Labor writes the chapter of the times, and strives to create a better future. The May Day that has just passed is a festival to pay tribute to laborers. This includes skilled workers. "The team of skilled workers is an important foundation to support Made in China and Created in China, and plays an important role in promoting high-quality economic development." Countless high-skilled talents have given full play to their expertise and found their positioning, which has not only made due contributions to the manufacturing power, but also realized their life value and achieved their dreams. Today, we will get to know a few of them and see how they continue to break through in their work, strive for excellence, and practice their unique skills.
In the early morning of April 26, 2024, the Shenzhou-18 manned spacecraft docked with the space station assembly, and the space rendezvous and docking are inseparable from a very critical component, that is, the "docking mechanism".
Wang Shuqun, head of the docking mechanism assembly team of the 149 factory of the Eighth Academy of Aerospace Science and Technology: The docking mechanism used by the Shenzhou spacecraft can realize the flexible connection of the two aircraft at the moment of high-speed flight, and establish a rigid airtight channel between the two vehicles, so that astronauts can work and live in two different cabins without wearing spacesuits.
When the vehicle orbits the earth in space, the speed reaches 7.9 kilometers per second, and when the two vehicles fly at high speed, the docking mechanism can realize the capture, correction and docking between them, providing technical support for the long-term in-orbit operation of the space station.
Wang Shuqun, a special technician of China's aerospace industry, leads the only team in China to assemble and debug a manned space docking mechanism. More than 30 years ago, Wang Shuqun graduated from a technical school and entered the Aerospace Science and Technology Group to work as a skilled worker. When he first entered the factory, Wang Shuqun followed his master and learned various skills such as chiseling, filing, sawing, scribing, and drilling on the fitter table every day. Because he is diligent and studious and likes to study, Wang Shuqun quickly mastered excellent skills and became the backbone of the company's tooling and mold manufacturing.
In 1995, the Eighth Academy of Shanghai Aerospace Science and Technology Group began to set up a docking mechanism research and development team, which was mainly responsible for the development and assembly of docking mechanism parts. As an excellent skilled personnel, Wang Shuqun became a member of the research and development team of the docking mechanism and was responsible for the installation of precision equipment.
Without any technical experience to draw on, it all relied on groping from scratch, and in the absence of reference materials, the R&D team spent two years to make the first prototype of the principle. However, the prototype went to the test bench, and the test results disappointed the R&D team. What's the problem? In the face of tens of thousands of parts and tens of thousands of meters of wires, finding the problem is like looking for a needle in a haystack.
Wang Shuqun, head of the general assembly group of the docking mechanism of the 149 factory of the Eighth Academy of Aerospace Science and Technology: We don't know where the problem is, so we can only try little by little through the stupidest methods, list the various possibilities first, and then try them one by one.
During that period of time, Wang Shuqun was like a demon, experimenting again and again, trial and error again and again, and all he thought about in his mind were formulas, data, and algorithms. After more than a year of hard exploration, in more than 1.5 million data, Wang Shuqun finally found that the slight change in the tension of the control lock wire rope led to the asynchrony of the lock. He quickly came up with a plan to solve the problem of synchronization coordination of the docking lock in one fell swoop.
Wang Shuqun carries a notebook with him every day, and whenever he has new ideas, experiences and lessons, he will write them down in time. Wang Shuqun uses several notebooks like this a year.
From the development of the prototype in 1995 to the formal product acceptance and delivery, this step spanned 16 years for the development team. At 1:36 a.m. on November 3, 2011, the Tiangong-1 target vehicle and the Shenzhou-8 spacecraft successfully completed the first rendezvous and docking. The docking mechanism always performs perfectly in the ultra-difficult maneuvers of threading the needle in space.
With the success of the first rendezvous and docking, Wang Shuqun did not stop, but put into the production and manufacturing of products, he mastered a number of patented technologies, and the declared innovation achievements won the second prize of the National Science and Technology Progress Award. During this period, he completed his college and undergraduate studies and became a representative of knowledge-based industry workers.
In recent years, the construction of high-skilled talents in mainland China has entered the "fast lane". At present, there are more than 60 million high-skilled talents, who are active in all walks of life in the mainland, and some of the products they produce shine in space, contributing to the mainland's aerospace industry, and some products seem to be inconspicuous, but they are closely related to our lives.
Cans can be seen everywhere in our daily life, however, what many people don't know is that for a long time in the past, cans and ring molds could only be imported from abroad at high prices. In Wuxi, Jiangsu Province, a private enterprise successfully developed this mold.
Chen Liang, the former team leader of the machining center of Wuxi Micro Research Co., Ltd.: When pulling the ring, a line mark is embedded in it, and the embedded line mark can not be deep or shallow, too deep to leak and self-detonate, too shallow to pull it, the requirements of the line mark are very high, and the accuracy of the line cutter required by the line mark is higher, and we strive to achieve it within 0 to 2 microns.
Chen Liang, one of the first developers of the first batch of easy-pull ring molds in China, a national model worker and technical expert, is called "micron master" by people in the industry. In 1998, Chen Liang was admitted to a technical school in Wuxi to learn mold design and manufacturing, and after graduation, he entered a private enterprise in Wuxi to work in a mold manufacturing company.
Once, the company received an order for high-precision positioning parts for a TV, requiring the accuracy to be controlled within 2 microns. At that time, traditional tools were mostly used for machining in China, and the accuracy could only reach 4 microns. After many unsuccessful attempts, the masters thought of Chen Liang, who loves to use his brain and can study. Chen Liang broke the conventional thinking and innovatively combined the two originally completely different processes of "milling" and "grinding", and used precision grinding wheels for grinding in machine tool processing.
After continuous attempts, a week later, Chen Liang successfully controlled the accuracy of the product at 1 micron, which was the first time that the accuracy of such products in China reached 1 micron, and it also broke the monopoly of foreign technology. Chen Liang "became famous in a fight", and "Micron Master" was also called.
In recent years, the mainland has continued to carry out the reform of the construction of industrial workers, and built a system for the formation of industrial workers' skills. Chen Liang actively participated in the skills training organized by the trade union, learned and accumulated from the apprentice step by step, insisted on taking the vocational skill level certificate, and successively obtained the qualifications of intermediate worker, senior worker, technician and senior technician.
With the deepening of the reform of the national promotion of the construction of industrial workers, the development space of industrial workers has been further broadened, and the career development channels of high-skilled talents and engineering and technical talents have also been opened. Chen Liang also signed up for the evaluation of the engineer's title. In April 2023, the senior engineer he had been looking forward to was finally assessed.
At the end of 2023, Chen Liang returned to his alma mater to become a teacher, specializing in training a new generation of skilled workers. Over the past seven years, a number of measures have been comprehensively promoted and deepened in all parts of the country and in various industries, benefiting the majority of industrial workers, and the team of high-quality industrial workers has gradually grown. More and more front-line workers, like Chen Liang, have obtained the title of senior engineer with their professional skills. And those who are struggling on the front line of the industry are not only "professors" among workers like Chen Liang, but also professors in the original laboratory who have crossed over to become craftsmen.
In the finals of the 2023 National Employee Digital Application Technology Skills Competition, 46-year-old Chen Zhaochun, with his excellent digital knowledge and welding technology, commanded the robot to weld 8 perfect welds, and finally won the crown of the robot welding competition. Unlike the vast majority of contestants who participated in this robot welding competition, Chen Zhaochun is not a welder, but a standard researcher who stays in the laboratory.
Chen Zhaochun is a senior engineer. In college, he studied mechanical and electronic engineering, after graduation to work in the Institute of Automation of Fuzhou University, a few years later to the Fujian Provincial Special Equipment Inspection and Research Institute, now as the deputy director of the new technology development center of the research institute, the head of the science and technology innovation team, has been engaged in the research and development of industrial robots.
In 2019, Chen Zhaochun went to the welding workshop to learn from a teacher and learn manual welding. A scientific researcher who is more than half a hundred years old does not wait in the laboratory, why does he have to go into the workshop as an "apprentice"?
Chen Zhaochun, deputy director of the new technology development center of Fujian Special Equipment Inspection and Research Institute: special equipment manufacturers, such as in the field of welding, have some difficulties in employment, because the welding environment is relatively harsh, the site temperature is relatively high, and the concentration of toxic and harmful gases is relatively large, which leads to many young people being unwilling to engage. We wondered if there could be an intelligent robot that could replace workers in harsh environments.
The purpose of Chen Zhaochun's apprenticeship is to develop intelligent robots that can replace the work of welding workers, promote the digital transformation of the welding industry, solve the employment difficulties of enterprises, and keep welders away from the working environment of arc radiation, toxic gases, welding fumes and high temperature and high heat.
As a scientific researcher, what Chen Zhaochun has to do is to learn the welding skills of workers in the workshop, and then integrate these technologies into the robot's system. Up to now, Chen Zhaochun has led the team to develop a ground patrol explosion-proof robot and a high-altitude detection wall-climbing robot for the detection of special equipment. Now, they are developing a special robot for welding boiler walls.
Chen Zhaochun said that in the digital era, higher requirements have been put forward for high-skilled talents, and what is needed is "digital craftsmen", that is, compound skilled talents who not only have the level of modern industrial technology skills, but also master intelligent and networked skills, and are good at integrating digital skills to transform and upgrade traditional industries.
Promoting high-quality development and developing new quality productivity are internal requirements and important focuses. The development of new quality productive forces is inseparable from a large number of high-skilled talents, skilled craftsmen, and craftsmen of great powers, and their in-depth study and persistent pursuit in their respective fields. At the beginning of this year, the Ministry of Human Resources and Social Security, together with relevant departments, issued the "Notice on the Implementation of the Cultivation Plan for Highly Skilled Leading Talents", proposing that from 2024 to 2026, mobilize and rely on all aspects of society to focus on cultivating leading talents in advanced manufacturing, modern service industries and other related industries. More and more high-skilled talents will provide strong support for accelerating the development of new quality productivity.
