire him. The boss of a company came three times and offered him 5000 yuan a month. One company even said, "The salary is up to you, and you are hired as a consultant, so you don’t have to work."

At that time, the salary of rehiring old experts in the factory was 500 yuan per month. Before retiring, the factory leader only said to Yang Jingde: "The factory can’t live without you." He nodded without hesitation.

"I was trained in the factory. Everything I have is given by the factory. I can’t be ungrateful." Yang Jingde said. Not for fame, not for profit, Yang Jingde is like a rock. This firmness is the infinite loyalty of this old technician to the aerospace industry.

After rehiring, the leader always told Yang Jingde that he didn’t have to come to work every day, so call him if he had any questions. But he is still not at ease, coming every day.

Selfless and earnest attitude, marvelous machine repair technology, Yang Jingde has saved a lot of money and made progress for the factory over the years.

In the summer of 2014, an imported machine tool broke down seriously, and there was no maintenance capacity in China, so it had to return to the country of origin, with a maintenance cost of more than 1.3 million yuan and a cycle of at least 3 months. This is a high-precision machine tool, and no one dares to touch it. Yang Jingde looked at it and said, "It can be repaired!"

As a result, 77-year-old Yang Jingde stooped and got in and out of the equipment every day, sweating and working for 20 days. Finally, the machine tool was repaired with only 150,000 yuan. Yang Jingde not only saved "foreign equipment", but also saved more than one million yuan in maintenance costs for the factory. This shocked the original manufacturers.

In 2015, Yang Jingde was 78 years old. Considering his age, the company leaders were really worried about his physical condition, so they ended their re-employment. However, he is still the same as before, and the unit is responsive and has no words.

The old man who repaired machines walked with the aerospace industry all the way, and every progress of this career condensed his life’s hard work and pursuit. He is a witness and a founder. (Text/Liu Chang)
