with the technical innovation and demand upgrading, new jobs have been born in the field of engineering technology. The picture shows that Feng cunjiang (left), an engineer of fuel cell hydrogen cylinder, is instructing his colleagues to carry out winding operation of type III hydrogen cylinders. There are only three similar production lines of

and

in the world.

and

put a round aluminum plate into a special stamping equipment, so that the sheet metal is directly subjected to deformation force in the die and deforms. Thus, the inner tank of a hydrogen cylinder of a fuel cell vehicle is preliminarily formed and transferred to the next unit for processing This is the scene of the aluminum sheet deep drawing production line of Sinoma Technology (Chengdu) Co., Ltd. When the reporter met “fuel cell hydrogen cylinder engineer” Feng cunjiang, he was standing beside the production line to conduct technical exchanges with the workers. There are nearly 30 processes of

and

, each of which is quite familiar. The “weight” of

and

cylinders is 350 kg / m2. I’m sorry to have kept you waiting Feng cunjiang walked at a brisk pace as he turned back to say hello to the reporter. His phone rang again. As a deputy chief engineer, he is very busy, often in various workshops, wechat steps often more than 10000. “There are nearly 30 processes from an aluminum plate to the final hydrogen cylinder, and I have to know every one,” he said Feng cunjiang’s daily work, in addition to routine inspection, check the quality of the project, he also has to solve the problems in the process of product delivery, bring the feedback from the market back to the workshop, and timely rectify and implement. In the face of numerous orders and tight schedule, Feng cunjiang will return to the production line to fight with his fellow workers.

if you can’t find Feng cunjiang in the office of the factory during the day, most of them can see him on the production line. Wearing uniform overalls and crawling in the pile of parts, it’s really difficult to connect him with the identity of deputy chief engineer. “The carbon fiber is evenly wound on the cylinder liner layer by layer like a tangle, making the pressure bearing strength of the whole cylinder reach 35 MPa.” Feng cunjiang pointed to one side to introduce to reporters, that is to say, every square centimeter to bear 350 kg of pressure. With such a large pressure, hydrogen is compressed into the cylinder. As long as three such hydrogen cylinders are carried, it is enough for a bus to travel continuously for 400 kilometers. As a kind of green energy,

and

are usually in the form of gaseous hydrogen, which is flammable, explosive and easy to diffuse, which puts forward high requirements for the safety of hydrogen cylinders for vehicle fuel cells. The cylinder wall with a length of about 1 meter is processed with aluminum tube according to the traditional process, and the product formability is not good enough. In order to do such a “porcelain work”, Feng cunjiang and his colleagues designed the mould, studied the processing technology repeatedly and tried and wrong on the basis of the company’s original CNG steel liner drawing production line. “Our hydrogen cylinder liners are formed by aluminum sheet drawing. Compared with aluminum tube forming, the process of bottom sealing can be omitted for the inner liner formed by sheet metal. The internal and external surface of the product is smoother, and the tightness between the inner fiber is higher, which can greatly improve the fatigue performance of the product

and

have led in the development of carbon fiber fully wound cylinder with steel liner. The “light” of

and

cylinders has reduced the truck weight by about 1 ton.

and

have identified the professional direction of technology since the beginning of my work. From designing drawings to making objects that meet the standards is a great achievement. ” In Feng cunjiang’s view, in the kingdom of pressure vessel manufacturing, as long as they are willing to study, there is no problem that cannot be solved. With such a belief, Feng cunjiang constantly summed up, explored the rules, and successively solved a number of technical problems, creating considerable economic benefits for the enterprise, and was awarded the title of “Chengdu craftsman” last year. As a party member,

as a party member, he interprets “craftsman spirit” with practical actions. “From natural gas cylinders to hydrogen cylinders, the technology is constantly iterating, and the industrial boundary is becoming more and more blurred.” Feng cunjiang told reporters that in order to improve the technology, we need to continue to learn after work. Feng cunjiang bought many books and worked overtime to study. What should I do if I can’t understand the knowledge in the book? He studied the problems and the knowledge in the book. “If you don’t have a foundation, learn from scratch.”

In the past three years,

has achieved rapid growth together with the enterprise in the past three years: the CNG deep drawing cylinder led by the company has reached the international advanced level. With the help of this production line, it has independently developed the CNG tank drawing technology, which has obtained the invention patent; it has led the development of carbon fiber fully wound cylinder with steel liner, and the weight of heavy truck vehicle using the cylinder has been reduced by about 1 ton We warmly welcome the heavy truck enterprises and users, and the product supply exceeds the demand. We have participated in the development of the large diameter composite gas cylinder for luck. The application of the product can increase the amount of luck of the automobile by more than 30% After

and

participated in the work, Feng cunjiang followed the company to work in Suzhou, Nantong and Chengdu. If you compare the company to a sailing ship, he has proved that he is a very competent “good sailor”. What a big ship needs is a group of “good sailors”. Now Feng cunjiang has taken on the responsibility of cultivating more skilled talents: “the factory is not as warm in winter as in the office, but it can make people progress faster and master the practical operation more clearly.” He said that what he valued most was to realize his self-worth in the factory.

reporter notes that the

new occupation reflects the new driving force of industrial development. Zou Zedong, a blockchain engineering and technical personnel of

in the science and technology branch of Bank of Chengdu, often visits enterprises in the early morning, explains loan products and communicates with enterprises. Customer marketing, pre credit investigation, loan review, contract lending, post loan inspection… To complete an enterprise loan, small and micro credit officers often need to communicate repeatedly. Wang Hanfeng, general manager of China India supply chain base construction center of

Through continuous interaction with consumers, the company improves the production process and material of shoes. E-commerce live broadcast also enabled enterprises to achieve sales of more than 10 million yuan in the first half of this year.

and

from natural gas cylinders to hydrogen gas cylinders, the technology is constantly iterative, and the industrial boundary is becoming more and more blurred. In order to improve the technology, Feng cunjiang, deputy chief engineer of Sinoma Technology (Chengdu) Co., Ltd., is constantly learning after work.

blockchain engineering and technical personnel, small and micro credit officers, supply chain managers, Internet marketers, baby sitters, car beauticians, bartenders Since the promulgation of the people’s Republic of China Classification of occupations (2015 Edition), China has published three batches of 38 new occupations. In addition, there are a large number of emerging or have begun to take shape of the new occupation has not been included. Looking at the industry through the new occupation, a new occupation tide tide times, will certainly beat the powerful industry pulse.

and

are emerging in Chengdu with technological innovation and demand upgrading. New occupations required by major vertical formats in engineering and technical work and modern service industry are also gradually born. In particular, in the overall promotion of normalized epidemic prevention and control and economic and social development, the digital economy represented by online education, live delivery and supply chain management has developed vigorously, generating a large number of new jobs, and the recruitment demand of enterprises in the industry is also rising. These new jobs rely on new business forms, new models and industrial upgrading, which also show the driving force of Chengdu’s economic and social development.
