1In the autumn of 988, 16-year-old Zhang Suli gave up her college dream because of her poor family, and chose to study locksmith in the technical school of Luoyang Locomotive Works in Henan Province. That day, after the training class, the male students in the class will leave. Zhang Suli and other female students stopped male students and wanted to compete with them to cut steel bars with a flat shovel.
Cutting steel bar with a flat shovel is the basic skill of fitter's major, and the operator needs to hold a hammer and hit the flat shovel to cut steel bar. Usually 10 mm steel bar, most boys can cut it within 10 tap, while female students in the class usually need dozens of taps to cut steel bar. So male students often laugh at female students.
Zhang Suli has come to challenge gay learning. The best male student in the class, bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang!
It's Zhang Suli's turn to play. She raised the hammer in her right hand, swung a proper arc in the air and hit it accurately on the flat shovel clenched in her left hand. The left hand covered with blood bubbles holds more tightly under the great impact. One, two, three times, the sound of metal impact echoed in the factory building, and the steel bar was broken. After a short silence, the onlookers applauded warmly.
In just a few seconds, Zhang Suli has been practicing hard for a month.
The victory of the first informal skill competition in her life made Zhang Suli feel that as long as she practiced hard and persisted in never back down, she would be able to practice her unique skills.
This belief has accompanied Zhang Suli on this road for more than 20 years, and accompanied her to win the Chinese Skills Award and the National May 1 Labor Medal, becoming a rare female expert in the industry.
Concentrate on learning skills and make a blockbuster.
In the days of Luoyang Locomotive Factory Technical School, locksmith study is boring for most teenage girls. When others are playing and shopping, Zhang Suli uses her spare time to consult her teacher and practice the basic skills of locksmiths. The blisters on the palm of your hand haven't gone down yet, and new blisters grow the next day after practice. Sometimes she would cry in pain, but she always remembered the teacher's words: "There is no shortcut to learning locksmith. Only by practicing hard, hands, eyes and heart are in place, can you perform unique skills. " Enduring the pain, she picked up tools to practice again. Slowly, the blisters didn't get up; Gradually, a thick cocoon was ground on the palm of your hand.
Zhang Zhenshan, a teenage girl, was deeply impressed by her diligence and self-discipline. He thinks that this child is not simple and will have a future.
As Zhang Suli is in the second grade of technical school, Zhang Zhenshan asked her to give a demonstration to her classmates instead of herself. Zhang Zhenshan helped Zhang Suli analyze and demonstrate whether the work was done well, what were the problems designed by the engineers, what were the operational problems, and how to avoid them next time. Zhang Suli's feel is getting better and better, and her works are getting more and more exquisite.
Soon after, Zhang Suli participated in the national inter-factory technical school technical competition by selecting and representing the school. In the pre-competition training, Zhang Zhenshan thought that Zhang Suli's basic skills and skills were fine, and her only concern was her adaptability on the field. Therefore, Zhang Zhenshan intends to strengthen her anti-pressure ability and anti-interference ability, so that she can concentrate on finishing the race no matter what unexpected situation.
199 1 year, Zhang Suli won the second place in the locksmith project of the national inter-factory technical school technical competition. Upon graduation, she obtained a five-level fitter certificate, and was hired by Luoyang Locomotive Co., Ltd. of China South Locomotive Group with the first place in fitter major.
Zhang Suli worked as a fitter in the bogie workshop and began to draw lines as a fitter. Solid basic skills make her work handy, and one piece of work with accurate and clear lines is handed over to the next process. The technicians praised her for her agility.
Later, she was transferred to the metalworking workshop as a die fitter. This work mainly depends on manual work, from the die handle to the bottom plate, every component needs to be carefully analyzed to find out the function and relationship. Zhang Suli carefully studied each technological process and production, and analyzed the assembly relationship of the mold.
Ding Jie, an engineer and technician who partnered with Zhang Suli in the workshop, said: "She is full of energy and won't give up until she understands a problem."
Zhang Suli borrowed a technical book and found out what she couldn't understand on the technical drawings. If there is a problem in the production process, please ask an experienced technician to help her standardize the operation process. From simple blanking and stamping, to blanking and punching die, to the production of jumping die and thin-walled drawing die, Zhang Suli learned while doing, summarized and improved, and the more dry she was, the more refined she became.
In addition to dealing with technical challenges, Zhang Suli also needs to face physical challenges.
Many molding modules weigh 40 to 50 kilograms. It is very difficult for the average girl to move one, but for her, this kind of thing has to be repeated dozens of times every day.
In the hard work day after day, the students who entered the factory with Zhang Suli tried to change jobs one after another, some to do administration, some to do marketing ... Some female students advised her, why is a girl so tired? How about a more relaxed posture?
But Zhang Suli said: "You beat the mold, and you will make a new mold every day, and you will encounter new problems every time. It is impossible to make one mold at a time. It is this process of repeated thinking and repeated hands-on. It's so fun, it's not bitter at all. "
Zhang Suli's outstanding performance has attracted the attention of the leaders of CSR Luoyang Locomotive Co., Ltd.
1994, the company decided to use 22-year-old Zhang Suli to participate in the South China Film Technology Competition. In the locksmith senior group competition, Zhang Suli is an intermediate worker, and all the players except her are men. At first, no one took the little girl seriously. As soon as the game was over, she was the first, and many male players were not convinced. However, after the game, everyone was convinced when they saw Zhang Suli's works. Zhang Suli has also become the youngest young technician in the factory.
In the years of tempering, Zhang Suli's fitter skills are becoming more and more exquisite, and the manual operation errors are getting smaller and smaller. The workpiece she made can be accurate to 1/4 of the hair.
Ten years of training, heart and hand are one.
Zhang Suli at work
In Ding Jie's eyes, Zhang Suli, the partner of 10, always brings her many surprises. With amazing skills in hand, Zhang Suli can chew down any hard bones.
There has always been a saying in the field of mechanics that "lathe workers are afraid of lathe poles and fitters are afraid of drilling", and drilling has always been a big problem for fitters. However, after studying hard and grinding the drill bit by herself, Zhang Suli can only drill through the top one of the two overlapping A4 papers, but the bottom one is not damaged at all. You can also drill holes in fresh eggs, and the eggshell can be drilled through without damaging the inner membrane.
Zhang Suli's basic filing skills are even more obvious. She can control the machining allowance without measuring. On the same workpiece, she can use files with different strengths and specifications to accurately ensure the dimensional accuracy according to the machining allowance, and the form and position tolerance can be controlled within 0.02 mm ..
"Her hands are even more accurate than machines," praised Li Yong, a company technician.
Only Zhang Suli knows that these unique skills are the result of practicing for tens of thousands of times. In one training, before the bruises on her hands subsided, she put on gloves to practice. But after putting on gloves, the workpiece felt bad, so she simply took off her gloves and continued to do the workpiece.
As Zhang Suli's skills become more and more exquisite, the company requires her to undertake more and more important tasks.
General Electric Company and Northern Glass Company are famous for their strict requirements for products. On one occasion, Zhang Suli was responsible for the fixture of the air dryer bracket. A job requires six sets of molds, such as drilling, welding and milling. One of the technical requirements is that the surface profile should reach 0.3 mm For assembled weldments, the deformation of workpieces will exceed the requirements after welding. However, due to the limitation of workpiece structure, there is no way to weld before milling, only one way is assembly welding. Zhang Suli put forward improvement suggestions to technicians to help welders adjust welding sequence. After repeated debugging and improvement, many things and all the workpieces have passed the inspection.
The products not only satisfied customers, but also won the second prize of the company's science and technology.
Gasket is a small part of a device of Bei Bo Company. It looks ordinary at first glance, but it is very troublesome to make. During machining, it is required to drill a central hole and two oblong notches on a circular pad with a diameter less than 35 mm, and only four skipping punches can be made in the production process. Moreover, every blanking must face the test of strict dimensional tolerance and positioning requirements, just like drawing on an egg skin.
Ordinary locksmiths can punch the first hole in the mold, but it is difficult to control the interval and relationship between the second hole and the first hole. The workers in the company all say that this is an impossible task.
Zhang Suli carefully studied the design drawings, typed out the time and strength of each punch, and then trimmed it with a pair of skillful hands, thus gnawing at this hard bone. The product manager of GE Company was full of praise after seeing the product: "I didn't expect such a skillful craftsman."
Zhang Suli was not satisfied and began to meet new challenges. The wire cutting machine operator in the workshop took maternity leave, and when the wire cutting machine was idle, Zhang Suli began to learn to operate. It is not difficult to operate this machine, but it takes several years of training. Zhang Suli has no teaching materials and no hands-on training. While thinking, she fumbled for the operating instructions of the wire cutting machine. Everyone else is on vacation during May Day, but she gropes for new machines in the factory from morning till night. In the end, she mastered the operation skills of wire cutting machine in 7 days.
Because of Zhang Suli's outstanding performance, in late May 2003, the company asked her to participate in the second vocational skills competition of China South Locomotive. After training during the day, Zhang Suli came home at night and took out books to learn theoretical knowledge. When the child was less than two years old, she read books and took care of the child.
In a preparation for the exam, Zhang Suli did a small homework because of a small mistake. After discovering it, she made great efforts to make it up and almost failed.
Zhang Suli reflected that one step wrong must be 100% correct. Even if the work order of a small step is not well arranged, it will affect the overall situation.
In order to achieve the unity of heart and hand, Zhang Suli trained harder. Slowly, one file goes down, and she knows that she can work harder, file more, and do one file accurately.
Zhang Suli has participated in many competitions, and the second China South Locomotive Vocational Skills Competition is the most important competition for her to enter the factory. In the locksmith competition, all the players are male, and she is the only female player.
At the beginning of the 8-hour competition, Zhang Suli didn't grab the instant speed. It took her half an hour to make the arrangement, and then she took her time.
Zhang Jianmin, the leader of CSR Luoyang Locomotive Works, said: "During the whole competition, Zhang Suli's expression hardly changed, and she was completely immersed in her work, as if she were just doing an ordinary day's work."
Zhang Suli won the first place with absolute strength. She was awarded the title of "South Locomotive Technical Model" and later won the title of "National Technical Expert".
Honor followed. In 2004, Zhang Suli won the Chinese Skills Award, the title of National March 8th Red Flag Bearer and the National May 1st Labor Medal.
After 10 years of hard work, it finally produced the most beautiful fruit.
Teach the skills of solving problems.
In the roaring workshop of Luoyang Locomotive Works, there is a clean small office with many advanced equipment, and the iron cabinet against the wall is filled with all kinds of locksmith tools.
Close the iron gate and let the noise calm down. There are many excellent technical experts here; Here, a technical problem is overcome.
This is Zhang Suli's national skill master studio. Here, Zhang Suli brought out many excellent apprentices.
There is a girl named Guo Yuru who has never won a place in any fitter competition.
In the workshop, Zhang Suli found that the girl's locksmith was solid in basic skills and hard-working, so she took the initiative to accept her as an apprentice. "I know very well that the small fruit is aura. After carving, it will definitely become a tool." Zhang Suli said.
Zhang Suli understands that taking an apprentice is not a simple matter. The key is to teach students in accordance with their aptitude and pay attention to everyone's habits and characteristics.
On one occasion, when Guo Yuru made a workpiece, the surface roughness required by the drawings was 1.6 micron, but how she grinded it was between 1.7- 1.8 micron. Zhang Suli found that her posture was very standard, but the lines on the workpiece after filing were wrong, mainly because of the force. Filing the workpiece is too light to file iron filings; If it's too heavy, it's too difficult to file. It needs just the right strength.
Zhang Suli helped Guo Yuru adjust her strength according to her habit of using tools. Soon, Guo Yuru made an accurate workpiece.
Guo Yuru made rapid progress under the guidance of Zhang Suli, and participated in the third vocational skills competition for employees in Luoyang on behalf of the company. As the only female player who reached the final of the locksmith group, Guo Yuru was calm and fearless, and won the locksmith group crown with her exquisite skills. Guo Yuru also participated in the 3rd Workers' Technical Games in Henan Province on behalf of Luoyang City, won the third place in the final of the fitter group and was awarded the honorary title of "Technical Model of Henan Province".
In just two years, there are 3 1 apprentices in Zhang Suli's studio, of which 7 have obtained the certificate of senior technician, 1 1 have obtained the certificate of technician and 2 1 have obtained the certificate of senior engineer.
In 20 14, the Hong Kong Metro Company commissioned Luoyang Locomotive Company to make a flaw detection vehicle, and the final detection completely depended on the damaged rail. A broken rail used for inspection costs at least 80,000 yuan in the market, and Zhang Suli led the studio to win it at a cost of less than 654.38+100,000 yuan.
It is difficult for assemblers to make damaged rails. The track is fixed on the ground, so the direction of the fitter's force is very limited, and the space of the tool saw is not enough; The track is not smooth enough, so it is difficult to achieve accuracy ... Zhang Suli remade the tools according to the design requirements and successfully completed the track production.
Zhang Suli is an intellectual of locksmith. When workers in the factory encounter problems that cannot be solved, she is the first thing that comes to mind.
Once, the company tried to repair the first Harmony locomotive. Several special-shaped bolts were not removed all day and night, which made the distribution cabinet unable to be repaired. Long Wu, the company's deputy chief engineer, called Zhang Suli and asked her to come over. After she arrived at the scene, she took a look, thought for a while, drew for a few minutes, and it took 10 minutes to work out the demolition plan. In less than 30 minutes, all the special-shaped bolts were removed and the power distribution cabinet went smoothly. Zhang Suli won a round of applause.
Zhang Suli is in her prime, and she will continue to improve her skills and win more wonderful things ... A new generation of heavy rail vehicles has been successfully developed and put into use in CSR Luoyang Locomotive Company. (China labor and social security newspaper Yu Yilin)
