The Remanufacturing Research on the Key Parts of Engineering Machinery

Abstract

With the rapid development of construction machinery industry, especially as domestic rapid economic and social development of the strong demand for engineering machinery, engineering machinery manufacturing industry is facing pressure from various resources saving and environment friendly requirements, development of remanufacturing technology, to carry out the green remanufacturing technology for engineering machinery research and development and application is more urgent. Because of the construction machinery's huge and continue to increase, reason for remanufacturing, make full use of the materials of the surplus value has important economic significance and social significance. Introduction Engineering machinery as an important part of the machinery industry, has become an increasingly important role in the economic construction, with the steady growth of economy, engineering machinery industry also showed vigorous vitality. Engineering machinery usually exists the weight more than large, production material consumption, retired after the big issues such as environmental pollution [1]. On the one hand, engineering machinery is generally fast update, there are a lot of equipment due to not adapt to the needs of the development of social economy, in has yet to reach its design life of the retired in advance; Engineering machinery parts, on the other hand, the number is more, the service life of the parts, after the machine scrap, there are quite a number of parts can be directly recycled or reprocessing, it can greatly improve the utilization rate of resources, reduce waste mechanical the damage to the environment, at the same time also can improve the economic benefit of enterprise. Remanufacturing engineering as an important part of green design, is in order to save resources, save energy and protect environment as characteristic, since entering the China, combining with the current our country the requirements of sustainable development, is accepted by more and more enterprises, and into the actual production process [2]. Remanufacturing engineering involved in automobile, machine tools, engineering machinery and other fields, including in the field of engineering machinery, the traditional product design mainly depends on the designers have the relevant design objects involved in the field of professional knowledge, and mostly focus on product after put into use to keep it, becomes available status or be reused or a series of technical measures taken by engineering activities, and put into use before the design work of product is less concerned and studied. The basic theory of remanufacturing America first proposed the concept of remanufacturing and waste-free process. Remanufacturing refers to equipment the whole life cycle theory as the instruction, in order to realize the waste equipment performance improvement as the goal, to high quality, high efficiency, energy saving, material saving, environmental protection for the guidelines, by means of advanced technology and industrialization production, repair, reconstruction of waste equipment, a series of technical measures or the floorboard of the engineering activities [3-4]. Remanufacturing process refers to all kinds of remanufacturing technology is used to repair and remanufacturing product processing, and remanufacturing product meets the performance after the process.

The authors Published by Atlantis Press 1794 remanufacturing products, the production organization form is different, so the specific production process will have differentiation. Usually, the remanufacturing process is shown in figure 1. Retired old products Dismantling Cleaning Inspection and classification Remanufacturing processing
