On the white overalls, a touch of color belonging to the "red flag" is bright and vibrant; the focused expression under the black-rimmed glasses is the appearance that he is most familiar with his co-workers.
Wang Zhi, winner of the 2022 National May Day Labor Medal, the head of the CNC team of the Trial Production Institute of China FAW R&D Institute, the chief skill master of FAW Group, and a CNC craftsman who creates China's "heart" for the Hongqi brand.
China Skills Award, Outstanding Communist Party Member of Central Enterprises, National Technical Expert, Model Worker of Jilin Province... In the 23 years since his service, Wang Zhi has won 74 various honors. But what he is most obsessed with is still the trial production of domestic independent engines, listening to its first roar, and experiencing the moment when his mood resonates with the "heart" of the car...
"We must have our own core technology"
In 2008, at the age of 30, Wang Zhi was selected to participate in the trial production of a V-type 12-cylinder engine. It is the first self-developed top passenger car engine in mainland China, which will be used for the Hongqi parade car for the 60th anniversary of the National Day.
During the trial production process, Wang Zhi successively solved a number of technical problems such as cylinder head combustion chamber error, ultra-fine oblique long hole processing, cylinder body spindle hole accuracy control, camshaft hole coaxial degree error control, etc., refined 12 operation methods, and completed the task excellently.
On National Day in 2009, the Red Flag parade car appeared in Tiananmen Square, and Wang Zhi and his co-workers who watched the live broadcast had red eyes. The engines they process have filled the gap in the manufacture of domestic V-engines, so that the Hongqi parade car has a Chinese "heart".
"We must have our own core technology!" Since then, Wang Zhi has competed with one "difficult problem" after another.
In the trial production and processing of engine crankshaft, Wang Zhi continued to explore and debug, defined more than 300 technical parameters, designed 42 kinds of fixtures, and mastered the key technologies and methods of crankshaft processing technology;
In terms of the design of knife volume auxiliary clamps, Wang Zhi has designed more than 200 sets of special tooling and more than 200 modified tools. He designed the guiding wall fixture and the sub-guidance processing method, which successfully solved the processing problem of the long shaft hole of the first longitudinal double-clutch transmission shell in China;
He led the team to complete the trial production task of the first V-type 8-cylinder direct injection supercharged engine in China, and Phi Xing Dai Yue compressed the trial production cycle of the first finished engine to 30 days;
He completed the trial production and processing task of ice knives in the snowmobile project of the Beijing Winter Olympics, and helped achieve a breakthrough of "zero" domestic snowmobiles;
In recent years, he has participated in the independent processing of core components such as GB, V6, V8 and other more than 20 engines, DCT full range transmissions, new energy reducers, passenger car trans axles and so on.
So far, Wang Zhi has overcome more than 90 key research projects and solved more than 260 technical problems, providing a strong guarantee for independent cars to beat China's "heart" and the rise of national automobile brands.
"Frontline workers can also develop their own software"
Wang Zhi's growth experience has constantly subverted people's traditional definitions and imaginations of workers' images.
"How to 'refine' into a model craftsman, we can learn a lot from the master." Wang Zhi's apprentice Yang Yongxiu said.
Using a lot of spare time, Wang Zhi learned to study CNC processing technology, consult domestic and foreign materials, self-taught computer programming knowledge, and also obtained a self-examination undergraduate degree.
After years of accumulation, Wang Zhi has mastered the operation and programming of the three mainstream CNC systems, and successfully developed more than 100 Fanuc and Siemens system macro program instructions. He developed the gun drilling drilling cycle instruction to avoid the problem of gun drilling breaking caused by traditional manual programming; the horizontal machining center table rotation coordinate system correction instruction developed by him was successfully applied in multi-angle surface processing, and the processing efficiency was increased by 300%, and won the silver medal of the National Invention Exhibition.
"Front-line workers can also develop autonomous software", what Wang Zhi did, refreshed many people's cognition.
In order to continuously improve the skill level, Wang Zhi taught himself CAD/CAM software, established a 3D model of CNC equipment through surveying and mapping, wrote and developed machine tool simulation drive parameter files, and realized the dynamic simulation processing and collision detection functions of machine tools;
He edited and developed the post-file of the five-axis equipment, realized the seamless connection between the programming output format and the numerical control system, and developed the CAM software machine tool dynamic simulation and post-program project, which won the "First Prize of China FAW Innovation Achievement";
He also proposed the "method of automatic programming of two-dimensional shell parts", which has been successfully applied to the processing of multiple product housings.
Relying on the enterprising spirit of never stopping, in the 2013 Sino-US International CNC Skills Competition, Wang Zhi relied on years of experience in editing macro program instructions to ensure that the specimen size was qualified for one-time processing, not only won gold in one fell swoop, but also won the silver medal for fixture manufacturing, and won the honor for Chinese workers.
"Talent promotes innovation, innovation achieves talent"
After learning that he won the National May Day Labor Medal, Wang Zhi told reporters: "This is not only my personal honor, but also thanks to the development platform built by FAW for industrial workers and the cultivation of me for many years." At the same time, I also have more responsibilities, not only to continue to improve the technical level, but also to set an example in promoting the spirit of labor models, the spirit of labor, and the spirit of craftsmen. ”
Wang Zhi has always paid attention to the growth of industrial workers, and he often gives a sentence to young workers: "Those who have established great things in the past will not only have supernatural talents, but also have the will to persevere." ”
In the years of work experience, Wang Zhi has trained 13 senior technicians, led the CNC team to win 15 team honors such as "National Youth Civilization", "Jilin Province Youth Civilization", "Changchun Workers Pioneer", "Changchun Machinery Manufacturing Excellent Team", and the team members have won more than 200 various honors, of which 3 enjoy the special government allowance of the State Council, 2 have won the title of national technical expert, and 4 have won the May Day Labor Medal of Jilin Province.
"Driven by Wang Zhi, the CNC class is all experts." Sun Yongcai, director of the workshop, told reporters that over the years, the "Wang Zhi National Skill Master Studio" has developed 43 training courses, with a total of more than 1,600 people trained, cultivated a number of "multi-gangtong", and won many awards in national, provincial and municipal skill competitions.
So far, Wang Zhi has successively served as the high-skill inheritor of China FAW Model Workers, the vice chairman of the machine plus major of China FAW Youth Science and Technology Association, the high-skilled talent instructor of Changchun Federation of Trade Unions, the visiting professor of Changchun Automobile Industry College and Jilin Industrial Technician College, etc., and has continuously exerted his own advantages to help the construction of high-skilled talent team.
Wang Zhi said that industrial workers in the new era should not only hone their skills, but also be keen on innovation, "talent promotes innovation, and innovation can also achieve talents." China is moving from a manufacturing power to a manufacturing power, we must bear in mind the entrustment, master the key core technologies, and become the backbone of innovation-driven development. ”
