First, the bearing manufacturing operation in the green production era since the 1990s; China's bearing industry on the basis of improving quality, optimizing planning, and improving efficiency; gradually adjusting the strategy; making the production planning and regional planning unreasonable situation improved; The level of skill continues to improve; it now constitutes a system of better production and skill systems; it has become the fourth largest country in the world after Japan, the United States and Germany. However, bearing engineering has little research on green production skills; There are few types of bearings with difficulty and high added value; the quality of the products is low; although the company has many; but the production capacity is low, in the theory of bearing depiction and production; there is still a considerable distance compared with the developed countries in the West. Moreover; resources and original data consumption Larger; production noise is also high; the discharge of cutting fluid, coolant, exhaust gas, waste liquid is also more serious to the environment; thus affecting the sustainable development of China's bearing industry. In view of this; bearing green production can be bearing industry Sustainable supply guarantees.
Second, the fundamental characteristics of China's bearing industry green production 1. The main content of the bearing industry green production 1) the manufacturing scope of the bearing industry. It includes the whole process of the product life cycle, 2) the environmental category of the bearing industry, 3) the resource category of the bearing industry. The green production of the bearing industry is the three major categories. Interspersed and integrated.
2. Bearing industry green production should first consider the "five green" problem; that is, bearing green depiction, narrow bearing green production, bearing green packaging, bearing green transportation, bearing green application, bearing green protection.
3. Bearing industry green production of the primary benefits; implementation of the bearing industry green production; maximum limit to improve resource utilization; can directly reduce bearing costs, reduce or eliminate environmental pollution; all improve or optimize the working environment of the bearing company employees; improve operational safety Cut unnecessary expenses; help to improve the subjective initiative and efficiency of employees.
Secondly, the green production of the bearing industry will enable the bearing company to have a better social image; add intangible assets to the company. Therefore, China's bearing industry treats green production; it should not passively abide by the rules made by the government or social morality; Green production should be regarded as a strategic operation resolution plan; that is, the implementation of green production is a kind of opportunity for the bearing company. According to the actual situation; the efficiency of bearing green production is compared with the cost; then the economic benefits of bearing green production are determined. .
In summary, the benefits of green manufacturing in the bearing industry are the integration of social and economic benefits.
4. The information integration green production system in the bearing industry green production system not only touches all the information and integration of the usual production system; but also focuses on the integrated disposal of resource consumption information and environmental impact information; and will process the information flow, material flow and The energy flow is organically connected; systematically integrated and optimized.
5. The integrated bearing green manufacturing process of the bearing industry green production covers every process of the bearing product life cycle; it is the integration of multiple life cycles based on the database and its data exchange specifications.
6. The bearing industry green production set success strategy system bearing green production function policy model referred to as TQCSE model; during which T indicates time; Q indicates quality; C indicates cost; S indicates service; E indicates environment, which means green production skills; Can eliminate the negative impact of the environment to the greatest extent; improve environmental benefits.
7. Bearing industry green production of social integration characteristics bearing company to implement green production; it is necessary to consider the recovery and disposal of the bearing product life after the end; this can constitute a new integrated contact between the bearing company, bearing products, bearing users .
Third, the bearing industry green production strategy system and key skills 1. The bearing industry green production strategy system includes six green functions: bearing green management information system, bearing green depiction system, bearing green production process system, bearing green quality assurance system, bearing green material resource system, bearing green environmental impact assessment system. Sub-system; computer communication network system and database/knowledge database system and other two supporting systems and external contact. For the sake of distinction; generalized bearing green production; referred to as green production, narrow bearing green production; referred to as green production In the whole process of the life of bearing products; obvious; green depiction of bearing products, green production, green recovery is essential; thus it has become the primary skill of the bearing industry.
Bearing green depiction is about thinking about the function, quality, development cycle and cost of the product; optimizing the relevant delineation elements; minimizing the overall impact of the product and its production process on the environment. The green depiction is also known as the environmentally oriented depiction ( Design for Environment, DFE).
Bearing green production is the performance of sustainable development in the field of production. The primary performance is health production; its ambition process is a net formation from parts to products based on nano-scale production skills. In the process of production and production of products; It is necessary to select environmentally-friendly and energy-saving data processing, parts production and installation technology; it is also necessary to consider the impact of the working environment of the production part on everyone's physiology and mind. This is in line with laws and regulations (the implementation of the "Occupational Disease Prevention and Control of the People's Republic of China" on May 1, 2002 The requirements of the law; and the moral character of human beings.
The bearing green pick-up demand bearing production company; close contact with the waste disposal part and the data processing company to cooperate; explore the material flow and energy flow that fits the sustainable green view; make the ecological capital, economic capital and social capital increase together.
2. The key skills of the bearing industry green production are because the bearings belong to the fine mechanical parts; they are also made of hard wear-resistant materials; their production usually needs to be completed by turning, grinding and other processes; this must use cutting fluid, grinding Cutting materials and other substances that are polluting the environment. Following the development of cutting tools and cutting skills; there have been many studies on the use of dry and hard cutting for bearings at home and abroad. But because the bearings are parts that are full of alternating stress; how effective Controlling the residual stress state of the processed surface; it becomes the key to the promotion and application of this skill.
At that time, foreign countries had previously undergone hard turning and then bearing the bearing raceway bearing rolling process; it is said that this method not only reduced the cost to the original 55%; the life is also improved by five times. Domestic hard on the bearing The turning skills are still in the test period; how to improve the bearing processing technology; after changing the cutting conditions and methods; the automatic control of the stress condition of the bearing processing appearance is the key skill of the Chinese bearing professional to complete the green production.
