Second, the work performance
1. Personal moral integrity
A tree is a painting, and a forest is a landscape. Li Bin always believes that no matter how great one’s personal skills are, it is only a single strength. Only by cultivating and bringing out more "smart workers" can we effectively promote enterprise development and social development.
Through Li Bin Studio as the carrier, Li Bin trained and trained a group of technical backbones who love the enterprise, love their jobs, have dedication, can study hard and work hard. Through the training of key projects, many studio members have made outstanding achievements in their jobs.
2. Excellent professional ability
Since 2012, Li Bin has led the members of the studio and made many breakthroughs in the localization project of A6V variable motor:
2.1 A6V series of new product development projects
The project has completed seven series, including A6V28, A6V55, A6V80, A6V107, A6V160, A6V200 and A6V250, including new product development and small batch production, and the performance of the products has basically reached the level of similar products of Rexroth.
2.2 A6V series cylinder measurement key project
According to the characteristics of NC machine tool processing and the measuring principle of three-coordinate measuring instrument, a set of simple and practical coaxiality measuring die is designed.
This measurement method is simple and reliable. Now this spherical measuring mold has been manufactured and put into use. The coaxiality between the axis of the seven holes in the cylinder body and the spherical surface can be controlled within 0.02 mm. The quality of the cylinder body is greatly improved.
2.3 Manufacturing Project of Assembly Line of Inclined Shaft Piston Pump
Through the analysis of the upper and lower stations and fixture positioning, the project organized the improvement of the assembly line. After the trial assembly of the products, the assembly line was gradually improved, which achieved obvious improvement effects: through the active participation and cooperation of various departments, the design and manufacture of the assembly line of the inclined shaft piston pump were completed, and the quality and efficiency of production were greatly improved.
2.4 Design and application of casting mould for motor cover and shell of variable speed motor
The purpose of the project is to solve the problems of looseness and sand holes in the casting of the motor cover and shell of variable speed motor.
According to the characteristics of the product, the casting mold was redesigned and made. The metal mold was used for assembly line casting, and the whole casting process and various parameters were controlled by computer. It plays a very important role in improving product quality and reducing scrap rate.
Through a series of project innovations, such as A6V series new product development project, A6V series cylinder measurement tackling key problems project, inclined shaft piston pump assembly line manufacturing project and variable motor motor cover and shell casting mold design and application project, A6V series inclined shaft hydraulic variable motor has reached the international advanced and domestic leading level.
3. Outstanding work performance
High-pressure axial piston pump/motor is an important component of hydraulic system. The low level of basic technology in China leads to the domestic hydraulic technical performance and reliability far behind that in Germany, which has become a bottleneck restricting the development of main engine. The development of domestic high-end construction machinery mainframe industry depends entirely on imported hydraulic components, and the national military products are also greatly affected.
In order to revitalize the hydraulic technology in China, Li Bin took the initiative to propose and undertake the innovative research project of "Key Technologies for Localization of High-pressure Axial Piston Pump/Motor", with the goal of increasing the maximum pressure from 25MPa to 40MPa and the maximum rotation speed from 1,500 r/min to 6,000 r/min, so as to meet the performance requirements of high-end hosts. He led the project team, and through the design and application of 11 technological innovations, laid the foundation for the key technical indicators of the products to reach the international advanced level. Through the third-party type test, the main technical indicators have completely reached the German peak pressure and the highest speed. The appraisal conclusion of Shanghai Economic and Information Commission on "Key Technologies of Localization of High-pressure Axial Piston Pump/Motor" is: "The project has reached the domestic leading and international advanced level in general." The project won the second prize of National Science and Technology Progress Award and the first prize of China Machinery Industry Science and Technology Award.
In recent years, Li Bin led the team to make a breakthrough in the project of high-pressure axial piston pump/motor, and further developed the more advanced A6V series variable motor domestically. A6V series oblique-shaft hydraulic variable-speed motors are widely used in the construction machinery industry at present, for example, they can be used to hoist and rotate crawler cranes, and they are important basic parts of construction machinery. However, A6V series inclined-axis hydraulic variable-speed motors used in China’s construction machinery industry have long relied on imports and are basically monopolized by international giants in Europe and America.
Due to some domestic fields, such as metal materials, heat treatment technology of metal materials, high precision and high precision machining technology, there is still a certain gap compared with the international advanced level. The A6V products produced by us have many problems, such as many early failures, unstable processing quality and low qualified rate of parts processing. In order to change these technical problems of A6V products, Li Bin Studio took A6V product technical research as "Model Worker Innovation Studio Project". After the completion of the project, the annual sales revenue of variable displacement pump/motor series products related to this key project exceeded 6 million yuan.
The breakthrough of key technologies has enabled China to truly possess the internationally advanced manufacturing technology of variable speed motors. By tackling the key problems of localization, we truly have the international advanced manufacturing technology of hydraulic components, which has practical and long-term significance for changing the backward situation of basic hydraulic components in China.
Third, the economic and social benefits achieved
1. Economic benefits
In 2015 and 2016, due to the influence of macro-control, the construction machinery industry was not prosperous, and the sales of major domestic main engine plants all dropped significantly, but our variable displacement pump/motor products still achieved sales of 7.57 million yuan and 6.14 million yuan respectively. Since the end of 2016, with the gradual deepening of the national "One Belt, One Road" strategy, the construction machinery industry has gradually stepped out of the trough. Especially since January 2017, the supply of hydraulic pumps/motors produced by our company has been in short supply in the construction machinery market in China, and the sales volume has greatly increased compared with previous years. In 2017, the sales volume of products related to key projects was 9.213 million yuan, which achieved good economic benefits for enterprises.
2. Social benefits
2.1 Breakthrough of key technologies
The breakthrough of key technologies has enabled China to truly possess internationally advanced A6V series product manufacturing technology. Rexroth’s hydraulic technology has been in the leading position in the world for a long time. By tackling key problems in localization, we have truly advanced international hydraulic component manufacturing technology, which has practical and long-term significance for changing the backward situation of basic hydraulic components in China. Breaking Rexroth’s technical monopoly, realizing the full localization of high-end hydraulic components, greatly reducing the supporting cost of the main engine, saving the national foreign exchange and promoting the national "Belt and Road" strategy have great social benefits.
2.2 Product performance and reliability have been greatly improved.
With the improvement of product performance and reliability, the company’s products have been designated as supporting products for military industry, which are used for supporting 09Ⅲ and 09Ⅳ steering gear, a new generation of self-propelled gun launchers and missile destroyers. The supporting products participated in the military parade of the 90th anniversary of the founding of the People’s Liberation Army in China at the end of July 2017, visited Hong Kong for the escort ship of the Liaoning carrier in July 2017, and went to the Gulf of Aden for escort operations and China naval parade in September 3, 2015.
