Sixth, the future of the effect of vibration: 1. Replacement of heat aging is the development trend: Since human beings entered the industrial society, there have been three profound and profound changes. These three industrial revolutions were the invention of the 18th century steam engine, the invention of the generator in the early 19th century, and the 20th century. The invention of the mid-plane computer is an important symbol. These three changes have promoted the rapid development of social productivity, affecting and changing people's lifestyles. However, it has also seriously damaged the environment in which human beings live, and the earth that we live in has become riddled with more and more serious problems. People have to face increasingly serious environmental problems while changing their lives. Resources are non-renewable and the destructive environment is difficult to reverse. Saving energy and reducing emissions have become the focus of governments. Energy conservation and emission reduction have also been the focus of work at all levels of government in China. The 11th Five-Year Plan has set clear targets for energy conservation and emission reduction. The Party Central Committee and the State Council have put forward clear guidelines and policies for the development of circular economy, resource conservation and environmental protection. In the report of the 17th National Congress of the Communist Party of China, General Secretary Hu Jintao clearly pointed out the development and promotion of advanced and applicable technologies for saving, replacing, recycling and pollution control, developing clean energy and renewable energy, protecting land and water resources, and building scientific and rational energy resources. Use the system to improve the efficiency of energy resource utilization. Develop environmental protection industry. Increase investment in energy conservation and environmental protection, focus on strengthening pollution prevention and control of water, air and soil, and improve urban and rural living environment. Premier Wen Jiabao also made a special action to organize the implementation of energy-saving and emission reduction technology in the national video conference on energy conservation and emission reduction, and set up a number of national engineering laboratories and national key laboratories to overcome a number of key technologies and common technologies for energy conservation and emission reduction. Actively promote the construction of energy-saving and emission reduction technology innovation and achievement transformation system with enterprises as the main body, combining production, education and research, and enhance the independent innovation capability of enterprises. In key industries such as power, steel and non-ferrous smelting, we will promote a number of major energy-saving and emission-reduction technologies with great potential and wide application. Formulate policies and measures to encourage and support enterprises to carry out technological transformation of energy conservation and emission reduction, and adopt important instructions for energy-saving and environmental protection new equipment, new processes and new technologies. In the machinery manufacturing industry, some processes with obvious high energy consumption and high pollution are subject to great restrictions. Vibration aging has an incomparable energy-saving and emission-reducing advantage compared with thermal aging, and it is partially better than thermal aging in other aspects. Thermal aging vibration aging comparison Aging method category Hot aging furnace (15 tons) Vibration aging (a set of spectrum harmonic devices) Manufacturing purchase cost Need to build an aging furnace with a long time period The device is light. No need to build for a long time Aging cycle 12 hours 1 hour Energy consumption High (mainly burning coal, burning gas, electricity) Open once (about 12 hours), the cost is 3000-5000 yuan, Low (about one hour and one hour, roughly calculating its energy consumption is only 0.2% of the heat aging, the cost is only 8-10% of the heat aging.) Floor area It has a large area and needs a fixed site and cannot be moved. It has a small footprint, no need for a fixed site, easy to use, can be moved at will, and the power requirements are not high (normal AC 220V power supply can be). Ageing workpiece volume For large or long workpieces, it is impossible to enter the furnace for aging treatment (the aging furnace that can generally accommodate workpieces over five meters long is rare, and if it is too long, it will not be able to enter the furnace at all) There is no special requirement for the size of the workpiece, and it can be aged by replacing the exciter model. Processing effect 1. The temperature in the furnace door, furnace and furnace is poor, and the workpiece processing effect at different positions is unstable. 1. The overall vibration of the workpiece, the multi-vibration type solves the problem of eliminating the residual stress concentration parts of the workpiece. Change the material properties of the workpiece 1. For structurally complex workpieces, problems will arise in changing the material properties of the material. 2, aluminum alloy and other new materials, because the temperature of changing tissue properties is low, can not use thermal aging It does not change the material structure characteristics, and can perform stress relief treatment on aluminum alloy and titanium alloy. Environmental pollution very serious No (the residual stress is removed by applying mechanical energy, so there is no environmental pollution) Other benefits To improve production efficiency, the economic and social benefits of energy conservation and emission reduction cannot be estimated. The application of new spectrum harmonic technology in the field of vibration aging has made it possible to replace thermal aging by vibration aging, and it is an inevitable development direction. The backward process technology with high energy consumption and high pollution is eliminated by the new green technology. The inevitable trend is the inevitable need of human survival and development. I believe that in 2009 or 2008, there will be a year of vibration aging. 2. The ability to provide sustained growth for companies is the future of development: Production companies need to adjust their own products according to the changing market demand, in order to participate in market competition more effectively. At present, the application of new technologies and new materials is changing with each passing day, which brings more development opportunities for enterprises. Enterprises can also face new problems: the application of new technologies, new materials, existing production equipment, and process equipment can meet the requirements of new production? According to the original equipment provider's service, the answer is no. The equipment provider can only provide the warranty service for the limited equipment purchased. It can only partially solve the current problems of the enterprise, and the new demand for the enterprise needs to be solved by continuously purchasing new equipment and designing a new process plan. It can be said that every time the adjustment of production, enterprises are faced with the indispensable process of technological research and equipment transformation. What follows is the high cost, the pain of transformation, the idleness of the original equipment, the waste of funds, and the risk of failure that may exist. So, what companies need to get is a growing ability to solve problems, which is more meaningful than getting a set of state-of-the-art equipment. Equipment providers also need to consider how to serve the enterprise and transform it to help the company improve its capabilities. As early as 1968, the American economist Fuchs pointed out in his book "Service Economy", which later became a classic book: "We are now in the 'service economy'... More than half of the employed population is no longer Engaged in the production of food, clothing, housing, automobiles and other tangible products." Fuchs's "revolutionary declaration" was developed in the 1970s and the theory of "post-industrial society" emerged. In 1973, American sociologist Daniel Bell published the book "The Coming of Post-industrial Society", which analyzed the important characteristics of post-industrial society and pointed out: "If industry defines social quality by commodity, post-industrial society is to serve To define social quality." The services referred to here include both service activities within the traditional service industry, as well as pre-sale, in-sale and after-sales service activities in the manufacturing industry. According to statistics, in general, the service industry in developed countries accounts for at least 65 percentage points of their overall economic activities - twice the current proportion of China. It can be seen that in the next period, the gap in the service industry in China will be a huge opportunity. At the same time, product-centric manufacturing, which has been in development for hundreds of years, is also expanding in the service direction. The services provided range from manufacturing products in pure form to manufacturing products that include purely physical forms of manufacturing, but also include an increasing number of non-material forms of service development. This is a tremendous progress in history and a huge development and progress in the manufacturing industry. From the perspective of the development of the world's manufacturing industry, the increase in the proportion of services is the main sign of the higher-level manufacturing industry, and the application of high-tech has opened up a vast world for the expansion of service content and the improvement of the level of manufacturing services. From a global perspective, modern industry in developed countries has developed into a manufacturing/service phase, and services are manufactured. The important development direction of the industry in the future, about 40%-50% of the world-class manufacturers' output value is composed of services. In summary, providing services to enterprises is not only the needs of enterprises, but also the needs of equipment providers to develop. Many international large enterprises have already carried out or completed this transformation. Back to our theme, aging treatment process is an important part of mechanical manufacturing. In the future development, vibration aging replaces thermal aging is the inevitable road, and excellent equipment suppliers, relying on the background of new technology, It is the fundamental development path for enterprises to provide high-quality services and provide enterprises with the ability to continuously solve residual stress problems. It is the ultimate development goal to completely change the current backward processing methods.
