Craftsman spirit is a rigorous and serious, excellence, the pursuit of perfection of the spirit, with the spirit of craftsmanship, often can be decades as a day, and constantly pursue the ultimate in skills. In the production line of Lanshi Group, there is such a lathe technician who carries the spirit of craftsmanship and constantly breaks through himself - Zou Bin.
In Lanshi Group, when Zou Bin is mentioned, no one knows and no one knows. From a lathe operator to the director of the workshop, and then to the person in charge of lanshi group "Zou Bin labor model studio", in the 30 years of career, Zou Bin has won many honors such as "Gansu Province Youth Post Expert", "National Youth Post Expert", "National Labor Model", "National May Day Labor Medal" and so on, and his professional lathe skills are among the best in the country and have won high praise from industry experts.
Zou Bin taught his apprentices skills
The little lotus only shows its sharp corners
In 1991, Zou Bin was assigned to Lanshi Group by the technical school, and had the honor of learning from Comrade Jin Heying, a provincial labor model and a national March 8th Red Flag bearer. During the internship process, Zou Bin was touched by the master's hard-working, always demanding her spirit of being a Communist Party member, and her love for the collective and concern for comrades, and was even more impressed by her exquisite skills. "Follow the master to do a good job, study the technology hard, develop a good work style, become an excellent technician as soon as possible, and be a technical person like the master" has become the belief he has adhered to all his life. Inspired by his faith, he studied seriously, studied diligently, and whenever he encountered a problem, he always tirelessly asked the master for advice, learned from the elders, wrote down the problems, made notes, and then looked up the information after returning home until he completely understood, and gradually, Zou Bin found fun in his work, grew up rapidly, and became the best among the young people in the factory. Over the years, there have been dozens of books that record various problems and experiences in work. In 1983, Zou Bin, who had only been working for more than two years, made his debut in the provincial skills competition and won the eighth place in the province. In the more than 10 years since then, Zou Bin has grown into a top technical expert in the factory and has taken the lead in completing many difficult tasks. In particular, since the establishment of the national skill master studio and the labor model innovation studio named after Zou Bin, its team has completed more than 30 technical research and operation innovations, obtained 9 national patents, and published 4 technical papers in national and provincial journals, of which 3 were awarded the "Provincial Advanced Operation Method for Employees".
Zou Bin processed products
The elderly machine tool is revitalized
P-2200 mud pump is china's most advanced high-power, high-pressure mud pump, is the group to meet the land and sea more than 9000 meters deep well drilling process needs in 2011 into the research and development of new products. Among them, 107.37.20.01 gear shaft is the key transmission component of P-2200 type mud pump, this type of mud pump adopts gapless herringbone transmission, and the planing tooth processing of the gear shaft has become a difficult point. In the process of product development, the only processing equipment was a Synces cutting machine shipped in 1928, which was more difficult than imagined to process modern high-precision products with an antique-grade equipment. To this end, Zou Bin spent a lot of energy in the early stage to repair the Sykes gear planer to ensure continuous stability in the work. During processing, due to the lack of matching brackets, the difficulty of positioning the workpiece and other factors will affect the accuracy of the tooth surface of the processing. Comrade Zou Bin conducted in-depth research and adjustment of the equipment and transmission system in view of the technical requirements of the product, and after calculation, he innovatively designed the clamping and dial positioning device, and successfully solved the technical problems. In practical application, it is convenient and fast, the positioning accuracy is high, the correction speed is 10 times higher than the original tooling, and the accuracy and size of the processed gear shaft fully meet the requirements of the drawing. At present, only Lanshi Group can process the gear shaft in China, and the export earns more than 10 million US dollars.
Zou Bin teaches skills to employees at the production site
Diligent thinking and good at learning to solve problems
Pressure vessel 10186Q-66 opening to take over the solid material, the length of 2.874 meters, the overall requirements of the inner hole to be processed to the size of ¢213mm, the amount of cutting during processing, whether in the lathe or boring machine processing, hole depth tool rod rigidity is the main reason for limiting the depth of the knife, processing efficiency is very slow. After careful study, Zou Bin believes that the rigidity of the knife shaft is the main reason for affecting the depth of the knife and the processing accuracy. If the rigidity of the boring rod can be solved, the processing difficulties will be solved. Subsequently, Zou Bin launched a technical transformation, which successfully avoided the vibration caused by the weak rigidity of the tool holder, improved the depth of the knife for a single turn, and improved the overall efficiency of the processing. This improvement not only greatly reduces the production cost, but also increases the processing efficiency by more than 3 times, effectively ensuring the production schedule. The use of accessories to make support blocks, compared with the original boring machine processing costs reduced by more than 3 million yuan.
It can break the bottleneck
In 2018, Zou Bin invented two utility model patents of "Crank Slider Mechanism Multi-cylinder Mud Pump" and "Arc Jack". "Crank slider mechanism multi-cylinder mud pump" is an innovative structure of the double-acting mud pump structure form, is the first time lanshi group to the front-line workers and R & D personnel to complete the utility model patent, the technology broke the traditional mud pump structure, applied to the development of 3200 horsepower high-power mud pump products, the project accumulated effect of about 9.56 million yuan; "arc jack" patented technology to solve the 2200 horsepower mud pump manufacturing in the drive shaft gear processing positioning problem, simple structure, accurate positioning, The processing process is stable, and the patent has been transformed into a mature process flow, with a cumulative cost saving of 8.5 million yuan. In addition, Zou Bin also completed the process research and development of key processes of ZJ80D drilling rig roller shaft and other products; assisted Lanshi Detection Technology Co., Ltd. to complete the design work of the "Development of Bolt Guarantee Load Test and Measurement Device for Nuclear Power", which won the first prize of lanshi group QC quality management activity competition; carried out tool cost reduction work, promoted the localization of tools, and saved more than 8.32 million yuan in tool costs every year.
Teach new buds by example
In order to pass on the craftsman spirit and exquisite skills to more people, Zou Bin also specially compiled a number of courseware, summarized and popularized advanced operation methods, and successively opened multi-period CNC knowledge and CAD software training for front-line workers. Established a national-level skill master studio, and signed a "master-apprentice agreement" with a number of backbone young workers. There are 13 people who have obtained the qualification of senior technicians, 10 people who have won the title of "Gansu Provincial Technical Expert", 5 people who have won the title of "Gansu Provincial Technical Pacesetter", and 2 people who have won the "Gansu Province May Day Labor Medal". Now Zou Bin Studio has become a practical platform for the vast number of front-line employees of Lanshi Group to delve into learning, technological innovation and pass on skills. The studio was named "Gansu Provincial Exemplary Labor Model Innovation Studio" by the Gansu Provincial Federation of Trade Unions in 2015, and "National Skill Master Studio" by the Ministry of Human Resources and Social Security in 2017.
The value of labor models is not only selfless dedication, thirty years as a day, delve into lathe skills, hard work, but also a pair of eyes and a pair of skillful hands cultivated in the long-term struggle, manufacturing for the country, creating for the country is a lifetime of ingenuity.
