The picture shows Xu Liping (first from right) and his family as a teenager. 1987 When she joined the work, at the suggestion of her mother, she chose the engine powder molding workshop where her mother used to work to micro-mold the propellant of the missile solid fuel engine.
Solid fuel engine is the heart of missile equipment. In thousands of manufacturing processes, micro-forming of solid fuel engines is very important. Powder molding has always been a difficult problem all over the world, and machines can't completely replace it. Using a knife on gunpowder, a slight careless spark may cause combustion and explosion. Less than 20 people in China are qualified for this extremely dangerous job.
My mother knows the importance and danger of this job better than anyone else, but she said, "When I first started working, some colleagues burned off their whole fingers, and they were all willing to go to the most dangerous positions. I think their young people are the same. "
In this way, Xu Liping began his nearly 30-year work of shaping the powder surface of the engine.
In the second year after work, there was a problem with a key engine in China, so it was very difficult and dangerous to peel off the charged powder. Xu Liping joined the commando team with superb skills and courage. "It can be said that this is the first time in the history of our factory to drill into the powder pile to dig medicine." Xu Liping said.
In the engine shell full of gunpowder, only one operator was left lying and kneeling, digging medicine very carefully with wooden shovel and copper shovel, and only four or five grams could be dug at a time. High tension and lack of oxygen make people work for more than ten minutes at a time. "In addition to the rustling of shoveling medicine, I can hear my heartbeat." Xu Liping recalled. Finally, after more than two months of intense work, Xu Liping and his colleagues dug up more than 300 kilograms of drugs and successfully eliminated the engine failure.
Xu Liping likes to chat with young people during work breaks and listen to their ideas and some current fashion topics. After nearly 30 years of work, Xu Liping has been sticking to the front line. He said that although the work was dangerous, someone had to do it.
Xu Liping can't remember how many times he has completed such a dangerous task. On September 3rd, 20 15, during the military parade, Xu Liping carved some missile engine powder himself.
"The strength of the knife depends entirely on your own judgment. Whether surface accuracy is qualified or not directly determines the precise range of the missile. The work requires 0.5 mm or 0.2 mm. If we shovel this knife, if the required thickness is not reached, the product may be scrapped. " Xu Liping said that it is not easy to achieve the unity of heart and hand, only through hard work. Now, Xu Liping has learned the unique skill of carving the medicine surface that meets the design requirements by touching. At work, Xu Liping has been constantly pondering and making bold innovations. He designed and invented more than 20 kinds of powder molding tools for different engine powder surfaces, two of which won national patents, and one was named "flat knife" by the company after him.
Among the tools he designed and invented, one was named "flat knife" by his company. The picture shows that Xu Liping is adjusting the handle size of the "flat knife" according to the actual use.
Factory 74 16 is far from Xi 'an, quiet but remote. In the coldest and hottest days, it is very hard in the factory. You must open the door of the "life channel" at work, and you can rely on the electric fan in summer, but you can't do anything about the highly toxic mosquitoes. "Mosquitoes that smell gunpowder are very effective." Xu Liping with a wry smile, but also can't, in winter, a posture for a long time will make your hands numb, can only be baked on the heating, and then pick up the knife.
More often, there are no more than two people in each workshop when working. After putting on protective gear and starting to work, Xu Liping said that he felt that the world and time had stopped, and only heard the rustle of digging medicine and his heartbeat.
In the past 30 years, Xu Liping has been so strict with himself, conscientious, keeping company with the most dangerous gunpowder, looking up to the space dream and carving the craftsman's heart. "Didn't the Prime Minister also say that the craftsman spirit is to do one's own essential work and strive for perfection, but there are not so many lofty things," Xu Liping said modestly. After the Spring Festival, Xu Liping won the 20 15 person of the year in CCTV's Moving China. The acceptance speech praised him like this: "Every time I fall off the knife, I can hear my heartbeat. There can't be a moment on the powder. This is really a close call. Strategic missiles, manned space flight, and every weapon of a big country cannot be separated from you. You are a craftsman, you are a great craftsman. "
