According to related reports,
Xu Liping is a solid rocket motor grain forming machine of China Aerospace Science and Technology Group 74 16 Factory. Also called gunpowder? Sculptor? . This job is one of the most dangerous jobs in this factory.
When it comes to gunpowder carving, people will have questions: Does gunpowder even need carving? However, it is true. It is understood that gunpowder carving is a worldwide problem that cannot be replaced by machines so far in the world. In order to accurately achieve the size and accuracy of the combustion surface of engine propellant, this work must be done by hand. It can be seen that this work is extremely dangerous and demanding. In recent years, China's space industry has developed so rapidly that workers like Mr. Xu Liping have made great contributions to it.
Mr. Xu Liping was born in 1968, and he is over half a year old this year. He devoted his life to the development of the aerospace industry. In the special field of national defense work, I think, why? Gunpowder sculptor? Its name is worthy of the name. Powder carving is one of the most dangerous jobs in the world. Choosing the position of powder shaping is actually equivalent to choosing to be with death. In the process of gunpowder carving, it is surrounded by strong gunpowder. And the whole process needs to be carried out in a powder keg. If the operation is a little careless. Even a little static electricity on clothes. Or a small lump. Will put out the flames. The operator will blow it up.
In addition, it is understood that according to international standards, the error range of powder cutting should not exceed 0.5mm. If there is a slight gap, Xu Liping may be one step closer to death.
However, Mr. Xu Liping has kept the error within 0.2 mm throughout his career. It can be seen that he has extremely high requirements for his skill memory. And he himself is highly skilled.
In addition, it is understood that Mr. Xu Liping has not only persisted in this dangerous industry for more than 30 years. Moreover, I also invented more than 20 kinds of powder shaping tools, and obtained national patents, which saved a lot of time and cost for domestic powder carving. On 20 15, Mr. Xu Liping was awarded the honorary title of Top Ten People who moved China by China.
The craftsmen of big countries are trapped between themselves and danger only for the benefit of the people. For the rejuvenation of the Chinese nation and the vigorous development of the motherland. Mr. Xu Liping bravely advanced in danger. After 26 years of death, he deserves our respect and admiration.
