Pushing open the door of the automobile painting training room of Shanghai Caoyang Vocational and Technical School, a breath of art came to the face. The ink landscape painting painted on the lid has a far-reaching artistic conception;The delicate tiger head is lifelike, as if it will jump out of the picture at any moment. These vivid car painting works can't help but make people marvel at the artist's exquisite skills.
This is where Chang Chen, the gold medalist of the automobile painting project of the second national vocational skills competition, prepares for training.
Chang Chen was admitted to Shanghai Caoyang Vocational and Technical School in 2019 to study Xi automotive painting. "Although there are only a few steps in the car painting process, every detail is crucial: if the grinding is not up to par, it will affect the thickness of the paintingThe color grading is not up to par, and there is a color difference in the repair point that affects the appearance;If you are not careful, you will lose all your efforts. Chang Chen said.
There is no shortcut to learning Xi skills, only by accumulating and practicing Xi day after day. During his Xi at school, Chang Chen carefully Xi studied every technical operation essential, carefully studied and pondered every material and dye. As soon as he got to his spare time, he went to the training room to practice basic skills such as Xi spray painting, and often stayed in the training room until the early hours of the morning in order to overcome a problem.
At first, Chang Chen always had errors in the painting, and it was difficult to meet the requirements. With a spirit of not admitting defeat, he carefully observed how the excellent master operated, and carefully figured out the technical essentials. With the spirit of being willing to endure hardships, studying diligently, and not admitting defeat, he has cultivated a "hard" skill.
After graduating in 2022, Chang Chen joined Shanghai Yongda Group Co., Ltd. *** and is currently working in the company's 4S store. Thanks to the solid foundation laid in school, he quickly mastered the painting requirements of the 4S shop and began to complete the painting work independently.
In August this year, Chang Chen returned to Shanghai Caoyang Vocational and Technical School to prepare for the second national vocational skills competition. Automotive painting is a competition for painting and repairing damage on automotive workpieces, which is divided into three modules, including color vision testing, door skin spraying, and minor damage repair.
This project requires contestants to be able to polish putty to its pre-damaged state, spray paint to the quality of the original paint, and also need to have color mixing and painting skills, which is very technically demanding. The thickness error of each layer of paint cannot exceed 001 mm and 001 mm is equivalent to one-sixth of the diameter of a hair, and it is necessary to quickly adjust the paint that matches the color of the body within the specified time, which is an extremely test of the player's eyesight and brainpower.
In the training room, I saw Chang Chen slowly putting away the spray gun, staring at the painted paint surface to observe whether the color was uniform. Then, he walked around the door panel, paused, circled three times, and walked out of the spraying station without seeing any flaws. "In my understanding, striving for excellence is the pursuit of excellence, which is to make a little progress every day. He said.
During the spraying process, as long as the hand shakes slightly, the error is far greater than 001 mm. Once the error exceeds this standard, the color of the painted surface will be different from the standard color, and the gloss and texture will change. Car paint is generally sprayed with five to six coats, which magnifies this 001 mm of difficulty.
A complete spraying operation takes about 4 hours, which is a double test of physical strength and perseverance. "To practice accurate spraying skills, you must master the control of the air pressure, air output, and gun speed of the spray gun. Chang Chen said.
In order to walk more steadily, he first added a 10-pound paint can to his arm, and then began to practice Xi. At the end of the day, my arm was sore. When you eat and hold chopsticks, your hands will tremble unconsciously. The 10-pound jar hung for 2 months in the morning. "I hang once a day in the morning, noon, and evening for about 1 hour each time. He said that this unremitting effort has greatly improved his technical level.
Paint mixing can bring out tens of thousands of colors. Chang Chen said that in addition to his own sense of color, it is also very important to practice Xi the day after tomorrow. According to the training plan developed by the coaching team, he practiced Xi 1 hour of color grading every morning, and then began the training process for the day, which lasted 16 to 18 hours a day.
It seems to be boring training, but Chang Chen is willing to do it. "I Xi the three modules of the competition every day and try to do each step well," he said. After a long time, practice makes perfect. ”
Ingenuity creates dreams, and skills light up life. From an ordinary vocational teacher to a champion of the vocational skills competition, Chang Chen spent 5 years. "Opportunities are only for those who are prepared," he said. I must continue to Xi study hard, study hard, and constantly improve my professional skills. Only then, when the opportunity comes, can I seize it and succeed. ”
For the future, Chang Chen has higher goals and expectations. He hopes to participate in the WorldSkills Competition and win glory for the country. (Economic ** reporter Li Zhiguo).
